Patent JP-S60224308-A (JP)
Title: Local oscillator
Inventor: KUBO KAZUHIKO
IPC: H03B5/12
Filed: 1984-04-23
Abstract: PURPOSE:To perform a stable oscillation in all bands by providing a small- capacity capacitor between the emitter and the collector of an oscillating transistor and connecting or opening the capacitor in accordance with frequencies. CONSTITUTION:A positive voltage is impressed to a point D to turn on a diode 18 in case of VHF, but a negative voltage is impressed there to turn off the diode 18 in case of UHF. Then, a small-capacity capacitor 17 is connected between the collector and the emitter in case of VHF. The impedance viewed from the base side is negative because of the existence of the capacitor 17, and the stable oscillation is possible. Meanwhile, the diode 18 is turned off to release the capacitor 17 from between the collector and the emitter in case of UHF, and degradation of the oscillated output is prevented in this case. Thus, the stable oscillation is performed in all bands.

Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To lessen a burden of an inverter device and increase a charging accuracy. SOLUTION: A charger consists of serial resonance-type inverters INV1, INV2, transformers TR1, TR2 which boast the outputs of the inverters, rectifiers RF21 , RF22 which rectify the outputs of the transformers, a spare charging capacitor Cy which is charged by the rectifier RF21 , and a magnetic switch SIo which discharges the capacitor Cy and charges a charging capacitor Co. The inverter INV1 is operated with the switch SIo being in an off state and the capacitor Cy is charged by the rectifier RF21 and then the inverter INV1 is stopped and the switch SIo is turned on and the capacitor Co is charged from resonance current to the level Vcy. When Vco becomes equal to Vcy, the inverter INV2 is operated and Vco is finely adjusted.  Since the capacitor Cy can be charged by the inverter INV1 due to the presence of the capacitor Cy and the switch SIo even while the capacitor Co is being discharged, a burden of the inverter device INV1 can be lessened. And, Vco is finely adjusted by the inverter INV2, so a charging accuracy can be increased.
