Title: Formation of image
Inventor: HATTORI YASUHIRO
IPC: G03D13/00
Filed: 1991-03-27
Abstract: PURPOSE:To permit powder to exist at an image part with the superior contrast and permit the writing on a white part by selectively removing the developer on a light exposed part from a photosensitive sheet to a photoconductor and copying the residual developer to an image receiving paper. CONSTITUTION:A developer 17 which is previously electrified is loaded on a carrying roller 13 which is set oppositely to an electrode roller 12. The developer 17 is attracted to the electrode roller 12 by the electric field formed between the electrode roller 12 and the carrying roller 13, and the developer 17 is applied uniformly on a photosensitive sheet 11. When a photoconductor drum 23 is exposed through the photosensitive sheet 11 on which the developer 17 is applied, the polarity of an electric power source 21 is set so that the electric charge having the same polarity to the electrification polarity of the developer 17 is generated. Accordingly, a chemical latent image is formed on the photosensitive sheet 11, and the developer 17 on the white part of an original, i.e., the part where reflection light is obtained, is copied on the photoconductor drum 23 from the photosensitive sheet 11 and removed. The developer 17 is recovered by a cleaning unit 67.

Title: Production of magnetic recording medium
Inventor: YOSHIDA SHINYA
IPC: C23C14/08
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a process for production for manufacturing a diagonally vapor deposited medium having a higher density and higher crystal orientation property. SOLUTION: Only the deposition chamber 8 is separated in a vacuum chamber 1 in order to increase the energy of vapor deposition particles on a substrate film 2. This deposition chamber 8 is evacuated by another discharge system, by which a differential pressure is generated between the deposition chamber 8 and the inside of the chamber 1 and the energy is applied to the vapor deposition particles by the differential pressure. Further, the directivity of the vapor deposition particles is limited by limiting the width of the opening of the deposition chamber 8 to execute deposition with only the vapor deposition particles from the same direction, by which the structure to enhance the crystal orientability is obtd.  The manufacture of the vapor deposited thin films having the denser structure and the higher crystallinity than those of the conventional media is made possible and the magnetic characteristics of the films are improved.

Title: Data transmission circuit
Inventor: YOKOI YOJIRO
IPC: H04J3/04
Filed: 1993-03-02
Abstract: PURPOSE:To attain transmission of selection information through a data transmission line only by preparing a non-signal period and updating the selection signals every time the data are divided into a prescribed number of pieces at and after the time point when the non-signal period is through. CONSTITUTION:When a selection signal B falls, the output signals of L levels are generated by a monostable multivibrator 4 for a prescribed time. When the generation of output signals of the multivibrator 4 is over, the output signal received from a V/F converter 2 is sent to a transmission line from an AND circuit 5 and supplied to a 1/m counter 6. The counter 6 transmits the overflow signals every time the input signal of the counter 6 is divided into (m) pieces. As a result, an AB counter 3 is set in a count-up state and the selection signals A and B are updated in each count-up state of the counter 3. A multiplexer 1 selects one of input terminals d1-d4 and transmits a data signal. Therefore the selection periods of all channels equal to the periods when (m) pieces of output of the circuit 5 are generated. Thus it is possible to know the selection state at the receiver side.

Title: Carrier for electrophotography and electrophotographic device
Inventor: OGINO TAKESHI
IPC: G03G9/113
Filed: 1993-03-24
Abstract: PURPOSE:To provide a carrier for the electrophotography having easily controllable electric resistance, a low rate of change of the resistance due to continuous printing and excellent durability by using a solvent-soluble electrically conductive polymer as the coating resin on the surface of the magnetic core of the carrier. CONSTITUTION:As for the electrically conductive polymer, polyaniline derivatives such as soluble polyaniline obtained by removing the dopants from a chemical oxidation polymer of aniline, poly-o-methoxyaniline which is provided with solubility in solvents by introducing a substituent to it, etc., can be used. Changes of resistance and triboelectricity of the carrier due to release of the filler and peeling-off of the coating film, etc., can be prevented from occurring by coating the surface of the carrier with the solvent-soluble, electrically conductive polymer. The wear of the conductive polymer itself is not so much since its hardness is comparatively high. Further the resistance of the carrier is easily controllable by selecting the dopant used for the doping and controlling concn. of the dopant, doping temp. and doping time at the time of performing the doping.
