Patent number: 7231318Abstract: A predicted corrosion amount of a painted or unpainted atmospheric corrosion resistant steel is calculated by using extrinsic corrosion information including weather observation data, an amount of airborne salt, and an amount of sulfur oxide in a planned location for use where the atmospheric corrosion resistant steel is to be used, and intrinsic corrosion information on components of the atmospheric corrosion resistant steel. The weather observation data on this occasion preferably includes the annual wetness time, annual mean wind speed, and annual mean temperature. Moreover, it is preferable to calculate a corrosivity index, estimate a first-year corrosion amount of the atmospheric corrosion resistant steel and a rust stabilization index from the corrosivity index, and calculate a corrosion amount accumulated over time.Type: GrantFiled: July 11, 2002Date of Patent: June 12, 2007Assignee: Nippon Steel CorporationInventors: Hiroshi Kihira, Yasumori Fujii, Yoshiyuki Harada, Takashi Kusunoki, Norihito Fujikawa, Hiroshi Takezawa, Hiromichi Yasunami, Kazumi Matsuoka

Patent number: 5288898Abstract: As new compounds are now provided N-methyl-3-(3,4-dihydroxyphenyl)serine alkyl esters which are effective as an .alpha.-adrenergic and .beta.-adrenergic agent to stimulate the .alpha.-adrenergic and .beta.-adrenergic functions of the central nervous system of mammalian animals and are expectable to be useful for therapeutic treatment of disorders as invoked by reduced biological activities or functions of the .alpha.- and/or .beta.-adrenergic neurons. N-methyl-L-threo-3-(3,4-dihydroxyphenyl)serine (C.sub.1 -C.sub.6) alkyl esters are preferred amongst the new compounds of this invention.Type: GrantFiled: May 4, 1993Date of Patent: February 22, 1994Assignee: Zaidan Hojim Biseibutsu Kagaku Kenkyu KaiInventors: Hamao Umezawa, Toshiharu Nagatsu, Tomio Takeuchi, Hajime Morishima, Yoshio Sawasaki, Hiroshi Takezawa, Fujinori Sasaki

Patent number: 5173997Abstract: A tongue plate stopper has a first disc having its webbing side face formed with at least one needle to be inserted through a webbing; and a second disc having a fitting portion for fitting the needle therein. At least one of the first and second discs has its webbing side face formed with a plurality of pins for biting into the webbing. The needle of the first disc projects from the central portion thereof. The fitting portion of the second disc has a hole. The pins include a first set of pins projecting from the circumferential edge of the back face thereof and at a circumferential spacing from one another, and a second set of pins projecting from the middle portion between the needle and the circumferential edge and at a circumferential spacing from one another.Type: GrantFiled: December 19, 1991Date of Patent: December 29, 1992Assignee: Takata CorporationInventors: Hiroshi Takezawa, Ichiro Nakagawa, Masahiro Tanabe, Masanaga Tsuchikawa
