Patent JP-H0192712-A (JP)
Title: Optical switch
Inventor: OBARA YUICHI
IPC: G02B26/02
Filed: 1987-10-03
Abstract: PURPOSE:To obtain an optical switch by which a light shielding property between end faces of an optical fiber is satisfactory, and also, a coupling loss at the time of optical coupling is small by mixing a photoabsorbing agent into a light shielding piece. CONSTITUTION:When a thin wall part 19b of a light shielding piece is positioned between end faces of optical fibers 15A, 15B, an optical path is cut off, and when an operating shaft 13 is depressed in such a state, a light shielding piece 19 descends, the thin wall part 19b comes out of between the end faces of the optical fibers 15A, 15B, therefore, the optical path conducts. Subsequently, when the depression of the operating shaft 13 is released, the operating shaft 13 is returned to its original state by a repulsion of a spring 14, and the light shielding piece 19 cuts off the optical path. Also, since a photoabsorbing agent is mixed into at least the light shielding piece 19, the light shielding property of the light shielding piece 19 is improved. In such a way, a light beam between the end faces of the optical fiber at the time of light shielding is cut off surely, and also, an interval between the opposed fiber end faces can be made small enough, therefore, a coupling loss at the time of optical coupling decreases, and an optical switch whose coupling rate is satisfactory is obtained.

Title: Pressure developing apparatus
Inventor: NAGATA OSAMU
IPC: B41M5/124
Filed: 1989-09-25
Abstract: PURPOSE:To surely prevent a cam from overshooting due to relief back force of press rollers by a method wherein a one-way rotating assembly connects to the cam when the torque of the cam is transmitted to the one-way rotating mechanism, so that the rotation of the cam is restricted. CONSTITUTION:When pressure development is performed, a sheet of micro-capsule paper 17 and a sheet of color developing paper 13 are laminated together partly inserted between first and second pressing rollers 2 and 3. Then, a control key 9a is moved away from a key groove 10a in a collar 10 by a solenoid 9. Thereby, a spring clutch 5 is connected, and the torque of an input shaft 5c is transmitted to an output shaft 5d to rotate the output shaft 5d. A cam gear 5b rotates with the rotation of the driving shaft 5d, and an auxiliary shaft 7 is turned in the normal direction by the cam gear 5b, however, a relative rotation is not produced as the rotation speed of the auxiliary shaft 7 coincides with that of a clutch gear 7a.

Inventor: ARAI KAZUO
IPC: C25D21/12
Filed: 1983-12-29
Abstract: PURPOSE:To correct the characteristic of a plating liquid, plating current and diffusion voltage to the set values with respect to the prescribed beta bruss rate with high accuracy by measuring on-line and continuously the characteristic of the plating liquid, the coating weight of copper and zinc and the beta brass rate after the thermal diffusion treatment and controlling on-line and automatically the characteristic of the plating liquid, plating current and diffusion voltage. CONSTITUTION:A steel wire 1 is passed successively through a copper plating cell 6 and a zinc plating cell 7 and is thus plated with copper and zinc. The plated wire is passed through a diffusion soaking cell 10 and is subjected to brass alloying by the thermal diffusion treatment. The pH, temp., specific gravity, concn., etc. of the plating liquid are continuously measured by a fluorescent X-ray analysis device 15 and a measuring device 16 for the characteristic of the plating liquid in this stage and the coating weight of the copper and zinc on the steel wire 1 and the beta brass rate after the thermal diffusion treatment are on- line measured by an X-ray diffraction device 18. The characteristic of the plating liquid, plating current and diffusion voltage are thus on-line and automatically controlled and are corrected to the set values with respect to the prescribed beta brass rate with high accuracy.

Title: Piezoelectric electroacoustic transducer
Inventor: INOUE TOSHIHIDE
IPC: H04R17/00
Filed: 1986-10-20
Abstract: PURPOSE:To improve the electroacoustic conversion efficiency by coupling a recessed ridge of a piezoelectric film having an electrode formed to both sides and shaped as rugged stripes with a support base having a curved face. CONSTITUTION:In the piezoelectric element 1, a polyfluoride vinylidene film is formed while its cross section is a waving shape rugged stripe and a conductor foil is laminated to both sides to form the electrode and the low ridge line is coupled with a curved face of the support base 2 having a curved face constituting a part of a cylinder wall face. For example, in applying one polarity signal, the piezoelectric element 1 is expanded in the fatial direction and the peak of the waveform is increased and expanded and in applying the signal of the other polarity, the contraction, expansion and contraction are repeated conversely to obtain an acoustic output. Moreover, since the fatial direction expansion/contraction of the piezoelectric element efficiently is transduced into the forward/backward vibration, the acoustic radiation efficiency is improved.

Filed: 1990-09-18
Abstract: PURPOSE:To operate a device with 1.5V battery voltage and to read out data at a high speed by pairing bit lines and providing sense amplifiers in both ends of each pair. CONSTITUTION:Bit lines 4 are paired, and sense amplifiers (transistors TRsQ8 to Q13 and TRsQ20 to Q25) are provided in both ends of each pair.

Title: Cylinder structure for power steering device
Inventor: HOSHINO YOJI
IPC: B62D5/12
Filed: 1990-09-20
Abstract: PURPOSE:To restrict a feeling of resistance or abnormal noise at the time of steering by engaging a cylindrical part in a dead space of a cylinder tube. CONSTITUTION:For filling actuating liquid in a cylinder tube 1, air in the cylinder tube 1 is drawn by vacuum, where the suction force for that is limited, so air in proportion to the volume of a dead space remains in the cylinder tube 1. A cylindrical part 7 is therefore engaged in the dead space 6 between an end part of a hollow of the cylinder tube 1 and a stroke end of a piston 4 to reduce the volume of the dead space 6 so as to make a space where air is stored small and reduce a penetration quantity of air into the actuating liquid at the time of power steering action. Stick slip phenomenon or chattering vibration can thus be restricted, thereby a feeling of resistance or abnormal noise at the time of steering can be restricted.

Abstract: PURPOSE:To shorten the file restoring time by forcibly outputting the record that is not updated even after a fixed time to a journal as an update history when a file is restored due to a fault. CONSTITUTION:When the file record of an external storage 3 is registered, a record start means 11 outputs an update history to a journal and at the same time a timer 16 is set to the record for the forcible recording purpose. If no update is performed even after a fixed time, a forcible recording means 12 outputs forcibly the update history to the journal and sets again the timer 16. When the update is performed within a fixed time, a normal recording means 13 outputs instantaneously the update history to the journal and sets again the timer 16. Then a record ending means 14 cancels the set timer 16 at deletion of the record. A file restoring means 15 restores a file based on the data obtained at a fixed time before the occurrence of a fault. As a result, the file restoring time is shortened.
