Title: Gallium arsenic field effect transistor oscillator
Inventor: KOTANI MICHIO
IPC: H01P7/04
Filed: 1981-11-28
Abstract: PURPOSE:To ensure the variation of frequencies over a wide range and at the same time to secure the stability of the oscillating frequency with a dielectric resonator having high Q, by connecting a coaxial resonator containing a variable capacitance diode to the dielectric resonator. CONSTITUTION:A gallium arsenic FET2 contains a dielectric resonator 7 which forms a gate or a feedback circuit from the gate to the drain and a coaxial resonator 11 which is connected coaxially to the resonator 7. The FET2 has oscillations, and the magnetic flux and the electric field leak partially to the upper part from the resonator 7 on the basis of a resonance mode. These leaked- out magnetic flux and electric field are connected again to the resonator 11, and this connection can be controlled by the coaxial, form, dimensions, etc. Therefore the resonance frequency can be changed by changing the capacitance of a variable capacitance diode 14 which is set inside the resonator 11. At the same time, the oscillating frequency can be varied over a wide range by increasing the degree of connection to the coaxial coupling part. Furthermore the high stability is obtained by using the resonator 7 of high Q.

Title: Method for recording, reproduction and erasing optical information
Inventor: OTA TAKEO
IPC: G11B7/24
Filed: 1987-08-03
Abstract: PURPOSE:To attain erasing and recording simultaneously with a single spot laser light by providing a means to modulate the power level of the laser light, setting the power level at the level or more, to make a recording member into a liquid phase condition at an erasing level, and setting the power level at the level to make the member into a crystalization transfer temperature or more in a solid phase condition at a recording level. CONSTITUTION:The modulation power level of the laser light is selected into a high power level 8, low power level 9 and a reproducing power level 19, and the modulation laser light is radiated to the same track 10. Parts 14, 15, 16 and 18, to which the low power level is irradiated, are crystalized, blackened, and go to the mark of a recording signal. In such a case, since the part of a crystalization recording signal mark 13 receives the irradiation of the high power level 8, the part fuses, returns to an amorphous condition 17, and the signal mark is erased. The low power level 9 is radiated to the section 12 between signal marks, and a crystalizing signal mark 16 is newly formed. Thus, the information can be recorded and erased with a single approximately-circular spot.
