Title: Target for forming magneto-optical disk protective film
Inventor: NAITO KAZUNORI
IPC: G11B11/105
Filed: 1989-02-07
Abstract: PURPOSE:To put a target with less variations in its composition and having a long service life to practical use and to improve the quality of a magneto- optical disk by hot-pressing a mixture of rare-earth metal grains and dielectric grains, and using the obtained sintered body to form the target. CONSTITUTION:The powder of Tb as a rare-earth metal and the powder of SiO2 as the dielectric material are mixed in a specified weight ratio, and sufficiently dispersed in each other by a ball mill. The mixture is hot-pressed under appropriate conditions, and then worked into desired shape and size to form a target. Consequently, since an abnormal discharge which was easy to generated between a rare-earth metal chip and the dielectric material is prevented, a uniform protective film is formed, and the quality of a magneto-optical disk is improved.

IPC: C22C21/02
Filed: 1987-02-13
Abstract: PURPOSE:To manufacture an Al-Si alloy casting free from pinholes and excellent in mechanical properties, by adding rare earth having strong affinity for hydrogen to a molten Al-Si alloy containing Sr so that specific amounts of rare earth metal remain. CONSTITUTION:The Al-Si alloy casting excellent in mechanical properties is cast by adding incorporating 0.001-0.30wt.% Sr to an Al-Si alloy so as to refine eutectic Si and increase elongation characteristics. At this time, the Al-Si alloy casting frequently develops a defect of many pinholes since Sr hydrolyzes the moisture in the air to generate H2 gas. In order to prevent the above defect, a master alloy consisting of Al and rare earth metal is added and incorporated to the Sr-added molten Al-Si alloy by the amount to the extent where the rare earth remains by 0.010-0.045wt.% in the Al-Si alloy. In this way, the rare earth metal absorbs H2 gas formed by hydrolysis and reduces H2 gas, so that occurrence of pinholes due to H2 gas to the Al-Si alloy casting can be prevented.
