Title: Developing device
Inventor: SHINDO KAZUNORI
IPC: G03G15/08
Filed: 1994-07-04
Abstract: PURPOSE:To prevent the lowering of potential margin causing surface fogging with respect to the electrostatic charging potential of a photoreceptor, which occurs because the electrostatic charging amount of toner is too high, and a white background staining phenomenon from occurring under low temperature and low humidity environment by reducing load torque at an initial stage and reducing the abnormal rise of the initial electrostatic charging amount of the toner in a developing device using a conductive elastic roller as a toner carrier. CONSTITUTION:Powder 21 consisting of fluororesin particulates is stuck to the surface of the toner carrier 1 consisting of conductive rubber 1b. Since the fluororesin particulates have property that it is electorstatically charged to be negative, the abnormal rise of the initial electrostatic charging amount of the toner is reduced. The fluororesin particulates are consumed to perform development with toner when printing for hundreds of pages is performed, so that the lowering of the electrostatic charging amount thereafter is prevented. Namely, the reducing effect of the electrostatic charging amount by the fluororesin particulates acts only at the initial stage.

Title: Microwave plasma treatment device
Inventor: OHARA KAZUHIRO
IPC: C23C16/511
Filed: 1989-06-16
Abstract: PURPOSE:To enable plasma in large diameter to be produced stably by a method wherein the radiation impedances in the microwave propagation channels from the position of a waveguide connecting to the first cavity resonator to the respective positions of multiple microwave radiating slots to the plasma processing chamber of the first and second cavity resonators are equalized. CONSTITUTION:More microwave power is propagated from the first cavity resonator 1 to the second cavity resonator 2 than to a processing chamber 7. The radiation impedance can be controlled by changing the opening areas of slots 5, 10 and opening pitch diameter of the slot 10. Accordingly, the opening areas and opening pitch diameter are set up so that the microwave radiation impedances in the propagation channel through which the microwaves led in the first cavity resonator 1 are directly radiated in the processing chamber 7 as well as the other propagation channel through which the said microwaves are radiated through the second cavity resonator 2 may be equalized. Through these procedures, the density distributions of the microwave power radiated from the slots 10, 11 to the processing chamber 7 can be equalized.

Abstract: PROBLEM TO BE SOLVED: To provide a repairing means for a gas flow pipe whereby even in a condition gas is provided inside the flow pipe, it can be safely and quickly repaired, and welding is not necessary at all. SOLUTION: In a method repairing a defective part 2 of a hole crack, etc., generated by corrosion of a gas flow pipe 1, first in an external surface of the defective part 2, a magnet sheet 3 having a size covering this defective part 2 is fixed, next its top is covered with a coating material 4 having corrosion resistance and high adhesive force. In this coating material 4, for instance, a two-liquid flake compounded epoxy resin is used.  Here, in an emergency measure of the defective part, a reason for use of the magnet sheet 3 is that in the case of the magnet sheet, without using an adhesive or the like, in addition to the gas flow pipe capable of instantaneously attracting the sheet 3, in hard magnet, a space is generated between itself and the defective part, resulting to be incapable of stopping a gas leak, in the case of sheet-shaped magnet, its adhesion can be made to be fitted to a curved surface of the flow pipe, so that the defective part can be completely shielded.
