Title: Abrasive sheet and its manufacture
Inventor: YAMAMOTO MOTOTANE
IPC: B24D11/00
Filed: 1985-07-31
Abstract: PURPOSE:To remove abrasion dust from an abrasive surface thereby sharply increase abrasion efficiency by forming a number of slots almost uniformly on the abrasive film of an abrasive sheet. CONSTITUTION:Resin adhesive material in which abrasive material is dispersed is applied, on one side surface of plastic sheet 1, solidified thereafter, thus abrasive film 2 is formed. This process yields ordinary plane-abrasive-sheet. The plane of the abrasive film 2 on this abrasive sheet is scratched with a heated-up comb made of metal, resulting in formation of a number of slots almost uniformly distributed on the abrasive film 2, thus obtaining a predetermined abrasive sheet B. By using the abrasive sheet B for abrading a material to be abraded, generated abrasion dust is removed from the abrasive surface by falling into these slots 3, moreover, since abrasion-surface pressure is high, and no local temperature increase occurs, abrasion efficiency can be sharply increased.

Title: Optical recording medium
Inventor: MATSUTAME CHIKANOBU
IPC: G11B7/24035
Filed: 1990-06-27
Abstract: PURPOSE:To improve availability of laser light energy, recording sensitivity, recording and reproducing stability, and reliability by allowing a recording material and self-convergent non-linear optical material to coexist in a recording layer. CONSTITUTION:A recording layer 1 containing a recording material and self- convergent nonlinear optical material is formed on a substrate. The self- convergent nonlinear optical material incorporated into the recording layer 1 with the recording material is such a material that shows nonlinear increase in the refractive index with increase in temp. and/or intensity of laser light 2. The laser light 2 for writing entering the recording layer 1 is absorbed by the layer 1 to give local temp. increase. The refractive index of the self- convergent nonlinear optical material in the layer 1 changes according to the temp. increase and/or light-induced polarization, and the refractive index in the center area of the convergent point 3 changes most. Therefore, the incident light is further converged to increase the light intensity and temp. of the center area of the convergent point 3. Thus, availability of laser light energy, recording sensitivity, recording and reproducing stability, and reliability of the medium can be improved.
