Latest Patents

One of Kimura's latest patents is a semiconductor pressure transducer. This innovative device comprises a circular diaphragm made of a single crystal semiconductor material. It features at least a first strain gauge element with a piezoresistance effect, formed by injecting an impurity into the diaphragm in a linear region parallel to a predetermined axis. Additionally, there is a second strain gauge element, also with a piezoresistance effect, which is formed by injecting an impurity in a direction perpendicular to the axis. The design ensures that the distances between the strain gauge elements and the center of the diaphragm differ, enhancing the device's functionality.

Another significant patent is an apparatus for detecting misfire in multicylinder internal combustion engines. This apparatus includes a sound pick-up transducer located in the exhaust passage of the engine, aimed at detecting exhaust sound. It features an integrating circuit that synchronizes with the engine's rotation to integrate the electric output of the transducer. A comparison circuit then compares this output with a reference signal, allowing for the detection of misfires based on the comparison circuit's output.
