摘要： PURPOSE:To bring a capillary tube body into close contact with the inner wall of a heat transfer pipe whatever a sectional shape thereof is, by forming the capillary tube body by a method wherein solder or a waxy adhesive is melted on the inner wall of the heat transfer pipe by heating or non-heating, forcing fine powder and a fine fiber material to adhere to the melted portion, and solidifying the adhesive. CONSTITUTION:A heat transfer pipe manufacturing apparatus comprises a heat transfer pipe 1 adapted to be freely rotatable via a bearing 8, a heater 5 for heating the heat transfer pipe, and a blower 6 and a piping 7 mounted on opposite ends of the heat transfer pipe 1 for circulating a fine powder sample as a raw material of a capillary tube body and fine fibers 2. The piping is constructed in the form of a loop. Since on the inner wall of the heat transfer pipe an adhesive has been melted, scattered fine powder sample and fine fibers are forced to adhere to the adhesive. Thereupon, as heating by the heater 5 is interrupted to solidify the adhesive, the fine powder sample and fine fibers forced to strongly adhere to the inner wall for formation of the capillary tub body. With this method, chemical adhesives are available in addition to melted metal materials such as solder and wax.

摘要： PURPOSE:To remove the practical limitation in a conveyance distance for a fluid by a method wherein a magnetic fluid (superconductive fluid) mixed with superconductive corpuscles is used as a fluid for a fluid loop and a magnetic field is applied to the heat exchanging part of a heat radiating part. CONSTITUTION:At a part of a fluid loop 1 the heat exchanger 4 of a heat receiving part and at the other part the heat exchanger 5 of a heat radiating part are installed respectively. At the exchanger 5 a magnet 6 is placed around the loop 1. At the inlet part of the exchanger 5 a heater 9 controlled by a controller 8 is installed. Into this fluid loop a magnetic fluid composed of a refrigerant such as Freon 11, etc., mixed with supercondcutive corpuscles is sealed. While a superconductive fluid passes through the exchanger 5, the temp. changes from a critical temp. (Tc) or more to the temp. of Tc or less. Since a magnetic field is applied to the exchanger, the superconductive fluid at the temp. of Tc or less receives the resiliency from the magnetic field and the superconductive fluid at the temp. Tc or more hardly receives force from the magnetic field. By this difference of mutual acting forces the superconductive fluid can be circulated in the fluid loop. This resiliency is proportional to the square of a magnetic flux density at a critical magnetic field or less and there is no limitation for conveyance distance in practice.

摘要： PURPOSE:To utilize a mid-night power and provide an effective utilization of latent heat generated by a variation in phase of thermal accumulation material by a method wherein a plurality of thermal accumulation material filling chambers are provided, and thermal accumulation materials having as a substance a different melting point are filled in each of the room for respective physical properties. CONSTITUTION:A structure of a thermal accumulation tank is composed of thermal accumulation material filling chambers 25-27 divided into three sections in a gravity direction, thermal accumulation materials 19-21, a heat exchanging part composed of heat exchangers 7-9 and an electric heater 4 for heating tap water 5. A melting point is gradually higher toward an upper part of the thermal accumulation tank and a difference in temperature of melting point of each of thermal accumulation materials is about 10 deg.C so that a relation of the melting point of each of the thermal accumulation materials satisfies the relation 19>20>21. When the thermal accumulation materials within the thermal accumulation tank is to be melted, the materials are heated by the electric heater until a water temperature in a temperature sensor 11 reaches about 90 deg.C in such a way as all the thermal accumulative materials are melted and then the materials are melted in sequence from the upper part to the lower part under a natural convection effect. The electric heater is utilized from 0 o'clock at mid-night to 8 o'clock in the evening and a time band in which the latent heat generated simultaneously with a heat energy of the melted thermal accumulation material is utilized ranges from 8 o'clock in the morning to 0 o'clock at mid-night.

摘要： PURPOSE:To prevent the selective adsorbing surface of a heat collecting plate from deterioration resulting from the surface being overheated by the radiant heat of the sun by a method wherein in the titled heat collector in which a heat collecting body is sealed in a vaccum glass tube, a reflecting plate is arranged between a part of the glass tube to be heated at the time of vacuum sealing and the heat collecting body. CONSTITUTION:The heat collecting body comprising a heat collecting plate 2 and a heat collecting pipe 3 is sealed in the vacuum glass tube 1. In this case, the reflecting plate 6 in the form of a plain aluminum disk is provided between the heat collecting plate 2 and a vacuum sealing end 5 of the glass tube 1 so that the selective adsorbing surface of the heat collecting plate 2 is protected against the radiant heat of the sun at the time of vacuum sealing the heat collecting body in the glass tube 1 and as a secondary effect, sunlight reflects on the reflecting plate 6 to become incident on the heat collecting plate 2 to thereby increase the heat collecting efficiency of the plate 2. Further, a second reflecting plate 7 is provided on the front surface of a header 4 so that sunlight reflects on the reflecting plate 7 to become incident on the heat collecting plate 6 to thereby increase the heat collecting efficiency of the plate 6, too.
