Filed: 1977-10-18
Abstract: PURPOSE:To make operation high-speed and reduce power consumption by controlling the power source for a fixed memory unit by a retriggerable monostable multivibrator in the information processing. CONSTITUTION:When upper address signals 7A to 7M are applied to block decoder 5, one of fixed memory unit selection lines 6A to 6N is activated to trigger a corresponding one of retriggerable monostable multivibrators 8A to 8N, and one, which corresponds to the output, of power source switches 4A to 4N is turned ON to activate a corresponding one of fixed memory units 1A to 1N.

Title: Optical switch
Inventor: WAKAO KIYOHIDE
IPC: G02F1/313
Filed: 1989-05-20
Abstract: PURPOSE:To change the coupling length of a waveguide and to reduce a crosstalk with a simple means by providing electrodes at the external sides of a core layer and the waveguide formed in its vicinity and making a current to flow to the electrodes. CONSTITUTION:A groove 14A is formed in an InP clad layer 14 formed on an InGaAsP core layer 13. Electrodes 16 and 17 are formed through an InP contact layer 15 at the external sides of the groove 14A and optical waveguides G1 and G2 formed in its vicinity. Thus, when a current is made to flow to the electrodes 16 and 17, a refractive index just under it is lowered, the coupling length of the waveguides G1 and G2 is changed, and the distribution ratio of output lights P1 and P2 is changed. Consequently, by setting the supplying electric current I1 and I2 at proper values, all input lights P0 is shifted to the waveguide G2, and the crosstalk can be easily reduced.

Title: Combustion controller in evaporation burner
Inventor: MIYAHARA KINGO
IPC: F23D11/02
Filed: 1978-10-12
Abstract: PURPOSE: To ensure stable combustion, by eliminating the floating, going-out, etc. of flames just after moving to evaporating combustion by sufficiently heating a combustion cylinder at high temperatures during the time up to an evaporating combustion condition from a raw combustion condition by temporarily increasing the quantity of combustion after igniting a burner.  
     CONSTITUTION: A temperature sensing switch 16 mounted to an outer wall of a combustion cylinder 1 is not worked until the combustion cylinder 1 reaches temperatures that evaporating gas is not liquefied, the temperature sensing switch 16 remains as it closes, a combustion air increasing valve 18 is kept in wide opening and a feed fuel oil increasing valve 28 under an opening condition during the time and air and fuel oil more than the quantity of air burnt and the quantity of fuel oil fed under a stationary combustion condition are supplied into a rotary evaporating cylinder 6. Consequently, the combustion cylinder 1 is rapidly heated because the quantity of raw combustion in the combustion cylinder 1 is much. Thus, the floating and partial going-out of flames resulting from the cooling and liquefaction of the evaporating gas never be produced because the combustion cylinder 1 previously reaches the temperatures that the evaporating gas is not cooled and liquefied even after moving to an evaporating combustion condition from a raw combustion condition.

Filed: 1994-05-16
Abstract: PURPOSE:To prevent a transistor(TR) at an output stage of a high efficiency amplifier circuit from being in excess of its break-down strength. CONSTITUTION:The collector potential of a TR Qa of the output stage changes in following to an input signal waveform thereby keeping a collector-emitter voltage VQa of the TR Qa low thereby reducing the loss. A high level peak hold circuit 53 holds the peak of the collector potential of the TR Qa when a high level input is received. An amplitude limit means 14 prevents the break- down strength from being exceeded by limiting the amplitude of the input when the voltage VQa of the TR Qa is going to be excess in of its break-out strength by the high level peak hold operation.
