Title: Shape changeable film or stringlike article thereof
Inventor: UEDA ATSUSHI
IPC: A61F5/44
Filed: 1994-07-21
Abstract: PURPOSE:To use a film consisting of two layers different in permanent strain as a substitute of a rubber band, a string knot or a bundling tape by making the film possible to pull and return in its longitudinal direction. CONSTITUTION:For example, a two-layered film consists of a non-elastomer layer 1 (high in permanent strain) composed of polyethylene and an elastomer layer 2 (low in permanent strain) composed of an elastomer. When this film is pulled in its longitudinal direction (MD direction), the polyethylene layer 1 has permanent strain in the MD direction and becomes short in its lateral direction (TD direction). Since the elastomer layer 2 is ready to return to the original shape, the film is curled in such a state that the polyethylene layer 1 becomes inside to become a string like shape. In this case, when the stress ready to return to the original of the elastomer layer 2 becomes larger than the bending modulus of the polyethylene layer 1, a curl is generated. The obtained string like article becomes a rubbery state having stretchability.

Title: Magnetic head slider and magnetic disk device
Inventor: CHIBA AKIO
IPC: G11B21/21
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To decrease the wear amt. and to obtain high reliability by leaving carbon having good sliding property in a matrix and adding carbon having good cutting property. SOLUTION: When a sintered body essentially comprising TiO2 and containing preferably 0.5-20vol% Nb2 O5 and preferably 5-20vol% graphite is used as a magnetic head slider, coagulation wear due to frictional heat can be prevented. When the amt. of Nb2 O5 added is small, the preventing effect against oxidation sintering of carbon can not be obtd. When the add, amt. is large, grains are largely coarsened and chipping during processing is increased. By increasing the acid-amt. of graphite, the frictional coefft. is decreased but scratches are produced in a disk, which decreases sliding property. More preferably, by using a sintered body with addition of Ti by 2-10vol% to form a reaction layer of <=5μm thickness with Ti around graphite, higher reliability can be obtd.
