Abstract: This invention concerns a process for processing at least one coded-binary audio flux organized into frames created from digital audio signals which were coded by subjecting them first to a transform from the time domain into the frequency domain in order to calculate transform coefficients then to a quantification and coding stage of the said transform coefficients according to a set of quantifiers, the said set being determined from a set of values extracted from the said signals, values that make up selection parameters of the said set of quantifiers, the said parameters also being present in the said frames. It is characterized in that it includes a partial decoding stage consisting of decoding then dequantifying the transform coefficients produced by the coding based on a set of quantifiers determined from the said selection parameters contained in the said frames of the coded binary audio flux or of each coded binary audio flux, and subjecting the said partially decoded frames to the said processing in the frequency domain, then making the frames thus processed available for use in a later utilisation step.

Title: Amino acid modified polypeptides
Inventor: GRUSKIN ELLIOTT A
IPC: C07K14/00
Filed: 1998-05-20
Abstract: Incorporation of certain amino acid analogs into polypeptides produced by cells which do not ordinarily provide polypeptides containing such amino acid analogs is accomplished by subjecting the cells to growth media containing such amino acid analogs. The degree of incorporation can be regulated by adjusting the concentration of amino acid analogs in the media and/or by adjusting osmolality of the media.

Title: Gas turbine moving blade
Inventor: TOMITA YASUOKI
IPC: F01D5/18
Filed: 2001-02-02
Abstract: A gas turbine moving blade is provided which prevents occurrence of cracks caused by thermal stresses due to temperature differences between a blade and a platform while the gas turbine is being stopped. During steady operation time of the moving blade, cooling air enters cooling passages to flow through other cooling passages for cooling the blade, and then to flow out of the blade. A recessed portion having a smooth curved surface is provided in the platform near a blade fitting portion on the blade trailing edge side. A fillet of the blade fitting portion on the blade trailing edge side has a curved surface with curvature larger than that of a conventional blade fitting portion. A hub slot below the fillet, for blowing air, has a cross sectional area larger than other slots of the blade trailing edge. A thermal barrier coating is applied to the blade surface. By the above construction, thermal stresses due to temperature differences between the blade and the platform during gas turbine stoppage are made smaller and occurrence of cracks is prevented.
