IPC: G21F9/30
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To provide an electrolytic method for convert zirconium waste to the oxide suitable for disposal environment without lowering the treating rate. SOLUTION: In the oxidation of zirconium waste 6 in an electrolysis using a nitrate solution as an electrolyte, (1) the rate of the electrolysis is accelerated by heating the electrolyte 8, (2) a zirconium oxide thin film layer formed on the surface of the zirconium waste 6 and having extremely low electric conductivity is continuously stripped with the irradiation with ultrasonic. (3) The stripping of the zirconium oxide thin film layer formed on the surface is accelerated by pressing the whole of zirconium or a zirconium alloy from the upper side. (4) The stripping of the zirconium oxide thin film layer formed on the surface is accelerated by continuously giving impact to the whole of zirconium or the zirconium alloy.  In the case that the zirconium waste is relatively small and the surface is covered with the oxide, (a) the electrolyte is stirred and (b) the electrolyte is fed to a waste housing cell to remove thin chips of zirconium oxide from the inside of the electrolytic cell.

IPC: G03G15/06
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To facilitate the adjustment of the density of an image and the prevention of a fog, with voltages. SOLUTION: The voltages are applied to a developing sleeve 50 by a density electrode 71 and a recovery electrode 72. The density electrode 71 is arranged on the upstream side in a developing region 53, to apply the DC voltage V1 for moving magnetic toner from the developing sleeve 50 to an electrostatic latent image on a photoreceptor drum 6. The recovery electrode 72 is arranged on the downstream side in the developing region 53, to apply the DC voltage V2 and the AC voltage V3 for recovering the magnetic toner to the sleeve 50 from a nonimage region on the drum 6.  For instance, when the potential of an exposed region is defined as VL and the potential of an unexposed region (electrostatic latent image region) is defined as VD, at the time of attaining normal development (a toner charge polarity is negative), the voltages Vl, V2 and V3 are adjusted as follows; VD>=V1>=VL, VD-V1>=Vi and V1>=VL>=Vf and VD>=V2>=VL and |V2+V3| max <=VD. Where Vi denotes a potential difference for obtaining a desired image density and Vf denotes a potential difference for preventing the fog.

IPC: H04N1/028
Filed: 1989-12-19
Abstract: PURPOSE:To select required picture information and false picture information effectively by providing a slit body between an optical system and a photoelectric converter. CONSTITUTION:The required information in picture information sent from an optical system 3 passes through a slit body 9 and the image is formed on a photoelectric converter 4.

IPC: A47L9/28
Filed: 1990-11-29
Abstract: PURPOSE:To improve the reliability and precision of the control of the suction pressure of a cleaner by providing a control means which controls a suction motor so that the difference between the optimum suction pressure and the actual suction pressure may be made small. CONSTITUTION:A pressure sensor 5, a suction motor 7 supplying suction pressure P1, and a dust pack portion 8 which is between them and where sucked dust is accumulated, are provided at a suction structure portion 4. In the case of being positioned on a carpet 12, the wheels 3 of a self travel type vacuum cleaner 1 sink into the carpet 12 due to the carpet 12 possessing elasticity, and an opening h2 between the structure 4 and the carpet 12 foundation becomes smaller than an opening h1 between the structure 4 and a flat smooth board 11, and suction pressure becomes P2. Thereupon, control action decreases the rotation number (n) of the motor 7 by a predetermined amount, and controls the motor 7 so that suction pressure may be lowered and the optimum suction pressure P0 may be brought in. As a result, control can be done systematically by making the conditions of a floor surface and the dust a series, so control of high reliability becomes possible.
