Title: Production of selective solar heat absorption material
Inventor: HAYASHI JIYUNICHI
IPC: F24J2/48
Filed: 1980-01-17
Abstract: PURPOSE: To improve a selective absorption characteristic by a method wherein an anode oxide film is formed on a surface of aluminum or its alloy, a metal is separated on a surface of the film, the surface is made to be a rough form.  
     CONSTITUTION: Aluminum is degreased, then ground with chemicals in a bath of phospher-nitride acid, a rate of reflection in a range of infrared wave length is improved, the aluminum is anode oxidized in a bath of sulfuric acid to poduce an anode oxide film having a thickness of about 10μm. Then, an electrolyte coloring treatment is performed in an electrolyte bath containing soluble metallic salt such as Ni, Co, Sn etc., the metal 3 is separated on a bore 2 of the film 1 and then colored. Upon cleaning with water, the salt is melted by mixture solution of phospheric acid and chromium acid, aluminum base metal is not melted even if the film is melted, so a solution bath having a decoloring of the film, that is, less solution of separated metal 3 is selected.

Title: Production of high-purity sulfuric acid
Inventor: KAWABATA TAKASHI
IPC: C01B17/90
Filed: 1992-01-10
Abstract: PURPOSE:To obtain a high-purity sulfuric acid with reduced metallic impurities by making SO3 gas absorb into a liquid consisting of ultrapure water and/or high-purity sulfuric acid in an absorption column packed with a material consisting of synthetic silica glass. CONSTITUTION:A specified quantity/time of liquid SO3 is introduced via a liquid SO3 introduction tube 1 into a vaporizer 2 kept at 45 deg.C where it is vaporized, and the residual SO3 is drawn via a purge tube 4. The resulting SO3 gas is introduced via a tube 3 into the bottom of an absorption column 5 packed with Raschig rings consisting of synthetic silica glass. Concentrated sulfuric acid >=90wt.% in concentration is introduced via a circulating sulfuric acid conductor 7 into the top of the absorption column and ultrapure water via the corresponding conductor 7 into the column to absorb the SO3 gas. Then the concentrated sulfuric acid after SO3 gas absorption is drawn off the bottom of the column 5, and, as necessary, is brought into contact with air in a packing column-type sulfurous acid-removing column to eliminate the contained SO2 gas, and the resultant concentrated sulfuric acid is passed through a filter 11 filtering the produced sulfuric acid to reduce the metal content (such as of Na, K and Ca) to <=1ppb, thus obtaining the objective high-purity sulfuric acid.

Title: Acoustic method and apparatus for detecting water leakage from steam evaporator heat transfer pipe
Inventor: SUZUKI TOSHIYUKI
IPC: G01M3/24
Filed: 1993-01-12
Abstract: PURPOSE:To detect water leakage from piping quickly in order to prevent the effects of the leakage from propagating. CONSTITUTION:An acoustic power signal from each virtual sound source is sent to averaging circuits 15 and arithmetic circuits 16, and then sent to effective value computing elements 17 as difference signals between preset average acoustic power at specified intervals of time and present acoustic power. The output from the effective value computing elements 17 mean the size of variations in the acoustic power of virtual sound sources. When it exceeds the limits to the normal acoustic power variations stored in an alarm setter 18, an alarm or a signal to operate the piping isolation interlock will be issued. A piping water leakage problem can be solved quickly because an alarm will be issued or the piping isolation interlock will be operated when excessive variations in the piping acoustic power are detected.

Title: Fuel injection valve
Inventor: OTA TAKESHI
IPC: F02M47/00
Filed: 1989-01-12
Abstract: PURPOSE:To prevent fuel leakage around a pressure increasing piston without requiring machining accuracy and prevent malfunction by forming the end of the cylindrical portion on the pressure increasing chamber side of a pressure increasing piston into a thick wall and elastically varying the cylindrical portion with fuel pressure and reducing a clearance. CONSTITUTION:Due to the pressure of fuel which flowed into a pressure increasing chamber 67, a pressure increasing piston 59 is pressed and a plunger 31 is also pressed to feed fuel in a plunger chamber 35 to a nozzle body 49 side under pressure. At this time, the thin-walled middle portion 65a of an upper cylindrical portion 65 is elastically spread and deformed by the fuel pressure in the pressure increasing chamber 67, causing the clearance C between the outer wall of the upper cylinder portion 65 and a sliding bore 57 to be minimum at a deforming portion, to restrain fuel leakage from the periphery of the piston 59 in the pressure increasing chamber 67. Thereby, the pressure of fuel in the pressure increasing chamber 67 acts efficiently on the piston 59 to achieving high pressurization of the pressure increasing chamber 67 efficiently while improving the responsiveness of action of the piston 59. As a result, the fuel in the pressure increasing chamber can efficiently feed the fuel in the plunger chamber 35 under pressure via the piston 59 and the plunger 31.

Filed: 1982-01-13
Abstract: PURPOSE:To surely protect an engine and prevent it from being damaged resulting in an accident by providing an abnormal oil pressure detecting means, an abnormal water temperature detecting means and a means which is communicated with those means so as to stop the engine when the oil pressure or the water tempereature is unusual. CONSTITUTION:A key switch 2 includes a starting system contact point 2S which is connected to a starter motor 3 and an ignition system contact point 2i which is connected to an ignition coil 4. When either one or both of an oil pressure switch 13 and a water temperature switch 14 is or are closed, a solenoid coil 11b of a relay switch 11 is electrified to be excited. Since a switch 11a connected to the ignition coil 4 is then opened, an ignition system becomes inoperative and the engine may be stopped. The engine is thus surely stopped if the oil pressure may be excessively reduced or the cooling water temperature may be excessively increased.
