Title: Color picture tube
Inventor: KIDA KINJI
IPC: H01J29/70
Filed: 1982-04-22
Abstract: PURPOSE:To eliminate any difference between deflection sensitivity to both side beams and the same to the central beam, with regard to the combination of a color picture tube and deflection yoke, wherein the deflection sensitivity to both side beams is different from the deflection sensitivity to the central beam. CONSTITUTION:12 and 14 denote both side beam emission holes of an electron gun while 13 denotes a central beam emission hole. Also 23 and 24 are deflection magnetic field control elements while 25-30 denote each part of the magnetic field control elements. In said constitution arrangement, the horizontal deflection magnetic field near the central beam emission hole 13 becomes fairly scarcse because much of the magnetic flux is converged by the parts 25 and 26 of the magnetic control elements 23 and 24. Accordingly, the magnetic field control elements 23 and 24 act to weaken the horizontal deflection sensitivity to the central beam 4 thus to enable even coma aberration to be easily corrected.

Title: Pulse motor driving method
Inventor: KAKO YUTAKA
IPC: H02P8/12
Filed: 1989-03-20
Abstract: PURPOSE:To reduce noise, caused by rotary vibration of shaft system due to excessive output torque, by measuring the magnitude and duration of peak current flowing through each driving phase then determining the duration and the magnitude of current of a phase, to be excited next, according to thus measured peak current and duration thereof. CONSTITUTION:A control section 3 reads out current value data from a current measuring section then reads out exciting condition of a phase, to be excited next, from a table contained in a memory 4 and controls a pulse motor driver 5. Upon increase of load torque due to some cause, e.g. when the current increases from a peak value Ip3 to Ip5, the control section 3 immediately reads out ON time Ton4 for the phase to be excited next from the table and controls the pulse motor driver 5 such that the ON time for the phase to be excited next will be Ton4. Consequently, peak current Ip7 flows through a motor to increase allowable load torque so as to compensate for increase of load torque.

IPC: G02B7/28
Filed: 1986-03-25
Abstract: PURPOSE:To shorten a processing time and to attain exposure control based upon up-to-date photometric information by executing automatic exposure control processing in parallel with automatic focus adjusting processing for controlling the driving of a photographing lens at a low speed immediately near focusing. CONSTITUTION:A driving distance up to the focusing position of the photographing lens A calculated by a microcomputer in a sequence control means B is outputted to a driving means C and also outputted to an operating state control means D. When the applied signal exceeds a prescribed value, the control means D allows the control means B to execute autofocusing (AF) processing and makes the driving means C is high speed driving state. When the signal indicating the driving distance drops less than the prescribed value, the control means D turns the driving means C to a low speed and allows the control means B to execute automatic exposure (AE) control processing. Thus, the processing time is shortened and the AE processing based upon the up-to-date information can be attained.
