  • Patent number: 8226377
    Abstract: When a press jig is inserted into a jig insertion hole, an O-ring attached to the outer peripheral surface of the press jig is prevented from being caught on an air supply port opening to the inner peripheral surface of the jig insertion hole and damaged. In a sealing pump-up device 10, the opening diameter of an air supply port 58 opening to the inner peripheral surface of a jig insertion hole 44 provided at one end of an air supply path 60 is set smaller than the strand diameters of an O-ring 72 and an O-ring 96. Consequently, the width at the edge of the air supply ports 58 on which the O-rings 72, 96 may possibly be caught can be made sufficiently smaller than the strand diameter of the O-rings 72, 96.

  • Patent number: 8021204
    Abstract: All lights generated in an organic compound layer are not taken out towards a TFT from a cathode as a transparent electrode. For instance, the light is emitted in a lateral direction (direction parallel to the substrate surface) but the light emitted in the lateral direction is not taken out resultantly, which leads to a loss. Therefore, a light emitting device structured so as to increase the amount of light taken out in a certain direction is provided as well as a method of manufacturing this light emitting device. As a result of etching treatment, an upper edge portion of an insulator (19) is curved to have a radius of curvature, a slope is formed along the curved face while partially exposing layers (18c and 18d) of a first electrode, and a layer (18b) of the first electrode is exposed in a region that serves as a light emitting region.
