Patent number: 9751538Abstract: Provided is a sound absorbing panel that can satisfy the heat resistance properties and melting/dripping resistance properties required inside of a railway vehicle. A pier sound absorbing panel includes five sheets of first through fifth glass cloths that are stacked on an aluminum base plate. The edge section of the fifth glass cloth is affixed to the rear surface of the base plate using an adhesive, and the first through fourth glass cloths are fastened using staples. In other words, the first glass cloth and the base plate are fixed using an adhesive, and this adhesive is prevented from melting by the five sheets of the first through fifth glass cloths. The adhesive that fixes the edge section of the fifth glass cloth at the other surface of the base plate is prevented from melting by the five sheets of the first through fifth glass cloths and the base plate.Type: GrantFiled: October 31, 2013Date of Patent: September 5, 2017Assignees: CENTRAL JAPAN RAILWAY COMPANY, NIPPON SHARYO, LTD.Inventors: Yukio Takahashi, Hiroki Tsunoda, Yuya Futamura, Koichi Hayashi, Naoya Ozawa, Masaki Hase, Naoyuki Maruyama

Patent number: 9663119Abstract: Provided are a railroad vehicle that makes it possible to maintain the air tightness of a door and a plug door for a railroad vehicle. A second rail is provided parallel to a first rail in the longitudinal direction of a vehicle body above the leading edge side (door side) of a plug rail. The second rail supports the leading edge side of the plug rail. As a result, both edges of the plug rail are supported by the first rail and the second rail. Dangling of the leading edge side of the plug rail is thus prevented even when the plug distance (the distance that the door moves in the vehicle body width direction) is long. In this way, it is possible to block the doorway without leaving a gap using the door and to maintain the air tightness of the door.Type: GrantFiled: October 31, 2013Date of Patent: May 30, 2017Assignees: CENTRAL JAPAN RAILWAY COMPANY NIPPON SHARYO, LTD., NIPPON SHARYO, LTD., NABTESCO CORPORATIONInventors: Yukio Takahashi, Hiroki Tsunoda, Soshi Kawakami, Yuya Futamura, Tomoyuki Fukunaga, Tadahiro Mitsuda, Genta Sakaki

Patent number: 9403540Abstract: A railroad vehicle that moves a door to an airtight position and maintains air tightness of the door without increasing the size of a cylinder device; and a plug door for a railroad vehicle. When a door moves to a position, a piston extends in the vehicle width direction, a pressing member is contacts the inner surface of the door, and the door is moved toward a door frame. An auxiliary pressing device brings the piston into perpendicular contact with the inner surface of the door making it is possible to efficiently move and press the door without increasing the size of a cylinder device even when the door must be moved across a distance to arrive at an airtight position. The main pressing device is used to press the door toward the door frame.Type: GrantFiled: October 31, 2013Date of Patent: August 2, 2016Assignees: CENTRAL JAPAN RAILWAY COMPANY, NIPPON SHARYO, LTD., NABTESCO CORPORATIONInventors: Yukio Takahashi, Hiroki Tsunoda, Soshi Kawakami, Yuya Futamura, Tomoyuki Fukunaga, Tadahiro Mitsuda, Genta Sakaki

Publication number: 20150321677Abstract: A railroad vehicle that moves a door to an airtight position and maintains air tightness of the door without increasing the size of a cylinder device; and a plug door for a railroad vehicle. When a door moves to the position as indicated by the two-dot/dash line in FIG. 1, a piston extends in the vehicle width direction, a pressing member is contacts the inner surface of the door, and the door is moved toward a door frame. An auxiliary pressing device brings the piston into perpendicular contact with the inner surface of the door making it is possible to efficiently move and press the door without increasing the size of a cylinder device even when the door must be moved across a distance to arrive at an airtight position. The main pressing device as indicated in FIGS. 5(a)-5(b) is used to press the door toward the door frame.Type: ApplicationFiled: October 31, 2013Publication date: November 12, 2015Inventors: Yukio TAKAHASHI, Hiroki TSUNODA, Soshi KAWAKAMI, Yuya FUTAMURA, Tomoyuki FUKUNAGA, Tadahiro MITSUDA, Genta SAKAKI
