Title: Fixing roller and manufacture thereof
Inventor: MATSUO MINORU
IPC: F16C13/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a fixing roller in which the flocculation of a phase transition heating material is not caused even when a melting and a crystalizing cycle are repeatedly executed and to realize the easy manufacture thereof by providing it with a phase transition heating layer obtained by dispersing grains of the phase transition heating material in a binding agent and forming the grains by a vacuum-deposition. SOLUTION: A phase transition heating layer 5 is formed on the outside circumference of a core bar 2. The layer 5 is obtained by dispersing the fine grains 3 of a phase transition heating material generating heat energy at the time of the transition of a phase to crystalline from amorphous in a binding agent 4 such as polyimide. Then, the grains 3 are formed by a vacuum- deposition. In order to disperse the vacuum-deposited grains 3 of the phase transition heating material in the binding agent, it is preferable that the agent 4 and the grains 3 being the phase transition heating materials are alternately deposited. Moreover, the monomer of polyimide is good as the agent 4. A method for polymerizing the monomer after the grains 3 of the phase transition heating materials are uniformly covered with the monomer by deposition, is good.

Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of maintaining the excellent printing quality over a long period and easily performing multiple transfer by composing at least a part of the surface part of a transfer drum of an elastic body. SOLUTION: The transfer drum 3 is formed into cylindrical shape consisting of a conductive pipe stock made of aluminum, etc. The surface layer thereof is composed of the elastic body 1 consisting of a high polymer material. Moreover, spacers 5 are fitted over whole periphery on the several vicinity on either end in the shaft direction of the transfer drum 3. Since the surface of the spacer 5 is held in butting to the surface of a photoreceptor as the image carrier, respective shaft of the photoreceptor and the transfer drum 3 is made possible to maintain the parallel positional relation. As a result, a distribution in the transfer drum shaft direction of the maximum deformation amount of the elastic body in the nip section becomes uniform.  Furthermore, the elastic body 1 is fixed by a screw on the transfer drum 3 surface in a state of being affixed to an aluminum sheet as the elastic body mounting sheet 23.

Title: Power converter
Inventor: KIMOTO KENICHI
IPC: H02M7/5387
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a power converter which converts power from a direct-current power supply into an alternating current and interfaces it with a system, without the use of an insulating transformer, and reduces the occurrence of leakage current. SOLUTION: When a three-phase, three-wire system with one wire grounded is connected, the intermediate point between two series capacitors 19, 20 is connected with the wire at ground potential of the three-phase, three-wire system to control the current of three sets of half-bridge inverters 4-6. Through the wire used to connect the intermediate point between the two series capacitors 19, 20 with the wire at ground potential of the three-phase, three-wire system, a current equivalent to the difference between the current obtained by summing the currents passed through the other two phases and reversing the polarity of the sum, and the output current of the half-bridge inverter 5 connected with the phase, is flowed. However, the intermediate point between the capacitors 19, 20 is fixed at the ground potential of the system.  When the capacitance of the capacitors 19, 20 is sufficiently large therefore, the voltage fluctuation in the capacitors 19, 20 is reduced and the potential of a direct current part is fixed at the ground potential. Thus leakage current due to oscillation of the direct-current parts can be reduced.

Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To prevent a data transmission rate from decreasing by performing microprocessor control(MPC) transfer after direct access memory(DMA) transfer without interrupting the DMA transfer when a PCI bus is occupied for a certain time by the MPC transfer. SOLUTION: When the DMA transfer is performed and a bridge circuit 7 receives an MPC transfer instruction from an MPC 2 before the DMA transfer ends, a PCI monitor circuit 8 decides whether or not the PCI bus 6 is occupied for a certain time by the MPC transfer. When it is decided that the PCI bus 6 is not occupied for the certain time, the precedent DMA transfer is interrupted. After the MPC transfer is performed to the end, the DMA transfer is restarted. When it is decided that the PCI bus 6 is occupied for the certain time, the precedent DMA transfer is carried on without being interrupted. Then the MPC transfer is performed after the DMA transfer ends.
