Patent JP-S57212417-A (JP)
Title: Liquid crysral dislay device
Inventor: SHINDOU YASUHIKO
IPC: G02F1/1335
Filed: 1981-06-24
Abstract: PURPOSE:To ensure a display with a high contrast even in the high order split driving mode having a large time division number, by setting the product of the refractive index anisotropy DELTAn of a TN cell and the thickness (d) of a liquid crystal at 0.4<=DELTAn. d<=1.0 and at the same time setting an angle formed by a polarizing plate and an absorbing axis within a twist angle when viewed from the direction of the viewfield angle. CONSTITUTION:The time division number can be increased as the product of the refractive index anisotropy DELTAn of a liquid crystal and the thickness (d) of a liquid crystal layer is decreased. However, the optical rotatory power is lost at <=0.4mum time division number, and the quality of display is not secured. The larger the difference between the twist angle beta of the liquid crystal molecule and the twist angle alpha of the absorbing axes of the upper and the lower polarizing plates the more the time division properties can be increased. However, an evil effect is caused by the interference effect of the double refraction light. In this connection a <=20 deg.C angle is ideal for the difference between the angles beta and alpha. When the display electrodes are distributed so as to occupy the greater part of a display area, the greater part of a display screen is divided into a glow part and a nonglow part with no existence of a backgound part. Thus the nonglow part is regarded as a background to reduce the effect of crosstalk.

Title: Laser device
Inventor: AMANO ATSUSHI
IPC: H01S3/0915
Filed: 1985-05-08
Abstract: PURPOSE:To prevent the generation of accidents caused by projection error by connecting a controller to an excitation power source device and supplying electricity to a laser excitation device only when a preset value of the excitation source is under a predetermined value. CONSTITUTION:When the operation starts, a controller 36 sends an off-signal to a switch 66 which turns off a relay XX to make a laser excitation power source 32 capable of being operated. Then the controller 36 releases the power source 32 from its incapability of operation by the rotation of an adjusting lug 24 by a predetermined rotating angle or under and makes the operation possible. The relay XX is turned on and relays X1 and X3 turn on according to the closing of a switch 72, which operates a YAG laser device 38, an He-Ne laser device 40, and a display lamp 42 outside the chamber. At this time, when a foot switch 22 is turned on, a YAG shutter 60 releases an optical path of a laser beam from a YAG rod 54 to allow a YAG laser beam to enter into a laser probe 16. As the devices 40 and 38 operates with interlocking, an operator knows the generation of a laser beam and an accident due to projection error can be prevented.

Title: Magnetoresistive element
Inventor: SAKUMA AKIMASA
IPC: G11B5/39
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To increase the rate of change of reluctance to a value higher than those of magetoresistive elements wherein a nonmagnetic layer is laminated between ferromagnetic layers by using an oxide of chromium M as major phase and constituting M of one or more elements selected from among iron, ruthenium, and iridium to form the ferromagnetic layers. SOLUTION: An Fe-Mn antiferromagnetic film 2, which is 5 nm in thickness, is formed on an Si substrate 1 by ion beam sputtering in order to provide switching bias magnetic fields. The antiferromagnetic film 2 is subjected to heat treatment and then two films of Cr1-xFexO2 (x=0.0, 0.03, 0.05, 0.07) ferromagnetic layers 3 and 5, which is 3 nm in thickness, are laminated thereon with a Cu nonmagnetic layer 4, which is 3 nm in thickness, in-between. For the ferromagnetic films 3 and 5, an oxide of chromium M is used as major phase and M is constituted of one or more elements selected from among iron, ruthenium, and iridium. The magnetoresistive element uses a novel film constitution and thus obtains a rate of change of reluctance not less than 10%.

Title: Insecticidal composition
IPC: A01N25/22
Filed: 1992-03-25
Abstract: PURPOSE:To obtain the subject composition, capable of suppressing the decomposition of empenthrin and preventing an offensive smell from emitting by mixing the empenthrin which is an odorless and volatile mothproofing agent with n- octadecyl-3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate. CONSTITUTION:The objective new mothproofing and insecticidal composition is obtained by blending empenthrin with n-octadecyl 3-(3,5-di-t-butyl-4- hydroxyphenyl)propionate which is an antioxidant ingredient. This composition can be used as a mothproofing agent for clothes. The mixing ratio of the antioxidant ingredient to the empenthrin is preferably about (1:10) to (1:50) weight ratio. Since the n-octadecyl 3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate used herein has a low melting point and relatively high solubility in the empenthrin, melt mixing can readily be carried out without using a solvent such as acetone. Furthermore, the n-octadecyl-3-(3,5-di-t-butyl-4-hydroxyphenyl) propionate is not deposited at low temperatures. In addition, since this compound is colorless, a substance impregnated therewith is not colored.

Title: Production of photomask
Inventor: SUZUKI EIJI
IPC: G03F1/00
Filed: 1981-06-24
Abstract: PURPOSE:To produce a photomask containing a high-accuracy light shielding pattern in an easy and stable way, by forming first a resin pattern by exposing an image to light at the side of a glass substrate when the photomask is produced by a lift-off process. CONSTITUTION:A positive photosensitive resin film 12' is formed on a single surface of a glass mask substrate 11, and the pattern exposure 13 is carried out at the side of the substrate 11. The film 12' is developed to form a positive photosensitive resin pattern 12 on the substrate 11. Then a light shielding material film 14' is formed, and the light shielding film material on the pattern 12 is removed together with the film 12'. The film 14' on the substrate 11 is separated from the film 14' on the resist pattern 12. As a result, no loss is caused to the film 14 due to the lift-off process. Thus a photomask of high accuracy can be produced in an easy and stable way.

Title: Power supply device
Inventor: NAGASAWA YASUO
IPC: H05K1/02
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent the bounce of a surge voltage, even in the case of incorporating a step-up type higher harmonic current suppression circuit. SOLUTION: When a surge voltage by a lightning surge is applied to a power supply device, a voltage is generated when a choke coil 16 discharges its own energy. However, when the generated voltage in the choke coil exceeds a predetermined level, the voltage is discharged by a discharging gap 56. Therefore, the bounce of the surge voltage by the choke coil 16 can be suppressed. Accordingly, without obstructing the suppressing effect of a higher harmonic current by a step-up circuit 13, an internal circuit can be protected even if the surge voltage is applied thereto.
