Patent number: 11986878Abstract: When molding surfaces (50A) of a pair of dies (50) are to be cleaned by air-blowing, air is blown towards the molding surfaces (50A) from blowing nozzles (22A) of a cleaning blowing function portion (22) while a moving body (16) is reciprocatingly moved by driving force of a driving mechanism (18). When a parting agent is to be applied to the molding surfaces (50A) of the pair of dies (50), the mold release agent is jetted out towards the molding surfaces (50A) from spraying nozzles (24A) of a parting agent application function portion (24) while the moving body (16) is reciprocatingly moved by the driving force of the driving mechanism (18). In both of these situations, at the same time as the treatment of the molding surfaces (50A), a cleaning brush (32) reciprocatingly moves together with the moving body (16) and sweeps a device floor surface (12).Type: GrantFiled: April 24, 2019Date of Patent: May 21, 2024Assignees: Sintokogio, Ltd., Toyota Jidosha Kabushiki KaishaInventors: Youhei Noguchi, Koji Sakou, Hirotaka Kurita, Takashi Nagaya, Hirotsune Watanabe, Katsutoshi Okumura

Patent number: 7089671Abstract: A circular saw (1) includes a base plate (2) and a saw blade assembly (3) including a lower blade guard (9) for covering a saw blade (6). The blade guard includes a sleeve portion (10) rotatably fitted on a bearing box (8) coupled to the saw blade assembly and a sectoral portion (11) extending radially from the sleeve portion in the rear of the blade. A connecting bar (13) projects radially rearward from the sectoral portion. A spring (14) is stretched between the top of the connecting bar (13) and a lower rear portion of an upper blade guard (4) close to the base plate. When not in use, torque, generated as the product of the spring's tensile force and the perpendicular distance (S) from the line of action or the force to the axis of rotation (O), rotates the blade guard to a closed position.Type: GrantFiled: April 25, 2002Date of Patent: August 15, 2006Assignee: Makita CorporationInventors: Katsuji Haneda, Shingo Tsuchiya, Hirotaka Noguchi

Patent number: 6887106Abstract: A shielding connector has a female and male housings (30; 60), each of which has an inner housing (31, 61) that accommodates terminal fittings (20; 25). Metal shells (50, 80) are mounted on the peripheries of the inner housings (31, 61) and electromagnetically shield the female and male terminal fittings (20; 25) when the housings (30; 60) are connected. The metal shells (50; 80) are configured to achieve secure mounting, effective shielding and a small cross section. A detector (90) is provided to ensure complete connection and is configured to prevent inadvertent separation of the housings (30; 60).Type: GrantFiled: November 7, 2003Date of Patent: May 3, 2005Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Hirotaka Noguchi, Shiro Nishida

Patent number: 6764329Abstract: A waterproof resilient plug (20) has a trunk portion (11) to be brought into close contact with the inner circumferential surface of a terminal insertion hole (C) and a fixing portion (12) extending from the leading end of the trunk (11) and to be pressed against the outer circumferential surface of a wire (W) by insulation barrels (20a). The plug (20) is formed along its longitudinal axis with a wire insertion hole (13) that can be brought into close resilient contact with the outer surface of the (W). An inner diameter of the wire insertion hole (13) aligned with the fixing portion (12) is smaller than the one at the side of trunk (11), whereby the fixing portion (12) can be held strongly in close contact with the outer surface of the wire (W).Type: GrantFiled: December 2, 2002Date of Patent: July 20, 2004Assignee: Sumitomo Wiring Systems, Inc.Inventors: Hirotaka Noguchi, Masaaki Tabata, Masanori Wakui, Keiichi Itou

Patent number: 6572400Abstract: The invention improves the assembly operation of a connector provided with a detecting member. A female housing 20 is provided with a locking arm 33 capable of engaging with a locking protrusion 14 of a male housing 10. A detecting member 50 capable of moving in an anterior-posterior direction is attached to an upper face of this locking arm 33. The detecting member 50 has an operating member 53 joined to a posterior end of a main body 51 by a hinge 52. A finger engages from the posterior with the operating member 53 to push in the detecting member 50, this detecting member 50 being pushed in its direction of fitting in an inclined downwards direction. When the detecting member 50 is in a waiting position, the operating member 53 thereof is located above a posterior portion of the upper face of the locking arm 33. This posterior portion of the upper face of the locking arm 33 has a guiding inclined face 44 formed thereon, this guiding inclined face 44 being inclined downwards in the pushing-in direction.Type: GrantFiled: November 27, 2001Date of Patent: June 3, 2003Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Hirotaka Noguchi, Kenji Inoue
