Patent number: 9192212Abstract: A laminate for laser bonding of the present invention contains a bonding sheet that is melted by irradiation of laser light and a first member laminated on one surface of the bonding sheet and formed of a thermoplastic foam. The difference between the melting point of the first member (Mfoam) and the melting point of the bonding sheet (Msheet) (Mfoam?Msheet) is ?50° C. to 20° C. and the difference between the melt viscosity of the first member (Vfoam) and the melt viscosity of the bonding sheet (Vsheet) (Vfoam?Vsheet) is 3.0×105 Pa·s to 8.0×105 Pa·s. Preferably, the laminate for laser bonding contains a second member having transparency to laser light laminated on the other surface of the bonding sheet.Type: GrantFiled: October 15, 2009Date of Patent: November 24, 2015Assignee: ASICS CORPORATIONInventors: Junichiro Tateishi, Katsuhiro Imazato, Sadaki Mori, Kenichi Harano, Hironori Kitayama

Patent number: 8461222Abstract: There is provided a shoe sole component that has properties such as strength and cushioning property that are suppressed from being changed even under a wide temperature range from severe cold at ?10° C. or lower to high temperature conditions exceeding 30° C. A shoe sole component includes a cross-linked foam of a resin composition, the resin composition containing a thermoplastic polyolefin resin, in which tan ? (?20° C. to 40° C.) at a frequency of 10 Hz measured according to JIS K 7244-4 is 0.01 to 0.5, and tan ? (?20° C.)/tan ? (40° C.) at a frequency of 10 Hz is 0.7 to 1.3.Type: GrantFiled: July 19, 2011Date of Patent: June 11, 2013Assignee: ASICS CorporationInventors: Sadaki Mori, Katsuhiro Imazato, Kenichi Harano, Akiyuki Morikawa

Publication number: 20100154253Abstract: The present invention provides an outer sole light in weight and excellent in abrasion resistance. The outer sole of the present invention is formed out of a polymer composition with a specific gravity of 0.95 or less, which contains an olefin resin and a styrene elastomer, wherein a storage elastic modulus [E?] and a loss coefficient [tan ?] in a dynamic viscoelasticity measurement (20±3° C., 10 Hz) are 100 MPa to 500 MPa and 0.2 or less respectively, and a maximum tensile stress is 30 MPa or more. The olefin resin contains an ethylene polymer and a propylene polymer, for example. The styrene elastomer contains an ?-methyl styrene.butadiene copolymer, for example. A flaw is hardly occurred on the outer sole in use, so that the outer sole is excellent in abrasion resistance.Type: ApplicationFiled: May 25, 2007Publication date: June 24, 2010Applicant: ASICS CORPORATIONInventors: Katsuhiro Imazato, Sadaki Mori
