  • Patent number: 8794069
    Abstract: An angular velocity sensor includes a vibrator, a support substrate, an anchor section, a connection beam section, a driving section, and a detection section. The vibrator includes an inner vibrator and an outer vibrator, which vibrate in opposite circumferential directions when driven by the driving section. The connection beam section couples the vibrator to the anchor section, and is elastic in a z-direction and a circumferential direction. The connection beam section includes first connection beams, each of which is coupled to the outer vibrator at one end and is coupled to the inner vibrator at the other end, and second connection beams, each of which is coupled to a vibration node of a corresponding first connection beam at one end and is coupled to the anchor section at the other end.

  • Publication number: 20140157902
    Abstract: An ultrasonic sensor device includes a substrate, a piezoelectric vibrator, and a Q-factor adjuster. The piezoelectric vibrator includes a pair of detection electrodes that face each other in a thickness direction of the substrate and a piezoelectric body interposed between the electrodes. The piezoelectric vibrator provides a membrane structure which is formed on a surface of the substrate and has rigidity lower than that of a remaining portion of the substrate. An ultrasonic wave is transmitted by the piezoelectric vibrator, and its reflected wave is received by the same piezoelectric vibrator. The Q-factor adjuster adjusts a Q-factor of the piezoelectric vibrator so that the Q-factor can be larger during a transmission period where the piezoelectric vibrator transmits the ultrasonic wave than during a reception period where the piezoelectric vibrator receives the ultrasonic wave.

  • Patent number: 8578761
    Abstract: A concentration sensor device includes a sensor unit, a substrate, and a sedimentation limit unit. The sensor unit detects a concentration of a specific component contained in liquid. The substrate has a face to which the sensor unit is arranged. The sedimentation limit unit is integrally arranged with the sensor unit or arranged at an upstream side of the sensor unit in a flowing direction of the liquid. The sedimentation limit unit is configured to prevent sedimentation of a foreign object on the sensor unit. The sedimentation limit unit includes a piezoelectric element to vibrate when electricity is supplied so as to promote the foreign object to be separated from the sensor unit. The substrate has a recess recessed in a thickness direction of the substrate.

  • Patent number: 8413507
    Abstract: A semiconductor dynamic quantity sensor has a substrate including a semiconductor substrate, an insulation layer on a main surface of the semiconductor substrate, and a semiconductor layer on the insulation layer. The main surface has a projection that is trapezoidal or triangular in cross section. The semiconductor layer is divided by a through hole into a movable portion. A tip of the projection is located directly below the movable portion and spaced from the movable portion by a predetermined distance in a thickness direction of the substrate. A width of the tip of the projection is less than a width of the movable portion in a planar direction of the substrate. The distance between the tip of the projection and the movable portion is equal to a thickness of the insulation layer.

  • Patent number: 8332159
    Abstract: A method of enhancing the efficacy of a monoclonal antibody preparation wherein antigens from patients are tested for their reactivity with the antibody. An amino acid sequence of an expressed protein is deuced from a nucleotide sequence determined by isolation and analysis of a target molecule gene in a biopsy from a patient. This is compared with the previously determined amino acid sequence recognized by the monoclonal antibody preparation in order to assess the fitness of patients for administration of the monoclonal antibody preparation.

  • Patent number: 8210040
    Abstract: An oscillating angular speed sensor includes a detector, a driving portion, and a separating portion. When an angular speed is generated while the detector is driven to oscillate by the driving portion, Coriolis force is applied to the detector. Therefore, the angular speed is detected based on a capacitance variation in accordance with a variation of an interval between a movable electrode and a fixed electrode of the detector. The separating portion is distanced from the detector and the driving portion, and is configured to separate a first space accommodating the detector and a second space accommodating the driving portion.
