Title: Motion sensor
Inventor: TAKAMA TERUHIRO
IPC: G01C9/10
Filed: 1998-11-14
Abstract: PROBLEM TO BE SOLVED: To provide a motion sensor which can detect vibration with simple constitution and has excellent durability. SOLUTION: A motion sensor 1 is equipped with a ball 40 whose surface has conductivity, a substrate 10 formed in a disk type, a positive electrode surface 28 and a negative electrode surface 38 which are alternately arranged on the same plane, maintaining a gap on the substrate 10, mount the ball 40 on the upper side, and move the ball 40 freely from one to the other across the gap G, and a cover 50 preventing the ball 40 from flying outward. When vibrating is generated, the ball 40 rolls and slides on the surface connecting the positive electrode surface 28 with the negative electrode surface 38. When the ball 40 reaches a part just above the gap G, the electrode surfaces 28 and 38 make electric continuity. When the ball 40 comes off from the gap G, the electrodes surfaces 28 and 38 are electrically separated from each other.  Thereby an intermittent signal as a detection signal of vibration generation can be outputted from an output terminal to the outside.

Abstract: PURPOSE:T heighten follow-up performance to the contraction of an inner tank by providing plural vertical fibers fastened to an anchor metal member with the lower end embedded in floor slab concrete, and cold insulating powder material filled between the fibers. CONSTITUTION:Inner tank roof lifting force is transmitted to an outer tank floor slab concrete 4B via an inner tank side plate 2, a skirt, fibers 9 and an anchor metal member 8. Cold insulating powder is filled around the fibers 9 piercing pits piercingly provided at equal spaces at the inner tank floor slab concrete 4A. The inner tank side plate 2 and the inner tank bottom plate 3 are connected to each other by an annular corner curved plate so as to form a space for fitting the fibers 9 while avoiding the stress concentration of an inner tank. Plural fibers 9 are extended vertically at equal spaces through the pits, and the skirt is coaxially set to the floor slab concrete 4A so that the centerline of a lower end flange coincides with the centerline of the pit. Penetrting heat is thereby reduced, and follow-up performance to the contraction of the inner tank can be heightened.
