Filed: 1988-12-13
Abstract: PURPOSE:To obtain an NRZ demodulated signal completely without an error output when a signal in which a logic 1 or 0 continues long by using a demodulating circuit having a means, which stops charging and discharging. CONSTITUTION:A switch 18 uses a P channel MOS Tr, and when the gate of the switch 18 is at a logic 0, terminals 21 and 22 are made into a penetrated condition. A bit synchronizing means 25 outputs a sampling clock signal to sample the NZR signal of a terminal 5 to a line 30. In the means 25, the signal on the line 30 is generated by dividing an output 29 of a reference clock generating means 24.

Title: Single-phase synchronous motor
Inventor: MIYAZAWA HIROSHI
IPC: H02K21/14
Filed: 1990-11-20
Abstract: PURPOSE:To permit self-start with an initial signal by fixing the permanent magnet provided at the flange to the position deviated from the magnetically stabilizing point positions of magnetic teeth and a rotor permanent magnet. CONSTITUTION:A plurality of stator magnetic pole teeth 5 are arranged opposite to the pole of a rotor magnet. Moreover, a cylindrical magnet 8 magnetized in multipole lies on one side in axial direction of the rotor magnet 1, being attached to the flange 7. The magnetic pole teeth 5, a stator 4, and the cylindrical magnet 8 constitute one magnetic circuit, and the rotor magnet 1 and the cylindrical magnet 8 constitute one magnetic circuit. Hereupon, in case that there is no cylindrical magnet 8, the position where the center of the magnetic teeth 5 and the center of the pole of the rotor magnet 1 lie on the other becomes the stabilizing point, and it stands still at this position. And if the pole position of the cylindrical magnet is deviated from the stabilizing point position, the stabilizing point position of the rotor magnet slips off being pulled by the cylindrical magnet. The amount of this slippage becomes the driving force in specified direction at start-up. Hereby, self-startup becomes possible without committing an error with the initial signal.
