Abstract: A miniaturized gas sensor comprised of thick- or thin-film type electrodes, on a non-conductive supportive substrate, and in contact with a solid ionomer electrolyte, for the detection of toxic gases, i.e., carbon monoxide, and other oxidizable or reducible gases and vapors is described. The all-solid planar sensor cell has two or more film type electrodes arranged on a non-conductive planar surface of a supportive substrate. The electrodes are discrete and in intimate contact with the same solid polymer ionomer membrane. The sensor cell contains no liquid electrolyte and is operated in a constant-voltage, potentiostatic or potentiodynamic mode. A high sensitivity to a select gas or vapor is achieved by a novel three-phase contact area design for a sensing electrode which provides contact with the solid ionomer electrolyte, as well as the gas sample via diffusion openings or holes that penetrate through the supportive substrate.

Abstract: A nondestructive evaluating method for aged deterioration in austenitic stainless steel comprises an information obtaining step for previously obtaining a relationship between an applied stress a arid the first ratio Ms/xH* between a saturation magnetization Ms and a pseudo susceptibility xH* based on reference minor hysteresis loops obtained by applying stresses .sigma., respectively, correspondingly to a result of a tensile test for the same kind of material as an evaluation target. In a measuring step, values of the first ratio Ms/xH* are obtained as measured values from measured minor hysteresis loops obtained by measuring the evaluation target.  In an evaluating step, the relationship between the applied stress 6 and the first ratio Ms/xH* is compared with the measured values, thereby evaluating aged deterioration of the evaluation target. The minor loops are obtained by stepwise changing a magnetic field amplitude Ha within a range of a magnetic field intensity lower than a saturation magnetization.

Abstract: A phased array antenna system with adjustable electrical tilt includes an array (62) of antenna elements 621, to 6210. It has a splitter (44) dividing a radio frequency (RF) carrier signal into two signals between which a phase shifter (46) introduces a variable phase shift. Further splitters (52) and (54) divide the relatively phase shifted signals into two sets of five signals. Four of each of the sets of five signals are vectorially combined in a network of 180 degree hybrid couplers 601, to 604. This provides vector sum and difference components which together with the fifth members of the sets are fed to respective fixed phase shifters (56, 58) and 641, to 6410. The phase shifters 641, to 6410 provide signals which are appropriately phased for use as phased array drive signals for respective antenna elements 621, to 6210. Adjustment of the single phase shift provided by the variable phase shifter (46) changes the angle of electrical tilt of the entire antenna array (62).
