Abstract: PURPOSE:To enhance accuracy in the measurement of a micro flow rate by disposing a narrow channel, a movable valve operable integrally with a diaphragm, a pressure preventive board for limiting fluctuation of pressure acting on the diaphragm, and a pressure fluctuation eliminating member on the upstream side from a fluid oscillation element. CONSTITUTION:Gas is introduced at pressure of P1 through an inlet 13 and fed through a pressure fluctuation eliminating member 13. The flow rate is then measured at pressure of P2 by means of a fluid oscillation element 14 and fed at pressure of P3 through an outlet 15. It is introduced through a pressure introduction pipe 25 to one side of a diaphragm 22 provided, on the other side thereof, with a pressure preventive board 27 for limiting fluctuation in the pressure P1 on the inlet side. When the flow rate of gas is low, the gas pressures P1, P2 and P3 are substantially equal to each other and a movable valve 23 is set gravitationally on a valve seat 24. Consequently, the gas passes through the narrow channel 21 and reaches the inlet of the oscillation element 14. Since the quantity of gas ejecting through the narrow channel 21 scarcely vary even upon fluctuation of the inlet pressure P1, a highly accurate and stabilized measurement is realized.

Filed: 1978-10-02
Abstract: PURPOSE: To increasing the deposition strength of a juncture surface part by decreasing the amount of deposited chromium carbide by carrying out a solidifying heat treatment by rapid water cooling successively after a feed of a finishing current in a low-current region following a welding current.  
     CONSTITUTION: In an upset butt welding process, a direct welding current of a constant value is fed from plus electrode 1 to minus electrode 2. After a fixed period of time, the welding current is sloped down and in succession, a deposition finishing current of a constant value is fed as long as or longer than the feed time of the welding current, thereby finishing an upset. Immediately after the feed of the finishing current, cooling water is jetted out from pipe 4 upon welded part (b), which is rapidly cooled. Through this solidifying heat treatment, chromium carbide deposited in welding is solidified again inside of chain member A. Therefore, products can be obtained which have juncture surface parts with excellent tensile resistance and bending resistance.
