Abstract: PROBLEM TO BE SOLVED: To decrease the shortening of respective pieces of wiring and disconnection defects and to improve the yield or production and dependence on visual angle by constituting the liquid crystal display device in such a manner that the three refractive indices of a refractive index ellipsoid of a phase difference plate have a specific relation, that this refractive index ellipsoid is tilted and that alignment layers have plural alignment regions in respective pixel regions corresponding to respective pixel electrodes. SOLUTION: The pixel electrodes 9 are divided at an area ratio 17:3 to divided pixel parts 9a, 9b varying in liquid crystal alignment. Reference lines 38 pass in the spacings between these parts. As a result, the visual angle dependence of a specular visual angle direction may be improved. The three main refractive indices na, nb and nc of the refractive index ellipsoid at the phase difference plate have the relation na=nc>nb and one of the main refractive indices na, nc is parallel with the surface of the phase difference plate. The main refractive index nb is rotated to the state inclining from the state parallel to the normal direction of the surface of the phase difference plate around the direction of the paralleling main refractive indices, by which the refractive index ellipsoid is inclined.  The alignment layers have the plural alignment regions subjected to the alignment treatments respectively varying in the respective pixel regions corresponding to the respective pixel electrodes.

Abstract: Machine-side coupling halves (27, 15) of the coupling device can be coupled by means of hydraulic drive cylinders (23, 15a) to the coupling halves (26, 14) of the mould halves (Sa; Sb) of the injection mould. A coupling (F) thereby formed on the movable mould half (Sb) is designed for coupling up the supply lines for the performance of operative mould functions in both mould halves (Sb, Sa) and the coupling (T) formed on the stationary mould half (Sa) is designed for coupling up the supply lines for the temperature-control medium for the purpose of controlling the temperature of the two mould halves (Sa, Sb). This achieves the effect that the couplings for the temperature control and the couplings for the as-required operative functions of the injection mould are separated from each other and, as a result, according to scale and operating location, can be adapted better to the specific requirements of the prospective purchaser and nevertheless a temperature control of the injection mould outside the clamping space is possible.

Abstract: The invention relates in general to low bit-rate encoding and decoding of information such as audio information. More particularly, the invention relates to computationally efficient adaptive bit allocation and quantization of encoded information useful in high-quality low bit-rate coding systems. In audio applications, a digital split-band encoder splits an input signal into frequency subband signals having bandwidths commensurate with the critical bandwidths of the human auditory system, quantizes the subband signals according to values established by an allocation function, and assembles the quantized subband signals into an encoded signal. The allocation function establishes allocation values in accordance with psychoacoustic principles with allowance for decoding synthesis filter bank spectral distortions. In one embodiment, an allocation function establishes allocation values using a psychoacoustic masking threshold generated by estimating the power spectral density (PSD) of the input signal, generating an excitation pattern by applying a basilar-membrane spreading function to the PSD, adjusting the excitation pattern by an amount equal to a sensitivity function which specifies a signal-to-noise ratio (SNR) sufficient to achieve psychoacoustic masking, comparing the level of the adjusted pattern to the threshold of hearing and generating the psychoacoustic masking threshold which is equal to the larger of the two. An allocation function may allow for decoder synthesis filter bank spectral distortions in any of a number of ways such as by adapting the sensitivity function.
