Patent number: 11958125Abstract: A manufacturing method includes a joining step of abutting and joining an end surface of a tube main body and a projecting portion of a head member by frictional welding in a state in which a through hole of the tube main body and the projecting portion of the head member are fitted with a fitting clearance. In the joining step, flow material which is practically flowed from an end surface of the tube main body and the flange portion of the head member is filled in the fitting clearance from the root side until the tip portion is located within the range in the direction of the rotation axis, thereby joining between a non-contact portion and the tube main body and between an inclined inner peripheral surface of the tube main body and an outer peripheral surface of the projecting portion by the flow material.Type: GrantFiled: September 17, 2019Date of Patent: April 16, 2024Assignee: KYB CORPORATIONInventor: Yasuyuki Nagai

Patent number: 11534852Abstract: A manufacturing method for manufacturing a cylinder tube includes a joining step of joining a tube main body and a head member by friction welding by abutting an end surface of the tube main body and a flange portion of the head member in a state in which a through hole of the tube main body and a projecting portion of the head member are fitted to each other so as to form a predetermined clearance. In the joining step, a non-contact portion of the flange portion of the head member facing the clearance is joined to the tube main body by heating the non-contact portion with friction heat generated by relative rotation between the tube main body and the head member.Type: GrantFiled: March 14, 2018Date of Patent: December 27, 2022Assignee: KYB-YS CO., LTD.Inventor: Yasuyuki Nagai

Patent number: 7718843Abstract: An iron powder for decomposition of organic chlorinated compounds, comprising from 0.03 to 0.5% by weight of Ni and from 0.005 to 5% by weight of carbon, wherein particles having a particle size of less than 53 ?m occupies less than 40% by weight, is used. It is particularly preferable that Ni, carbon and iron are partially alloyed. When the iron powder for decomposition is used by mixing with, for example, an Ni-free iron powder, the total Ni content can be reduced without deterioration of decomposition performance to organic chlorinated compounds. The iron powder has high decomposition performance in the treatment of a solid such as soil.Type: GrantFiled: July 17, 2007Date of Patent: May 18, 2010Assignee: Tosoh CorporationInventors: Yoju Shimizu, Yasuyuki Nagai

Patent number: 7178367Abstract: An apparatus for bend-shaping a glass sheet is disclosed, which comprises a heating furnace, a plurality of in-furnace beds disposed within the heating furnace, at least one out-furnace bed disposed externally of the heating furnace proximately to an outlet of the heating furnace, and an elevating mechanism disposed below that one of the in-furnace beds which is positioned proximately to the outlet and the out-furnace bed. The in- and out-furnace beds have upper surfaces curved transversely and capable of jetting air to floatingly support a glass sheet. For producing a dual curved glass sheet, the elevating mechanism is operated to elevate opposed ends of the one in-furnace bed and the out-furnace bed so that these beds jointly form a hill. For producing a single-curved glass sheet, the elevating mechanism is operated to lower the opposed ends of those beds to their original flat positions.Type: GrantFiled: February 23, 2004Date of Patent: February 20, 2007Assignee: Nippon Sheet Glass Company, LimitedInventors: Seiichiro Honjo, Takeshi Yabuno, Yasuyuki Nagai
