  • Patent number: 10670453
    Abstract: A sensor unit capable of protecting a piezoelectric element and detecting vibration and sound is provided. The sensor unit comprises a sheet-like piezoelectric element having a porous layer, and a sound propagation sheet covering at least one face of the piezoelectric element and permitting transmission of sound from a first face toward a second face of the sound propagation sheet. A difference in acoustic pressure level between the sound incident on the sound propagation sheet and the transmitted sound is preferably no greater than 10 dB. A surface density of the sound propagation sheet is preferably from 0.03 g/m2 to 100 g/m2. The sound propagation sheet is preferably flexible and preferably has voids. The sensor unit preferably further comprises a sound insulation sheet covering another face of the piezoelectric element and substantially preventing transmission of sound from a second face toward a first face of the sound insulation sheet.

  • Patent number: 5602418
    Abstract: A nitride semiconductor device is made using a molecular beam epitaxy growth apparatus having a gas source for supplying a compound including gaseous nitrogen, solid body sources for supplying Group III constituents, and sources for supplying n-type and p-type dopants. A gaseous state compound containing nitrogen, and a Group III constituent is supplied to the surface of a substrate, wherein the substrate is at a temperature of 300.degree. to 1000.degree. C. and is under a pressure of less than 10.sup.-5 Torr, to produce a first layer of oriented polycrystalline nitride semiconductor on the substrate at a growth rate of 0.1 to 20 Angstroms/second. Subsequently, a gaseous state compound containing nitrogen and a Group III constituent is supplied to the surface of the first layer of the substrate to produce a single crystal nitride semiconductor layer on the first layer at a growth rate of 0.1 to 10 Angstroms/second.

  • Patent number: 5104633
    Abstract: A method and apparatus for producing or manufacturing a high purity metallic silicon takes a process for generating silicon monoxide by causing reaction between a silicon dioxide containing material and molten state metallic silicon. The silicon monoxide thus generated is sucked for reduction by means of a reducing agent including a carbon containing material and a silicon containing material.

  • Patent number: 5095196
    Abstract: A system for examining a passer having an ID card including a photograph and key data for searching registered data of the passer. This system has a data base storing registered data including a video image of the registered ID card owner, a video camera for capturing the passer's figure and a scanner for scanning the photograph of the ID card. The system searches corresponding data, including the video image data, in the data base, using the key data, and displays the found image, passer's image and the scanned photograph image in a display for comparison by an examiner. The system can be combined with a controllable gate system which the examiner can operate based on the results of the examination.
