  • Patent number: 7538416
    Abstract: A resin molded type semiconductor device has: a semiconductor chip (12) which is mounted on a die pad portion (11) of a lead frame (9); thin metal wires (14) which connect terminals of the semiconductor chip (12) to inner lead portions (13) of the lead frame (9); and a sealing resin (15), and the lead frame (9) is subjected to an upsetting process so that a supporting portion (11) is located at a position higher than the inner lead portions (13). Since the sealing resin of a thickness corresponding to the step difference of the upsetting exists below the supporting portion, the adhesiveness between the lead frame and the sealing resin can be improved, and high reliability and thinning are realized.

  • Patent number: 7045946
    Abstract: By hiding at least blackened portions from outside to make visual confirmation thereof impossible, a fluorescent lamp keeps its clean outward appearance until its service life expires and insufficiency of luminance on ends of the fluorescent lamp is dissolved. The fluorescent lamp comprising a plurality of discharging electrodes in a glass tube, and wherein the glass tube comprises an illuminating glass tube portion coated at inner wall surfaces thereof with a fluorescent substance and functioning as an illuminating body, and auxiliary glass tube portions provided contiguous to the illuminating glass tube portion and hidden from outside by shielding members, and wherein the discharging electrodes are not provided in the illuminating glass tube portion but mounted in the auxiliary glass tube portions.
