  • Resin encoder scale, mold for resin encoder scale, method for producing resin encoder scale, and encoder
    Patent number: 10288453
    Abstract: A purpose is to provide a resin encoder scale a cost of which can be reduced by making processing easy by producing the encoder scale as a resin molded piece including a scale pattern. A resin encoder scale is used in a reflection-type optical encoder and a scale pattern for position measurement is provided thereto. In the scale pattern, a low reflection part a surface of which is molded as a rough surface during resin molding and which has low reflectivity of light and a high reflection part a surface of which is molded as a mirror surface during the resin molding and which has higher reflectivity of light than the low reflection part are arranged alternately.

  • Fuel cell
    Patent number: 9203102
    Abstract: A membrane electrode assembly of a fuel cell includes a solid polymer electrolyte membrane, a cathode, and an anode. The surface size of a cathode side electrode catalyst layer of the cathode is smaller than the surface size of an anode side electrode catalyst layer of the anode. An inner end of a gas impermeable film provided around the anode side electrode catalyst layer and an outer end of a cathode side electrode catalyst layer are overlapped with each other on both sides of the solid polymer electrolyte membrane.
