摘要： PURPOSE:To enable the bonding of a ceramic part and a metallic part in a short time at a low cost by forming a stress-relaxation layer consisting of a soft metal on the inner surface of a concave fitting part of the metallic part using three specific steps. CONSTITUTION:The subject method for bonding a ceramic part and a metallic part consists of a process to form a stress-relaxation layer of a soft metal on the inner surface of a concave fitting part of the metallic part, a process to insert a protruded insertion part of the ceramic part into the concave fitting part of the metallic part and a process to bond the protruded insertion part of the ceramic part to the concave fitting part of the metallic part. In the above processes, the stress-relaxation layer is formed by the following three steps. The 1st step comprises the deposition of a soft metal on the inner surface of the concave fitting part of the metallic part to form a padding. The 2nd step comprises the cutting of the surface of the padding by machining to form a machined inner surface. The 3rd step comprises the plating of a soft metal to the machined inner surface to form a plated part.

摘要： PURPOSE:To shorten a corrugated tube forming time. CONSTITUTION:A blank tube 5 is chucked at two points, the intermediate part between them is locally heated, the corrugate tube is formed by repeating that the backward side chuck 1 is moved larger than the forward side chuck 3, and two chucks 1, 3 are moved to the same direction at the same time. Because pressing and feeding the blank tube 5 are simultaneously executed, its forming time can be shortened. The corrugated tube forming device is composed of two chucks 1, 3, a heating, cooling means 4 to heat its intermediate part blank tube and to cool after bulge forming, and a guide arranged between the backward side chuck 1 and the heating means 4.

摘要： PROBLEM TO BE SOLVED: To provide a diamond like carbon (DLC) film which has a lower coefficient of friction, higher adhesiveness and abrasion resistance than a DLC film formed with a conventional technology; a method for producing the film with an improved film-forming speed and in a shortened cycle time; a sliding member having a protective film with the low coefficient of friction, the superior abrasion resistance and the superior adhesiveness; and the manufacturing method therefor.
SOLUTION: The method for producing the diamond like carbon (DLC) film on a substrate includes dissociating a hydrocarbon in an atmosphere containing an introduced hydrocarbon and inert gas while sputtering only a metallic target, instead of using a solid carbon target. Thus formed film is a metal-diamond-like-carbon (DLC) composite film having an atomic ratio of carbon/metallic element of 5 to 50.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a simpler and more inexpensive gear than the prior art.
SOLUTION: This manufacturing method comprises a constraining process of coaxially engaging a cylindrical original gear 21 having teeth in the inner surface with a constraint fixture 11 having an inner surface 111 of which clearance G of the inner surface facing to the cylindrical outer surface of the original gear 21 is axially different, and a deforming process of pressing the outer surface 211 of the original gear 21 onto the inner surface 111 of the constraint fixture 11 by heating and thermally expanding the original gear 21 and plastically deforming the original gear 21 so that the outer surface 211 of the original gear 21 has a shape corresponding to the shape of the inner surface 111 of the constraint fixture 11. In other words, the outer surface 211 of the original gear 21 is pressed onto the constraint fixture 11 by the thermal expansion in thermally treating the original gear 21, and the original gear 21 plastically deforms in response to different size of the clearance G between the constraint fixture 11 and the original gear 21.

摘要： PROBLEM TO BE SOLVED: To efficiently obtain a desired heating regardless of the shape of a material to be heated without necessarily needing a specified heating coil by arranging a core for collecting alternating magnetic field so as to be controllable to the position in the heating coil, in which the alternating magnetic field is generated by supplying high frequency current. SOLUTION: In a high frequency induction heating apparatus for executing the heat treatment of hardening, solution treatment, etc., by heating the material 110 to be heated, such as metal-made member, the alternating magnetic field is generated by supplying the high frequency current from a high frequency current source into the heating coil 121 and this alternating magnetic field is collected with T-shaped cores 131, 132 and impressed to the heating surface of the material 110 to be heated to induction-heat the surface. Further, these cores 131, 132 are controlled to the relative position to the heating coil 121 with a core position control means 100 composed of an actuator of a cylinder, etc., and a control part, etc., connected with this actuator with an air supplying passage, etc. In this way, the distance(d) between the cores 131, 132 and the step parts A, B, respectively, is held to the constant to uniformly heat the material 110 to be heated.

摘要： PURPOSE:To obtain the required bending curve by always restricting the projecting part of corrugated pipe to the vertical direction against the bending surface of pipe and the center axis of pipe and relatively making so that the un- deformed projecting part of corrugated pipe is made to be easily bent. CONSTITUTION:Because the projecting part of pipe of the pipe 16 to be bent is always restricted with a pipe projecting part restricting means 18, the deforming of sectional shape due to the flatness of pipe 16 during processing the pipe 16 can be almost prevented. Therefore, at the projecting part of pipe 16 being deformed with bending, the reduction of the geometrical moment of inertia is almost eliminated, the side of the increase of machining hardening with the plastic deformation is become larger than the increase of the property to be easily bent with the reduction of the geometrical moment of inertial. So, at the projecting part of deformed corrugate pipe 16, the bending toughness is become larger corresponding to the increase of deformed amount. That is to say, the property to be easily bent of un-deformed projecting part of corrugate pipe 16 is increased.
