Title: Dynamic pressure bearing motor controller
Inventor: KAWASHIMA KOTOJI
IPC: H02P6/24
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce rotation period, while the rotary shaft of a dynamic pressure motor is brought into contact with a bearing and reduce the wear of the shaft and bearing. SOLUTION: A velocity command signal and a velocity detection signal related to a dynamic pressure bearing motor are compared with each other by a comparison unit 1 and a deviation (e) is outputted. A driver unit 3 controls a drive current applied to the dynamic pressure bearing motor M so as to reduce the deviation (e). The revolution detection unit FG detects the number of revolution of the motor M. A 1st velocity detection unit 7 outputs the velocity detection signal corresponding to the revolution in accordance with the detection signal of the revolution detection unit FG to the comparison unit 1.  A 2nd velocity detection unit 9 compares its detected velocity with a reference velocity, corresponding to the revolution of 1/2-1/4 of the rated revolution of the motor M, and if the detected velocity is reduced below the reference velocity, outputs a brake signal S to the driver unit 3. The driver unit 3 controls the brake of the dynamic pressure bearing motor M based on with the brake signal S.

Abstract: PURPOSE:To correct the difference of the sensitivity of picture elements of the entire sensor by transferring an output signal of part of picture elements in a sensor chip to a horizontal output line capacitor different from other picture elements so as to vary a read gain from that of the other picture elements. CONSTITUTION:A capacitance CA 65 is a wiring capacitance of output lines 69, 73, 74 and the input capacitance of an amplifier 66 and a signal corresponding to both side end faces of a sensor chip is outputted through the wires 73, 74. Then a signal is sequentially read out of sensor bipolar transistors (TRs) 11-16. Then a signal corresponding to a picture element at both ends is outputted directly to an output line 69 from outout lines 73, 74 of MOS TRs 51, 56 not through horizontal output lines 71, 72. Thus, a signal other than the edge picture element is transferred to horizontal line output capacitance sets CH 61, 62, a signal at an edge picture element is transferred to an amplifier input capacitance C'a 65 as a different horizontal line output capacitance. Thus, an edge gain Gcorner forming the capacitance division of the capacitance C'A 65 as the horizontal output line capacitance from transfer capacitance CT (41-46) is larger than a gain Gcenter in the middle.
