Patent number: 9153402Abstract: A cutter includes a stopper with which a blade after cutting a harness with a cutting portion collides and stops. The blade includes a flexible guide portion which protrudes further in a forward direction of the blade than the cutting portion.Type: GrantFiled: November 28, 2011Date of Patent: October 6, 2015Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Tetsuya Ukon, Teruaki Tsuchiya, Futoshi Okugawa

Publication number: 20140326122Abstract: A cutter prevents movement of a harness being cut. The cutter includes: a first cylindrical member and a second cylindrical member whose axial ends face each other, with a predetermined distance therebetween, and sandwich the harness in the axial direction; and a blade accommodated in the first cylindrical member to be slidable in the axial direction and including a cutting portion on a front side and a pusher on a back side. The first cylindrical member includes a back side tapered portion and a front side tapered portion at which an inner diameter of the first cylindrical member on an inner surface where the pusher slides is gradually reduced from a back side to a front side.Type: ApplicationFiled: November 28, 2012Publication date: November 6, 2014Applicant: Daikin Industries, Ltd.Inventors: Tetsuya Ukon, Teruaki Tsuchiya, Futoshi Okugawa

Patent number: 8653386Abstract: A blade (11), which includes a cutting portion (21) and an insulating portion (22), is used as a blade (11) of a cutting apparatus (10). The cutting portion (21) is made of a metal, and has a blade portion. The insulating portion (22) is formed by an insulating member, and forms a part that adjoins the blade portion in a direction opposite to an advance direction of the blade (11). The cutting apparatus (10) is configured so that, when cutting a current-carrying member (15), the blade (11) advances until the insulating portion (22) contacts cut faces of the current-carrying member (15) after the cutting portion (21) cuts the current-carrying member (15).Type: GrantFiled: September 3, 2008Date of Patent: February 18, 2014Assignee: Daikin Industries, Ltd.Inventors: Tetsuya Ukon, Teruaki Tsuchiya, Futoshi Okugawa

Publication number: 20130263715Abstract: A cutter includes a blade and a case. A harness is placed across a second hole. A second inner cylinder member has a back-side inner wall extending from the harness toward a first inner cylinder member, for guiding a cutting portion to the harness.Type: ApplicationFiled: November 28, 2011Publication date: October 10, 2013Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Tetsuya Ukon, Teruaki Tsuchiya, Futoshi Okugawa

Publication number: 20130255464Abstract: A cutter includes a blade member configured to cut a current-carrying member by an edge portion, a gas generator configured to move the blade member toward the current-carrying member, a receiving member arranged on a side opposite to the blade member relative to the current-carrying member and defining a receiving surface for receiving the current-carrying member upon cutting thereof, and a stopper configured to restrict forward movement of the blade member such that the blade member stops at a predetermined position. An insulating protective film softer than the current-carrying member is formed on a surface of the edge portion, inner surfaces of guide portions formed in a front end portion of the blade member, and the receiving surface of the receiving member.Type: ApplicationFiled: November 28, 2011Publication date: October 3, 2013Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Tetsuya Ukon, Teruaki Tsuchiya, Futoshi Okugawa

Patent number: 8522539Abstract: Disclosed is a gas pressure actuator whose actuator body has a cylinder, a piston and a gas generator in which a powder is loaded, and the gas generator is positioned at an end portion of the cylinder. The gas generator injects a high pressure gas into the cylinder by the combustion of the powder, thereby moving the piston. The actuator body is provided with a coating which covers the entire actuator body from outside. The coating is a resin coating having electrically insulating, waterproof, and dustproof characteristics.Type: GrantFiled: September 4, 2008Date of Patent: September 3, 2013Assignee: Daikin Industries, Ltd.Inventors: Tetsuya Ukon, Teruaki Tsuchiya, Futoshi Okugawa
