Patent JP-H03237813-A (JP)
Title: Pulse generating circuit
Inventor: IWATA AKIHIKO
IPC: H01S3/097
Filed: 1990-02-15
Abstract: PURPOSE:To avoid increase in an earth capacitance with simple constitution by employing a DC power supply such as a battery as a gate power supply. CONSTITUTION:A gate power supply 15 supplying power to each gate circuit 11 consists of a DC power supply 12 and a capacitor 14 receiving a voltage of the DC power supply 12 via a diode 13 and holding it. That is, since a DC power supply such as a battery together with the capacitor 14 is used for the gate power supply 15, the use of a transformer causing increase in an earth capacitance and line unbalance is avoided. Thus, the constitution is simplified and the cost is reduced and the voltage division of the power supply to each gate circuit 11 is optimized easily.

Title: Combustion control of internal-combustion engine
Inventor: SUEMATSU TOSHIO
IPC: F02P5/15
Filed: 1983-03-01
Abstract: PURPOSE:To prevent the engine from overheating when a suction amount detector is abnormal by a method wherein fuel injection amount and ignition timing are controlled based on preset lower limit values when the opening degree of a throttle valve is larger than a predetermined value and a ratio of suction air volume to engine revolving number is smaller than a predetermined value. CONSTITUTION:Under the operation of the engine, the data of the engine revolving number N are read into the RAM of an electronic control circuit 20 from the detecting signal of a revolving angle sensor 18 and the data of suction air amount Q are read into the RAM of the same circuit from the detecting signal of an airflow meter 14, thereafter, Q/N is operated. Next, Q/N is decided whether it is smaller than a predetermined value (c) or not, and when it is NO, the fuel injection amount of a fuel injection valve 6 and the ignition timing of an ignition plug 3 are controlled in accordance with the Q/N. On the other hand, when it is YES, the preset lower limit value is presumed as the ratio Q/N and the fuel injection amount as well as the ignition timing are controlled based on the lower limit value under a condition that the opening degree of a throttle, detected by a throttle opening degree sensor 11, is larger than a predetermined opening degree (full open).

Title: Operating apparatus for brushless motor
Inventor: MAEDA SHIRO
IPC: H02P6/18
Filed: 1990-02-14
Abstract: PURPOSE:To reduce in size a filter circuit and to improve stability at the time of a load variation by arranging a capacitor in series with the rear stage of a voltage divider formed of a plurality of resistors in a filter, and providing an integrator at its rear stage. CONSTITUTION:In the case of a U phase, the induced voltage Vn of an armature winding 4 is divided by resistors 6a, 6b. The voltage dividing ratio is suitably selected to suppress a voltage across the resistor 6b to a low value. Thus, a circuit after the resistor 6b can be formed as a low voltage circuit, and capacitors 6c, 6e used for a differentiator, an integrator can be available with low breakdown strength ones. Since a DC component stored in the capacitor 6c of the differentiator is discharged through the resistor 6b, the DC component does not remain in the capacitor 6c at the time of stopping a brushless motor, it can be smoothly shifted from a next starting time sync operation mode to a position detecting operation mode.
