Latest Patents

One of Hirata's latest patents is a **semiconductor pressure converter**. This device applies a drive voltage to a power supply end of a shearing type gauge formed at the strain generating part of a semiconductor diaphragm. The output voltage is amplified with an amplifier, and the zero point is adjusted by applying a bias voltage related to the drive voltage. The span is adjusted without interference to the zero point by changing the feedback voltage of the amplifier. This invention achieves linear compensation, temperature zero point compensation, and temperature span compensation without mutual interference.

Another significant patent is a **capacitive displacement transducer**. This transducer utilizes a self-excited oscillator circuit that includes a pair of differential capacitors with a movable electrode positioned between two outer electrodes. The oscillation frequency is counted by a counter, and the output level is reversed each time a certain count is reached. This design improves upon prior art by eliminating complex circuits, thereby increasing reliability, efficiency, and reducing size.
