  • Patent number: 5106189
    Abstract: A Zeeman atomic spectrophotometer comprising a sample heating means for atomizing a sample, a means for applying a magnetic flux to the atomized sample and a ceramic film coated on at least tips of pole pieces which are disposed facing the heated sample. As the tips of the pole pieces are coated with a ceramic film, the measuring accuracy of the Zeeman atomic absorption spectrophotometer becomes high and stable over a very long term.
    Type: Grant

  • Patent number: 5070594
    Abstract: An acceleration sensor includes a tubular casing having one open and closed by a lid of an elastic material. A magnetic member is received within a sealed space defined by the casing and the lid, and a damper liquid fills in the sealed space. The lid is fixedly connected at its outer peripheral portion to one end portion of the casing including the open end thereof. The lid is deformable away from the other end of the casing so as to absorb a thermal expansion of the damper liquid. The lid has an annular deformable diaphragm portion extending between a central tubular portion of the lid and the outer peripheral portion of the lid. For attaching the lid to the casing, the outer peripheral portion of the lid is pressed into the one end portion of the casing so as to bring the diaphragm portion into contact with the damper liquid, so that part of the damper liquid flows into the tubular portion. Subsequently, an axial bore of the tubular portion is closed by a closure member.

  • Patent number: 4843877
    Abstract: An acceleration sensor comprises a case having defined therein at least one accommodating chamber. At least one magnetic ball is accommodated in the accommodating chamber with a radial play left between the wall surface of the accommodating chamber and the magnetic ball. The magnetic ball is magnetically attracted to a reference position in the accommodating chamber by a magnetic field generating unit. In response to acceleration, deceleration or inclination, the magnetic ball is movable in the accommodating chamber against the attracting force of the magnetic field generating unit. The movement of the magnetic ball is detected by a detector.
