Title: Aspheric surface processing machine
Inventor: MASAKI TAKESHI
IPC: B24B13/00
Filed: 1986-09-30
Abstract: PURPOSE:To seek to form high accurate shape by positioning an aspheric shape of a work and a tool relatively by means of a horizontal, vertical and rotational positioning mechanism and always squaring the tool axis with the normal line direction of the desired shape of the aspherical shape with a tool constant pressure rocking mechanism. CONSTITUTION:The tip of a tool 9 is squared with the rotation center of a rotation axis 18 and the aspheric shape of a work 2 is traced by the positioning of X and Y axes by means of a horizontal direction positioning mechanism 3 and a vertical direction positioning mechanism 13. Concurrently with it, the tool 9 is rotated theta degree by a rotational positioning mechanism 12 so that is may accord with the normal line direction at the X, Z points of aspheric shape of the work 2, thus the positioning is executed. This value (X, Z, theta) is the desired value for aspheric shape. And the tool 9 is pushed, with the desired pressure, against the work 2 by an adjusting mechanism 11 and rocked by a tool constant pressure rocking mechanism 10 so that the axis of the tool 9 always may accord with the normal line direction of the desired shape.

Abstract: PURPOSE:To form a stable flame, reduce nitrogen oxides, and reduce noises by forming the upper section of a burner head with a double structure and providing a large through-hole outside of the burner head and a minute through- hole in the burner head on the same axis to form a minute flame hole. CONSTITUTION:A burner head 3 that is mounted on the open brim 1a of a vaporization cylinder 1 has a structure in its upper section, and a large through- hole 4a is formed in the burner head outside 3a and a minute through-hole 4b in the burner head inside 3b respectively. Those respective through-holes 4a and 4b are provided on the same axis and opposed to each other so that a minute flame hole 4 is formed in the upper section and a flame hole 4' that is a little larger than the flame hole 4 is formed in the lower section. This minute flame hole 4 is a flame of a small scale so that its flame temperature is low and the generation of nitrogen oxides are suppressed. On the other hand the larger flame hole 4' becomes a stable flame, and holds the flame of the minute flame hole 4, and there is no lift combustion and the stability of combustion is excellent.

Twist caused by the false twister 10 of two crossed belts is propagated to the upper stream so that the stable rovings are wound round the filaments. In the operation, the yarns 3 and 3' are nipped and released by the cut roller 9 having a notch on the peripheral surface, so that length of the twisting zone is changed and alternate twist of S and Z twist are formed. In the operation, nip and release are opposed between both the yarns 3 and 3' to inverse the twist direction. When the yarns 3 and 3' are incorporated by the collecting guide 11, one stable core yarn 4 of self twisting is obtained.

Title: Production of magnetic record medium
Inventor: ISHIKAWA AKIRA
IPC: G11B5/82
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To permit stable running of a head and to enhance S-N ratio in high density recording by forming an underlayer comprising Cr, Mo, W, Nb, Ta or an alloy based on these in a specified thickness between a nonmagnetic disk substrate and a magnetic layer. SOLUTION: An underlayer comprising Cr, Mo, W, Nb, Ta or an alloy based on these is formed in 5-500 nm thickness on a substrate and crystals are grown under orientation so that the (100) or (110) crystal lattice faces of the underlayer are made parallel to the substrate to enhance magnetic anisotropy in the running direction of a head. A magnetic layer preferably comprises Co, Fe, Ni or an alloy based on these and it is preferable that crystals are grown under orientation so that the (110) crystal lattice faces of the magnetic layer are made almost parallel to the substrate because magnetic anisotropy is enhanced by the growth. When a layer of a carbide such as WC or (W-Mo)C is used as a protective layer, sliding and corrosion resistances can be enhanced.
