Title: Motor
Inventor: HIRASHIMA NOBUHIRO
IPC: H02K21/24
Filed: 1989-05-29
Abstract: PURPOSE:To reduce cogging torque by making the void length between a magnet of a salient pole in an armature core and an opposing part to the magnet above longer in the circumferential side edge section than in the circumferential center section. CONSTITUTION:The void length between a magnet 1 of a salient pole 3 in an armature core 2 and an opposing part to the magnet 1 above is made longer in the circumferential side edge section than in the circumferential center section. Consequently, the flux at the circumferential side edge section gets weaker than the flux at the circumferential center section in an opposing part 4 to the magnet 1 of the salient pole 3, so that the flux change gets low when the opposing part 4 to the magnet 1 of the salient pole facing one of the poles of the magnet 1 is switched over to face the adjacent pole and the cogging torque is reduced.

Title: Bias circuit of frequency converter
Inventor: SOGOU HIROYUKI
IPC: H03D7/02
Filed: 1984-06-29
Abstract: PURPOSE:To attain the reduction of adjusting man-hours and cost reduction by connecting two diodes connected in series to flow a forward current across a part where a resistor and a power supply are connected inseries in parallel across a variable resistor and connecting a slider of the variable resistor and the connecting point of the two diodes. CONSTITUTION:Supposing that a DC voltage Ea is fed across the diodes 2, 3 connected in series and a voltage Eb is fed to the connecting point respectively, bias voltage of the diodes 2, 3 are respectively Ea-Eb and Eb. On the other hand, since the DC voltage Eb is a voltage obtained by dividing the DC voltage Ea by the slider of the variable resistor 16, the Eb is varied by moving the position of the sliding terminal, and the change in the voltage Eb changes the bias voltage of the diodes 2, 3. That is, when the bias voltage across the diode 2 is increased by moving the sliding terminal of the variable resistor to the common side, the bias voltage applied to the diode 3 is decreased, then the bias voltage is set to a position balanced nearly by adjusting the diodes 2, 3 at the same time.

Abstract: PURPOSE:To prevent the generation of unusual noise at the time of switching operation by making the connection of a large diameter pulley and a small diameter pulley via a one-way clutch and a spring clutch respectively, and carrying out the drive of rotation with one of said pulleys in accordance with the output shaft speed of an engine. CONSTITUTION:When the engine speed is below a defined value, the lever 17 of a spring clutch 5 is brought into contact with a spring 15 and the rotation of a small diameter pulley 4 is transmitted to a rotor 11 and, further, to the rotary shaft 2 of a rotary vane type compressor 1 via an armature 8. In this case, the inner ring 6b of a one-way clutch 6 is rotated at a high speed while the rotor 11 is connected to the small diameter pulley 4, whereas, the outer ring 6a, together with a large diameter pulley 3, is rotated at a low speed. After that, when the engine speed becomes above the defined value, the lever 17 is rotated due to centrifugal force disconnecting the clutched condition of the spring clutch 5, the outer ring 6a is rotated at a higher speed than that of the inner ring 6b, and the rotation of the large diameter pulley 3 is transmitted to the rotary shaft 2 via the one-way clutch 6. Thereby, any unusual noise due to switching operation is not generated, while also preventing excessive cooling.
