Abstract: PROBLEM TO BE SOLVED: To reduce the burrs of a wheel train bridge so as to reduce the frictional torque by forming a main plate and the bridge of plastic materials and one bearing member of the bearing section of a recessed groove and the other bearing member of the bearing section of a through hole, and then, supporting the front end of the shaft section of a plastic rotor with the bearing members without allowing the front end to be protruded from the bearing members. SOLUTION: A main plate 11 is formed of a plastic material and a plastic rotor 12 is formed by insert-molding a magnet 13. A fifth wheel and pinion 14 and a wheel train bridge 18 are formed of plastic materials and the lower shanks 12-1 and 14-c and upper shanks 12-b and 14-b of the rotor 12 and gear 14 are respectively put loosely in the holes 11-a and 11-b of the main plate 11 and the holes 20 and 18b of the bridge 18. The holes 20 and 18-b are formed in recessed grooves and the wall thickness of the front end of a shank for deciding the struggling of a wheel train is set at about 0.2-0.25mm so that the plastic material can be easily charged.  Therefore, no burr is generated on the periphery of the hole of the bridge 18 and the frictional area between the rotor 12 and gears becomes smaller, because the rotor 12 and gears are positioned in the axial direction at the front end of the shank.

Title: Control unit for vehicle
Inventor: HACHIMAN KOICHI
IPC: H01L25/18
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To protect electronic components from the temperature rise in a casing by providing a gelled material expansion preventive wall for preventing the expansion of gel substance disposed on a printed board and a frame which, being in contact with the gelled material, fixes the printed board. SOLUTION: This unit is constituted of a gelled material expansion preventive wall 4 disposed on a printed board 1 so as to prevent the expansion of the gelled material 5 covering electronic components 2, 3 disposed on an upper face of the printed board 1 and a frame 6 which, being in contact with the material 5, fixes the printed board 1. Even if the temperature in the casing exceeds an operation guaranteeing range for an IC 2, the IC2 can be kept near the cooling water temperature and thereby can be protected from the temperature rise in the casing since the generated heat is transmitted to the cooling water 12 through a high heat transmission path from the gel 5, then to the frame 6, to the casing 10 and finally to the cooling water 12. The gelled material expansion preventive wall 4 also prevents the leakage of the gel out of the board caused by the vibration of the vehicle.

This differential voltage is amplified and is outputted to a phase control circuit. The counter output passes an AND circuit 21 to become an operation condition of a keep relay circuit 22; and if power supply is cut off, a one shot circuit 25 generates a pulse by power break detection in a means 24, and the keep relay of the circuit 22 is operated in accordance with AND conditions between this pulse and the output of the counter 19. After power restoration, a preset signal is inputted to the counter 19 by the output of a circuit 26, and the counter output becomes in the same state as the operation of the circuit 22.

Title: Sound erasing device
Inventor: UEMURA HIDEO
IPC: H04N5/60
Filed: 1987-06-30
Abstract: PURPOSE:To omit the switching sound erasing pulse output terminal of a microprocessor and a switching transistor and to simplify a circuit constitution by providing a signal changing-over switch including a non-signal and a microprocessor having a control signal output terminal used as an external input switching signal and a switching sound erasing signal in common. CONSTITUTION:At the signal switching time of a broadcasting signal and an external input signal, from a control signal output terminal of a microprocessor 1, a control signal (the input switching signal of the broadcasting signal or of the external input signal) is sent out and a signal changing-over switch 3 is switched to A or B by this control signal. When a power source is turned on or off and a channel is switched, a control signal (a switching sound erasing signal) is sent out from the control signal output terminal 4 of the microprocessor and the signal changing-over switch is switched to C by this signal. Since no signal is entered C, a sound signal goes to a non-signal condition and the sound is erased. Thus, by providing the non-signal status to the signal changing-over switch, the switching sound erasing pulse output terminal of the microprocessor and a switching transistor can be omitted and a circuit constitution can be simplified.

Filed: 1978-12-28
Abstract: PURPOSE: To simplify the construction along with a higher position accuracy and higher efficiency by mounting the rotor to a shaft projected at the center of the pole tooth plate with one end of the core fixed to the center thereof while the other end thereof is fixed to the free end of the stator.  
     CONSTITUTION: A stator 1 made of an iron plate having a pole tooth plate 2 at the one end thereof is inserted through the hollow section of the coil frame 3. Both leg pieces of a roughly U-shaped core 5 are caulked at both ends of the stator 1 extended on both ends of the coil frame 3. The rotor is mounted rotatively to the shaft 7 projected on the end of the core 5 fixed at the center of the pole tooth plate 2 with the magnet 6 of the rotor rotatively matching the pole tooth plate 2. Therefore, when the coil frame 3 is formed, only inserting the stator 1 and the pole tooth plate 2 definitely determines the position of pole tooth plate 2 with respect to the stator. Thus, a highly efficient motor can be obtained.
