Title: Motor control method
Inventor: SEKIGUCHI MINORU
IPC: H02P21/05
Filed: 1987-03-20
Abstract: PURPOSE:To eliminate torque unevenness and perform a smooth driving with little speed error by adding offset to alternating current. CONSTITUTION:While a separate motor 1 is driven by sine and cosine waves beforehand, offsets and amplitudes of said waves are varied so that optimum offsets and amplitudes may be obtained. Thus, sine and cosine waves having offsets and amplitudes according to said optimum offsets and amplitudes are housed in memories 22, 23. Also, sine and cosine waves for forward and reverse rotations are housed in memories 22, 23 according to a direction of rotation and selected by said direction of rotation r. When the direction of rotation r and target speed vC are given, sine and cosine waves set at the optimum offsets and amplitudes are outputted from the memories 22, 23.

Abstract: PURPOSE:To facilitate the adjustment of phase of a dielectric resonator and the coupling between a transmission line and a varactor loop and to reduce the variance of the characteristic by fixing a dielectric resonator to a support rod having a mount face with a tilt angle and moving and turning the support rod so as to fix the support rod. CONSTITUTION:A dielectric resonator 1 connecting to a mount face of a support rod 7 having the mount face with a tilt angle with respect to a lower support face is put in a slit 8 and an optimum phase 5 for the coupling between the dielectric resonator 1 and an oscillating element 2 is obtained by moving the dielectric resonator 1 along the slit 8. Moreover, the dielectric resonator 1 is turned to vary the coupling between the dielectric resonator 1 and a transmission line 3 and the coupling between the dielectric resonator 1 and a varactor loop 4 and after the position and the tilt at which an object oscillating characteristic is obtained are found out, the lower face of the support rod 7 is fixed. Thus, the phase adjustment between the dielectric resonator 1 and the oscillating element 2 and the coupling between the transmission line 3 and the varactor loop 4 are facilitated and the variance in the characteristic at the time of fixing is reduced.

Title: Pulse generating circuit for solid-state television camera
Inventor: SATOU KAZUHIRO
IPC: H04N3/14
Filed: 1981-05-06
Abstract: PURPOSE: To obtain a solid-state camera scanning signal which has an excellent SN ratio by generating a pulse train with a prescribed vertical scanning frequency from a pulse train with a vertical scanning frequency generated by dividing the frequency with a horizontal scanning frequency in two modes.  
     CONSTITUTION: The frequency of a horizontal blanking pulse 34S is divided by a counter 61 to generate two pulse trains 61S and 62S differing in mode. Those pulse trains are used by an FF62 to generate a signal for controlling the frequency division mode of the counter 61. An FF64 is set by the output of the counter 61 and reset by the output of a counter 63. On the basis of the output of the counter 63, a decoder circuit 65 generates a vertical blanking pulse 65A, a vertical synchronizing pulse 65B, and a vertical input pulse 65C. The output of the decoder 65 is delayed by 1H delay circuits 67∼69 having two minutes delay and selected by a selecting circuit 66 to generate a vertical blanking pulse 50A, a vertical synchronizing pulse 50B and a vertical input pulse 50C for the interlaced scanning of a solid-state camera. Thus, scanning pulses having an excellent S/N ratio are obtained.

Title: Cleaning device using web
Inventor: KASAMURA TOSHIROU
IPC: G03G21/00
Filed: 1980-05-20
Abstract: PURPOSE:To wind a web roughly at every fixed rae by regulating the oscillating angle of an oscillating lever according to the rate of the change in the position in which the connecting plate connecting a web let-off shaft and a take-up shaft  changes according to the increase or decrease in the amount of the web. CONSTITUTION:As an eccentric cam 39 revolves at fixed periods in the direction shown by arrow C in synchronization with the paper feeding of an image forming apparatus, an oscillating lever 31 turns counterclockwise against a spring 40, by which a web take-up shaft 4 is also revolved, and taking-up of a web 2 is thereby accomplished. At the return turning of the lever 31 owing to the turning in succession to the cam 39, the shaft 4 is not revolved backward. In this way, the saft 4 is turned intermittently by the reciprocative oscillation of the lever 31 along with the  revolution of the cam 39, whereby the taking-up is accomplished. As the winding  diameter of the web 2 decreases, a connecting plate 36 turns and displaces gradually in a counterclockwise direction (e) around the shaft 14, and along with this, the  return position of a cam follower 32 changes gradually, thus the oscillation angle of  the lever 31 by the cam 39 also decreases gradually.
