Title: Electrifier and image forming device using same
Inventor: SHIMURA MASARU
IPC: G03G15/02
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To make an electrifying roller abut on the surface of a photoreceptive drum without causing pressure irregularities and to prevent toner from being firmly stuck to it. SOLUTION: An electrifying roller 40 is formed from a conductive shaft 41 and a conductive elastic body. Projecting parts 41 a at both ends of the conductive shaft 41 are supported by support members 51. Parts of the conductive shaft which are slightly inside the support members 51 are energized toward the photoreceptive drum 11 by means of pressing members 52. The center part of the conductive shaft 41 consequently curves toward the drum 11. Thus, because the abutting part of the electrifying roller 40 is formed into a dummy crown, pressure irregularities are eliminated.

Abstract: PURPOSE:To attain a high-speed access by providing a bisected photodiodes, a rectangular prism arranged so that the optical axis of radiating light is intersected orthogonally with the optical axis of converged light and a wave front converting element. CONSTITUTION:A signal recorded on a recording medium obtains the sum of all the outputs of four areas of two sets of bisected photodiodes 111a and 111b.

That is to say, the diode 111a detects the light-quantity of the half of the luminous fluxes incident on the lens 107 with a central axis as a boundary and the diode 111b detects the light-quantity of the other half. When a convergence point 109 is on a track, there is not the difference between the outputs of the 111a and the 111b and when it is off, the direction and the size of a track-off can get known by obtaining the difference between the 111a and the 111b.

Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To judge the fire-fly state of conductive foreign matter accurately by detecting the partial discharge, wherein at least one generating pattern of the time interval and the amplitude of a partial discharged pulse is classified into two parts. SOLUTION: The detected signal of a partial discharge detector 50 is accepted in an oscilloscope 60 and converted into the discharge pulse. The information is operated and judged in a computer 70, and the presence or absence of the occurrence of fire fly is displayed. The flre-fly phenomenon accompanies two kinds of the discharging phenomena. One is the partial discharge, which occurs at the tip of a conductive torign matter on the side of a grounding tank 20 when the conductive foreign matter 20 reaches a high-voltage conductor 10. Another is the partial discharge, which occurs in the gap between the conductive foreign matter 80 and the high voltage conductor 10.  At the time of the fire flay, two kinds of the patterns of the discharges, wherein the charge time interval is long and the amplitude is large, and the charge, wherein the interval is short and the amplitude is small, appear. Thereafter, when the partial discharge, wherein one generated pattern is classified into two parts, is detected, it is judged that the conductive foreign matter causes the fire fly.
