    Abstract: A vibration gyroscope includes: a mass part supported to be displaceable in a first direction and a second direction; an exciter vibrating the mass part in the first direction; and a detector detecting a displacement amount of the mass part in the second direction. The first direction and the second direction are orthogonal to each other. A resonance frequency of the mass part in the first direction coincides with a resonance frequency of the mass part in the second direction. A Q-factor of vibration of the mass part in the second direction is smaller than a Q-factor of vibration of the mass part in the first direction.

  • Patent number: 8698315
    Abstract: When forming a trench of a narrow width in a thick semiconductor layer, a trench can be formed without the occurrence of semiconductor residue. In this Specification, a semiconductor device in which a trench is formed in a semiconductor layer is disclosed. In the semiconductor layer of the semiconductor device, a compensation pattern which compensates for sudden changes in the width of the trench is formed at a place at which the width of the trench changes suddenly. In the semiconductor layer of the above-described semiconductor device, since a compensation pattern is formed at a place at which the trench width changes suddenly, in the case where forming the trench using a deep RIE method, the occurrence of steep inclined portions arising from semiconductor residue can be prevented. Consequently, when forming a trench of a narrow width in a thick semiconductor layer, the occurrence of semiconductor residue can be prevented.

  • Patent number: 6865953
    Abstract: A pressure sensor has a housing having a first block and a second block provided therein. A force to be measured applies upon a upper face of the first block. An upper face of the second block makes contact with a base face of the first block. Piezoresistive elements are formed within the base face of the first block. The resistance values of these piezoresistive elements change as contacting pressure between the first block and the second block changes. A first electrode is formed on an upper face of the first block. A second electrode is formed on a base face of the second block. Electrical characteristics between the first electrode and the second electrode change following change in the contacting pressure between the first block and the second block.
