Disclosed herein are a printed circuit board with embedded capacitors therein and a process for manufacturing the printed circuit board. The embedded capacitors are formed by applying a photosensitive insulating resin to a printed circuit board inner layer, and applying a high dielectric polymer capacitor paste thereto. The process for manufacturing a printed circuit board with embedded capacitors therein comprises the steps of: i) laminating photoresist dry films to a copper clad FR-4, exposing to light and developing the dry films, and etching copper foils of the copper clad FR-4 to form bottom electrodes for forming capacitors; ii) applying a photosensitive insulating resin to the surfaces of the bottom electrodes, and exposing to light and developing to etch the photosensitive insulating resin; iii) applying a capacitor paste to the etched regions and curing the capacitor paste; iv) plating the upper regions of the cured capacitor paste and the photosensitive insulating resin using an electroless copper plating process to form copper foil layers for top electrodes; v) laminating photosensitive dry films to the copper foil layers for top electrodes, and exposing to light and developing the photosensitive dry films to etch regions of the dry films except for the copper foil layers where the top electrodes are to be formed; and vi) etching the regions of the dry films except for the copper foil layers where the top electrodes are to be formed, and the dry films formed on the top electrodes are removed so that the capacitor paste is discretely positioned between the top electrodes and the bottom electrodes to form discrete capacitors.

A device comprises a basic clock movement MB whose time indicators are driven by a first barrel connected to a first wheelwork and a first regulator organ, and an autonomous chronograph module MCA whose indicators are driven by a second barrel independent from the first, connected to a second wheelwork and a second regulator organ. The chronograph module is exclusively composed of mechanical elements. The frequency of oscillation supplied by its regulator is equal N times the frequency of oscillation supplied by the regulator of the base movement, with the coefficient N being definable according to a specific application of the chronograph, so that any chronograph module thus previously defined can work with-the same base movement. The chronograph regulator remains constantly engaged with the corresponding wheelwork. The chronograph module allows a time interval to be read with a minimum precision of a hundredth of second. The organs of the base movement and of the chronograph module are arranged in such a way that in assembled state, the height and overall diameter do not exceed 7.75 mm and 30 mm respectively, the dimensions of the chronograph itself being not greater than 4 mm (height) and 30 mm (diameter) when its elements are mounted on a bottom plate, so that the device can advantageously be integrated in the case of a wrist-watch and affords an aesthetic exterior.

It is an object of the present invention to provide a method and apparatus for locating a keyword of a speech and a speech recognition system. The method includes the steps of: by extracting feature parameters from frames constituting the recognition target speech, forming a feature parameter vector sequence that represents the recognition target speech; by normalizing of the feature parameter vector sequence with use of a codebook containing a plurality of codebook vectors, obtaining a feature trace of the recognition target speech in a vector space; and specifying the position of a keyword by matching prestored keyword template traces with the feature trace. According to the present invention, a keyword template trace and a feature space trace of a target speech are drawn in accordance with an identical codebook. This causes resampling to be unnecessary in performing linear movement matching of speech wave frames having similar phonological feature structures. This makes it possible to improve the speed of location and recognition while ensuring the precision of recognition.
