Filed: 1988-11-30
Abstract: PURPOSE:To manufacture a steel member excellent in fatigue strength by forming the structure of a steel member into a metallic structure composed principally of bainite, subjecting the above steel member to nitriding treatment, and then applying shot peening treatment to the above under specific conditions. CONSTITUTION:A steel member is hot-forged and cooled or is heated up to a temp. of the austenitizing temp. or above and cooled, by which the structure of the above steel member is formed into a metallic structure composed principally of bainite in which area ratio of bainite structure is regulated to >= about 50%. Subsequently, nitriding treatment or soft nitriding treatment is applied to the above steel member, by which a film of iron nitride (Fe2N, Fe3N, Fe4N) is formed to a thickness of about 10 to several tens microns on the surface layer of the steel member and also a diffused nitrogen layer is formed inside. Further, shot peening treatment is applied to the above steel member under the conditions of 15-60 ratio of shot diameter to thickness of nitrogen compound film, 45-60 Rockwell hardness of shot, and 50-120m/sec shot velocity. By this method, the steel member remarkably improved in fatigue strength can be obtained.

Title: Construction of wooden floor
Inventor: HIRAUE KEISHIYOU
IPC: E04F15/04
Filed: 1988-12-01
Abstract: PURPOSE:To avoid the occurrence of floor noise as well as make constructing work easier by a method in which a wooden floor panel formed by laminating uneven shock absorbers with a main part is bonded to the surface of a floor base with the aid of an adhesive having no tackiness of paint film after hardened. CONSTITUTION:Uneven shock absorbers 2 such as expanded materials are laminated on the back of a wooden floor base panel 1 to form a wooden floor panel. The wooden floor panels are bonded to the surface of a floor base 4 by using a vinyl acetate- or acryl-based emulsion adhesive containing no filler. Since the coated film of the adhesive 5 has no tackiness after hardened, the floor panels can be strongly bonded to the floor base at their projected parts 3a to prevent the repeating actions of adhesion and separation at the projected parts 3b in relation to the floor base. The occurrence of frictional noise between the shock absorber 2 and the adhesive layer 5 can thus be avoided.

Abstract: PURPOSE: To stop the polymerization reaction while dispensing with the removal of a catalyst by adding a specified hindered amine compound to a polymer obtained through bulk polymerization of trioxane, etc., in the presence of a boron trifluoride base catalyst. CONSTITUTION: A polymerization reaction is stopped by adding a hindered amine compound of the formula (wherein R<1> to R<4> are each 1-5C alkyl; n is an integer of 1 or greater; and R<5> is an n-valent organic residue) to a polymer obtained through bulk polymerization of trioxane or a mixture of trioxane with a cyclic ether and/or a cyclic acetal in the presence of at least one polymerization catalyst selected from the group consisting of BF3 , BF3 hydrates and coordination compounds of BF3 with O- or S-containing organic compounds. The polymer obtained by adding the hindered amine compound to stop the polymerization reaction dispenses with the removal of the catalyst. Accordingly, the production process can be greatly shortened, while a polymer with very high thermal stability can be obtained.
