Abstract: An improved connector (8) for connection to and identification and testing of electric components such as integrated circuits is described which features a number of spring biased contact elements (12) normally in contacting relation with a shorting bar (14). When a particular component (20) is placed in a specified physical relation to the connector (8), a combination of exposed electrical contacts (28) and nonconductive elements (22b) on the component to be tested displace specified ones of the contact members (12) away from the shorting bars (14), providing a connection pattern which can be detected. At the same time, test signals can be applied to the electric component (20) to be tested. The circuit may be identified and its specific parameters identified and characterized in a single operation according to the invention. Advantageously, the shorting bar (14) is grounded so that any static charge on the component (20) to be tested is grounded before the contact elements (12) are displaced from the shorting bar (14).

     본 발명의 빠징꼬 군에 의하면, 그 빠징꼬 군에서 나온 빠징꼬 구슬은 확실하게 그 빠징꼬 군 내에 회수됨과 동시에, 계수기를 공용으로 할 수 있어서, 설비에 고액의 비용을 들이지 않고, 빠징꼬 군 사이에서 보유하는 빠징꼬 구슬 수의 균형이 유지되며 구슬부족이나 막힘을 방지할 수가 있다.
Patent KR-940008858-B1 (KR)
Title: Key-extension method for portable pc
Inventor: SONG YONG-JU
IPC: G06F3/02
Filed: 1991-10-24
Granted: 1994-09-28
Abstract: The method provides the key extention by replacing a key which processes three key codes with key compounding. The method comprises: a CPU (1) controlling the whole system, a keyboard logic (2) comprising a keyboard controller and a scan key controller, which outputs scan code and break code. The method receives the key input from keyboard (3), then output the scan code to CPU, and output the keyboard interrupt signal from CPU to the keyboard.
