Title: Voltage controller of generator for vehicle
Inventor: MAEHARA FUYUKI
IPC: H02P9/14
Filed: 1994-11-10
Abstract: PURPOSE: To provide an inexpensive device which suppresses the drop of voltage at switching in of an electric load, and prevents the hunting at idling. CONSTITUTION: This is equipped with a switching detecting circuit 30, which detects the connected electric load 6, and an exciting current control circuit 40, which changes over the increase speed of the exciting current of a three- phase AC generator 1, and in the case that electric load is not detected, this lowers the increase speed of the exciting current, and in the case that the electric load is detected, this raises the increase speed of the exciting current. When the electric load is not connected, hunting does not occur since the increase of the load of the three-phase AC generator 1 s slow. At when switching in the electric load, the voltage drop of a battery 5 is small since the exciting current is increased quickly.  Since it is necessary only to detect whether the electric power is made or not, the circuit constitution can be simplified, and this can be made an inexpensive device.

Title: Brushless motor
Inventor: OKABAYASHI EIJI
IPC: H02P6/06
Filed: 1993-11-05
Abstract: PURPOSE:To provide a brushless motor having a low noise level in cases of both its start and stationary rotation. CONSTITUTION:An FG pattern 3 is connected with a phase comparing circuit 6 via an FG amplifier 4 and a zero-crossing detector 5. The phase comparing circuit 6 decides whether the rotation of a brushless motor reaches its stationary one or not, and sends coil switching signals to a circuit 9 for processing position sensing signals. Based on the decision result, the phase comparing circuit 6 sends the coil switching signal whereby the motor is driven with six coils when the motor is started, and it sends the coil switching signal whereby the number of the coils which carry currents is switched from six to three when the rotation of the motor reaches its stationary one. The circuit 9 for processing position sensing signals sends signals to a current driver 14 via an amplitude controlling circuit 13. The current driver 14 feeds currents to the coils and drives them.

IPC: E01H11/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To block overgrowth of weeds, and finally deaden them by utilizing a wind pressure caused when vehicles are passed without requiring of scattering of herbicide and use of mowers.

Title: Ink cartridge
Inventor: MATSUI SHINYA
IPC: B41J2/165
Filed: 1988-11-02
Abstract: PURPOSE:To make a recording device compact and at the same time, increase the efficiency of ink discharge recovery action by providing an ink suction device which sucks spent ink from a clearance between an ink head and a cap using a negative pressure generated in a suction pump. CONSTITUTION:If a pressing member 114 is pressed in a normal condition, its tip comes in contact with the top of a suction pump 109. The valve 10 of the suction pump 109 is opened by air in the pump because the suction pump 109 is pressurized resisting its elastic power, then the pump 109 undergoes a compression process. Next, if the pressing member 114 is moved backward in a reverse direction when the air of the pump 109 is compressed to a certain level, the air is expanded with the valve 110 closed by a negative pressure generated in the pump due to the extension of its suction bellows. This negative pressure generates a negative pressure in a spent ink storage section 10 through tube 108, and ink is recovered from a head orifice section through a spent ink suction joint 112.

Title: High frequency lighting apparatus for incandescent lamp
Inventor: HAMAHATA SEIJI
IPC: H05B39/00
Filed: 1989-10-26
Abstract: PURPOSE:To detect over load condition at a terminal period of a lamp or during lighting when excessive current runs so as to protect a device from breaking and prevent error operation owing to rush current at the initial stage of electric power application by installing a detecting condition setting means to alter detecting conditions of lamp current in a protective circuit between time of starting electricity supply to an incandescent lamp constantly lighting time. CONSTITUTION:When a switching device Q6 of a transistor is inserted between a cathode and a gate of a switching device Q5, the switching device is necessarily kept off condition during the switching device Q6 is on from the time of electricity application. If the on period of the switching device Q6 is set to be a proper period from the time of electricity application to of constant lighting condition, even under the conditions of a comparative device Q4 being on owing to rush current running at the time of electricity application, the switching device Q5 is not triggered. Consequently, independently of detecting level of the protective circuit 2, the protective circuit 2 does not stop oscillation operation of a lighting apparatus and thus detecting levels of voltage applied to both ends of an emitter resistor R1 under secondary short-circuit condition at a terminal period of the lamp and that under constant lighting condition can be set.
