Abstract: The method for insulating a semiconductor layer on an insulator comprises: (a) forming an insulating layer (22) on a semiconductor substrate (20) and opening a window (24) on a base surface for epitaxially growing by partially etching the insulating layer (22); (b) forming a semiconductor layer (26) on the base surface inside the window (24) and on the insulating layer (22) with the same crystalline structure as the semiconductor substrate (20); (c) forming an active region (30) by photolithography; and (d) forming a silicon nitride film(32) for spacer on the side wall of the active region (30). Semiconductor elements of high quality can be produced.

     (상기 식에서, R은 탄소수 3 ~ 8의 시클로알킬기이고, X는 할로겐원자이며, Z는 다음 구조식 : 
     
       
     
     의 기를 나타내며, 상기의 시클로알킬기는 탄소수 1 ~ 6의 알킬기로 치환될 수 있다). 
     이를 제조하는 방법 및 활성성분으로서 이러한 화합물을 함유하는 제초제가 기술되어 있다. 이러한 화합물은 저용량으로 농장 및 논에 있는 잡초상에 놀라울 정도의 높은 제초효과를 보여주지만 주요 농작물에는 독성 효과가 거의 없는 우수한 효과를 가지고 있다.

Title: Circular weaving machine with vertically moving heddles
Inventor: ZIEGLER JOSEF
IPC: D03D37/00
Filed: 1992-04-17
Granted: 2000-04-15
Abstract: 2. The circular loom according to the invention serves for producing tubular fabrics and has an annular frame with an upper ring plate (10) and a lower ring plate (12). Vertically movable healds (32) serve for guiding the warp yarns (36) and are mounted at a uniform distance from one another on at least one circular track (38). For mounting and guiding the healds (32), bearing bores (40) are made in the two ring plates (10,12). The healds (32) have, at their lower ends, cam-follower rollers (42) which run on an associated control disk (44). <IMAGE>
