Patent EP-0726484-A1 (EP)
Inventor: YOSHIDA HIDEFUMI
IPC: G02F1/1347
Filed: 1992-03-09
Abstract: A liquid-crystal device includes a liquid-crystal layer comprising a liquid crystal of a scattering type in which molecules of the liquid crystal are randomly distributed. The liquid crystal layer (14) includes a liquid crystal (14) dispersed in the polymer layer (44) between the first and second transparent plates and first and second polarisers (32,34), for preventing light leakage. In the off state some scattered light penetrates the analyser (32), while in the on state the light is not scattered and hence is blocked by the polariser. For maximising light transmission the liquid crystal panel has a scattering value greater than 1 percent, where the scattering value is defined by the ratio of the intensity of light transmitted by the liquid-crystal panel to that of the source of the laser beam without the liquid crystal.

Abstract: The power supply serves to convert an alternating voltage, supplied by an electric mains, into a desired voltage and comprises rectifier means (1) with input terminals (3) for receiving the alternating voltage and output terminals (5) for supplying a pulsating direct voltage, a first capacitor (7) which is connected parallel to the output terminals, an inverter (9) with input terminals (11) which are connected to the first capacitor, and a current limiting circuit which is connected between one of the output terminals of the rectifier means and an electrode of the first capacitor in order to limit the inrush current occurring when the power supply is switched on. The current limiting circuit comprises a parallel connection of a first resistor (15) and a first switching element (17), the first switching element being operative to be in an electrically non-conductive state upon switching on of the power supply and to change over to an electrically conductive state some time after switching on. In order to establish the state of the first switching element (17), there are provided detection means (20) which cooperate with the start circuit (21) which is operative to generate a start signal for the inverter (9). When the detection means (20) establish that the first switching element (17) is in the conductive state, they prevent activation of the start circuit (21). Consequently, the power supply cannot operate if the first switching element (17) is short-circuited by a defect.

Abstract: In an apparatus for extracting information from an input speech signal, a preprocessor 41, a buffer 42, a segmenter 43, an acoustic classifier 45 and a feature extractor 47 are provided. The preprocessor 41 generates formant related information for consecutive time frames of the input speech signal. This formant related information is fed into buffer 42, which can store signals representative of a plurality of frames. The segmenter 43 monitors the signals representative of the incoming frames and identifies segments in the input speech signal during which variations in the formant related information remain within prespecified limits. The acoustic classifier 45 then determines classification information for each segment identified by the segmenter 43, based on acoustic classes found in training data. The feature estimator 47 then determines, for each segment, the information required, based on the input speech signal during that segment, training data and the classification information determined by the acoustic classifier 45.

Abstract: A method for accessing and using stored electronic documents. The stored documents are presented to the user in a manner which visually simulates document types that most users are familiar with, such as books. Each page of the document is divided into frames. Both the individual pages and the frames comprising them are ranked based on locational, representational and logical attributes. These rankings are called herein semantic hints. The user determines the review speed of the document, and that review speed in turn determines which frames and pages will be moved from memory into cache at any particular time, as well as determining which of the pages and frames will be either fully or partially rendered on the display.
     5. The method of claim 4 wherein the user selected speed determines whether successive or preceding frames are moved from memory to the cache.   6. The method of claim 5 wherein at the third user selected speed, only successive frames are moved from the memory to the cache.

Abstract: A record carrier (36) has a data signal recorded on it which represents data words, added codewords of a first type and added codewords of a second type. The added codewords of the first type have a predefined first relation to the data words. The added codewords of the second type have a second predefined relation to data words and added codewords of the first type. The added codewords of the first and the second type make an error correction possible according to a given algorithm. The data signal is divided into blocks (1) which contain each a control portion (20) with control data and a data portion (21) with user-supplied data. The data words and added first and second codewords are ordered and interrelated in a manner in which the order of the data words, once the error correction has been effected according to the given criterion, is not affected. Furthermore, the application proposes a device for reading a data signal recorded on the record carrier (36). The device comprises first and second error correcting means (45, 47) for correcting errors in the data words in response to the added codewords of the second type and first type. The device further comprises decoding means (50) for separating the control portions (20) of the blocks (1) in response to the data words produced by the first correcting means (45), whilst the results generated by the second correcting means (46) are discarded.

Capacitors (21) are connected in parallel with the individual phases of the stator winding (16) connected to the power system (17). As a result, the magnetizing power no longer has to be supplied by the converter (23) which thus only has to supply the slip power.

Abstract: Procédé de traitement de surface mettant en application une énergie laser pulsée et permettant de texturer et de polir sélectivement des disques à substrats non magnétisables utilisés dans la fabrication de disques magnétiques de lecture et d'enregistrement (16). Les surfaces (44, 92, 100, 119) des substrats sont texturées au-dessus de zones de contact de tête spécialisées (32, 94, 104, 120, 128), de sorte que des nodules multiples (74, 98, 112) extrêmement uniformes soient formés et qu'un contrôle précis puisse être exercé sur la rugosité de surface. Grâce au polissage au laser des zones de données (36, 106, 122) l'écoulement localisé du matériau du substrat supprime les rayures résiduelles du polissage mécanique sans modifier le caractère non magnétique du substrat en général. Entre les zones de données (36, 106, 122) et les zones de contact (32, 94, 104, 120, 128), on peut créer des zones de transition (34, 108) en échelonnant de manière sélective la hauteur des nodules dans le sens radial. La structure arrondie des nodules (74, 98, 112) augmente la résistance de la surface au contact volontaire ou involontaire de la tête de détection. La suppression des rayures résiduelles augmente la résistance à la corrosion et améliore la qualité du signal, étant donné que les couches suivantes, y compris la couche mince d'enregistrement et la couche de protection en carbone, ont tendance à reproduire la topographie de la surface du substrat.
