Latest Patents

One of Junichi Satoh's key patents is the "Arc scan ultrasonic transducer array." This invention features a plurality of transducers arranged successively on a common impedance matching layer made of resilient material. Each transducer consists of an elongated piezoelectric element that operates in a width expansion vibrational mode. The design includes a pair of electrodes attached to opposite surfaces of the element, along with an elongated block of impedance matching material positioned between the second electrode and the common impedance matching layer. The unique arch shape of the common impedance matching layer allows it to conform to the surface of a convex frame structure, enhancing the propagation of ultrasonic energy. The piezoelectric elements are strategically secured to the frame, bridging the parallel side members. This innovative arrangement enables focused ultrasonic energy transmission by selecting and energizing specific subgroups of piezoelectric elements during each clock interval, resulting in a linear shift of the subgroup with each successive clock pulse. The convex shape of the array allows for angulated energy transmission, providing an effective arc scan.
