Patent JP-H0643771-A (JP)
Title: Electrophotographic recorder
Inventor: OKANO YOSHIAKI
IPC: G03G15/00
Filed: 1992-07-27
Abstract: PURPOSE:To record a high-quality image by making the circumferential speed of a photosensitive body different from the feeding speed of a recording medium at the contact position of the photosensitive body such as a photosensitive drum with the recording medium such as recording paper. CONSTITUTION:The feeding speed of the recording paper between the photosensitive drum 1 and a transfer roller 51 is nearly equal to the circumferential speed V2 of the transfer roller 51 in general. This is because toner is attached to the photosensitive drum 1, and the coefficient of friction to the recording paper is smaller than the roller 51, consequently the recording paper is fed by the transfer roller. The feeding speed of the recording paper is V2, and different from the circumferential speed V1 of the photosensitive drum 1. Thus, rubbing is caused between the surface of the drum 1 and the recording paper. Mechanical force is generated in the tangential direction of the surface of the drum 1 by the rubbing, and the auxiliary transfer of the toner from the drum 1 on the recording paper is performed also by this scraping force.

Title: Surface treating method
Inventor: ONO TETSUO
IPC: H05H1/46
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To prevent the surface of an insulating film from becoming an abnormal shape due to local electrification at the time of etching the insulating film by etching the insulating film while a conductive layer is formed on the surface of the insulating film. SOLUTION: The part of a sample 1 which is not coated with a resist 2 is etched by injecting electrons 5 and implanting ions 6 into the sample 1 in plasma. At the time of etching an insulating film 2, such a gas as C4 F8 containing carbon and fluorine is used and the etching is made in a state where a CF-based polymer film 4 is deposited on the sample 1 in the plasma. During etching, the ions 6 are perpendicularly implanted, but the directionality of the electrons 5 becomes worse and a large portion of the electrons 5 is made incident to the side wall of a hole, because the electrons 5 are decelerated in a sheath. Therefore, the etching is performed while a conductive layer 7 is formed on a polymer film 4 which is an insulating film. When the etching is performed in such a way, the electrons 5 move in the conductive layer 7 and can be recoupled with the ions 6. Therefore, the shape of the sample 1 does not become abnormal when the sample 1 is etched, because no local electrification occurs in the hole and the ions 6 are perpendicularly made to the sample 1.

Title: Insulated superconductive wire
Inventor: MORIAI HIDESUMI
IPC: H01B12/02
Filed: 1982-11-16
Abstract: PURPOSE:To obtain a stable superconductive coil which is free from short- circuiting between the adjacent turns of the coil wire and large in current density and is efficiently cooled by a refrigerant, by longitudinally coating a wire with a thin insulating tape such that at least one of the sides of the cross- section of the wire is exposed, thereby to insulate all the curved portions of the wire. CONSTITUTION:A thin insulating tape, e.g., a tape 4 with a thickness not greater than 0.15mm. which is formed by coating a polyimide film with a thermosetting resin or an adhesive, is employed to coat a flat square superconductive wire 1 such as to cover the two shorter-side surfaces and the curved portions of the wire 1, the other two surface being not insulated. A coil made from such insulated superconductive wire is free from the fear of failure in insulation arising from the thinness of the insulating tape 4, since the insulating tape 4 forms two insulation layers between the adjacent turns of the wire. In addition, since the curved portions of the wire are coated with the insulating tape 4, any displacement between the adjacent turns of the wire will not cause short-circuiting between the turns. The portions of the wire which are not insulated are efficiently cooled, since they are allowed to contact with a refrigerant.

Filed: 1989-08-01
Abstract: PURPOSE:To prevent the concentrated deterioration of after-worked part from occurring and consequently obtain inorganic board having favorable resistance to frost damage by a method wherein mixed stock of cement and silica is dusted over a part corresponding to the position, at which cutting or pressing is performed at the following process, of seed coating made on a felt belt by sheet-making method. CONSTITUTION:When board material is made by sheet-making method, mixed stock of cement and silica for the enhancement of structural strength is dusted in advance at the working position, at which cutting or pressing is performed at the following process, of the board material and, after that, the resultant board material is laminated onto a making roll. At this time, the thickness of the board material becomes uniform by the laminating compressive force on the making roll and the pressure at the pressing into flat board in the following process. Accordingly, when work such as cutting or the like is performed, the bad effect due to said work is effectively prevented from occurring, since the density of the cement matrix of the worked part is enhanced in advance. Since the making of the board material concerned is performed under the condition that the density of the cement matrix of the part to be worked is made to be higher, the deterioration of the resistance to frost damage due to after-working is prevented from occurring and consequently a board material having uniform strength as a whole can be made.
