摘要： PURPOSE:To improve the efficiency of transporting natural gas by performing heta exchange between pressurized natural gas and condensed water of a staeam turbine, and heating the condensed water with heat of exhaust gas of a gas turbine. CONSTITUTION:Natural gas pressurized by compressors 2, 4 is cooled by a heat exchanger 16 and transported to a consumption place. Condensed water of a steam turbine 3 for driving the compressor 4 is supplied as a cooling fluid to the heat exchanger 16. The condensed water heated by the heat exchanger 16 is further heated with exhaust gas of a gas turbine 1 for driving the compressor 2 by a waste heat boiler 9, and then supplied to the steam turbine 3. Therefore, waste heat from the gas turbine and heat which natural gas has are collected without being wasted to transport natural gas with good efficiency.

摘要： PURPOSE:To obtain the spherical superfine particles which are extremely narrow in grain size distribution and have high purity by controlling the concn. of the reaction formed particles with the quantity of the light transmitted through a fine liquid drop group or solid fine particle group as a controlled variable and the concn. of the raw material sent into a reactor as a manipulated variable. CONSTITUTION:Gaseous nitrogen contg. the alkoxide emitted from an alkoxide evaporator 1 in a satd. state is mixed and diluted with the gaseous nitrogen sent from a branch path 6 via a flow rate control valve 11 from a cylinder 10. Further, this gaseous mixture is mixed with the gaseous nitrogen contg. the steam emitted from a water evaporator 2 in a satd. state in a nucleus generator 4 where the seed particles to constitute nuclei are formed by a hydrolysis reaction. The gas contg. the seed particles is cooled in a condenser 5 to a supersatd. state and is subjected to nuclear condensation with the seed particles as nuclei and is thereby made into a liquid drop aerosol. This liquid drop aerosol is sent to a main reactor 8. The alkoxide of the liquid drops sent to the main reactor 8 is mixed with the excess amt. of the steam sent from the water evaporator 3 in the above-mentioned reactor and the individual liquid drops are changed by the hydrolysis reaction to the solid particles. The solid particles formed in such a manner are captured by the filter of a capturing device 9.

CONSTITUTION:A freezing unit 3 and a sherbet-like-ice making machine 4 are operated using night electric power to convert a fusion latent heat storage agent stored in a melted liquid storage 5 into a sherbet-like cold latent heat storage agent of 50% ice that is stored in a cold latent heat storage tank 6. Before operating a train, a loading valve 9a provided on the rear car of the train is connected to a sherbet supply line 9 to transfer the cold latent heat storage agent from the cold latent heat storage tank 6 to cold heat storages 13 in the cars 1 in parallel by a sherbet supply pump 7. During operation, the air inside the cars is circulated by indoor blowers 16, and cold latent heat storage agents in the cold heat storages 13 are circulated to heat exchangers 15 by slurry pumps 14 to cool the inside of the cars without affecting the thermal environment in tunnels and platforms.

摘要： PURPOSE:To ensure that a traveling truck, powered by the rotation of a propeller which rotates due to a fluid in a tubular interior, can travel easily overcoming the flow speed of the fluid, then the flow speed on a tubular inner surface of the fluid in a tube is accelerated and foreign matter is prevented from sticking to the tubular inner surface properly by a brush attached to the traveling truck. CONSTITUTION:A propeller 3 which rotates due to the flow of a liquid in a pipe A is installed in the center of a traveling truck 1 with wheels 19a to 19b which travels in the pipe A. The rotation of the propeller 3 is transmitted to clutches 12, 13 which freely rotate around a rotating shaft 7 through gears to 10a to 10d and reduction gears 11a to 11d, and the rotating shaft 6 is allowed to rotate by shifting clutches 15, 16 which rotate with the rotating shaft 6, being able to engage itself with the clutches 12, 13. Thus the rotation of the rotating shaft 6 is transmitted to wheels 19a 19b by a gear mechanism to move the traveling truck 1.

摘要： PURPOSE:To make molten slag of a blast furnace resources of good quality water-granulated slag at the same time, to recover a large quantity of exhaust heat at a high temp. CONSTITUTION:In the method which produces the water-granulated slag 10 by jetting water to the molten slag 1 of the blast furnace, etc., in a slag cooling vessel 6 and rapidly cooling and also recovers the generated heat directly through a heat exchanger, the slag cooling vessel 6 is operated in the atmosphere. A slag supplying tube 2 for supplying molten slag 1 has so sufficient cross sectional area as to be able to correspond to the variation in the molten slag supplying quantity and is made to flow without filling up the molten slag. In order to prevent suction of the air into the slag cooling vessel 6 through the upper space of the slag supplying tube 2, on the way of the slag supplying tube 2, suction gas exhaust parts 3, 4 having a little lower pressure than the atmosphere are arranged. By using such equipment, the heat is recovered by heat exchangers 17, 18 from steam directly generated by the heat exchange.

CONSTITUTION:A block x is clamped from above and below with a comb-shaped cutting guide 1 and laterally cut with a band saw 4. The cutting is stopped immediately before the base of the comb tooth of the guide 1 to leave middle bones Y and small bones y as they are. The cutting direction of the block x is changed and the block is cut by the same means to cut the block in the direction of thickness until the saw is passed through the opposite end. The remaining middle bones Y and the small bones y are removed to complete the dressing operation.
