Abstract: PROBLEM TO BE SOLVED: To improve treatment efficiency by specifying adsorption property and adsorption condition of zeolite used as an adsorbent in separating nitrogen with an adsorbent from a gas mixture containing nitrogen and at least one gas having a lower polarity than nitrogen by utilizing gas difference adsorption technique. SOLUTION: In the so called PSA method using adsorption difference property on a zeolite molecular sieve in order to separate gases in the air into nitrogen, oxygen and further argon, nitrogen is desorbed at a low pressure to regenerate adsorption property of zeolite after having adsorbed nitrogen at high pressure to enrich the gas phase with oxygen. In this process the zeolite which gives the nitrogen adsorption isothermal curve at 20 deg.C having a curvature characterized by a parameter C defined by the formula (in the formula q(P1 ), q(P2 ) are amounts of nitrogen respectively adsorbed at pressures P1 , P2 ) is used as the adsorbent. The process is operated at least at 40 deg.C and parameter C is set to at least 2.5.

Abstract: PURPOSE:To manufacture a uniform carbon fiber-reinforced pipe, by inserting a substrate having desired form into a hollow heater, heating the substrate from outside, and supplying gaseous hydrocarbons to the center hole of the substrate, thereby depositing the thermally cracked carbon to the circumference of the substrate. CONSTITUTION:The above substrate, especially preferably a woven cloth of spun short carbon fibers, is inserted into a hollow heater. The hollow heater is a conventional porcelain tube for electrical furnace and made mainly of alumina, silica, etc. The substrate is heated from outside by heating the hollow heater, and gaseous hydrocarbons are supplied continuously to the hollow part of the substrate which is being in contact with the inner surface of the hollow heater. The supply of the hydrocarbon gas results in the temperature gradient from the inner surface to the outer surface of the substrate, and the carbon produced by the thermal cracking of the hydrocabons is deposited in the substrate successively from the outer layer having higher temperature. As a result, a high-performance carbon fiber-reinforced carbon pipe containing thermally cracked carbon deposited uniformly up to the inner surface of the substrate can be manufactured by this process.

Abstract: PURPOSE:To calculate a density of a sample with a calibration curve presented by a polynomi al approximation by making a calibration curve of a linear approximation determined from an actually measured value of a standard sample as first approximate calibration curve to determine a first approximate value of the density of the sample. CONSTITUTION:A plurality of standard samples are set for a measuring section 1 made up of a light source L, a sample cell C and an absorbance measuring means D. A control section 2 is set to a calibration curve generation mode and a measuring data is loaded sequentially to generate a main calibration curve by a polynomial approximation. Then, a first approxi mate calibration curve is prepared as linear formula connecting measured values of standard samples of minimum and maximum densities, respectively. Then, a sample to be measured is set on the measuring section 1, the control section 2 is set to a measuring mode and a measurement is performed to calculate a first approximate density with a measured value put into a expression of a first approximate calibration curve. Then, when a sequential approximate solution of a main calibration curve expression is calculated by a Newton- Raphson method with the calculated value as initial value, a density of the sample to be measured can be determined. This allows a quick convergence of a sequential approximate calculation thereby eliminating a possibility of reaching an unrealistic calculated value.

Abstract: PROBLEM TO BE SOLVED: To enable adjusting of gain inclination, by controlling the temperature of a light filter which is optically connected between a light amplifier and a pumping light source, and having wavelength selectivity in dependence on temperature in accordance with a control signal. SOLUTION: An optional filter 28 is optically connected between a light amplification medium 24 and a pumping light source 26, and the pump light P outputted from the pumping light source 26 passes through the optical filter 28 and it is fed to the light amplification medium 24. The optical filter 28 has the wavelength selectivity in dependence on temperature. A control unit 30 controls the temperature of the optical filter 28 in accordance with the received control signal. When the temperature of the optical filter 28 changes, the wavelength selectivity of the optical filter 28 changes, and the center wavelength of the pumping light P, which is fed to the light amplification medium 24, changes. When the center wavelength of the pumping light P changes, the gain wavelength characteristics generated on the light amplification medium 24 changes.  Accordingly, the gain inclination generating in the light amplification medium 24 can be controlled based on the control signal CS.
