Title: Fallout preventing structure for motor shaft
Inventor: SAITO KATSUZO
IPC: H02K5/16
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To provide the fallout preventing structure for motor shaft without generating the flow loss of the oil and the contamination with the foreign matter while preventing the lowering of the rotary torque to be generated even in the case of miniaturization and reduction of thickness by removing a ring-like barrel part engaged with the inside of a locking groove and engaged with a motor shaft from an outside fixation part. SOLUTION: A fallout preventing member WO for shaft is arranged so as to be fixed by a radial bearing Br between a bottom part of the radial bearing Br and a motor housing H. An outside fixing piece of the fallout preventing member WO for shaft and a ring-like barrel part are connected to each other through at least one connection part. When a shaft S is pushed, the fallout preventing member WO for shaft is separated at a weak part of the connection part, especially at a connection part to the ring-like barrel part, and the only ring-like barrel part is engaged with the motor shaft S. As a result, intrusion of the shaft S in the radial bearing Br direction can be hindered, and fallout of the shaft can be prevented.

Title: Integrated circuit device
Inventor: FUJII YASUHIRO
IPC: H03K5/135
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce the time till locking in the case of resetting while suppressing power consumption after locking. SOLUTION: A phase comparator circuit 8 that compares the phase of a reference clock frequency-divided by a frequency divider 4 which frequency-divides a supplied clock with the phase of a variable clock generates a phase synchronization detection signal upon the detection of coincidence of the phases of both the clocks, the phase synchronization detection signal increases a frequency division ratio of the frequency divider 4 to decrease the frequency of operation of the phase comparator circuit 8.  In the case of resetting denoting a state change from an inactive state into an active state, the phase synchronization detection signal is reset to restore an original state, a lower state of a frequency division ratio of the frequency divider 4 to set the frequency of operation of the phase comparator circuit 8 to the original high frequency thereby reducing a time required up to phase synchronization of both the clock signals. Thus, when phase synchronization is detected in the active state, the frequency division ratio of the frequency divider 4 is set higher to decrease the frequency of operation of the phase comparator 8 thereby reducing the power consumption.  In the case of resetting state, the phase synchronization detection signal is reset to set the frequency division ratio of the frequency divider 4 to the original lower state thereby increasing the frequency of phase comparison.

Title: Kerosene-vaporizing burner
Inventor: YAMAZAKI YASUSHI
IPC: F23D11/44
Filed: 1990-10-24
Abstract: PURPOSE:To prevent kerosene from being vaporized at the same time that kerosene enters a vaporizer even in the case where the amount of kerosene supplied is small by providing heat radiating fins on a fuel feed pipe, which is apt to be heated, in the vicinity of the kerosene vaporizer. CONSTITUTION:A fuel feed pipe 20 is heated by heat generated by a vaporizer 30 in the vicinity of the vaporizer during the operation of combustion. Especially, in the case where a kerosene input (the amount of kerosene supplied) by an electromagnetic oil pump 10 is small, the flow rate of kerosene passing through the fuel feed pipe 20 is small; therefore, kerosene in the fuel feed pipe 20 is heated up to a considerably high temperature just before entering the vaporizer 30. Accordingly, heat radiating fins 70 are provided on the fuel feed pipe 20 in the vicinity of the vaporizer 30 and, by cooling the heat radiating fins 70 with cooling air introduced through an air inlet port 80 provided on the side wall of a combustion chamber 3, heat of the fuel feed pipe 20 is rapidly radiated via the heat radiating fins 70, and a temperature rise at the fuel feed pipe 20 can be prevented. Therefore, kerosene that has entered the vaporizer 30 is not instantly vaporized.
