Title: Nb 3 sn superconductive wire and manufacture thereof
Inventor: MIYATAKE TAKAYUKI
IPC: C22C27/02
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To efficiently manufacture an unit weight of some tens to hundreds kg level having its stable critical current characteristics by forming an Nb3 Sn superconductive wire in which a coated copper is integrated by metal bonding of an outside copper and of an inside copper. SOLUTION: A coated portion of an Nb3 Sn superconductive wire having its copper rate of 1 to 10, for example, is formed of good metal bonding between a copper portion (inside copper) of the Nb3 Sn superconductive wire with the low copper rate being a core material and a copper portion (outside copper) of a copper pipe into which this core material is to be inserted. Thus, the outside copper and the inside copper are integrated by metal bonding, and whereby the Nb3 Sn superconductive wire with stable critical current characteristics and a greater single weight is obtained.  Next, to manufacture a Nb3 Sn superconductive wire with high copper rate, the Nb3 Sn superconductive wire compound wire material in which the area rate of a copper portion is 0.2 to 1, for example, against a non-copper portion is extended by inserting the material into a copper pipe having its smoother inner surface than an outer surface of this compound core material. Thus, a single quantity of some tens to hundred kg level having its stable critical current characteristics is effectively manufactured.

IPC: B03C3/88
Filed: 1978-12-22
Abstract: PURPOSE: To discharge dust from apparatus whose internal pressure is high by incorporating a dust delivery mechanism reasonably into a high-pressure air-tight mechanism.  
     CONSTITUTION: The cylindrical pressure-resistant case 2 having the chute 9 hole on its upper part is provided at the lower part of the casing 1 of an electric dust collector with a pressure-resistant structure and then connected with the side plate 3 with the reinforcing rib 8 to keep it air-tight. The dust collected in the casing 1 is dropped onto the conveyer case 7 inside the pressure-resistant case 2 through the chute 9 and then delivered to the discharge port 17 below the case by the endless main chain 18, where the expansion of the chain can be regulated inside a completely air-tight type pressure-resistant case by allowing the rotary shaft of chain conveyer to move to the conveyer tail 11 portion inside the pressure-resistant case 2. Thus, completely air-tightened pressure-resistant conveyer can be realized comparatively easily and therefore the discharge of dust under high pressure is made possible.

The pressure loss in the water feed part is thus decreased and the driving power is correspondingly decreased. The cooling in the stable state against the fluctuation of load is made possible in the water discharge part.
