Title: Single-phase synchronous generator
Inventor: KOJIMA JUNICHI
IPC: H02K19/16
Filed: 1987-05-18
Abstract: PURPOSE:To decrease the size of a braking winding and the thickness of a short-circuit ring, by constituting a stator winding from two phase zones (coil groups) deviated in phase at 90 deg. in electrical angle. CONSTITUTION:Phase zones 1d and 1e of a stator winding is arranged to the positions with a phase deviation of 90 deg. in electrical angle. The output of this single-phase two-pole synchronous generator is taken out separately from the two phase zones. When a balanced load is connected to the two phase zones 1d and 1e, the current equal in size and deviated in phase at 90 deg. flows through each winding. The magnetomotive force disappears which is supposed to rotate at the synchronous speed with a rotor in the opposite direction. Only the magnetomotive force is found rotating at the synchronous speed with the rotor in the same direction. When the load is unbalanced, however, the magnetomotive force is generated rotating in the opposite direction of the rotor. Even so, the value of the magnetomotive force will be merely 1/2 of a conventional single- phase generator at the maximum.

Title: Signal processing circuit of solid-state image pickup device
Inventor: MURAKAMI TOSHIO
IPC: H04N5/335
Filed: 1980-09-03
Abstract: PURPOSE:To eliminate only a leaked component, by generating a signal, which has a waveform resembling a leakage clock pulse component, from an original horizontal clock pulse applied to an image pickup element and by reversing the polarity of the signal and by applying it to the input of a preamplifier circuit.
