Title: Thermomagnetic recording and reproducing device
Inventor: HANAOKA HISAHIRO
IPC: G11B5/00
Filed: 1979-03-15
Abstract: PURPOSE: To make it possible to enhance a recording density considerably by providing an auxiliary magnetic pole to converge the magnetic flux given to a recording medium.  
     CONSTITUTION: The laser light from light source 4 is given to half mirror 6 through light modulation unit 5 and polarizer 5 1  and is reflected and is given to the surface of magnetic thin film 2 through lens 7. When the laser light is focused on thin film 2, the spot part is heated to lower coercive force. Under this state, when a magnetic field corresponding to a recording signal is generated from coil 10, the magnetic flux dependent upon the magnetic field magnetizes the part of thin film 2, thus recording prescribed information. In this case, the generated magnetic flux of coil 10 is converged to the part of very narrow ferromagnetic material 14 of auxiliary magnetic pole 11 and is given to the heated part of thin film 2 from the vertical direction. Consequently, even if the heated part of the laser light spot focused on thin film 2 has a spread, the magnetized region is limited to a very narrow part of magnetic material 14 of magnetic pole 11, so that the recording density can be enhanced considerably.

Title: Sound signal recording system
Inventor: ARAFUNE YASUNARI
IPC: H04N9/82
Filed: 1982-03-01
Abstract: PURPOSE:To reduce the beat interference at reproduction and to make the beat on a reproducing screen inconspicuous, by recording sound signals after superimposing it on a low frequency converted chroma signal and a luminance FM signal. CONSTITUTION:At a frequency band between band CB of a chroma signal separated from a video signal and frequency-converted into a low frequency and a band YB of a luminance FM signal separated from the video signal similarly and FM-modulated, the sound signal is FM-modulated and recorded after being superimposed on the low frequency converted chroma signal and the luminance FM signal. Taking a horizontal synchronizing signal as fH, and m, n as natural numbers, and a carrier frequency of the low frequency converted chroma signal as fH(2n+1)/4, the carrier frequency of the sound FM signal is selected as fH(2m-1)/4 and (m-n) is selected as an even number. Thus, the interference between the luminance FM signal and the low frequency converted chroma signal is made less.

Title: Multi-channel access system for mobile radio communication
Inventor: KAWABATA FUMIO
IPC: H04W72/08
Filed: 1986-02-15
Abstract: PURPOSE:To efficiently utilize an assigned ratio line by utilizing an idle line so as to transmit/receive a control signal to/from a base station and a mobile equipment thereby applying the storage and acquisition control of the idle line. CONSTITUTION:The central processing section 5 of a base station retrieves an idle line in assigned radio lines during standby. That is, the central processing section 5 sends the 1st radio line code to a PLL oscillation circuit 11 and operates a front end section 2. When a reception signal is inputted to the front end section 2 from the reception antenna 1, a modulation signal is fed to an idle line detection section 4. When the modulation signal is fed to the idle line detection section 4, since its output level exceeds a prescribed threshold level, the central processing section 5 uses its output level to decide that the 1st radio line is connected already and in the block state and the 2nd radio line code is sent to the PLL oscillation circuit 11. The operation above is repeated and when the 4th radio line is idle, the transmission is sent for a prescribed time from the transmission antenna 10 via the line.
