摘要： When a spectrally spread additional information signal, obtained by spectrum spreading additional information such as an anti-duplication control signal or copyright information, is superimposed on a video signal, the level of the spectrally spread additional information signal is controlled according to the scatter of pixel values in each block comprising plural pixels. The sensitivity of detecting additional information from the spectrally spread additional information signal is therefore improved, and the visual effect of the spectrally spread additional information signal on a reproduced image is suppressed.

摘要： A method and apparatus for detecting spectrum spread signals by reducing the correlation between the main information signal and the spread signal as much as possible, whereby the detection of a spectrum spread signal is made easier. From an input signal, in which a spectrum spread signal obtained by spectrum spreading an additional information signal has been superimposed on a main information signal, the spectrum spread signal is detected. Using a level adjusting circuit, the gain of the input signal, mainly the main information signal is controlled to reduce the change in the main information signal, or the input signal is sliced at a predetermined level by a slicing circuit to fetch a signal at a predetermined level or lower. A spectrum spread signal detecting unit performs an inverse spectrum spread on an input signal in which the change in the main information signal is reduced, or an input signal with the major portion of the main information signal removed to thereby detect the additional information spectrum spread signal.

摘要： Video signals are converted into one or more blocks for each predetermined unit amount of data, and a discrete cosine transform (DCT) process is performed in the blocks to convert a video signal from a time-base area signal to a DCT coefficient in a frequency area for data compression. One chip of a spread spectrum signal is allocated to each block of the video signal or to each of a plurality of blocks, and additional information is superimposed on the video signal at a constant level corresponding to a chip value for transmission. The video signal on which the additional information consisting of the spread spectrum signal transmitted has been superimposed is received, and from this received signal, a DC component of the DCT coefficient is extracted. Inverse spread spectrum processing is performed for the DC component of the DCT coefficient extracted to detect the additional information.

摘要： Proposed is a powder of ytterbium phosphate having a non-stoichiometric phosphorus to ytterbium molar ratio of 1.08 to 2.0 and having a specified average particle diameter and specified diameter of the crystallites forming the particles. The powder is useful as an infrared-absorbing pigment in a printing ink invisible to naked eyes but detectable by an infrared detecting means for printing of stealth bar code patterns. The ytterbium phosphate powder can be prepared in a convenient and inexpensive method utilizing the precipitation reaction by mixing an aqueous phosphoric acid solution and ytterbium salt solution under specified conditions followed by calcination of the precipitates at a specified temperature and pulverization of the calcined precipitates to give the specified average particle diameter.

摘要： A material and method for bonding a semiconductor device to a pedestal, which can obtain a sufficient bonding strength and stable electric contact, are disclosed. On an n-type electrode constituting an ohmic electrode for a semiconductor laser device are formed a Ni layer and an Au-Sn solder layer. Then, the solder layer is melted and bonded to a heat sink provided with Au-plating. The film thickness of the Ni layer is set to approximately 500 .ANG. or more. When the solder layer is melted, Ni in the Ni layer diffuses into the solder layer and Sn in the solder layer diffuses into the Ni layer. By this mutual diffusion, bonding strength and wettability between the semiconductor device and pedestal can be improved. In addition, by setting the composition ratio of Ni layer to the Au-Sn solder layer to 1.3 wt % or more and under 10 wt %, bonding can be performed at a lower melting point and concurrently a higher bonding strength can be obtained.
