According to one embodiment, an image forming apparatus includes an endless device, a power supply unit, an electric charge supplementary unit, and an image forming unit. The endless device is rotated. The power supply unit supplies a recording medium on a surface of the endless device with an electric charge. The electric charge supplementary unit supplements the electric charge to the recording medium which is rotated together with the endless device in the state of being attracted to the surface of the endless device by the electric charge provided by the power supply unit. The image forming unit forms an image on the recording medium attracted to the surface of the endless device.

A nonvolatile decision memory unit stores decision data indicating whether data stored in the normal memory cells is true or false. An inversion control circuit sets the inverting signal to a valid level with a predetermined probability. A write circuit writes data having logic which is inverse logic of data to be rewritten to the normal memory cells and writes decision data indicating false to the decision memory unit when the inverting signal indicates a valid level. Since inverse data is rewritten at a predetermined frequency, an imprint is prevented when a read operation is executed repetitively. Moreover, since frequent repeating of reverse polarization of the ferroelectric capacitor due to a rewrite operation is prevented, deterioration of the ferroelectric capacitor due to reverse polarization is minimized. Thus, occurrence of the imprint and deterioration of characteristics in the ferroelectric capacitor is prevented, and the reliability of the ferroelectric memory is improved.

A compound semiconductor integrated circuit is adapted to provide an interface with respect to an internal circuit which is driven by first and second power source voltages and operates responsive to a logic signal having a predetermined logic level which is different from an emitter-coupled logic level. The compound semiconductor integrated circuit includes an input circuit part which is driven by the first and third power source voltages and receives an input logic signal having the emitter-coupled logic level, and an output circuit part which is driven by the first and second power source voltages and converts an output signal of the input circuit part into a signal having the predetermined logic level. The second power source voltage is lower than the first power source voltage. The third power source voltage is different from the second power source voltage and is lower than the first power source voltage. The output circuit part supplies an output thereof to the internal circuit.

A cavity resonator coupling type power distributor/power combiner can be used as a distributing amplifier or a combining unit. A first cavity resonator, having a single coupling terminal, and a second cavity resonator having a plurality of coupling terminals, are coupled by a coupling window or a coupling rod. As a result, a wide bandwidth of microwave electric power can be distributed or combined.
