Title: Mounting material for grinding
Inventor: SHIOZAWA HAJIME
IPC: B24B37/04
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To provide excellent hold force of a workpiece to be ground and enable the use of a mounting material for grinding in precision grinding without template by giving water repellency to a sheet which has a surface skin layer consisting of a close multi-porous structure and has a continuous multi-porous structure made of polyurethane resin. SOLUTION: A coating made of polyurethane resin and other component is applied on a film and is washed by water after polyurethane resin is coagulated to obtain a sheet which has a surface skin layer having a close multi-porous structure and a continuous multi-porous structure made of urethane resin. After the sheet having the multi-porous structure made of urethane resin is attached on a film by using adhesive, it is water repellent-treated by using water repellent agent containing 1% or more of fluorine water repellent agent at the weight ratio. If this sheet is used as a mounting material, aqueous solution (slurry) containing abrasive particles which are used in grinding does not penetrate in and adhere and remain on the mounting material.  Consequently, the slurry does not enter between a workpiece to be ground and the mounting material, and a wafer to be ground adheres on the mounting material because adhesive force is not reduced by the slurry so that the wafer does not slide and move.

Title: Vegetation net
Inventor: ICHIKAWA TSUKASA
IPC: C08L101/16
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To decompose a vegetation net satisfactorily so as not to remain after plants are reared on the face of slope by composing the vegetation net of biodegradable resin. SOLUTION: A vegetation net 10 is formed of biodegradable aliphatic polyester resin fiber such as polylactic acid resin fiber, and fertilizer band through- holes 11 are formed at specified spaces in the vegetation net 10. At the time of construction, the vegetation net 10 is spread on the face of slope by a stretching rope 12, and fertilizer bands are alternately passed through the fertilizer band through-holes 11 and moored. Plant seeds are further sprayed onto the surface of the vegetation net 10. The vegetation net 10 is therefore decomposed gradually in natural environment after plants are reared on the face of slope, so that natural environment is prevented from getting worse.

IPC: G01M3/16
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a detecting system for leakage occurrence position capable of accurately detecting leakage occurrence position in a short time in a management type wastewater treatment plant. SOLUTION: Sets of wire electrodes A1 to A5, B1 to B5 of upstream and downstream of a water shielding film 10 are sequentially selected, and the current flowing between the electrodes of each set is phase detected by the same phase as or 90-degree different phase from the two-phase AC power source 15 by first and second phase detectors 16, 17. A squaring circuit 18 receives the output of the detector 16, outputs the square value. A divider 19 divides the output from the circuit 18 as a numerator by the output from the detector 17 as a denominator. As a result, in the case of the combination of the electrode near the leakage occurrence position due to the damage of the film 10, the output of the divider 19 is raised from the value between the other electrodes, thereby detecting the leakage occurrence position.
