Inventor: SAITO HIROMOTO
IPC: B65H7/02
Filed: 2002-08-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a detection device, a sheet conveyance device, and an image forming device, capable of detecting a condition (position) even when movable parts such as sheets normally or reversely rotate with a simple structure, and providing cost reduction and high reliability.  <P>SOLUTION: An arm 3 which is brought into contact with an object to be detected is fitted in a hole 4a provided at a filler 4 for shielding a permeation type optical sensor 7. The arm 3 is supported at the hole 4a so as to be oscillated. When the object to be detected is not brought into contact with the arm 3, a protrusion 3b on an opposite side to a part 3a of the arm 3 brought into contact with the object to be detected is brought into contact with and pressed against the filler 4 by a torsion coil spring 5 to stop the rotation. When the arm 3 is rotated in a prescribed direction, the filler 4 rotates as well to switch on the optical sensor 7. When it rotates in a reverse direction to the prescribed direction, the arm 3 only rotates with the hole 4a centered to keep the optical sensor 7 in an OFF condition with the filler 4 kept stationary.  <P>COPYRIGHT: (C)2004,JPO

Title: Fuel supply system of internal combustion engine
Inventor: FURUSAWA SHINYA
IPC: F02M37/00
Filed: 2002-08-27
Abstract: <P>PROBLEM TO BE SOLVED: To solve the following problem: in an internal combustion engine wherein fuel is injected by using a high pressure fuel pump, fuel sometimes leaks from an injector to an internal combustion engine body when the engine is stopped, and deterioration of exhaust emissions is caused when starting the engine.  <P>SOLUTION: If a signal for stopping the internal combustion engine is transmitted to an ECU (S10), the ECU stops the high pressure fuel pump (S12). At this time, a low pressure fuel pump is made to continue its operation. The ECU calculates an injection quantity required to lower a pressure in a high pressure fuel pipe (S14), and sets frequency n of injection of the injector (S16). When the set frequency n is reached (Y of S20), the ECU stops fuel injection and ignition, and stops the lower pressure fuel pump (S22).  <P>COPYRIGHT: (C)2004,JPO
