Title: Magneto-optical disk
Inventor: SHIMAZAKI KATSUSUKE
IPC: G11B11/10
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of tracking errors and to stably maintain rotation by specifying a dimensional relation between the maximum distance, from the center of the spindle, of the face in which a hub for the magnetic clamp ('the hub') being supported by a substrate transmits the rotary force of the spindle to the substrate, and the diameter of the substrate. SOLUTION: The hub 3 made of a material attractable to a magnet 4 is attached to a substrate 1 in a state separated from it. The material of the hub 3 is a metallic magnetic substance or the like such as Fe, Ni, Co or alloys containing these. The hub 3 is attracted to the magnet 4 fixed on a spindle 2. This attracting force is transmitted to the substrate 1, which is attracted to the disk supporting part of the spindle 2. In this case, a relation of B/A>=0.125 exists between the diameter A of the substrate 1 and the maximum distance B, from the center of the spindle 2, of the face in which the hub 3 transmits the rotary force of the spindle 2 to the substrate 1.

Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To micronize the opening of a screen and to provide a strong filter medium by combining several kinds of mesh screens having a different mesh opening, with respect to a metallic filter medium used in a filter. SOLUTION: A plurality of metallic mesh screens 2, 3 and 4 are successively placed on a supporting plate 1 having many slit through-holes 1a each having a wedge-shaped section, and the opening of the respective screens 2, 3 and 4 is made smaller than that of the one below. The coarse-mesh screen 2 is laid on the supporting plate 1, the medium-mesh screen 3 is laid thereon as the intermediate layer, and the fine-mesh screen 4 is laid thereon as a surface layer to constitute a filter medium to be used. Consequently, microfiltration is realized, and the strength of the medium is also increased. Since the screen mesh opening of the metallic screen is made gradually larger downward, the filtrate passed through the medium of the surface layer is excellently discharged.  Further, as the filter medium is metallic, the medium is easily cleaned, and the medium reinforced by the lamination is never deformed.
