    摘要： First to third frames are formed by etching to penetrate a silicon substrate on the substrate. A plurality of thin cantilevered beams are formed in different lengths by cutting by etching the substrate in the frames; the beams formed in the first frame are formed perpendicular to the surface of the substrate to bend only in the X-axis direction, parallel to the surface of the substrate; the beams formed in the second frame are formed perpendicular to the surface of the substrate to bend only in the Y-axis direction, parallel to the surface of the substrate; and the beams formed in the third frame are formed to bend only in the Z-axis direction, perpendicular to the surface of the substrate. Masses are formed at the free ends of the beams, and piezo resistance layers are formed at the fixed ends. Signals generated from the piezo resistance layers by an integrated circuit are supplied to the regions, different from the regions formed of the first to third frames, of the substrate to form a signal processor for generating acceleration detection signals.

    摘要： An apparatus for optically detecting the attachment state of extraneous matters to a translucent shield member. The optically detecting apparatus comprises a light-emitting unit having a plurality of light-emitting elements each emitting a light ray toward the translucent shield member, a photoelectric transducer unit having a plurality of transducer elements each receiving each of the light rays reflected on the translucent shield member, and a data processing unit coupled to the transducer unit. The transducer unit generates detection signals corresponding to the quantities of the received light rays and the data processing unit successively compares the level of each of the detection signals with a predetermined level to produce binary signals in accordance with the results of the comparison so that a binary signal pattern is defined at the respective transducer elements. The data processing unit determines the attachment state of the extraneous matters to the translucent shield member by comparing the defined binary signal pattern with a reference pattern.
