Latest Patents

One of Shigeta's latest patents is a transmission measuring system with high time resolution. This system includes a subject for transmission measurement that outputs an output signal in response to a start signal from a central processing unit. The system features an analog-digital converter that transforms the output signal into digital data. The central processing unit processes this data to determine the transmission time required for signal propagation. Additionally, a clock signal source provides a clock signal to the central processing unit, while a variable delay unit allows for the adjustment of the clock signal's delay time relative to the start signal for measurement.

Another significant patent is the transit-time difference type ultrasonic flowmeter. This device consists of a pair of ultrasonic transducers mounted on a flow tube, one at the upstream side and the other at the downstream side. It includes a switching device that alternates the operational mode of each transducer between transmitting and receiving. The flowmeter also features an amplifier for signal amplification and data reduction equipment that includes an analog-digital converter and a digital signal processor. This processor analyzes voltage-time data sets to estimate zero-cross points and determine the time required for wave propagation.
