Title: Waste melting furnace and its tapping part
Inventor: SUGIYAMA NOBUYUKI
IPC: F23G5/00
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To make it hard to occur that a tapping hole is blocked, abrased or damaged even when operating condition is changed by a method wherein a mechanism, capable of changing the opening degree of a molten slag flowing passage, is provided in the tapping part of a water melting furnace. SOLUTION: A tapping unit, for example, is constituted by providing an opening degree regulating valve 5 for changing the opening degree of a flow passage at the tip end of a trough for guiding molten slag 7, discharged out of a melting passage 1. The opening degree regulating valve 5 is structured so that the valve 5 can be rotated about the rotating shaft 6 of the same provided at one end of the same while the opening degree of a trough 4 in the flow passage of the molten slag 7 can be regulated by the rotation of the opening degree regulating valve 5.  When the opening degree regulating valve 5 is rotated about the rotating shaft 6 of the same valve to regulate the opening degree of the trough 4 in such a constitution, blocking of a tapping hole 2 by the solidifying and accumulating of the molten slag 7 in the tapping hole 2 or the abrasion and damage of the tapping port 3 by the flow of exhaust gas can be prevented whereby a melting furnace can be operated stably.

Title: Floating type solid intermediary body for centrifugal sedimentation separation
Inventor: OGATA HAJIME
IPC: G01N33/48
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To accurately perform the removal of erythrocytes from blood and the operation for separating nuclear cells from blood without requiring any special skill by providing a separation vessel with the solid intermediary body existing in an aim specific gravity zone at the time of subjecting at least two kinds of particles each kind of which has different specific gravity from the other kind, to centrifugal separation. SOLUTION: At the time of removing erythrocyte from blood, a hole or groove 2 is made in the bottom surface of a bowl-like solid body which has elasticity and a little lower specific gravity than that of the erythrocyte, by perforating the bottom through it to form the objective solid intermediary body 1 (elastic body). Then, an aliquot part of blood is injected into a vessel consisting of a centrifuge tube fitted at its bottom with the elastic body 1 and thereafter, the vessel is rotated to generate a centrifugal force. At this time, the initially settled erythrocytes reach the bottom of the centrifuge tube through the hole 2.  When the product of (the specific gravity difference between the erythrocytes and the elastic body 1)×(the centrifugal force) becomes larger than the force required for mobilizing the elastic body 1, the elastic body 1 is pushed up by this specific gravity difference and moves to a position determined by the shape of the elastic body 1 and the specific gravity difference between the erythrocytes and the blood plasma to collect the objective nuclear cells in the bowl-like part of the elastic body 1 and to divide them from the other blood components.
