Title: Production of electrophotographic sensitive body
Inventor: KAJIWARA HIDENORI
IPC: G03G5/05
Filed: 1988-01-21
Abstract: PURPOSE:To remove an org. layer in the end part of an electrophotographic sensitive body without generating damaging of the necessary part and unequal film thicknesses by providing a shielding material and removing the org. layer in the end part while protecting the non-removing part by bringing the shielding material into tight contact with the org. layer. CONSTITUTION:After the cylindrical electrophotographic sensitive body 15 is inserted, the spacing between the front end of the shielding material 12 and the hollow cylindrical electrophotographic sensitive body 15 is tightly closed by rising of a cylindrical ring 14. The removing liquid injected from removing liquid injection ports 23, 23' and 24, 24' removes the org. layer at the bottom end of the cylindrical electrophotographic sensitive body 15 but since the front end of the shielding material 12 is in tight contact with the electrophotographic sensitive body 15, the splashing of the necessary org. layer in the upper part of the electrophotographic sensitive body 15 and the confining of such vapor as to erode the surface thereof are obviated. The end part of the org. layer is thereby removed while the necessary part thereof is efficiently protected.

Title: Controlling method of plasma arc heating and softening process for machining of metal
Inventor: SAKAMOTO CHIKAO
IPC: B23B1/00
Filed: 1982-01-29
Abstract: PURPOSE:To control plasma arc heating power, by making full use of cutting resistance produced via the above captioned machining of metal. CONSTITUTION:A cutting tool 4 is attached to the nose of an elastic support bar 5 installed on head 3, through which a workpiece 7 is machined by the cutting tool 4. In advance of this process, a work part of the workpiece 7 is preheated by a softener head 1 held up by a support bar 2. At this time, if a reach of heating is somewhat is shallow in depth, cutting resistance grows large whereby the elastic support bar 5 bends downward. Consequently, the softener head 1 on the nose of the support bar 2 goes down, making th depth of heating power yet deeper. When the depth of heating becomes deeper, the cutting resistance decreased proportionately, so that the softener head 1 goes up and the depth of heating is therefore shallowed. In this way, heating depth is controlled.

Filed: 1989-01-20
Abstract: PURPOSE:To prevent irregularities in a reproduced image due to an decoding error occurring by detecting an encoding unit in which passing between the write and readout operations of a frame memory occurs, and prohibiting the write operation for a detected encoding unit. CONSTITUTION:A write prohibition controller 14 inputs an address on which the write operation is performed and the address on which the readout operation is performed from a write signal generator 12 and a readout signal generator 13 successively, and finds difference between those addresses on the frame memory 1. Also, the controller 14 finds the difference between a write clock and a readout clock from a clock generator 15 and a readout clock generator 17. A line on which the passing occurs is found from two differences, and a write prohibition signal to prohibit the write operation when the write operation to the line is instructed is outputted to a write controller 11. In such a way, the encoding error due to the discontinuity of a code generated at the time of performing the passing between the write operation and the readout operation in the memory 1 can be evaded.
