Title: Ultrasonic wave motor
Inventor: KOMENO HIROSHI
IPC: H02N2/00
Filed: 1987-10-20
Abstract: PURPOSE:To reduce abrasion, by fixing the frictional member of composite plastics material including carbon fiber, pulverulent fluorocarbon resin, and matrix resin, on the surface of contact. CONSTITUTION:So far as an ultrasonic wave motor is concerned, on the surface of a piezoelectric unit 1, a metallic oscillating body 2 is bonded and fixed, and on the contact surface of a mover 4, the frictional member 3 of composite plastics material including carbon fiber, pulverulent fluorocarbon resin, and matrix, at least is firmly fitted. The oscillating body 2 and the frictional member 3 come in contact with each other in the state of pressure applied by a tightening force, and by applying the high-frequency electric-field of resonance frequency to the piezoelectric unit 1, the progressive wave of ultrasonic wave oscillation is generated on the oscillating body 2. By the frictional member 3 coming in contact with the surface of the oscillating body 2, through a frictional force between the member 3 and the oscillating body 2, the mover 4 is driven. As a result, by setting the frictional member 3 of the carbon fiber and the like, stable brake torque can be obtained.

Title: Inductance element and production thereof
Inventor: KOBAYASHI HIROAKI
IPC: H01F27/28
Filed: 1992-09-04
Abstract: PURPOSE:To realize an inductance element in which troubles, e.g. fluctuation of characteristics or short circuit, are suppressed by employing a coil body obtained by cutting and pressing a conductor, and a core to be inserted into the coil body. CONSTITUTION:A ferrite core 7 is inserted into a press coil 3 produced of a hoop through punching and press and then they are embedded in ferrite resin 14 to constitute a mold choke coil 15. Grooves 7a, 7b are made in the upper and lower faces of the ferrite core 7 and the upper and lower curved parts 3a, 3b of the press coil 3 are fit, respectively, in the grooves 7a, 7b thus securing the press coil 3 and the ferrite core 7 each other. The press coil 3 is exposed, at the terminal parts 4, 4 thereof, to the outside of the ferrite resin 14. This method facilitates molding and promotes mechanization in the production of mold choke coil. Furthermore, deformation of press coil is prevented by the injection molding pressure at the time of molding of ferrite resin.

IPC: B60L50/16
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a relay circuit device for emergency use excellent in reliability for its operation although an open relay is integrated in it. SOLUTION: A load driving circuit for emergency use integrating an open relay 3 energized in an emergency is provided, and when an emergency case occurs, a control circuit 8 energizes the exciting coil of the open relay 3 manually or automatically, in order to finally feed power to the load. Since a contact refreshing signal which is a command signal to energize the exciting coil different from a command signal to energize the load is inputted in the contact control circuit 8 (refreshing means) periodically or with a certain frequency pattern for occurrence, an oxide film on the contact of the open relay 3 corresponding to that part is removed, and its conductivity is enhanced. As a result, a relay circuit device for emergency use excellent in its reliability can be materialized despite an open relay used in it.

Title: Splice synchronizing method and system
Inventor: ARAN JIEI PITSUPUKOON
IPC: B65H23/04
Filed: 1994-10-04
Abstract: PURPOSE: To accurately synchronize splices with reproducibility of a component web splice in the case of altering an order. CONSTITUTION: The method for splices synchronization in each of component webs used in making a composite corrugated paperboard web independently measures a length of each component web between a splicer on a dynamic real time based where it is supplied and a downstream cutoff apparatus where the synchronized splices are cut out in a short length of web in which they are contained. A real time measurement of each component web has continuous monitoring of web lengths subject to change while running through variable length storage areas, and an initialization procedure whereby an initially unknown length of component web in its respective storage is decided. The system has a calibration procedure by which the various devices used to measure running web lengths throughout the system are all calibrated to a master device which controls the total web length for each other.

Title: Test signal selecting path for gate array
Inventor: KAMATA TOSHIYUKI
IPC: H01L27/04
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To reduce consumed electric power in the case of the actual operation of a gate array without lowering the rate of failure detection by sending out a selection signal to a following circuit only when mask means (AND circuit) requires the selection signal. SOLUTION: A selection signal generating circuit 4 generates a selection signal of selection signals (e), (f) supplied from the register 3 of a specified address in a gate array and outputs it. An AND circuit (AND gate) 5 masks the outputting of the selection signal to a reselection signal (p) as far as a mask release signal (o) is not supplied from the register 3. When the release signal (o) is supplied, the AND gate 5 outputs the selection signal to the reselection signal (p). A selection circuit 6 therefore outputs a peripheral circuit A test signal (a) as a test signal (I). In addition, since an external output selection signal (n) is H, an output selector 7 outputs the test signal (I) to an output signal (m). Thus the peripheral circuit A test signal can be monitored, and the detection of failure becomes possible.

Abstract: PURPOSE:To measure dynamic quantity with high accuracy even when a severe mag netic field or heat source is present in the outside, by providing a layer composed of a superconductive material to the surface layer of a mechanical quantity/quantity-of- electricity converting sensor. CONSTITUTION:A ceramics layer 2 relatively inferior to heat conductivity is arranged to the inside of a layer composed of a superconductive material and a copper alloy 3 having good heat conductivity is subsequently fixed to the inside of said ceramics layer 2. Further, a holder 4 and two rectangular piezoelectric elements 5 having polariz ing axes in mutually opposite directions and bonded to each other are mounted therein. A U-shaped slit 6 by laser processing is formed to the center of this piezoelectric rectangular plate and the part surrounded thereby is set to a bending vibrator 7 having a cantilevered structure and output take-out electrodes are provided to both upper and lower surfaces thereof. The vibrator 7 vibrates at acceleration applied from the outside and acceleration can be measured on the basis of the voltages generated in the electrodes at this time. By this constitution, the resistance against the noise to the disturbing agitation of an external electromagnetic wave is enhanced and the effect of heat radiation is excluded even when there is a heat source in the vicinity.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject optically active compound especially useful as an intermediate for a β-lactam compound by reducing 4-sulfenyl-substituted acetoacetic acid ester with baker's yeast in the presence of a specific compound, thereby proceeding the reaction in a short time.

A reduction product can be produced in high enanthio-selectivity by the reduction of an acetoacetic acid ester derivative having sulfenyl group at the 4-site. Especially, an optically pure reduction product of R isomer is produced by using ethyl 4- phenylthioacetoacetate. The reduction product can be converted into β- hydroxyamide and induced to a β-lactam compound by photo-extension reaction.

Abstract: PURPOSE:To improve forward visibility, in a handlebar interlocking type head lamp device, by enlarging the oscillation angle of a head lamp when a handlebars steering angle is small, and obtaining attenuation characteristics approaching the handlebars steering angle gradually as the steering angle is enlarged. CONSTITUTION:When a steering shaft 2 is rotated by steering handlebars, a driver lever 15 oscillates, and a driven lever 13 oscillates by engagement of a drive pin 16 with a slit groove 14 to rotate an intermediate rotating shaft 8 anticlockwise.
