Filed: 1986-08-20
Abstract: PURPOSE:To aim at enhancing spontaneous action, cutting durability and cutting safety of a cutting grind stone for fragile materials, by containing and dispersing short fibers having a high strength in hardenable resin holding therein abrasive grain. CONSTITUTION:A cutting grind stone 9 is formed by abrasive grain 5 which is made of diamond, CBN or the like and which is bonded by thermohardenable resin binder 6 in which a harness adjusting agent which is micro powder of high strength metal, semiconductor materials or dielectric materials, and a reinforcement 7 for reinforcing a mechanical strength are contained and dispersed. As the above-mentioned reinforcing agent 7, there are use carbon fibers such as SiC group fibers, PNA graphite fibers, pitch graphite fiber or the like, or short fibers such as Al2O3 fibers, Si3N4 fibers or boron fibers, having a length less than 20 time as large as the thickness of the grind stone, or whiskers. Thus, a suitable hardness and strength may be obtained to have a high cutting ability with less breakage of the grind stone itself. Further, it is possible to obtain spontaneous action due to the fibers having a high strength and the flexible resin.

IPC: G11B11/10
Filed: 1990-07-26
Abstract: PURPOSE:To enlarge an allowable range for the film thickness of a magneto-optical recording medium film by forming a dielectric film as a first layer, magneto-optical recording medium film which thickness is less than 500Angstrom  while containing the 6-12atom% of oxygen as a second layer, dielectric film as a third layer and metal film as a fourth layer on a transparent substrate. CONSTITUTION:On the transparent substrate, the dielectric film is formed as the first layer, the magneto-optical recording medium film, which thickness is less than 500Angstrom , is provided as the second layer while containing the 6-12atom% of oxygen, the dielectric film is formed as the third layer and the metal film is formed as the fourth layer for this magneto-optical disk. The magneto-optical recording medium film as the second layer contains the 6-12atom% of oxygen. This oxygen decreases the absorption coefficient of the magneto-optical recording medium film and reflected linearly polarized light is hardly made elliptical. When the amount of this oxygen is less than the 6atom%, the operation of oxygen is made weak and on the other hand, when the amount exceeds the 12atom%, the coercive force of the magneto-optical recording medium film is decreased. Then, long-term weather resistance is lowered. Thus, the allowable range is enlarged for the film thickness of the magneto-optical recording medium film, and the magneto-optical disk can be produced with high yield and obtained with a high performance exponent.
