A thermal spray material includes a mixture of 5-30 weight % of an AlSi alloy powder with 95-70 weight percent of a cast iron powder to provide abrasion resistance for aluminum alloy parts. The AlSi alloy powder contains 12-30 weight % Si, at least one element selected from a group consisting of 0.5-5.0 weight % Cu and 0.2-3.0 weight % Mg, 1-15% of at least one element selected from the group consisting of Fe, Mn, and Ni, and a mass balance of Al. The cast iron powder contains 2-4 weight % C, no more than 0.3 weight % Si, and 0.5-3.0 weight % P. A sliding surface of a sliding member is thermal sprayed with a coating of this thermal spray material to provide a sliding member having excellent abrasion resistance.

The present invention provides a method for blasting an inside surface of a cylinder, in which a steady rough surface is always obtained efficiently in the whole region of inside surface of cylinder for an internal combustion engine. For this purpose, a blast gun 1, which is provided so as to be moved vertically by a traverser 11 and capable of rotating around the axis thereof, has a blast nozzle 3 for blowing blast particles 2 in the vicinity of the lower end thereof. The blowing direction of the blast nozzle 3 is slant downward. A cylinder block 4 is placed upright so that the axis of each cylinder is vertical with a cylinder head mating surface 4e on the upper side, and is isolated from the surrounding space by a cabinet 12. The blast gun 1 blows the blast particles 2 while lowering in each cylinder of the cylinder block 4, by which the inside surface 5 of cylinder is blasted. A blast particle recovering reservoir 13 is provided under the apparatus to recover the blast particles 2.

A method of producing an optical fiber preform includes preparing a glass preform that has a hole extending in a longitudinal direction formed on one end of the glass preform in such a manner that a length of the hole is equal to or less than half of an entire length of the glass preform, synthesizing a porous glass preform by depositing glass particles on an outer circumference of the glass preform having the hole formed on the end, and sintering the porous glass preform after arranging the porous glass preform in such a manner that the end having the hole formed thereon points downward and the hole is open to the air.
摘要:
In a wide area Ethernet network, an edge side gateway (EGW) acquires layer 2 tunneling control information from an authentication server when a PADI is received from a user terminal, stores the correspondence between the source address of the PADI and the layer 2 tunneling control information in its management table, encapsulates the PADI in accordance with the layer 2 tunneling control information, and transmits the encapsulated PADI packet to the wide area Ethernet network. A core side gateway (CGW) having received the encapsulated PADI packet stores the correspondence between the tunneling control information and the source address extracted from the received packet in its management table, and forwards the PADI obtained by decapsulating the received packet to a broadband access server. Thereafter, each of the EGW and CGW forward received packets for the user after converting their format by referencing to the management tables.

摘要:
An object of the present invention is to provide a single-phase film of a metal sulfide with good quality, and a method for preparing a metal sulfide film at a low cost in a convenient manner. The present invention provides a preparation method of a metal sulfide film, comprising the steps of providing metal halide, such as iron halide (FeCl3, FeI3, FeBr3, FeCl2, FeI2 and FeBr2), as a first raw material and a thioamide compound, such as thioacetamide, as a second raw material, preferably vaporizing these raw materials and reacting them at atmospheric pressure; and a metal sulfide film prepared by this method.
