Latest Patents
Kiyobe's latest patents include innovative designs for microwave moisture sensors. The first patent describes a microwave moisture sensor that operates on the principle of microwave attenuation in resonance with water molecules. This sensor features measurement and reference signal systems that share a microwave oscillator, a detector, and other components. It includes a means for calculating the ratio of signals from the respective systems and an automatic gain control (AGC) circuit to maintain the reference signal at a predetermined level. This design enhances measurement accuracy by compensating for drifts in the microwave oscillator and detector. Additionally, the sensor measures the basis weight and temperature of the material, processing these values to achieve accurate moisture percentage readings.
The second patent outlines a microwave moisture sensor comprising a first transmission and reception system with horn antennas positioned opposite each other, and a movable sheet-like measurand in between. It also includes a second transmission and reception system that re-emits microwaves received by the first antenna against the measurand. The design ensures that the antennas are spaced appropriately to optimize measurement accuracy.
