摘要： PROBLEM TO BE SOLVED: To provide a vibration mode conversion horn capable of obtaining almost perfect torsional vibration by using a longitudinal vibrator. SOLUTION: The vibration mode conversion horn 4 is constituted by combining a longitudinal resonator 6 having an inputted surface 6a to which a longitudinal vibration is inputted and a torsional resonator 7 having a flange part 7a on a node position. A recessed hollow part 8 is disposed on a radiation surface 6b central part of the longitudinal resonator 6 so that the upper half part of the torsional resonator 7 is not brought into contact with the longitudinal resonator 6 when a radiation surface 6b is connected with the flange part 7a. A plurality of slits 9 which are inclined obliquely with respect to the radial direction of a main body part of the torsional resonator 7 are disposed on the flange part 7a, the longitudinal vibration is converged to a torsional vibration by the respective slits 9 and the radiation surface 7b of the torsional resonator 7 is driven by almost perfect torsional vibration.

摘要： PROBLEM TO BE SOLVED: To uniformly apply ultrasonic vibration to a molten resin having high viscosity and a high flow speed.
SOLUTION: A bending rod 8 is attached to the leading end of the drive horn 5 driven by a vertical vibrator 7 in an inverted T-shape to be arranged in a flow channel 3 and ultrasonic vibration is applied to the molten resin flowing through the flow channel 3 through the bending rod 8. The interval between the inner surface of the flow channel 3 and the outer surface of the bending rod 8 is set to a narrow interval of about 2-5 mm. By this constitution, ultrasonic vibration can uniformly be applied even to the molten resin having high viscosity and a high flow speed.

摘要： PURPOSE:To measure the thickness of a transparent measurement object only by operation from one side with no contact. CONSTITUTION:A first converging lens 4, a second converging lens 5, and a half mirror 6 are put on an optical axis L2 to compose a co-focal point optical system. A measurement object 7 is put vertically to the optical axis L2. When laser beam is emitted from a He-Ne laser oscillator 2 of a light source 1, the laser beam is reflected by the half mirror 6 and led into the first converging lens 4 and converged to the light focusing point F4. When the converging lens 4 moves close to the measurement object 7, the light focusing point F4 moves from the obverse side H side to the reverse side B side of the measurement object 7. The reflected light, reflected by the measurement object 7, passes the first converting lens 4 and the half mirror 6 and is converged by the second converging lens 5 and in this case only the reflected light from the light focusing point F4 is converged to the light focusing point F5. Then, it passes a pin hole 8a of a light selecting plate 8 and is received by a photosensor 9. The reflected light from other points is cut by the light selecting plate 8.

摘要： PROBLEM TO BE SOLVED: To allow an emissive surface to drive by transverse vibration with the same amplitudes everywhere which does not include longitudinal vibration at all. SOLUTION: A tool horn body 2 is formed so as to be a stepped prismatic shape from a large-sized part 2a and a small-sized part 2b. A fixing face 7 for fixing to an elevation mechanism is formed at the upper end part of the large-sized part 2a. An emissive surface 8 for performing working such as welding is formed at the lower end part of the small-sized part 2b. The adjoining two side faces of the tool horn body 2 are provided with a first fixed horn 4 driven by a first longitudinal oscillator 3, and a second fixed horn 6 driven by a second longitudinal oscillator 5, respectively. The face fitted with the second fixed horn 6 in the tool horn body 2 is provided with a first slit 9 corresponding to the first longitudinal oscillator 3. The face fitted with the first fixed horn 4 in the tool horn body 2 is provided with a second slit 10 corresponding to the second longitudinal oscillator 5. The oscillation of the emissive surface 8 is made into the transverse oscillation by providing each slit 9 and 10. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To detect and control the pressure of a hydraulic cylinder, including a transient pressure during pressurizing, with high accuracy. SOLUTION: A tool horn 4 is moved up and down by a hydraulic cylinder 5 to ultrasonically weld a work. An upper room pressure P1 and a lower room pressure P2 are detected by pressure sensors 19, 20 and a pressure difference between them is determined by a calculation controller 21. The pressure of the hydraulic cylinder 5 is calculated on the basis of the pressure difference. The pressure is compared with a set value F' to control a three-position solenoid valve 15 and an ultrasonic oscillator 22 on the basis of the compared results.

摘要： PURPOSE:To shorten the switching time of channels and to branch pulses, one by one, on a time-division basis by providing mirrors which are arranged at equal intervals along an optical path of incidence and a mirror driving mechanism which rotates the mirrors while maintaining a constant tilt angle to incident light. CONSTITUTION:A time-division branching unit 11 is equipped with the four mirror members 15a - 15d which are arranged at equal intervals along the optical path 14 of the incident light 13 and the respective mirror members 15a - 15d are rotated at constant speed by the mirror driving mechanism 16 while holding the tilt angle at, for example, 45 deg. to the incident light 13. Therefore, even when the respective mirrors rotate at all times, the incidence angle of the incident light on the respective mirrors does not vary and the light never deviates from the optical axis. Consequently, the switching time of the channels can be shortened and a pulse laser which has a fast pulse rate can divide pulses, one by one, on a time-division basis.

摘要： PURPOSE:To detect the presence or absence of pits in an easy and sure way and with high accuracy by irradiating a digital disk substrate with the coherent light stopped down to a prescribed diameter and observing the light interference phenomenon that is caused by a pit pattern. CONSTITUTION:When the pits are detected on a digital disk, the digital disk substrates 1 and 11 are irradiated with the coherent light, e.g., an He-Ne laser light 12 which is stopped down to a prescribed diameter at a stage before formation of a metallic reflecting surface and right after the molding. At the same time, the diffracted light is detected by a photodetector 13 like an Si photodiode, etc., for the light interference phenomenon caused by a pit pattern. In this case, the light interference phenomenon is not produced at all in case an area including no pit is irradiated with the laser light. While an extremely intensive interference phenomenon is produced when an area including pits is irradiated with the laser light. Thus it is possible to detect the presence or absence of pits in an easy and sure way and with high accuracy.
