摘要： PURPOSE:To accelerate the dissolving and removing reaction of the oxide on a metallic surface in the stage of dissolving and removing the oxide with a neutral washing liquid having weak corrosiveness by incorporating hydrogen in the washing liquid and bringing the metal to be treated into electrical contact with the other specific metal. CONSTITUTION:Electric current is conducted between an anode 8 and a cathode 7 of an electrolytic cell 1 segmented by a cation exchange membrane 6 to an anode chamber 4 and a cathode chamber 5 from a DC power source 9 to electrolyze the neutral washing liquid circulated in the cell 1 to a dissolving cell 2 by a pump 3. H2 is generated by the cathode 7 and the washing liquid 10 contg. H2 is circulated to the inside of the cell 2. A metal 11 requiring dissolution and removal of the oxide on the surface is dipped in the cell 2 and at the same time a Pt, Pd, Ni, steel, stainless steel or carbon piece 12 is dipped therein and is electrically connected to the metall 11 by a lead wire 13. Electron is injected by H2 into the oxide film of the metal 11, by which only the oxide film is dissolved and removed at a high speed without corroding the base metal by the neutral washing soln. having weak corrosiveness.

摘要： PURPOSE:To detect the defect in a painted film nondestructively and readily, by periodically emitting light to the painted film, and detecting elastic waves generated on the film. CONSTITUTION:The light emitted from a xenon lamp 24 is intermittently projected on a measuring cell 16 by way of a condenser lens 12, an interference filter 26, and a light chopper 28. Elastic waves generated by the expansion and contraction of a painted film are detected by a microphone 34 and inputted to a lock in amplifier 20. The input signal from the microphone 34 is turned with the signal from a photocoupler 36, which is synchronized with the light chopper 28, and amplified by the amplifier 20. The result is displayed on a recorder 22. Thus the defects in the painted film are readily detected nondestructively.

摘要： PURPOSE:To prevent a stress, corrosion and crack from generation, with the oxidizing agent kept in a low concentration state, by monitoring the oxidizing agent concentration in the pile water, when in a transient operation of the nuclear reactor, and if said monitored concentration exceeds the reference value, by pouring a hydrazine into the pile water. CONSTITUTION:For an electrode system, that detects a concentration of solved residual oxygen and hydrogen peroxide in a pile water 10, of the pile monitor system 12, are used a sensitive SUS304 stainless steel electrode and a silver/silver choloride electrode, and when increased a concentration in the pile water 10 of the oxidizing agent, that is, the residual oxygen and the hydrogen peroxide, a natural potential of the above described stainless steel electrode becomes high, therefore, applying this fact, a detection is firstly made for whether a concentration of the oxidizing agent exceeds the reference value or not. On the other hand, in a control system 16, with said reference value stored in memory as a natural potential ET of the above described stainless steel at each temperature, when a monitored potential exceeds the above said value, a hydrazine injection system 14 is operated to pour the hydrazine into the pile water 10 lowering its oxidizing agent concentration.

摘要： PURPOSE:To reduce friction and abrasion of sliding parts of the rotary type Flon compressor by a method wherein refrigerating machine oil, consisting of the base oil of paraffin series mineral oil or the like including the multivalent alcohol ester of monocarboxylic acid and methane sulfonic acid ester, is used. CONSTITUTION:The blending ratio of the multivalent alcohol ester (b) with respect to at least one kind of base oil (a) selected from a group consisting of paraffin series mineral oil, naphthenic series mineral oil and alkyl benzene (g) is b(a+b) or 5-30wt% while the blending ratio of methane sulfonic acid ester (c) is c/(a+b+c) or 0.05-0.5wt%. The wear resistance of sliding parts of the rotary type Flon compressor may be improved with small amount of oil supplying by using the refrigerating machine oil blended within above ranges.

摘要： PURPOSE: To provide a lubricating oil for a rotary compressor of a refrigerator consisting mainly of a specified diol, in which Freon solvent is difficultly soluble and which increases the efficiency of the compressor and reduces power consumption.
CONSTITUTION: The lubricating oil for a rotary compressor contains as main component a diol of the formula (where R is H or methyl; n is 1 or higher). The diols are, e.g., diethylene glycol, dipropylene glycol and polyethylene glycol. These diols show a higher efficiency than conventional naphthenic and paraffinic mineral oils, for they have a low viscosity and Freon freezing medium (e.g. dichlorodifluoromethane) is difficult to dissolve in them.

摘要： PURPOSE:To obtain absorbing liquid of large absorbing capacity for refrigerant by using 2-imidazolidone or the like as the absorbing liquid of a fluorine-contg. halogenated hydrocarbon base refrigerant absorption type refrigerator. CONSTITUTION:As the absorbing liquid for a fluorine-contg. halogenated hydrocarbon base refrigerant absorption type refrigerator, the lower alkyl substituent such as 2-imidazolidone or 1,3-dimethyl-2-imidazolidone expressed by the general formula (where R1, R2 are hydrogan atoms or lower alkyl groups) is used. This absorbing liquid has a high rate of dissolution of refrigerant and since it is stable to the refrigerant, it improves the performance of the absorption type refrigerator.
