摘要： A control circuit (20) of a mass flow control device (1) retains the relation (Cd=f(ReTH)) between the Reynolds number and the actual discharge coefficient of a sonic nozzle (13) in the area where the Reynolds number is small. In such an area, the sonic nozzle can be used as a variable mass flow element for controlling mass flow rate. If a pressure Pu and a temperature Tu of an upstream fluid of the sonic nozzle 13 are detected, the theoretical mass flow rate QmTH and the theoretical Reynolds number ReTH can be calculated; since the actual discharge coefficient Cd can be calculated by the above relationship Cd=f(ReTH) based on the calculated Reynolds number, the actual mass flow rate Qm can be calculated based on the relation of Qm=Cd.multidot.QmTH. In the control circuit 20, in order to obtain the predetermined mass flow rate Qm, the upstream fluid pressure Pu and temperature Tu of the sonic nozzle are obtained based on the above relationship, and a variable valve (12) is driven so that the mass flow rate may have this value. Since the properties of the sonic nozzle can be made full use of, it is possible to control trace amounts of mass flow rate with extremely high accuracy.

摘要： A trip throttle valve with a manual exerciser and combination of a hydraulic piston and a biasing force bearing sleeve is provided in place of a piston. The piston is not directly connected to a valve stem and the sleeve is threadably engaged with the valve stem so as to cause relative axial movement between the sleeve and the valve stem when the stem is rotated through the manual exerciser. The hydraulic portion of the valve is provided with a by-pass passage so that the piston is made axially movable toward the sleeve under the pressure which occurs when the by-pass passage for the hydraulic liquid is blocked but the piston is arrested at a certain axial position where the by-pass passage is still blocked and the axial movement of the sleeve is restricted against the piston. Blocking of the by-pass passage is arranged to take place after the axial separating distance between the sleeve and the piston reaches a predetermined value so that any inadvertent movement of the valve stem by the engagement of the piston with the sleeve is avoided.

摘要： A high-strength die-quenched part 1 is formed by heating a high-strength steel sheet 11 up to an austenite region, hot stamping and cooling inside a mold, and its microstructure has the martensite wherein carbide particles 2 are finely dispersed over an entire region including prior-austenite grain boundaries. It is desirable that the prior-austenite grain size in the microstructure of the high-strength steel sheet, which is a base material, be 10 μm or smaller. The high-strength die-quenched part has high-strength and high-ductility thanks to its martensite.
