Title: Hot rolling method for difficultly workable material
Inventor: HAMURA NOBUYOSHI
IPC: B21B3/02
Filed: 1986-04-30
Abstract: PURPOSE:To prevent the generation of a surface flaws and to improve workability by stopping the supply of cooling water to rolling rolls, rolling a difficultly workable material under a prescribed rate of the rolling reduction exerted thereto, then rolling the material while supplying the cooling water to the rolls. CONSTITUTION:The supply of the cooling water to the rolling rolls is temporarily stopped and the difficultly workable material is rolled down at 1.01-2.00 rolling reduction ratio at the time of initial rolling. The temp. drop of the material surface is thereby decreased and the rolling of the material in a high temp. region where the surface flaws are not generated is executed. The surface structure of the material is, therefore, made into the rolled structure having good hot workability and the generation of the surface flaws in the subsequent rolling is suppressed. The rolling is executed while the cooling water is supplied to the rolls in the subsequent rolling and therefore, the roll surface temp. does not increase up to the dangerous temp. at which cracks are generated by thermal deterioration. Since the rolls are cooled, the deterioration of the rolls is prevented.

Title: Both side type floppy disk device
Inventor: YONEDA FUKUO
IPC: G11B17/32
Filed: 1989-04-20
Abstract: PURPOSE:To enable the stable contact between a disk and a head even in case of a plane wobble by providing a projecting part consisting of a groove along a reversely tapered groove and a rail-like flat part to the outer side of a flat part on a magnetic core side of a magnetic head. CONSTITUTION:The projecting parts having the grooves 11a and 11b and the rail-like flat surfaces 12a and 12b are provided on the outer sides of the magnetic cores 9a and 9b of upper and lower sliders 4a and 4b. Since positive pressure is generated on the flat surfaces 12a and 12b by rotating a disk 1, the disk 1 is bent in the opposite direction to the surfaces 12a and 12b respectively, so that the magnetic cores 9a and 9b come into contact stronger than ever with the disk 1. The disk 1 is prevented from flawing due to extremely bending around at corners of flat surfaces 5a and 5b opposite to this with positive pressure of the surfaces 12a and 12b by the grooves 11a and 11b. By this method, the plane wobble caused by a disk waviness is suppressed to substantially eliminate the wobble in the vicinity of the magnetic cores, thus obtaining the stable contact.
