    摘要: A ceramic coating bonded to an iron tubular member comprising a bonding layer formed on a surface of the iron tubular member by a reaction of an iron tubular oxide layer of the iron tubular member and a silicate; and an iron oxide diffusion-preventing layer produced from fine metal oxide particles or an organometallic binder by firing on a surface of the bonding layer. The ceramic coating may further comprises an oxidation-preventing layer, a heat-insulating layer, a refractory layer or a thin dense protective layer. It may be produced by coating the surface of the iron tubular member with a silicate binder to form a layer which is then converted to a bonding layer by a heat treatment in a steam atmosphere; coating the surface of the bonding layer with fine metal oxide particles or an organometallic binder to form an iron oxide diffusion-preventing layer; and after curing and drying firing the resulting ceramic coating in an atmosphere having an oxygen partial pressure of 10 mmHg or less.

    摘要: A method of manufacturing a heat resistant member includes the step of designing the shape of the heat resistant member, including the substeps of estimating thermal stress of the heat resistant member by heating a model formed by a high-thermal expansion material which has a similar shape to the desired shape of the heat resistant member while the model is restrained and also while it is free. The high-thermal expansion material is different from the material of the member being modeled and has a thermal expansion coefficient greater than that of the material of the member being modeled. Additionally, the step of designing includes the substeps of measuring the strain of the model at each of a plurality of predetermined positions while the model is heated by strain gauges adhered to predetermined positions on the model, and calculating the stress at each predetermined position from the difference in measured strain values between the restraint state and the free state. Finally, the manufacturing method includes casting the heat resistant member to the designed shape.

    摘要: A method of producing a nodular graphite cast iron having high strength and toughness in shorter time and with reduced production cost. The method comprises the following steps: rapidly cooling the casting, which has been removed from the mold at a predetermined temperature above the A.sub.1 transformation point, at such a cooling rate as not to permit the generation of pearlite structure, after having been held for a predetermined time within the austenite temperature range or immediately after having been removed from the mold; once stopping the rapid cooling at a temperature above the Ms point; slowly cooling the casting within a temperature range above the Ms point for a predetermined time or holding the casting at a constant temperature within a predetermined temperature range above the Ms point for a predetermined time; and cooling the casting slowly down to the normal temperature.

    摘要: A method of and apparatus for fusion bonding a continuous synthetic thermoplastic resin fastener strip having a fastener profile portion and a base portion opposite the profile, to a continuous film substrate. The substrate is advanced continuously through a bonding zone. Continuous direct transit of the fastener strip is effected from thermoplastic extruder downwardly through a short distance to the bonding zone, so that in the short transit distance the fastener strip will retain substantial residual thermoplastic fusion temperature. The fastener profile portion is chilled while the strip is in transit to the bonding zone, solidified and stabilized, but the base portion is left at sufficient residual fusion temperature to remain thermoplastic to the bonding zone where assembly of the strip and substrate is effected by fusion bonding of the base portion to the substrate. An annular rotary heating surface may be applied to a narrow locally limited longitudinal area of the substrate for supplying to such area fusion promoting heat in the bonding zone, such area being aligned with the fastener strip in the assembly. The longitudinal area may be stretched by the rotary heating surface.

    摘要: A model for measuring stress distribution constituted by a light, integral polyurethane foam having little unevenness in density, the polyurethane foam being at predetermined sites provided with undercoating layers, to each of which a resistance wire strain gauge is attached via an adhesive, each of the undercoating layers having a thickness of 50-300 .mu.m and being made of a material which is unreactive with, hardly penetrable into and softer than the polyurethane foam. The stress distribution measurement is conducted by supporting the polyurethane foam model by one or more support members at positions corresponding to the restraint sites of an actual metal member, and applying a load to the polyurethane foam model at a position corresponding to the site of the actual metal member to which a load is actually applied, thereby measuring a stress distribution in the polyurethane foam model under substantially the same restraint conditions as in the actual metal members.
