摘要： PURPOSE:To improve abrasion resistance, corrosion resistance and acid resistance by forming a film of a high m.p. compd. on a substrate surface by a chemical vapor deposition treatment then cooling the same forcibly from the temp. at which a hardening effect appears. CONSTITUTION:A film of carbide or nitride of metals selected among Si, B, group 4a, 5a, 6a metals of periodic law table, or oxide of Al, Cr is formed on the surface of a substrate 21 in a vessel 31 by a chemical vapor deposition treatment. After the formation, a treating jig 20 placed thereon with the substrate 21 is detached from a desorbing part 15 for electrode and is moved by a moving device 34 into a cooling chamber 32 which is held evacuated at the same pressure as that in the vessel 31. A sluice valve 33 is closed, and a cooling gas is introduced from a gas producer 30 through an introducing part 35 for cooling gas into the chamber 32 and the substrate 21 is cooled forcibly with a fan 36. Thus the hardening of the substrate 21 is completed.

摘要： PURPOSE:To raise the fitting accuracy an U-shaped tube inserted into fins and a coupling tube as well as enhance the reliability of soldered portion by a method in which the flared and expanded portion of the tube is constrainingly formed by the inside diameter portion of an end place hole. CONSTITUTION:A large number of cooling fins 3 with slits are laminated, and an U-shaped tube 5 is provided through upper and lower end plates in the inside of the fins 3. To form an highly accurate expanded portion in the pipe, a pipe- expanding punch 8 with a ball is intruded into the U-shaped tube 5 through its end portion and a queen 3 is fixed to the tube 5. When the ball expands to the endmost portion of the pipe, a flared pipe-expanding punch 9 goes down to perform the expanding work of flared pipe. Thus, a flared and expanded portion of the pipe is formed.

摘要： PURPOSE:To enhance the thermal efficiency of a heat generation type gas producing unit by placing the unit at the temp. rising section of the heating zone of a nonoxidation heat treatment furnace so that it can be heat exchanged for a means of conveying a substance to be treated. CONSTITUTION:Heat generation type unit 4 for producing a gas used in a heat treatment furnace is placed at the temp. rising section of heating zone 11 of the furnace, and combustion chamber 56 packed with gas conversion catalyst 55 is heat insulated with heat shielding plate 57. When heat treatment operation is carried out in the furnace, a gas mixed with combustion air is fed to chamber 56 through piping 53, burned with burner 54, and acceleratedly converted with catalyst 55. This hot converted gas radiates its heat in radiation tube 581, etc. to heat substance 72 to be treated. The gas leaving tube 581 is cooled and dehydrated with heat exchanger 41 and further cooled and dehydrated with refrigerator 22. The resulting gas is then fed to heating zone 11 and cooling zones 121, 122, where it is used as a gas for nonoxidation treatment.

摘要： PURPOSE:To bond surely and securely a fine wire by pressing and fitting the fine wire into the fine-wire fitting part provided to a material to be joined and irradiating an energy beam like a spot to both members. CONSTITUTION:A square groove 2 is provided to a terminal 1 and the fine wire 3 is pressed and fitted into the groove 2 by means of a press-fitting jig, etc. The wire 3 is so positioned that the end thereof do not jump out of the groove 2. The laser beam B is irradiated like a spot to both members in this state. The spot center of the beam B is made coincident with the center of the wire 3 to prevent the molten state from deviating from the axis of the wire 3. The beam B joins instantaneously the wire 3 and the terminal 1 and therefore the joining in the atm. is made possible. Since the end of the terminal 1 and the boundary between the molten part and unmolten part is spaced by >=0.5 times the diameter of the wire 3, the wire 3 is surely and securely joined and the automatic joining operation is made possible.
