Title: Power source circuit for driving liquid crystal
Inventor: IMURA KOJI
IPC: G09G3/36
Filed: 1990-02-23
Abstract: PURPOSE:To reduce an electric current consumption by providing an impedance converting circuit so that the required current flows only while moving pictures are displayed. CONSTITUTION:Plural 1st switching means 15 to 17 respectively connect plural resistors 10 to 13 and the connecting points A to D of the plural resistors 10 to 13 when the signal voltage impressed to a liquid crystal is in a stationary state and plural output terminals VA, VM, VB, VDisp. These means shut off the connection between the connecting points A to D of the plural resistors 10 to 13 and the plural output terminals VA, VM, VB, VDisp when the signal voltage is in a transient state. Plural 2nd switching means 36, 37, 43, 44 respectively connect the impedance converting circuit and the plural output terminals VA, VM, VB, VDisp when the signal voltage is in the transient state and shut off the connection between the impedance converting circuit and the plural output terminals VA, VM, VB, VDisp when the signal voltage is in the stationary state. The flow of an excessive current is obviated while the static images are displayed in this way and, therefore, the current consumption is reduced.

IPC: F25B1/00
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To keep temperature within a space desired to control temperature of a thermostat or the like at a value as set by a user. SOLUTION: A heat exchanger 7 performs a heat exchange between a refrigerant at a low temperature liquefied by a capacitor 11 and a high temperature/ high pressure refrigerant to be outputted from the high pressure side of a refrigerating machine 9. After the heat exchange, the two refrigerants are guided into an evaporator 2 through pipes 75-1 and 75-2, a convergent part A and the like. A solenoid valve 6 mounted on the pipe 75-2 regulates a flow rate of a refrigerant (the refrigerant liquefied by the capacitor 11) following the heat exchange as flowing out of the heat exchanger 7 according the control by a temperature control part 4.  Thus, the solenoid valve 6 is controlled based on a difference between temperature in the thermostat 1 detected by a temperature sensor 3 and a temperature set by a user to regulate the flow rate of the refrigerant flowing out of the heat exchanger 7, thereby keeping the temperature in the thermostat 1 at a set value.

Title: Separately ventilated direct current machine
Inventor: HIRAYAMA TAKEHIKO
IPC: H02K9/02
Filed: 1979-04-13
Abstract: PURPOSE:To decrease a draft resistance loss and, at the same time, to improve the cooling effect  on the side of a stator by performing a director draft with a part of feed-air directly inducted into  the cavity section between the main pole and the auxiliary pole of a stator. CONSTITUTION:Cooling air is divided into two parts, one of which is passed inside a rotor 1 as  shown by arrows and the other is sent from the exterior circumference of the stator frame core  11, pass through an air guide opening 15 and comes to the cavity 14 located between the main  pole and the auxiliary pole. Therefore, the air flow passing through the side of the rotor 1 is decreased, thereby decreasing the draft resistance loss. On the other hand, in case when the air  guide opening 15 is not provided with the cavity 14, the wind speed is very small and the draft  resistance loss is small as compared with the gap 7 between the rotor 1 and the main pole core 10 and the gap 8 between the rotor 1 and the auxiliary pole core, so even the air flow is increased by  providing the air guide opening 15, the total draft resistance loss will be small. Also the decrease in the cooling effect is not recognized at the rotor section, but as the temperature of the coils 12  and 13 of the main pole and the auxiliary pole decreases to a great extent, the cooling effect is greatly increased synthetically. Therefore, the cooling effect can be increased with a small draft  resistance loss.
