Title: Propylene block copolymer composition and its production
Inventor: ASANUMA TADASHI
IPC: C08F297/08
Filed: 1981-09-04
Abstract: PURPOSE:To obtain a propylene block copolymer excellent in low-temperature impact resistance and rigidity, by copolymerizing, at a specified reactant ratio, ethylene with propylene which has been polymerized in the presence of a specified catalyst by using propylene itself as a solvent. CONSTITUTION:A solid catalytic component is prepared by contacting anhydrous magnesium cloride with at least one compound selected from the group consisting of carboxylate esters, ethers, orthocarboxylate esters and alkoxysilicons and then contacting the product with a titanium halide. In the presence of a catalyst consisting of the produced solid catalytic component and an organoaluminum compond, propylene alone or a small amount of ethylene and propylene are polymerized at 50-80 deg.C by a bulk polymerization process wherein propylene itself is used as a solvent. Then ethylene and propylene are polymerized at 30- 60 deg.C under a condition in which the reactant ratio is 20/80-90/10 (weight ratio). Then the polymer is separated from the unreacted monomer by evaporation or filtration or the polymer is washed counter-currently with a propylene-based medium and then separated from the medium.

IPC: H01L21/306
Filed: 1978-11-13
Abstract: PURPOSE: To reduce handling damage by performing etching only to the lapped surface of semiconductor wafer, of which one main surface is given mirror finish while another main surface is given lapping, further by removing a generated crushed layer.  
     CONSTITUTION: One main surface of a single crystal silicon wafer 1a is given mirror finish and another main surface is given lapping.

IPC: B24C11/00
Filed: 1991-05-16
Abstract: PURPOSE:To provide shots for shot peening with excellent durability and capable of decreasing deformation, abrasion and crushing in the hard shot peening process by setting the surface hardness of a steel shot with the inner hardness Hv 400-600 to Hv 750 or above. CONSTITUTION:The surface hardness of a shot is set to Hv 750 or above so that the shot is not deformed or abraded when it collides with a work at a high speed, and the inner hardness is set to Hv 400-600 to prevent crushing. Considering the stress distribution generated in the shot when it collides with the work, the position where the maximum shearing stress is generated exists on the surface layer of the shot, thus only the surface layer is required to be made hard to prevent the deformation by the stress, and it is hardly crushed when the inside is made soft. The shot made hard on the surface layer as much as possible and made soft inside is resistant to deformation, abrasion and crushing.
