Abstract: The present invention is a press forging method by which porosities in a raw material are removed and mechanical properties such as ductility and toughness of a steel product are at a required level in a case that a steel ingot is treated as a raw material in press forging. A cylindrical steel ingot (a so-called “round billet”) is set onto a die as a raw material, and, a forging process is applied to the steel ingot so that buckling of the steel is not generated during the forging process and that a reduction ratio and a forging ratio are more than predetermined values, respectively.

Abstract: [Object]To provide a manufacturing method of an optical filter having favorable film quality by removing a foreign substance adhered onto a surface of a substrate by cleaning before a thin film is formed. [Solution] By performing a cleaning step P1 for cleaning a substrate S by means of a solution including water, a pre-treatment step P3 for plasma-treating a surface of the substrate S cleaned in the cleaning step P1 by plasma of an oxygen gas, and a thin film formation step (P4, P5) for forming the thin film on the surface of the substrate S plasma-treated in the pre-treatment step P3, the foreign substance adhered onto the surface of the substrate can be effectively removed. In the pre-treatment step P3, only the oxygen gas is introduced to an area where the plasma is generated, and a flow rate of the oxygen gas to be introduced is greater than a flow rate of the oxygen gas introduced in the thin film formation step.

Abstract: Disclosed is an apparatus for generating a water electrolytic gas, wherein an electrolyte inlet is formed in the bottom of an electrolytic cell for generation of a water electrolytic gas, and an outlet is formed in the top thereof for the extraction of a mixture of an electrolyte and a generated gas. In the electrolytic cell, an anode and a cathode are provided, and an alkali electrolyte spinning and passing portion are arranged between these electrodes. With this arrangement, water electrolysis is performed, and a mixture of the electrolyte and a water electrolytic gas is extracted from the upper end of the electrolytic cell and transferred to a water electrolytic gas/electrolyte separation cell. A gas-liquid separation process extracts only the water electrolytic gas to the exterior, while the electrolyte is returned to the electrolytic cell by an electrolyte circulation device, to continue the performance of the electrolytic reaction.
