Title: Method and circuit for preventing forward bias of parasitic diode in integrated circuit
Inventor: TOOMASU AARU DOUSHIYAZO JIYUNI
IPC: H03F1/08
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent a diode on the collector substrate of an integrated circuit from being biased in the forward direction. SOLUTION: In a method and circuit for preventing a diode D1 on the collector substrate of an integrated circuit from being biased in the forward direction, a load which is driven by means of a bipolar transistor Q11 is offset by such a reference voltage as the grounding voltage of the circuit by a variable voltage offset. The difference between the collector voltage VC of the transistor Q11 and the reference voltage is detected and the base current IB of the transistor Q11 is changed in accordance with the detected difference so that the base current IB may become zero when the collector voltage VC is equal to the reference voltage. Therefore, when the emitter voltage of the transistor Q11 is lower than the reference voltage, the corrector current IC of the transistor Q11 becomes less than β times the base current IB and the diode D1 is not biased in the forward direction.

IPC: G03G15/047
Filed: 1987-05-16
Abstract: PURPOSE:To form an image having a desired density by changing the quantity of light of a prescribed LED element group of one pitch width. CONSTITUTION:The photosensitive layer on the surface of a drum 61 is sensitized and electrified while passing eraser lamps 62 and 64 and charging chargers 63 and 65, and is exposed to the image light from an optical system 5 to form an electrostatic latent image. Toner is stuck to this latent image by a developing device 66 and is transferred onto a transfer form by a transfer charger 67. Currents supplied to LED element groups of a long pitch and a short pitch of an inter-image part eraser unit 4 are varied. For example, when the supply current is reduced, the optical output of LEDs is reduced and the electrification potential on the photosensitive body is reduced, and toner is stuck in accordance with this reduction. Consequently, an image tone is arbitrarily set.
