Patent number: 4533402Abstract: A hollow stabilizer manufactured from a material obtained by adding a minute amount (0.001-0.01% by weight) of boron to either a carbon steel tubing having a relatively low carbon concentration of 0.20-0.35% for mechanical and structural purposes or to a carbon steel tubing for general structural purposes. The carbon steel tubing thus provided is bent in a prescribed stabilizer form. The bent tubing is water quenched, for example, to a greater hardness than HRC 43. The water-hardened bent tubing is later tempered to a hardness HRC, ranging between 36 and 43, at a temperature of, for example, 300.degree.-380.degree. C. for a proper length of time. The hollow stabilizer obtained by the aforementioned heat-treating steps has a much greater fatigue strength.Type: GrantFiled: February 16, 1984Date of Patent: August 6, 1985Assignee: NHK Spring Co., Ltd.Inventors: Akira Ohno, Hiroshi Koyama, Kanji Inoue, Hiroaki Ozawa

Patent number: 4526628Abstract: A car stabilizer and a manufacturing method therefor are disclosed. In this method, a straight elongated starting material of carbon steel with a carbon content of 0.10% to 0.35% is first directly quenched by quick heating, and then bent into a predetermined shape. Thereafter, the material is annealed at a low temperature of 100.degree. C. to 400.degree. C., shot-peened as required, and then coated. Thus, a stabilizer is obtained as a final product. The coating may be executed between the steps of quenching and bending.Type: GrantFiled: September 20, 1984Date of Patent: July 2, 1985Assignee: NHK Spring Co., Ltd.Inventors: Akira Ohno, Kanji Inoue

Patent number: 4448855Abstract: The present invention is intended for a heat resistant reflector in which a light reflective metal is vacuum coated on a metal or inorganic material substrate and in which on the surface of the vacuum coated layer is further vacuum coated a light transmissible ceramic and preferably, a ceramic having a crystalline substance. This reflector has a light reflective metal and a ceramic vacuum coated together, and thus, can form a thin film of the same replica as a substrate. Therefore, there is very little refraction or absorption of light due to a protective film, cnanges of total reflectivity, regular reflectivity or refractivity are very few and its manufacture as well is simple because of continuous vacuum coating with one and the same coating machine.Type: GrantFiled: November 13, 1979Date of Patent: May 15, 1984Assignees: Kiko Co., Ltd., NHK Spring Co., Ltd.Inventors: Susumu Senaha, Suizo Kyo, Susumu Shimomura, Akira Akagami, Hiroshi Imai, Akira Ohno, Shitomi Katayama, Suguru Nomura
