Title: Image forming device
Inventor: NAMIKI KAZUHIKO
IPC: G03G15/01
Filed: 1995-02-22
Abstract: PURPOSE: To prevent deviation in position of a transfer image caused by disparity in stretching of a belt derived from a difference in tension of the belt between when in contact and when out of contact, by restraining the difference in the expansion of the intermediate transfer body between when in contact and when in uncontact with a photoreceptor within a specified value. CONSTITUTION: A switch back system is adopted for transferring the image to the intermediate transfer belt 11, and the intermediate transfer belt 11 is separated from the photoreceptor at the time of non-transferring to the intermediate transfer belt 11, moved in the forward direction or the backward direction for aligning toner images, and then held in contact with the photoreceptor at the time of transferring so that the transfer of image is performed. Then, in the tension providing part of the intermediate transfer belt 11, the tension is provided by holding the tension roller 23 in press contact with the intermediate transfer belt 11 by a pressure spring 40. In the meantime, the tension difference between when in contact and when out of contact is restrained so as to be within ±IN (newton). This is performed by adjusting a pressurizing force by such as an eccentric cam 36 and the pressure spring 40.

IPC: H03H9/72
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of insertion loss via a simple circuit constitution by inserting a single terminal paired SAW(surface acoustic wave) resonator and a capacitor in series between the connection point of two parallel SAW filters and a 1st SAW filter.

IPC: H04N5/59
Filed: 1984-03-28
Abstract: PURPOSE:To eliminate the blind sector of luminance restricting action by clamping the detected voltage of anode current of a CRT to the voltage corresponding to luminance regulating voltage, and setting this voltage to the driving voltage of an output transistor. CONSTITUTION:Anode current detection voltage VA is generated in the detecting end of a resistance 12 for anode current IM detection of a CRT. Luminance regulating voltage VB of a luminance controlling circuit 3 is supplied from a variable resistance 7 to which power source VCC1 is applied. Voltage VB is supplied to the emitter of a transistor TR5 for luminance restriction, and voltage from the variable resistance 7 is applied to the base of a TR29 that forms voltage VD corresponding to the voltage VB. Voltage VA is clamped to the voltage VD by a clamping diode 17 and applied to the emitter resistance 22 of a TR4 as the driving voltage of the output TR4. Thus, operation characteristics changing from non-restricting operation of regular luminance to restricting operation are not accompanied by the state of no control, and elimination of the blind sector of luminance restricting action becomes possible.
