Title: Negative pulse reception circuit
Inventor: TAKEI TOORU
IPC: H03K19/0944
Filed: 1983-08-18
Abstract: PURPOSE:To attain miniaturization, simplicity and low cost of the titled circuit by using a depletion FET as the 1st stage to drive only a positive power supply without using a negative power supply. CONSTITUTION:When no negative pulse signal is applied to an input terminal 31, the depletion FET32 is turned off and some current flows, then a transistor (TR) 35 is turned on and an output terminal 37 goes to an earth potential. When a negative pulse signal is fed in this state, the FET32 is turned on, the TR35 is turned off and the output terminal 37 goes to a high potential. When this negative pulse signal is restored to the earth potential, the FET32 is turned off, the TR35 is turned on and the output terminal 37 goes to the ground potential. Even if the negative pulse signal is inputted, since a positive pulse is outputted without using a negative power supply, the circuit is miniaturized, simplified and constituted inexpensively.

Inventor: JINGUUJI KANAME
IPC: H01L21/205
Filed: 1984-07-20
Abstract: PURPOSE:To obtain a deposited substance in the desired shape on a substrate with high accuracy by synchronized irradiation of laser lights where the laser light pulse for raw material gas reaction is irradiated horizontally for substrate while the laser light pulse for heating substrate is irradiated vertically. CONSTITUTION:A substrate 8 within a reaction chamber 9 is irradiated through a mirror 5 with light beam control with light beam operation system 3 controlled by a microcomputer 13 using a ruby laser light pulse as the light source 1 for heating substrate. As the light source 2 for reaction, an excimer laser light pulse is used, it is then squeezed with a cylindrical lens 4 and it enters horizontally the substrate 8. A timing pulse is sent to each laser from a comon clock 11 through a variable delay circuit 12, the lasers are synchronized and oscillation period of reaction laser is a little delayed from the heating laser. According to this structure, it is unnecessary to irradiate the substrate with short wavelength, high energy light beam in high intensity and any thermal damage is not generated on the substrate. Moreover, since the substrate is heated in synchronization with the reaction laser light, temperature distribution of substrate is not destroyed during reaction of raw material gas (during irradiation of reaction laser pulse) and a high accuracy pattern can be deposited.

Title: Light-receiving element
Inventor: FUJII EIJI
IPC: H04N5/335
Filed: 1985-07-09
Abstract: PURPOSE:To condense beams onto a light-receiving section by increasing a refractive index with a proceeding to a long surface of an inter-layer insulating film on the light-receiving section while flattening the surface. CONSTITUTION:Light-receiving sections 12 and transfer sections 13 are formed, and an oxide film 14 is grown in approximately 1000Angstrom through a thermal oxidation method or a CVD method. A mixed film of an oxide film and an Si3N4 film is used as a target, an inter-layer insulating film 15 consisting of multilayer films is shaped through a multi-sputtering method while increasing the ratio of the Si3N4 film, a resist is applied onto the insulating film 15 in approximately 3mum, and the insulating film 15 is formed to a flat shape through an etching- back method. Since the inter-layer insulating film 15 functions as a flat microlens, beams projected near the transfer sections 13 are also condensed onto the light-receiving sections 12. That is, the numerical aperture of the light- receiving section 12 increases by the operation of the inter-layer insulating film 15. Since the insulating film 15 is flattened, a light-shielding section is also shaped easily on the inter-layer insulating film 15, thus also improving the characteristics of the prevention of a smear, etc.

Title: Car washing machine
Inventor: DENDA MAMORU
IPC: G05B23/02
Filed: 1983-08-17
Abstract: PURPOSE:To speed up the detection of an abnormal spot with great promptitude as well as to make the cause of trouble seizable in an accurate manner, by storing a trouble happening spot and a car washing process in time of the occurrence of trouble in memory by means of a signal out of a sensor which perceives a state of performance in each operating unit, while displaying it on a display unit. CONSTITUTION:An input apparatus 50 consisting of various sensors perceiving a state of performance in each operating part in a car washing machine outputs a performance state sensing signal to a main board 46 on occasion. When the main board 46 judges the said signal is one that shows anything unusual, it outputs an emergency stop signal to a relay board 47 without delay. With this emergency signal, this relay board 47 immediately cuts off any feed to power to an output apparatus 48 of each operating part. And, simultaneously the main board 46 outputs such a signal as showing a trouble spot and a car washing process in time of trouble happening to a subboard 49 which, in turn, stores this signal in memory into a built-in random access memory and displays it on a display unit 30. Data being stored on top of that memory is optionally displayed on the display unit 30.
