Title: Manufacture of notched insulated gate electrostatic induction transistor
Inventor: NISHIZAWA JUNICHI
IPC: H01L21/336
Filed: 1991-09-24
Abstract: PURPOSE:To prevent the film reduction or wire breaking at the time of forming the polycrystalline silicon of a gate electrode by anisotropic etching by performing the selective oxidation of the same thickness as the depth of a U-shaped groove, with the nitride film left on the sidewall of the U-shaped groove, and preserving the vertical shape of the oxide film made on the sidewall of the U-shaped groove. CONSTITUTION:A U-shaped groove 40' is made on one main surface of a high- resistance silicon substrate 40 by anisotropic plasma etching. A silicon nitride film 43 is stacked all over the surface, and by anisotropic plasma etching, it is patterned so as to leave the silicon nitride film 42 on the sidewall of the U-shaped groove 40', and by selective oxidation, a field oxide film 41 is made. Polycrystalline silicon 42 is stacked all over the surface, and by anisotropic plasma etching, it is patterned so as to leave the polycrystalline silicon 42 on the sidewall of the U-shaped groove 40'. Therefore, the change such as that the shape of the U-shaped groove 40' becomes round is suppressed by the silicon nitride film 43 existing at the sidewall of the U-shaped groove.

Title: Air bag base cloth
Inventor: KATO TAMA
IPC: D03D15/00
Filed: 1990-09-12
Abstract: PURPOSE:To enhance light-weight, flexibility, folding property and durability by constituting air bag base cloth of a textile composed of mixed twist threads of thermoplastic synthetic fiber and fiber of which raw-thread strength is over a specific value and a strength retension ratio at a specific temperature is over a specific value. CONSTITUTION:The air bag base cloth is constituted of a textile composed of mixed twist threads of thermoplastic synthetic fiber and fiber of which the raw thread strength is over 15g/d and a strength retention ratio at 200 deg.C is over 80%, and the textile is a non-surface-coating textile. Consequently, the high-temperature residue occurring due to explosibe combustion at the time of air bag actuation is effectively trapped in between the threads, thereby eliminating danger to a human body and further enhancing light-weight, flexibility and folding properties of the formed air bag. Further, the drop in the air bag burst pressure due to rubbing with module edges at the time of air bag actuation and expanding can be prevented.

Title: Bidirectional linear motor
Inventor: OOHIRA YOUICHI
IPC: H02K41/02
Filed: 1990-09-13
Abstract: PURPOSE:To enable reluctance in the X-axis and Y-axis directions on the primary side by fitting a groove formed to a yoke and the fitting section of a pole core and forming a plane-shaped magnetic path. CONSTITUTION:Rectangular parallelopiped-shaped projections 2a, 2b... are mounted to the top face of square plate-shaped laminated iron plates along the Y axis direction.

Title: Photoelectric conversion circuit
Inventor: YAMADA MASAYUKI
IPC: G01J1/44
Filed: 1988-09-27
Abstract: PURPOSE:To perform an accurate amplification by providing a switching element between a logarithmic transformation element and an output terminal of an operational amplifier in a negative feedback channel for logarithmic amplification and by obtaining an output from the node of the logarithmic transformation element and the switching element. CONSTITUTION:When a light strikes on a photovoltaic element 1, the level of an inversion input terminal OP1 of an operational amplifier 2 is going to rise and that of an output terminal OP3 to fall due to the photoelectromotive force of the element. Since negative feedback is applied to the terminal OP1 from the terminal OP3, however, the rise in the level of the terminal OP1 is suppressed, a potential difference between the opposite ends of the element 1 is maintained to be zero substantially, and a photocurrent IS proportional to the intensity of the light is generated. Since a negative feedback channel is established between analog switches 5 and 6 on the occasion, the photocurrent IS turns to be a collector current of a transistor 3, and a voltage obtained by subjecting this collector current to logarithmic compression apparatus between the base and emitter of the transistor 3. According to this constitution, a voltage being lower by the voltage obtained by the logarithmic compression of the photocurrent IS is outputted to a terminal OU1, and an output of the terminal OU1 is outputted to a terminal T4 through a switching unit 7.

Inventor: ITO TAKEO
IPC: C08L33/04
Filed: 1994-10-07
Abstract: PURPOSE:To prepare a display having a fluorecent layer with a filter attached, thus improved in brightness and contrast. CONSTITUTION:A patterned light-absorption layer 2 is formed on the inside surface of the face plate 1. Then, a pigment dispersion composition is coated to form a blue pigment layer 4B and a fluorescent slurry is applied to provide the blue light-emitting fluorescent layer 5B. At this time, jince the pigment dispersion composition has resistance to overcoating, the composition does not cause migration into the fluorescent slurry. Thereafter, exposure through the mask and development are effected to give the blue pixel 6B with a blue filter attached. Since the pigment dispersion composition has an antinomic properties between the exposed parts and the unexposed parts due to the action of the dispersant, good patterning can be performed. These processes are repeated on the colors 6G and 6R, respectively, to prepare the fluorescent layer with filters attached.

Title: Pressure sensor
Inventor: SAITO MUNECHIKA
IPC: G01L11/02
Filed: 1994-10-07
Abstract: PURPOSE: To provide a highly accurate and surge-free pressure sensor by eliminating an intermediate transmission system while possessing a higher electric insulation performance. CONSTITUTION: A material 3 having photoelastic effect so arranged so as to let a field pressure be applied directly thereto causes a double refraction according to a pressure applied with respect to light passing through the material. The double refraction is measured by means 7-15 to obtain a measured value of the fluid pressure from the value of the double refraction measured. In a pressure sensor thus arranged, the pressure to be measured is applied directly to the material having the photoelastic effect, hence eliminating an intermediate transmission system. This makes possible the obtaining of a highly accurate pressure sensor with limited secular change in the accuracy. In addition, a part of a signal transmission system can be made up of an optical fiber thereby allowing the holding of electric insulation higher between a part to be measured and a measuring device.

Title: Rotary apparatus
Inventor: YANAGIDA TAKAHIRO
IPC: A47L9/28
Filed: 1989-09-20
Abstract: PURPOSE:To perform a quick protective operation when a motor is locked by providing a thermistor and a heat generating resistor contacted with the thermistor which is connected in series with the motor, so that the heat generated from the heat generating resistor can be conducted to the thermistor and vice versa, in a main body of a rotary apparatus. CONSTITUTION:When a motor 33 is rotated normally, a current from an AC power supply 1 flows through the path which comprises a terminal (a) of a switch 37, a diode 36, a resistor 35, a thermistor 34, the motor 33, and a fuse 31. A light emitting element 41 is lit by the voltage generated between the two terminals of the resistor 35. When the switch 37 is changed over into another terminal (b), a light emitting element 44 is lit too. When the motor 33 is locked, the circuit current flowing through the above-mentioned path is increased and the thermistor 34 generates a heat by itself. Thereby, the resistor 35 generates a heat too and the temperature of the thermistor 34 rises further to increase its resistance from the original one, several ohm to several megohm. Thus, the circuit current is reduced and most of the voltage of the power supply 1 is applied to the thermistor 34. Therefore, the light emitting elements 41, 44 are extinguished and a light emitting element 38 is lit to display the abnormality of the motor 33. Thereby, abnormal heating and firing of the motor is prevented promptly.
