Title: Power supply apparatus
Inventor: UESUGI SHIGENORI
IPC: H02M3/155
Filed: 1984-08-28
Abstract: PURPOSE:To reduce the calorific value and electric consumption of a circuit for supplying a control circuit with power source, by a method wherein a condenser is charged according to constant voltage generated from a constant- voltage generation circuit, and wherein while a switching element is ON, the control circuit is supplied with power source through the charged condenser. CONSTITUTION:When a transistor (TR)2 is OFF, input voltage is applied to a series regulator through a parallel circuit with diode D2, choke coil L, resistance R3, and load, and a control circuit 1 is supplied with power source through TR1 and the resistance R2, and a condenser C2 is charged. In the meantime, when TR2 is ON, the series regulator is short-circuited by the TR2, and so the TR1 is turned OFF and the control circuit 1 is supplied with voltage between the terminals through the condenser C2. Accordingly, only when the TR2 is OFF in the series regulator, then electric current flows to constant- voltage diode ZD through resistance R1, and while the TR2 is ON, current does not flow to the constant-voltage diode ZD.

Abstract: PURPOSE:To select properly a high-speed bus or an extended high-speed bus and  to realize a connection between computers, by using a switch device that sets  an effective state for either one of a high-speed bus interface circuit and an extended high-speed bus interface circuit. CONSTITUTION:A bus selection signal J is set to an HB side by a switch circuit 30 that can switch and set manually the logic of the signal J to the side of a high-speed bus HB or an extended high-speed bus EHB. Thus interface circuits 20, 22 and 24 of the bus HB plus a control circuit 28 are made active. While the interface to the bus EHB plus a control circuit are set inactive. The interface circuits 22, 23, etc. can always be set to the reciprocal active state by an output gate. In such way, the buses HB and EHB can be properly selected and connected via the circuit 30. As a result, an extending adaptor which is required for a composite computer system can be eliminated. Furthermore a selective connection is possible to the buses HB and EHB since the active state can be properly switched and set for the interface circuit and the control circuit by means of the signal J.

Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a failure even when resetting operation is erroneously performed (a reset button is pressed) by performing a system stopping process and preserving necessary information. SOLUTION: When a reset button 11 is pressed, the software of a computer receives system resetting information 31 and performs a system stopping process (T5) and stops software processing by turning off a reset inhibit flag 13. When the flag 13 is turned off, a system-reset signal 26 is outputted to reset the computer. On the other hand, a forcible reset timer 12 constituted of hardware is set at time longer than the time required for performing the system stopping process and, when the reset button 11 is pressed, the timer is started. When the above-mentioned set time has elapsed, system resetting is executed by outputting the reset signal 26 regardless of whether or not the system stopping process is completed (the rest inhibiting flag 13 is turned on).

IPC: F25B43/00
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To increase the oil sucking force of an oil returning hole so as to increase the returning mount of oil to a compressor by bending a leading-out pipe provided in a container on the bottom side of the container and forming a recess which reduces the cross-sectional area of the pipe at the bent section, and then, forming the oil returning hole in the recess. SOLUTION: In the container 4 of an accumulator 1, a leading-in pipe 5 for leading in a refrigerant, a leading-out pipe 6 for discharging a gas, and a desiccating agent 8 are provided. The leading-out pipe 6 is bent in a U-shape on the bottom side of the container 4 and the front end of the pipe 6 has an opened introducing port 9 and positioned in the upper part of the container 4. A recess 10 is formed near the bottom section of the pipe 6 and an oil returning hole 11 is provided at the center of the recess 10. The recess 10 is formed by deforming the pipe 6 inward so as to reduce the cross-sectional area of the flow passage formed of the pipe 6. Consequently, the flow velocity of the refrigerant passing near by the recess 10 becomes faster and a Venturi effect occurs in the hole 11.  Therefore, the hole 11 sucks the oil accumulated in the lower part of the separated container 4 and a sufficient amount of oil is returned to a compressor even when the flow velocity is the lowest.
