Filed: 1981-05-21
Abstract: PURPOSE:To decrease the number of the parts of a display valve and to simplify its assembling by forming a flap valve of flexible synthetic resin in one body in  an overcurrent display device which has fluid stored in a display cylinder. CONSTITUTION:When an overcurrent flows through an electric wire l, a power shaft is rotated by 45 degrees against the elastic force of a return spring S incorporated in a rotary solenoid RS to rotate an operating lever 64 by 180 degrees. When the rotary solenoid RS having finished rotating starts return rotation by the return spring S, the operating finished rotating starts return rotation  by the return spring Sm the operating lever 64 rotates a rotary disk 61 to move  a stringlike member 42 up against the gravity of the valve body 43 of a display  device 1 and the viscous resistance of fluids 40 and 41. At this time, the valve  body 43 while flexing downward is rotated and the whole body moves into the  colored fluid 40. After the operation, the valve body 43 stays at the upper part  of the colored fluid 40 to perform overcurrent display. Consequently, a flap  valve is formed of synthetic resin in one body and the number of parts is decreased.

Title: Method for adding easily vaporizing alloy into rh degassing vessel
Inventor: ASAHINA TAKESHI
IPC: C21C7/04
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To add an easily vaporizing alloy in good yield and to effectly float up and separate produced inclusion under sufficient stirring by forming the easily vaporizing alloy as wire-state and supplying this alloy into molten steel through a top-blown lance. SOLUTION: The easily vaporizing wire 6, such as CaSi, is introduced into a circulating chamber 4 of an RH gas vessel from the upper end part of the top-blown lance 5 while passing in the top-blown lance 5 through a seal part 7. At this time, supplying speed of the wire 6 is desirable to be >=40 m/min. This lower limit speed is calculated from melting speed of the wire 6 in the molten steel and in the case of being less than this speed, this alloy is vaporized before promoting the melting in the steel and the remarkably lowering of the yield is brought about. Further, since the charging of the alloy wire 6 to the center part in the vessel, i.e., the central part of the molten steel fluid by using the top-blown lance 5 as the introducing tube, can be executed, the stirring of Ca can efficiently be executed.

When the potential at the pint T is higher than that at the point G, the potential at a point T is shigher than that at the point G, the potential at the U goes to the 'H' level, and the potential at the point G is reduced by the voltage drop of R3. The potential at the point U is inverted by an inverter N2, and that at the point Y is inverted by an inverter N3, and a synthesized waveform of waveforms at points Y and U is outputted to a point V, and the inverted pulse at the point V is outputted to an output W.
