Abstract: PURPOSE: To enable bending of an Si-based material and to remarkably improve the degree of freedom of working of the Si-based material by heating the Si- based material conventionally considered as a material that is very brittle and incapable of being bent, to a temp. equal to or higher than the brittleness- ductility transition temp. of the Si-based material and applying a bending moment to the heated part to effect slip deformation of the material and thereby to enable bending of the material, in this method. CONSTITUTION: An Si-based material has a brittleness-ductility transition temp. at which the state of the material is transited from a state where the material shows brittleness, to a state where the material shows ductility. At a temp. equal to or higher than this transition temp., an Si-based material is in a state where crystal slip is positively caused. Accordingly, when a bending moment is applied to a part heated to a temp. equal to or higher than the transition temp., of the Si-based material, crystal lattice interstitial slip or slip among crystal grains in the heated part is caused to deform the material.

Abstract: 본 발명은 유도 전동기의 스톨 방지 장치에 관한 것으로, 종래 전동기에 흐르는 상전류 만을 가지고 전동기의 스톨을 방지하고자 할 경우에는 계측 도구를 사용하거나 저항값 측정 알고리즘을 이용하지 않는 한 전동기의 고정자 저항값을 알 수 없어서 사용자가 설정하는 전압 보상양으로는 정확한 보상을 하지 못하게 되기 때문에 사용자가 임의로 토오크 부스트양을 필요없이 크게 설정할 수 있으며, 이와 같은 상황에서는 특히 저속 영역의 무부하 상태에서도 과도한 전류가 전동기에 흐르게 되며 또한, 전동기가 가속을 할 경우에는 가속 시간이 빠를수록 가속 토오크가 커지게 되기 때문에 토오크 부스트양에 의해 흐르는 전류와 부하 토오크 및 가속 토오크에 의한 전류가 모두 전동기에 흘러 저속 영역에서 큰 전류를 필요로 하게 되는 문제점이 있었다. 따라서, 본 발명은 유도 전동기의 1차측 상전압과 상전류와의 상차각인 역률 정보를 이용함으로써 인버터의 스톨 방지 기능을 사용하여도 토오크 부스트양에 관계없이 저속 영역에서도 전동기를 원활히 가속할 수 있도록 하는 효과가 있다.

Title: Data link protocol for wireless systems
Inventor: KRISHNAMOORTHY RAJEEV
IPC: H04W28/04
Filed: 2000-07-26
Abstract: PURPOSE: A data link protocol for wireless systems is provided to make time slots appear with the different frames that are transmitted by the various radio beams. CONSTITUTION: A two layered segmentation technique coupled with a two layer error detection technique is used to implement the wired to wireless network interface. A wireless network divides network layer packets from a wired network into radio data link packets, and the information within the radio data link packets is divided into portions that can be placed into time slots. Error detection is performed on each of the time slots and also at the radio data link packet level to determine if there is an error within the radio data link packet. Errors detected in any radio data link packet only requires retransmission of the radio data link packet in which the error was detected, and, advantageously, do not require retransmission of the entire network layer packet as would have been required in a system that mapped directly from network layer packets to time slots.
