Title: Manufacture of semiconductor device
Inventor: HASHIMOTO SHINGO
IPC: H01L21/316
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To prevent the leak current by forming means for isolating semiconductor elements by the selective oxidation method. SOLUTION: After removing a silicon oxide film 2 and silicon nitride film 3 on a semiconductor substrate 1 with leaving part of them in a specified pattern, a silicon oxide film 6 is formed. Side walls 9 are formed on the side faces of the nitride film 3, and the oxide film 6 is removed to expose the substrate 1, except its portions covered with the nitride film 3, thus forming an element isolating oxide film 7. This prevents the leak current.

IPC: G06F17/50
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a logic synthesis system capable of reducing manhours for preparing hardware description language(HDL) and manhours for repeating logic synthesis. SOLUTION: A logic synthesis function 1 executes logic synthesis for a new HDL 2 and outputs a synthetic network list 5.

Title: Overvoltage detection circuit
Inventor: HAYASHI TADATAKA
IPC: H02H3/05
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To inform of abnormality by forming operational test circuits at both ends of potential resistors which are connected to the neutral conductor of a cable line from a detection circuit, and if abnormality occurs, preventing a circuit breaker from shutting down when a test button is depressed. SOLUTION: An IC5 having a neutral conductor phase interruption detecting function makes a built-in switching element operate when input voltage exceeds a certain level. When the neutral conductor of a cable line 2 becomes in a phase-interrupted condition by some reason, and overvoltage exceeding a present value between L1-N or L2-N is generated, the input voltage of the IC5 increases, and the switching element is operated to energize a trip coil 4B. An overvoltage detection part 6 consists of an overvoltage detection lead wire 6A, a voltage divider resistor 6B, and a voltage divider resistor 8. An operational test circuit 7 consists of a switch 7A and a voltage divider resistor 7B. If no abnormality is in the overvoltage detection part 6, the IC5 comes into action when the switch 7A is closed in the same way as for generation of overvoltage.

Abstract: PURPOSE:To contrive to stop a motor of a sewing machine immediately upon the generation of an abnormality signal and make a sewing operation safe and secure, by providing a discriminating circuit which generates an abnormality signal in association with a concurrent generation of both an upper needle position signal and a lower needle position signal, in ghe case where a needle position detecting means is broken. CONSTITUTION:In the case where the generation of the upper position signal from a position detecting part P1 is not followed by the generation of the lower position signal from a position detecting part P2 and where the upper position signal is generated again after one cycle of a main spindle, a flip-flop F2 is not reset by a lower position signal, its Q terminal hols H and its Q' terminal hols L. Therfore, counters CT1, CT2 continues counting, while a counter CT2 becomes H, and at the trailing edge of the upper position signal, gate contions become G2=L, G4=H, G5=L and G6=H, thereby braking is actuated. In the case where the upper position signal is generated repreatedly and a lowe position signal is generated in such condition, the coexistence of both H signals results in that G9=L, a flip-flip F3 is set, Q'=L, G6=H and the motor is braked.
