SOLUTION: When a container 1 is turned upside down and turned again to an ordinary posture, the content B is once accumulated in an intermediate pool 20 and then discharged to a measuring chamber 12 and the stagnant content in the measuring chamber 12 is shaked out and further the content B to be shaked out at the next manipulation is accumulated in the intermediate pool 20. In this time, four stages of shaking-out volume can be optionally selected by rotating a shutter with the container 1 normally erected and closing optional unit measuring chambers out of four chambers 12a. Accordingly, when the content B is shaked out with some of measuring chambers closed, since the next content B is replenished in the unit measuring chamber 12a by turning the container 1 upside down, only adjusted content can be promptly shaked out.

Abstract: PURPOSE:To join securely different metals which are impossible to be joined directly to each other in the stage of joining the different metals with which direct joining by welding is impossible by interposing a specifically composed insert piece for joining between both metals and welding said metals. CONSTITUTION:Direct melt-joining of different metallic plates such as a lightweight Al plate and a highly corrosion resistant Ti plate to each other is impossible because an intermetallic compd. by both metals is formed to deteriorate the strength and corrosion resistance in the joint part.
