摘要： PURPOSE:To obtain a measured result stable over a long period of time by obtaining a measured value, wherein the variation of a circumferential condition is corrected, by subtracting the deviation data of a reference master from that of an object to be measured. CONSTITUTION:A reference 8 to be used has material quality and a wire diameter almost same to those of an object 5 to be measured and is arranged between lenses 3, 4. In this case, the object 5 to be measured and the master 8 are arranged in parallel so as not to become shadows each other. Deviation is caused by the thermal expansion or contraction of the object 5 to be measured or master 8 according to circumstances but, for the most part, by the mechanical distortion, expansion and contraction of the first measuring systems 3-7 and the second measuring systems 11-14 or the output variation of a light source 1, the intensity of beam and the variation of the center of gravity. Therefore, by subtracting the deviation of the master 8 from the measured result of the object 5 to be measured, the correct measured value of the object 5 to be measured can be calculated.

摘要： PURPOSE:To improve a stability for a measuring value by using a single polarizing laser with a stabilized frequency as a light source. CONSTITUTION:The single polarizing laser with the stabilized frequency, e.g., a frequency stabilized He-Ne laser for the single polarizing oscillation is used as the light source 18. Luminous fluxes of the laser 18 oscillated by a power source 16 for the laser are transmitted to a rotary mirror 3 through a mirror 6. This rotary mirror 3 is provided on a driving system 2 and driven by a driver 1, thereby the luminous fluxes are deflected in an internal of 11-11A and made to be the parallel luminous fluxes 12-12A through a lens 13. These parallel luminous fluxes 12-12A are orthogonally crossed with an axis direction of a columnar object 7 to be inspected, by which interrupted in the time interval proportional to the outside diameter, then transmitted to a detector 9 through a condensing lens 8 and an aperture 17. A photoelectric conversion is made for an output signal of this detector 9, and the signal is transmitted to a signal processing circuit 14 through an amplifier 10. In this circuit 14, an edge is detected by the beam which is interrupted with the object 7 to be inspected, and the outside diameter of the object 7 is obtained by means of counting a clock pulse for the edge interval.

摘要： PURPOSE:To simplify the constitution of an optical system by knowing a distance between a beam waist position and an object to be measured from a rise or fall time of a detected signal, and knowing a position relation before and behind the object to be measured from a scattered light of the object to be measured. CONSTITUTION:When an object 6 to be measured is separated from a beam waist position, the beam diameter which intersects the object 6 to be measured becomes large, therefore, a rise of a signal outputted from a photodetector 5 is varied as a broken line from a full line. When the beam is varied by a distance without varying a distribution state in accordance with an expression I, for instance, like an interval extending from 10 to 90%, it is known by a calculation that an interval corresponding to some prescribed ratio of power is proportional to a beam diameter W. As shown clearly in the expression I, when a distance X is fixed, the beam diameter W is fixed respective of a distance in the scanning direction. Accordingly, the distance X in the optical axis direction is known from the time (t) irrespective of the position in the scanning direction of the object 6 to be measured. In such a way, the constitution of an optical system is simplified.

摘要： PURPOSE:To detect a plurality of data being necessary for averaging, by interception of a light beam at one time. CONSTITUTION:A photodetector 2 detects a silhouette formed when a substance 10 to be measured intercepts a light beam of a light source 1, and a reference level generating circuit 3 generates a voltage level corresponding to an output of the light beam of the light source 1. A D/A converter 4 converts given data at a given timing and a multiplier 5 multiplies an output of the reference level generating circuit 3 and an output of the D/A converter 4. A comparator 6 compares an output of the photodetector 2 with an output of the multiplier 5 and an edge pulse generating circuit 7 generates a pulse at the timing of a rise or a fall of an output pulse of the comparator 6.

摘要： PROBLEM TO BE SOLVED: To provide a marking device capable of making stable resonance without being affected by a resonance frequency number of a tool. SOLUTION: In a marking device in which a marking tool is vibrated by a piezoelectric vibrator for engraving letters, etc., on a subject body, a detection means detects the amplitude of the piezoelectric vibrator as a DC signal, and a drive control means regulates the frequency number of the a drive signal in driving the piezoelectric vibrator to set the level of the DC signal detected by the detecting means within a specified range, so the piezoelectric vibrator driving frequency number is properly regulated for driving the piezoelectric vibrator at a specified amplitude. The amplitude of the piezoelectric vibrator can thus be kept within a specified range, so stable resonance can be made. The resonance can be made without being affected by the resonance frequency of the tool.

摘要： PROBLEM TO BE SOLVED: To provide a method and device for testing gear wherein the affect of a key way provided at a gear which is to be tested is reduced while the distortion of the gear is measured at higher precision than before.
SOLUTION: A reference gear 12 and a gear 3 to be tested are urged using a spring 17 in such direction as they approach each other, for engagement with the reference gear 12 and the gear 3 rotated, the fluctuation in the center- to-center distance between the reference gear 12 and the gear 3 is represented in a function with periodicity using a calculation storage device 19. Here, a function is, for example, a sine function. Then the factor for the function is calculated by a method of least square using the center-to-center distance at a plurality of rotation angles. The amplitude of function calculated from the factor is recognized as an entire distortion amount of the gear 3. The measurement errors caused by play of a travel length measuring device and other device and that caused by a key way are almost cancelled by a method of least square, so the entire distortion amount 8 of the gear δ is measured at higher precision than with previous method.
