Title: Valve gear and fluid control valve system therewith
Inventor: MOROZUMI EIICHI
IPC: F16K31/02
Filed: 1990-04-10
Abstract: PURPOSE:To miniaturize a valve drive body with a spring interposed as well as to reduce watt consumption by installing both ends of the valve drive body consisting of a linear shape memory alloy, in a valve box, having a valve element engaged with the valve box and making it so as to contact or separate to or from a valve seat. CONSTITUTION:A valve seat 11 is installed in a tubular valve box 10, setting up a valve element 14 there. A valve drive body 12 consisting of a single linear shape memory alloy is installed in this valve box 10 via an insulator 13. A valve rod 15 is attached to the valve element 14, spreading a pring 16 there. When an energized current of the valve drive body 12 is controlled by a detecting signal of a flow sensor 17, the valve drive body 12 varies its form by dint of Joule heat, thereby controlling an on-off rate of the valve element 14. For example, when the energized current is increased, the valve drive body 12 extends, making the valve element 15 come into contact with the valve seat 11. Consequently, even if there is deviation in a component of the valve drive body 12, it operates the valve element positively, thus miniaturization in the valve drive body is made possible and, what is more, watt consumption becomes lessened.

Abstract: PURPOSE:To position a passbook with high accuracy by a method wherein the passbook is positioned by a pressing force of passbook pressing means and taper-form feed rollers toward reference members, and the reference members corresponding to respective stop positions at this time are disposed oppositely to each other. CONSTITUTION:A pair of guide plates 17 and 18 are disposed on the sides of a feed path 12 oppositely to each other.

Title: Slag cutting method used for converter or the like
Inventor: FUJII KOUICHIROU
IPC: C21C5/46
Filed: 1980-07-10
Abstract: PURPOSE:To surely prevent slag inclusion into molten steel flow by keeping electrically conducted between a nozzle stopper and the shell of a converter, and detecting the change from the molten steel flow to slag flow as a change in electric current. CONSTITUTION:When the depth of the molten steel in a converter A attains a constant value, a conductive refractive stopper 5 is inserted into th converter A, thereby closing the furnace inner side of a tap hole 11. After a prescribed time, the stopper is moved upward by a preset rate to create a prescribed clearance, thence tapping is resumed. In the initial period of this tapping, the stopper 5 and a shell 4 are held conducted by molten steel 2, and an ammeter 10 provided to the 2nd conductor 7 swings largely. As the contact matter at the leading end of the stopper 5 changes to slag 1, the swing of the ammeter 10 decreases because the electric resistance of the slag 1 is large. From this change in electric current, the molten steel 2 and the slag 1 are discriminated. The stopper 5 is again lowered quickly to decrease or close the outflow clearance of the molten steel.
