摘要： A sensing section has a support member having a recess formed thereon, and a floating region disposed on the support member and formed by a recess. The sensing section has a slit through which the medium to be measured passes is formed in a portion exposed to the medium to be measured. A protective film made of a material having higher liquid repellency than that of the sensing section or more lyophilic than the sensing section is provided in the slit while maintaining a state in which the medium to be measured passes.

摘要： A system is for detecting a location of a touch input on a surface of a propagating medium. The system includes a transmitter coupled to the propagating medium and configured to emit a signal. The signal has been allowed to propagate through the propagating medium and the location of the touch input on the surface of the propagating medium is detected at least in part by detecting an effect of the touch input on the signal that has been allowed to propagate through the propagating medium. The system includes a piezoresistive sensor coupled to the propagating medium. The piezoresistive sensor is configured to at least detect a force, pressure, or applied strain of the touch input on the propagating medium.

摘要： A pressure gauge includes: an outer container defining an outer chamber set to a reference pressure (Pr); an inner container disposed in the outer container; and a tube setting the inside of a first inner chamber of the inner container to a measurement pressure (Px). The inner container includes: a cylindrical rigid wall portion; first and second pressure receiving plates that displace due to a differential pressure between the reference pressure and the measurement pressure; a bellows partitioning the inner container into the first inner chamber and a second inner chamber; and a pressure detection element disposed in the second inner chamber and detecting the measurement pressure based on the displacements of the first and the second pressure receiving plates. The outer chamber and the second inner chamber are set to the reference pressure of a high vacuum that is lower than a lower limit of the measurement pressure.
