Title: Channel control circuit of satellite broadcasting tv
Inventor: KIM CHUL-JIN
IPC: H04N5/50
Filed: 1987-12-24
Granted: 1991-03-07
Abstract: The channel sync circuit is capable of  receiving  either  TV signal or sattelite signal with only one PLL(Phase  Locked  Loop). The system is different from the old one in using a PLL (300)  and a frequency divider (40). The divider  makes  a  load  oscillating frequency (fL2) from TV tuner (50) and a fL1 from sattelite  tuner (20) to use same PLL by dividing fL1 into two. Then micro-computer (200) program is simple, which means fast  processing  and  simple circuit design.

Title: Multiplexed digital packet telephones system
Inventor: GOLLUB RAPHAEL
IPC: H04B1/66
Filed: 1986-08-20
Granted: 1994-01-19
Abstract: An efficient system for simultaneously conveying a large number of telephone conversations over a much smaller number of relatively low-bandwidth digital communication channels is disclosed. Each incoming telephone speech signal is filtered, periodically sampled, and digitized. An efficient computational speech compression algorithm is applied to transform a sequence of digitized speech samples into a much shorter sequence of compression variables. The compression variable sequence is further processed to construct a minimum-length bit string, and an identifying header is appended to form a packet. Only a few packets containing information on representative background noise are generated during pauses in speech, thereby conserving digital bandwidth. The packets are queued and transmitted asynchronously over the first available serial digital communication channel. Numerical feedback to the compression algorithm is employed which results in the packet size being reduced during periods of high digital channel usage. Packet header information is utilized to establish a "virtual circuit" between sender and receiver.

Inventor: GHISLAIN HUBERT
IPC: B22D11/10
Filed: 1991-08-23
Granted: 1999-07-01
Abstract: The device comprises a main hopper 13 provided with balances 14 and equipped with a draining duct 15 on which are mounted a valve 17 and a flow detector 16. The lower end of the duct penetrates into a secondary hopper 18 connected to a pipe 10 for feeding powder to the mould 1. 
<??>The powder 22 flows from the main hopper 13 into the secondary hopper 18 and is then directed via the pipe 10 into the mould where it spreads over the surface of the cast metal 2. When the level of powder in the secondary hopper reaches the lower end of the duct 15, the flow therein is cancelled and the detector 16 commands the closure of the valve. Its reopening is commanded after a certain period of time or when the powder-presence detector 23 indicates the absence of powder. It is thus possible, by measuring the time between two successive closures or openings of the valves and by weighing the upper hopper, to be continuously informed of the powder consumption.

Title: Copy prevention system of home dvcr
Inventor: YOO BYOUNG-KU
IPC: G11B27/10
Filed: 1993-03-22
Granted: 2000-09-15
Abstract: PURPOSE: A copy prevention system of a D-VCR(Digital Video Cassette Recorder) is provided to prevent copy corresponding to a copy preventing signal of write data by manufacturing a rental tape having the copy preventing signal interpolated into a specific bit of a status byte 3. CONSTITUTION: An interface(1) feeds an HDTV(High Definition Television) broadcasting signal to a fixed terminal(b) of a switch(2). A dummy signal generator(3) outputs a dummy signal to the other terminal(c) of the switch. A status byte check unit(4) short-circuits the switch to the terminal(b) if the status byte 3 included in the output signal of the interface has 0 of a specific byte(b1). An interleave(5) mixes data each other to prevent burst an error. A formatter(6) converts the output data of the interleave into a recording form. A channel modulator(7) maps the data to prevent error when the output data of the formatter are recorded on a tape(8). The HDTV broadcasting signal using the status byte is allowed to record while data of a rental tape are prevented. Therefore, a specific program is managed efficiently.

Title: High-temperature superconductor mixer for low frequency
Inventor: HONG JIN-PYO
IPC: H01P7/08
Filed: 1993-04-30
Granted: 2000-08-16
Abstract: PURPOSE: A high temperature superconductive low frequency mixer is provided, which can be used in a microwave range and has a good packing property. CONSTITUTION: The mixer includes a superconductive resonator(22) and an input line(21) transmitting an RF signal and an LO(Local Oscillator) signal, a bi crystal junction(25) where a frequency transmitted along the resonator is mixed, and an RF choke(26) outputting an IF frequency among the frequencies mixed in the bi crystal junction. First, the RF and the LO signal are sent to the input line, they are transmitted to the superconductive resonator through a gap of 0.3-0.6mm. And, in the resonator, a desired frequency arrives at the bi crystal junction according to the length of the resonator. Then, a mixing by Josephson effect occurs in the junction under the desirable bias current condition, and the IF signal having a frequency difference of two signals is transmitted to the RF choke and therefore a desirable bias current is transmitted to the RF choke part.
