    摘要： A composite follow valve for internal combustion engines such as an intake and an exhaust valve and the method for producing the same are disclosed. The valve is produced by integrating into the whole a valve head portion molded from a lightweight, heat-resistant material selected from a group of titanium alloys and titanium-aluminium alloys, a stem portion molded from a high-strength alloy steel, made hollow inside to reduce weight, and a stem end portion molded from a hard material selected from a group of martensitic stainless steel, silicon nitride and silicon carbide ceramics. Since the different materials of the separate valve components are selected to meet the requirements of their particular functions and operating condition under which they are placed. Also, because of this separate arrangement, the valve can be produced at a relatively reduced cost, since the use of expensive materials is saved. Furthermore, the valve is molded, not in a whole body, but in separate components, there is no use for expensive isothermal forging machines as in the case of prior art production methods.

    摘要： A semiconductor substrate with a groove is placed in a plasma generating reaction chamber. Silicon, oxygen and hydrogen containing gases are introduced into the reaction chamber as process gases. A ratio of a gas flow of the hydrogen containing gas except the silicon containing gas to a total gas flow of the silicon containing gas and the oxygen containing gas defines a first gas-flow ratio. A ratio of a gas flow of the oxygen containing gas to that of the silicon containing gas defines a second gas-flow ratio. The first and second gas-flow ratios establish a linear function for a critical condition. A cluster formation condition is set up by relatively increasing the first gas-flow ratio while relatively decreasing the second gas-flow ratio with respect to the critical condition. A cluster suppression condition is also set up by relatively decreasing the first gas-flow ratio while relatively increasing the second gas-flow ratio with respect to the critical condition. The process gases are supplied to the reaction chamber under the cluster formation condition and under the cluster suppression condition, alternately, to form an insulating film buried in the groove.

    摘要： A plural number of types of material powders are accommodated in an accommodation chamber in a mixed state and the material powders are continuously subjected to a self-exothermic reaction inducing chemical reactions between the material powders caused by heat of reaction released when the mixed material powders synthesize. The synthesized material of high temperature due to the self-exothermic reaction is pressed by utilizing an electromagnetic force just after the finish of the self-exothermic reaction. The exothermic reaction is caused by an ignition circuit including an ignition electrode and the electromagnetic force is generated by an electromagnetic force generation circuit including an electric current inducing means. These circuits are connected through and regulated by a relay circuit. Thus the synthetic products of fine structure are obtained.
