Patent number: 10690183Abstract: In this motion guide device (10), a track member (20) has a recess or protrusion (51) that is formed in a longitudinal direction, and a moving member (30) has a holding protrusion or holding recess (53) that corresponds to the recess or protrusion (51) formed in the track member (20). When force is applied in a direction that would cause relative separation of the moving member (30) and the track member (20), the holding protrusion or holding recess (53) holds onto the recess or protrusion (51) such that the moving member (30) and the track member (20) are unable to be separated. With this configuration, a motion guide device that is both compact and capable of withstanding a strong external load can be obtained.Type: GrantFiled: August 18, 2017Date of Patent: June 23, 2020Assignee: THK CO., LTDInventors: Hiroaki Mochizuki, Eiji Hosaka, Hiroomi Kuribayashi, Toshiro Minami, Akito Kaneko

Publication number: 20110214603Abstract: The present invention provides a method of manufacturing a silicon single crystal which can more greatly suppress a pinhole formation in the silicon single crystal, which is a method of manufacturing a silicon single crystal by the Czochralski method in which a silicon material to be silicon melt is melted in a furnace body and then a silicon single crystal is pulled up. After melting the silicon material and before the start of pulling up the silicon single crystal, a heater power is set to be higher than that during the step of pulling up the silicon single crystal, and an internal furnace pressure is set as 30 Torr or less, which is lower than that during the step of pulling up the silicon single crystal, the power and pressure being maintained for a predetermined time, and then the step of pulling up the silicon single crystal is carried out.Type: ApplicationFiled: February 28, 2011Publication date: September 8, 2011Applicant: COVALENT MATERIALS CORPORATIONInventor: Toshiro MINAMI

Publication number: 20090038537Abstract: A method of pulling up a silicon single crystal is provided in which a variation rate of a neck diameter is controlled to be within a predetermined range, and a dislocation in a neck is eliminated. When pulling up the silicon single crystal, a single crystal with a predetermined crystal diameter is grown by bringing a seed crystal into contact with a material silicon melt, pulling up the seed crystal, growing the neck, and then increasing a diameter. The above-mentioned neck diameter is increased and decreased to grow the neck, during which a neck diameter variation rate is greater than or equal to 0.05 and less than 0.5, assuming that a value obtained in such a manner that a neck diameter difference (A?B) between adjoining inflection points is divided by a neck length L between the above-mentioned inflection points P1 and P2 is the neck diameter variation rate.Type: ApplicationFiled: August 5, 2008Publication date: February 12, 2009Inventor: Toshiro MINAMI

Patent number: 6708199Abstract: A distributed search system that includes a plurality of agents connected on a network that includes an information resource provider. Each of the agents stores information corresponding to information resources in a storage device of a nearest agent as advertisement information. The stored advertisement information includes cost information. An agent which receives the advertisement information transfers the advertisement information to other agents in a range determined on the basis of the cost information. The cost information may be included in a search request of an information resource searcher making a search request to search the stored advertisement information. The information resource searcher sends the search request including the cost information to agents in a range of transmission corresponding to the cost information included in the search request.Type: GrantFiled: December 22, 2000Date of Patent: March 16, 2004Assignee: Fujitsu LimitedInventors: Takeshi Ohtani, Toshiro Minami

Patent number: 6212545Abstract: A distributed search system that includes a plurality of agents connected on a network that includes an information resource provider. The information resource provider registers information corresponding to information resources to his nearest agent. The agent stores that information in its storage device and transfers it to the neighboring agents as advertisement information. The transferred advertisement information includes cost information. The agents which receive the advertisement information store it in their storage devices and transfer the advertisement information to the neighboring agents repeatedly, in a range determined on the basis of the cost information. The cost information may be included in a search request of an information resource searcher making a search request to search the stored advertisement information.Type: GrantFiled: October 28, 1998Date of Patent: April 3, 2001Assignee: Fujitsu LimitedInventors: Takeshi Ohtani, Toshiro Minami
