  • Patent number: 9671264
    Abstract: Provided is an ultrasonic flow switch which can be stably mounted on pipes. A casing part which integrally or independently holds the ultrasonic wave elements is mounted on an outer surface of the pipe by a clamp part. An acoustic couplant which is formed of a soft elastic body is pressed to an outer surface of the pipe such that at least one of the first and second ultrasonic wave elements is acoustically coupled to the pipe. A collapsing amount of the acoustic couplant at a portion where the collapsing amount of the acoustic couplant caused by the pipe is the largest is restricted by a collapsing amount restricting part.

  • Publication number: 20090152898
    Abstract: To provide a pipe member composed of a small-diameter metal pipe and a large-diameter metal pipe integrated via a double pipe structure part. A diameter expanding punch 12 is press-fitted into a small-diameter pipe 3 through a large-diameter pipe 2, thereby integrally expanding the diameter of the small-diameter pipe 3 and the large-diameter pipe 2. As the diameter of the small-diameter pipe 3 is expanded, the longitudinal dimension of an expanded part 3b is shortened, and the tip end of the expanded part 3b of the small-diameter pipe 3 is spaced apart from a step part 2c of the large-diameter pipe 2. In this state, the large-diameter pipe 2 and the small-diameter pipe 3 are displaced with respect to each other in the longitudinal direction.

  • Patent number: 6907664
    Abstract: A method for manufacturing a fuel inlet having a good sealing property and a screw structure formed in a precise position involves expanding one end of a long-length stainless pipe (metal pipe) using a cored bar, the tip of the expanded portion which becomes non-uniform as a result of the expanding step is cut off, a screw structure is formed in the expanded portion by using a punch, the tip of the expanded portion which becomes non-uniform as a result of the screw structure forming step is cut off, and thereafter curl forming is conducted to the end of the expanded portion which becomes uniform by using a die so as to provide a seal portion.

  • Patent number: 6817382
    Abstract: A metal pipe 11 of a smaller diameter engages a metal pipe 13 of a larger diameter to provide a double-pipe structure in a predetermined area in the longitudinal direction, wherein the diameter of the two pipes 11 and 13 of the double-pipe structure section is integrally expanded using a pipe expansion technique. By making a predetermined section of the pipe member a double-pipe structure, it is possible to provide the strength and rigidity necessary for each section. It is also possible to join the two pipes by expanding the diameter of each pipe at the double-pipe structure section. By forming a section where high strength is not required by a pipe of a smaller diameter, it is possible to lighten the pipe member. Materials for the pipes 11 and 13 are carbon steels for machine structural use. If aluminum is used for the metal pipe 11 of a smaller diameter, it is possible to further lighten the pipe member.

  • Patent number: 6810573
    Abstract: In manufacturing a fuel inlet, bulge forming and bend processing are conducted to a stainless pipe which will serve as an inlet pipe. Next, one end of the stainless pipe is eccentrically expanded, and the hardened portion is removed. After the pipe expanding step is finished, boring processing is conducted so that a breather pipe can be inserted into the inlet pipe, a guide is spot-welded to the inside of the eccentrically expanded portion, and a screw structure is formed. The inlet pipe and the breather pipe are degreased and cleaned as a pretreatment for brazing, and brazing is conducted by using BAg-4 (Low-temperature brazing material) at a temperature of 750-850° C. Removing of the flux and cleaning are conducted as a post-treatment for brazing, and finally coating is conducted.

  • Patent number: 5517706
    Abstract: A sofa-bed is comfortable to use in a bed mode and its backrest can be put away in the position so as not to be an obstacle. A movable backrest of the sofa-bed 10 is divided into two movable half backrests 20,22 or a right movable half backrest and a left one, and the sofa-bed can be changed between the bed mode and the sofa mode by positioning movable half backrests 20.22 individually in first positions substantially above a head board 16 and a foot board 18 or in second positions appropriately parallel to an center line extending in longitudinal direction of the sofa bed.
