Title: Developing device
Inventor: KUTSUWADA AKIO
IPC: G03G15/06
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To eliminate the initial character skew and the character scattering of a developing device whose rising ability is low in terms of the specific potential of toner while a cost hardly rises by initially setting the valve of a developing bias voltage impressed on a developing sleeve low, recreating the value as the number of copy increases and setting an upper limit on the developing bias voltage value. SOLUTION: The developing bias voltage value of initial copy operation is set low to about -500V. Developing ability at this time is 400V. The voltage value rises 10V by 10V wherever 100 copies are taken, rises by 100V when the 1000 copies are taken, and controlled while making 600V the upper limit. Thus, the developing ability in the initial copy operation is intentionally lowered so as to restrain the toner from excessively adhering to a photoreceptor, and the developing ability becomes suitable as the specific potential of the toner rises to be specified one, that is, in accordance with the increase of copy number; therefore, the character skew and the character scattering in the initial copy operation can be prevented.

Title: Image projector
Inventor: KATAYOSE MAMORU
IPC: G03B21/38
Filed: 1978-01-26
Abstract: PURPOSE: To prevent a material to be projected such as microfilm from being deteriorated due to temperature by reducing the intensity of an irradiating light after the light irradiating time for projection of the microfilm elapses more than a preset time.  
     CONSTITUTION: When film such as microfilm is located so that shutter operating signals a rise to a low level, a shutter is cocked so that an image is projected by the optical irradiation of the film located and so that a timer circuit 21 starts its operations. When a preset time elapses, the output of the circuit 21 is inverted so that a filter solenoid is magnetized through an OR circuit 23. Thus, the film is irradiated with the weak light having passed through the filter so that the temperature rise of the film becomes lower than a preset level. As a result, the microfilm is prevented from being deteriorated, i.e., from having its color changed due to the temperature of an object. After elapse of a preset time by the timer, when releasing signals are impressed upon a negative logic AND circuit 22, the output of an OR circuit is inverted again so that the normal projecting condition can be invited.

Abstract: PURPOSE:To obtain a DC motor capable of stopping at the prescribed position by normally or reversely rotating the motor with the value D/A converted from the counted value of a reversible counter which adds or subtract the detected rotating speed output by pulses from a shaft encoder. CONSTITUTION:When the output of a counter 16 which adds or subtracts an electric pulse obtained through a shaft encoder as an input 16b and the prescribed counted value as an input 16a becomes zero, the output of a D/A converter 17 is vanished by the normal rotation of a DC motor M. Transistors 31, 32 are turned OFF and transistors 38, 39 are turned ON by the output of the D/A converter 17 through terminals 36a, 37a, 42. The output of an operational amplifier 34 becomes positive at the normally rotating time, transistors 30, 27, 28 are turned ON through a transistor 39 which is turned ON, the motor M is rapidly decelerated and stopped by reverse torque, and is then reversely rotated. When reversed, the output of the operational amplifier 34 becomes negative voltage, transistors 29, 25, 26 are turned OF through a transistor 38, the motor M is abruptly stopped, and is normally rotated.

Title: Interpolating method for robot tracking and device therefor
Inventor: OOTO MASAHIRO
IPC: B25J9/22
Filed: 1994-01-27
Abstract: PURPOSE:To interpolate the start and end point velocities of both start and end point teaching points after setting these velocities at each prescribed level in order to prevent the change of velocity before and after each teaching point when the linear interpolation is applied between two teaching points. CONSTITUTION:The teaching point data designate the velocity Vs at a start point, the velocity Ve at an end point and the maximum velocity Vmax and the maximum acceleration amax between two teaching points respectively. An interpolating operation is performed for each movement of teaching points so that the velocity Vs is increased up to the velocity Vmax by the acceleration amax. Then it is decided for each interpolating operation whether the velocity set at the next interpolating point and the distance set to the end point are reduced at the largest acceleration less than the velocity Vmax and whether the teaching point can arrive at the end point at the velocity Ve. If the teaching point can arrive so at the end point, the teaching point is moved to the corresponding interpolating point. If impossible, the velocity set at the present interpolating point is defined as the first velocity and the remaining distance section is accelerated or decelerated. Then the interpolating operation and the movement are repeated until the teaching point reaches the end point at the velocity Ve.

Title: Paper feeding device
Inventor: SUGA YUJI
IPC: B65H3/68
Filed: 1985-01-18
Abstract: PURPOSE:To transport the paper sheets having a variety of thickness and pull- out the paper sheet inserted between a paper guide and a paper feeding roller by adjusting the separation distance between the paper guide and the paper feeding roller and preventing the press contact between the both. CONSTITUTION:When an adjusting screw 21 is revolved and pushed-in, a paper guide 15 is turned counterclockwise, having a supporting shaft 10 as fulcrum, and the separation distance between the peripheral side surface of a paper feeding roller 3 and an arcuate surface 15a is reduced. When th eadjusting screw is turned in the pulling-out direction, the paper guide 15 is turned clock wise by the repulsive force of a compression spring 16, and the separation distance between the peripheral side surface of the paper feeding roller 3 and the arcuate surface 15a increases. Therefore, the paper sheets having a variety of thickness can be transported by adjusting the separation distance between the paper guide 15 and the paper feeding roller 3. Further, even if the apparatus stops with the paper sheet 2a nipped between the paper feeding roller 3 and a roller 9, the paper sheet 2a can be easily pulled-out in the B direction, since the paper feeding roller and the paper guide are separated each other.

Abstract: PURPOSE:To prevent a package crack by providing a through hole at the center of a chip stage, and stopping the through hole with an adhesive layer, and fixing a semiconductor chip onto this. CONSTITUTION:This semiconductor device has a structure in which an adhesive layer 9 is filled up in a through hole 8 larger than the semiconductor chip 1 provided at the center of a chip stage 3.

Filed: 1989-01-17
Abstract: PURPOSE:To pass through or bypass a computing element and to shorten the arithmetic processing time by preparing two systems of pipelines and at the same time providing a pipeline exchange circuit at the front of each computing element. CONSTITUTION:Two systems of pipelines are prepared together with a pipeline exchange circuit 5 set at the front of each of computing elements 6-9. Thus it is possible to optionally decide whether the picture data should pass through or bypass the computing elements. In the case of two types of pipeline arithmetic operations that don't use the same computing element, e.g., one of both pipeline systems uses the computing elements A6 and B7 and the other system uses the computing elements C8 and D9 respectively, the picture data to be computed are simultaneously and separately outputted on the pipelines. As a result, two types of pipeline arithmetic operations can be carried out at one time. Then the arithmetic processing time is extremely shortened.
