Title: Method for packing pyrolytic carbon
Inventor: TANAKA NORIYUKI
IPC: C04B41/46
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To pack pyrolytic carbon up to the center part of a porous base body such as a carbon fiber formed body without causing any ununiformity of the density in a relatively short time. SOLUTION: A liquid organic material 7 is sprayed from a nozzle 5 to be brought into contact with the carbon fiber formed body 2 while heating the carbon fiber formed body 2 of the porous body to be 1300 deg.C in the center part temp. by a high frequency induction heating coil. The temp. of the surface part of the carbon fiber formed body 2 is made lower than that of the center part by vaporizing the organic material 7 to take heat away from the surface of the carbon fiber formed body 7. Then, the gaseous organic material vaporizing on the surface of the carbon fiber formed body 7 does not cause very much pyrolysis in the vicinity of the surface to easily diffuse toward the center part and rapidly pyrolyzed in the center part having relatively high temp. As a result, the carbon fiber formed body 2 is filled with the pyrolytic carbon successively from the center part.

IPC: C02F3/00
Filed: 1987-07-17
Abstract: PURPOSE:To execute dephosphorization and denitrification simultaneously in a single batch-operated reaction treatment stage by housing and disposing iron contact materials into a batch-operated reaction vessel which repeats an aerobic treatment and an aerobic treatment and combining this reaction vessel and an ultrafilter tank disposed behind said vessel. CONSTITUTION:The batch-operated reaction vessel 10 in the state of introducing night soil therein forms the treatment stage to alternately repeat the aerobic state and the an aerobic state with time limitations by operation of an aerator 11. The phosphorus in the night soil is exessively taken into sludge during this time. This sludge releases phosphoric acid ions in the an aerobic state. On the other hand, the iron contact materials 12 in the reaction vessel 10 elute iron ions by the adhesion of the org. materials in the night soil thereon and form iron phosphate by reacting chemically with the phosphoric acid ions. The denitrification is executed simultaneously with the dephosphorization when this iron phosphate is taken into the sludge. Since the iron phosphate acts as a flocculating agent, COD and SS components are surely captured and removed in the ultrafilter tank 14 in which the supernatant liquid is introduced.

Title: Power switching device
Inventor: TAKAHASHI MITSUGI
IPC: H01H9/36
Filed: 1987-07-15
Abstract: PURPOSE:To make high-voltage interruption operable easily by disposing an intermediate electrode so that it faces a tip part of a movable electrode during the opening of both contacts and it faces an extinction plate and it covers both the tip part and the extinction plate. CONSTITUTION:A positive column of an arc generated between contacts 3 and 4 during the opening of the contacts is attracted in the direction of an extinction plate 6 by a magnetic action of the plate 6. Gases of high temperature and of high pressure is generated from the positive column of the arc, and these gases are made to flow outward from an extinction chamber while temperature of them is being lowered by adiabatic expansion. The flow of them upward the extinction chamber is not interrupted midway because of a U-shaped flow on the plate 6, and they are made to impinge directly on a surface of an intermediate electrode 10 since the upper part of the extinction chamber is covered with this electrode 10. Consequently the gases receive adiabatic compression in the vicinity of the electrode 10 and so temperature rises. When an arc foot on a fixed contact 3 is carried to an arc runner 11, the positive column is tried to move to the inner part of the plate 6 by a magnetic action of the plate 6, so that two arcs are generated between a tip part 9 and the electrode 10 and between the electrode 10 and the runner 11 respectively. Accordingly high- voltage interruption can be operated easily.
