  • Patent number: 7813712
    Abstract: With the object of providing an electronic device having good radio signal receiving characteristics with a metal outer case housing therewithin an antenna section without restrictions imposed with regard to material or design, an electronic device minimally having an antenna section 32, an information processing means 33 for processing information that is captured by the antenna section 32, and a metal outer case 31, which houses therewithin the antenna section 32 and the information processing means 33, wherein the metal outer case is configured so that the antenna section 32 can receive magnetic flux from outside via the metal outer case 31 and can resonate, the metal outer case 31 minimally comprising a metal case body member 45 and a metal caseback member 41, and wherein a joining and fixing portion 400 between the metal case body member 45 and the metal caseback member 41 is not provided at a location or in the vicinity of at least a location opposite the substantially center part of the antenna section
    Type: Grant

  • Patent number: 5739588
    Abstract: In a semiconductor device comprising an IC chip (8) mounted on a circuit substrate (7) and sealed with a molding resin (11), corner resist films (6a, 6b, 6c, 6d) are formed at positions corresponding to a corner A of the IC chip (8) on the circuit substrate (7), and the corner A of the IC chip (8) is bonded to these corner resist films by using a die bond (9). A die pattern (3a) is exposed outside the corner resist films, and a power supply pattern (3b) is so formed to encompass their periphery. The power supply terminal, the die pattern (3a) and the power supply pattern (3b) are connected to the IC chip (8) of the corners of the IC chip is improved and peel is prevented. Furthermore, bonding of a large number of bonding wires for supplying power can be freely made.
