Title: Refrigerator and control method therefor
Inventor: TSUKAMOTO KEIZO
IPC: F25D29/00
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To cool refrigerating and freezing sections individually by supplying all refrigerant to a refrigeration evaporator at the time of cooling the refrigerating chamber and supplying all refrigerant to a freezing chamber at the time of cooling the freezing chamber even if a valve for switching a refrigerant channel leaks. SOLUTION: Throttling of a refrigeration capillary tube 70 is set looser than that of a freezing capillary tube 72. If the freezing capillary tube 72 side coupled with a freezing evaporator 52 leaks when a refrigerant channel is switched to a channel coupled with a refrigerating evaporator 50 by means of a three-way valve 68 in order to cool the refrigerating chamber, refrigerant does not flow smoothly to the freezing capillary tube 72 side but flows smoothly to the refrigerating evaporator 50 side because the freezing capillary tube 72 is throttled more than the refrigeration capillary tube 70.

Title: Fuel injection amount limiting device for hydraulic governor
Inventor: TANIGUCHI HIROYUKI
IPC: F02D1/02
Filed: 1989-07-14
Abstract: PURPOSE:To prevent generation of black smoke and surging of an exhaust turbine by providing the rotary fulcrum shaft for an output lever with location changeability in the direction where the lever ratio of the output lever can be changed, and interlocking this rotary fulcrum shaft with a speed control lever through a fulcrum shaft location changing mechanism. CONSTITUTION:When a speed control lever 47 is turned for ex. in the direction of decreasing the speed, a fulcrum shaft location change lever 72 is rotated in the K1 direction round a fixed shaft 71 through an eccentric pin 75 and an eccentric lever 78 of a speed control shaft 46, and thereby the fulcrum shaft 67 is elevated to lessen the lever ratio X/Y of a lever 60. Thereby the fulcrum shaft 67 is moved to the side where the incremental amount of fuel injection according to the rotating amount of a terminal shaft 43 lessens. If therefore an overload is applied when setting is made in the slow condition (partially loaded) on the deceleration side, the incremental amount of the fuel injection with respect to the rotating amount of the terminal shaft 43 lessens and also the max. limit fuel injection amount becomes smaller, and no excessive increase will be made even though the fuel is increased when load is applied abruptly, which should prevent generation of black smoke.

Title: Sine wave/rectangular wave conversion circuit
Inventor: MIYABAYASHI YUKIMASA
IPC: H03K12/00
Filed: 1990-07-10
Abstract: PURPOSE:To enable operations with one power source by connecting a low- resistance pull-down resistor to the point of connecting the cathodes of both input side and output side diodes, connecting a high-resistance pull-up resistor to the anode of the output diode, defining the anode of the input side diode as an input terminal and defining the anode of the output side diode as an output terminal. CONSTITUTION:When an input signal is a high positive voltage higher than a power supply voltage (+V), the input voltage is blocked since a reversed voltage is applied to an output side diode D2, and the voltage (+V) connected by a pull-up resistor R2 is outputted as an output signal. Reversely when the input signal is a negative voltage, the reversed voltage is applied to an input side diode D1 and the input voltage is blocked. On the other hand, a forward voltage is applied through the pull-up resistor R2 and a pull-down resistor R1 to the output side diode D2 and as an output signal, a voltage divided by the pull-up resistor R2 and the pull-down resistor R1 is outputted. In this case, since the pull-up resistor R2 is of adequate high resistance in comparison with the pull-down resistor R1, 0V is nearly outputted. Thus, operations are enabled with one power source.
