    摘要： A sensor material for measuring physical parameters capable of configuring a sensor capable of directly measuring a high value of physical parameters such as high stress or high pressure without employing a pressure resistance container. The sensor material for measuring static and dynamic physical parameters includes a matrix made of an electrically insulating ceramic material, and piezoresistance materials which are dispersed in the matrix so as to be electrically continuous to each other.

    摘要： A pressure detection device for detecting an increase of pressure acting thereon includes an electrically conductive device housing which has an accommodation bore extending inward from one end of the device housing and a slide bare extending between the accommodation bore and the other end of the device housing. A piston is slidably disposed within the slide bore and adopted to receive a pressure, and a terminal serving as one electric contact is fixed to the accommodation bore via an electrical insulator. A disk spring serving as the other electric contact deforms due to a pressing force of the piston and coming in contact with the terminal. The pressure detection device further comprises an electro-functional member attached to either the terminal or the disk spring in which the electro-functional member is changeable its electric resistance due to an impressed pressing force acting thereon. Further, at least one of a notch and a chamfer is provided on the electro-functional member for changing its electric resistance characteristic.

    摘要： Provided is a low-cost, highly responsive, and highly durable thermistor material for use in a reducing atmosphere, with which temperature can be measured even under a reducing atmosphere such as a hydrogen gas atmosphere or in a vacuum without the thermistor material being sealed with a glass seal or a metal tube. The thermistor material includes a matrix material made of an insulating ceramic and a non-oxide conductive material, and conductive particles are dispersed around the matrix material to thereby form a conductive path. The conductive particles are preferably dispersed in a network structure around the matrix material. Further, the conductive particles are preferably dispersed discontinuously around the matrix material.
