Title: Synchronizing system
Inventor: KAGE GOZO
IPC: H04L7/00
Filed: 1984-12-26
Abstract: PURPOSE:To set reception and transmission clocks to a constact phase relation even when a clock is not received and to shorten the time required for synchroni zation by measuring a phase difference between the reception clock received by the 1st station and the 1st transmission clock. CONSTITUTION:Stations A and B are provided with the same constitution, and comprise the digital signal transmission system of a simplex system. A counter 19 at the station A side outputs the transmission clock TCLKA, which controls an A/D converter, and a transmitter 4 transmits a digital signal to the station B. A receiver 7 receives the signal from the station B, and a clock reproducing circuit 13 generates a clock RCLKA synchronous with the reception signal. A measuring circuit 16 measures the phase relation between the RCLKA and the TCLKA at the transmission side, and on the basis of this measured result a control part 15 decides the phase of the output TCLKA' of a variable delay circuit 14. The phase of the output TCLKA' is equal to that of the received digital signal, thereby shortening the time necessary for synchronization.

Title: Automatic setting method for optimum condition of recording/reproducing system
Inventor: KONO KATSUMI
IPC: G11B5/027
Filed: 1992-10-13
Abstract: PURPOSE:To perform recording/reproduce under the optimum conditions at all times by measuring the optimum concitions of a recording/reproducing system including a head and a tape of a video tape recorder while the recorder is atill and setting the optimum conditions.

Title: Cleanerless image forming device
Inventor: KAWAI HIDEAKI
IPC: G03G21/16
Filed: 1992-10-13
Abstract: PURPOSE:To decrease the uneven rotation of a photosensitive drum and to make the quality of a transferred image on recording paper high by providing a load application means which adds load torque to the photosensitive drum between a device frame and the photosensitive drum. CONSTITUTION:Coil springs 7 functioning as load torque application means are respectively supported in grooves 6a formed at both end parts 6 of the photosensitive drum 3. When a motor coupled with a supporting shaft 4 through a gear is driven, the drum 3 is rotated with the driving of the motor. At such a time, the pressing force of the coil springs 7 arranged on both end sides of the drum 3 becomes the load torque resisting the rotation of the drum 3 and is added to the drum 3. Therefore, the drum 3 is rotated more stably than the case that the load torque from the coil spring 7 is not added. By adding the proper load torque to the drum 3, the uneven rotation of the drum 3 is decreased.

IPC: F02M59/46
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To ensure valve opening operation of a check valve and preventing high pressure from acting on an electromagnetic valve for improving reliability. SOLUTION: Plungers 21 are arranged in a plurality of sliding holes 2 to apply pressure to fuel in a pressure chamber 23 to be forcibly fed with the reciprocation of the plungers 21.

A freezing action is advanced from an upper part to a lower part of the ice making pan 33 in one direction. A freezing speed is gradually delayed, thereby gaseous substance or various impurities in the water are discharged into non-freezed water. Even in case that a water supplying tank 53 is removed by a user during an ice making cycle, the non-freezed water is dropped into a water discharging pan 58 and then the water is disposed latter by the user or naturally evaporated within the refrigerating chamber 27.
