Patent JP-H06251548-A (JP)
Title: Tape cassette
Inventor: SAKURAI SATOSHI
IPC: G11B23/087
Filed: 1993-02-23
Abstract: PURPOSE:To absorb vibration of a reel base by a reference table and to improve the quality of a tape cassette by forming an annular recessed part on a lower reel flange and fitting an engaging piece of the annular reference table consisting of an elastic rubber to the recessed part. CONSTITUTION:A reel at the tape feeding side and a reel at the tape take-up side are pressed to the side of a lower half by a reel pressing spring which is supported with an upper half of the tape cassette, and the lower reel flange 6a is supported with the reel base through the reference table 13. The annular recessed part 14 is provided on the flange 6a, and the engaging piece 15 of the annular reference table 13 consisting of the elastic member is fitted to this recessed part 14 by a force-fitting and fixed. Consequently, even though the vibration generated from a motor, etc., is transmitted to the reel base at the time when the tape cassette is operated, it is absorbed in the reference table 13 of the elastic member and not transmitted to the tape reel 6. The vibration transmitting to the tape is thereby eliminated, and the quality of the tape cassette is improved.

Title: Web coating device
Inventor: KISHIDO TAKESHI
IPC: B05C5/00
Filed: 1989-02-13
Abstract: PURPOSE:To prevent a contact accident at a boundary region between a web holding part and a web not holding part by making the amt. of gas to be injected at the boundary region larger than that at the other region on the web holding surface. CONSTITUTION:A coater 2 and a gas injector 11 are arranged practically in opposition to each other with a continuously traveling web 3 in between. The amt. of gas to be injected from the injector at the boundary region 11c between the web holding surface 11a and web not holding surface 11b of the injector is made larger than that at the other region of the web holding surface 11a. As a result, the rapid depressurization of the gas contributing to the floating and supporting of the web 3 at the boundary region 11c is prevented, and the contact accident of the web 3 at the boundary region 11c is prevented.

Title: Dc motor
Inventor: GOTOU MAKOTO
IPC: H02P6/28
Filed: 1978-03-23
Abstract: PURPOSE: To improve the effect at low speed rotation by providing the first and second control means to control the current flow-in and -out of a multi-phase coil and switching a driving system using the current route switching means of the neutral point of the multi-phase coil and the DC power supply.  
     CONSTITUTION: The position detecting rotor 5 is mounted around the shaft of the rotor 1 on which a field magnet with a number of poles is magnetized. The phase DC voltage corresponding to the rotary position of the three-phase driving coils X, Y, and Z detected by this rotor 5 is individually applied to the bases of the transistors (Tr) Q1 to Q6. At low speed rotation, in the first flow-in current control circuit the largest potential phase Tr of the base voltage and in the second flow-out current control circuit the smallest potential phase Tr are most activated and switched according to the change of the base voltage. At low speed rotation, TrQ13 turns off and the neutral point potential of the neutral coil in the three-phase coil keeps constant, thus always supplying current to the two-phase coil. At high speed rotation, TrQ13 fully turns on and TrQ10 to Q14 turn off, thus supplying current to the one-phase coil.

Title: Method of driving liquid crystal display device and projection type liquid crystal display device
Inventor: OGAWA TETSU
IPC: G09G3/36
Filed: 1989-02-14
Abstract: PURPOSE:To prevent image display characteristics from deteriorating by supplying a different potential relation between a display signal supplied to a signal line and a scanning signal supplied to a scanning line corresponding to the intensity or energy of light which is made incident on the liquid crystal display device. CONSTITUTION:Signal lines and scanning lines are arrayed in a matrix shape and thin film transistors are used as switching elements to drive liquid crystal. This liquid crystal display device supplies the different potential relation between the display signal supplied to the signal lines and the scanning signal supplied to the scanning lines corresponding to the intensity or energy of the incident light. Therefore, the relation between a positive stress application period and a negative stress application period under driving conditions is optimized. Consequently, stable operation which is free from display characteristics is secured without reference to the intensity or energy of the incident light.

Abstract: PURPOSE:To preferentially make hydrogen evolve on a hydrogen evolution layer when oxygen supply is discontinued to prevent irreversible performance of an oxygen electrode by arranging on an electrode side a catalyst layer haivng lower hydrogen overvoltage than that of an oxygen reduction catalyst in an oxygen electrode of an electrochemical cell. CONSTITUTION:The first layer is a hydrogen evolution layer 1 comprising a mixture layer of Raney nickel, carbonyl nickel, and a copolymer of tetrafluoroethylene-hexafluoropopylene, the second layer is a porous nickel layer 2 which does not apply water repellent treatment, the third layer is an oxygen reduction catalyst layer comprising a mixture of carbon carrying platinum and polytetrafluoroethylene, and the fourth layer is a waterproof layer 4 comprising a stacking layer of a porus polytetrafluoroethylene and the copolymer of tetrafluoroethylene and hexafluoropropylene. When oxygen or oxygen containing gas is supplied, electrolytic reduction reaction of oxygen undergoes on the interface of the porous nickel layer 2 and the oxygen catalyst layer 3 or in pores of the oxygen reduction catalyst layr 3. When oxygen supply is discontinued, hydrogen preferentially evolves on the hydrogen evolution layer 1 because this layer is near to a counter electrode and its hydrogen overvoltage is low.

The incident light signal of the wavelength lambda2 on the optical fiber 1 is, therefore, reflected by the interference film filter 5 even if said light is propagated through the interference film filter 4 to the optical fiber 2. The crosstalk in the optical fiber 2 is thus prevented. The crosstalk generated when the titled device is used for a wavelength multiplex communication system is decreased to the lowest possible level.
