  • Digital cable television broadcasting receiver
    Patent number: 7804959
    Abstract: A global platform card manager of the IC card chip includes a conditional access software decoding part. A decoding key specific to each conditional access software vendor and a key identification number corresponding to the decoding key are preset in the conditional access software decoding part. The conditional access software encrypted by the conditional access software vendor is decoded using the decoding key designated by the key identification number in the conditional access decoding part, when received.
    Type: Grant

  • Elastic surface wave device and method for making the same
    Patent number: 4234859
    Abstract: This invention provides an elastic surface wave device utilizing Bluestein-Gulyaev wave and constructed by a unitary body of a piezoelectric plate having a plurality of transducers thereon, wherein the wave propagation surface being coated with an insulating rubber and being embedded in molding by an insulating powdered epoxy resin, or whose body is attached on a unitary supporting substrate via double adhesive layers; wherein one layer is composed of one kind of adhesive resin and the other is composed of another kind of adhesive resin different from the former in ultrasonic property. This device is advantageous because it has a low spurious signal level without increasing insertion loss, and is easy to manufacture and inexpensive. This invention also provides an effective method for making the device.
