Patent number: 9415463Abstract: This invention provides a laser marking method that can form a very minute mark of a predetermined shape, such as a letter or pattern, with clarity and high solidity, on the surface of a substrate. The laser marking method of the invention comprises the steps of (1) depositing a coloring material on the surface of a substrate of thermoplastic material to form a thin film of the coloring material, and (2) applying a laser beam to the thin film of the coloring material in conformity with a predetermined marking shape to cause the portions of the substrate irradiated with the laser beam to soften and to cause the thus softened portions to mix with the coloring material, thereby developing the predetermined marking shape on the surface of the substrate.Type: GrantFiled: January 26, 2010Date of Patent: August 16, 2016Assignees: Shizuoka Prefecture, Shikibo Ltd., Nidek Co., Ltd.Inventors: Hiroyasu Ueta, Minoru Inuzuka, Yutaka Tsujimoto

Patent number: 8991641Abstract: A toroidal pressure vessel having extremely high pressure resistance has laminated latitudinal reinforcing fiber layers to improve a strength in a latitudinal direction of the pressure vessel. Moreover, putting reinforcing fibers constituting those laminated latitudinal reinforcing fiber layers in continuity enables further improvement of strength in the latitudinal direction of the pressure vessel, for example compared with a case where the reinforcing fibers are divided for each layer.Type: GrantFiled: April 15, 2011Date of Patent: March 31, 2015Assignees: Mitsubishi Heavy Industries, Ltd., Shikibo Ltd.Inventors: Tetsuya Ozawa, Nozomu Kawasetsu, Kentaro Shindo, Mitsuru Kondo, Akira Fukushima, Masayasu Ishibashi, Takeshi Tanamura, Kazuo Nakajima, Hiroshi Sakai, Tetsuro Hirokawa

Patent number: 7384585Abstract: A novel process for producing a dry preform for a composite material takes advantage of the fact that a reinforcing filament assembly, when consisting of a fiber reinforcement layer a, formed by stringing a first set of parallel strands of fiber reinforcement over a part or all of the plane within any desired shape along the straight axis 2, and a fiber reinforcement layer b, formed by stringing a second set of parallel strands of fiber reinforcement over the plane at an angle ? with respect to the straight axis 2, such that 0°<?<180°, the part of the reinforcing filament assembly that consists solely of the fiber reinforcement b can be deformed as desired. According to this process, strands c of fiber reinforcement are strung using a fiber reinforcement string jig as shown in FIGS. 8(A) and 8(B). The layers of the strung strands of fiber reinforcement are brought together by a simple means such as stitching.Type: GrantFiled: May 28, 2003Date of Patent: June 10, 2008Assignee: Shikibo Ltd.Inventors: Masayasu Ishibashi, Koichi Hashimoto, Hideki Sakonjo, Akira Iriguchi, Kazunori Morimoto, Takeshi Tanamura, Tetsuro Hirokawa

Patent number: 7138167Abstract: A preform for a fiber-reinforced composite material including a bent portion along a curved line for bending, a flange portion corresponding to an outer circumferential portion, and a semi-cylindrical portion formed by bending an inner circumferential portion along the curved line for bending located in a flat plane or a curved plane region. The preform is formed from a precursor having a predetermined extension. The outer circumferential portion corresponds to a first region where a first plurality of reinforced fibers is partially disposed in parallel along the curved line for bending. The inner circumferential portion corresponds to a second region constituted solely of a second plurality of reinforced fibers disposed throughout the entire area, so as to intersect the first plurality of reinforced fibers at a predetermined angle in the first region.Type: GrantFiled: August 12, 2002Date of Patent: November 21, 2006Assignee: Shikibo Ltd.Inventors: Hideki Sakonjo, Masayasu Ishibashi, Takeshi Tanamura, Koichi Hashimoto, Tetsuro Hirokawa

Patent number: 7114319Abstract: A unidirectional three dimensional fiber structure is provided which does not require weaving, displays a high level of interlayer strength and does not suffer from cracking, and which can also be easily produced with any arbitrary cross-section. A unidirectional three dimensional fiber structure is produced by inserting a plurality of long fibers which have been aligned unidirectionally into an inlet at one end of a cylindrical die with a plurality of needle holes in the peripheral walls thereof, and then performing needlepunch through the needle holes while drawing the plurality of long fibers out from an outlet at the opposite end of the cylindrical die.Type: GrantFiled: April 4, 2003Date of Patent: October 3, 2006Assignee: Shikibo Ltd.Inventors: Hideki Sakonjo, Masayasu Ishibashi, Tetsuro Hirokawa, Takeshi Tanamura, Koichi Hashimoto
