Abstract: PURPOSE:To attain transmission and reception between a main transmission- reception means and plural sub transmission-reception means without executing new wiring to the main transmission-reception means by constituting the distributer of a 1st distribution means and a 2nd distribution means being connected to the post stage of the 1st distribution means and distributing an internal and external signal to plural sub transmission-reception means. CONSTITUTION:An external signal and an internal signal from a main transmission-reception means 3 inside of a master room 2 are distributed to sub transmission reception means of rooms 20, 21, 22 by 1st and 2nd distribution means 62, 57. That is, an external signal, e.g. CATV information is boosted by a booster 63 and the boosted CATV information is fed to a 1st distribution means 62 comprising three 1/2 distributers 64, 65, 66 through a trap circuit 46. The 1st distribution means 62 distributes the external signal to the main transmission-reception means 3 and the 2nd distribution means 57 and distributes the internal signal to the 2nd distribution means 57. The 2nd distribution means 57 is connected to the post-stage of the 1st distribution means 62 and distributes the internal and the external signal to the plural sub transmission-reception means.

Abstract: PURPOSE:To allow plural users to operate a commander simultaneously by sending a command signal in a different timing from plural controllers corresponding to a reference signal from a reference signal generating circuit. CONSTITUTION:A reference signal with a prescribed period from a reference signal generating circuit 13 is sent to terminal equipments 2A-2C via a common bus 3. When a command signal from commanders 24A-24C is sent, the controllers 23A-23C convert the command signal into a compressed command signal and the controllers 23A-23C output the compressed command signal after a delay time specific to respective terminal equipments elapses after the reference signal is received. Thus, even when the commanders 24A-24C are operated simultaneously by plural users, collision of the command signals does not take place through the common bus 3.

Abstract: PURPOSE:To eliminate an energy spread signal component even at the pre-stage of a BPF and to improve an S/N and reception threshold value by taking a difference of signals before and after an energy spread signal elimination circuit after FM demodulation, controlling a channel selection local oscillation frequency is response to the energy spread signal component to be extracted and supplying the result to a mixer. CONSTITUTION:The oscillation frequency of a VCO 4 being a local oscillator is changed in response to the control signal obtained from the addition of the channel selection control signal from a terminal 5 and the energy spread signal from an energy spread signal extraction circuit 13 by an adder 16. The output from the VCO 4 is sent to the mixer 3 and the superimposed energy spread signal component is eliminated in the process of converting an input intermediate frequency IF signal into a 2nd IF signal. Moreover, the pass frequency band width of the 2nd IF signal is extracted by a 27MHz BPF 6. The pass band width of the BPF 6 offers a narrow frequency shift of the energy spread signal in comparison with the conventional BPF 6 and the S/N and reception threshold value of the video signal are improved.

Abstract: PURPOSE:To realize the amplification with high efficiency without causing any switching distortion by introducing the digital processing in switching the power voltage of a power amplification stage according to the amplitude of an input signal in an amplifier amplifying the input signal while applying D/A conversion. CONSTITUTION:A digital input signal Sd is formed into an analog signal Sa after passing through a delay circuit 11 and fed to a power amplifier stage 15. Rectifier circuits 24, 25 output respectively positive/negative voltages VH, VL and -VL, VH. The MSB and 2SB of the signal Sd are fed to AND circuits 41, 51 for detecting the amplitude and AND outputs Sp, Sn are obtained. Since the signal Sd is an offset binary code, the relation between the value of the signal Sd and the amplitude of the signal Sa, the relation between the signals Sp, Sd and between the signals Sn, Sd are as shown in figure (a). In a switching circuit 31, a voltage VL or VH is supplied to a transistor Q1 as the operating voltage with Sp='0' and '1' and a switching circuit 32 is operated similarly with Sn='0' and Sn='1'. Thus, the voltage +VH or -VH is supplied to the amplifier stage 15 only with Sa>=4 and Sa

Abstract: PURPOSE:To obtain the good quality of reproduction of audio and video signals by correcting roughly audio and video information at the 1st time axis correcting circuit and correcting minutely the video signal at the 2nd time axis correcting circuit. CONSTITUTION:The video signal demodulated by a video signal demodulator 22 is applied to a horizontal synchronizing signal separating circuit 23 to separate the horizontal synchronizing signal. The 1st time axis correcting circuit 28 including the circuit 23 uses an error signal obtained from the horizontal synchronizing signal to supply a correcting output for a rough time axis correction of a television signal (audio/video) to a servo mechanism 18 to apply tangential servo. Further, the output of the demodulator 22 is applied to a horizontal synchronizing signal separating circuit 31. The 2nd time axis correcting circuit 37 including the circuit 31 uses an error signal obtained by comparing the phase of the color burst signal with that of a reference sub-carrier for the minute time axis correction with the video signal only.

Abstract: PURPOSE:To always obtain a correct signal free from noises without loading and unloading a caddy, by detecting on abnormal signal contained in a reproduced signal and then actuating a cleaner of pickup stylus with the output of detection. CONSTITUTION:When an abnormal signal is produced in a reproduced signal, a level wave detecting circuit 6 gives a level detection to a pickup signal produced from a pickup circuit 4 to obtain an abnormal detection signal A. This signal A is supplied to a time constant circuit 9. The output of the circuit 9 undergoes a comparison through a comparator 11 to obtain a final detection output. This output is differentiated by a differentating circuit 12 and then added to an arm lifter signal 14 by an adder circuit 13. This added signal actuates a plunger 1 for actuation of a cleaner. Thus a pickup stylus is cleaned. In such a way, it is not needed to unload and load again a caddy in case the dust stickes to the stylus. This process always obtains a correct signal which is free from noises.
