Title: Full adder
Inventor: LEE JAE-YEON
IPC: G06F7/50
Filed: 1998-08-24
Abstract: PURPOSE: A full adder is provided to reduce a chip area by realizing the full adder by use of less transistors. CONSTITUTION: The full adder comprises: a first logic gate(206) for receiving a first and a second input signal to output a value of logic "0" when at least one of the input signals has logic "1"; a second logic gate(210) for receiving the first and second input signals to output a value of logic "1" when the input signals have logic "1"; a carry generating part(202); and a sum generating part(204). The carry generating part(202) uses an output from the first logic gate as a pull-up control signal, an output from the second logic gate as a pull-down control signal, and an inverted version of an input carry signal as a clock signal. The sum generating part(204) comprises a third logic gate, first, second and third transfer parts and an inverter. The third logic gate outputs a logic "0" when outputs from the first and second logic gates are "0" and "1", respectively. The first transfer part receives an output from the third logic gate and is turned on by a logic "1" of the input carry signal. The second transfer part receives the input carry signal and is turned on by a logic "0" of the output from the third logic gate. The third transfer part receives an inverted version of the input carry signal and is turned on by a logic "1" of the output from the third logic gate. The inverter receives the outputs from the first to third transfer parts to output a sum signal.

Title: 탄산가스용기가 장치된음료수페트용기
Filed: 1998-09-02
Abstract: 본 발명은 1.5리터 PET병내부에 탄산가스가 충전된 별도의 가스용기를 장치한 PET 병에 관한 것이다.    현재 시중에 나와있는 1.5리터 음료수는 소비자들이 경제적 이익이  있으므로 가정이나 직장 업소에서 많이 애용하고 있다.    그러나 실질적으로 경제적 이익도 있지만 따르는 손실 또한 있다. 
     이상 내용을 구체적 설명하면 다음과 같다. 
     모든 음료수에는 음용시 상쾌한 느낌을 더하기 위하여 탄산가스가 첨가되어 있다.    탄산가스는 가스의 특성 때문에 음료수병을 개봉할 때 마다 쉽게 기화하여 음료수 용기 밖으로 빠져나가게 된다.    이와같이 1.5리터 PET병은 구입하여 1회 개봉시 모든 양을 음용하면 좋으나 보통 1.5리터 음료수를 애용하는 소비자는 1회 개봉후 모든양을 음용하기보다는 필요한 양만 음용후 냉장고에 보관하였다가 수회음용하기 위한 목적에서 많이 애용하고 있다.    하지만 탄산가스는 1회 개봉시 이미 많은 양의 가스는 음료수병 밖으로 빠져나간 상태여서 뚜껑을 닫은 후 보관하여도 2회∼3회 개봉후 음용하면 처음의 음료수의 느낌 상쾌함은 매우 떨어져 있다. 
     본 발명은 이와 같은 문제점을 해소하기 위한 것으로서 PET병 내부에 탄산 가스가 충전된 가스용기를 장치하여 음료수병 뚜껑을 개봉하였을 때는 가스가 토출되지 않게하고 음료수병 뚜껑을 닫았을 때만 탄산가스가 토출되어 음료수병 내부에 첨가 되므로 많은 양이 담긴 음료수를 구입하여 음용후 많은 양이 남아있어도 처음에 음용시 느낌을 끝까지 느낄수 있도록 한 것이다.

IPC: G10L19/002
Filed: 1998-03-05
Abstract: PURPOSE: A transmission system is provided to reduce the delay of the speech signal. CONSTITUTION: In order to reduce the bit rate of the encoded speech signal, the LPC coefficients are only introduced into the data frames, dependent on the difference between the actual LPC coefficients and LPC coefficients obtained by interpolating the LPC coefficients of the previous and the next frames of speech samples. In order to reduce the decoding delay, it is proposed to transmit the LPC parameters from the next frame already in the current frame if the LPC coefficients of the current frame are not transmitted. The interpolation used to obtain the LPC parameters for the current speech frame can already be executed at the beginning of the current data frame.
