Title: Screen photoreceptor
Inventor: MURAI KEIICHI
IPC: G03G15/05
Filed: 1980-03-14
Abstract: PURPOSE:To prevent a copied picture from deteriorating in quality owing to the deterioration of the surface of a conductive member as a screen base, by applying silicone oil within a specific range of viscosity to the conductive member side within a specific range of thickness. CONSTITUTION:On the reverse surface (opposing to photoconductive member 2 and insulating member 3) of conductive member 1 which is the base of a screen photoreceptor, silicone oil of 100-105cst, specially 500-10<4>cst in viscosity expressed by formula I [where n is a positive integer, R1 is CH2CH2CF3 or the group  expressed by formula II, and R2, R3 and R4 are CH3 and phenyl providing R1, and  R2 may be equal or different] is applied to a thickness of 0.03-3mum. Consequently,  electric resistance of the reverse surface of conductive member 1 increases according  to the sticking of contaminants and deterioration, electrostatic charges are held on the reverse surface of conductive member, and the efficiency of an ion flow passing through the photoreceptor varies, so that the electrophotographic fogging of an original white part will be prevented. Thus, the life of the photoreceptor is prolonged. In case that silicone oil is contaminated after long-period use, new silicone oil is applied and the old one is wiped off to restore the original performance.

Abstract: PURPOSE:To improve the accuracy of measurement, to expedite a measuring operation, and to enable the attainment of a small-sized and light measuring device, by conducting zero-adjustment of the measuring device just before measurement by a vessel to be employed in an actual measuring operation. CONSTITUTION:An empty test tube 7 is inserted into a vessel insertion part 5, a source switch button 4 is pushed, and adjustment is made by a zero-adjustment knob 3 so that the indicator of a meter 2 for indicating a measured value points to the zero of an MLSS density value 19. Next, the test tube 7 is pulled out from the insertion part 5. Then the test tube 7, in which a liquid taken out from an air-seasoning tank is put, is inserted therein again, and a value of MLSS density is read. On the occasion, a light emitted from a miniature bulb 10 is transmitted through the test tube 7 and the liquid contained therein and received by a cds 11, and a current value of a circuit on the cds 11 side is changed thereby and indicated by an ammeter 15 (the meter 2). Since the concentration value 19 obtained by converting the current value into the MLSS concentration beforehand is indicated in the meter 2, a value indicated by the indicator is read at this time.

Title: Solid-liquid separator
Inventor: HONMA TADAO
IPC: B01D21/26
Filed: 1994-02-07
Abstract: PURPOSE:To separate coarse particles and fine particles simultaneously and separately by installing an inclined plate module in the upper part of a region divided by the inner surface of the 1st inner cylindrical part and the outer surface of the 2nd cylindrical part and installing fine particle sludge collecting plates in the lower part. CONSTITUTION:By a turning flow in a region between the cylindrical wall part of a separating tank 1 and the 1st inner cylindrical part 2, coarse particles in a suspension are sedimented and accumulated to the bottom part of the separating tank 1. On the other hand, the suspension from which the coarse particles have been removed and which contains fine particles is fed to a region between the inner wall of the 1st cylindrical part 2 and the outer wall of the 2nd cylindrical part 3 and is straightened by an inclined plate module 6 to allow the fine particles to be settled by gravity. Since the fine particles thus settled by gravity are collected by fine particle collecting plates 5 installed under the inclined plate module 6, they are not mixed with the coarse particles collected in the bottom part of the separating tank 1. Therefore, the problem caused by the mixing of the fine particles with the coarse particles is solved.
