Abstract: Disclosed herein is a technique for manufacturing a superconducting tape grown epitaxially by a replication process. According to the technique, a long superconducting tape can be manufactured using a loop-shaped base. Further disclosed is a method for manufacturing a metal oxide device which comprises the steps of forming a solvent-soluble separation layer on a base having a single crystal or textured surface, forming a superconducting layer on the separation layer, forming a support layer on the superconducting layer, and removing the separation layer by dissolution in a solvent. According to the method, it is possible to manufacture a superconducting tape consisting of the superconducting layer and the support layer separated from the bath, and having the same crystallinity as that of the base (replication).

Abstract: The present invention is provided to manufacture a low magnetic loss metal tape with biaxial texture and a manufacturing method thereof. The low magnetic loss metal tape has a non-magnetic metal layer deposited on a nickel layer in the form of stack. The low magnetic loss metal tape with biaxial texture is manufactured by the following steps. A biaxially textured nickel layer is formed on a surface of cathode rotating in an electroplating bath including a cathode with single crystalline structure or similary high orientation, and an anode made of high purity nickel. The nickel layer formed on the cathode is then washed in a water bath. Subsequently, a non-magnetic metal layer is formed on the washed nickel layer rotating in a plating bath with a non-magnetic metal solution. The metal tape is finally manufactured by delaminating and winding the nickel/non-magnetic metal layers.

Abstract: Disclosed herein is a reactive sputtering deposition apparatus in which a partition plate is provided between a sputtering target and a substrate. The reactive sputtering deposition apparatus comprises a deposition chamber for creating an inner process atmosphere of the apparatus, a target including a metal material to be deposited, a substrate on which a reaction product of the metal material separated from the target with a reactive gas is deposited, and a partition plate dividing the deposition chamber into a reaction chamber at the side of the substrate and a sputtering chamber at the side of the target and provided between the target and the substrate, wherein an opening is formed through a central portion of the partition plate to allow the metal material separated from the target to reach the substrate.

Abstract: Disclosed is a method for cleaning the contact charger of an electrophotographic apparatus including a photosensitive (photoconductive) drum, developing means, transfer means and main motor, which comprises the steps of applying a charging voltage of a specified level to the contact charger to make the surface of the photosensitive drum keep a surface potential of a given level during rotation of the main motor, cutting off the charging voltage applied to the contact charger and developing voltage applied to the developing means after a specified time so as to transfer the toner of opposite polarity attached to the contact charger to the photosensitive drum, and applying a negative transfer voltage to the transfer means so as to transfer the toner of opposite polarity transferred to the photosensitive drum to a sheet of paper.

Abstract: An image forming apparatus includes detachable expendables such as a photosensitive drum, a toner cartridge, an ozone filter, etc. The image forming apparatus counts a number of papers being printed after replacing the expendable and stores a counting value as an amount of use in a nonvolatile memory, and prints out a status message including the amount of use, periodically or whenever the image forming apparatus is turned on. Further, the status message includes a predetermined test pattern for testing the printing status of the printer. In the light of the status message, the user may predict in advance the proper replacing time and cope with degradation of the images by checking the printing status from the test pattern at any time.
