  • Vibration isolating supporter
    Patent number: 5624104
    Abstract: It is an object to effectively and rapidly damp vibration of a vibrating object. A vibration isolating supporter includes a coil spring (3) interposed between an upper frame (1) and a lower frame (2) which are opposed to one another in a vertical direction, and is characterized in that a partition panel (4) is provided for the lower frame (2) to surround a periphery of the coil spring (3), a damping material (5) is accommodated in a portion surrounded by the partition panel (4), and a resisting member is disposed to be suspended in a hollow hole of the coil spring (3) of the upper frame (1) so as to be immersed in the damping material (5).
    Type: Grant
    Filed: January 16, 1996
    Date of Patent: April 29, 1997
    Assignees: Nippon Steel Corporation, Showa Electric Wire and Cable Co., Ltd.
    Inventors: Koumei Hukuda, Kenji Takuma, Minori Kuriyama, Yoshimitsu Murahashi, Hiroaki Kawakami, Yuji Iida, Kazuki Inaba, Hiroyuki Tanaka, Katsumi Shimizu

  • Process for producing low viscosity lubricating base oil having high viscosity index
    Patent number: 5462650
    Abstract: A process for the production of a high viscosity index, low viscosity lubricating base oil having a kinematic viscosity of 3.0 to 5.0 mm.sup.2 /s at 100.degree. C., a viscosity index of 120 or more and a pour point of -10.degree. C. or less, while simultaneously producing a high quality fuel oil, which includes using at least one of a heavy gas oil fraction and a light vacuum gas oil fraction as a stock oil that contains about 60% by volmme or more of distillate components within a distillation temperature range of from about 370 to about 480.degree. C. and about 50% by mass or more of saturated hydrocarbons, subjecting the stock oil to hydrocracking in the presence of an amorphous silica alumina catalyst, separating the cracked product into a fuel oil fraction and a lubricating oil fraction by atmospheric distillation, and subsequently subjecting the lubricating oil fraction to dewaxing, optionally applying at least one of solvent refining and hydrofinishing.
