Filed: 1997-05-14
Abstract: The present invention discloses a dual conversion RF transceiver (30) which uses only one local oscillator (340) for signal conversion to simplify system complexity and reduce production cost. The transceiver (30) comprises a mixer (313) for mixing input RF signals with first local oscillator signal to generate a first IF signal, an IF filter (314) for filtering the first IF signal, a local oscillator (340) for providing second local oscillator signal, a demodulator (320) for demodulating the filtered first IF signal into first baseband signals by using the second oscillator signal, a baseband circuit (350) for processing the first baseband signals and generating second baseband signals to be transmitted, a modulator (360) for modulating the second baseband signals into a second IF signal by using the second local oscillator signal, and a frequency multiplier for multiplying the frequency of the second IF signal by a predetermined factor to generate a output RF signal. When the transceiver (30) starts receiving the RF signals, the baseband circuit (350) will produce a fixed baseband signal which will be modulated into fixed frequency signal by the modulator (360) by using the second local oscillator signal. And the frequency of the fixed frequency signal will be multiplied by the frequency multiplier to generate the first local oscillator signal.

Title: A reel driving device for a video cassette recorder
Inventor: WOO JEE-SUNG
IPC: G11B15/18
Filed: 1997-11-28
Abstract: Torque is transmitted from a pulley wheel 11 to a gear wheel 41 by way of an intermediate member 31 having two slots 35 cooperating with projections 45 on the gear wheel 41. A pressing plate 60 has upper and lower parts to push the gear wheel 41 into a high position as shown in figure 3 or a low position as shown in figure 5. In the high position, projections 45 will, on rotation of the assembly, abut against upper sloped parts of the slots 35 to lift the gear wheel 41 away from the pressing plate 60, thus avoiding frictional drag. In the lower position of the wheel 41, the projections 45 cooperate with the lower sloped surfaces of the slots 35 to push the wheel down and away from the pressing plate 60. In this depressed position, lower projections on the gear wheel 41 engage with ridges 17 on the pulley wheel 11 to increase the torque transmitted to the gear wheel 41 to achieve a different drive mode.
