摘要： A capacitive gas sensor in which a second electrode layer made of a nano-carbon material entangled to be three-dimensionally reticulated and a gas-sensitive film are not separated from each other. A capacitive gas sensor includes a substrate; a first electrode layer formed on the substrate; a gas-sensitive film formed on the first electrode layer and having air permeability; and a second electrode layer formed on the gas-sensitive film to be opposed to the first electrode layer and made of a nano-carbon material entangled to be three-dimensionally reticulated. The capacitive gas sensor also includes a reinforcing resin layer having air permeability and disposed at least on the second electrode layer.

摘要： A force sensor unit having a simple structure to allow ready assembling and easy downsizing of the force sensor unit. The force sensor unit includes a cylindrical body, a substrate that blocks one end of the cylindrical body, a force sensor that is supported on the substrate, and a force transmission mechanism that is disposed in an internal space of the cylindrical body to transmit a force to the force sensor. The force transmission mechanism includes a contact member, a coil spring, and an operated member. These members are arranged in order in the internal space of the cylindrical body, and are not adhered to nor engaged with each other. The members except the substrate are simply fitted loosely in the internal space of the cylindrical body, thereby facilitating assembling of the force sensor unit and enabling downsizing of the force sensor unit.

摘要： A semiconductor pressure sensor device in which the shape or the structure of a connector portion can be easily changed and which has high waterproof performance. A terminal housing and a second case are engaged with each other via an engagement structure. The terminal housing and a first case are fitted with each other via a fitting structure. Thus, the first case and the second case are fixed to each other via the terminal housing. The first case is fitted in the second case. Then, the terminal housing is fitted with the first case, and the terminal housing is engaged with the second case substantially at the same time. Through such simple process, an opening portion of the first case is covered and a connector portion configured to enable external terminals to be connected to ends, located on one side, of a plurality of lead terminals is formed.

摘要： A pressure sensor device with good temperature characteristics. An auxiliary fluid introduction path is provided in a bottom wall portion of a first case to introduce a fluid to the vicinity of a recessed portion of the bottom wall portion where an integrated circuit with a large change in temperature characteristics is mounted such that the temperature of the integrated circuit becomes the same as or close to the temperature of the fluid.

摘要： A piezoelectric sounding element includes a diaphragm made of metal and a piezoelectric element provided on at least one surface of the diaphragm. A non-fixed portion of the diaphragm includes the pair of long sides facing each other, a pair of short sides, shorter than the long sides, that face each other, and a pair of recesses, provided in the pair of long sides, that protrude so as to approach each other. The piezoelectric element is provided in a region between the pair of recesses of the diaphragm and the contour shapes of the non-fixed portion of the diaphragm and the piezoelectric element are defined so as to be symmetric with respect to a first imaginary line that bisects the pair of short sides and symmetric with respect to a second imaginary line that bisects the pair of long sides.

摘要： A force detector capable of preventing short-circuit fault between electrodes and allowing for downsizing. A prescribed region encompasses a projection region defined by projecting a deformation region of a force sensor element, which is deformed when a force transmission member applies a force to the force sensor element, onto a base substrate. A plurality of terminals are provided by four soldering land electrodes formed, respectively, at four corners of the base substrate. The soldering land electrodes are shaped such that a portion of each soldering land electrode is located within the projection region to form a soldering portion.
