IPC: G03G21/16
Filed: 1989-03-28
Abstract: PURPOSE:To stably place a photosensitive body without turning by connecting both side plates, which bear the photosensitive body with a stay, and allowing a part of both side plates projecting from the outer peripheral area of the photosensitive body. CONSTITUTION:A holder 28 of the drum-like photosensitive body 13 is composed by connecting both side plates 34 possessing a pair of leg parts 33 with the stay 35 serving also as a grip.

Title: Method for measuring sharpness
Inventor: ADACHI MASAHIRO
IPC: G01N21/892
Filed: 1986-04-04
Abstract: PURPOSE:To make automatic measurement with always high accuracy by detecting the fluctuation rate of the difference in the photodetecting position of two line sensors by the 'waving' generated from the slight partial deflection of reflected slit light by the ruggedness or the like of a surface to be measured when slit light is projected to the surface to be measured thereby obtaining the data indicating the sharpness of the surface to be measured. CONSTITUTION:A slit light source 2 which generates the laser slit light Ls and the two line sensors 3, 4 are disposed at a prescribed angle to a measuring instrument for measuring the shapness of the surface 1a to be measured such as painted surface of a panel 1. The reflected slit light Ls' of a beam of the slit light Ls projected from the slit light source 2 to the surface 1a to be measured is detected by the 1st and 2nd line sensors 3, 4 spaced from each other and disposed in parallel with each other in such a manner that detection lines 3a, 4a by a photodetector array intersect respectively with the reflected slit light Ls'. Then the waving generated on the images on the sensors 3, 4 by the reflected slit light Ls' by the slight ruggedness on the surface 1a projected with the slit light Ls is larger as the sharpness of the surface 1a is poorer.

Filed: 1982-05-06
Abstract: PURPOSE:To stabilize the fuel injection characteristic and spark advance characteristic of a fuel injection pump by a constitution wherein an actuating member actuating a rotary lever with a pinion gear constantly in one direction of a timer rack is interposed between the timer rack and a timer pin. CONSTITUTION:A fuel injection pump Z sends fuel under pressure by reciprocating a plunger 3.

IPC: H02P29/00
Filed: 1989-03-29
Abstract: PURPOSE:To momentarily obtain phase lock operation when a rotary driving body is activated by controlling a reference signal to be inputted to a phase frequency detector. CONSTITUTION:The reference signal can be obtained through a presettable frequency divider 39. When the preset of the presettable frequency divider 39 is executed by a preset signal generation circuit 39 and the phase deviation of a signal to be compared by a phase frequency detector 37 is in a prescribed range, there is no phase lock signal and the preset is executed at the timing of a prescribed phase between a frequency lock signal P1 from a frequency detector 34 and a rotation detecting signal. Thus, the reference signal is corrected so as to be matched with the phase of the rotation detecting signal by the preset of the presettable frequency divider 39 and a phase lock state can be obtained more early. Thus, when the rotary driving body is activated, the phase lock operation can be momentarily obtained.
