摘要： PURPOSE:To increase the amount of heat accumulated per unit volume, by a method wherein at least one substance selected from the group consisting of Na4P2O7, Na4P2O7.10H2O, Na3HP2O7, Na2H2P2O7 and NaH3P2O7 is added to sodium acetate trihydrate as a nucleating agent. CONSTITUTION:To restrict overcooling of a system wherein a major constituent is a eutectic crystal comprising sodium acetate trihydrate NaCH3COO.3H2O as a component, at least one substance selected from the group consisting of sodium pyrophosphate Na4P2O7, sodium pyrophosphate decahydrate Na4P2O7.10H2O, trisodium monohydrogen pyrophosphate Na3HP2O7, disodium dihydrogen pyrophosphate Na2H2P2O7 and monosodium trihydrogen pyrophosphate NaH3P2O7 is mixed into the system as a nucleating agent for NaCH3COO.3H2O. Accordingly, a stable heat-absorbing and heat-releasing capability substantially free from overcooling can be obtained, and the amount of accumulated heat is increased.

摘要： PURPOSE:To cheaply obtain the heat accumulating material with stable heat absorbing and releasing performances and with large heat accumulating capacity by a method wherein the composition percentages of three components or CaCl2, CO(NH2)2 and H2O are changed in order to control the temperatures, at which the heat accumulation and heat radiation are performed respectively. CONSTITUTION:The components or main components of the heat accumulating material are CaCl2, CO(NH2)2 and H2O. The preferable components are 40- 57.7wt% of CaCl2, no more than 30wt% (excluding 0wt%) of CO(NH2)2 and 30- 52.5wt% or H2O, with the sum of said three components is 100wt%. The more preferable components are the composition, in which CaCl2.6H2O and CaCl2. 4CO(NH2)2.2H2O form both end component and CO(NH2)2 is no more than 25wt% (excluding 0wt%) of the sum of CaCl2, CO(NH2)2 and H2O. That is to say, the temperature, at which the heat accumulation and heat radiation are performed, can be controlled by changing the composition percentages of said three components, resulting in obtaining the heat accumulating material with stable heat absorbing and releasing performances and with large heat accumulating capacity.

摘要： PURPOSE:To improve the reliability of the heat accumulator in case of repeating the heating and cooling thereof by a method wherein a supercooling inhibitor for a heat accumulating material is received in a branch projecting from a heat accumulating tank to keep the temperature of the heat accumulating material in stable state. CONSTITUTION:If the temperature of the heat accumulating tank 1 rises up to about 85 deg.C after melting, a part of the supercooling inhibitor (Na4P2O7.10H2O) 4 will never be changed in the properties thereof since the branch 2 is projected into air and is cooled by the air, and thereby being stored without loosing the function of the supercooling prevention. Upon cooling, Na4P2O7.10H2O functions as the supercooling inhibitor for the heat accumulating material (NaCH3COO... 3H2O) 3, the supercooling is interrupted at the temperature near 56 deg.C and it rises to 58 deg.C, which is the solidifying temperature of NaCH3COO.3H2O, then, the heat of solidification is discharged.

摘要： PURPOSE:A heat-accumulating material capable of suppressing supercooling of calcium chloride hexahydrate and accumulating or discharging heat at an adequate temp, which is obtd. by incorporating potassium bromide in a main component consisting of the calcium chloride hexahydrate. CONSTITUTION:Potassium bromide is added to and mixed with a main component consisting of calcium chloride hexahydrate. It is pref. to add 0.1-5pts.wt. potassium bromide to 100pts.wt. calcium chloride hexahydrate. With less than 0.1pt.wt. potassium bromide, although a supercooling-preventing effect is recognized, the potassium bromide gradually dissolves and is increasingly supercooled as melting and solidification are repeated, while with more than 5pts.wt., although supercooling is sufficiently effectively prevented, the heat-accumulating material, is unsuitable for practical use because its m.p. is markedly lowered.

摘要： PURPOSE:To separate nitrogen and carbon dioxide or nitrogen and oxygen in air by utilizing differece of solubility of a gas component to a liquid. CONSTITUTION:After a water cooler 14 and an air cooler 15 are operated, rotary pumps 10, 11 for pumping up a carbon dioxide.oxygen conveying liquid are simultaneously operated to recirculate the above described liquid 1 between a carbon dioxide.oxygen absorbing tank 2 and a discharge tank 3. After this operation, a heater 13 is operated to hold the above described liquid 1 in the discharge tank 3 at a temp. in the vicinity of the boiling point thereof and a rotary pump 12 for pouring air in a sealed chamber is operated to send air in the sealed chamber into an absorbing tank 2. After this operation, the pump 12 is stopped and the above described liquid 1 in the discharge tank 3 is cooled to a temp. in the vicinity of a room temp. and the pumps 11, 12 are simultaneously stopped and the operation of the coolers 14, 15 is stopped. As the result, the carbon dioxide component and the oxygen component in the mixed gas are entirely discharged into the atmosphere and most of the nitrogen component is recovered in the sealed chamber.

摘要： PURPOSE:To achieve photosensitive plate under simple manufacturing method and at low cost, having outstanding photoelectric sensitizing and nontoxic properties, by using phthalocyanine compound and binder composed of polysiloxane resin containing OH- or alkoxy-radical. CONSTITUTION:Coating solution is prepared by mixing and dispersing phthalocyanine pigments available in market and the binder which is typically composed of 10-90wt% polysiloxane resin containing -OR radical (R being H, CH3, C2H5, C3H7, or C4H9) and polyurethane resin for the rest, into solvent such as the mixed solvent of butyl acetate and xylene. Said coating solution is then coated over the photocondutive supporter such as aluminum plate which is then dried and then the electrophotographic receptor is completed. The electrophotographic receptor thus accomplished is provided with outstanding surface smoothness, greater charge potential by corona discharge impression, faster damping by light irradiation, and lesser residual potential.
