    摘要： A surface acoustic wave filter which comprises: a substrate of piezoelectric material; a multistrip coupler for changing the track of a signal comprising a plurality of parallel conductive strips; at least two transducers disposed on one side of the multistrip coupler; at least another two transducers disposed on the other side of the multistrip coupler. The latter two transducers facing the former two transducers. One pair of the transducers which face each other through the multistrip coupler constitutes input transducers while the other pair of the transducers constitutes output transducers.

    摘要： A position detector having a magnetic sensor for measuring linear or angular displacement, or detecting a position of a body without contact thereto. The detector has a closed circuit including magnets and yokes. The magnetic leakage flux which emanates from the inside surfaces of the yokes is utilized to detect the position of the body. The magnetic sensor is transferred along the inside surfaces of the yokes by a transferring circuit, which senses the magnetic field intensity of the leakage flux distributed thereon. This enables the detector to have a longer measuring range than that of a prior art detectors. An output signal is stable due to the shielding effect of the yokes. The magnetic closed circuit has many magnetic and mechanical configurations. For example, for the magnet, a permanent magnet and an electromagnet can be used. Further, improvements are proposed for enhancing the linearity of the output signal voltage with respect to the transferring distance of the sensing element and for compensating the offset drift of an amplifier or changing the coercive force of permanent magnets.

    摘要： An optical disk comprising a plastic disk body having fluorescent coloring material dispersed therein. Pits representing stored data are formed on a first main surface of the plastic disk body, a reflecting layer is formed over the first main surface having the pits and a protecting layer is formed over the reflecting layer. When the optical disk is subjected to an external light, the fluorescent coloring material emits a radiation of a fluorescent light of a particular color, which can be seen at the opposite, second main surface and the outer circumferential surface of the optical disk. The optical disk can be also subjected to a laser beam for regenerating data stored in the optical disk.
