Patent number: 8222182Abstract: A manufacturing method is provided for producing a carbon material adsorbing nitrate nitrogen, nitrate nitrogen or a fluoride ion through an ion exchange with a chloride ion. Plant material can be impregnated with a calcium chloride solution. Subsequently, the plant material can be carbonized to enable the plant material to support chloride ions that can provide ion exchanging capability with nitrite nitrogen, nitrate nitrogen, and a fluoride ion via calcium. The temperature of the carbonization permits the deposits of a calcium chloride compound within 2% to 25% by weight as a functional group in a carbonized material having ash components.Type: GrantFiled: October 24, 2007Date of Patent: July 17, 2012Assignee: Nisshoku CorporationInventors: Satsohi Hayashi, Riei Yokoyama

Patent number: 5421123Abstract: The laying of a vegetation mat in close contact with a clad surface is achieved. The vegetation mat has a net, which prevents freezing or flow-away of vegetation material without the need for stretching a separate net. The mat comprises a layer of vegetation material selected from the group consisting of soil improvement material, fertilizer, organic material, vegetation seeds and combinations thereof, a front and back sheet, which are capable of being at least partly decomposed and are coupled together to wrap the vegetation material. A net having a mesh size permitting the budding and growth of the vegetation seeds, is provided on the front surface of the front sheet.Type: GrantFiled: December 29, 1993Date of Patent: June 6, 1995Assignee: Nisshoku CorporationInventors: Michihei Sakate, Tomofumi Matsumoto, Jungi Katayama, Nobumasa Mitunaga, Shunta Tada, Kaname Hori, Hiroyuki Kambe, Kiwamu Iizuka

Patent number: 5245785Abstract: A mat with seed is produced by adhering turf seeds onto a nonwoven fabric. Water-soluble adhesives are prevented from being absorbed by the nonwoven fabric to ensure uniform turf surfaces of good appearance. The water-soluble nonwoven fabric is superior in dispersibility, and comprises long fibers having a reduced width and bound with a binder comprising a water-soluble resin and a very small quantity of water repellent reagent such that the long fibers are intertwined in one direction only by foams of water-soluble starch material having a diameter of 7 mm or less.Type: GrantFiled: July 5, 1991Date of Patent: September 21, 1993Assignee: Nisshoku CorporationInventors: Mituo Taniguchi, Yasuhoshi Fuzishima, Motonari Hanamaki, Masashi Shibata

Patent number: 5002427Abstract: A hydrophobic material used in the construction of a culver for improving the drainage of the culvert. The hydrophobic material comprises a textile or knit fabric, preferably biodegradable, having large and small mesh portions. A soil-aggregating agent is adhered to the small mesh portions of the textile or knit fabric. The hydrophobic material can be coated with a water soluble film to prevent the soil-aggregating agent from being removed during construction or handling.The hydrophobic material used for the drainage of a culvert is capable of keeping the water-penetrating property of the culvert for a long time.Type: GrantFiled: August 9, 1989Date of Patent: March 26, 1991Assignee: Nisshoku CorporationInventors: Hiroyuki Kambe, Masashi Shibata, Masaichi Sugimoto
