  • Patent number: 11058817
    Abstract: An expansion/compression mechanism of a piston rod assembly is composed of a bush shaft, a first cylindrical piston rod that is screwed with the bush shaft, a second cylindrical piston rod that is screwed with the first piston rod, and a piston rod holding member for housing the bush shaft and these piston rods. Therefore, the piston rods move linearly in multiple stages.

  • Publication number: 20200377728
    Abstract: Composite resin granules 5 contain a binder resin 2 and a thermally conductive filler. The thermally conductive filler includes a non-anisotropic thermally conductive filler 3 and an anisotropic thermally conductive filler 4. The composite resin granules containing the binder resin and the thermally conductive filler are formed into a spherical shape. The particles of the anisotropic thermally conductive filler 4 are oriented in random directions. A thermally conductive rein molded body 6 of the present invention is obtained by compressing the composite resin granules 5. Thus, the present invention provides the thermally conductive resin molded body that has relatively high thermal conductivities in the in-plane direction and the thickness direction, well-balanced directional properties of thermal conduction, and a low specific gravity, the composite resin granules suitable for the thermally conductive resin molded body, and methods for producing them.

  • Patent number: 9289871
    Abstract: To prevent entrance of swarf or cutting oil from a workpiece recovery opening, in a workpiece recovery unit, a cover 21 which covers an upper side and a lateral side of a workpiece recovery opening 19 opening in an upper side of a workpiece recovery section 18 disposed lateral to a holder 13 which holds a processed workpiece 1?, a workpiece transport path 23 from an entrance 22 opening in a lower side provided in the cover 21 to the recovery opening 19 is formed in a step-like shape, the holder 13 is supported so as to be movable in an up-and-down direction and a right-and-left direction, the workpiece 1? is moved along the transport path 23 by the holder 13, and is transported to the upper side of the recovery opening 19 from the entrance 22 so as to be recovered in the recovery opening 19.
