Abstract: PROBLEM TO BE SOLVED: To shield the radio wave leaked to the exterior to the maximum and to effectively protect a human body by forming a plurality of discontinuous transmission routes in a choke as a radio transmission route, and specifying the lengths of the routes. SOLUTION: The radio transmission route of a choke has first transmission routes A1, A2 formed from a first opening 41 to the inner surface of a choke lower wall 24, second transmission route B formed from the second opening 42 formed from the end of a divided wall 27 to the choke lower wall 24 to the inner surface of the choke outer wall 25, and third transmission route C from the third opening 43 formed from the end of the wall 27 to the choke outer wall 25 to the inner surface of the choke upper wall 26.

Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To automatically return to a shuffiing operation, even when the shuffling operation is disturbed by detecting an error of a read address of image data at the present time and initializing a shuffling circuit. SOLUTION: A read address generating part (operating part) 108 produces an output address of the next frame data from an output of address memory. An initialization address generating part 109 produces a write address of frame memory at the initializing. A selector 110 selects an output of the part 109 and outputs it at initializing of a shuffiing circuit and selects an output of address memory 107 and outputs it at the time of normal operation. An address error detection circuit 111 turns an output of the selector 110 into an input, counts a memory address that is supplied to the frame memory, detects an address error and reinitializes the shuflling circuit, when the address error has taken place.

Abstract: PURPOSE:To obtain an excellent print without a fringe even if printing speed is increased and the design precision of a machine is made rough by mechanically separating toner stuck to a nonimage part on an electrostatic latent image carrier through the use of a brush-like cleaning member, after development. CONSTITUTION:The layer of one-component toner 4 on a toner carrier 1 is brought into contact with the electrostatic latent image carrier 5, to actualize an electrostatic latent image 6. A brush-like toner cleaning member is provided to remove the toner stuck to a fringe part generated on the circumference of the image part of the electrostatic latent image 6, on the downstream side of a developing unit and the upstream side of an electrostatic transfer mechanism As this cleaning member, a fur brush on which thin fibers are implanted and a magnetic brush formed in such a manner that a magnetic substance carrier grain is stuck to a magnet are used. The sticking force of the toner after the development in the fringe part is weaker than that of the image part. Therefore, when a brush is brought into contact with the electrostatic latent image carrier 5 after being developed, while being rotated, mainly the toner of the fringe part can be removed.

Title: Contact of breaker and manufacture thereof
Inventor: TSUCHIKAWA MIYUKI
IPC: H01H11/04
Filed: 1991-12-18
Abstract: PURPOSE:To reduce metal evaporation by forming the width of a slit cut and formed by a blade, smaller than that of the blade, and so on. CONSTITUTION:After a slit 20 by which a contact part 10 is divided in the circumferential direction, is cut by a blade, and when it is heated and is plastically deformed by applying outside force, the width of the slit 20 becomes smaller than that of the blade, while the slit part 20 is tilted to the symmetrical axis by twisted deformation. The surface of the contact part 10 that produces metal evaporation is practically reduced, while the amount of metal vapor is reduced and metal evaporation is thus reduced. The current running in the contact part at the time of current break has a circumferential component, while electromagnetic force for driving arc in the circumferential direction is generated by the magnetic flux in the direction of the symmetric axis, and an arc- extinguishing effect is thus improved.
