Title: Oil/water separator
Inventor: NAKAYAMA KATSUO
IPC: B01D17/025
Filed: 1984-07-11
Abstract: PURPOSE:To recover only the oil content of a large quantity of waste water by feeding waste water in an upper tangent direction of a cylindrical water tank having an oil drain pipe provided in the center and a separator arranged. CONSTITUTION:Waste water 7 containing oil which flows in from an inlet 2 generates an eddy in a cylindrical water tank 1. The oil collects to the center of the cylindrical water tank 1 by the rotation of waste water and floats. If the floating oil collides the lower surface of a separator 4 from underneath, it floats along the lower surface of the separator 4 and is a float at the liquid level in the center of the cylindrical water tank 1. As an oil inlet 3A of an oil drain pipe 3 is positioned slightly lower than the liquid level in the center of the cylindrical water tank 1, the oil a float at the liquid level in the center of the cylindrical water tank 1 is drained through the oil drain pipe 3.

Title: Semiconductor laser and manufacture thereof
Inventor: HAMADA HIROYOSHI
IPC: H01S5/00
Filed: 1986-06-19
Abstract: PURPOSE:To obtain a semiconductor laser, cost of which is reduced, threshold currents of which are lowered and in which thermal strain, etc. arc not generated, by crystal-growing an insulating single crystal layer onto an silicon substrate and forming a resonance section at the central section of the insulating single crystal layer. CONSTITUTION:A resonance section 2 is shaped at the central section of the upper surface of an silicon substrate 1, buried layers 3 are formed on both sides of the resonance section 2 under the state in which the resonance section 2 is buried, and electrodes 4, 5 are shaped onto the lower surface of the substrate 1 and the upper surfaces of the resonance section 2 and the buried layers 3. Since an insulating single crystal layer is formed previously and the resonance section 2 is shaped to an insulating single crystal removing section at the center of the insulating single crystal layer, the resonance section is not heated at a high temperature when forming the buried layers as seen in conventional devices, thus reducing the possibility of the generation of thermal strain. The cost of the silicon substrate 1 is reduced and the effect of heat dissipation thereof is also improved, thus resulting in a large amount of advantages at cost and on a thermal countermeasure.

IPC: G06F1/30
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To obtain an uninterruptible power-supply apparatus by which the power supply of an information processor or the like can be turned on automatically without the intermediary of man power by providing a power-supply turning-on-signal output circuit which inputs a power-supply turning-on signal to a utilization device as long as a power-failure detection signal is stored in a storage means when a commercial AC power supply is restored. SOLUTION: The occurrence of a power failure is stored by a latching relay 18. When a commercial AC power supply is restored after that, a power-supply turning-on signal S3 instead of a power-supply turning-on switch 24 is input to a terminal device 2 by the AND condition of the storage signal of the latching relay 18 and of a signal indicating that the commercial AC power supply is restored, and the power supply of the terminal device 2 is turned on automatically. Consequently, when the commercial AC power supply is restored after the power failure, the power supply of the terminal device 2 can be turned on without the intermediary of man power. As a result, it is possible to prevent a drop in the operating ratio of the terminal device 2 due to a situation that an operator does not realize the restoration of the commercial AC power supply after the power failure.

Abstract: PURPOSE: To sense fault of a throttle override device by judging the throttle override device failure by comparing an initial value of an engine speed at the starting operation of a throttle override system and a current value after certain time of operation with the exception of the difference being larger than the standard value. CONSTITUTION: Corresponding to sensing requirement of transmission shift, a throttle override device 34 starts operation and an initial value ESo of an engine 16 speed is detected and stored. After a certain time TREF, the current value ESC of the engine 16 is detected.
