A decryption process chip has a memory in which a first decryption control unit for decrypting a scramble key by using an ECM and an EMM is downloaded from outside and stored. A stream input unit extracts a packet including the ECM based on first information obtained from the first decryption control unit, and the first decryption control unit extracts the ECM from the packet. An STB control unit extracts only data including the EMM based on second information set up from the first decryption control unit, and the first decryption control unit extracts the EMM from the data. The stream input unit indirectly obtains a scramble key decrypted by the first decryption control unit so as to extract the scramble key and transmit it to a descrambler.

The invention has for its object to provide a process of synthesizing high-purity hBN crystal bodies on a robust substrate even under normal pressure.The inventive process of producing hexagonal boron nitride crystal bodies is characterized by comprising a preparation step of preparing a mixture of a boron nitride raw material and a metal solvent comprising a transition metal, a contact step of bringing a sapphire substrate in contact with the mixture, a heating step of heating the mixture, and a recrystallization step of recrystallizing at normal pressure a melt obtained in the heating step. It is also characterized by using as the metal solvent a transition metal selected from the group consisting of Fe, Ni, Co, and a combination thereof, and at least one substance selected from the group consisting of Cr, TiN and V without recourse to any sapphire substrate.
摘要:
A highly pure hexagonal boron nitride single crystal not influenced by impurities and capable of high-luminance short wave ultraviolet light emission reflecting inherent characteristics is provided; a high-luminance ultraviolet light emitting element is provided by using the above single crystal; and utilizing the above element, a simple compact low-cost long-lived far ultraviolet solid-state laser and far ultraviolet solid-state light emitting apparatus are provided. A highly pure hexagonal boron nitride single crystal having a single light emission peak in the far ultraviolet region of up to a wavelength of 235 nm is produced by melting said boron nitride crystal as raw material in the presence of a highly pure solvent under high-temperature and high-pressure, followed by crystallization. A light emitting element or a light emitting layer comprised of the obtained crystal is excited with electron beams, and the thus generated far ultraviolet light resonated or without resonation is taken out.

The present invention relates to an organic-solvent vapor adsorbing apparatus which includes a rotor containing an adsorbent and having tubular draft passages arranged in a direction of the rotational axis thereof. Plate-like separators disposed along a radial direction of the rotor define a plurality of zones. A treatment zone is provided for removing organic solvent vapor from a gaseous stream passed therethrough and into the adsorbent. A regeneration zone is also provided for removing the organic solvent from the adsorbent by a heated air stream passed therethrough. Finally, a purge zone is provided for cooling the adsorbent with cool air. Air exiting the purge zone is merged with the heated air stream which is introduced into the regeneration zone.

A primer comprising a polymer which comprises copolymerized units of an UV absorber having an unsaturated double bond, and a multilayer coated article comprising a substrate, a coating of the primer and a surface coating. The coatings of the multilayer coated article exhibit excellent weathering-resistant adhesion to a substrate, and they improve the surface properties thereof, such as surface hardness, scuff resistance, wear resistance and surface gloss. Accordingly, the coatings can impart excellent durability to the article and inhibit weathering deterioration of the substrate.
摘要:
A method and apparatus for cache lock control are designed for use with a cache memory. The cache memory contains a number of data entries, each divided into segments for storing address information, data, and a cache lock bit, respectively. The cache lock bit, when set in a data entry, prevents updating the address and data in that data entry. An address translator is provided for converting virtual memory addresses to physical addresses. The address translator includes address entries which include at least one segment for storing cache lock information, and cache lock information is transferred from the address translator to the cache memory.
