Title: Kazuya Ehara: Innovator in Ultrasonic Inspection Technologies
Introduction
Kazuya Ehara is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of ultrasonic inspection technologies, holding a total of 3 patents. His work focuses on enhancing the methods and apparatus used for ultrasonic inspections and flaw detections.
Latest Patents
Ehara's latest patents include an ultrasonic inspection method and an ultrasonic inspection apparatus. The ultrasonic inspection method involves outputting a pulse signal to an ultrasonic sensor to generate and transmit ultrasonic waves. These waves, reflected or scattered by an object, are received and converted into a waveform signal by the ultrasonic sensor. The waveform signal is then digitized to acquire waveform data. This method includes executing modulation processing to generate composite waveform data and demodulation processing to create compressed waveform data.
Another significant patent is the ultrasonic flaw detection method and apparatus. This invention identifies echoes appearing in flaw detection images by selecting and controlling combinations of transmitting and receiving elements. It records multiple waveform signals and extracts intensities based on the propagation time of ultrasonic waves. The method generates a flaw detection image that shows the distribution of totalized intensities, utilizing at least three sound velocities to calculate propagation times and produce multiple flaw detection images.
