Title: Optical head device for magneto-optical recording
Inventor: YAMANAKA YUTAKA
IPC: G11B11/105
Filed: 1987-07-22
Abstract: PURPOSE:To prevent the deterioration of a regenerated signal with a simple constitution by providing a beam splitter having a phase difference reverse to the phase difference of P and S polarizations generated at a total reflection mirror in an optical system to conduct reflected light to a photodetector. CONSTITUTION:The outgoing light from a semiconductor laser 1 is condensed through an integrated prism 20 onto a recording medium 6. A part of the reflected light of the medium 6 is reflected on the beam splitter in the prism 20, and inputted to the optical system for detecting polarization rotation. On the reflecting surface of the splitter, multilayer films to compensate for the phase difference of both the polarization are formed, the polarization plane of the reflected light compensated for the phase difference is rotated by 45 deg. at a 1/2 wavelength plate 7, and divided into P and S polarization at a polarization beam splitter 8. The reflected light is made incident on a photodetector 10 through a convergent lens 9, and the signal is regenerated by the output difference of the detector 10. Thus, the deterioration of the regenerated signal is prevented with a simple constitution.

Abstract: PURPOSE:To prevent the overflow and the underflow of a buffer memory of the receiver side and to improve the quality of the reproduced voice signal by synchronizing the voice sampling clock of the transmitter side with the voice reproduced clock of the receiver side. CONSTITUTION:A voice packet production circuit 1 turns the input voice signal into a packet through a clock generating circuit 2 and sends this packet to a packet transmitter circuit 4. A packet generation part 3 generates a clock synchronizing packet which is sent to a packet network through the circuit 4. Then a receiver circuit 5 sends a voice packet to a reproducing circuit 6 and the clock synchronizing packet to an average cycle time calculation part 7 respectively. The part 7 calculates the difference between the average cycle time of the received clock synchronizing packet and the transmitting cycle time of the clock synchronizing packet generated by the circuit 2. Then a dividing circuit 8 is controlled based on the preceding calculated difference so that a cycle equal to the voice signal sampling cycle of a device of the transmitter side is secured. Thus the synchronization is secured between the sampling clock of the transmitter side and the reproduced clock of the receiver side.

Title: Magnetic tape eraser
Inventor: FUKAZAWA TOSHIO
IPC: H01F5/00
Filed: 1983-10-03
Abstract: PURPOSE:To obtain an AC eraser of a low power consumption type by using an AC erasing head having an azimuth and then using a coil wound round the core of said erasing head as an oscillating coil of an oscillating circuit which supplies an erasing current. CONSTITUTION:The oscillation frequency of an oscillating circuit 36 is decided by a capacitor 45 and a coil 35 wound round a core 31 of a magnetic material having high permeability of an AC erasing head 46. The coil 35 functions as an oscillating coil and at the same time produces AC magnetic fields at gaps 33 and 34. Then the coil 35 impresses the AC magnetic fields leaked out of the gaps 33 and 34 to a magnetic tape and erases them. In this case, a remaining magnetization pattern obtained after erasion is reproduced by a reproducing head with an azimuth loss since the gaps 33 and 34 have azimuths. Thus the erasion frequency can be set within an audio band, and the impedance of the head 46 is lowered. Therefore the erasion power is also reduced. Furthermore the voltage impressed to the circuit 36 can be reduced less than the conventional level.
