Patent number: 8720406Abstract: There is provided, in one aspect of the present description, an engine. In one example, the engine comprises a cylinder block, a cylinder head, a sheet metal gasket interposed between the block and the head, a first projection projecting outwardly and laterally from a side portion of the block, and a second projection projecting outwardly and laterally from a side portion of the head, the first projection and the second projection facing each other along a coupling surface between the block and the head. The engine further comprises an extension extending from a main body of the sheet metal gasket and located between the first projection and the second projection, and a resilient portion which is provided in the extension, formed resiliently in a direction perpendicular to the coupling surface, and compressed between the first projection and the second projection when the head is fastened on the block.Type: GrantFiled: November 1, 2010Date of Patent: May 13, 2014Assignee: Mazda Motor CorporationInventors: Naoyuki Abe, Kazuhiro Tomizawa, Yasushi Nakahara, Kiyonori Nagato, Yasuhiro Sudou, Hiroshi Hosokawa, Yuma Miyauchi, Jun Nishikawa, Osamu Torobu, Hiroyuki Abe, Kazuhiro Matsuoka

Patent number: 8512610Abstract: The nonwoven fabric sheet of the present invention is characterized by a porosity in the range of 0.3 to 0.7 and an average pore size in the range of 0.5 ?m to 5.0 ?m. The nonwoven fabric sheet of the present invention preferably has a maximum pore size (?m)/average pore size (?m) ratio of 1.30 or lower. The nonwoven fabric sheet of the present invention is obtained by press-molding a nonwoven fabric at a temperature lower than the melting point of the thermoplastic resin which constitutes the nonwoven fabric sheet. According to the present invention, there is provided a nonwoven fabric sheet that has a high porosity, small uniform pore sizes and excellent productivity, which can suitably be used in various applications such as filters, light diffusing material, liquid absorber and heat insulating materials; and a method for producing the nonwoven fabric sheet.Type: GrantFiled: February 17, 2010Date of Patent: August 20, 2013Assignee: Mitsui Chemicals, Inc.Inventors: Kazuya Okada, Yasuhiro Sudou

Publication number: 20100003588Abstract: Disclosed is a separator for energy devices, which hardly allows an internal short circuit, while excellent in electrolyte solution retention. Also disclosed is an energy device comprising such a separator. Specifically disclosed is a separator for energy devices, which comprises a nonwoven fabric laminate composed of two or more melt-blown nonwoven fabric layers arranged on top of one another. Each of the melt-blown nonwoven fabric layers has an average fiber diameter of 0.5-3 ?m, and the weight per square meter of the nonwoven fabric laminate is not more than 50 g/m2. This separator for energy devices has a surface centerline roughness (Rt value) of not more than 35 ?m.Type: ApplicationFiled: August 10, 2007Publication date: January 7, 2010Applicant: MITSUI CHEMICALS, INC.Inventors: Yasuhiro Sudou, Masataka Iwata
