  • Patent number: 9098054
    Abstract: Disclosed are an interlock switch mechanism and an image formation device. The interlock switch mechanism comprising a main body; a first link rod which is disposed on the main body, and may swing by centering on a supporting point, wherein, a supporting shaft is disposed at one end of the first link rod; a second link rod which is supported by the supporting shaft, wherein, two ends of the second link rod may swing by centering on the supporting shaft; an action part which, under a second force, may touch one end of the second link rod so as to cause another end of the second link rod to swing toward an actuator; and a stroke extension mechanism which, under a first force, may cause the first link rod to swing so as to cause the other end of the second link rod to swing toward the actuator.
    Type: Grant

  • Patent number: 7989088
    Abstract: A novel sub-structure of a thick film dielectric electroluminescent display and a thick film dielectric electroluminescent display incorporating the same is provided. The sub-structure comprises a barrier layer between a substrate and a thick film dielectric layer. The barrier layer is chemically inert with respect to the substrate and the thick film dielectric layer and the barrier layer inhibits diffusion of at least one chemical species therethrough. This sub-structure results in a higher capacitance for the thick dielectric layer, which provides higher display luminance and a reduced tendency for dielectric breakdown of the thick dielectric layer. The barrier layer permits for lower cost substrates, such as glass, to be used.
