IPC: G03G15/06
Filed: 1990-11-06
Abstract: PURPOSE:To prevent a toner from being transferred wastefully onto a photoconductor so as to prevent wasteful consumption of the toner, contamination of the inside of a device and imperfect cleaning, etc. by switching a bias applied to a developing means to a non-develop bias when the photoconductor is not normally charged. CONSTITUTION:If some abnormality arises in a main charger 12 on developing, a current (i) flowing through an operation check line is increased. As a result, a voltage R2/R1 (i) is raised to more than reference electric potential EREF and then the output of a comparator 18 is reversed. The output of the comparator 18 controls a changeover switch 24 and when the main charger 12 is operated normally the bias potential of a developing roller 22 is set at EDEV-500V and when the current (i) flowing through the operation check line is increased to above a predetermined value decided by the reference electric potential EREF the main charger is switched to ENON(+100V) side which is positive electric potential. Thereby a negatively charged toner is held on the developing roller 22 and wasteful transfer of the toner onto a drum 20 is prevented.

Title: Cover opening device for taking cartridge out of film unit with lens
Inventor: KOGANE MIKIO
IPC: G03B17/28
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of expressly performing film winding operation with manual labor and to simplify work by automatically winding all the photographic film inside a cartridge by allowing a film winding mechanism to rotate a winding knob in a film winding direction after a film unit is held by a holding mechanism. SOLUTION: When an operation lever 41 is rotated from a position A to a position B, the film unit 1 is held by the holding mechanism and a shutter button is depressed by a shutter depressing mechanism. When the lever 41 is rotated from the position B to a position C further, a cover opening mechanism rotates a hook pawl 42 to the position of a specified insertion angle. When the lever 41 is rotated to the position C, the film winding mechanism rotates the winding knob in a film winding direction. When the lever 41 is separated from the position C, a winding knob mechanism stops the winding of the film. When the lever 41 is rotated to the position B, thereafter, the pawl 42 is inserted in the notched part of the film unit 1 by the cover opening mechanism, and then a bottom cover 23 is opened.

Title: Driver circuit
Inventor: SHUDO HIDEKI
IPC: H04L25/49
Filed: 1989-11-20
Abstract: PURPOSE:To reduce undershoot of an output pulse by short-circuiting a secondary side of a pulse transformer so as to avoid high impedance state. CONSTITUTION:When no reference voltage is fed to a pulse transformer 10, the secondary side terminal of the pulse transformer 10 reaches a high impedance and in this case, a short-circuit means 30 short-circuits the secondary winding of the pulse transformer 10 for a prescribed period after the reference voltage interrupt is started. Thus, just after the application of the reference voltage to the pulse transformer 10 from a switch circuit 20 is interrupted, the charge stored in line capacitor C is discharged momentarily via the short- circuit means 30. Thus, the attenuation vibrating state is avoided.

Abstract: PROBLEM TO BE SOLVED: To make sure of attachment of wire netting and improve work execution efficiency by dividing and fixing a supporter which has a slit at the tip and a flat lock piece at the head, into an existing concrete skeleton, when attaching the wire netting for thickening and reinforcement. SOLUTION: A supporter A equipped with a flat lock piece 11 projecting in the direction crossing an axis at right angles is driven into the intersection of a wire net 2, and the wire net 2 is fixed to the existing concrete skeleton 1 by the lock piece 11. Uneven parts are made on the surface and rear of this lock piece 11 so as to prevent the slip from the wire net 2, and improve the adhesion of mortal. After driving of the supporter A, a driving pin 12 is driven into the supporter A to open the slit at the tip of the supporter body 10 so that the supporter A may not come out. Mortal is placed on the wire net 2 so as to thicken and reinforce the concrete skeleton 1. In this case, resin mortal or the like can be used according to the degree of the reinforcement. Hereby, the reinforcement can be ensured.
