    摘要： While high-purity hexagonal boron nitride monocrystal (hBN) obtained by way of a high temperature/high-pressure treatment in the presence of a high-purity solvent has excellent properties in terms of far-UV luminescence characteristics, it has drawbacks including that it can be easily adversely affected by mechanical vibrations and impetus, that monocrystal shows a poor morphological retentiveness and that the luminescence characteristics fluctuate to shift the selected and set wavelength. The present invention can overcome the drawbacks of being easily affected by vibrations and showing a poor morphological retentiveness by grinding down the monocrystal obtained by a solvent/refining process into powder and applying the powder to a light emitting surface. Thus, the present invention provides crystal powder to be used for a far-UV luminescence device showing excellent luminescence characteristics that are stable and do not fluctuate.

    摘要： 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.

    摘要： An apparatus uses a sticky digit in rounding an interim solution Yr into a final approximate solution Ye for an infinite precise solution Y, determined by a function F according to Y=F(X) with respect to digital data X. The apparatus includes a partial product generator receiving a multiplicand and a multiplier, at least one of which represents an interim solution Yr, for generating a plurality of partial products; a sign inversion generator for generating a sign inversion value, expressed in the same format as the partial products, from at least a lower part of a subtrahend to enable place matching, where the subtrahend represents the digital data X; an adder for adding the partial products and the sign inversion value; a detector which, in response to the addition result, detects whether the subtrahend or a product of the multiplicand and multiplier is greater; and a sticky digit generator for generating the sticky digit in response to the detection result.

    摘要： A post-processing is executed on a mantissa M and an exponent E of a floating point binary number as a result of subtraction for example, thereby to obtain a mantissa m and an exponent e of the result of the post-processing. Therefore, an output (E-1) of a decrementer and an output (amount of cancelling of mantissa LSA) of an advancing 1 detecting circuit are entered into a minimum value selecting circuit. The minimum value selecting circuit is adapted to set a shift amount SH to (E-1) and a magnitude-relation judging signal CR to 1 when (E-1) is smaller than LSA (that is, when a denormalize processing is required). When (E-1) is not smaller than LSA (that is, when a normalize processing is required), SH is set to LSA and CR is set to 0. A left shifter is adapted to supply, as the mantissa m of the result, a value obtained by executing a left shift processing having a shift amount SH on the mantissa M. A selecting circuit is adapted to supply, as the exponent e of the result, 0 when CR is equal to 1, and an output (E-LSA) of a subtracting circuit when CR is equal to 0. This enables the denormalize processing of a floating point binary number to be executed at a high speed equivalent to that at which a normalize processing is executed.
