Title: Photomagnetic reproduction head
Inventor: NOMURA HIROO
IPC: G11B11/105
Filed: 1983-02-04
Abstract: PURPOSE:To attain the miniaturization and reduced electric power consumption of a photomagnetic reproduction head by detecting photoelectrically the Kerr revolving angle of the reflected light sent from a vertically magnetized recording medium through irradiation of the polarized and modulated light via a liquid crystal polarization element. CONSTITUTION:The laser light sent from a semiconductor laser 16 of a photomagnetic reproduction head is turned into parallel beams through a collimator lens 17 and then into the linear polarized light by a polarizer 18. This linear polarization is carried out with no generation of heat by a polarization modulator 19 using the chiral smetic liquid crystal. Therefore the polarization and modulation is possible in a small-sized constitution and reduced power consumption. Then detectors 24 and 27 detect photoelectrically the Kerr revolving angle of the reflected polarized and modulated light sent from a vertically magnetized recording medium 13, and the recorded contents are reproduced. In such a constitution, a photomagnetic reproduction head is miniaturized with reduced power consumption.

Title: Hole burning memory
Inventor: MURASE CHIKAO
IPC: G11B7/24035
Filed: 1991-02-12
Abstract: PURPOSE:To allow the holding of a memory at a higher temp. by using a medi um which is oriented in at least a part in a specified direction by impressing an electric field thereto as a medium to disperse light absorption centers. CONSTITUTION:Hole burning arises when the recording medium RM consisting of a fluororesin is cooled to about 4 deg.K and is irradiated with a laser beam of 693nm while an electric field of 2MV/cm is impressed thereto in the same direction as the direction at the time of poling. The hole slightly decreased in the area is detected when the absorption spectra are measured after the recording medium is heated up to about 100 deg.K under the impression of the electric field thereto, is held for about 30 minutes and is then returned to about 4 deg.K in this state. The possible cause thereof lies in the cooperative effect of the molecules by the external electric field or the effect of suppressing the thermal motion of the molecules. Consequently, the memory holding at about 100 deg.K is possible.

Title: Signal discriminating circuit of very wide band two-way communication high amplifier or the like
Inventor: NIITANI TOSHIMITSU
IPC: H03F3/62
Filed: 1985-02-01
Abstract: PURPOSE:To obtain a two-way communication machine having a very wide band, high sound quality and high amplification degree by forming a signal discriminating transistors (TRs) of which collectors are directly or indirectly connected to each other. CONSTITUTION:A parallel circuit consisting of an input part of receiving amplifier inputs TR7, TR8 and a constant current element FET2 is arranged between both the collectors of the signal discriminating TRsTR9, TR10. Since branching TR4, TR5 have emitter resistor R5, the input resistance is extremely high. Therefore, a transmitting current flowing from the emitter of a signal discriminating TR9 into the base is extremely low. Although a low transmitting signal voltage is also generated in the collector circuit, the voltage is interrupted and does not flow because its phase is reversed against that of a collector transmitting signal voltage of a signal discriminating TR10. Therefore, the transmitting signal is not leaked into the receiving amplifiers TR7, TR8 connected between both the collectors. On the other hand, a receiving signal inputted from a communication line L is extracted by a resistor R11.
