His innovative work focuses on enhancing the efficiency and accuracy of A/D converters and differential pressure transmitters.
Latest Patents
One of Shimakata's latest patents involves a measurement instrument that utilizes two A/D converters. These converters share a common power supply voltage and sample A/D conversion values at both short and long time intervals. By maintaining both A/D converters in a constant active state, or continuous conversion mode, the total consumption current remains stable. This stability ensures that the power supply voltage is regulated, resulting in reliable A/D conversion values from each converter.
Another notable patent is for a differential pressure transmitter. In this invention, when the damping time constant Dτ is adjusted to Dτ=0, the sampling period Ts is automatically modified from 100 ms to 50 ms. Consequently, the sampling time is also reduced from 60 ms to 30 ms. This allows the processing unit to sample an electrical signal corresponding to the pressure difference detected by a differential pressure sensor every 50 ms, without performing a damping operation. The processing unit then calculates the measurement value ΔP of the differential pressure through various operations, including linearization and square root calculations.
