Title: Insulated gate type filed effect transistor
Inventor: SIRATO TAKEHITE
IPC: H01L29/78
Filed: 1986-06-11
Granted: 1990-03-24
Abstract: The device includes a metal insulator FET formed in a transistor area on a semiconductor substrate.  The FET has a source region of opposite conductivity to the substrate, a drain region and a channel region between the source and drain regions.  A gate insulating layer is formed on the channel region and a gate electrode is formed on the insulating layer.  A field area surrounds the transistor area and is provided with a channel stopper region of the same conductivity type as the substrate but with a higher impurity concentration.  The stopper region is formed in contact with the source region and drain region but a part adjacent the channel region is spaced from the channel region.

Title: Device preventing along-distance call
Inventor: LEE IL-HYONG
IPC: H04M1/66
Filed: 1986-07-31
Granted: 1989-10-04
Abstract: The long distance call outgoing from the nonauthorised extension line is prevented by receiving the digit provided from the non-authorised extension line after delay time of the transmission line.  The first digit provided from the extension line is checked after 600 msec. from the first dialling in the private branch exchanger.  The dial signal supplied during the time-divisional decrement of the 600 msec. is disregarded as the non-authorised long distance call.  The authorised call is accomplished with a present junctor in no still- push state.

Abstract: 본 발명에 따른 자기 기록 및 재생 장치에 있어서, 드럼 내의 회전 헤드로부터 성취된 재생 출력은 전류-증폭되고, 그의 저주파 성분은 억압된다. 그후, 재생 출력은 전압-증폭되어, 회전 트랜스포머를 통해 전송된다. 저주파 성분은 회전 트랜스포머의 외부에서 보상되도록 억압된다. 양호한 S/N 및 큰 동적 범위를 가진 재생 증폭 수단은 드럼 내에 구성될 수 있다. 
     더욱이, 재생 증폭 수단의 출력에 접속된 다수의 이퀄라이징 회로는 종단 저항 근처의 이퀄라이징 회로의 주파수 순서로 고주파 성분을 이퀄라이즈하도록 그런 이퀄라이징 회로로 구성된다. 그래서, 이퀄라이즈될 신호의 반사로 진폭 왜율의 감소를 방지할 수 있다.

Title: Digital public address device
Inventor: LEE KI-BONG
IPC: H04H20/76
Filed: 1992-09-24
Granted: 1995-11-08
Abstract: The digital audio signal is transmitted to speakers via relays so that audio signal is transmitted to a plurality speakers with low power. The digital public address comprises a transmitter(100) for transmitting digital audio signal which is obtained by amplifying and converting input analog audio signal into digital signal, a relay(200a) for amplifying the digital audio signal, and a speaker unit(300a) for converting input digital audio signal into analog signal to drive speaker.
