Title: Semiconductor device
Inventor: KASHIMA MASAHITO
IPC: H01L29/06
Filed: 1988-12-22
Abstract: PURPOSE:To prevent a junction breakdown strength from being deteriorated when a wiring part of a high voltage is installed on a field plate by a method wherein the field plate having a potential gradient is installed on a P-N junction to which a reverse voltage is applied. CONSTITUTION:A polycrystalline Si film as a semiconductor film is used for a field plate 8; an end part 81, of a semiconductor substrate, on a P-layer 1 of the polycrystalline Si film 8 is doped with acceptor impurities 11; an end part 82 situated on an N-layer 2 of the film 8 is doped with donor impurities 12. A P-I-N junction is formed in the plate 6 in this manner; the end part 81 and the layer 1 are made equipotential; the end part 82 and the layer 2 are made equipotentiaI. Thereby, when a wiring part 10 of a high voltage is formed on the plate 8 via an interlayer insulating film 9, a sharp curve is not generated in a depletion-layer interface by an influence of the wiring part 10; it is possible to prevent an N-layer from being formed near an interface between the layer 2 and an oxide film 5. Accordingly, it is possible to prevent a junction breakdown strength from being deteriorated.

Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To shorten time to be required from the active state of an interruption signal outputted from a peripheral unit up to the start of practical processing based on an interruption processing program. SOLUTION: An interruption processing base address pointer(IBAP) 8 is included in a peripheral unit 7 and a central processing unit(CPU) 1 reads out the IBAP simultaneously with the reading of a vector address from an interruption controller(INTC) 5, adds the value of the IBAP to the value of a program counter(PC') read out from a register bank 4 and writes the added value in a PC 2 built in the CPU 1 itself. Since an address indicated by 'PC+IBAP' is the leading address of a program for executing original interruption processing, the prescribed interruption processing can be immediately started.

Title: Tuner
Inventor: YAMAZAKI DAISUKE
IPC: H03J3/28
Filed: 1990-11-27
Abstract: PURPOSE:To utilize the tuner as the variable capacity required for tuning and oscillation by applying a receiving input signal and an oscillating signal by varying its levels, respectively by a variable gain amplifier, to both ends of each capacitor of the fixed capacity for determining a tuning frequency and an oscillation frequency, respectively. CONSTITUTION:Two capacitors C3, C4 of the fixed capacity for determining a tuning frequency and n oscillation frequency, respectively are prodded. In such a state, by varying a voltage (signal) level applied across these capacitors C3 (C4) by a variable gain amplifier 7 (8), charge which can be accumulated in the capacitors C3 (C4) comes to variable. This fact is equivalent to a fact that a capacity value of the capacitors C3 (C4) is variable, and the capacity comes to variable continuously, virtually by the gain control of the variable gain amplifiers 7 (8). In such a way, this tuner can be utilized as the variable capacity required for tuning and oscillation instead of a variable condenser and a variable capacitor.
