Title: Cumulative chemical and physical phenomenon detector
Inventor: SAWADA KAZUAKI
IPC: H01L29/78
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a cumulative chemical and physical phenomenon detector whose sensitivity can be increased by a method wherein a voltage output from a sensing region is input through a thin oxide film as a change in the potential of a semiconductor surface and the change in the potential is converted into an electric charge. SOLUTION: A sensing part has a structure to which an ion signal is input. Generally, instead of a metal electrode of a MOS structure, a silicon nitride film (an Si3N4 film) 23 is deposited on a silicon oxide film (an SiO2 film) 22, and its surface acts as an ion-sensitive part. A reference electrode 26 is inserted into an aqueous solution 24, and the potential of the aqueous solution 24 is kept constant. A pulse voltage is applied to an electric-charge supply part, a barrier part and a reset gate part, and a DC voltage is applied to an electrode in a part other than another floating diffusion part. The electric-charge supply part, the floating diffusion part and a reset drain part are formed of a diffusion layer, and other parts are formed to be of the MOS structure.

Title: Method and device for filtering by precoat membrane
Inventor: KABASAWA KATSUMI
IPC: B01D61/20
Filed: 2000-10-18
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for filtering by a precoat membrane, by which the operation cost is reduced. SOLUTION: Raw water is filtered by passing through a filtration membrane module 5, on which the precoat membrane PC is formed by sticking flocculated floc produced by the addition of a flocculating agent in the raw water filtered through aggregation precipitation and sand filtration or activated carbon filtration on the filtration membrane module 5. Because fine turbid substance or fine organism, which causes the clogging of the filtration membrane, is collected by the precoat, the clogging hardly occurs. The clogged precoat is stripped and removed from the filtration membrane by back washing and then, the throughput is easily recovered. Because the flocculated floc used as a filter aid is produced by using the flocculating agent originally used in the aggregation precipitation, special labor and cost are unnecessary and the operation cost is reduced.

Title: Grinding method
Inventor: TAKAGAKI SHIGEKI
IPC: B02C19/06
Filed: 2000-10-19
Abstract: PROBLEM TO BE SOLVED: To enhance the grinding efficiency of an air current grinder. SOLUTION: A classifier 3 is installed in the internal classification zone of a grinding tank 2 and a grinding zone is used as a grinding chamber 7. A jet air current is generated in the grinding chamber 7 by injecting compressed air into the grinding chamber 7 from a compressor 10 through a jet nozzle 8, and as a result, the particles of a material to be processed loaded in the grinding chamber 7 are subjected to mutual collision, clashing from behind and grinding among themselves under the effect of the jet air current. Further, the resisting force of the air current lessens by setting the interior of the grinding chamber 7 at a negative pressure or increasing the temperature of the grinding chamber 7 and thus the probability that the particles of the material to be processed may enter into the jet air current is high.  Consequently, the grinding efficiency is enhanced and the grinding capacity is increased.
