Title: Liquid crystal shutter head
Inventor: MASUBUCHI SADAO
IPC: H04N1/23
Filed: 1988-05-20
Abstract: PURPOSE:To obtain a highly-reliable liquid crystal shutter head which comprises few numbers of components, whose volume is small and which is free from a possibility of thermal runaway of a heater, by using a neon lamp as a light source for the liquid crystal head of an electrophotographic liquid crystal printer. CONSTITUTION:A light emitted from a neon lamp 1 as a light source enters a liquid crystal shutter 2. The neon lamp 1 is formed by enclosing a xenon gas and a neon gas, a main component, in a glass tube and by providing filaments in the opposite ends of the glass tube. In order to increase the intensity of the light emitted from the neon lamp 1, an aluminum film is formed in a part other than the part of a slit provided in the surface of the neon lamp 1 facing the liquid crystal shutter 2, on the outer surface of the glass tube of the neon lamp 1. The liquid crystal shutter 2 has a large number of liquid crystal pixels controlling light transmittance. The liquid crystal shutter 2 is kept at a prescribed temperature of 45 degrees C by using a heater 3, so as to secure the high-speed responsiveness of a liquid crystal. The shape of the pixels of the liquid crystal shutter 2 is imaged on the surface of a photo-sensitive drum 6 bycusing a SELFOC lens array denoted by 5, and thereby an electrostatic latent image is formed.

Abstract: PURPOSE:To enable forming a LOCOS without decreasing the area of a cell by bird's beak, by forming the LOCOS by thermal oxidation with silicide produced by implanting carbon, nitrogen, or a carbon or nitrogen compound into a silicon substrate used as a mask. CONSTITUTION:In forming an element isolation area, ions of the same conductivity type as that of a silicon substrate 1 are implanted in the principal surface of the first conductivity type silicon substrate 1 for prevention of inversion. The element isolation area is covered with a mask 4 and ions of an element capable of creating silicide harder to oxidize than the silicon substrate 1, such as nitrogen, carbon, or a nitrogen or carbon compound, are implanted.

Title: Manufacture of electrode active material
Inventor: MITACHI TAKEHITO
IPC: H01M4/48
Filed: 1987-05-21
Abstract: PURPOSE:To form an electrode active material of excellent charge discharge characteristics in a simple method and at a low cost by heat processing at a specified temperature a deposit or residual solid material obtained from hydrolysis solution of oxyvanadium chloride. CONSTITUTION:Oxybanadium chloride is hydrolyzed in an aqueous solution. Hydrolysis solution thus obtained is concentrated or alkali is added to, or alkali is added to and concentrated; then a solid substance is deposited or remains. The deposited or the residual solid substance is heat-treated at a temperature of 150 to 350 deg.C. If the temperature of heat treatment is lower than 150 deg.C, the condensation of vanadic acid is not enough and also the removal of physically absorbed water is not enough thereby the temperature is improper. If the temperature exceeds 350 deg.C crystal water is removed and the substance is transformed to vanadium pentoxide thereby the temperature is also improper. By the use of this method the production process becomes very simple, so that mass production and cost reduction become possible and moreover an active material of excellent charge discharge characteristics can be obtained.
