Title: Process for the alpha-chlorination of phenylacetonitriles
Inventor: CASTELIJNS ANNA MARIA CORNELIA
IPC: C07C255/35
Filed: 1992-06-05
Granted: 1999-12-01
Abstract: Process for the  alpha -chlorination of phenylacetonitriles, for example benzyl cyanide, in which the phenylacetonitrile is contacted with a suitable chlorinating agent, sulphuryl chloride or chlorine gas, while an amount of strong acid, preferably HCl, is also present in the reaction mixture. The induction time and the reaction rate are dependent on, among other factors, the concentration of the acid. Preferably, the reaction is carried out under pressure. The reaction is well controllable.

Abstract: 적은 면적을 필요로하고, 적은 베이스 저항을 가지며, 매우 높은 속도로 동작하는데 특별히 적합한 반도체 장치로서, 베이스 저항을 증가시키지 않고 저감된 영역에 형성될 수 있으며 낮은 저항을 갖는 베이스 전극이 마련된 바이폴라 트랜지스터를 마련하기 위해, 바이폴라 트랜지스터가 전극 영역, 예를 들면 베이스 전극이 제1의 영역, 예를 들면 베이스 영역 또는 제2의 영역, 예를 들면 이미터 영역에 대한 자기정합에 의해 형성되고, 다결정 실리콘막의 적어도 위면의 일부와 측면에 금속 실리사이드가 배치되어 전극 영역이 형성된다. 
     이러한 반도체 장치를 사용하는 것에 의해, 베이스 전극이 폭이 다결정 실리콘의 막두께로 결정되므로, 균일하게 좁은 폭으로 형성될 수 있고, 실리사이드를 베이스 전극으로서 사용하므로 베이스 저항이 저감되어, 초미세 초고속의 트랜지스터를 제공할 수 있다.

Abstract: 본 발명은 키폰 시스템에 관한 것으로, 정전시 주장치에 일반용전화기를 따로 부착할 필요없이 키폰자체를 일반전차기로 사용가능케한 키폰시스템에 관한 것이다. 
     종래의 키폰 시스템에서는 정전시 밧데리가 없는 경우에는 키폰을 사용할수 없게되며, 밧데리가 있더라도 장시간은 사용불가하므로 주장치측에서 외부에 일반 전화기를 따로 구비해야 되는 불편함이 있었다. 
     본 발명의 키폰시스템에서는 정전이 발생되는 경우 키폰으로 유입되는 음성 회선을 국선과 연결하고, 국선으로부터 공급되는 전원을 소정직류전압으로 변화시켜 키폰내 각 회로부로 공급하고, 국선을 통하여 착신되는 링신호를 감지하여 CPU에 인지시키고, 송·수신을 위한 경로를 설정하므로, 정 전시에도 국선 통화가 가능하여 키폰시스템에서 따로이 일반전화기를 구비해야 하는 불편함을 해소하게 된다.
