IPC: H02K37/04
Filed: 1989-08-31
Abstract: PURPOSE:To improve vibration and to improve positional accuracy by providing a deviation angle between the center line in each stator magnetic pole and the center line of the magnetic pole tooth of a rotor magnetic pole opposite to this. CONSTITUTION:Stator magnetic poles 11-1' and 11-2 are arranged being slid for each other by 360 deg./6. When the angle (deviation angle) formed by the center line in the stator magnetic pole and the center line of the nearest pole tooth out of the pole teeth of a rotor magnetic pole opposite to this is defined as alpha, those are arranged so as to be 0<=alpha(360 deg./Z). It is Y-connected three external lead wires to the stator magnetic pole, and power is shifted and supplied in order so as to do step driving. Hereby, the number of transistors can be decreased, and a drive circuit is simplified, and it can be constituted at a low cost.

Title: Device for controlling power supply for driving ac motor
Inventor: SHIROCHI SHINJI
IPC: H02P23/00
Filed: 1989-08-30
Abstract: PURPOSE:To generate torque of an electric AC motor almost to a fixed value controlling the total sum of an output DC current to a fixed value by decreasing a commutation overlapping angle of a separately excited inverter increasing an upper limit of an operation possible frequency. CONSTITUTION:When a commutation signal G1 is input, a switch 18 is closed with a firing signal Ph8a obtaining a value corresponding to e-B by a subtracter 22 and with a firing signal Ph8b obtaining a value e+B by an adder 21. As a result, both converters (8a), (8b) obtain in their output DC currents Ipa, Ipb the characteristic as shown in a period G1 of (a), (b). When a commutation signal G2 is input, a switch 19 is closed with the firing signal Ph8a obtaining the value e+B by an adder 20 and with the firing signal Ph8b obtaining the value e-B by a subtracter 23. Thus, the DC current is decreased, only at the time of its commutation, to both inverters decreasing a commutation overlapping angle. A sum of both the currents Ipa+Ipb to each inverter is in a fixed value not changed. In this way, an electric AC motor generates torque almost not fluctuating.

Title: Optical head apparatus
Inventor: HOSHINO ISAO
IPC: G11B7/135
Filed: 1993-09-09
Abstract: PURPOSE:To share optical elements and to simplify an optical system by deflecting the proceeding direction of the reflecting light passing through a beam shaping functional element by means of a deflecting element and guiding the light to a photodetector. CONSTITUTION:A light source 1 is a laser light source and projects anisotropic beams of light. The light beams are turned to a parallel luminous flux by a collimating lens 2, and further shaped to be isotropic by a beam shaping prism 3. Then, the luminous flux is raised by a mirror 4 and guided to an objective lens 5. The luminous flux is condensed by the lens 5, converged and cast onto a recording surface of an optical disc 13, thereby forming fine beam spots. The light reflected at the recording surface of the disc 13 is sent through lenses 5, 2 in the opposite direction to that when the light is guided to the lens 5, and subsequently diffracted and deflected by a holographic element 6 as a deflecting element. The light is eventually detected by photodetectors 7, 8. The output signal is operated at an operational circuit 10 to generate an error signal. Accordingly, a current of a focus driving coil 12 is controlled, thereby controlling the focal position of the beam spots. In this manner, optical elements are used in common and the optical system is simplified.
