In order to provide a pressure-swing-adsorption oxygen production process which can maintain the product recovery at a high level while enhancing the oxygen productivity and reducing the unit power consumption, a pressure recovery step is carried out in which communication is provided between an outlet end of an adsorption column which has completed an adsorption step and an outlet end of an adsorption column which has completed a regeneration step, and in which gas remaining in the adsorption column which has completed the adsorption step is collected within the adsorption column which has completed the regeneration step; and simultaneously with the pressure recovery step, a gas mixture which has approximately the same composition as feed gas mixture is introduced into at least one of the adsorption column which has completed the adsorption step and the adsorption column which has completed the regeneration step through the inlet end thereof.

Nodes and paths for connecting the nodes are used to form a model of at least one logic network. Next, all paths for connecting nodes in the logic network are traced, and the nodes and connecting path segments are sensitized and justified. The sensitizing patterns, when generating test patterns for a sequential circuit wherein the output is a function of a time sequence of inputs, may include a time sequence of sensitizing or input patterns for testing a single path through the network.

This gas purifying process removes trace constituents from a mixed gas that includes a rare gas and nitrogen as main components, and at least one from among hydrogen, nitrogen and hydrogen reaction products, and water vapor as the trace constituent. This process sequentially carries out an adsorbing step for removing water vapor and nitrogen and hydrogen reaction products; a hydrogen oxidation step for converting the hydrogen into water vapor by means of a hydrogen oxidation catalytic reaction in the presence of oxygen; and a drying step for removing water vapor generated in the hydrogen oxidation step. When nitrogen oxides are included as a trace constituent, then a denitration step is carried out prior to the adsorbing step, to convert nitrogen oxides into nitrogen and water vapor by means of a catalytic denitration reaction in the presence of a reducing substance.

The present invention is directed to provide an underwater detection system which can determine frequency components contained in echoes arriving from all azimuthal directions at high speed and enhance target discriminating capabilities by presenting such frequency components.The underwater detection system rotates a pair of ultrasonic receiving beams having a fixed phase angle difference, measures phase differences between two signals picked up by both ultrasonic receiving beams, determines carrier frequencies contained in target echoes from the phase differences, derives magnitudes and directions of moving velocities of targets from the carrier frequencies, and displays such target data in different colors. Furthermore, it provides such information as over-the-ground velocities of targets themselves upon compensating target velocity data with ship velocity data.

A plurality of first flip-flop circuits are provided having outputs connected respectively to inputs of a logic circuit. During a test mode, scan data is first loaded into the flip-flop circuits to activate desired logical paths in the logic circuit and subsequently a pulse is scanned across the first flip-flop circuits to cause successive reversals to occur in the stored scan data. As a result, test signals can propagate through the activated logical paths. Connected to the outputs of the logic circuit are a plurality of second flip-flop circuits which are configured into a linear feedback shift register during the test mode to enable a test circuit to observe its serial output to determine the dynamic performance of the logic circuit.

A flip-flop circuit receives a portion of a multiple bit output from a combinational logic circuit to be tested, and feeds back a plurality of bits to comprise a portion of the multiple bit input to the combinational logic circuit. The flip-flop circuit includes a plurality of master and slave flip-flops with the master flip-flops being operable in parallel to receive the output from the combinational logic circuit or in series as a shift register, and the slave flip-flops being operable either in parallel to receive outputs from the master flip-flops or in series as a shift register. The occurrence of a fault in a combinational logic circuit can be determined by examining the contents of either the master or slave flip-flops at a particular clock cycle.

A LEX signal tracking method of continuously tracking a LEX signal is provided. The LEX signal broadcast from a Quasi-Zenith Satellite is demodulated. A weekend approach notification signal Snear is generated based on a time within a week obtained from the demodulated LEX signal. A state of a Long code, which is generated when a code correlation processing is performed, is analyzed. If the analyzed code state is in agreement with a stored 997425th code state, a pulse signal dplus is generated. If the generation of the pulse signal dplus is immediately after the detection of the weekend approach notification signal Snear, the Long code is reset to an initial state.
