ジャーナル フリーTransient response curves for aromas from several kinds of alcohol such as Fruit Liquor(8%), Wine(14%), Japanese Sake(15%) and Whisky(43%) are observed using quartz-crystal-resonator gas sensor coated with synthetic-resin-film (acrylic resin, alkyd resin or urethane resin).
The pattern recognition analysis using principal component analysis or neural network analysis is carried out using four parameters which characterize the transient response curves. The recognition probability of neural network for four kinds of alcohol is 100% for 20 trials.抄録全体を表示PDF形式でダウンロード (856K) -

ジャーナル フリーThe taste of beer was measured using a taste sensing system with eight kinds of lipid membrane. The output from the sensor has high discriminating power and high correlation with taste substances in beer and sensory test by human. The estimation of the concentration of taste substances by multiple regression analysis was fairly well. The taste sensor also well estimated the result of sensory test of many keywords concerning beer taste.抄録全体を表示PDF形式でダウンロード (1220K) -

ジャーナル フリーThis paper describes ultrasonic transmission techniques for sensor signals transmitted through water-filled pilot pipes for underground microtunneling systems. Underwater ultrasonic waves are expected to be used for transmitting the orientation and location signals of a remote controlled machine. We have investigated the relationship between ultrasonic transmission loss and frequency for propagation distance in water-filled pipes. Digital signals can be transmitted at 100 bps for more than 50m distance in 80-mm-diameter steel pipes by using underwater ultrasonic pulse waves over 300kHz. A compact prototype ultrasonic transmitter and receiver are developed, making it possible to transmit and receive digital signals by processing their signal waveforms through flowing water in the pilot pipes. Field trials indicate a range of signal transmission of pitching angle over 40-m distance for an actual compact microtunneling system.抄録全体を表示PDF形式でダウンロード (3231K) -

ジャーナル フリーWe have developed a multichannel taste sensor with artifical lipid membranes and have applied it to quantification of taste of green tea. We used multiple regression analysis and found high correlations of outputs of the taste sensor with the results of sensory test (taste, flavor and color) and chemical analyses (amino acids and tannin that are main taste substances in green tea). It is concluded that the taste sensor has a potential for quantification of taste of green tea. The taste sensor responds not only to amino acids and tannin, but also to many other taste substances, and hence it contains much more taste information than conventional chemical analyses.抄録全体を表示PDF形式でダウンロード (1921K) -

ジャーナル フリーGas sensors for detecting SF5 decomposition products are being actively pursued as low cost instrumentation for detecting and locating faults in GIS. We developed a potentiometric solid state ionic sensor using high ionic conductive solid. The sensor responded to the changes in HF concentration ranging from 1 to 1000wt.ppm in SF6 gas at 1atm. The electromotive force of the sensor increased linearly with an increase in the logarithm of PHF following Nernst equation. The slope of the line suggested that the number of charge transfer of the electrode reaction is unity.抄録全体を表示PDF形式でダウンロード (1983K) -
