Abstract: The present invention provides a method for producing active hepatocyte growth factor activator (HGFA) and active hepatocyte growth factor (HGF) without using animal serum. The present invention relates to a method for producing active HGFA without using animal serum. The method is characterized in that it comprises a step of obtaining a culture supernatant comprising pro-HGFA by culturing mammalian cells expressing inactive hepatocyte growth factor activator (pro-HGFA) in a medium without serum, and a step of adjusting the culture supernatant comprising pro-HGFA obtained in the above step to weakly acidic to convert pro-HGFA into active HGFA. The present invention also relates to a method for producing active HGF with HGFA produced by said method.

Abstract: An electromagnetic valve is configured with an electromagnetic section, a flow path section, and a sealing member between them. This separate arrangement improves a degree of freedom for arranging inflow and/or outflow passage. This separate arrangement also enables to reduce a size of the electromagnetic section. A plunger comes in contact with a central portion of a spherical portion of a valve member. A normally open compression spring comes in contact with a peripheral portion of the valve member. The valve member can be reliably seated on the normally close valve seat even if the plunger is slightly tilted.

Abstract: A valve body has an inflow passage for a working fluid, an outflow passage for the working fluid, and a pressure relief passage, which connects the inflow passage and the outflow passage by bypassing a normally close valve seat. A pressure relief valve is located in the pressure relief passage. The pressure relief valve closes the pressure relief passage, if a pressure of the working fluid in the outflow passage is lower than, is equal to, and is higher by a pressure difference less than a predetermined relief pressure than a pressure of the working fluid in the inflow passage. The pressure relief valve opens the pressure relief passage, if the pressure of the working fluid in the outflow passage is higher by a pressure difference equal to or higher than the relief pressure than a pressure of the working fluid in the inflow passage.
