Patent number: 8420188Abstract: A resin member fitting structure including a first resin member, which is a rectangular hollow tube, has at least one inner wall surface. A second resin member, which is a hollow or solid rectangular tube, has at least one outer wall surface fitted to the at least one inner wall surface of the first resin member. The inner wall surface of the first resin member and the outer wall surface of the second resin member come into contact with each other and define at least one set of fitting surfaces. The second resin member has a hygroscopic expansion coefficient that is smaller than that of the first resin member. The at least one fitting surface includes a plurality of recess-projection engagement structures spaced apart from each other in a circumferential direction that intersects a longitudinal direction of the first and second resin members.Type: GrantFiled: December 18, 2008Date of Patent: April 16, 2013Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Masaki Kawashima, Shinji Hasegawa, Giko Makino

Publication number: 20090058597Abstract: A vehicle security system for improving convenience without lowering the security level. The vehicle communication system includes a plurality of portable devices and a communication controller, which communicates with the portable devices and controls a vehicle. The communication controller includes a first transmitter circuit, which transmits a first wireless signal within an area near the vehicle, a second transmitter circuit, which transmits a second wireless signal within an area in the passenger compartment of the vehicle, and a communication control unit, which controls at least the closing of a door lock. When a door lever is operated in a state in which the door lock is closed, the communication control unit closes the door lock when one of the portable devices is located near the vehicle and keeps the door lock closed when none of the portable devices is located near the vehicle.Type: ApplicationFiled: September 4, 2008Publication date: March 5, 2009Applicant: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Toshimasa SHIBAGAKI, Masaki KAWASHIMA

Patent number: 5027679Abstract: A tubular arrangement the front end of which defines a fastener outlet is extendably and contractably mounted to a fastener driver body. A drive bit is mounted within the tubular arrangement. A fastener feeder is mounted to the tubular arrangement and contains a pair of fastener guiding plates opposite each other with a predetermined distance sufficient to pass a strapped fastener assembly. One of the fastener guiding plates defines a fastener passage opening for feeding a fastener into the tubular arrangement through a fastener feed hole defined in the side wall of the tubular arrangement. A fastener feed mechanism with a feed roller intermittently engaging and advancing the strap is provided. A fastener separation element of a fastener separation mechanism passes into and out of the fastener passage clearance, presses the fastener and separates it from the strap when the fastener separation element extends out of the fastener passage clearance, to feed the separated fastener into the tubular arrangement.Type: GrantFiled: March 6, 1990Date of Patent: July 2, 1991Assignee: Masaki KawashimaInventors: Masaki Kawashima, Kouichi Miyagaki

Patent number: 5005699Abstract: A strapped fastener assemblage for an automatic fastener driver includes a pair of connecting straps made of paper, each of which has a plastic film laminated onto one surface of the connecting strap. The plastic-film-side surfaces of the connecting straps are in contact with each other. A plurality of pin-like fasteners are arranged in parallel to one another with a predetermined spacing and each of the fasteners extend transversely of and between the connecting straps; and a plurality of fastener retainers are defined by a pair of heat-sealed portions in the connecting straps extending transversely of the connecting straps, and the fastener retainer will retain a corresponding one of the fasteners.Type: GrantFiled: December 6, 1988Date of Patent: April 9, 1991Assignee: Masaki KawashimaInventors: Masaki Kawashima, Kouichi Miyagaki
