  • Patent number: 7206943
    Abstract: Keys (e.g., decryption key, authentication key) are stored in a non-volatile memory of a display unit. The keys are retrieved in encrypted form into an integrated circuit. The integrated circuit decrypts the keys and uses the keys. As the keys are available in decrypted form only within the integrated circuit and potentially only during use, the keys may not be available to unauthorized third parties.

  • Patent number: 7177329
    Abstract: A transmission efficient packet based display interface arranged to couple a multimedia source device to a multimedia sink device is disclosed. The transmission efficient interface includes a bi-directional auxiliary channel arranged to transfer information between the multimedia source device and the multimedia sink device and vice versa, wherein the information transferred over the auxiliary channel includes a set of packet attributes. The interface also includes a unidirectional main link arranged to carry a number multimedia data packets from the transmitter unit to the receiver unit each having a multimedia data packet header. In the described embodiment, each of the headers is substantially reduced in size over what would otherwise be necessary since the packet attributes are communicated via the auxiliary channel prior to the transmission of the main link packets over main link thereby minimizing the packet overhead and providing a very high main link efficiency.

  • Patent number: 7148900
    Abstract: The object of the invention is to provide a CCM calculating system being relatively inexpensive and alleviating the necessity of a spectrophotometer, a CCM calculating method and a recording medium. A CCM calculating system according to the invention calculates a blending ratio of colorants based on stored color data 16. The system has an input device 5(20b) for inputting data of color specification values corresponding to a desired target color; and a data operation unit 1(20c) for calculating a blending ratio of colorants for reproducing the target color, based on the input data of color specification values and stored color data. Since the blending ratio of colorants for reproducing the desired target color may be calculated based on the input color specification value data and stored color data, such CCM calculation may be performed without the necessity of a spectrophotometer.

  • Publication number: 20060124061
    Abstract: A molecule supply source for use in thin-film forming, enabling to form a thin-film, having a high uniformity, with molecules discharged from a single evaporation source, even on a relatively wide film-forming surface 9, has guide passages 4a, 4b and 4c, being provided in plural numbers thereof, wherein flow rates and directional properties of the vapor molecules are controlled by those guide passages 4a, 4b and 4c; thereby, improving distribution on film-thickness, which are formed on the film-forming surface 9 of a substrate 8. With this, a necessary amount of film-forming material can reach to necessary portions on the film-forming surface 9 of the substrate 8, and therefore, it is possible to reduce dispersion in the film-thickness of the thin-film formed on the film-forming surface 9, but without rotating and/or moving the film-forming surface 9, and thereby enabling to obtain the thin-film, having the uniform film-thickness.

  • Patent number: 7055824
    Abstract: A high pressure shaft seal (10A) for use in a refrigerating machine wherein carbon dioxide is used as a refrigerant in lieu of “Freon”. The seal has a sealing lip (24A) made of a non-elastomeric polymer material such as nylon that has a small gas permeability coefficient, a region of the sealing lip brought into contact with a shaft to be sealed being lined with a low friction lining (26A) of polytetrafluoroethylene. The gas barrier sealing lip (24A) of nylon serves to effectively block permeation of carbon dioxide gas under an extremely high pressure of from about 4 MPa to about 12 MPa. The sealing lip (24A) of nylon has a relatively high rigidity but is nevertheless able to resiliently undergo elastic deformation when such a high pressure is applied, to thereby resiliently follow any shaft run-out to exhibit sufficient dynamic and static sealing functions.
