Title: Cleaning device and image forming apparatus
Inventor: NAKAYAMA TAKAHIRO
IPC: G03G21/10
Filed: 2004-06-14
Abstract: <P>PROBLEM TO BE SOLVED: To easily carry out cleaning to remove a foreign matter sticking to a contact portion of a cleaning blade without requiring labor.  <P>SOLUTION: A cleaning device 14 cleans the peripheral surface of an image bearing member 5 through a brush roller 23 which rotates while keeping a brush 23b in contact with the peripheral surface of the image bearing member 5 and a cleaning blade 24 whose contact portion 24a is kept in contact with the peripheral surface of the image bearing member 5. When the cleaning blade 24 is moved by a contact-release mechanism 26 to a release position where the contact portion 24a is released from the image bearing member 5, the contact portion 24a moves to a position where it comes in contact with the brush 23b of the brush roller 23, accordingly a foreign matter sticking to the contact portion 24a can be removed by interference of the brush 23b of the rotating brush roller 23 with the contact portion 24a, whereby cleaning of the contact portion 24a can easily be carried out without requiring labor.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Title: Valve timing varying device and valve timing regulating device
Inventor: SHIMAZAKI SHINOBU
IPC: F01L1/34
Filed: 2004-06-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a valve timing varying device and a regulating device, which can suppress rotation fluctuation of the cam shaft of an internal combustion engine without adding control for rotation fluctuation countermeasure to control of the output of an electric motor.  <P>SOLUTION: A valve timing can be advanced or delayed since the desired number of rotations can be realized for a cam shaft 6 interlocking as a result of torque being generated at a turbine impeller 24b. Since the cam shaft 6 and the electric motor 22 are interconnected by a torque converter 24 through oil, torque fluctuation on the cam shaft 6 side accompanying with valve drive is not transmitted directly to the electric motor 22 side, and on the electric motor 22 side, there is no need to apply control for rotation fluctuation countermeasure. Besides, since torque fluctuation occurring to the cam shaft 6 side is absorbed by a damper effect at the turbine impeller 24b, rotation fluctuation at the cam shaft 6 is suppressed.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a thermal head which can improve the operation characteristic of the thermal head as much as possible.  <P>SOLUTION: In a state while an intermediate layer 3 which has a coefficient of thermal expansion C3 between a coefficient of thermal expansion C1 of a glaze layer 2 and a coefficient of thermal expansion C2 of a heating resistor layer 4 (for example, C2<C3<C1) is interposed between the glaze layer 2 and the heating resistor layer 4, the heating resistor layer 4 is rapidly heated (RTA::Rapid Thermal Annealing). The crystallinity of polycrystalline silicon which constitutes the heating resistor layer 4 is improved on the basis of the thermal relaxation action. Moreover, even if an internal stress is generated as a result of thermal deformation of the glaze layer 2 at the time when the heating resistor layer 4 is heated, the intermediate layer 3 is thermally and physically deformed in accordance with the deformation of the glaze layer 2, whereby the internal stress is relaxed. The internal stress is accordingly prevented from reaching the heating resistor layer 4. Thus the heating resistor layer 4 is prevented from being thermally and physically excessively deformed.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
