Title: Paper feeding device for image forming device
Inventor: HAYASHI SHIGEKI
IPC: B65H3/06
Filed: 1988-04-30
Abstract: PURPOSE:To prevent the generation of copying deflection by installing a sensor in a passage for feeding paper onto a resisting roller through a U-shaped guide from a paper feeding roller and ON/OFF-controlling the revolution of the paper feeding roller according to the slack of the paper sheet detected by the above- described sensor. CONSTITUTION:A paper sheet P supplied from a paper feeding roller 3 is transported onto a resisting roller 5, guided by a U-shaped guide 4. The revolution speed of the paper feeding roller 3 is set larger than that of the resisting roller 5. When the slack of the paper sheet P increases, and the paper sheet P contacts a resisting part detecting switch SW1, the revolution of the paper feeding roller 3 is suspended. When the slack of the paper sheet P reduces, and the P2 and P3 states are generated, the paper sheet contacts a slack quantity detecting switch SW2, and the paper feeding roller 3 is revolved. When the paper sheet P is put into the P1 state, the paper feeding roller 3 stops. Therefore, a resisting roller 5 is prevented from the load variation, and the generation of the copying deflection is prevented.

IPC: G03G15/04
Filed: 1987-05-01
Abstract: PURPOSE:To prevent light from being incident on a photosensitive body as stray light by forming at least one mirror which has a reflecting surface in a region except the end part of a transparent mirror main body in a subscanning direction. CONSTITUTION:Return mirror 58 and 59 are respectively structured so that a reflecting surface 87 is formed in the region except the subscanning-directional end part of the transparent mirror main body 86.

Title: Liquid pressure control device for circuit breaker
Inventor: TAKAGI HIROKAZU
IPC: H01H33/30
Filed: 1988-05-06
Abstract: PURPOSE:To enhance the reliability of a circuit breaker by accommodating a spool valve in a slidable case, and installing flow control valve on the way of high pressure piping so that a valve piston decreases the flow path area of the high pressure piping with motion of the spool valve. CONSTITUTION:When a shutoff command is given, a piston 4 commences a motion to the right. At this time, a lever 17 rotates with motion of a rod 2 coupled with the piston 4 so as to drive a spool valve 14 to the right through a valve rod 14b. Because valve piston 14a decreases the flow path area of a high pressure piping 7 after movement of the valve 14 to a certain degree, the amount of supplied oil to a compression chamber 5a is dropped. As a result, the piston 4 is decelerated and stopped smoothly even though there is no damping action at the finish end of stroke in the damper chamber. This provides possibility of removing a damper chamber to be formed at the finishing time of the piston motion and suppressing pressure rise at the time of damping to ensure reliability of a packing 12 its sealing performance without causing its deformation.
