Abstract: A stacked mounting structure includes a first substrate, a second substrate, and an intermediate substrate which has a space accommodating therein components to be mounted. A first contact (connecting) terminal and a second contact (connecting) terminal are formed on the first substrate and the second substrate, and have a wire which is formed on a side surface of the intermediate substrate. By formation of the intermediate substrate to be on an inner side than an edge surface of the substrates, a part of the two contact terminals respectively are exposed. One end of the wire is connected to an exposed portion of the first contact terminal, and the other end of the wire is connected to an exposed portion of the second contact terminal.

Abstract: A capacitive micromachined ultrasonic transducer (cMUT) at least including a silicon substrate, a bottom electrode mounted onto the silicon substrate, a upper electrode mounted facing the bottom electrode and apart therefrom by a predetermined cavity, and a membrane supporting the upper electrode, wherein a part of the aforementioned cMUT is charged.

Abstract: An ion conducting high-polymer member is formed by an ion containing polymer, and has a circular arc shape. An chord length of the ion conducting high-polymer member is changed. Due to the change in the chord length of the ion conducting high-polymer member, there is change in a relative position of a driving shaft which is coupled with the ion conducting high-polymer member, with respect to a rotating shaft. Due to the change in the relative position of the driving shaft, a circular ring shaped peripheral section is displaced, and due to a rotation of a diaphragm member around the rotating shaft as a center, a part of an aperture is shielded by the circular ring shaped peripheral section, and a diameter of the aperture is changed.

Abstract: An impact drive actuator comprises a vibrating base plate configured to be slightly displaced in a reciprocating manner by a vibrator in first and second directions, a first slider disposed on the vibrating base plate, a first electrode formed on the vibrating base plate, a second electrode so formed on the first slider as to face the first electrode through an insulation film, and a potential difference generator configured to generate a potential difference between the first and second electrodes to allow a first electrostatic attractive force to act between the vibrating base plate and first slider. When the vibrator reciprocates the vibrating base plate, the time needed to displace the vibrating base plate in the first direction is different from that in the second direction. The first slider is displaced relative to the vibrating base plate in the direction where the time needed for displacement is larger.
