Title: Direct-current power supply
Inventor: TSURUYA MAMORU
IPC: H02M7/12
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent malfunctions due to high-frequency currents and high-frequency voltages produced on the alternating current input side without degrading the alternating current-to-direct current conversion efficiency of a direct-current power supply. SOLUTION: High-frequency components in a frequency band of 1-2 kHz contained in alternating-current input current IAC from an alternating-current generator 3 are extracted through a band-pass filter circuit 24. A product signal VN obtained from an alternating-current input voltage VAC from the alternating- current generator 3 and a detection signal VD from an error amplifier 22, outputted from a multiplying circuit 23 is compared with a detection signal V2 from an input current detector 19 at a comparator 25. The resultant comparison output signal VP is inputted, together with an output signal VB from the band-pass filter circuit 24, to a subtracting circuit 27. According to a difference signal VDF from the subtracting circuit 27, MOS-FET's 11 and 12 are on/off- controlled. Thus, malfunctions due to high-frequency current IN and high-frequency voltage VN produced on the alternating current input side can be prevented without degrading the alternating current-to-direct current conversion efficiency of a direct-current power supply 4.

Inventor: SATO KEIGO
IPC: H02P9/06
Filed: 1984-12-27
Abstract: PURPOSE:To obtain a trouble detection method for a rotation sensor of a shaft generator which enables continuous monitoring, by comparing the detection value of the rotation sensor with the relation of revolutions primarily determined among rotary elements. CONSTITUTION:Rotation sensors S1, S2 and S4 are provided to detect the revolutions of three rotary elements that is a sun gear 1, an internal gear 2 and a planetary carrier 4. Detection signals from the respective rotation sensors are inputted into an arithmetic processor 15 made up of a microcomputer or the like to calculate revolutions N1, N2 and N4 counting the number of pulses while any of the rotation sensors output a correct value, from which both are normal, if the relation of the following formula holds: (rho+1)N4=N1+rho.N2, wherein rho=constant. Otherwise, it is judged that at least any one the rotation sensors breaks down. Then, a signal indicating a trouble is outputted to a display 16 from the arithmetic processor 15 to give a warning by a display or an alarm.

Patent JP-H02126079-A (JP)
Title: Refrigerator
Inventor: UJI YUTAKA
IPC: F25D17/08
Filed: 1988-11-07
Abstract: PURPOSE:To ensure a steady cabinet interior temperature control by disposing a screen adjacent to the side of a flap and a cold air discharge opening respectively directed to the upper and lower parts of the refrigerated compartment from the side of the screen and above the lower end of it so as to prevent the condensation or icing on or near to the flap. CONSTITUTION:A control panel 15 houses in it a damper thermostat 18 comprising a flap 16 and an arm 17. Cold air is routed from the refrigerated compartment through a duct 19, and on to the upper part of the refrigerated compartment through a cold air inlet 20 out of an outlet 21 and also to the lower part of the refrigerated compartment from an outlet 22 through a discharge duct 23 in the control panel. A screen 24 is positioned such that its lower end is located below any of the outlets 21, 22. By this constitution, if a moist load is stored in the refrigerated compartment under the low outside temperature which tends to cause the flap 16 to fully close, the warm air rising from the discharge air duct 23 to the outlet 22 is blocked its convection near to the flap by the screen 24. It instead circulates by convection to the outlet 21, resulting in little chance of condensation or icing near the flap.
