Title: Method for selection of resist material
Inventor: YOSHIKAWA KOTA
IPC: H01L21/027
Filed: 1985-07-22
Abstract: PURPOSE:To enable the generation of pinholes in a resist film to be prevented by a method wherein the solution of a resist material is analyzed using a gas chromatography, and the impurities which cause generation of pinholes on the resist film are detected. CONSTITUTION:The solution and the solvent of resist material having different frequency of generation of pinholes are analyzed using a gas chromatography, and the impurities (hexahydronaphthalene derivative, for example) corresponding to the generation of pinholes are specified.

Title: High magnetic permeability ferrite material and its production
Inventor: KOZUKA YOSHINARI
IPC: C30B29/22
Filed: 1987-06-27
Abstract: PURPOSE:To advantageously produce the title ferrite material having high magnetic permeability in a high-frequency region by bringing ferrite compacts having different calcining shrinkage rates into contact with each other to obtain a composite, and calcining the composite to form at least one of the compacts into a single crystal. CONSTITUTION:Two or more kinds of the ferrite compacts having different calcining shrinkage rates are brought into contact with each other to form a composite. The composite is calcined, and at least one compact constituting the composite is formed into a single crystal during or after calcining. The particle size of the ferrite powder constituting each compact is changed, or the raw material to be used for the production of ferrite powder is changed in the ferrite compacts in contact with each other to change the calcining shrinkage rate. As the difference between the calcining shrinkage rates is increased, more internal strains are imparted to the finally obtained single crystal ferrite. When the difference is excessively increased, cracks are generated, and the permeability is lowered. Consequently, the difference between the calcining rates is generally controlled to <5%.

Abstract: PURPOSE:To simplify signal processing in the device in the title, in which a body to be detected is buried in a belt, by finding out sensor passing time of each body to be detected, based on the belt traveling distance, and outputting a longitudinal-cleavage occurring signal if a normal signal from each body to be detected is not inputted when the specified body to be detected passes the specified sensor. CONSTITUTION:When bodies to be detected C1 to Ck, which are buried in a conveyor belt 11, pass a sensor 1, whether the body is normal or disconnected is detected, and the result is inputted into a control means 3. On the other hand, a pulse generating means 2 sends a pulse corresponding to a travel distance of the belt 11 to the control means 3. The control means 3 computes the distance among the bodies C1 to Ck, based on the input pulse count, in order to find out the time at which the bodies to be detected C1 to Ck passed the sensor 1. Thus, by receiving the signal, which indicates the time when the bodies to be detected C1 to Ck passed the sensor 1, whether the specified body is normal or not can be judged.
