Title: Drum unit and earth plate used for drum unit
Inventor: KASHIWAGI NOBUYUKI
IPC: G03G21/00
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent the contact failure between an inner circumferential contact part and a shaft pin by preventing the deformation of a plate base by a reinforcing part provided on an earth plate. SOLUTION: A drum crude pipe has opening parts on both end parts, and thin flange fitting parts are formed in a prescribed length on the opening ends. Reinforcing parts 52 protruded in the same direction as contact pieces 46, 47 are provided on the circumferential edge of the through-hole 43 of a plate base 41. The reinforcing parts 52 reinforce the bending strength in the periphery of the through-hole 43 and prevent the plate base 41 from being deformed by receiving a stress. When a flange member having the earth plate 40 mounted thereon is inserted to the opening part of the drum crude pipe, thus, the contact of the contact pieces 46, 47 with a shaft pin can be surely kept.  In this case, a claw member 44 is brought into contact with the inside surface of the flange fitting part of the drum crude pipe and elastically deformed to electrically conduct the earth plate 40 to the drum crude pipe.

Abstract: PURPOSE:To eliminate the deterioration of the collector-emitter breakdown strength by using a switching means which sets the base of a 1st npn transistor under a non-open state based on the detecting result of the OFF state of said npn transistor where a constant current source is connected to the collector. CONSTITUTION:A switching circuit 4 consisting of the transistors (TR) Q11-Q13 and a constant current source 3 is added to a conventional circuit. Both TRs Q12 and Q13 form a current mirror circuit and a constant current I3 is supplied from the source 3. When a 4th TR Q11 is turned on by an external control signal, all currents of the source 3 flow to the collector of the TR Q11. Then the 1st npn TR Q1 is turned off. As a result, 2nd npn Trs Q2-Q6 are all turned off. While the base of the TR Q1 is set under a non-open state by the circuit 4. Thus it is possible to keep the collector-emitter breakdown strength of an npn TR Q at a high level.
