  • Patent number: 9167352
    Abstract: A microphone has a base substrate having a main surface, an acoustic sensor mounted on the main surface, and a circuit element that processes a signal output from the acoustic sensor. The acoustic sensor has a sensor substrate having a first surface opposed to the base substrate, a second surface on a side opposite to the first surface, and a cavity formed while piercing the sensor substrate from the first surface to the second surface, and a movable electrode that covers the cavity from the second surface side. A through-hole is formed in the base substrate while piercing the base substrate in a thickness direction to communicate with the cavity. The through-hole overlaps the sensor substrate when viewed in the thickness direction of the base substrate.

  • Patent number: 9126823
    Abstract: A microphone has a base substrate comprising a main surface, an acoustic sensor mounted on the main surface, and a circuit element stacked on the acoustic sensor. A hollow space is formed between the acoustic sensor and the circuit element. The acoustic sensor has a sensor substrate having a first surface opposed to the base substrate, a second surface on a side opposite to the first surface, and a cavity formed while recessed with respect to the second surface, and a movable electrode that covers the cavity from the second surface side. A through-hole is formed in the base substrate while piercing the base substrate in a thickness direction. A communication hole is formed in the sensor substrate while piercing the sensor substrate from the first surface to the second surface. The communication hole causes the through-hole and the hollow space to communicate with each other.

  • Patent number: 8096976
    Abstract: A valve body is formed from an elastic member in the form of an elliptic or circular film (disk shape) having an upper face and a lower face. The valve body has an opening and closing section which is opened and closed in response to insertion and pulling out of a dilator and is formed from a first slit, a second slit, a second concave portion and two third concave portions. A pair of ribs and six projections are formed on the lower face side of the valve body. The ribs are disposed in opposing relationship to each other with the second slit interposed therebetween and extend along the lower face. Further, the projections are disposed such that they are positioned on the inner side of the ribs and are opposed to each other with the second slit interposed therebetween.
