<p>PURPOSE:To obtain a new sensor raw material using no wood by mixing and sintering the powder of metals selected form the fourth family B, the first family B, and the eigher family, in the periodic table, a ceramics radiating an extreme infrared ray, and a ceramics having a piezoelectric or a thermoelectric function. CONSTITUTION:This raw material includs one or two sorts of elements of the fourth family B, the first family B, and the eighth family, in the periodic table, a ceramics to radiate an extreme infrared ray, and a ceramics having a piezoelectric or a thermoelectric function, as its main components, and it is made by mixing and sintering the powders of the comonents. By mixing and sintering the powders of metals selected from the fourth family B, the first family B, and the eighth family in the periodic table, the ceramics radiating the extreme infrared ray, and the ceramics having the piezoelectric or the thermoelectric function, a new sensor raw material without using a wood is obtained. As the elements of the iv family B in the periodic table, C, Si, Ge, and the like; as the elements of the i family B, Cu, Ag, and Au; and as the elements of the viii family, Ir, Pt, and Pd are avairable respectively. As the ceramics radiating the extreme infrared ray, SiC, C, mullite, and the like, and as the ceramics having the piezoelectric or the thermoelectric function, tourmaline and the like are avairable respectively. By using an element which consists of the mixtur and the sintered body of those powders to form a receiver sensor 4 or a transmitter sensor 2, it is not necessary to contant to the leaves of trees directly. And when the materials of the transmitter and the receiver are loaded on a transmitter table 3 and a receiver table 5, it can be decided whether two materials are the same or not by the lamp display of CSR 7.</p> |
