Publication number: 20150299920Abstract: A nonwoven fabric web (3) is mounted on a three-dimensional molding surface (10) of a molding mold (1), and water is sprayed onto this nonwoven fabric web (3) by a water jet (2). Thus, the nonwoven fabric web (3) is pressed against the molding surface (10), and fibers (32) of the nonwoven fabric web (3) are entangled with each other while the nonwoven fabric web (3) is molded so as to conform to the three-dimensional shape of the molding surface (10), whereby a nonwoven fabric molded product (5) of a three-dimensional shape is produced.Type: ApplicationFiled: July 17, 2013Publication date: October 22, 2015Applicant: TAIYO MACHINERY MANUFACTURING CO., LTD.Inventors: Toshiyuki YANAMOTO, Yoshihiro YANAMOTO

Patent number: 8118003Abstract: A pivot cam mechanism included in a valve operating system is configured such that a coupling pin is supported at a pivot member in a position closer to a camshaft than a control shaft, and the pivot member and the driven member are integrally pivotable according to the rotation of the drive cam while changing relative attitudes of the driven member and the pivot member. Positions and shapes of the drive cam, the driven member, and the pivot member are designed so that a valve maximum acceleration point at which an acceleration of a valve body is at a maximum is located in a front part of a valve acceleration period in which the acceleration of the valve body has a positive value while the drive cam is rotating once.Type: GrantFiled: March 11, 2009Date of Patent: February 21, 2012Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Toru Nishida, Kazuki Nagasawa, Yoshio Watanabe, Yoji Fukami, Toshiyuki Yanamoto

Patent number: 7891328Abstract: A lubricating system for a valve operating system includes a valve operating system configured to reciprocate a valve for substantially opening and closing a port connected to a combustion chamber of an engine, and an ejecting device provided with an outlet from which a lubricating liquid is ejected. The valve operating system includes a drive cam, a driven member configured to contact the drive cam, a pivot member which is attached to the driven member and is configured to transmit movement of the driven member to the valve, and a relative position changing device configured to change relative positions of the driven member and the pivot member. The outlet of the ejecting device is oriented to face sliding surfaces of the driven member and the drive cam at least in a period which is a part of one rotation of the drive cam.Type: GrantFiled: October 23, 2008Date of Patent: February 22, 2011Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Toru Nishida, Kazuki Nagasawa, Yoshio Watanabe, Yoji Fukami, Toshiyuki Yanamoto
