Title: Method for forming refractive index distribution in optical glass
Inventor: WAKABAYASHI SATOSHI
IPC: C03C21/00
Filed: 1985-04-26
Abstract: PURPOSE:To apply a refractive distribution in an optical glass eliminating the influence of bubbles generated in molten salt, by holding a substrate glass directing the mask upward opposite to the direction of gravitational force and contacting the exposed part of the substrate glass with molten salt to effect the ion exchange with the salt. CONSTITUTION:A glass substrate 3 on a supporting table 5 is held in the molten salt 2 in a manner to direct the masked (4) face of the substrate 3 toward the liquid face 6 of the molten salt, i.e. opposite to the direction of gravitational force. The bubbles generated between the mask 4 or exposed part 4A and the liquid surface 6 are allowed to float toward the liquid surface 6 by buoyancy. Accordingly, there is no residence of bubbles at the exposed part 4A, the diffusion of dopant can be performed uniformly over the whole surface of the exposed part 4A, and the strain unnecessary to the refractive index distribution of the lens can be eliminated. The unmasked surfaces of the substrate 3 are also brought into contact with the molten salt 2 to cause the formation of a refractive index distribution unnecessary for a hand micro-lens in the substrate 3 near the surface, however, the refractive index distribution can be removed easily by cutting, grinding, polishing, etc. of the substrate 3.

IPC: G11B11/105
Filed: 1988-04-14
Abstract: PURPOSE:To increase reproduction power and to improve recording stability by using an amorphous magnetic material of Ho-Fe-Co for a reading out layer consisting of exchange-bonded two-layer films. CONSTITUTION:The reading out layer is constituted substantially of the amorphous magnetic material consisting of Ho, Fe and Co. Recording sensitivity increases if the Curie temp. of the recording layer is lowered in case of the exchange-bonded two-layer films. The Curie temp. of the recording layer is preferably about >=100 deg.C in terms of the stability of recording information. On the other hand, the max. reproduction power increases and the reading out characteristic improves if Hox-(Fe1-y-Coy)1-x contg. Ho of a ferrimagnetic material is used as the reading out layer, but the Curie temp. higher than the Curie temp. of the recording layer is required in order to use the same as the reading out layer and, therefore, (y) is preferably 0.05 to 0.20, i.e., the ratio between the Fe and the Co is preferably about 95:5 to 80:20. The large max. reproduction power is thereby obtd. and the recording stability is improved.
