Patent KR-890005313-B1 (KR)
Title: Key switch
Inventor: MURMANN GUENTER
IPC: H01H13/12
Filed: 1983-08-04
Granted: 1989-12-20
Abstract: A low profile switch key has a base which slidingly supports a pushbutton. The pushbutton is slidingly engaged with a plunger body by a lost motion connection. The plunger body carries cams which control the flexing of contactors to make and break conductive connections with adjacent stationary contacts. A coil spring biases the pushbutton upwardly to its rest position. The sliding lost motion between the pushbutton and plunger body allows the pushbutton to slide by itself over an initial pretravel interval when it is pressed. At the end of the pretravel interval, the pushbutton strikes the plunger body and carries the body downward to complete the key stroke. The plunger body resists sliding movement and therefore provides a perceptible pressure point which indicates actuation of the switch. The stationary contacts and associated overlying cams are interlocked when the pushbutton is depressed to provide a relatively low switch profile with respect to the length of the key stroke.

The  circuit  comprises  a N-clock signal discriminator (200) for checking that input  signal has N- clock period, a delayer (11) for delaying input signal for a fixed time, a first exclusive OR gate (12)  for  operating  output signal of the delayer (11) and input signal, a first AND gate (13) for operating output signals of the N-clock  signal  discriminator (200) and the first exclusive OR gate (12) and a counter (14)  for counting output signal of the first AND gate (13).

Abstract: 본 발명은 연속 폴리올레핀 필라멘트 섬유를 수압교락시켜 직물 웹을 형성시키는 방법에 관한 것이다. 섬유를 60 내지 150 메쉬 스크린 상에 지지시키고 2000psi 이상으로 작동하며 0.7MJ-N/Kg 이상의 총 충격 에너지를 제공하는 고압워터 제트하에 통과시켜 섬유를 교락시킨다. 바람직하게는, 수압교락된 웹을 이후에 300 내지 1200psi의 압력으로 작동하는 미세한 가공 워터 제트하에 통과시켜 섬유를 재분포시킨다. 경우에 따라, 가공제를 교락된 웹에 가할 수 있다. 수득한 수압교락된 웹은 가시 균일도, 불투명도, 유연도, 안락감, 강도 및 차단특성이 선행기술의 웹보다 상당히 증가되기 때문에 1회용 산업용 의류를 제고하는데 특히 유용하다.

Title: Terminal adapter of tip/ring and v-party interface
Inventor: KIM SONG-JO
IPC: H04L12/12

Abstract: The method gives the ISDN service by connecting the modem, G3, FAX, and PC to the ISDN terminal. The device includes a V-series signal converter (1) which converts the TTL signal to the V-interface signal, a speed matching unit (2) which receives the information from data line, a tip/ring terminating unit (3) which gives the tip/ring interface function, a codec and filter unit (4) which has the gain adjust function, a S-transceiver (5) which gives the internal reference clock, a DTMF signal decoder (6) which outputs the decoding data, and a state recognition and controller (7) which specifies the action modes.
