摘要： PURPOSE:To obtain a gyro which is easily supported and fixed and has good stability by making a vibrational body structure symmetrical in every direction of a discoid dumbbell and performing driving and detection. CONSTITUTION:Vibrators 11A and 11B are discoid and a connecting rod 21 as a connecting member connects between those central axes. Then, this connecting rod 21 is supported on its center by a collar 31 for fitting as a supporting member. Further, piezoelectric elements 41a-41c are provided to the vibrators 11A and 11B as a driving means. Then, taking the vibrator 11B as an example like figure (b), the doughnut-plate-shaped elements 41a and 41c are stuck to both surfaces of the vibrator 11B and the element 41b for driving and feedback is stuck to the central part of the element 41a. The connection of the vibrator 11B of one side alone is shown in figure (b) but actually, a detected signal from the vibrator 11A of the other side is added to improve sensitivity. Then, a piezoelectric element 51 is fitted to both sides of the collar 31 for fitting as a detection means.

摘要： PURPOSE:To enhance the stability of the titled gyroscope by miniaturizing said gyroscope as a whole and generating well-balanced vibration, by constituting the vibration gyroscope used in order to control the direction and posture of a motion body of a square shaped vibrator formed by adhering a piezoelectric element to respective arms. CONSTITUTION:A first base 13 and a second base 14 each forming a square shape as a whole are formed using a constant elasticity alloy such as a Ni- SPAN-C alloy and respectively used as a first arm 11 and a second arm 12 to constitute a vibrator 10. Herein, the shape of each of the first arm 11 and the second arm 12 is set to a rectangular cross-section but the aspect ratio thereof is slightly differentiated to shift the resonance frequencies in X- and Y- directions to prevent the generation of spurious vibration. Thereafter, PZT or ZnO type piezoelectric elements are adhered to the arms 11, 12 and the vibrator 10 is fixed to a base stand 52 through a support rod 51. By this method, the number of drive and detection parts are increased and a vibration gyroscope having high sensitivity and reduced in spurious offset output is obtained.

摘要： PURPOSE:To reduce the spurious offset output and to improve the S/N by constituting an oscillator with a single substance of piezoelectric materials which are formed to a tuning fork shape and has a low coefficient of temperature and suppressing the secondary oscillation to generate oscillation of only the primary oscillation mode in the oscillator. CONSTITUTION:A tuning fork type oscillator 10 having the first arm 12 and the second arm 13 consists of a single substance of piezoelectric materials. A driving-side electrode 2 is attached to the first arm 12, and a driving-side electrode 3 is attached to the second arm 13. When the width of both arms 12 and 13 denoted as (da) and the depth of the cut between arms is denoted as la, a length le of electrodes 2 and 3 is made approximately equal to 0.5la and a width We of them is made approximately equal to da/3, and these electrodes are so attached that their lower ends are lower than the bottom of the cut between arms by a minute length DELTAle. Thus, the oscillator 10 minimizes a capacity ratio related to the figure of merit as the oscillator and suppress generation of oscillation in the tertiary oscillation mode which causes the spurious offset output.

摘要： PURPOSE:To improve reliability, facilitate manufacture, and reduce cost by generating vibration by a single body of piezoelectric material. CONSTITUTION:A sound piece 10 is a vibrator in the shape of a rectangular prism and made of a single body of piezoelectric material, and a polarizing treatment is performed as shown by a reverse arrow. Electrodes 20, 22, and 24 for driving are arranged on an y2 surface and an x1 and an x2 surface of a vibrator 10 and electrodes 21 and 23 for detection are arranged on an x1 surface and an x2 surface of the vibrator 10. The electrodes 22 and 24 are connected and the electrodes 23 and 24 are grounded. When an AC signal is applied to a terminal fy, the vibrator vibrates in primary vibration mode in the same direction as the direction of polarization and is rotated at an angular velocity OMEGA around a long-axis direction, thereby causing vibration at right angles to the direction of polarization. Consequently, an AC signal having an amplitude proportional to the angular velocity OMEGA appears at a terminal fx.

摘要： PURPOSE:To reduce the connection between the input and output as much as possible, by the piezo-electric ceramic on the extraction side into two pieces to make the bonding position hard to deviate. CONSTITUTION:A piezo-electric ceramic 2 for driving is bonded on one side contacting a chamfered part of a sound piece 1 having a chamfered section 4. Piezo-electrics 3 and 3' for extraction are bonded on two sides adjacent to the ceramic 2 bonded surface one per each in such a manner as to be arranged along the corner contacting the surface opposite to the piezo-electric ceramic bonded surface on the driving side. Then, when a signal is inputted into the ceramic 2, two vibration of degenerated vibration mode are excited in the directions X and Y. The same amount of charge but opposite in the polarity is generated on the ceramics 3 and 3' by both the vibrations to be canceled. Therefore, no output will generated during the non-rotation period. With rotation, the charge generated in the ceramics 3 and 3' becomes so different in the amount as to generate an output. This enables correct detection of rotating components alone.

