  • Patent number: 8601872
    Abstract: A vibrating gyroscope according to this invention includes a ring-shaped vibrating body 11 having a uniform plane, a leg portion 15 flexibly supporting the ring-shaped vibrating body and having a fixed end, a fixed potential electrode 16, and a plurality of electrodes 13a, 13b, . . . , 13h formed on the plane with a piezoelectric film sandwiched between an upper-layer metallic film and a lower-layer metallic film in a thickness direction thereof. In this case, in a representative example shown in FIG. 1, when one of driving electrodes 13a for exciting a primary vibration of the ring-shaped vibrating body 11 in a vibration mode of cos N? is set as a reference driving electrode, the plurality of remaining electrodes 13b, . . . , 13h are disposed at specific positions. Such disposition allows this vibrating gyroscope to detect a uniaxial to triaxial angular velocity by adopting a secondary vibration detector inclusive of an out-of-plane vibration mode.

  • Publication number: 20100228149
    Abstract: A sensor device has a needle-integrated type sensor element which is detachably mounted therein and which has a sensor chip, a lancet needle fixed to an end portion of the sensor chip, and a flow path forming element provided compressibly and restorably at the end portion of the sensor chip, to which the lancet needle is fixed. The sensor device includes a puncture mechanism (a drive spring) configured to cause the sensor element to puncture a target, and a pressing mechanism (a pressure spring) configured to urge the sensor element to the extent that the sensor element is prevented from being detached from the target by a restoring force of the flow path forming element after the target is punctured.

  • Publication number: 20100069792
    Abstract: A biosensor cartridge capable of performing puncturing in an exact position, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When tip portion 11a of biosensor chip body 11 is pushed against a subject M, elastic body 20 protruding from a tip portion 11a of biosensor chip body 11 is compressed, and puncturing tool 12 for puncturing protrudes. Thus, the subject M can be punctured. Additionally, if a pushing force is weakened, puncturing tool 12 is extracted from the subject M by the restoring force of elastic body 20, and the sample R flows out of the puncture hole. Additionally, cover member 19 is provided around biosensor chip body 11. Thus, when puncturing is performed by thin plate-shaped biosensor cartridge 10, biosensor chip body 11 can be prevented from deforming, and puncturing can be accurately performed in a desired puncturing position.

  • Publication number: 20100004559
    Abstract: A biosensor cartridge capable of making the collected amount of a sample required for measurement into a small quantity to reduce a user's burden, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When one end portion of biosensor chip is pushed against subject, elastic body is compressed, and puncturing tool can protrude and perform puncturing. Additionally, if a pushing force is weakened, puncturing tool is extracted from subject by the restoring force of elastic body, and blood (sample) flows out of the puncture hole. In this case, since the puncture hole, and sample collection opening provided at biosensor chip are contained in enclosed half-open space formed by elastic body, even a small amount of blood (sample) can also be easily collected.

  • Publication number: 20090299225
    Abstract: There is provided a biosensor chip where the collecting amount necessary for the measurement is made small whereby burden of a user is reduced and, at the same time, a sample at a puncture opening is able to be easily collected and measured without an operation of making the sample collection opening nearer the puncture opening. When an end of a main body chip is pushed onto a test body, an elastic body installed at an end of the main body chip is compressed and a device for puncture is produced whereby the test body is able to be punctured. When the pushing force is made weak, the device for puncture is pulled out from the test body due to resilience of the elastic body and a sample is flown out from the puncture opening.
