Title: Electroplating equipment
Inventor: MORI ATSUSHI
IPC: C25D21/14
Filed: 1990-05-25
Abstract: PURPOSE:To easily replenish a consumptive anode and to prevent electric resistance from being increased by corrosion of a contact in a power supply route by utilizing an anode holding device having a specified structure, in the case of plating Al in a treatment tank in the corrosive atmosphere. CONSTITUTION:A plurality of rodelike anodes 85 are horizontally held to the inside of an anode holding device 82. Both end parts of the anode 85 are inserted into the grooves 84 and held. The anodes 85 are vertically overlapped with each other, and held to the anode holding device 82 in a state wherein these are mutually slipped to the work W side and to the opposite side thereof. Electricity is supplied to an anode 85 via the anode holding device 82 from an arm 91. Two pieces of anodes 85 are vertically adjacently connected and mutually pressure-welded. Moreover, one side of anode 85 is slipped to the end wall 86 side, in comparison with the other anode 25, and strongly pressure-welded to this end wall 86. Accordingly, current surely flows to the anode 85 from the end wall 86. Since the anode holding device 82 is widely opened to the work W side, current directly flows mainly between the anode 85 and the work W. As a result, the possibility is prevented wherein the end wall 86, etc., are corroded.

Title: Corona electrifying device
Inventor: TAKEUCHI AKIHIKO
IPC: G03G15/02
Filed: 1985-06-21
Abstract: PURPOSE:To improve the service property by a simple constitution, by connecting in series a varistor and a Zener diode to a grid of a corona electrifying device and applying a bias voltage, and selecting and switching the number of Zener diodes to be used, in accordance with an electrifying function of a photosensitive body. CONSTITUTION:The potential of a photosensitive body is influenced by the grid potential of an electrifying device. When an electrifying function of a photosensitive body 1 is inspected in advance and a correct bias value of a grid 4 is displayed at every photosensitive body, a shadow potential can be set to a correct value by switching contacts A-E in accordance with its display value, when replacing the photosensitive body. When four pieces of Zener diodes 7 of 51V rating, and one piece of varistor 6 of 680V rating are used, the varistor 6 generates a voltage of 640V being lower than a rated value, since a current flowing to the grid 4 is 100-150muA, and on the other hand, the Zener diodes 7 generate 50V of about a rated value per piece, and the adjustment can be executed extending from 640V to 840V at intervals of 50V. Accordingly, a variance of an electrifying function of the photosensitive body can be corrected.

Title: Information recording and reproducing device
Inventor: ODA TOSHIYUKI
IPC: G11B7/0055
Filed: 1989-06-01
Abstract: PURPOSE:To record information in a short time by reading an erasing command stored in a storage means when an access command is not in existence and outputting it to an information recording and reproducing means to carry out an erasing operation. CONSTITUTION:Even when the erasing command is received from a host system 15, the erasing command is once stored without performing the erasing operation immediately, and the erasing operation is executed based on the stored erasing command during no access command from the host system 15 to the device which is hence under the standby state. Consequently, a command for erasing a block recorded with a disused data is outputted in advance by the host system 15, so that the erasing operation in the information recording and reproducing device 10 is executed during the time when other processing is being executed in the host system 15. By this method, the erasing operation is not needed at the time of writing a data to a disused block, thus promoting the data write speed.
