Title: Carrier for electrophotography
Inventor: NAGATSUKA IKUTARO
IPC: G03G9/113
Filed: 1989-11-02
Abstract: PURPOSE:To stabilize the electric resistance and electrostatic charge quantity of the carrier and to improve image quality by adding a coupling agent to a coating layer which contains titanium dioxide and is provided on the surface of the carrier. CONSTITUTION:The coupling agent is added into a coating soln. to allow the uniform dispersion of the titanium dioxide powder into the coating layer at the time of forming the coating layer by applying the coating soln. contg. the titanium dioxide powder onto the surface of the carrier formed by dispersing magnetic powder into a binder resin. Coupling agents of a titanium system or aluminum systems are most suitable as the coupling agent. The titanium dioxide powder is uniformly dispersed into the coating resin by the coupling agent in such a manner. As a result, the stable control of the electrostatic charge quantity and electric resistance is possible and the images having high quality are obtd. without being affected by the fluctuation in environmental conditions. The prolonging of the lift of a developer is possible as well.

Title: Image sensor
Inventor: YOSHIMI MAKOTO
IPC: H04N5/335
Filed: 1985-12-20
Abstract: PURPOSE:To obtain an image sensor adapted for high integration with extremely less influence of noise by laminating a plurality of sensor blocks made of circuits for digitizing output signals of an optical sensor and a sensor formed on a thin semiconductor film as cells. CONSTITUTION:The potential of a signal line 44 does not almost change when no light is incident, but the potential of the line 44 drops in response to the light intensity when sufficient light is incident. The potential of a dummy line 45 does not almost alter. Accordingly, when a sense amplifier 43 is driven at a time T1, a detector produces '1' or '0' digital output in response to ON/OFF of the light. Since the incident light intensities of sensor blocks 20 are different, the blocks 20 obtain digital outputs in response to the light intensities in one photoelectric conversion cell 10. In other words, three types of detection outputs are obtained in response to the light intensities. Thus, an image sensor which can obtain light and shade image information can be achieved.

IPC: H02H3/16
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a method for preventing shared accidents in an earth leakage breaker resulting from parallel capacitance. SOLUTION: In a system where a plurality of devices 5 are connected with a plurality of transformers 1 with ground through respective ground leakage breakers 4, if sound devices 5B have parallel capacitance 9 when any device 5A develops a line-to-ground fault, the ground-fault current flowing to the parallel capacitance 9 causes a 'shared accident' which causes the ground leakage breakers 4B of the sound devices 5B to trip. To prevent this, a grounding resistor 10 is placed on the ground side of the transformers 1A for the device 5A not provided with parallel capacitance 9, thereby suppressing current to the parallel capacitance 9 at a line-to-ground fault.

Title: Examining method for lsi wafer
Inventor: SAKAI TOSHIAKI
IPC: H01L21/66
Filed: 1987-11-12
Abstract: PURPOSE:To improve the accuracy of measurement on condition of a wafer by contacting a contact sheet which is formed by furnishing conductive bumps on a bendable film, to metal pads of an LSI water. CONSTITUTION:Conductive bumps 3 and a drawing-out wiring layer 4 connected to the bumps 3 are formed on a bendable film 2 to make a contact sheet. The examination of an LSI wafer 5 is carried out by contacting the bumps 3 to metal pads 6 of the water 5. Since the bumps 3 and the pads 6 can be contacted at an adequate pressure by the elasticity of the film 2 itself, and the pressure is not necessary to be too large, in such a composition, no large plastic deformation is given to the pads 6, and the contact frequency of the pads 6 can be increased. Moreover, the pads 6 can be made smaller than a probe needle, and can respond to a chip with inner pad. In such a composition, a measurement of a high accuracy and a high reliability on condition of the wafer can be carried out.
