Patent JP-S60109262-A (JP)
Title: Manufacture of semiconductor device
Inventor: HIRASHIMA TOSHINORI
IPC: H01L27/092
Filed: 1983-11-18
Abstract: PURPOSE:To reduce the number of processes of manufacturing a bi-polar CMOS- IC by simplifying the process without the use of a CVD oxide film and the like by a method wherein a nitride film and an isolation oxide film are both used as a diffusion mask. CONSTITUTION:The nitride mask 3 with an oxide film 2 as its base is formed on a semiconductor Si substrate 1. A thick field oxide film 2a is formed at the part without the mask by field oxidation unde conditions of high temperature and high moisture. Boron is ion-implanted to the substrate surface in the state of removal of the oxide film 2 on the substrate surface. A P type base region 15 is formed by thermal diffusion of boron into the substrate. Even when the nitride used as the mask at the time of local oxidation is base-diffused, it can be utilized as the mask it is; therefore, the number of processes can be reduced. A CVD-SiO2 mask becomes unnecessitated, and a defect due to pin holes does not occur, resulting in improvement of the reliability and the yield of semiconductor products.

Title: Focusing detector
Inventor: OOTAKA KEIJI
IPC: G02B7/36
Filed: 1982-12-10
Abstract: PURPOSE:To maintain high accuracy while maintaining the pitch of photodetectors within the range where the production thereof is easy by providing plural systems of photodetector arrays disposed with a deviation by a prescribed quantity of the element arrays from each other in the array direction of the photodetectors. CONSTITUTION:If the out-of-focus image 6 of a slit image having a negligible width is projected on photodetector arrays, focusing is judged on the photodetector array 5-1 but the luminous flux is made incident to two photodetectors 7-1, 7-2 on the photodetecor array 5-2 and therefore an out-of-focus is detected. Plural systems of photodetector arrays are used in such a way and the state where all the outputs from the arrays are focused is judged to be a focusing point, whereby the accuracy in detecting the focusing is improved without increasing the pitch of the photodetector arrays.

Title: Level converting circuit
Inventor: TOKIDA KENSUKE
IPC: H03K19/018
Filed: 1982-12-13
Abstract: PURPOSE:To attain high speed operation by making the logical amplitude of a level converting output optimum. CONSTITUTION:Since a diode D1 or D2 is turned on with an input signal at an input terminal IN1 or IN2 set to an L level, a transistor (TR) Q11 is turned on and a TRQ10 is turned off. Thus, A current I2 of a constant current source I2 flows to the TRQ11 side and a current I1 of a constant current source I1 flows to a resistor R10 and a level shift diode. Then, when the input signal at the terminals IN1 and IN2 is both at H level, since the diodes D1, D2 are both at off-state, the TRQ10 is brought into on-state and the TRQ11 is brought into off- state. Thus the current I2 flows to the resistor R10 through the TRQ10. The logical amplitude value possible for high speed operation is attained by selecting suitably the resistance value of the resistor R10, the level shift amount and the current value of the current I1, I2 in the operation above.

Title: Remote controlled circuit breaker
Inventor: IKEDA TATSUNORI
IPC: H01H75/02
Filed: 1990-08-18
Abstract: PURPOSE:To construct a remotely controlled circuit breaker compactly and accomplish remote control and high sped opening of the contact by opening the contact at a high speed when an overcurrent flows, and actuating a control mechanism part when overcurrent is sensed. CONSTITUTION:A handle 43 is turned in the auto position to put free a contact lever 55 and a maglink 53, through which contacts 5, 7, 8, 12 are opened and closed. When an overcurrent, flows, an overcurrent trip part 500 trips a control mechanism part 400 regardless of the maglink 53 coupled with a solenoid arrangement 300, and a push plate 51 rises to rotate the contact lever 55, and thus the contacts 5, 7, 8, 12 are opened at a high speed. Thereby a circuit breaker is embodied compactly in a single piece construction, and high frequency opening/closing performance with long lifetime is obtained by the solenoid arrangement 300 in remote control system, which can be separated by the control mechanism part 400. Thus high speed breaking performance is achieved by the overcurrent trip part 500, and the contacts are prevented from fusion attachment and exhaustion.
