Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To manufacture a large bore of seat at a low cost, in which fluid leakage hardly occurs. SOLUTION: In a high-temperature rotary valve, the outer periphery 6A of an elastic seat 6 which is mounted in a gap between each of both end openings 1a, 1b of a valve box 1 and a valve disc 2 is locked to the valve box 1 and the inner periphery 6B of the elastic seat 6 is put in contact with the valve disc 2.

Title: Apparatus for avoiding bird-attack, etc.
Inventor: FUKUTOMI SHINYA
IPC: A01M29/32
Filed: 1994-11-30
Abstract: PURPOSE: To avoid a short circuit, service interruption, etc., caused by birds by a method wherein annular rotary units and cylindrical rotary units which are attached to a wire or an arm metal are properly combined and arranged and make birds which come flying and perch unstable and unsettled. CONSTITUTION: After a wire is installed, an annular rotary unit 1 which is composed of half-ring sections is attached to a wire at a predetermined position so as to be able to rotate by mating coupling protrusions 2 and coupling recesses 3 with each other to couple the left side and the right side with each other. Then a cylindrical rotary unit 4 which has a slit 3 partially in a longitudinal direction is attached to the wire by opening the slit 3 so as to touch the annular rotary unit 1 and to be able to rotate. Therefore, if a bird comes flying and perches on the protrusion 5, etc., of the rotary unit 4, the annular rotary unit 1 and the cylindrical rotary unit 4 rotate and the perching bird loses its balance and can not be settled.  With this constitution, short-circuit failures between the wires caused by birds and short-circuit failures caused by bird nests on the arm metals can be avoided.

Thus, the whole of the body 1 becomes freely flexible toward the non-back contact side. Regarding a motion toward an opposite direction, mutually coupled plates 30 and 40 receive the teeth 31 and 41 to form an approximately integral structure.  The motion of the body 1 is, therefore, restricted and the flexibility thereof toward the back contact side is restricted.
