The present invention is a cooling plate including a groove, which becomes a passage of a coolant, inside a body, wherein one or more fins are provided inside the groove, wherein the groove is covered with a lid having width larger than the groove, wherein the lid is joined to the body by friction stir welding, and wherein a weld bead formed by: the joining is outside the passage, and the weld bead formed by the joining is formed within the body and further, is characterized by a manufacturing method of a cooling plate that has a first groove, which becomes a passage of a coolant, and a second groove, which has width larger than the first groove and receives a lid on the first groove, inside a body, receives the lid on the second groove, and is joined to the body, the manufacturing method of a cooling plate wherein, while the lid and the body are joined together by the friction stir welding owing to insertion of a-rotation tool having a shoulder and a pin, the joining is performed so that a weld bead formed by the joining may become out of the passage, and furthermore, is characterized in that a target for sputtering is joined to the cooling plate.

The invention provides a friction stir welding apparatus and method and a processing apparatus and method, which are not easily affected by deformations of a work being processed. The friction stir welding apparatus inserts a rotating tool into the work and moves the rotating tool relative to the work to join members of the work. The friction stir welding apparatus and method and the processing apparatus and method of the invention, the latter cutting or grinding the work with a rotating cutter or grindstone, comprises controlling a relative distance between the tool, cutter or grindstone and the work under the joining or processing operation or an insertion depth so that the load factor or electric current of a spindle motor for rotating the tool, cutter or grindstone is within a predetermined range, and a controller therefor.

The disclosure is concerned with a thermal land machine which comprises a heat resistant wall for confining a chamber; a heat resistant composite structure disposed in the chamber and in contact with a hot flowing gas; and an apparatus for introducing the hot gas toward the surface of the composite structure. The composite structure including a heat resistant substrate and a continuous refractory coating formed on the substrate and made of a ceramic material. The refractory coating includes at least two layers in a laminated structure each having fine cracks substantially extended in the direction of the thickness of each of the layers and filled with a refractory material in such a manner that the filled cracks in one layer are disconnected with the filled cracks in the adjacent layer. Therefore, the hot gas cannot permeate into the surface of the substrate.

Machine on ground provided with heat resistant wall used for isolating

An automatic information receiving terminal device in a character/graphic information network system including a videotex communication network or a public communication network (telephone network) is connected to an information center through the videotex or public communication network so that various items of image information from the information center can be received by the terminal device. The terminal device having an internal clock and a time setting unit. The terminal device can automatically receive or reproduce desired information at an each time preset by the time setting means, so that the terminal device can automatically be operated without manual intervention so as to give emergency information or the like timely to a number of people.

Videotext communication network with a receiving terminal that

A wear-resistant metal member comprises a surface that has a sprayed layer consisting essentially of, by weight, 2 to 10% C, 18 to 60% Cr, 0.3 to 20% V, 25% or less Mo, 25% or less W, 10% or less Nb, 10% or less Ti, 10% or less Zr, 10% or less Hf and the balance being Fe in a proportion of 20% or greater. The sprayed layer has a martensite-phase matrix containing carbide particles, nitride particles or carbonitride particles. In addition, the member of the present invention is produced by the steps of: plasma-spraying the above-described metal in a reduced pressure atmosphere; and quenching the thus-sprayed metal layer from a predetermined temperature to form a materisite phase in that layer. In addition, the sprayed metal layer may be subjected to carburizing, nitriding or carbonitriding to form a carburized, nitrided or carbonitrided layer in the sprayed metal layer. The member of the present invention has a high wear resistance and is used as a sliding portion of a valve gear in an internal combustion engine.
