Title: Double-sided mirror finished sapphire substrate and its manufacturing method
Inventor: HATTORI OSAMU
IPC: B24B37/08
Filed: 2000-01-24
Abstract: PROBLEM TO BE SOLVED: To manufacture a double-sided mirror finished substrate hardly warping by using a double-sided polishing machine for an entire sapphire polishing process unlike single-sided polishing of an adhesion system, and to reduce injuries on the surface of the substrate by adopting a polishing method using no diamond polishing. SOLUTION: Since a double-sided lapping machine and a double-sided polishing machine are used for an entire polishing process and a workpiece is processed while absorbing a warp produced by an internal stress change caused by reduction of the thickness of the workpiece, by processing it with its raw material made freely movable in a carrier, a finished product does not have a big warp. The workpiece is gradually brought close to a mirror finished surface by multi-stage polishing by using abrasive having different particle diameters. Thereby, a process producing little surface injury and using no expensive diamond abrasive material can be materialized.

Title: Spraying material for greening slope surface
Inventor: KAJIKURI TATSUYA
IPC: E02D17/20
Filed: 2000-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a spraying material for greening a slope surface capable of using a dehydrated cake containing aluminum as a soil basic material. SOLUTION: The dehydrated cake obtained by charging a flocculant formed of an aluminum compound into drainage, and then flocculating, settling, and dehydrating insoluble matters containing concrete or cement particles in the drainage is mixed with SG soil, to thereby obtain the soil basic material. Then, activated chicken manure, slow release fertilizer, a soil activator, a bonding agent, and seeds are mixed with the soil basic material, to thereby obtain the spraying material. The thus obtained spraying material is mixed with a suitable amount of water, and then sprayed on a lath-stretched slope surface. Although the spraying material contains aluminum mixed therewith, which functions to inhibit plants from growing, the activated chicken manure restrains the action of aluminum to inhibit plant growth, and therefore the plants smoothly grow.  As a result, by using the spraying material, the dehydrated cake containing aluminum can be effectively used as one component element of the soil basic material of the spraying material.
