    • At least one of a rise time and a fall time of a dielectric resonator oscillator are reduced. The dielectric resonator oscillator includes a dielectric resonator, a drive circuit for applying a resonance voltage to the dielectric resonator, a switch for applying a voltage required for generating the resonance voltage to the drive circuit, a switch for applying a ground voltage for stopping generation of the resonance voltage to the drive circuit, and a capacitor connected to a power terminal side that supplies a voltage, as seen from the switch, for removing noise generated by the drive circuit. If these switches are made conductive exclusively, oscillation can be stopped immediately by turning on the switch. Since the capacitor is in a charge storage state at all times, regardless of ON/OFF of the switch, the oscillation operation can be started immediately when the switch is turned ON.
    • 介质谐振器振荡器的上升时间和下降时间中的至少一个减小。 介质谐振器包括介质谐振器,用于向介质谐振器施加谐振电压的驱动电路,用于向驱动电路施加产生谐振电压所需的电压的开关,用于施加用于停止产生谐振电压的接地电压的开关 到驱动电路的谐振电压,以及连接到电源端侧的电容器,其从开关看,提供电压,用于去除由驱动电路产生的噪声。 如果这些开关是专门制造的,则可以通过打开开关立即停止振荡。 由于电容器始终处于电荷存储状态,与开关的ON / OFF无关,因此当开关接通时可以立即开始振荡操作。

    • For patterning a magnetic garnet layer formed on the surface of a non-magnetic garnet substrate, the magnetic garnet layer, an intermediate layer and a resist layer are formed in this order from the substrate side, the intermediate layer and the resist layer are shaped in the state of an island, and then the magnetic garnet layer is etched in a hot phosphoric acid solution, the intermediate layer being composed of a material which is more soluble in the hot phosphoric acid solution than the resist layer so that the etched magnetic garnet layer side face is formed as a gently inclined face and that a conductor pattern extending on both the non-magnetic garnet substrate and magnetic garnet layer surfaces can be formed without breaking, or a protective resist layer being formed on the reverse surface of the substrate so that the application angle of a magnetic field to the magnetic garnet layer surface can be accurately controlled.
