Patent number: 11931974Abstract: A filament winding apparatus includes a rail extending in a first direction, a core material support device that supports a core material, and a winding device that winds a fiber bundle onto an outer peripheral surface of the core material, the winding device including: a guide unit having an opening through which the core material passes, and guiding the fiber bundle; and a main frame on which the guide unit is mounted; wherein the main frame is movable relative to the core material in the first direction, the main frame is movable in a second direction orthogonal to the first direction, and the main frame is rotatable around a first rotational axis extending in a third direction orthogonal to each of the first direction and the second direction.Type: GrantFiled: November 12, 2019Date of Patent: March 19, 2024Assignee: Murata Machinery, Ltd.Inventors: Shu Ikezaki, Motohiro Tanigawa, Tadashi Uozumi, Hirotaka Wada, Masatsugu Goyude, Shota Miyaji, Takahiro Miura, Makoto Tanaka, Daigoro Nakamura, Tetsuya Matsuura

Patent number: 11931949Abstract: A filament winding device includes a fiber bundle retainer that temporarily retains fiber bundles. The fiber bundle retainer includes: a reel member including an outer peripheral portion having pins movable in the axial direction relative to the fiber bundles supplied through fiber bundle guides and rotatable about the axis of the liner, the reel member capable of winding the fiber bundles onto the outer peripheral portion; a first cutting unit configured to cut a part of each of the fiber bundles in the circumferential direction, the part being between a part of the fiber bundle wound on the outer peripheral portion and a part of the fiber bundle wound on the liner; and a second cutting unit different from the first cutting unit and configured to cut a part of each of the fiber bundles in the axial direction, the part being wound on the outer peripheral portion.Type: GrantFiled: December 17, 2019Date of Patent: March 19, 2024Assignee: Murata Machinery, Ltd.Inventors: Shu Ikezaki, Motohiro Tanigawa, Tadashi Uozumi, Hirotaka Wada, Takahiro Miura, Makoto Tanaka, Masatsugu Goyude, Shota Miyaji, Daigoro Nakamura, Tetsuya Matsuura

Patent number: 8396837Abstract: When accepting a write request including a data, an apparatus 100A acquires a first hash value based on a first hash function and, meanwhile, acquires a second hash value based on a second hash function. When a storage device 110A has not stored the acquired first hash value and second hash value in correlation with each other, the apparatus correlates the data, the first hash value, the second hash value, and information of referenced times, and then stores the correlated items into the storage device. On the other hand, when the storage device has stored the acquired first hash value and second hash value in correlation with each other, the apparatus changes the information of referenced times stored in correlation with the first hash value and the second hash value so as to add one to the number of times denoted by the information of referenced times.Type: GrantFiled: October 14, 2009Date of Patent: March 12, 2013Assignee: NEC CorporationInventor: Masatsugu Matsuura

Patent number: 7693166Abstract: A TOE (TCP/IP Offload Engine) can transmit data to and receive data from a network without causing a plurality of high order processes to influence each other in a computer mounted by a plurality of processors, each of which is mounted by a plurality of cores. The TOE 101 generates a notification queue for each high order process. The TOE driver 102 holds information that tells which high order process corresponds to which socket and which notification queue. When transmitting data, the outgoing data are temporarily held on the transmission buffer queue 102-4 and the transmission buffer is added to the notification queue that corresponds to the relevant high order process after the transmission. When receiving data, the incoming data are stored in the reception buffer on the reception buffer queue 102-3 and the reception buffer is added to the notification queue that corresponds to the relevant high order process.Type: GrantFiled: February 16, 2006Date of Patent: April 6, 2010Assignee: NEC CorporationInventor: Masatsugu Matsuura

Patent number: 7131602Abstract: The present invention provides an aerosol product, which sprays a large number of independent bubbles in the form of soap bubbles. More specifically, the aerosol product, which sprays a large number of independent bubbles in the form of soap bubbles, is provided by charging an aerosol container with an aerosol composition obtained by emulsifying an aqueous concentrate and a liquefied gas.Type: GrantFiled: April 12, 2002Date of Patent: November 7, 2006Assignee: Daizo CorporationInventors: Takashi Otomo, Masatsugu Matsuura
