Latest Patents

Kashiwase's latest patents include innovative apparatuses that utilize ultrasonic waves for flaw detection. One of his notable inventions is a flaw detection apparatus employing tire probes that measure the thickness of a test object or the position of a cavity inside it. This apparatus employs a pair of ultrasonic probes, and by changing the relative position of one probe to the other, a plurality of waveform data of ultrasonic reception signals is acquired. Each of the acquired waveform data is added together, minimizing the level of the surface wave component through the addition of the waveform data. This method effectively offsets the shifted phase caused by differences in arrival times, leading to more accurate flaw detection.

Another patent by Kashiwase focuses on a similar flaw detection apparatus that also employs ultrasonic waves. This invention measures the thickness of a test object or the position of a cavity by acquiring waveform data of ultrasonic reception signals. The addition of the acquired waveform data per corresponding unit of time further enhances the accuracy of the measurements.
