Title: Electrostatic image developing method and image forming method
Inventor: MATSUBARA AKITOSHI
IPC: G03G13/08
Filed: 1987-02-10
Abstract: PURPOSE:To increase an image density and to improve image quality by applying a DC bias and AC bias to a developing space at the time of bringing a developer layer deposited on a developer carrying body into contact with an electrostatic latent image formed on the surface of a latent image carrying body to develop said image. CONSTITUTION:The developer layer 23 deposited on the developer carrying body 11 is brought into contact with the electrostatic latent image formed on the surface of the latent image carrying body 10, by which the latent image is developed. Sticking of toner particles to the non-image part of the latent image carrying body 10 is suppressed by applying the DC bias to the developing space 24. The toner particles in the developer layer 23 are subjected to microoscillation according to the frequencies of the AC bias by applying the AC bias to the space 24. Selective adhesiveness of the toner particles to the electrostatic latent image is, therefore, exceedingly improved at the adhesion thereof to the non-image part is suppressed. The toner image having the high image density and the good image quality without having fogging is thereby formed.

Title: Power source circuit of iil circuit
Inventor: NISHIJIMA HIDEO
IPC: G05F1/56
Filed: 1983-02-23
Abstract: PURPOSE:To reduce power consumption greatly by controlling the propagation delay time of every gate accurately and supplying minimum electric power corresponding to the necessary operation frequency of an IIL circuit from an efficient switching regulator to the IIL circuit. CONSTITUTION:A voltage-controlled oscillator 16 is constituted by connecting annularly three IIL inverter circuits consisting of PNP transistors(TR) 10-12 and NPN TRs 13-15 in combination. Further, a resistance 21, TR24, diode 25, coil 26, and capacitor 27 constitute a switching regulator. Then, the propagation time of the IIL inverter decreases by the amount of a current applied to a terminal 6 as the power consumption increases. When the oscillation frequency of the oscillator 16 is, for example, low, the conduction period of the TR24 is longer than the cutoff period and the DC voltage at the terminal 6 rises. Consequently, the injector current of the IIL inverter increases to shorten the propagation delay time and the oscillation frequency increases to perform stable oscillation at some frequency.

Abstract: PURPOSE:To form a two-dimensional quantum structure, by laminating semiconductor layers on the side surface of a semiconductor thin film layer wherein semiconductor thin films of different composition are subjected to etching after laminating. CONSTITUTION:After a GaAs buffer layer 4 is grown, an AlGaAs thin film layer 2 and a GaAs thin film layer 1 are alternately formed, and then a GaAs layer 3 is grown.

On this uneven side surface, an AlGaAs thin film layer 8 and a GaAs thin film layer 7 whose band gaps are narrower than that of the thin film layer 2 are alternately grown, and finally a GaAs layer 9 is grown. A two-dimensional quantum structure is formed thereby, and characteristics of a photoelectron device can be improved.

Abstract: PURPOSE:To enable the immediate detection of the stalling of a motor by providing a limiter detector and a deviation detector in a current reference circuit and controlling the motor in response to the detected results of both the detectors, thereby reducing the power loss. CONSTITUTION:When an AC motor is stalled, a voltage detection signal VS is lowered, and the output of a voltage controller 9 reaches a limiter value and hence a current limiting value.

Accordingly, it is detected by a deviation detector 33. The contacts 46, 47 of a stall detector 45 are closed by the detection of both values to detect the stall of the AC motor, and the power source circuit is opened or the gate of a converter 2 is interrupted by the detector 45.
