Abstract: PURPOSE:To enhance the quality of electrophotography by adding a prescribed slight period of time to or before or after cutting of a photosensitive material and generating an electric field of the direction backward from the direction of ordinary electrifying in the photosensitive material. CONSTITUTION:After the prescribed slight period of time is added to or before or after the cutting of the photosensitive material P, the electric field of the direction backward from the direction of the ordinary electrifying by an electrifying means 1 is generated in the photosensitive material P.

Abstract: PURPOSE:To improve resolution by forming an input face into a thin film shape inside the input window of an envelope, and forming the portion of the input window from a beryllium curved surface of two or more radii of curvature. CONSTITUTION:An input face is formed into a thin film shape inside the input window 110b of an envelope 110 and a phosphor screen 160 is formed directly on the inner surface 110c of an output window which serves as the output side of the envelope 110.

Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To secure a required negative pressure, and reduce frequency at which a throttle opening is shrunk during brake operation, in a vacuum booster device for shrinking the throttle opening when negative pressure of the vacuum booster weakens. SOLUTION: When negative pressure of a negative pressure chamber 12a weakens than a required negative pressure determined based on a master cylinder liquid pressure and increased speed of the master cylinder liquid pressure during operation of a brake pedal 10, opening of a throttle valve 20 is reduced.

Abstract: PURPOSE:To reduce power consumption, to lessen the vibration at a low speed and thereby to attain power-saving in a low-speed rotation and smoothing of the rotation, by substituting a plurality of short pulses for a drive pulse to be impressed on an exciting coil of a pulse motor. CONSTITUTION:When a drive signal is inputted from a main control device 16, a motor controller 17 generates a pulse in the conditions of generation of the pulse corresponding to the drive signal, in other words, by computing a pulse frequency and a pulse width, and impresses it on a pulse motor 14. The number of revolutions of the pulse motor 14 is detected by an encoder 15 and fed back to the motor controller 17 and the pulse motor 14 is driven so that the actual amount of rotation thereof may coincide with the drive signal from the main control device 16. In the case when the drive signal from the main control device 16 specifies a low rotational speed, the motor controller 17 generates a short pulse in a width corresponding to the rotational speed and drives the pulse motor 14 thereby. By making the pulse short in this way, a constant torque characteristic in a low-speed range is obtained and, besides, power-saving can be realized.
