Abstract: PURPOSE: To surely attain sufficient voltage boosting by providing a level conversion circuit shifting a level of a boosting power supply circuit up to its output level to the output buffer circuit and adopting the configuration eliminating the need for a pumping capacitor thereby decreasing an access time and suppressing increase in a mask size. CONSTITUTION: The output buffer circuit is made up of a boosting circuit 101, NAND ates 102, 103, a level conversion circuit 104, a PMOS transistor(TR) 105, an NMOS TR 106, an inverter 107, output TRs 108, 109 being NMOS TRs and an output terminal 110. Then an output of the level conversion circuit 104 shifting a level of an input signal up to a potential boosted by the boosting circuit 101 is applied to a gate of the output TR 105 connecting to a power supply side of the output buffer comprising the output TRs 108, 109 connected in cascade. Since the level conversion circuit 104 is configured not to employ a capacitor, no charging is required and the operating speed is improved.

Filed: 1990-09-03
Abstract: PURPOSE:To offer parts simple in structure and having a wide field distribution of exciting light and high amplification efficiency by connecting an optical fiber which has a larger core diameter to one of optical fibers connected to a joined part. CONSTITUTION:The optical fiber 15 is connected to the optical fiber 12 of a port D among ports A-D. This optical fiber 15 consists of a core part 15a and a clad part 15b and the core part 15a has a diameter larger than the core diameter of the core part 12a of the optical fiber 12.

Abstract: PURPOSE:To relieve the load of a processor side by providing a counter counting a carry signal of an adder to the adder, using this counter so as to obtain the result of accumulation, allowing to eliminate the processing giving a data to the adder. CONSTITUTION:When a processor CPU receives a request of accumulating processing from an input/output device I/O, a register R and a counter CT are cleared, a data (a) to be accumulated in digit (n) is applied to the adder AD, where the accumulated data (a) and a data (r) as the result of accumulation in the register R are added, and the result is stored in the register R. When a carry signal C is outputted from the adder AD, the counter CT is incremented by ''+1'' by this carry signal C. Similarly, the data (a) to be accumulated is applied to the adder AD and accumulated to the register R and the counter CT. When the processor CPU completes the supply of all the accumulated data to an accumulator T, a read signal is given to a selector S, which outputs the count value of the counter CT as the data in n-digit, and the value of the register R is applied to the processor CPU.

Filed: 1993-08-25
Abstract: PURPOSE:To obtain a heat radiating fin the heat radiating efficiency of which can be improved by ventilation and, at the same time, which can be easily manufactured. CONSTITUTION:A heat radiating fin is constituted of a plurality of platy fins 11 and a plurality of thin supports 12 which couple the fins 11 with each other at prescribed intervals. The fins 11 respectively have a plurality of holes at the same positions except the one 11a at the end and the thin supports 12 are respectively passed through the holes and fixed to the fins 11 in the holes. One end sections of the supports are connected to a semiconductor element 3 which is a heat generating component through a heat radiating fin mounting section 7. When air is made to flow through the space between respective fins 11, the air does not stagnate, but flows smoothly, due to the thin thicknesses of the support 12. Therefore, the cooling efficiency of the heat radiating fin can be improved by increasing the flow velocity of the air flow.
