    摘要: A semiconductor mechanical sensor having a new structure in which a S/N ratio is improved. In the central portion of a silicon substrate 1, a recess portion 2 is formed which includes a beam structure. A weight is formed at the tip of the beam, and in the bottom surface of the weight in the bottom surface of the recess portion 2 facing the same, an electrode 5 is formed. An alternating current electric power is applied between the weight portion 4 and the electrode 5 so that static electricity is created and the weight is excited by the static electricity. In an axial direction which is perpendicular to the direction of the excitation of the weight, an electrode 6 is disposed to face one surface of the weight and a wall surface of the substrate which faces the same. A change in a capacitance between the facing electrodes is electrically detected, and therefore, a change in a physical force acting in the same direction is detected.

    摘要: When a compressed air is led into a reference pressure chamber along with a boundary between a resin housing and a terminal, such compressed air may cause a wire breaking. A barrier wall for blocking the compressed air from penetrating toward the wire is disposed. The reference pressure chamber is divided into a main chamber and a subchamber by the barrier wall. Since the barrier wall blocks the compressed air, the compressed air can not reach a silicon gel in the main chamber. Therefore, the wire breaking caused by the compressed air when connecting a connector therewith can be precluded.

    摘要: A first end of each hollow stem includes a diaphragm and a strain gauge, and a second end of each stem includes an opening. A housing includes a plurality of stem receiving through holes, each of which receives the corresponding stem. An O-ring is arranged in each through hole such that the O-ring is placed adjacent an end surface of the second end of the stem, which is axially inwardly spaced from a surface of the side of the housing. When the stems and the housing are integrally installed over the device under test, each O-ring seals between the end surface of the second end of the corresponding stem and the device under test.
