Abstract: PURPOSE:To perform switching operation merely by pressing one valve at one time, by constituting it in such a way that the wall of each valve ball store section can push out a valve ball from water outlet when a bar member is rotated and each valve ball remains stopping the water outlet except when it is necessary. CONSTITUTION:A bar member 7 is mounted rotatively on a casing 1, and water outlets 4a-4c are mounted on the casting 1. When the bar member 7 is rotated, valve balls 11a-11c are pressed up respectively against walls 13a-13c of valve ball store section, but when valve ball store recessed sections 10a-10c face the water outlets 4a-4c respectively, the valve spheres 11a-11c stop the water outlets 4a-4c. As the valve ball store recessed sections 10a-10c are directed in diferent directons, the valve balls 11a-11c are pushed out from the water outlets 4a-4c. On the other hand, the value balls 11a-11c remains stopping the water outlets 4a-4c except when it is necessary. Consequently, one valve ball only need to be pushed up at one time at the time of change-over.

Title: Thin magnetic film
Inventor: ISHIWATA NOBUYUKI
IPC: H01F10/14
Filed: 1989-12-29
Abstract: PURPOSE:To restrain the decline in magnetic permeability by a method wherein the fine crystal particles of a magnetic body thin film comprising multiple alloy fine crystal particles using iron as a base metal are oriented in the specific direction to the film surface while a specific compound is separated on the fine crystal particle field. CONSTITUTION:A thin magnetic film 12 is composed of multiple alloy fine crystal particles in body-centered cubic lattice structure using iron as a base metal. The surfaces of respective fine crystal particles are oriented in parallel with the surface of the film 12. Accordingly, the (100) axial direction is random but in parallel with the film 12. Furthermore, a carbide or a nitride as the alloy constituent is separated on the crystal particle field. Since the crystal particles are oriented meeting said requirements, the crystal magnetic anisotropical energy on the film surface is lowered to ensure the high magnetic permeability for diminishing the coercive force. At this time, it is recommended that the mean diameter of the crystal particles does not exceed 100Angstrom . Through these procedures, said carbide or nitride can be separated on the crystal particle field so that the carbide or nitride may disturb the growth of fine crystal particles of the magnetic body thin film during the thermal process for manufacturing this film into a magnetic head so as to avoid the decline in magnetic permeability as well as the increase in coercive force.
