    摘要： Method and apparatus for use with digital television receivers are included among the embodiments. In exemplary systems, components of an interfering analog television signal (e.g., an NTSC signal) in the same channel as a DTV signal are separately estimated and canceled from the DTV signal. For instance, separate frequency shifters produce shifted versions of the DTV signal, each shifter placing one interfering NTSC carrier signal at or near DC. A DC detector detects the NTSC carrier strength for each carrier, and carrier cancellation signals are synthesized based on these measured carrier strengths. This rejection filter is simpler than prior art filters that require phase-lock on the interfering carriers, and also allows the filter to operate when phase-lock on interfering carriers is difficult to obtain. Other embodiments are described and claimed.

    摘要： A method for electrophotographically forming a Braun tube's fluorescent layer coats conductive and photoconductive layers on the internal surface of a Braun tube's panel. The photoconductive layer is formed of a water soluble photoconductive liquid including a water soluble binder, allowing a part of the photoconductive layer to be selectively exposed to a visible ray. The photoresist of the above photoconductive liquid is substituted with dye, which can be processed through general exposure and solvent, allowing the fluorescent layer to be formed on a Braun tube under the same conditions as a typical Braun tube production process without darkroom processing.

    摘要： A nitride semiconductor light emitting device includes n-type and p-type nitride semiconductor layers, and an active layer disposed between the n-type and p-type nitride semiconductor layers and having a stack structure in which a plurality of quantum barrier layers and one or more quantum well layers are alternately stacked. A net polarization of the quantum barrier layer is smaller than or equal to a net polarization of the quantum well layer. A nitride semiconductor light emitting device can be provided, which can realize high efficiency even at high currents by minimizing the net polarization mismatch between the quantum barrier layer and the quantum well layer. Also, a high-efficiency nitride semiconductor light emitting device can be achieved by reducing the degree of energy-level bending of the quantum well layer.
