IPC: G09G3/20
Filed: 1991-05-29
Abstract: PURPOSE:To enable easy mounting on a display element and to select and drive respective scanning electrodes of the matrix type display element plural times in one operation period, in the driving integrated circuit which drives the scanning electrodes of the matrix type display element. CONSTITUTION:This driving integrated circuit 100 when supplied with a high- level MODE signal selects a signal (e) which goes up to a high level in two cycles of a clock signal CO as a control signal (g) and inputs it to a shift register 12. The shift register 12 inputs this control signal 8g) and shifts it in response to each clock signal CO. The pulse width of the control signal (g) is as long as two cycles of the clock signal CO, so a high-level signal is outputted from one parallel signal output terminal of the shift register 12 for two cycles of the clock signal CO. Each NAND circuit 13, therefore, outputs two pulses successively and two driving pulses (p) are outputted continuously from each of output terminals 16.

Title: Rotor for electromagnetic motor
Inventor: KOUNO KANAME
IPC: H02K1/27
Filed: 1982-07-20
Abstract: PURPOSE:To smoothly rotate a rotor for an electromagnetic motor by composing the motor with a cylinder or a cylindrical post which has poles arranged spirally to the central axis of rotation on the outer peripheral surface, thereby preventing the resonance. CONSTITUTION:A rotor 1 is interposed through a spacer 3 of nonmagnetic material between a pair of electromagnets 2 and 2 formed so that the opposed surfaces are disposed spirally at the contacting line with the cylindrical surface, and a coil is energized. As a result, a rotor 1, in which poles are spirally arranged to the central axis as shown, can be obtained. When the rotor 1 is used as a rotor of an electromagnetic motor, the poles of a stator and the rotor are always displaced from each other, thereby eliminating the abnormal resonance of the rotor. In this manner, the damage can be prevented, thereby generating smooth rotation.

Title: Mechanical disk brake
Inventor: WATANABE NAMIO
IPC: F16D65/18
Filed: 1988-05-24
Abstract: PURPOSE:To obtain a gap automatic regulation mechanism which can be housed within a small capacity by providing at the cylinder bottom portion of a calipers member a sub power transmission system for gap automatic regulation which is converted and transmitted as the axial movement power of a piston only when the rotational quantity of a power screw has surpassed a fixed value. CONSTITUTION:When the lining wear of a friction pad makes progress and an advance quantity which a piston needs in order to press the friction pad against a rotor, becomes correspondingly larger, the rotational quantity of a power screw 11 also becomes larger, so the rotation of a pin 29 causes the rotation of a friction piece 19. The rotation of this friction piece 19 causes an adjuster screw 18 to be rotated, resulting in the piston 7 making an advancement equal to the total alone of the axial movement of the adjuster screw 18 and a rotation amount. At the time of brake release, the piston 7 and the adjuster screw 18 follow a sleep nut 17 and go back without rotating axially and return to initial positions.

Abstract: PROBLEM TO BE SOLVED: To stably obtain appropriate and uniform electrification amount, to prevent fogging and the lowering of image density and to stably obtain a distinct image by producing toner by mixing coloring particles and additive after humidification by spraying the droplets of water to either the coloring particles or the additive. SOLUTION: The toner is produced by mixing the coloring particles and the additive after the humidification by spraying the droplets of the water to either the coloring particles and the additive. By softening electrostatic interaction between the coloring particles and the additive by executing humidifying processing in a method where the droplets of the water are sprayed by using a spray nozzle 7 before mixing both of them, the additive is uniformly dispersed in the coloring particles and the toner having the appropriate and uniform electrification amount is stably obtained. It is desirable to set the volume median diameter of the droplet of the water to <=100 μm. When the droplet diameter exceeds 100 μm, the coloring particles and the additive are aggregated, so that desired electrifying performance is not obtained.
