摘要： PURPOSE:To realize an electrolytical corrosion-proof transformer tank with simple installation by burying said tank in an underground hole made of reinforced concrete and disposing a sacrificial anode via an insulated wire in said hole. CONSTITUTION:In a galvanic anode method, a transformer tank 2a is buried in an underground hole 1 made of reinforced concrete and is connected to a grounding bar 7, reinforcing bars 6 and a sheathed earth 12 via insulated cables 12. A sacrificial anode 11 is installed via the cable 12 in the hole 1. When the tank 2 is submerged in the water in the hole 1 and corrosion is to initiate, the sacrificial electrode 11 submerges in the water 16 as well and provides an electrolytic protection effect. Thus, the transformer is protected electrolytically with the simple installation.

摘要： PURPOSE:To detect a corrosion current of a metallic tank of an underground transformer as it is in a working state, by measuring in advance a resistance value between an earth terminal and a base terminal before the transformer is buried, and measuring a potential difference between measuring terminals after the transformer has been buried. CONSTITUTION:On the upper part of a metallic tank 1 having a cooling fin 1a, a terminal chamber 1b is formed and a terminal base 2 having a pair of measuring terminals 2a, 2b is provided. On the other hand, an earth terminal 3 is installed to the upper part of the tank 1, also a base terminal 10 is installed to a lower base 1C, and the terminal 2a and the terminal 3, and the terminal 2b and the terminal 10 are connected respectively. As for such a transformer, before it is buried, a resistance value R between the terminal 3 and the terminal 10 is measured in advance. Subsequently, the transformer is installed in an underground hole 6, and an earth rod of ground 13 is connected to the terminal 3 with an earth wire 8. When the transformer is installed in this way a potential difference (e) between the terminal 2a and 2b, a corrosion current (i) shown by the expression is derived and an advancing state of corrosion is monitored.

摘要： PURPOSE:To heat water in the bathtub in a short period of time without requiring much power consumption by heating the water in the bathtub by making use of accumulated heat. CONSTITUTION:The heat accumulating tank 2 comprises a heat accumulating material 4 to accumulate the heat released from an electric heater 3 and a heat insulating material 5 surrounding the heat accumulating material 4. The heat accumulated in the heat accumulating material 4 is received by a heat transmission pipe 6. The water circulation passage 9 has connecting pipes 7a, 7b respectively between the both ends of the heat transmission pipe 6 and the interior of the bathtub 1 to allow the circulation of water between the heat transmission pipe 6 and the interior of the bathtub 1. As the water in the bathtub is heated by making use of heat accumulated in this manner, the additional heating can be completed in a short period of time without requiring much power consumption.

摘要： PURPOSE:To provide a heat value required to additionally heat the water in the bathtub in a short period of time by making up a heat accumulating tank with a heat accumulating material to accumulate the heat generated by an electric heater and a heat insulating material surrounding the same, and transmitting the heat stored in the heat accumulating material through a heat pipe to the water in the bathtub. CONSTITUTION:The heat accumulating tank 2 comporises a heat accumulating material 4 to accumulate the heat released from an electric heater 3 and a heat insulating material 5 surrounding the heat accumulating material 4. A heat pipe 6 which has a heat collecting part 6b on the side of the heat accumulating material 4 transmits the heat accumulated in the heat accumulating material 4 to the water in the bathtub 1 through the heat releasing part 6b. The heat pipe 6 has on its way a valve 7. By this arrangement, a heat value required to additionally heat the water in the bathtub can be provided in a short period of time without requiring much power consumption.

摘要： PURPOSE:To conduct suitable heating of hot water in accordance with season and reduce a heat radiation loss due to residual hot water by fitting a temperature sensor at a position where receives the thermal influence of both the temperature of hot water within a hot water storage tank and the external air temperature to detect the external air temperature, and using a memory element. CONSTITUTION:A comparator 8 compares the detected temperature of a temperature sensor 6 with data within a lowest temperature memory element 9, and gradually renews the lowest temperature to stores the same within the lowest temperature. A heater controller 12 conducts power supply to a heater 2, and when the detected temperature of the temperature sensor 6 has been raised up to a heating temperature which is the result of the operation of an arithmetic unit 11, the heater controller 12 stops the power supply to the heater 2. In winter season where the external air temperature is low, the temperature sensor 6 detects a temperature which is lower than the temperature of hot water within a hot water storage tank 1. Therefore, the temperature within the hot water storage tank 1 becomes higher than the result of the operation of the arithmetic unit 11. In view of the above matters, the amount of hot water stored in the electric hot water heater can be reduced in term of the amount of hot water of 45 deg.C, and increased in summer season.

摘要： PURPOSE:To reduce the light loss of a luminous tube and improve the luminous efficiency by forming a light reflecting film on the facing portion of tube walls separated and facing to each other of a luminous tube bent in a U-shape and made in a saddle shape. CONSTITUTION:A luminous tube 13 is stored in a globe 11. The bulb 17 of the luminous tube 13 is formed in a bent section 16 with a near U-shape at the middle between both end sections 19, 19 of the straight line bulb and is also formed in a pair of U-type sections 14, 15 bent nearly in a U-type in a direction nearly at a right angle to a plane including the U-shape between the bent section 16 and both end sections 19, 19. Thereby, straight line sections 20a-20d connecting the end sections 19, 19 and tops of U-type sections 14, 15, and the tops and the bent section 16 are arranged in parallel at diagonal positions of a square to form a saddle shape. A light reflecting film 25 is coated on the inner surface of facing portions between the straight line sections 20a and 20c, and between 20b and 20d along the tube axis direction, then a phosphor film 22 is coated on the inner surface of the bulb 17. Accordingly, the light loss of the luminous tube can be reduced and its luminous efficiency can be improved.
