  • Publication number: 20230273083
    Abstract: A metal member with insulating film includes a metal member, an insulating film, and a reinforcement portion. The metal member includes a film formation surface and a connection surface facing in a different direction from the film formation surface and connecting to the film formation surface. The insulating film covers at least a part of the film formation surface and the connection surface over a connection position between the film formation surface and the connection surface. The reinforcement portion is formed along a periphery of the insulating film at the connection position and covers at least a part of the periphery of the insulating film from an opposite side to the metal member.

  • Publication number: 20230131075
    Abstract: [Problem] To provide a pressure sensor that has a plurality of detection parts in a lamination direction, and moreover has improved detection accuracy. [Solution] A pressure sensor 10 has a membrane 22 in which deformation corresponding to pressure occurs, a first gauge layer 40 which is formed on the membrane 22, an intermediate insulation layer 50 which is formed on the first gauge layer 40, and a second gauge layer 60 which is formed on the intermediate insulation layer 50. The first gauge layer 40 and the second gauge layer 60 respectively include a first detection part 42 and a second detection part 62 which detect the deformation of the membrane. The distance from the surface of the membrane 22 to the second detection part 62 is no more than 30 ?m.

  • Patent number: 11076472
    Abstract: A signaling lamp monitor is configured to add a communication function to a signaling lamp such as a stack signaling lamp easily and at a low cost. The signaling lamp monitor includes a detector that detects light emitted from the signaling lamp, a controller that generates a detection signal at least based on the detection, and a transmitter that transmits the detection signal by wireless communication. The transmitter is provided with an antenna disposed above the detector.
