  • Publication number: 20130241356
    Abstract: Disclosed herein is a probe for an ultrasonic diagnostic apparatus including a transducer module that transmits and receives ultrasonic waves. The transducer module includes a piezoelectric device transmitting and receiving ultrasonic waves, at least one matching layer disposed on the front surface of the piezoelectric device, a backing layer disposed on the rear surface of the piezoelectric device, a backing block disposed on the rear surface of the backing layer, and a gas layer disposed between the backing layer and the backing block. Since acoustic energy proceeding in the backward direction of the piezoelectric device is reflected by the gas layer toward the piezoelectric device, sensitivity of the transducer module is improved.

  • Patent number: 8519627
    Abstract: Provided is a field emission device having a simple structure and capable of pulse driving and local dimming. The field emission device turns a current flowing from each cathode electrode block on or off in response to a switching control signal having a very low voltage ranging from 0 to 5 V while a constant voltage is applied to an anode electrode and a gate electrode to control a field emission current. Compared with a conventional field emission device, the field emission device having a simple structure is capable of pulse driving and local dimming without using a separate pulse driving high voltage power source.

  • Patent number: 8264151
    Abstract: A field emission device having a simple structure and capable of readily changing emission colors of light by adjusting emission intensity of red, green and blue light is provided. In the field emission device, current that flows into each cathode electrode block is adjusted according to a very low control pulse signal of 0 to 5 V with a predetermined voltage applied to an anode electrode and a gate electrode over time, so that emission intensities of red, green and blue are individually adjusted. Therefore, the current that flows into each cathode electrode block is adjusted in a simple manner using a control pulse signal of a low level without a separate pulse driving high-voltage power supply, so that emission intensities of red, green and blue can be arbitrarily adjusted and emission colors of the field emission device can be readily changed.
