Filed: 1983-02-03
Abstract: PURPOSE:To deliver a reset signal even with an instantaneous service interruption by connecting the middle point between a capacitor and a resistance connected between the stabilized voltages of a series stabilizing circuit to the middle point between a resistance and a constant voltage element connected between non-stabilized voltages via a diode. CONSTITUTION:The DC voltage (c) supplied to terminals 1 and 2 is stabilized by a series regulator 3 and supplied to a load 10. In this case, the middle point (a) between a capacitor 5 and a resistance 4 connected between stabilized voltages (d) is connected to the middle point (b) between a resistance 12 and a constant voltage element 11 connected between non-stabilized voltages (c) via a diode 13.

Title: Method and device for light wavelength conversion
Inventor: WAKAO KIYOHIDE
IPC: H01S5/042
Filed: 1990-01-26
Abstract: PURPOSE:To shorten the rising time and to speed up the waveform converting operation by making signal light incident on a semiconductor laser, and then decreasing the gain of laser oscillation with 1st oscillation wavelength and causing laser oscillation with 2nd oscillation wavelength. CONSTITUTION:The signal light is made incident on a semiconductor laser 20 which oscillates with the 1st oscillation wavelength by being supplied with a current under conditions where a hole burning phenomenon occurs, and then the gain of the laser oscillation with the 1st oscillation wavelength is decreased to cause the laser oscillation with the 2nd oscillation wavelength.

Abstract: PURPOSE:To reduce cell node potential fluctuations due to source voltage fluctuations and to reduce the deterioration of the soft error resistance by providing a specified potential generating circuit and specifying the cell plate potential of a memory cell having one transistor and one capacitor. CONSTITUTION:The potential producing circuit is formed by m-stage diodes D1-Dm, a memory cell transfer transistor and a series resistor R at the side of the ground Vss or the source Vcc depending on (n) channels and (p) channels.

When the operation state of an engine is judged to be in the partial load area, the opening timing and closing timing of an exhaust valve 6 and the opening timing and closing timing of an intake valve 5 in the high-engine speed, high-load area are concurrently changed to the spark delay side. The length of the overlap period from the opening timing of the intake valve 5 to the closing timing of the exhaust valve 6 in the valve timing adjusted to the spark delay side in the partial load area is almost the same as the basic valve overlap quantity, this period is set behind the top dead center, and the spitting from an exhaust passage 4 to an intake passage 3 can be suppressed.

Abstract: PURPOSE:To manufacture a dull roll excellent in wear resistance through minimum number of stages by forming a thick autogenous alloy layer on the surface of the roll, then, dull-working it with high density energy beam. CONSTITUTION:The surface of the base material 1 of the roll is roughed by shot blasting, etc., then, the autogenous alloy 2 is formed by thermal spraying on the uniformly preheated surface of the base material of the roll.
