  • Patent number: 8486240
    Abstract: A corrosion-resistant ceramic electrode material includes ceramic particles and, present between them, a three-dimensional network electroconducting path composed of a reductively fired product of a carbon-containing polymeric compound. This material is manufactured by a method in which a polymerization reaction of a polymerizable monomer previously contained in a ceramic slurry is performed to gel the ceramic slurry to thereby give a green body; and after drying and degreasing, the green body is fired in a reducing atmosphere.

  • Patent number: 7560040
    Abstract: A tuning-fork crystal wafer 1A which has legs 11, 12 with grooves 11c, 12c is shaped by etching of a crystal substrate 2. To improve processing precision of the depth of the grooves 11c, 12c, the width of the grooves 11c, 12c is set in advance, based on the etch stop technique in which the amount of etching depends on the pattern of an etch portion. Consequently, as far as the etch time satisfies a required minimum time, it is possible to obtain the depth as designed.
