  • Patent number: 10322211
    Abstract: Biphasic self-setting calcium phosphate (SSCP) used for bone graft material and dental material applications having shape formability, shape retentivity, and bone replacement properties in addition to biocompatibility, safety, non-infectiousness, and absence of outflow, wherein the work time for forming the shape of a kneaded material obtained by kneading biphasic SSCP powder and biphasic SSCP liquid is controlled. A method for controlling the work time for forming the shape of biphasic SSCP in which the moldable work time from the start of kneading to the setting of the kneaded material is adjusted to within a range of from 10 seconds to 600 seconds by kneading a biphasic SSCP powder and biphasic SSCP liquid, the biphasic SSCP powder comprising tetracalcium phosphate and ?-tricalcium phosphate and the biphasic SSCP liquid comprising a phosphoric acid aqueous solution containing a calcium component.

  • Patent number: 6601627
    Abstract: A device 1 for continuously manufacturing an FRP square pipe includes a core 10 having a long length for laminating prepreg sheets thereto, and prepreg sheets are supplied from prepreg-sheet laminating devices 20, 30, 40, and 50 to said core 10 covered with a release film, said laminated sheets laminated into the shape of a square pipe. Said core 10 has an outer diameter size smaller than the inner diameter size of the square pipe to be manufactured. A pre-expansion device 80 expands said laminated prepreg sheets to the shape of a square pipe having a predetermined inner diameter size, and a hot press device 100 heats and pressurizes the pipe. The pipe is then additionally heated in a postcure furnace 110 to complete the forming process. A pulling device 130 arranged downstream of a cramp device 120 pulls out said square pipe intermittently. A cutter not shown cuts said square pipe to produce the desired product.

  • Patent number: 6191395
    Abstract: A heating roller 10 comprises a surface layer 157 formed of a prepreg material including carbon fibers having a high tensile strength and a high elastic modulus, and a heating unit 153 mounted in the inner area of the surface layer and communicated to a power supply unit 30 formed of a prepreg material including carbon fibers having a high electric resistance. A metal material working as an electrode 20 communicated to the power supply unit 30 and the heating unit 153 is mounted to both ends of the heating roller 10. The electric resistance of the heating unit 153 is adjusted either by changing the thickness (number of laminated layers) of the prepreg material including carbon fibers, or by adjusting the mounting angle of the carbon fibers inside a prepreg material being laminated and the angle of the carbon fibers inside another prepreg material being laminated.
