Title: Switching regulator
Inventor: ABE KIMIHITO
IPC: H02M3/338
Filed: 1980-06-13
Abstract: PURPOSE:To enhance utilization factor of the main transformer of a switching regulator by a method wherein the first primary winding of the main transformer being provided with a switching element in the input side is made to supply electric power only to a control circuit and the second primary winding is made to supply to both a load and the control circuit. CONSTITUTION:When a capacitor C1 is charged by an electric power source Ein through a resistor R1, a transistor Tr1 is ignited. The capacitor C1 is charged in the opposite direction by a base current IB, the transistor Tr1 is made to TURN-OFF, and by repetition of this action, the voltage of a capacitor C3 to act as an auxiliary electric power source is made to rise sufficiently. When the transistor Tr1 performs self-oscillation at this time, because a voltage of backward polarity is generated in the secondary winding N2 of the main transformer T1, no output is made to rise. When a transistor Tr2 is driven by a pulse duration control signal sent from an output detecting circuit 2 and a control circuit 1, the primary winding N12 is excited in the polarity according to ON-duty of the signal thereof to make an output voltage in the secondary winding N2 to rise.

Title: Image forming device
Inventor: KOGA YOSHIRO
IPC: G03G15/09
Filed: 1989-03-30
Abstract: PURPOSE:To reduce a cost by making the space length of a part where a latent image carrier and a toner conveying body are closest to each other shorter than the maximum height of toner layers on the toner conveying body and longer than the minimum height of the layers. CONSTITUTION:The space length of the part where the latent image carrier 1 and the toner conveying body 8 are closest to each other is made shorter than the maximum height of the toner layers 11 on the toner conveying body 8 and longer than the minimum height of the layers. Therefore, simultaneously when a solid image part and a line image part are developed in the contact condition of an magnetic brush and the latent image carrier 1 and toner made to adhere to a nonimage part is scraped away at a part at which the magnetic brush is separated from the latent image carrier 1, the solid image part is developed in a non-contact condition. Hereby, excessive toner adhesion to the line image part caused by an edging effect is reduced. Thus since an alternative high voltage electric source is not used, a malfunction due to noise is eliminated and a device cost can be reduced.
