Title: Image forming device
Inventor: SAITO MASUAKI
IPC: G03G21/14
Filed: 1995-02-23
Abstract: PURPOSE: To always output a high grade image even in such a state that the triboelectrification of toner is reduced, and to prevent the scattering of the toner by setting a developing sleeve driving speed at the time of starting an image device at a specified ratio or below of driving speed at the time of forming an image, when an image forming device is in a stopped state for a specified time or more. CONSTITUTION: After the lapse of 8 hours or more after a power source is turned off, nothing is stored in memory. At this time, it is considered that the toner on an image sleeve 2 has lost the triboelectrification by a natural discharge, because a developing device 12 is left standing, so that the developing sleeve 2 is rotated at a reduced speed, to start the developing device 12. At this time, the driving speed of the developing sleeve 2 at the time of starting the developing device 12 is made half as much or less as the driving speed at the time of forming the image. Thus, voilent force is not exerted even on the toner which is low in triboelectrification and small in force held by the developing sleeve 2 and the toner in never scattered in the image forming device.

Title: Driving method for plasma display panel
Inventor: OKAJIMA TETSUJI
IPC: G09G3/288
Filed: 1990-03-08
Abstract: PURPOSE:To decrease a driving voltage while maintaining the high light emission efficiency of short-pulse driving by specifying the waveform of a voltage which is applied between electrodes. CONSTITUTION:An impulsive voltage applied to the AC type plasma display panel which causes discharge between the electrodes 9 to generate plasma 12 and excites a phosphor 14 with ultraviolet rays by the plasma to obtain visible light 17 is lowered before the discharge stops by itself to stop the discharge. At this time, the pulse is lowered to stop the discharge and then voltage pulses for generating wall charges by attracting charges remaining in a space to an insulating layer 11 are applied to lower the driving voltage while the merit of the high light emission efficiency of the short-pulse driving method is left. Consequently, the low-voltage driving is realized while the high light emission efficiency of the short-pulse driving is nearly maintained.

Title: Optical modulation device
Inventor: NODA ARIHIDE
IPC: G02F1/01
Filed: 1995-03-17
Abstract: PURPOSE: To provide an optical modulation device capable of maintaining an operating point at a stable point even though a temp. change and a secular degradation. CONSTITUTION: An optical mudulator 23 intensity-modulates the output light of a laser diode 21 by a madulation signal in which the sine wave signal outputted by a low frequency oscillator 15 is superposed. The output light is changed into a voltage signal and then the frequency component of the sine wave signal is extracted in a band-pass filter 12. The extracted sine wave is amplified by a variable gain amplifier 11 and a bias voltage is changed based on the phase difference between the phase and the phase of the sine wave signal outputted by the low frequency oscillator 15 so that the operating point becomes a stable point. The variable gain amplifier 11 changes its amplification gain so that the peak value of the extracted sine wave signal becomes the voltage equal to or smaller than the allowable input voltage of a phase detector 14.  Since the signal exceeding the allowable value is not inputted even though the temp. change, etc., occur, the phase comparison is accurately performed and the operating point is maintained at the stable point.
