Title: Torque limiter
Inventor: FUKUMOTO MASAO
IPC: F16D7/08
Filed: 1986-05-31
Abstract: PURPOSE:To facilitate checking on the relative position of the input member of a torque limiter to the output member thereof by means of marking on respective positions, by constructing the outer periphery of the flange of said input member so that it can be checked together with the periphery of said output member. CONSTITUTION:A flange 2 is formed along the outer periphery of the forward end of an input member 1, said flange being provided with a plural number of holes 3. At the front of said flange 2, a ring-formed output member 4 is rotatably fitted, and the back end face of which is provided with recesses 5 at the positions corresponding to aid respective holes 3. Balls 7, each of whose diameters is larger than the thickness of said flange 2, are loosely put therein engaging with the recesses 5 respectively. The threaded cylinder 9 of a ring plate 8 is screwed around the back end of a cylindrical body 10, bringing the front surface of an inwardly protruding rim 11 into contact with said balls 7. In normal operation, a segment 17 is pressed on said inwardly protruding rim 11 by springs 13 causing said input and output members 1, 4 to rotate together. While, when excessive torque is applied on said output member 4, said output member 4 stops causing said balls to go out from said recesses 5 to push said rim 11 backwards, making said screwed-on cylinder 9 rotate so that the force of said spring 13 may be adjusted.

Title: Method of purifying nickel sulfate by acidic extraction solvent
Inventor: MAKINO SUSUMU
IPC: C22B3/32
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To enable economically removing sodium, ammonium or the like by extracting Ni from crude Ni sulfate solution in the specified pH range by acidic organic solvent, keeping the Ni content in an organic liquid phase after extraction to specified times the Ni keeping stoichiometric quantity that the extract has and performing reverse extraction by sulfuric acid after washing the Ni keeping organic phase. SOLUTION: The pH of the time when Ni is extracted from crude Ni sulfate solution by acidic organic solvent is made 6.0-7.0. The Ni content in the organic liquid phase after extraction is kept to 0.5-1.7 times the Ni keeping stoichiometric quantity that the extract has. In a washing process for the Ni keeping organic phase, water solution containing Ni whose quantity is equal to that of the Ni keeping organic phase is preferably used as washing liquid. In this way, strong washing of the Ni extraction organic phase by a lot of washing water is not needed, and highly pure Ni sulfate solution can easily be obtained.

Title: Conductive microfilter
Inventor: MUTOU YOSHIHIKO
IPC: B01D71/06
Filed: 1984-06-21
Abstract: PURPOSE:To prevent the danger of fire or electric shock caused by the generation of static electricity when a non-conductive substance such as oil is filtered, by using a conductive microfilter consisting of an olefin resin or a fluorocarbon resin and carbon black and having a specific range of apparent volume resistivity and an average pore size. CONSTITUTION:An olefin resin such as polyethylene or a fluorocarbon resin such as polychlorotrifluoroethylene, to which carbon black was added, is formed into a hollow yarn like membrane to form a microfilter. At this time, the amount to be added of carbon black is regulated so as to adjust apparent volume resistivity to 10<4>-10<-1>OMEGA.cm and an average pore size to 0.01-1mum. By this method, a conductive microfilter is obtained and the generation of static electricity by friction between the microfilter and a liquid at the time of filtering is eliminated.

Title: Check valve
Inventor: KIKUCHI NOBUO
IPC: F16K15/02
Filed: 1983-07-13
Abstract: PURPOSE:To provide a check valve which can lessen pressure loss at the time of flowing forward and can reliably operate to flowing backward at a very small flowing speed by urging a diaphragm for blocking up a hole of a cap body along the axis of a passage. CONSTITUTION:Load is worked upon a diaphragm 31 through a spring bearing 48 by a spring 49. When a fluid flows from the upper stream, the diaphragm 31 is pushed to the downstream, and bent. In this case, if the flowing speed of a fluid is low, the diaphragm 31 is held at a point where the fluid pressure applied to the diaphragm from the upper stream and the spring reaction force applied thereto from the downstream are balanced. When the flowing speed of a fluid is high, the diaphragm 31 is moved downstream for the distance limited by a movable rod 38 to open a valve to the full. If the flow of a fluid stops, the diaphragm 31 is returned to an assigned position by the spring 49 so as to reliably check the backward flowing of a very small flowing speed.
