Abstract: PURPOSE:To prevent the corrosion of a frame and to minimize an installation space by using concrete in making supply and draining sections for waste water and the frame. CONSTITUTION:The waste water flowing into a conduit trough 1 made of concrete passes through a flow equalizing plate 5 then through a top part and flows while it is accelerated downward. The waste water is further regulated of flow uniformly in the overall width direction of a screen deck 3 by a flow regulating plate 8. The solid materials in the waste water are separated by the deck 3, and flow into a draining channel 4 made of concrete in the lower part of the deck 3. The solid materials on the deck 3 glide down by own-gravity on the deck 3 of an acute angle and are stopped once by a slope in the lower part. The solid materials removed of drains in such a way are pushed by the succeeding solid materials so as to fall onto a trough 5 made of concrete form the front end of an apron 9. If the deck 3 is supported rotatably, slime is easily removed.

Abstract: PURPOSE: To make a supporting frame needless and to increase a maintenance space by a method wherein an auxiliary operating valve is installed on an oil tank wall of the titled device used in a large bulldozer, etc. and the input side thereof and an operating lever are coupled with a link mechanism.  
     CONSTITUTION: When an operating lever 23 is operated to actuate an auxiliary operating valve 4 through a lever link mechanism for tilting, an output is amplified and an operating valve 2 for tilting is actuated. In the same way, an auxiliary operating valve 17 for lifting is operated by means of the operating lever 23 through a lever link mechanism for lifting and an operating valve 2' for lifting is actuated. In this case, since the operating lever 23 and the lever link mechanism are retained in the auxiliary operating valve 4 for tilting, the amplification operating force has a reaction force point on the tank wall, as a result, the auxiliary operating valves 4, 17 are held on the wall of the oil tank 1 through a piping element 3 and a supporting frame is made needless without strengthening the the bearing leg part, thus, increasing the maintenance space.

Filed: 1986-07-14
Abstract: PURPOSE:To maintain the accuracy of measurement and to shorten the time for preparing the measurement by isolating a plasma torch and nebulizer thermally and housing a sample soln. supplying part into a shielding box. CONSTITUTION:The nebulizer 1 is housed into an analyzing instrument box 3 by being partitioned by a partition plate 4 so as to isolate the same from the high-temp. atmosphere generated from the plasma torch 2.

Abstract: PURPOSE:To remarkably increase the etching multiplying factor by passing Al foil through the inside of a main etching vessel having a bottom shielding plate in a liq. etchant dipping tank when the Al foil is etched in the etchant by applying an electric current with the foil as an anode. CONSTITUTION:When the surface of the Al foil for an electrolytic capacitor is etched in the production of the foil, the Al foil 11 is passed through the inside of the etchant 12 in the dipping tank 13 through a feeder roll 20, directed upward by a turning roll 22, passed between the bottom shielding plates 15 and 16, and introduced into the main etching vessel 14. An electric current is supplied between the foil 11 as the anode and cathodes 17 and 18, and the surface of the foil 11 is etched. Since the leakage of the etching current is interrupted by the bottom shielding plates 15 and 16, the electric current increases rapidly at the initial stage, the effect of the gas generated during etching is mitigated, and the Al foil is etched at a high rate.

Abstract: PURPOSE:To reduce a heat resistance at the time of drive of an electronic component module and to prevent the malfunction of mounted electronic components and damage to the components by a method wherein a roughened part is formed in the surface of each wiring board. CONSTITUTION:Respective outside surfaces 2a of multilayer interconnection boards 2 and 2 are cut off in a sawtoothed section and roughened parts 6 are formed in the surfaces 2a. When this semiconductor IC module 1 is driven, heat generated from semiconductor ICs 3... is transmitted to the boards 2 and 2 through connecting terminals 5 and the like and is dissipated from the boards 2 and 2 to the outside space.

Thereby, a heat resistance at the time of drive of the module 1 is reduced, the fact that the interior of the module is filled with the heat is eliminated and the fact that the ICs 3... are malfunctioned or damaged is eliminated.
