摘要:
Aluminum alloy composite materials for brazed heat exchangers are described, which comprise an Al core alloy essentially consisting of predetermined amounts of Si, Mg, Cu and at least one element selected from Mn, Cr and Zr, the balance being Al and inevitable impurities, and an Al alloy clad layer formed on one side of the core alloy which is in contact with an aqueous heat transfer medium. The clad layer has a thickness 3-20% based on the thickness of the composite material and a less-noble corrosion potential of 20-100 mV than the core alloy. A filler alloy may be formed on the other side of the core alloy.

摘要:
An aluminum-base brazing alloy containing essentially up to 2 wt % of Cu, 0.01 to 0.08 wt % of Ti, and the balance of Al and unavoidable impurities, with or without at least one component selected from the group consisting of 0.01 to 0.5 wt % of Zr, 0.05 to 0.5 wt % of Mn and 0.05 to 0.5 wt % of Cr.
摘要:
Surface-treated Al or Al alloy materials which excel in adhesive property, formability, weldability, phosphatability, paint adhesion, and post-painting corrosion resistance are provided by forming a coated layer containing Zn and Fe or one or more of Si oxides, Al oxides and Al hydroxides together therewith, on the surface of Al or Al alloy base. The surface-treated Al or Al alloy materials are useful as metallic material to be painted and used after press forming and other processing, spot or laser welding and phosphating, including panel materials for automobiles and other various vehicles, shells for housefold electrical apparatus, and building materials.

An aluminum alloy material having a surface suitable for zinc phosphate processing prepared by a process comprising the steps of (1) cleaning the aluminum alloy surface, and (2) forming a composite film layer comprising Zn metal, Ni or Mn metal, and silicon oxide on the surface of the aluminum alloy.
摘要:
A molten aluminum alloy processing method is intended use sludge produced by the zinc phosphate treatment of structures including those of aluminum alloys effectively as a flux for molten aluminum alloy processing. The flux contains 3 to 30% by mass fluorine-equivalent metal fluorides, 40 to 90% by mass metal phosphates (8 to 18% by mass P) and 50% by mass or below inorganic salts. The sum of contents of the inorganic salts and metal phosphates is 90% by mass or below.

A height H of the protrusions (3) is equal to or larger than 5 μm, and equal to or smaller than 32 μm, as well as at least one of a distance P between each two neighboring protrusions (3) and a distance W between each neighboring two of recesses (5) formed between the protrusions (3) is larger than the height H of the protrusions (3).
摘要:
Provided is a technique capable of allowing a person to perceive a fine relief on an object surface clearly. A tactile device of a tactile display slides above an object. The tactile device comprises three rods which are free to move up and down. Lower ends of the rods are in contact with a surface of the object. Upper ends of respective rods touch a palmar-side skin equivalent to positions of three joints of a first finger or a second finger. When the tactile device is slid, upper ends of respective rods move up and down in accordance with a surface relief of the object. In response to the movement of the tactile device, the three rods push three finger joint positions of the palmar-side skin with a stroke equal to a height of the relief.
摘要:
A control method for a power assist device provided with an operation handle, a force sensor that detects an operation force applied to the operation handle and an orientation of the operation force, a robot arm, and an actuator. When the orientation of the operation force is detected to be within a predetermined angle range with respect to a preset advancing direction of the operation handle, the actuator is controlled so as to move the operation handle along the advancing direction by employing only a component of the operation force along the advancing direction; and when the orientation of the operation force is detected to be outside the predetermined angle range, the actuator is controlled to move the operation handle by the operation force applied to the operation handle and the orientation of the operation force.
