    摘要: Methods and apparatus, including computer program products, for identifying a language corresponding to a string of data include receiving a data string and dividing the data string into coded character sequences for each of a plurality of languages. A length of one or more coded character sequences varies among different languages for coded character sequences having a particular number of characters. The coded character sequences are analyzed to calculate, for each of the plurality of languages, a probability that the data string corresponds to language. The calculated probabilities are compared among the languages, and a language is identified as corresponding to the data string based on the comparison.

    摘要: The invention comprises methods for manipulating floating point numbers on a microprocessor where the numbers are sortable. That is, the numbers obey lexicographical ordering. Hence, the numbers may be quickly compared using bit-wise comparison functions such as memcmp( ). Conversion may result in a sortable floating point number in the form of a sign, leading bits of the exponent, and sets of digit triples in the form of declets (sets of 10 bits). In a variable-length version, numbers may be compressed by storing the number of trailing zero declets in lieu of storing the zero declets themselves.

    摘要: The present invention relates to a diffractive grating member and to an optical communication module. The optical communication module includes a semiconductor laser;.a coupling optical system for coupling a light flux with a wavelength of λ1 emitted by the semiconductor laser to an optical fiber; and two light-receiving elements for receiving at least two light fluxes each having wavelengths λ2 and λ3 emitted from an end surface of the optical fiber. The coupling optical .system has a diffractive structure, and the coupling optical system changes paths of light fluxes each having wavelengths λ1, λ2 and λ3 into relatively different directions such that the light flux with the wavelength λ1 emitted-by the semiconductor laser enters into the optical fiber and each of the at least two light fluxes each having the wavelengths λ2 and λ3 enters into each of the two light-receiving elements.

    摘要: A zoom lens comprising a negative first lens unit, a positive second lens unit, and a negative third lens unit and having a small backfocus, in which a refracting power of the third lens unit can be intensified to thereby provide a compact zoom lens. An aberration resulting from intensifying the refracting power is corrected by introducing an aspherical surface into the second lens in particular. Furthermore, the first lens unit is divided into two lens components, and the first lens unit is let out while varying a spacing between the two lens components at the time of focussing whereby focussing can be made with less extension amount from an infinite far point to a near distance while preventing degradation of aberrations.

    摘要: A method of producing a lens that includes shifting a first die relative to a second die, and pressing an optical material shaped in a preliminary form between the first die and the second die so as to form a lens having a configuration corresponding to a hollow portion formed by the first die and the second die while shifting the first die relative to the second die. The produced lens includes an effective optical surface configured to converge a light flux. The effective optical surface includes a light entrance side, a light exit side, and an optical axis. The effective optical surface is a convex surface shaped such that when a maximum normal line angle is defined as an angle formed between the optical axis and a normal line at the outermost circumference of the effective optical surface, the maximum normal angle is 60° to 90°.
