  • Patent number: 10442172
    Abstract: A processing apparatus of a stack is provided. The stack includes two substrates attached to each other with a gap provided between their end portions. The processing apparatus includes a fixing mechanism that fixes part of the stack, a plurality of adsorption jigs that fix an outer peripheral edge of one of the substrates of the stack, and a wedge-shaped jig that is inserted into a corner of the stack. The plurality of adsorption jigs include a mechanism that allows the adsorption jigs to move separately in a vertical direction and a horizontal direction. The processing apparatus further includes a sensor sensing a position of the gap between the end portion in the stack. A tip of the wedge-shaped jig moves along a chamfer formed on an end surface of the stack. The wedge-shaped jig is inserted into the gap between the end portions in the stack.

  • Publication number: 20190017203
    Abstract: Provided is a method for manufacturing a fishing net formed from a plastic net that can be handled by winding or folding although the net has plastic rigidity. The fishing net is manufactured by (1) a step of preparing a multifilament yarn formed by bundling a plurality of core-sheath type composite filaments, in each of which a core component is made of polyethylene terephthalate and a sheath component is made of polyolefin, (2) a step of preparing a yarn thread obtained by paralleling a plurality of the multifilament yarns, (3) a step of twisting or braiding four yarn threads 11, 12, 13, 14 to obtain a net constructed with strands 1 and intersections 2, (4) a step of heat-treating the net under without pressure to melt the sheath component of the yarn threads 11, 12, 13, 14 constituting the strands 1 and the intersections 2, followed by solidifying, thus obtaining a plastic net, and (5) a step of forming the fishing net using the plastic net.

  • Patent number: 10006572
    Abstract: An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.

  • Patent number: 9789401
    Abstract: A game device controls a first virtual camera and a second virtual camera so that the first virtual camera and the second virtual camera are situated within an object space to be point-symmetrical, line-symmetrical, or plane-symmetrical with respect to a reference point, a reference line, or a reference plane that is defined by a first position linked to a first character and a second position linked to a second character. The game device determines whether to display the object space photographed by the first virtual camera or the object space photographed by the second virtual camera as a game image based on a selection instruction issued by a player.
