Filed: 1995-02-10
Abstract: PURPOSE: To eliminate transfer missing and to enhance printing quality by impressing a bias voltage on a transfer roller only when a paper is interposed between an intermediate transfer belt and a transfer roller. CONSTITUTION: The transfer roller 29 is made to abut on the intermediate transfer belt 16 by a transfer roller abutting cam 28 behind the rotation of a resist roller. Thereafter, the leading end part of a paper 23 is detected by the light emitting element 37 and the light receiving element 38 of a paper end detecting part, and the effect is transmitted to a transfer bias control part. After a fixed period passes after the transfer roller 29 is made to abut on the intermediate transfer belt 16, the leading end part of the paper 23 reaches a position where the belt 16 abutts on the transfer roller 29. Then, the transfer voltage is impressed on the transfer roller 29 after the fixed period.  And also, the trailing end part of the paper 23 is detected by the light emitting element 37 and the light receiving element 38 of the paper end detecting part, and the effect is transmitted to the transfer bias control part. And after the printed area of the paper 23 passes, and after a fixed period passes, the transfer bias voltage to be impressed on the transfer roller 29 is turned off.

Title: Removal of foreign matters adhered to packing material
Inventor: SUYAMA KOUHEI
IPC: B01D53/86
Filed: 1983-02-16
Abstract: PURPOSE:To effectively remove foreign matters adhered to a packing material, in an apparatus having a packing material comprising an exhaust gas denitrating catalyst, by partially blocking the inflow of a fluid into the packing material by forming a gas curtain while increasing the flow speed in the unblocked part of said packing material. CONSTITUTION:Air pipes 4 each provided with air jet parts 4' so as to divide a packing material are arranged in a reactor 1 and compressed air is injected from the air jet parts 4' while flowed to the air pipes 4 to form an effective air curtain at every stage. When air is injected from a part of the air pipe 4, said air is formed into the air curtain 4 and a fluid flowing through the reactor 1 is blocked at that part to block the flow of the fluid into the packing material 2 at the part where the air curtain 5 is formed and the fluid is flowed through the other part of said packing material 2. At this time, because the fluid is passed through the packing material having a narrower cross sectional area than ever, the flow speed of the fluid is increased and the foreign matters adhered to the packing material are removed to the downstream side.

Filed: 1978-03-01
Abstract: PURPOSE:To complete the essential function of the system at any time by outputing the system enable signal when the source voltage exceeded over predetermined level after throwing-in while outputing the system disable signal before the source voltage drops below predetermined level after interruption. CONSTITUTION:At the initial stage of throwing-in of power source, transistor 18 is turned off while the transistor 24 is turned on and the system control sigal Sc from the terminal 25 is low. While when the voltage reaches to Zener voltage Vz of Zener diodes 13, 14, the transistor 21 turns on and Sc inverts to high level at the time point t1 time later than that where Vz starts to be constant. After interruption of power source Sc is inverted to low and after elapsing the time interval t2 Vz starts to drop. Consequently the system functions after the voltage reached to constant level and its function can be completed even if the system has started functioning after the power interruption.

Filed: 1988-02-05
Abstract: PURPOSE:To prevent an image from shifting in position and color by nearly equalizing the coefficients of heat expansion of a mount for a galvanomirror and a laser light reflecting plate which is fixed on the mount. CONSTITUTION:The mount 31 for the galvanomirror 30 and the laser light reflecting plate 32 are nearly equalized in coefficient of heat expansion. If the laser light reflecting plate 32 fixed to the galvanomirror mount 31 which determines the position of a laser beam is strained thermally, an image formed on a liquid crystal element becomes different in position. For the purpose, the galvanomirror mount 31 and the reflecting plate 32 fixed thereto are equalized in coefficient of heat expansion to enable the galvanomirror mount 31 and reflecting plate 32 to expand and contract equally even if the ambient temperature varies. Consequently, the image is prevented from shifting in position and color.
