Title: Text processing system
Inventor: HOLLERBAUER WERNER
IPC: G10L21/10
Filed: 1989-10-24
Granted: 1998-05-15
Abstract: A text-processing system in which the sound signal corresponding to a text is applied not only to a speech-recognition device (1) but also to a first further memory (15) for storage, start marks and end marks being allocated to the words detected by the speech-recognition device (1). These marks are related in time to the sound signals stored in the first further memory (15) and are stored in a second further memory (16). In this way a correlation is obtained between the sound signals stored in the first further memory and the individual words detected by the speech-recognition device. The detected words can be reproduced on a display device (13) thereby enabling the sound signal stored in the first further memory and corresponding to a specific detected word to be reproduced acoustically so as to verify the accuracy of a word detected by the speech-recognition device and to correct an erroneously detected word.

Abstract: Draw resonance problems previously encountered when extrusion casting or extrusion coating linear low density polyethylene, LLDPE, are substantially alleviated by use of a polymer designed to have an I2 melt index of from 0.1 to 25 gm/10 minutes, and an I10/I2 ratio from 4.0 to 8.3. Line speeds approaching and even surpassing those attained with LDPE are made possible. This invention can even be used in conjunction with known prior methods for alleviating draw resonance problems with LLDPE and obtain the benefits of the combination.

Inventor: BALZANO JEAN-MICHEL
IPC: H04L12/46
Filed: 1991-09-27
Granted: 1999-11-15
Abstract: An embodiment includes a part (IR) ensuring the functions of the layer 2.1 of a protocol for transmission inside an asynchronous time-division mode telecommunications network (RTTA); and a part (IE) which is a conventional interface for a local area network, ensuring the functions of the layer 1 of a protocol for data transmission inside the local area network (LAN). 
<??>Application to the transmission of data between various local area networks.

Title: Contact hole structure and manufacturing method thereof
Inventor: CHONG IN-SUL
IPC: H01L21/3205
Filed: 1992-03-28
Granted: 1995-09-06
Abstract: a silicon substrate; an active region(2) formed between an insulating isolation region(1) by diffusing impurities; a bird's beak edge portion formed between the active region(2) and the insulating isolation region(1); an insulating film(3) including an etch barrier material(8), formed on the insulating isolation regions(1); and a conductive material layer in contact with the active region(2), the bird's beak edge portion of the insulating isolation region(1), the etch barrier material(8) and the insulating film(3). A semiconductor device with this contact structure has improved junction breakdown voltage and junction leakage current characteristics.

Granted: 1999-07-01
Abstract: 바늘판의 아래쪽에 있어서 루퍼가 회전운동하고, 봉제용의 바늘이 바늘판에 있어서의 바늘구멍을 통해서 상하운동하므로서, 바늘판상의 천에 대해서 봉제가 실시된다.  봉제가 종료되면,  잡아당김편을 작동시키므로서 바늘구멍과 루퍼와의 사이의 개봉실은 측방의 실 유지수단으로 오게되어 이 실 유지수단에 의하여 유지된다.  따라서 그 상태에 있어서 실 유지수단의 위쪽에서 재봉실을 절단해도 루퍼에서 재봉실이 도출되고 있는 상태가 유지된다.
