Publication number: 20110192528Abstract: There is provided a process for producing a tube member made of fiber-reinforced resin in which it is unnecessary to fold back an end portion of a fiber layer impregnated with uncured resin, and which is capable of joining a tube member, which comprises a resin fiber, and a flanged tube material, which is to be directly rigidly coupled with an engine box or the like, while maintaining the fiber orientation in the initial orientation posture and through an extremely simple process as well. In the process, there is provided a base member 10 comprising a mandrel 1, and an end portion attachment member 2 that is attached to one end thereof and that has a protrusion and a wide diameter portion of a wider diameter as compared to the mandrel. A fiber impregnated with uncured resin is hoop wound around the outer circumference of the mandrel 1 to form a first wound layer 3. A fiber is further helically wound around the outer circumference thereof to form a second wound layer 4.Type: ApplicationFiled: August 8, 2008Publication date: August 11, 2011Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Takahiro Kozaki, Yasunori Nonogaki, Tasuku Takashima

Publication number: 20010036156Abstract: An ATM switching system includes PVC allocation circuits 13-i corresponding to output queues 14-i is disclosed. At the time of arrival of the leading cell of each burst data, if the output line has a room, the PVC of the burst data is stored as information for admission and identification. The subsequently-arriving cells having the same PVC identification information as the stored identification information are “input to an output buffer, and the cells of the remaining burst data are all discarded. Even when a plurality of burst data compete for the same output line, the fact that all the cells other than the first-arriving admitted burst data are discarded prevents the cells from being input other than within a predetermined bandwidth and localizes the burst data affected by the cell discarding due to output queue overflow.Type: ApplicationFiled: June 19, 2001Publication date: November 1, 2001Inventors: Takahiro Kozaki, Morihito Miyagi, Manabu Okamoto
