Abstract: A glass disk is subjected to a chemical or gentle mechanical polishing step to remove microcracks or scratches in the disk surface prior to chemically texturing the disk. Thereafter, magnetic media is deposited onto the glass disk. The pre-texturing polishing step avoids the phenomenon of "linkage bumps", which could otherwise cause the resulting magnetic disk to fail a glide-type test or to cause a read/write head crash.

Abstract: A bar code reading system produces a binary signal from an analog signal containing a bar code signal, and derives from the binary signal appropriate bar code data. The bar code reading system comprises an amplitude increase detector (9) for detecting when the amplitude of the analog signal changes steeply, and a sequence controller (18) for controlling an output of a demodulator (10) that demodulates the binary signal to produce the bar code data. When the amplitude increase detector (9) provides a detected signal, indicative of a steep increase in the analog signal, the sequence controller (18) carries out its controlling task as if the bar code has a normal white margin even if the white margin produces noise. 
     Such a system can correctly recognize the start of the bar code irrespective of noise and can enable a lower limit threshold level, below which the analog signal is effectively ignored, to be lowered, thereby improving dynamic range.

Abstract: A positive-type photoresist composition is described as including:
     (1) an alkali-soluble phenol novolak having a degree of dispersion of from 1.5 to 4.0;   (2) a 1,2-quinone diazide compound; and   (3) from 2 to 30% by weight, based on the above-mentioned novolak, of a low molecular weight compound having a total of from 12 to 50 carbon atoms per molecule and 2 to 8 phenolic hydroxyl groups per molecule. The degree of dispersion is determined from a weight-average molecular weight of the novolak and a number-average molecular weight of the novolak, both the weight-average and number-average molecular weights being obtained by gel permeation chromatography (GPC) defined by using standard polystyrene as a reference, such that the degree of dispersion is a ratio of the weight-average molecular weight to the number average molecular weight.   
     The positive-type photoresist composition of the present invention is excellent in development latitude and has a high sensitivity and a high resolving power. Thus, it is suitable for use in, for example, the production of semiconductors such as integrated circuits, the production of circuit substrates for thermal heads, and photofabrication processes.

Abstract: Compatibility improvement apparatus for the use within standard MAC decoders when receiving HDMAC signals. 
     Due to the 4-field encoding technique combined with line shuffling, the compatible pictures suffer from edge crawling and dot pattern artefacts with a flicker frequency of 12.5 Hz. Within moving picture areas the viewer perceives a motion judder which results from the synthetic interlace applied within the 40ms transmission mode. 
     A D2-MAC standard decoder is modified by including a compatibility improvement filter. This filter is motion adaptive and will be switched by the motion information of the DATV signal. 
Advantageously this filter is suited, too, for standard decoders which provide progressive scan lines at their output.

Abstract: An image data encoding system efficiently reconstructs an image through a progressive image buildup in stages. An original image is divided into blocks each having NXN picture elements, whose transformation coefficients are obtained by orthogonal transformations on their graduated values. 
     The image data encoding system has a transformation coefficient memory (61) for storing transformation coefficients; a mask information memory (62) for storing mask information for masking transformation coefficients; a masker (63) for masking the most significant bits of the transformation coefficients specified by mask information; a shift information memory storing quantization thresholds for quantizing the transformation coefficients; and a quantizer (65) for quantizing the masked transformation coefficients per the quantization threshold. 
     The quantization threshold can be given a value of 2 to an integer power, and quantization can be attained by shifting bits of the transformation coefficients towards less significant bits by that power.

Abstract: Method and apparatus for automatic recognition of handwritten text based on a suitable representation of handwriting in one or several feature vector spaces(s), Gaussian modeling in each space, and mixture decoding to take into account the contribution of all relevant prototypes in all spaces. The feature vector space(s) is selected to encompass both a local and a global description of each appropriate point on a pen trajectory. Windowing is performed to capture broad trends in the handwriting, after which a linear transformation is applied to suitably eliminate redundancy. The resulting feature vector space(s) is called chirographic space(s). Gaussian modeling is performed to isolate adequate chirographic prototype distributions in each space, and the mixture coefficients weighting these distributions are trained using a maximum likelihood framework. Decoding can be performed simply and effectively by accumulating the contribution of all relevant prototype distributions. Post-processing using a language model may be included.
