Title: Improved treatment of bottom sediment
Inventor: KATAOKA KATSUYUKI
IPC: C02F11/06
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To oxidize anaerobic materials of bottom sediment to reform the bottom sediment and to restrain the elution of its nutrient salts to unnecessitate treatments such as land reclamation treatment of the bottom sediment and dehydration of the dredged bottom sediment by bringing granular gel which is obtained by shutting up a nitrate ion containing water solution in a polymerized silicate gel into contact with the bottom sediment of lakes and marshes or the sea. SOLUTION: After a water glass water solution 2 is added to a nitrate ion containing water solution 1 and pH adjustment is made by nitric acid so that the pH value becomes in an almost neutral area, the mixture is conveyed in a gelling reaction pipe 4 at low flow rate for a prescribed time by a mono pump 3, and silica as monomer is quickly polymerized to form a three-dimensional structural body, causing the whole liquid to gel in the pipeline 4. The obtained gel is subjected to grain refining by a gel crusher 5 to prepare fine grain gel 6. When the fine grain gel 6 is quickly precipitated to water bottom to disperse it onto an anaerobic bottom deposit bed, nitrate ions gradually ooze out from in the fine grain gel 6. In this way, anaerobic material is oxidized by oxidizing action of the nitrate ions and oxygen in the nitrate ions to change the bottom deposit into aerobic conditions.

Title: Ceramic substrate for resin-sealing semiconductor chip
Inventor: NAKANO KATSUHIRO
IPC: H01L23/28
Filed: 1988-01-29
Abstract: PURPOSE:To alleviate the difference of large thermal expansion coefficients between sealing resin and a ceramic substrate by forming a glass layer in a pattern margin presented between an electrode for adhering a semiconductor chip and an external lead electrode provided at the periphery of the electrode. CONSTITUTION:A glass layer 8 is formed in a pattern margin 4 presented between an electrode 1 for adhering a semiconductor chip on a ceramic substrate 5 and an external lead electrode 2 formed on the periphery of the electrode 1. The layer 8 is formed of the same glass as that of the overcoating layer 3 printed, for example, on the substrate 5. Thus, when a semiconductor chip 7 is sealed with sealing region 6, the expansion difference in the case of receiving a thermal impact is not extreme since the thermal expansion coefficient of the layer 8 is smaller than that of the substrate 5 and larger than that of the resin 6, and the exfoliation of the resin 6 from the substrate 5 can be eliminated.

Title: Local air conditioner
Inventor: TAKEDA MASAAKI
IPC: F24F11/02
Filed: 1988-01-29
Abstract: PURPOSE:To enable air-conditioning intensity at other local spaces to be unchanged even if the air-conditioning intensity at a certain local space is modified according to the preference of a worker, by adjusting the opening degree of a damper B in accordance with the opening degree of a damper A and by controlling the sum of a draft at an outlet port and a draft at a shunt port so as to be constant. CONSTITUTION:In the case where the opening degree of a damper A6alpha is reduced in order to slightly weaken air-conditioning intensity at a local space Zalpha, an instruction is sent through a control line 7 to a damper B9 to increase the opening degree of the damper B9 by the reduced rate of the opening degree of the damper A6alpha. Generally, in accordance with the sum of the opening degrees of the dampers A6alpha-6beta which adjust the air-conditioning intensity at the local spaces, the damper B9 is governed so as to be closed when the sum becomes large, and the same is governed so as to be opened when the sum becomes small. Further, if the sum of a draft at outlet ports 5alpha-5beta and a draft at a shunt port 8 is adjusted to be constant, the air-conditioning intensity at the local space Zalpha and that at a local space Zbeta are not affected by each other. According to this method, a local air conditioner having such a constitution as not to change air-conditioning intensity at other local spaces, even if the air-conditioning intensity at a certain local space is modified according to the preference of a worker, can be realized.
