Title: Production of composite solder material
Inventor: FUKUMAKI TAKASHI
IPC: B23K35/40
Filed: 1985-04-03
Abstract: PURPOSE:To obtain the solder which itself has high strength and a soldered joint having a superconductive characteristic by heating the grains, powder or fiber of a metal which improves the characteristics of the solder and the solder under no gravity at the temp. near the melting temp. of the solder and mixing the same. CONSTITUTION:For example, Bi-Pb solder and the powder of Nb-Ti which exhibits the superconductive characteristic in liquid He are weighed and are put into a crucible 1. The mixture thereof is heated by an electric furnace 2. The Bi-Pb is melted by such heating. The mixture is thoroughly agitated at the same instant when the solder melts to disperse and mix uniformly the solder material 3 and the superconductive Nb-Ti powder 4. The mixture is extremely uniformly dispersed and mixed if the production is executed in the cosmic space. The material is thereafter cooled and the production is completed.

Title: Controller for high gear clutch built in fluid transmission
Inventor: OOTANI TAKASHI
IPC: F16H61/14
Filed: 1980-05-26
Abstract: PURPOSE: To control a high gear clutch without using electrical equipment, by mechanically detecting the racing of a stator in a high speed ratio range to open a hydraulic circuit to engage the high gear clutch and opening a centrifugal valve in response to the fall in velocity to disengage the clutch.  
     CONSTITUTION: When a pump 4 is rotating in a low speed ratio range, a stator 8 receives the velocity of flow in the pump 4 to lock up a flywheel 6. In that case, a stator shaft 7 is turned in the direction of an arrow (b) and stopped, ports 12 1 , 12 2  are disconnected from each other, a high gear clutch 9 is disengaged and pressurized oil is drained through a centrifugal valve 15. When the pump 4 is rotating in a high speed ratio range, the stator 8 races. In that case, the stator shaft 7 is turned in the direction of another arrow (a), the ports 12 1 , 12 2  are connected to each other, the centrifugal valve 15 is closed, pressurized oil is supplied to the high gear clutch 9 and the clutch is engaged. Since a hydraulic circuit for the high gear clutch 9 is thus mechanically opened and closed, electrical equipment is not needed. The constitution is thus simplified.

Title: Production of polyphenylene ether
Inventor: SOMEMIYA AKIYOSHI
IPC: C08G65/00
Filed: 1981-05-07
Abstract: PURPOSE: To prevent a catalyst from becoming unstable and deactivated during a dewatering operation, by dewatering a polyphenylene ether reaction mixture solution in a state in which part of the material phenol is present, and recirculating the dewatered solution to the polymerization system.  
     CONSTITUTION: In the continuous polymerization of polyphenylene ether, the reaction mixture is separated and the separated solution is dewatered in a state in which at least part of the material phenol is present in the separated solution, and the dewatered solution is recirculated to the polymerization system. Catalyst deactivation during the polymerization reaction of polyphenylene ether is largely due to the formation of a metal oxide via a metal hydroxide, and accordingly the presence of the material phenol as a reducing substance markedly stabilizes the catalyst. In an industrial process, it is advantageous to add a phenol between the separation and dewatering steps.

Filed: 1988-03-25
Abstract: PURPOSE:To secure the ventilation in a moving bed and to improve production efficiency by specifying the void ratio of the fine ore packed in a transport pipe at the time of separating the fine ore discharged from the recirculating fluidized bed from a gas and returning the fine ore to the fluidized bed. CONSTITUTION:The fine ore supplied from a raw material inlet 14 is fluidized by a reducing gas 13 in a riser 10, reduced, and then introduced into a cyclone 11 along with the high-speed gas. The fine ore grains alone are introduced into a downcomer 12, and returned to the fluidized bed. A part of the grains are recovered from an outlet 15. In this operation, the sorting and screening of the raw ore and the mixing of the grains having different physical properties (apparent density, shape, bulk density, etc.) are previously carried out, and the fine ore grains exhibiting >=0.40 bulk density in the downcomer 12 are used. As a result, the circulation of grains in the recirculating fluidized bed is stabilized, and the ore is smoothly reduced.

Title: Method for producing hydrate and device for producing the same
Inventor: YOSHIKAWA KOZO
IPC: C07C9/04
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently reacting a hydrate-forming substance with water to produce a hydrate in a high concentration at a high rate, and to provide a device for producing the same. SOLUTION: This method for producing a hydrate comprises reacting water with a hydrate-producing substance (for example, methane) in a hydrate- producing vessel 1 to produce the hydrate. Therein, the methane is supplied as bubbles K to an aqueous phase L, and supercooled water is sprayed 10 in an atomized state into a gaseous phase G comprising the methane filled in the hydrate-producing vessel 1. The methane introduced into the liquid phase L is partially absorbed into the aqueous phase L from the gas-liquid interfaces of the bubbles K, and reacted with the water to produce methane hydrate MH. Since the density of the methane hydrate MH is smaller than that of the water, the hydrate MH is floated on the aqueous phase. The water 10 instantaneously reacts with the methane in the gaseous phase G to produce the methane hydrate, which is lowered on the aqueous phase L.  The produced methane hydrate layer is extracted and recovered.

Abstract: PURPOSE:To obtain improved heat recovery and power generating efficiencies by a method wherein a sulfur oxide produced by partial or complete oxidation of coal is fixed and removed by carbonate while the desulfurizing performance of  used carbonate is regenerated by a part of the produced gas. CONSTITUTION:Coal is partially oxidized in a partial oxidizing zone A. Then, the gas produced in the oxidizing zone A rises to a completely oxidizing zone B where it is burnt perfectly.

CaSO4 produced by the conversion of oxides in the first reaction zone is supplied to a second reaction zone where it is converted into CaS. Here, CO and H2 gases produced in the partial oxidizing zone A are supplied through a conduit 41 into the second reaction zone. CaS produced in the second reaction zone is supplied into a third reaction zone where it is converted into CaO so that the desulfurizing capability is regenerated.
