Abstract: A chrominance signal demodulation circuit capable of precisely processing a chrominance signal demodulation even when a phase of an inputted chrominance signal is abruptly changed due to a tape track skew error. A first and second color difference signals in an R-Y axis and B-Y axis directions are obtained by multiplying a color burst signal of the inputted chrominance signal and color subcarrier signals generated by a color subcarrier generator. A demodulation phase detector 17 generates a phase error signal to compensate a phase difference between the phases of the color burst signal and the color subcarrier signal based on the first and second color difference signals obtained. The color subcarrier generator 12 generates color subcarrier signals compensated responsive to the phase error signal. Thereby, a chrominance information portion following to the color burst signal in the inputted chrominance signal is successively processed with a chrominance signal demodulation with a correct phase.

Abstract: A low-profile optically-sensitive semiconductor device is disclosed which includes a substrate with an opening. A cover plate is bonded to a first surface of the substrate in such a manner that a optically-sensitive semiconductor chip is adhered thereto via the opening of the substrate.

A sealing plate is then attached to the first encapsulant to seal the through hole, so as to hermetically separate the semiconductor chip from the atmosphere. On the first surface of the substrate, a second encapsulant is formed such that ends of the conductive elements and an outer surface of the cover plate are exposed to and flush with a top surface of the second encapsulant.

Abstract: There is provided an apparatus for storing/restoring holographic data and a method for coding/decoding holographic data. In a recording mode, the apparatus divides input data into a plurality of groups, each of which includes two binary digits; and encodes each of the groups into a 2×2 data block wherein a first row of the 2×2 data block has the two binary digits and a second row thereof has another binary digits generated by applying a binary differential calculation on the first row. In a restoring mode, the apparatus divides a signal restored from a storage media into a plurality of 2×2 data blocks; and decodes each of the 2×2 data blocks into two binary digits by comparing values of a first row of the 2×2 data block with those of a second row thereof. In this way, phenomena of isolated “on” or “off” can be avoided.
