摘要： A thickness detecting sensor can widely set a dynamic range for detecting the thickness of a medium, and exactly detect the thickness of the medium even when the dynamic range is widely set in this way. Therefore, the thickness detecting sensor has a fixing electrode and a movable electrode arranged so as to be opposed to each other, a plunger for changing the gap between the electrodes by coming in contact with the medium, and a CR oscillating circuit and an FV converting circuit for converting electrostatic capacity stored between the electrodes into an electric signal for detecting the thickness of the medium. The rear end portion of the plunger comes in contact with the electrode face of the gap side of the movable electrode. The movable electrode is displaced in the direction separated from the fixing electrode correspondingly to the thickness of the medium.

摘要： A flow velocity measuring device is able to conduct a fluid to a sensor element after removal of dust and dirt contained in the fluid to accurately measure the flow velocity of the fluid even when the fluid is low in flow velocity and the device is mounted in any direction. A flow passage is formed by internal spaces, which have curved wall surfaces, introduction passages connected to the internal spaces at one ends of the wall surfaces tangentially to the wall surfaces, discharge passages connected to the internal spaces at the other ends of the wall surfaces tangentially to the wall surfaces, and branch discharge passages connected to the internal spaces at substantially right angle to a direction, in which the wall surfaces are curved, and a sensor element is arranged in the branch passage or a flow passage connected to the branch passage.

摘要： An input device, which is small-sized and inexpensive in spite of being simple in construction and thin, comprises at least one primary electrode and a plurality of secondary electrodes, both electrodes being formed in the same plane. A position of a dielectric is identified on the basis of differences in electrostatic capacity between the primary electrode and the secondary electrodes, which electrostatic capacity is changed by the dielectric positioned on a surface side of the both electrodes.
