Title: Vibration-type drive device and image-forming apparatus
Inventor: HAYASHI TEI
IPC: G03G21/14
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To reduce the wasteful wear in the frictional pretrial of a sliding part, and to attain long life by stopping a control means for driving, based on the speed detection information of a vibration-type actuator via phased deceleration within the allowable driving range of emergency stop in accordance with to the input of an emergency stop command. SOLUTION: Two drive circuits are used for driving a single vibration actuator 25, and each of pulses with phases of 0, 180, 90, and 270 degrees is added to primary-side MOSFETs 19-22 of transformers 23 and 24. A pulse with a phase difference of 90 degrees is outputted from a pulse formation circuit 7 to each of the two circuits. Based on speed information from a speed detection means 26 of an actuator (a body to be driven), the pulse control circuit 7 is controlled so as to reach the value of a speed command (target speed) by a speed control circuit 8. At emergency stop, a pulse width is changed so that the stop is made through the change in a plurality of pulse widths until the stop, thus reducing the speed difference between the actuators at stop action and the stresses given among the actuators and equipment.

Title: Split rolling bearing
Inventor: NAKAGAWA YUICHI
IPC: F16C33/60
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To realize accurate natural splitting of an inner ring or an outer ring in a split rolling bearing with the inner ring or outer ring bisected along an axis. SOLUTION: A splitting cutout part 20 is provided only at one axial end part of an inner ring 1. The cutout part 20 includes a notch part 21 of nearly V-shape, and a slit 22 axially extended from the tip of the notch part 21.

Inventor: KOBAYASHI MICHIYA
IPC: G02F1/136
Filed: 1991-12-27
Abstract: PURPOSE:To realize high quality display having sufficiently high luminance and controlled display defects. CONSTITUTION:Since a black matrix 108 is disposed on the TFT substrate side of this liq. crystal display element but is not disposed at parts confronting scanning lines 104, electric capacity is not formed between the matrix 108 and the scanning lines 104 made of a metal or semiconductor through an insulating layer, accordingly the problem of occurrence of display defects due to such electric capacity is solved.
