Title: Silicon semiconductor device
Inventor: SUGASHIRO SHIYOUJIROU
IPC: H01L29/872
Filed: 1983-06-09
Abstract: PURPOSE:To enable the attainment of excellent heat resistance and reliability, by forming a high-melting silicide layer between a transition metal silicide layer and a wiring layer on an Si substrate. CONSTITUTION:A high-melting metal silicide layer 8 composed of WSi2, MoSi2 or the like is formed between a transition metal silicide layer 6 and a wiring layer 5 on an Si semiconductor substrate 1 so as to suppress the interdiffusion of Si and Al between the layers 6 and 5. Since WSi2 or the like is thermally stable in this case, no Si is extricated from the layer 8 and no reaction occurs between the substrate 1 and the layers 6 and 8 and between these layers in heat treatment. Moreover, no reaction occurs between the layers 8 and 5 at a temperature hot higher than 500 deg.C, and in most of methods of manufacturing Si semiconductor devices, heat treatment at a temperature of 500 deg.C or above is not applied practically after wirings are formed. Furthermore, since the melting point of the layer 8 is at 1,300 deg.C or above and the diffusion constant of atoms in the layer 8 is small, the mutual-diffusion of Si in the layer 8 and Al in the layer 5 does not occur.

Title: Method for evaluating adhesion of resin coating applied to film
Inventor: FUJIMATSU SHINYA
IPC: G01J1/00
Filed: 1993-04-28
Abstract: PURPOSE:To non-destructively measure adhesion between a base material film and a resin coating by applying laser light perpendicularly to a film cross section and measuring an amount of light emitted from an opposite cross section. CONSTITUTION:Laser light emitted from a laser light emission source 1 enters inside a film 2 applied with resin 3 from a cross section of the film, passes through the film and reaches an opposite cross section. The laser light reaching the cross section goes out of the film cross section, and this light is received by a photo diode 4. By utilizing a fact that an amount of light leaking to a resin layer is different depending on a degree of adhesion of the resin 3 applied to the film while the light entering the film at this time passes through the film, the amount of light emitted from the opposite cross section is measured, thereby evaluating the adhesion.

IPC: C08F4/60
Filed: 1990-04-19
Abstract: PURPOSE:To obtain the title component which can give polyethylene having a low fine powder content and an excellent particle size distribution in high yield by bringing a specified suspension into contact with TiCl4 and an aliphatic ketone at low temperature, heating the obtained mixture, and further treating with the obtained composition with TiCl4. CONSTITUTION:A suspension obtained by bringing diethoxymagnesium into contact with dichloroethane is brought into contact with TiCl4 and an aliphatic ketone (e.g. 2,6-dimethyl-4-heptanone) at 0 deg.C or below, and the temperature of the mixture is raised over a period of at least 3hr. The mixture is treated at 70-130 deg.C, and the obtained composition is further treated with TiCl4 to obtain a solid catalyst component for the production of polyethylene. When polyethylene is produced by using this solid catalyst component, the influence of chlorine on the formed polymer can be decreased to such an extent that no deashing process is necessary, and the persistence of the activity during polymerization is excellent so that the component is not aged during a long-time polymerization reaction. Especially, polyethylene having a low fine powder content and an excellent particle size distribution can be obtained in high yield.

Abstract: PROBLEM TO BE SOLVED: To improve the durability of a bead part for a separation failure by setting an angle made by an end surface of a steel cord and a radial directional cross section of a tire, in a certain range, and arranging cross section of each steel cord in parallel with each other. SOLUTION: An angle θ, which is made by an end surface (a-b) of a carcass ply reinforcing steel cord 1 and a radial directional cross section R of a tire, is set at 30-65.0 deg., and the end surface (a-b) is arranged in parallel with an end surface (c-d) of an adjacent steel cord so as to widen the space between (b-c) to a range at 1.10 L-1.50L. In the case where the angle θ exceeds 65 deg., a distance (b-c) between the cords becomes practically equal to a distance (f-g) between the cords at the time of the conventional angle at 90 degree, and on the other hand, in the case where the angle θ is less than 30 deg., since the plating is not performed, a cross sectional area of a cord, in which adhesion with rubber is not generated, becomes too wide, and an effect for restricting the spread of crack is not obtained.
