Abstract: PURPOSE:To miniaturize the titled circuit by connecting a capacitor in series with a snubber circuit connected in parallel with a switch with a drive terminal and using the charging voltage of the capacitor for a power supply of a switch drive circuit so as not to eliminate the need for a drive power supply separately. CONSTITUTION:The snubber circuit 3 comprising a resistor 31, a capacitor 32 and a diode 33 is connected in parallel with a switch 1 comprising a gate turn-off thyristor 11 and an FET 12 and a capacitor 41 of a power supply circuit 4 is charged by a main circuit power supply via the snubber circuit 3 when the switch 1 is turned off. The charging voltage of the capacitor 41 is brought into a constant voltage by a Zener diode 43 and fed to a power supply of the drive circuit 2. Further, when the switch 1 is turned on, although the electric charge in the capacitor 32 is discharged via the switch 1 and the diodes 5, 6, the discharge of the electric charge in the capacitor 41 is blocked by a diode 42. Thus, it is not required to provide especially the power supply of the drive circuit 2 and the circuit is miniaturized.

Title: Air conditioner
Inventor: YOKOYAMA HIDENORI
IPC: F24F11/02
Filed: 1983-04-08
Abstract: PURPOSE:To prevent a rise in room temperature upon restarting and to allow an efficient operation with a high dehumidifying efficiency by rapidly increasing the rotational speed of a compressor upon restarting and slowing down the compressor speed after cooling an evaporator. CONSTITUTION:The rotational speed of a compressor is made slower than the normal cooling mode,and a room unit fan is also operated at a slower speed. Then, the room temperature is reduced eventually to a temperature set by a temperature controller when the intermittent operation mode is assumed. At this time, a high speed operation is carried out upon starting during which a room unit fan is stopped. After an evaporator is fully cooled down, the compressor speed is lowered and the room unit fan is operated. Since the compressor operates at a high speed upon starting up, the evaporator is rapidly cooled, and by operating the room unit fan thereafter, the revaporation of water on the surface of the evaporator can be prevented.

Filed: 1991-02-07
Abstract: PURPOSE:To double the data transfer rate by giving a bias magnetic field of an overwrite medium of a precedent auxiliary magnetic field exchange coupling film by means of a sheetlike magnet stuck to a substrate. CONSTITUTION:Two PC substrates fitted with a magnetic layer respectively are stuck to a plastic sheet magnet 7 by adhesive layers 8 and 9. Then, magnets 11 and 12 for giving precedent auxiliary magnetic fields are disposed in pair in symmetrical positions as against a center of a disk 10. That is, the precedent auxiliary magnetic fields 11 and 12 are set in a position of 90 degrees clockwise and a position of 90 degrees counterclockwise from the positions of optical heads 13 and 14 respectively. Since the bias magnet is incorporated into the medium in this recording and reproducing device, and hence because of no need of the bias magnetic field for drive, the heads 13 and 14 can be arranged opposite to each other. By this method, simultaneous access to both sides is facilitated, and the data transfer rate can thus be doubled.
