Filed: 1986-03-28
Abstract: PURPOSE:To prevent all of ground fogging, ground staining, and ghost image formation from being caused by performing magnetic brush development by using a developer formed by mixing powder for development with powder for cleaning as powder other than toner. CONSTITUTION:A developing device uses a developer obtained by mixing the powder for development with the powder for cleaning as powder other than toner. The powder for development is low-resistance magnetic carriers and charges having polarity reverse to that of an electromagnetic latent image are implanted to the surface; and an electrode is formed nearby a photosensitive body to generate an intense electric field between the electrode and latent image, and then the latent image on a photosensitive body is visualized with sufficient image density. The powder for cleaning are high- resistance carriers, so part of toner sticking on the surface of the photosensitive body is attracted to a latent image boundary part and other toner is attracted onto a developing sleeve. Those toner particles leave the surface of the photosensitive body and charges having polarity reverse to that of the toner are left on the surfaces of the high-resistance carriers locally and never discharged unless leaking to the developing sleeve surface. Therefore, the transfer remaining toner at the time of repetitive use is guided by the opposite-polarity charges on the high-resistance carrier surfaces and attracted and recovered efficiently and securely.

Title: Current feedback type transistor driving circuit
Inventor: HIRANABE TETSUJI
IPC: H02M7/537
Filed: 1981-05-07
Abstract: PURPOSE:To limit the increase in the driving current of a transistor in case a load current is increased by comparing the voltage amplitude of a load resistor with a reference voltage and supplying a voltage exceeding the reference voltage to the coil of a conversion transformer. CONSTITUTION:A current flowing through a load L and hence the collector current of a transistor Q is also flowed through the primary coil N1 of a compensating transformer T2. A voltage generated at the secondary coil N2 of the transformer T2 is applied to a resistor R. A reference voltage VR determined by a zener diode ZD is compared with a voltage across the resistor R. When the voltage across the resistor R exceeds the reference voltage VR, the zener diode ZD is conducted, and the voltage exceeding the reference voltage is applied to the coil N3 of a transformer T1. The voltage induced by the coil N2 by the voltage of the coil N3 has opposite direction to the direction of the voltage induced at the coil N2 by the voltage of the coil N1, and accordingly the increase in the driving current at the base of the transistor Q can be suppressed.

Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To enable constituting the structure of a guard ring at intervals which anticipates the dispersion in masks, even when silicon carbide is used. SOLUTION: P<-> -type well regions 21 in the outer peripheral region of a cell region is formed at higher concentration than that in P<-> -type silicon carbide base regions 3 of a MOSFET in the cell region. Thus, the intervals in the P<-> - type well regions 21 can be widened, thereby enabling the mask dispersion to be anticipated in the expanded intervals. More specifically, the P<+> -type silicon carbide base regions 3 and the P<-> -type well regions 21 are formed using different masks. At this time, by taking the mask slippage caused by the different masks into consideration, a junctioning P<-> -type region 20 is arranged between the P<+> -type silicon carbide base regions 3 and the P<-> -type well regions 21.  Through these procedures, since the overlapping of the P<-> -type well regions 21 with the base regions 3 can be avoided even if a mask slippage occurs, thereby enabling the P<-> -type well regions 21 to be sustained in floating state.
