Latest Patents

One of Saikaishi's latest patents is focused on oscillators. This invention describes an oscillator suitable for use as a local oscillator in high-frequency apparatus. It comprises a voltage-controlled oscillator, a reference oscillator, and a phase detector that detects the phase difference between the oscillation frequencies of the two oscillators. The design includes means for filtering the output of the phase detector to produce a DC voltage and a phase synchronizing loop that feeds back the DC output to the voltage-controlled oscillator. Depending on the duty cycle of the reference oscillator, the oscillation frequency of the voltage-controlled oscillator can be synchronized with either an odd multiple or an integer multiple of the reference oscillator's frequency.

Another notable patent is for an apparatus designed for presetting receivers of the synthesizing type. In this method, the frequency division ratio of a frequency divider in a phase-locked loop is set according to the content of an up-down counter. A search signal and a write signal are generated to sweep the up-down counter, allowing the contents to be sequentially written into a memory device each time an intermediate frequency output is obtained. The up-down counter is then preset based on data read from the memory device, enabling the receiver to tune into the desired broadcasting station.
