Title: Ferromagnetic metallic powder for magnetic record medium, and magnetic record medium
Inventor: OTA EIJI
IPC: G11B5/73
Filed: 1992-01-31
Abstract: PURPOSE:To pick out only the metallic powder excellent in dispersion property efficiently by making the difference between the surface potential at pH10 of metallic magnetic powder and the surface potential at pH7 an index. CONSTITUTION:In respect of the dispersion property of each metallic magnetic powder, the difference between the surface potential ZP10 at pH10 and the surface potential ZP7 at pH7 is determined as an index, and an object where the difference of surface potential is 30mV or more, that is, an object which fulfills the condition that ZP10-ZP7<=-30mV is selected as one which has favorable dispersion property, and it is used as magnetic powder for a magnetic record medium. That is, in the metallic magnetic powder, the dispersion property and the surface potential difference ZP10-ZP7 show nearly accurate proportional relation. Accordingly, the surface potential difference ZP1-ZP7 becomes the accurate index of dispersion property. Since such surface potential difference ZP10-ZP7 is made an index in selection when selecting metallic magnetic powder which has favorable dispersion property, it follows that only the metallic magnetic powder which has favorable dispersion property is selected, and the metallic magnetic powder which has favorable dispersion property is used efficiently.

IPC: F16J15/16
Filed: 1990-02-21
Abstract: PURPOSE: To facilitate removal of a seal ring by introducing such a structure that its cylindrical sealing surface elongates beyond at least one of the clamps toward the cylindrical surface to be sealed. CONSTITUTION: When clamps 10 and 14 are moved by screw 42 along the axis as approaching each other, abutting clamp surfaces 20 and 30 opposing in the axial direction cause undulate walls 22 and 28 of a seal ring 12 to simultaneously contact in the axial direction in the adjoining position spaced similarly in the axial direction from the axis of assembly. The contacting position extends into a substantially continued contact line around the axial direction opposing surface between the seal ring 12 and clamps 10 and 14. Fastening of the clamps 10 and 14 around the seal ring 12 is made by increasing the diameter of the seal ring 12 through its deformation with respect to the flat surfaces of the clamp surfaces 20 and 30 and the gap between the two walls 27 and 32 is sealed.  When the fastening force is released, the ring 12 restitutes partially to the initial shape and can simply be removed upon deformation of the diameter again.
