Patent KR-970011059-B1 (KR)
Title: Battery - powered device
Inventor: SCHMIDT ROBERT H MUNNING
IPC: G01R31/36
Filed: 1988-07-04
Granted: 1997-07-05
Abstract: If when a load (RL) is powered by a battery (6) first detection means (100) detect that the expired discharge time measured by measurement means (40, 70) is equal to the first reference value stored in a memory (22), first time measurement means (40, 80) measure the time during which the load (RL) is powered by the battery (6). When the load (RL) is switched off and is not connected to the mains voltage via a power-supply circuit (1), the battery (6) is discharged by a discharger (9). Second time-measurement means (50, 80) measure the time during which this discharger (9) is operative until second detection means (13) detect a battery voltage for which the battery (6) may be regarded as fully discharged. After comparison of the sum of the time intervals measured by the first and the second time-measurement means with a second reference value stored in a memory (21), the correction means (10) correct the reference value stored in a memory (22) in such a way that during a next discharge the sum of the time intervals measured by the first and the second time-measurement means is better in agreement with the second reference value.

Abstract: PCT No. PCT/EP87/00723 Sec. 371 Date Jul. 21, 1988 Sec. 102(e) Date Jul. 21, 1988 PCT Filed Nov. 20, 1987 PCT Pub. No. WO88/04117 PCT Pub. Date Jun. 2, 1988.In the transmission of audio signals, the audio signal is digitally represented by use of quadrature mirror filtering in the form a plurality of spectral sub-band signals. The quantizing of the sample values in the sub-bands, e.g. 24 sub-bands, is controlled to the extent that the quantizing noise levels of the individual sub-band signals are at approximately the same level difference from the masking threshold of the human auditory system resulting from the individual sub-band signals. The differences of the quantizing noise levels of the sub-band signals with respect to the resulting masking threshold are set by the difference between the total information flow required for coding and the total information flow available for coding. The available total information flow is set and may then fluctuate as a function of the signal.

Abstract: 본 발명은 와이얼리스 수신기에 관한것으로, 적외광을 사용하여 오디오 신호를 스피커에 전송하는 경우 스피커와 일체로 설치되어 송신기의 전송광을 수신하는 와이얼리스 수신기에 있어서, 전송광의 유무의 검출출력에 의하여 수신기의 메인전원을 온 오프함에 따라 수신기의 전원스위치를 조작하지 않아도 되도록한 것이다. 
     종래의 스피커장치는 사용자가 스피커장치의 전원의 온.오프를 리모콘으로 할필요가 있으며, 이것을 잊어버리면 음이 나오지 않거나 전지가 낭비되어 버리고, 디코더는 항상 통전하여 둘필요가 있어 일반적으로 디코더는 소비전류가 크므로 실용적이지 못하다. 
     또한, 다른 스피커장치는 사용자가 스위치를 손으로 조작할 필요가 있고, 비록 스피커에 의한 재생중이라 할지라도, 스위치를 조작하거나 일정한 시간이 지난후에는 타이머회로에 의해 스위치 회로가 강제적으로 오프되어 재생이 중단되어 버린다. 
     이에따라, 본 발명은 상기와 같은 문제점을 해소하기 위한 수단으로써, 오디오신호에 의해 FM변조된 FM신호를 수신하여 오디오신호를 출력하는 FM수신회로와, FM수신회로로 부터 출력되는 오디오신호를 증폭하는 파워앰프와, 파워앰프로 부터 오디오신호가 공급되는 스피커와, FM수신회로 및 파워앰프의 전원라인과의 사이에 직렬접속된 트랜지스터와, FM신호의 유무를 검출하는 검출회로를 설치하여 검출회로의 출력에 의해 전원스위치용 트랜지스터의 온 오프를 제어함에 따라, 사용자는 스피커로 부터 재생음을 출력시킬때도 전원의 스위치를 전혀 조작할 필요가 없고, 외부광이 노이즈가 되지만, 오디오신호를 FM신호로 변환하고 상기 FM신호로 적외광을 변조하고 있으므로, 외부광의 영향을 그다지 받지않도록한 와이얼리스 수신기에 관한 것이다.

A write amplifier(3) amplifies output(V2) of the format converter and records the data on a tape through a head(HD1). A read amplifier(4) amplifies detected signals(V4) of the head up to a specific level. A video demodulator(5) outputs the original signals(Vo) by demodulating output(V5) of the read amplifier. If the video data are recorded on every n frames, the video demodulator restores the video data by playing back the video data repeatedly n times. Thereby, the video data are reproduced for a long time.

Title: Device for pipe and supply of draft beer
Inventor: LEE KYU-SHIN
IPC: B67D1/08
Filed: 1993-04-02
Granted: 1997-04-23
Abstract: The both ends of the transporting device(10) are connected with the beer inlet tube(12) and the hose assembly(32). With one end connected to the draft beer cylinder(101), the other end of the transporting hose(31) is connected with the hose assembly(32) of the delivery system(10). Equipped with a flow meter(40), the beer transporting hose(31) is connected to the distribution tube(11) through the hose assembly(32). And the flow meter(40) is connected with the counter display(41) and the table display(42), which shows the quantity of draft beer transported and the amount thereof. The multiple lines of transporting hoses(31') reach the open/close valve(35) on the drinking table.

Title: Ball grid array package with degating area on pcb board and the molding method
Inventor: HU YOUNG-WOOK
IPC: B29L31/34
Filed: 1993-08-18
Granted: 1997-07-07
Abstract: the step of positioning a PCB where a degating region, which is used as a mold runner gate and makes the degating of an excess resin easy, is formed in a mold; the molding step of forming a resin encapsulant on the top surface of the PCB by hardening and passing the fused resin encapsulating material through the degating region of the PCB; and the excess resin removing step of removing the hardened excess resin remained on top of the degating region.

Title: Median strip
Inventor: BAEK CHON HO
IPC: E01F15/00
Filed: 1993-08-31
Granted: 2003-01-08
Abstract: PURPOSE: Structure and method for an assembling median strip are provided to prevent injury and breakage by buffering impact with a tire at a collision, to reduce accidents by indicating a night warning display, and to modify the lane easily by moving the structure simply. CONSTITUTION: Plural structures are arranged along the median strip or the shoulder of the street, and connected in a line. The structure has a trapezoid pedestal(1) forming recesses(2) continuously for storing standing tires(5) and recessed curved surfaces at sides, plural tires arranged and overlapped in the recesses, and a supporting shaft(4) having plural connecting links(11) at both sides of the pedestal. Structures are connected by inserting shaft bolts(12) to connecting links. Plural rollers(3) are rotated axially and arranged in the lower part of the pedestal, and a grip(17) is mounted in a frame of a light shield net. Injury is relieved by buffering impact at a collision with using the waste tire, and noise is absorbed. The lane is modified conveniently by moving the structure easily.

Title: Overload protection method of inverter
Inventor: JUNG INN-HAK
IPC: H02M1/32
Filed: 1993-09-21
Granted: 1997-03-27
Abstract: The method for protecting damages of the inverter and load caused by over-load of the inverter which converts ac power to dc one and drives loads such as motors with the switched dc power detects over-load state exactly when the loads are driven with low frequency band which is below 20 Hz. The method comprises steps; a) reading the detected current flowing through a load(3) and running frequency of the load; b) compensating the detected current to be proportional to the load current when the read running frequency is lower than reference one; c) determining the over-load state with the compensated current; and d) turning off the inverter when it is on over-load state.
