Abstract: PURPOSE:To reduce the ripples in the primary current and the secondary current by controlling switching elements with the phases different from each other, while maintaining specified pause time, in the same primary transformers, and controlling them with the different phases so that they may complement each pause time, between the different primary transformers. CONSTITUTION:First and second transistors 8 and 9, which correspond to each input part 3a and 3b of the first primary transformer 3, are supplied with control signals IB1 and IB2 whose phases are different by approximately 180 deg. while maintaining dead times in front and in rear. Third and fourth transistors 10 and 11, which correspond to each input part 4a and 4b of a second primary transformer 4, are also supplied with the control signals IB3 and IB4 in the same relation. To the control signal IB1, the control signal IB3 is different in phase by about 90 deg. so that it may complement each dead time.

IPC: H04N5/232
Filed: 1982-12-17
Abstract: PURPOSE:To detect electronically a focal position by moving a lens based on a function obtained by differentiating a video signal. CONSTITUTION:Light from an object passes through a lens 1 and is led to an image pickup section 2, where the video signal is obtained. The video signal is differentiated by a differentiating circuit 3 and the envelope is obtained by a peak detecting circuit 4. The part surrounded by the upper envelope and the lower envelope is integrated timewise by an integration circuit 5.

Title: Speed sensor
Inventor: HOSHINO AKIHIKO
IPC: G01P3/44
Filed: 1988-09-07
Abstract: PURPOSE:To detect speed with high accuracy with reduced ripples even when a shaft of a resolver is deviated from the center by setting an exciting frequency and a clock frequency of said resolver respectively from outside. CONSTITUTION:An exciting circuit 2 generates a sine wave of two phases, sintheta0, -costheta0 upon receipt of an output theta0 of a follower counter 3. The sine wave sine theta0, -costheta0 excites a winding of a two-phase stator. If a reference frequency f1 and a clock frequency f2 are changed such that f2/f1 becomes constant, the rotating speed omegar can be operated from a counting value SIGMAtheta0 of a counter 6 based on an equation omegar=(K.f2/f1)SIGMAtheta0 even when a constant (k) is not changed. Further, if the reference exciting frequency f1 is changed such that f2/f1 is constant, with the clock frequency f2 being changed in correspondence to the detected speed by a frequency setter 7, the speed can be detected with less components of rotating ripples while a necessary accuracy is secured in the whole range from low to high speed.
