Patent number: 6913105Abstract: A shock-absorbing mechanism for a power-transmission device includes a cylindrical driven-side shaft coupled to the driving-side shaft through a constant-velocity joint to be axially relatively slidable with respect to the driving-side shaft, a center bearing for rotatably supporting the driving-side shaft to the vehicle body, and a labyrinth mechanism for sealing the inside of the center bearing. An end of the driven-side shaft on the side of the driving-side shaft is disposed axially opposite to the labyrinth mechanism. When the two shafts are slid in the direction to approach each other by an axial load input thereto, the end of the driven-side shaft collides axially with the labyrinth mechanism.Type: GrantFiled: April 1, 2003Date of Patent: July 5, 2005Assignee: Hitachi, Ltd.Inventors: Toshiyuki Masuda, Masao Sakamoto, Shinichi Kondo, Masao Kishi

Publication number: 20040195543Abstract: The object of the invention is to provide polyester-based fiber which maintains physical properties of usual polyester fiber, such as heat resistance, strength and elongation and is excellent in setting ability with controlled gloss of the fiber, artificial hair using the same, a method of producing polyester-based fiber, and a method of producing artificial hair by using the same. To achieve the object, a composition obtained by melt-kneading polyalkylene terephthalate or a copolymerized polyester (A) based on polyalkylene terephthalate, polyarylate (B) and a phosphite compound (C) is melt-spun to form fiber. In the case of melt-kneading, the ester exchange reaction of components (A) and (B) is prevented due to the inhibitory effect of the component (C) on the ester exchange reaction, the heat resistance and physical properties of the fiber are not deteriorated, and a matte effect is brought about by formation of protrusions on the surface of the fiber.Type: ApplicationFiled: January 5, 2004Publication date: October 7, 2004Inventors: Toshiyuki Masuda, Toyohiko Shiga, Toshihiro Kowaki

Patent number: 6280340Abstract: An impact-absorbable power transmission device is constituted by establishing a frictional spline connection between a shaft and a pipe to allow an axial slide therebetween and to forbid a relative rotation therebetween. An inner race of a universal joint is fixed to another end portion of the shaft by press-fitting. A flange for receiving a press-fitting force of the inner race is formed at an intermediate portion of the shaft. Therefore, the power transmission device ensures an impact absorbing performance while avoiding a lowering of a mechanical strength caused by the inner race installing operation.Type: GrantFiled: March 11, 1999Date of Patent: August 28, 2001Assignee: Unisia Jecs CorporationInventor: Toshiyuki Masuda
