Title: Dehydrogenation and isomerization catalysts for alkyltetralins and usage thereof
Inventor: MAEDA KAZUHIKO
IPC: C07C5/27
Filed: 1987-04-24
Abstract: PURPOSE:To increase the selection efficiency of required isomers by treating Y-type zeolite which is allowed to support one or more of transition metals having atomic numbers 20-30, with alkali to prepare dehydrogenation and isomerization catalysts for alkyltetralins. CONSTITUTION:Y-type zeolite is allowed to support one or more of transition metals having atomic numbers 22-30, and this Y-type zeolite is treated with alkali to obtain dehydrogenation and isomerization catalysts for alkyltetralins. In addition, after the above-mentioned alkali treatment,the zeolite can be further permitted to support one or more of metals such as platinum, palladium, ruthenium and rhodium. In the presence of thee catalysts, alkyltetralins are dehydrogenated and isomerized. This hydrogenation/isomerization reaction allows the alkyl group on the naphthene ring of alkyltetralins to transform at the same time as dehydrogenation. Consequently, the side reaction is restricted and the isomerization is promoted at a high selection rate.

Title: Preventing method of clad material from propagation of bond exfoliation cracking
Inventor: DEWA AKIO
IPC: B01J3/04
Filed: 1984-05-24
Abstract: PURPOSE:To prevent propagation of bond exfoliation cracking when the cracking generates in a clad part of a pressure vessel used at high temp. and under high pressure by providing a vent hole to a base material side of the clad material which has caused the bond exfoliation cracking. CONSTITUTION:An exfoliation crack 3 generates along a bond part of a clad steel and propagates. Accordingly, it is in parallel to the main strain L of the structure in the initial stage, there is no adverse influence insofar as the crack does not grow too large or in the direction of the thickness of the plate. Therefore, the propagation of the crack can be interrupted by preventing trapping of hydrogen by venting hydrogen intruded from the laminated material side 2 by providing a hole 4 from the base material 1 side corresponding to the cracked position at the time when the generation of crack is found. Since the vent hole 4 is sufficiently effective even if the dia. is so small as ca. 5mm.phi, there is no influence on the strength of the base material 1.

Title: Photoelectromagnetic recording medium
Inventor: TANAKA MOTOHARU
IPC: G11B11/105
Filed: 1982-06-18
Abstract: PURPOSE:To eliminate the necessity of considering the influence of a magnetic film to the surface of a substrate and mass-produce the substrate, by installing a vertically magnetized film having a vertical magnetic anisotropy to the flat surface of the substrate having a groove at one side and the flat surface at another side. CONSTITUTION:A vertically magnetized film 2 is installed on the flat surface of a substrate 1 having groove at one side and a protective film 3 is formed on the film 2. When a light beam 5, such as laser beam, etc., is irradiated form the top, the light is irradiated upon the magnetized film 2 because the substrate 1 is transmissive for the light, and the light is reflected at the surface of the film 1 since the film 2 has a mirror surface. Then, the light is reflected from the surface of the substrate 1 with different quantities of light since the convex and concave parts of the substrate 1 have different thicknesses. Therefore, tracking utilizing the difference in reflectivity due to the difference in thickness can be performed. Moreover, the recording can be performed in such a way that the magnetized film 2 is heated to the curie point by irradiating a modulated laser beam upon the convex part of the substrate 1 and inversion in magnetization is performed by applying an external magnetic field under a condition where the coercive force becomes smaller.