摘要： PURPOSE:To enable stable detection of angular speed with limited connection between the input and output, by dividing a piezo-electric ceramics for driving or extraction in two on the same arm of a tuning fork to be bonded along the corners thereof so that deviation in the bonding position may be made hard to occur. CONSTITUTION:Each two sheets of piezo-electric ceramics 2 for driving are bonded on sides of both arms of a tuning fork 1 sandwiching respective arms. And each two sheets of piezo-electric ceramics 3 for extraction are bonded on two outer surfaces of the tuning fork. At this point, the ceramics 2 are arranged along internal corners of the tuning fork while the ceramics 3 are done along the corners contacting the sides of the tuning fork. Then, when a signal is inputted into the ceramics 2, an X-axis vibration is excited. But the electric charges of the four sheets of ceramics 3 becomes equal in the nega tive and positive level and hence, no output is generated because of canceling therebetween. Then, when rotation is done, the Y-axis vibration is generated so that electric charges generated in the ceramics 3 will be all the same in the polarity and added outputs be generated. Thus, a stable detection of angular speed can be detected.

摘要： PURPOSE:To enable accurate detection of rotating components alone of a gyroscope, by dividing the piezo-electric ceramic on the driving and extraction sides into two pieces each. CONSTITUTION:A pair of piezo-electric ceramics 3 and 3' for extraction are bonded on both width-wise ends of one of sides of a sound piece 1. Remaining one pair of driving piezo-electric ceramics 2 and 2' are bonded along the ends not contacting the non-ceramics 3 and 3' bonded surfaces of two sides adjacent to the ceramics 3 and 3' bonded surfaces one per each. Then, the X-way vibration is driven on the ceramics 2 and 2' but the Y-way vibration will not generate because of the offset of charges. On the extraction side, the Y-way vibration is extracted but the X-way vibration will not be because of the offset of charges. Thus, no output is generated during the non-rotation period. Then, when the bonding position of the piezo-electric ceramics deviates across the width of the bonded surface, the driving force of the Y-way bending vibration generated in the respective piezo-electric ceramics will not change on the driving side. Also on the extraction side, the electric charge generated by the X-way vibration will not change.

摘要： PURPOSE:To obtain a microorganic activator, used by dissolving a chitinous substance in a specific proportion in a pyroligneous solution at a specific concentration, further adding a very small amount of a metallic substance consisting essentially of bivalent iron thereto and diluting the resultant mixture in application and having antimicrobial activitv esrecially against phytotoxic germs in lawn of golf links. CONSTITUTION:The subject activator is produced by dissolving a chitinous substance in an amount of 1+ or -0.2wt.% in 50+ or -10wt.% pyroligneous solution and further adding 10-1000ppm metallic substance consisting essentially of bivalent iron thereto and diluting the resultant mixture to 200-1000 times in use. Since the pyroligneous solution and chitosan in cooperation proliferate microorganisms (e.g. actinomyces) capable of exhibiting antimicrobial activity against noxious germs of the genuses Rhizoctonia, Fusarium, etc., in soil, large patch, brown patch, red rust, etc., derived therefrom can be prevented from occurring to remarkably reduce the amount of conventionally sprayed agricultural chemicals. The activator can be applied even to agriculture and landscape architecture. The metallic substance is added for providing plants with resistance to diseases and water-soluble Mg, Mn, Mo, B, Zn, Cu, etc., are used in addition to the bivalent iron.

摘要： PURPOSE:To detect an angular velocity with high accuracy from a phase variation of a vector of each voltage, by constituting the titled sensor so that a phase difference angle made by a vector of an output voltage by the angular velocity and a vector of an null output voltage at the stationary state becomes 90 deg., by an auxiliary driving means. CONSTITUTION:This sensor is provided with a detection side auxiliary driving piezoelectric element 25, in addition to piezoelectric elements 21-24 which are usually required for a driving detection, by which a null output voltage is held at a small stable value, and a phase difference to a component generated by a rotation of a vibrator 1 is set 90 deg.. Also, by combining the piezoelectric element 21 for driving and the piezoelectric element 23 for a feedback, an automatic vibrating circuit is constituted, and by connecting a driving side driving signal to the detection side auxiliary piezoelectric element 25, they are connected so as to generate a minute and stable null output voltage at the time of stillness. In this state, by a phase detecting circuit 42, a phase difference between a detecting signal and a driving signal is detected, and by amplifying its value by an amplifying circuit 43, an angular velocity can be detected with high accuracy.
