Publication number: 20240175823Abstract: Provided is a method for inspecting surface deformation of a structure which enables easy measurement of the amount of deformation of the surface of a structure protection sheet attached to the surface of a structure such as concrete. The method for inspecting surface deformation of a structure includes: identifying a structure protection sheet attached to a surface of a structure using an individual identification means; digitally photographing a surface of a resin layer on an outermost surface of the structure protection sheet using a digital photography means; measuring a dimension of the surface of the resin layer based on image data obtained in the digital photography using a dimension measuring means; and calculating an amount of deformation of the surface of the resin layer based on data of the measured dimension using a calculation means.Type: ApplicationFiled: March 25, 2022Publication date: May 30, 2024Applicant: KEIWA IncorporatedInventors: Satoru Tani, Takahiro Tsuji, Yuki Matsuno, Kosuke Yasuno, Satoshi Shiba, Yu Kariya

Publication number: 20240157465Abstract: A method for manufacturing a shaft, whereby a hollow shaft in which linking members are joined at both ends of a cylindrical member (a pipe member) can be manufactured more efficiently. A method for manufacturing a shaft in which linking members are provided to end parts of a cylindrical member, wherein the method comprises: a preparation step for preparing the cylindrical member, in which male threaded portions are formed at the end parts; a screwing step in which the linking members, which have female threaded portions to be screwed onto the male threaded portions, are screwed onto the male threaded portions; and a diffusion-joining step in which opposing end surfaces of the linking members and the cylindrical member are heated in a state of being pressed against each other by the tightening produced by the screwed-on linking members, and the opposing end surfaces are diffusion-joined.Type: ApplicationFiled: September 27, 2021Publication date: May 16, 2024Applicant: SANJO MACHINE WORKS, LTD.Inventors: Hiroyuki KARIYA, Takahiro SEKINE, Fumihiko HATTORI, Kazushi GOI, Ryo KUROSAWA

Patent number: 6286839Abstract: A ring seal contains a core made from an elastic organic polymer and a metal jacket having a U-shaped sectional shape, which jacket surrounds the core to prevent transfer of a substance generated from the core into the sealed space. The seal of the present invention does not release a foreign material into the sealed space, nor does it require a great force for clamping. Accordingly, it is useful as a vacuum seal that achieves miniaturization and reduced weight of a vacuum apparatus. In particular, by making the sectional shape of the metal jacket a U shape, the core can be easily detached and attached for fitting after forming the jacket, and the inside of the jacket can be washed easily.Type: GrantFiled: October 30, 1998Date of Patent: September 11, 2001Assignee: Mitsubishi Cable Industries, Ltd.Inventors: Takayoshi Mitsui, Takahiro Kariya
