Provided is a platform screen door device capable of reducing total weight of the whole device and securing sufficient strength and durability thereof. The platform screen door device includes a door case provided on a platform; and a sliding door moving in and out of the door case. At least one of the door case and the sliding door includes a frame formed by integrating horizontal door case frame members and vertical door case frame members disposed orthogonally relative to each other, or by integrating horizontal door frame members and vertical door case frame members disposed orthogonally relative to each other, through fastening members using bolts and fixing members using adhesive or the like, supplemental for joint strength of the fastening members using the bolts.

A friction stir welding (FSW) method and apparatus are provided by which power needed for FSW is reduced and a compact FSW tool can be used. In the FSW method, metal members are lapped one on another and a rotating probe of an FSW tool is inserted into a contact portion of the metal members. The contact portion is softened by frictional heat and stirred by the probe so that the metal members are welded together. A portion of the metal members surrounding the probe is heated by a heater.
摘要:
A machining method for an integrated piping plate, for example, composed of a plurality of plates joined together, and in which an instrument and a component constituting an apparatus, or the instrument, or the component are or is disposed on one surface or both surfaces of the integrated piping plate, and the instrument and the component, or the instrument, or the component are or is connected by fluid channel grooves formed in joining surfaces of the plates, and communication holes formed in the plates. The machining method welds the joining surfaces of the plates around the entire periphery of the fluid channel grooves, for example, by an FSW welding machine, to join the plates. Compared with joining of the plates by an adhesive, the machining method can increase the durability of the plate joining portion and increase pressure resistance. Also, the method can increase work efficiency and further downsize the integrated piping plate.

A transfer system includes an air table, and a linear motor cooperating with the air table to float and move a pallet. The transfer system is designed to allow for a small radius of curvature for each turning section of the air table. Ball valves of the air table are openable upon contact with a pallet to apply air under pressure to a pallet. A linear motor is adapted to move the floating pallet, and guides are provided to guide the moving floating pallet. The pallet includes a pallet body made of a light material, and an external load part made of metal. The external load part has a lower surface projecting slightly from the lower surface of the pallet body. Guides are mounted to the outer periphery of the pallet body. A linear motor secondary conductor is mounted to the lower surface of the pallet body.

In a heat exchanger plate, machine time required for processing can be shortened, production costs can be reduced, and a penetration bead of a weld can be prevented from intruding into a flow channel, thereby preventing the weld from deforming a cover section. The heat exchanger plate comprises: a flat main body on a surface of which is formed at least one first groove having a rectangular cross-sectional shape; and a cover which has substantially the same shape as the first groove in plan view and which is formed such that when embedded in the first groove, a rear face thereof contacts a bottom of the first groove and opposite side faces thereof contact opposite side faces of the first groove, and a surface thereof is substantially flush with that of the main body, wherein there is provided a second groove formed extending along the opposite side faces at a center of the rear face, and the cover is joined to the main body by friction stir welding.
