摘要： PURPOSE:To provide the titled actuation process where, in obtaining oxygen gas fro air by pressure swing adsorption using an adsorbent, the titled apparatus is shut down in such a state that the oxygen gas has been fed to the adsorption column at the end of oxygen-enriching operation so as to obtain the oxygen gas immediately after the reactuation. CONSTITUTION:An adsorbent capable of selectively adsorbing nitrogen and carbon dioxide gases (e.g. zeolite) is first prepared. A plural of adsorption columns packed with this adsorbent are fed with pressurized air to draw out enriched oxygen. After the termination of the adsorption process, air is released to expel nitrogen gas etc., and the oxygen-enriched gas is stored in a buffer tank under a pressurized state. At the termination of these operations, the selector valve is opened and the oxygen-enriching apparatus is shut down in such a state that the oxygen gas has been fed from the above-mentioned tank to the adsorption column.

摘要： PURPOSE:To attain a high efficiency in cooling by a method wherein a heat conducting disk is capable of movement following a semiconductor element moving back and forth and right and left and, in contact with a heat transfer block, capable of movement up and down. CONSTITUTION:In a cooling device equipped with a heat transfer block 1 using a coolant and a heat conducting disk 3 which is in contact with both a semiconductor element 11 and heat transfer block 1, the heat conducting disk 3 is capable of movement in the wake of the semiconductor element 11 capable of inclination back and forth and right and left, and is capable of movement up and down in contact with the heat transfer block 1. In this way, the scattering of vertical movements of the semiconductor element 11 may be converted into a lateral scattering for the simplification of the structure between the cooling section and the semiconductor element 11. The distance may be shortened between the cooling section and the semiconductor element 11 for a decrease in thermal resistance.

The air is then introduced into the low-concn. adsorption tower 11 through a valve 7A, the remaining impurities are removed therein, and the air is recovered as the produced. The low-concn. adsorption tower 12 and the high-concn. adsorption tower 10 are depressurized by a vacuum pump through a valve 6A to regenerate the adsorbent, the product O2 is introduced into the high-concn. adsorption tower 10 from a valve 8B, and the impurities are desorbed. The effective adsorption amt. of the adsorbent is increased in this way.

摘要： PURPOSE:To recover a gas of high N2 concentration for utilization in conveying coal and in pressurizing a coal-packed container, thereby enabling the realization of smaller equipment for gasification, by installing a unit for holding the gas discharged in the latter period of a desorption stage. CONSTITUTION:The air compressed by a compressor 31 is fed into the top of an adsorption and desorption tower 21, wherein N2, rather than O2, is selectively adsorbed. Air rich in O2 is discharged from the bottom of the tower 21 and blown into a coal burner 25. While the adsorption and desorption tower 21 is in an adsorption stage, desorption is effected in an adsorption and desorption tower 22, and the gas in the tower 22 is discharged into the air from the top. As the discharge of the gas in the tower proceeds, the pressure in the tower decreases so that the desorption of N2 adsorbed by an adsorbent is effected and the N2 concentration of the discharged gas increases. The discharged gas having an N2 concentration of 95% is once stored in a storage tank 23, from which it is sent to a coal-packed container 24, with the feed rate being controlled by a valve 41, to pressurize the container so that the coal is pneumatically conveyed through a coal feeding pipe 28 to a coal burner 25. In a coal gasifier 26, a combustible gas is produced from the coal supplied through the coal burner 25 and a coal gasifying agent.

摘要： PURPOSE:To change the enlarging power without changing an optical element to observe a minute living body in accordance with its properties by moving an enlarging optical element incorporated in an immersed part and a photodetector, which transmits the enlarged optical image of the expanding optical element to the outside, in the direction of the optical axis to change their relative positions by an external control mechanism. CONSTITUTION:An objective lens 21 moved forward and backward by a driver 31 is set on the side of a transmission window 28 to obtain the enlarged optical image of a suspension in a slit 29. This enlarged optical image is transmitted out of an image pickup body 3 by an image fiber 22, which is provided at the rear of the objective lens 21 and can be moved forward and backward by a driver 32, and passes an eyepiece lens 4 and is received by an ITV camera 5, and the image is converted to an electric signal and is projected on a monitor TV 6. Position adjusters 9 and 10 control extents of driving of drivers 31 and 32 in accordance with deviations of new input signals from current position signals, and the enlarging power is arbitrarily changed by this operation without interchanging the objective lens.

摘要： PURPOSE:To enable the production of a large volume of a raw gas for coal gasification with a small apparatus, by reducing the air pressure after formation of a high-concn. nitrogen gas through the use of an adsorbent capable of adsorbing a large amt. of oxygen and pressurized air, thereby forming oxygen- enriched air, and utilizing the air for coal gasification. CONSTITUTION:Air which has been pressurized to such an extent that coal can be transported and the coal packing vessel can be sufficiently pressurized is passed through a plurality of columns packed with an adsorbent in which the equilibrium adsorption amt. of oxygen is larger than that of nitrogen at the same pressure and the same temp., thereby forming a high concn. nitrogen gas. Before the adsorption of oxygen reaches equilibrium, the pressure of air passing through the column is reduced to such an extent that a gasifying agent is sufficiently fed into a coal gasification oven, thereby desorbing the adsorbed oxygen and forming oxygen-enriched air. The above procedures are repeated in a plurality of columns while staggering the operation time, thereby continuously forming a high-concn. nitrogen gas and oxygen-enriched air. Thus, a high- purity nitrogen gas is used for transporting coal and pressurizing the coal packing vessel, while oxygen-enriched air is used as a coal gasifying agent.

摘要： PURPOSE:To remove dust after flocculation and agglomeration by passing the recirculated purified gas through positive and negative ionizers, gasifying the respective generated ions under high-temp. and high-pressure conditions, and injecting the gas into crude gas. CONSTITUTION:Coal and gasifying agent from a raw material system 1 are converted in a reactor 2 under high-temp. and high-pressure conditions into combustible gas of H2, CO, N2, etc., in the dust collector for separating solids contained in a gas. The generated gas contains chair and fine particles. The dust-cong. gas is sent to a cyclone 4 wherein the dust particles are separated from the gas, and then the gas is recycled to the reactor 2. Dust is contained in the gas after passing through the cyclone 4. The gas is branched into a negative ionozer 7 and a positive ionizer 8, and the dust is negatively and positively charged when the ionizers 7 and 8 are connected to both ion generators 9 and 10. The dust is thereby flocculated and agglomerated in a mixer 11, and separated in the succeeding cyclone 13.

摘要： PURPOSE:To advance modification reaction of fuel at low temperature smoothly and to recover a gas having high hydrogen concentration, by inserting plural porous glass tubes of pore structure into a modification catalytic layer in order to transfer modification reaction to a formation system readily. CONSTITUTION:A raw material gas (mixture of hydrocarbon and steam) previously preheated to a given temperature is fed from a raw material feed pipe 1 to a modification catalytic layer 2 and modified into hydrogen as a main component, carbon dioxide and carbon monoxide. Pressure at hollow part of a porous glass hollow module 3 inserted into the modification catalyst is kept lower than pressure of the modification catalytic layer, pore diameter of porous membrane is selected and hydrogen is mainly permeated to a hollow side, separated and recovered. Consequently, a modified gas rich in hydrogen can be recovered through a module collecting pipe 7. A modified gas having low hydrogen concentration not recovered at the module side is fed from a pipe 10 to the outside of furnace and partially used as a fuel for heating a reaction tube so that the gas is introduced as a fuel for a burner to fuel feed pipes 13 and 14.
