Title: Semiconductor integrated circuit
Inventor: KAWABATA SHOZO
IPC: H03K19/08
Filed: 1990-09-10
Abstract: PURPOSE:To reduce power consumption by constituting the semiconductor integrated circuit with the connection of a compensation circuit interrupting a steady-state through-current flowing to a load logic circuit based on the output signal of a bipolar (Bi) CMOS logic circuit to a Bi CMOS logic circuit or the load logic circuit. CONSTITUTION:Lots of CMOS inverters 2a-2n or Bi CMOS inverters 3a-3n for a load logic circuit are connected to the output terminal of a Bi CMOS inverter 1. Moreover, A CMOS inverter 4 having a smaller load driving capability than that of the Bi CMOS inverter 1 is connected in parallel with the Bi CMOS inverter 1 as a compensation circuit. By such constitution, when an input signal Vin reaches an H level or an L level steady-state, an output signal Vout transits to the voltage level of a power supply Vcc or Vss by the action of the CMOS inverter 4, then no steady-state through-current flows to the next stage CMOS inverters 2a-2n or Bi CMOS inverters 3a-3n.

IPC: G03G15/09
Filed: 1991-09-19
Abstract: PURPOSE: To provide a development unit, provided with a means for transferring a developer to the inside of a developing area in an active mode and taking out the developer from the developing area in an inactive mode. CONSTITUTION: The developer is carried into the developing area 62 by a tubular member 54 and attracted to the surface of the tubular member by a fixed magnet 60. In the active mode, a weak magnetic field is formed in the developing area, the developer is released from the surface of the tubular member and a latent image attracts the developer to it. In the inactive mode, an electromagnet 64 is magnetically excited, so as to reduce the magnetic field gradient in the developing area and the developer is prevented from moving along with the tubular member. The tubular member is rotated in a direction opposite to a rotating direction during the development.  In the magnetically excitated state of the electromagnet, the developer is moved along with the tubular member, so as to be away from the development area, the naked surface of the tubular member is positioned in the developing area, thus the development of the latent image is prevented.
