  • LED indicator casing, LED indicator, and LED indicator joint member comprising hanger members
    Patent number: 7994532
    Abstract: An LED indicator casing (1R) has: a casing (1a) including a bottom face (S1), a front face (S2) having an aperture (2a) for light emission, and paired side faces (S3 and S4) adjoining the front face (S2); and paired lead terminals (11 and 12), one of which has a light-emitting element (LED)(21) fitted thereto. The paired lead terminals (11 and 12) are led out to the bottom face (S1) via the paired side faces (S3 and S4) of the casing (1a) respectively.

  • Lead frame and light receiving module comprising it
    Publication number: 20060071289
    Abstract: On a leadframe on which to fix a photodetector element, an element mount frame and a fitting frame are laid with a gap left in between. A shielding frame for electromagnetically shielding the photodetector element is tied, via a tying portion, not to the element mount frame but to the fitting frame. Bending the tying portion brings it into a state in which it covers the photodetector element, but the stress resulting from this bending of the tying portion is shut off by the gap so as not to spread to the element mount frame. On the element mount frame, a circuit element for processing the signal from the photodetector element also is fixed.
