摘要： PURPOSE:To improve yield per unit area by periodically moving a culture bar planted with hydroponic stocks at regular spaces, thereby expanding the occupying area of the hydroponic stock according to the growth of the stock. CONSTITUTION:A plurality of pots 3 are attached at regular intervals to a bar main body 2 having a mirror-symmetric shape. A urethane block 4 holding a culture plant root passing through the block is inserted into each pot to obtain a culture bar 1. The bar is suspended with a pair of holding tools of a crab 7 placed on beams 9 of a girder 8 of a spacing robot 6. Hydroponic culture of the plant is carried out by suspending the bar on a culture liquid bed 5 placed between a pair of girder traveling rails 12. The crab 7 on a crab- traveling rail 10 and the spacing robot 6 are moved in the directions of X and Y, respectively, according to the growth of the hydroponic stock to widen the space between the pot 3 and the culture bar 1 and expand the occupying area of the hydroponic stock.

摘要： PURPOSE:To miniaturize the title device by supplying power to an induction coil or an electric heater upon heat storage operation to heat a metal heat storage body and store heat therein, and evaporating supply water fed into an evaporation chamber and feeding produced vapor directly to a contact type heat exchanging water tank to produce hot water upon heat dissipation operation. CONSTITUTION:In heat storage operation, midnight power is supplied to an induction coil 5 through an electric wire 11 and a switch 12 to heat a heat storage body 2 and store heat. When the heat storage body 2 rises in temperature to that predetermined, the switch 12 is switched off by an instruction from a temperature sensor 13. In heat dissipation operation, water is supplied into an evaporation chamber 4 through a water supply system 6 and a flow control valve, and simultaneously into a water tank 8 through a water supply system 9 and a flow control valve 15. The water introduced into the evaporation chamber 4 is heated by the high temperature heat storage body 2 and evaporated, and produced vapor is stored in the water tank 8 through a vapor take-out system 7 and discharged into water 16 to produce hot-water. The produced hot-water is taken out through a hot-water take-out system 10 and a pump 17. Hot-water is effectively produced and supplied to consumers.

摘要： PURPOSE:To effect efficient leakage detecting work by a method wherein a hot-wire anemometer, equipped with a coil type heat sensing unit with a diameter substantially equal to the outer diameter of a cooling tube, is provided in an abutting box, abutted against the outside of a tube plate and obtain a vacuum condition in the box and the cooling tube. CONSTITUTION:An abutting box 18 is applied to the outside of a tube plate 6 to keep the inside of cooling tubes 4 and the abutting boxes at both sides of cooling tubes in a vacuum. The tip end coil type heat sensing unit 23 of a hot wire anemometer 22, sealed by a packing 21, is located in the abutting box 18 and the heat sensing unit 23 opposes to the outer diametral section 24 of the cooling tube 4 while the fluctuation in a voltage, which is generated in conjunction with the reduction of temperature due to inflow air when there is leakage, is amplified and is read at the outside of the box as the changing value of an electric current. The coil type heat sensing unit 23 is constituted so as to be capable of traversing on the tube plate 6 while sliding along the packing 21. The degree of vacuum is not constant, therefore, another sealed chamber 26 which shields the periphery thereof from leaked air and another hot-wire anemometer 22' are prepared separately to compare the measured values of these two hot wire amemometers 22, 22'.

摘要： PURPOSE:To ensure safety in case of power loss, by providing a spring reaction removing means for canceling a reactive force of a spring to a change nut provided on an output shaft of planetary gears. CONSTITUTION:A rotary motion of stepping motors 1 and 2 is transmitted through a planetary gear 51 to a screw shaft 24. The screw shaft 24 provides for a linear motion to a change nut 25 having a stopper 26 to control an output oil pressure of an electric-hydraulic converter in proportion to a compressive force of springs 43 and 44. A lever 39 is branched at a lower end portion of a hook 40, and is connected to the change nut 25 by a screw. Even when the stepping motors lose a restrictive force upon power failure, the change nut is restricted by the operation of the hook to be hindered from rising, thus maintaining a controlled oil pressure just before the power failure.

摘要： PURPOSE:To ensure titled head, by increasing the flow rate of water passing through a pump by detecting the sudden change or interruption of the loads of a turbine. CONSTITUTION:An analog signal proportioned to the output of a turbine is produced by means of a turbine 1st stage pressure transmitter 19, and the signal and a signal obtained by passing the signal through a primary delay computing element 20 are subtracted by means of an addition and subtraction computing element 21, thus gaining an analog signal proportioned to the coefficient of the variation and the quantity of the variation of the output of the turbine, then acquiring an ON-OFF contact signal. When there happens the sudden reduction of loads, the pressure of turbine bleed to a deaerator 5 lowers in approximately proportional to the loads of the turbine at short time-lag, but pressure in the deaerator drops at a suitable pressure drop ratio, and pressure in the deaerator temporarily becomes higher than the pressure of turbine bleed, thus totally closing a check valve 23 of the bleed of the deaerator mounted to a piping of the turbine bleed 6, then ensuring the effective net suction head of a pump.
