Abstract: A cargo conveying device includes: a horizontal direction conveying section that conveys cargo in a horizontal direction, and that includes a transfer section at which cargo is transferred between the transfer section and a cargo handler; a height adjusting section that adjusts a vertical direction height of the transfer section; and a control section that, at a time at a time at which cargo is transferred between the transfer section and a cargo handler, operates the height adjusting section, and adjusts the vertical direction height of the transfer section.

Abstract: A lens barrel 10 comprises a fourth lens group unit 20, cam pins 22a and 22b, a biasing pin 23, a cutout portion C1, a substantially cylindrical first lens group unit 13, and a plurality of rectilinear guide portions 25. The fourth lens group unit 20 has a substantially cylindrical main body portion 21 that holds a lens L4a, etc. The cam pins 22a and 22b are provided to the fourth lens group unit 20, protrude in the radial direction, and engage in the cam grooves 14b of the cam frame 14. The biasing pin 23 is provided to the fourth lens group unit 20, is supported so as to bias in the radial direction, and engages in the cam groove 14b. The cutout portion C1 is formed by cutting out the portion of the main body portion 21 of the fourth lens group unit 20 opposite the biasing pin 23 in the direction of the optical axis. The main body portion 21 of the fourth lens group unit 20 is provided continuously in the circumferential direction, from the biasing pin 23 to the cam pins 22a and 22b.

Abstract: A method for producing a sealed battery, capable of firmly joining a battery case and a sealing cover, includes injecting an electrolytic solution into the battery case through the liquid inlet, and after the injecting, welding the battery case and the sealing cover by irradiating and linearly scanning a laser beam on a welding area across the battery case and the sealing cover, while the liquid inlet is closed with the sealing cover. The laser beam has a beam profile including a first beam capable of vaporizing the electrolytic solution and oil, which exist on the surface of the welding area, and a second beam enabling keyhole welding on a removal portion of the welding area, from which at least part of the electrolytic solution and at least part of the oil have been removed by irradiation of the first beam.

Abstract: A heat exchanger has a flat tube (10) having a curved portion (13). A part of the curved portion (13) is formed by overlapping an outer rim (22) on an inner rim (21). The inner rim (21) has a small curvature region (102). The small curvature region (102) is inclined to a flat plate portion (11), and is defined by a radius larger than a difference between a half of a thickness of the flat tube (10) and a thickness of the outer rim (22). The small curvature region (102) is not beyond a center line (C1) in a thickness of the flat tube (10). The outer rim (22) extends beyond the center line (C1). The outer rim (22) has an end face (22a) placed on the small curvature region (102). The flat tube (10) has flared portions (15, 16) expanded at insertion holes (54).

Abstract: A cylindrical member of a tube for a heat exchanger is made of a pair of flat plate portions, and a pair of curved portions for connecting the pair of flat plate portions to each other. One of the pair of curved portions constructs a bonded portion in which an outer wall portion and an inner wall portion are bonded to each by brazing in a state where the outer wall portion and the inner wall portion overlap each other. The inner wall portion has a portion opposite to the outer wall portion put into close contact with the outer wall portion and is bonded to the one flat plate portion in a state where a tip end portion of the inner wall portion opposite to the one flat plate portion is separated from the one flat plate portion.

Abstract: A heat exchanger includes a plurality of tubes in which a thermal fluid flows, and a tank located at one longitudinal end portion of each tube and is brazed to the longitudinal end portions of the tubes to communicate with the tubes. The tank and the tube are respectively made of clad material plates in each of which a brazing material is clad on at least one surface of a core material. The brazing material of the tank and the brazing material of the tube respectively include Si content. Furthermore, a rate of the Si content in the brazing material of the tank is lower than that in the brazing material of the tube, and is in a range larger than 0% and equal to or smaller than 6%. Thus, meltage of the tube due to molten brazing material can be reduced during brazing of the tube and the tank.

Abstract: Highly-pure water is stored into a storage tank 46 by reducing an impurity-ion content to not greater than a specified rate by removing impurity ions via a device 43, for manufacturing pure water, containing ion-exchange resin, and by reducing a dissolved-oxygen content to not greater than a specified rate by heating-deaerating with a heater 44 and reducing the pressure during storage in the storage tank 46. Highly-pure water to be stored is injected from a gun 10 into a vessel body 1 while detecting a flow-rate via a mass-flow meter 53. Therefore, a highly-accurate amount of water, with high purity, can be filled into the vessel body 1.

Abstract: Each of specific rollers which corresponds to one of the grooves is disposed in a circumference of the metal pipe at equal intervals and is pressed against the periphery of the metal pipe 10, thereby forming a plurality of the grooves at the same time. Because each of the grooves is formed by a specific forming roller, a plurality of the grooves can be formed separately, and the material of the wall between the grooves is prevented from being drawn. Thus, the grooves can be formed into a desired shape.

Abstract: An expandable, powder coating composition is disclosed which includes (a) a thermoplastic resin containing a hydroxyl group-containing polymer, (b) a cross-linking agent containing a polyisocyanate compound which is capable crosslinking the thermoplastic resin, (c) a blowing agent, and (d) a mixture of a solid plasticizer such as triphenyl phosphate and a liquid plasticizer such as dioctyl phthalate.

Abstract: An expandable, powder coating composition is disclosed which comprises (a) a thermoplastic resin containing a copolymer of ethylene with vinyl acetate, (b) a cross-linking agent containing an organic peroxide, (c) a blowing agent, and (d) an organic plasticizer. Powder coating of a surface of a tube or box to be used in air conditioners with the coating composition can give a heat-insulating, foamed sheath or lining over the surface.
