Title: Freezing prevention device for boiler
Inventor: BAEK JONG-HU
IPC: F24H9/20
Filed: 1992-08-31
Granted: 1995-10-21
Abstract: The device for preventing the frozen-fracture of the gas-fired boiler in winter, has a PTC(Positive Temperature Coefficient Thermistor) heater mounted at the outer wall of the heating water pipe. The device comprises the PTC thermistor(1) for generating the constant heat by supplying the electric current, attached to the electrode plate(3) with a lead wire connector(2); insulating body(4) attached to the electrode; outer case(5) combined with the thermistor, the electrode and the insulating body, having a pair of guide projections(51); filling material(52) for protecting the movement of the elements, filled in the space of the outer case; elastic clamp(6) for clamping the PTC heater(100) at the pipe(7).

Abstract: 인간 음성의 정상생성에서 성대의 폐쇄 순간은 적절히 규정된 순간에서 일반적으로 발생한다. 이 순간은 관측된 지연 성대 여기 신호와 성문 동기 처리 혹은 음성 합성과 같은 음성 처리를 위해 사용된다. 관측된 음성 신호로부터 성문 폐쇄의 순간을 검출하도록 관측된 음성 신호는 하이 패스 필터되고, 하이 패스 필터된 신호에서 피크의 수 및 진폭의 순간적인 국부집합 성문 폐쇄의 가능한 순간에 의해 결정된다. 성문 폐쇄의 순간은 집합이 최대값이되는 순간으로써 결정된다.
