Inventor: YAMADA SHINICHI
IPC: F16K31/02
Filed: 1987-10-07
Abstract: PURPOSE:To obtain a flow regulator constructed so that the interior of a conduit and the exterior thereof are structurally interrupted not to cause leakage of a fluid by regulating flow using superconductive material in the conduit and magnetism generating means outside the conduit. CONSTITUTION:In the interior of a conduit 11 having an inlet port (g) and an outlet port (h), there are provided a plurality of spheres 13 formed by superconductive material and a shielding plate 14 having holes with a diameter less than the minimum diameter of the above spheres 13 for preventing the spheres 13 from flowing out the conduit 11 through the above inlet port (g) or the outlet port (h). There is provided magnetism generating means 12 such as a coil or the like for generating magnetic flus outside the conduit 11. In this arrangement, when magnetic field is not applied from the outside of the conduit 11, the above spheres 13 are pressed in the holes of the shielding plate 14 by a fluid in the conduit 11 to interrupt the fluid. When magnetic field is applied, the spheres 13 are dislocated from the holes of the shielding plate 14 against the flow by Meissner effect to open a passage.

Title: Load detection mechanism
Inventor: TANAKA HIROSHI
IPC: G01G3/12
Filed: 1984-11-30
Abstract: PURPOSE:To enable accurate measurement of a load, by providing force escaping parts between a point near the load cell fixed end and a point near the beam fixed end. CONSTITUTION:A vertical groove is provided on linking members 15 and 16 at both ends of a beam 11 to form force escaping parts 30 and 31 while vertical grooves are provided on both sides of linking members 19 and 20 of a strain gauge body 21 of a load cell 12 to form force escaping parts 32 and 33. As these force escaping parts 30-33 are formed on both sides of the members 15, 16, 19 and 20, they are easy to deform by lateral force Fy and Fx working on the beam 11 and the load cell 12 but hard to deform by a vertical force, namely, shearing force. Therefore, even when a load is applied on a support member 25 and displaces the beam 11 and the load cell 12 to put forces Fy and Fx on the beam 11 and the load cell 12, the forces Fy and Fx are absorbed through the force escaping parts 30-33 until the forces Fy and Fx are almost down to zero to have no effect on the output of the load cell 12. Thus, accurate measurement of a load can be done.
