Title: Dispersion, electrophotographic photoreceptor, electrophotographic process, electrophotographic apparatus, and process cartridge for electrophotographic apparatus
Inventor: NIIMI TATSUYA
IPC: C09B67/46
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To obtain a dispersion desirable for making stable electrophotographic photoreceptors by adding a polyvinyl acetal to a dispersion containing titanyl phthalocyanine which has a specified maximum diffraction peak to the characteristic X rays of CuKα. SOLUTION: A polyvinyl acetal having a degree of acetylation of 4 mol.% or above is added to a dispersion containing titanyl phthalocyanine which has a maximum diffraction peak at a Brag angle 2θ of 27.2±0.2 deg. to the characteristic X-rays (at a wavelength of 1.541 Å) of CuKα to make a dispersion for making a photographic photoreceptor. The polyvinyl acetal used is represented by formula I (wherein R is a 1-5C alkyl; and l, m and n are each the number of the units in the parentheses). The titanyl phthalocyanine has a basic structure represented by formula II (wherein X1 to X4 are various halogens; and p, q, r and k are each a number of 0-4). The combination of this titanyl phthalocyanine with the dispersion containing the polyvinyl acetal as a specified binder gives a photoreceptor which exhibits excellent electrostatic characteristics in repeated use.

IPC: G06T1/20
Filed: 1990-09-14
Abstract: PURPOSE:To accurately detect a mark position without being affected by the condition of the surface of an alignment mark prepared on a substrate by detecting the minimum one of configurations similar to a predetermined configuration at least partly in contact with the positioning mark obtained from a binary image signal and by using the position of the detected minimum configuration to detect the position of the positioning mark. CONSTITUTION:A pattern is detected (reference number 40), encoded into a binary value (reference number 41), and converted into a two dimensional binary digital image, followed by detecting the outermost border line of the pattern (reference number 42), further followed by obtaining summits of a totally convex polygon from a group of points composing the outermost border line (reference number 43), furthermore followed by obtaining the farmost point Voronoi-diagram for the summits of the totally convex polygon (reference number 44), again followed by obtaining a circle with the minimum radius from circles having the center at the Voronoi point and passing the three points corresponding to three Voronoi areas adjacent to the Voronoi points, that is, the minimum inclusive circle (reference number 45), and finally followed by letting the center of this minimum inclusive circle be the position of positioning mark. The minimum inclusive circle can be determined at a constant position despite a defect of the profile section, thereby being able to detect the position of the substrate accurately. With this, the position of a substrate can be accurately detected. Since the inclusive configurations have only to be circum-scribed about the positioning mark, they have only to be made similar to one another.

Title: Method for stopping operation of phosphoric fuel cell
Inventor: KAMOSHITA TOMOYOSHI
IPC: H01M8/04
Filed: 1989-09-20
Abstract: PURPOSE:To safely stop a fuel cell without using inactive gas and make unnecessary the use of a heat reserving heater of the cell during stopping by reducing the density of a phosphoric acid i.e., an electrolyte by means of generating water generated when cell operation is stopped, and substituting combustible gas in a fuel electrode by inactive gas. CONSTITUTION:Hydrogen contained in fuel gas to be fed to a fuel gas circulation line 2 including a fuel electrode 11, and oxygen in reaction air directly react with each other because of the electrode catalyst action of the fuel electrode 11, thereby generating water, and the generated water is adsorbed to a highly absorptive phosphoric acid so that the density of a phosphoric acid solution is reduced to a predetermined density range. Thus the fuel cell is prevented from being damaged by crystallization of the phosphoric acid when atmospheric temperature is lowered. After a predetermined time elapses, feed and discharge of the fuel gas is stopped and gas contained in the fuel electrode 11 is circulated so that air for consuming hydrogen is supplied from an air inlet opening 24. Thus combustible gas components contained in the fuel gas circulation line 2 including the fuel electrode 11 are decreased and the hydrogen density is readily reduced and gas substitution is enabled without requiring a nitrogen cylinder, etc., for gas substitution.
