Title: Hajime Takada: Innovator in Ultrasonic Inspection Technologies
Introduction
Hajime Takada is a prominent inventor based in Chiba, Japan, known for his significant contributions to ultrasonic inspection technologies. With a total of 8 patents, Takada has developed innovative methods and apparatuses that enhance the reliability and efficiency of ultrasonic flaw detection.
Latest Patents
One of his latest patents is a method and apparatus for ultrasonic cross-sectional inspection. This invention prevents inspection omissions when ultrasonic flaw detection using a transducer array is applied to test objects being conveyed at high speeds. The method involves transmitting ultrasonic waves from a transducer array, receiving reflected waves, and converting these signals into digital waveform signals. It also includes transforming the timing between the digitalized signal data received by each transducer element based on the distances to spatially continuous focuses within the test object. The signals are then summed to provide a comprehensive inspection result.
Another notable patent is the ultrasonic method and apparatus for evaluating spot weld zones. This technology allows for the evaluation of the soundness of a spot weld zone with high reliability, even under limited measurement time. It effectively mitigates the influence of positional deviations and coupling conditions between the ultrasonic probe and the metal sheet. The method transmits ultrasonic waves from multiple positions outside the spot weld zone and evaluates the soundness based on the received waves.
