Title: Production of semiconductor device
Inventor: YAMADA OSAMU
IPC: H01L21/22
Filed: 1992-09-08
Abstract: PURPOSE:To prevent the local generation of n layer due to impurity invading caused by the failures or the like of a protecting film covering a p layer when a p layer is formed on one face side of an n-type board and an n<++> layer is formed on the other face side thereafter to make a pin-construction. CONSTITUTION:After a p layer 2 is formed through impurity diffusion from both sides of an n-type board 1, the impurity diffusion is applied again thereon to form a p<++> layer 5 on both surfaces thereof. Thus, after the p layer and p<++> layer on one side are removed, the surface of existing p<++> layer is covered with a protecting film 4 and an n<++> layer 3 is formed at a place where the layer 2 was removed. If the existing layer 5 is made thicker than the layer 3, even when an n-type impurity would invade because of the failures or the like of the protecting film, it will not reach an n layer 1 to cause an n- conversion.

Title: Optical reader
Inventor: SUGIMURA TOSHIHIKO
IPC: G06K7/10
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To make a bar code reader small and light-weight, to dispense with a light source and to reduce power consumption by arranging a read part with transparent electrode and opaque electrodes, crossed at right angles oppositely and bringing a solid-state image-pickup element into contact between the both electrodes. SOLUTION: For instance, a row electrode 1ab for bar code reading, photodiodes 1aa and columnar electrodes 1ba for bar code reading are located at the positional relationship in Figure (a). The electrode 1ab is a transparent electrode that uses an ITO, and the electrodes 1ba are non-transparent electrodes that use Ni, etc. Because the electrodes 1ba are non-transparent electrodes when external light is made incident, light of that part is cut and light of other parts is transmitted through the electrode 1ab that is a transparent electrode and is made incident on a bar code. The bar code reflects light differently between white and black planes, and the light is made incident on the photodiode 1aa and makes the bar code readable.

Abstract: PURPOSE:To form an element of fine structure with good reproducibility, by etching an insulating film with a plurality of masks and forming an insulating film on a region exclusive of only the region where patterns are partially superposed and using this insulating film as a mask so that the second superconductive metallic film is replaced by an oxidizing film. CONSTITUTION:A Nb film 12, an Al-AlOX film 13, and a Nb film 14 are formed serially in order on a Si substrate 11, and a SiO2 film 15 is formed as an insulating film. Next, a resist film 16 is formed as a mask and so the SiO2 film 15 is processed by a RIE method or the like. Another resist pattern 17 is formed as a mask and so a part of the SiO2 film 15 not etched in the former process is etched. Next, with the SiO2 film 15 used as a mask, anode oxidation is performed to form an anode oxidizing film 18 and a facing electrode 19. With the other resist film used as a mask, the anode oxidizing film 18, the Al-AlOX film 13, and the Nb film 12 are etched to perform patterning. Next, a SiO2 film 20 is formed as a layer insulating film, and so a contact hole 21 is formed by using the resist film as a mask. Successively, after a thin oxidizing film on the surface of the facing electrode 19 is removed by sputtercleaning of it in Ar, a Nb wiring film 22 is formed.

Title: Optical vibration sensor
Inventor: KUSANO HIROYUKI
IPC: G01H1/00
Filed: 1990-09-12
Abstract: PURPOSE:To detect vibration in all directions by inserting a rotating body into a vessel which can rotate by vibration, making light incident into the vessel and detecting reflected light which varies by the rotation of the rotating body by means of a photo interrupter. CONSTITUTION:A rotating body 1 of a metallic or synthetic resin sphere is inserted in an opaque vessel 2. A photo interrupter 3 having a light emitting element for generating visible light or infrared light and a photodetector for receiving reflected light is fixed in the vessel 2. When the rotating body 1 is on a position indicated by a solid circle immediately above a window, light generated from the light emitting element of the interrupter 3 is reflected by the rotating body 1 and incident to the photodetector, so that a light reception output signal from a terminal 5 is maximum. However, when vibration is applied and the rotating body 1 has moved to a position indicated by a broken line circle, the reflected light incident to the photodetector of the interrupter 3 decreases and the light reception output signal from the terminal 5 varies. Therefore, when the rotating body 1 has moved in any three-dimensional direction by vibration, the light reception output signal varies thereby permitting detection of vibration in all directions.

Abstract: PURPOSE: To enhance the comfortable operation and the safety of a warm air heater by comparing the detection signal from a first temperature sensor with a reference temperature signal, and stopping burning in a burner when the temperature of an operating unit becomes a reference temperature or higher corresponding to the reference temperature signal. CONSTITUTION: A microcomputer 17 fetches a detection signal output by detecting the temperature of an operation panel by a first temperature sensor 16 when a warm air heater (e.g. a petroleum fan heater) enters heating, via an A-D converter, and compares the temperature of the panel with the temperature of a reference panel. When the temperature of the operation panel becomes higher than the temperature of the reference panel, the microcomputer 17 stops the operation of a fuel pump 8, interrupts the energization of an electric heater 21, and stops the heating of the fuel vaporizer of a burner to stop the burning. Thus, the comfortable heating of the heater can be conducted, and the safety can be enhanced.

Title: Oscillation circuit
Inventor: HARUNA AKIO
IPC: H03B5/32
Filed: 1984-11-16
Abstract: PURPOSE:To improve the rising of the oscillation output of an oscillation circuit which unitlizes a crystal resonator, etc., by connecting an inductance to the crystal resonator in parallel, and equalizing the oscillation frequency based upon the inductance almost to the oscillation frequency of the crystal resonator. CONSTITUTION:The parallel inductor L is connected to the crystal resonator X1 and the oscillation frequency based upon this inductor L is set nearly equal to the oscillation frequency of the crystal resonator X1. Consequently, an LC oscillation circuit begins to oscillate speedily at the start of oscillation where the power source is turned on. When the oscillation frequency of the LC circuit approxomates the oscillation frequency of the crystal resonator X1, the imped ance of the crystal resonator X1 decreases greatly, so the crystal resonator X1 begins to oscillate instead of the LC oscillation. When the crystal resonator X1 starts oscillating once, the oscillation is carried on at the oscillation fre quency determined by the crystal resonator X1. Thus, the rising of the oscilla tion output is speeded up and the stable oscillation is continued.
