Title: Shigeo Masai: Innovator in Infrared Detection and Amplifying Devices
Introduction
Shigeo Masai is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of electronics, particularly in the development of infrared detectors and amplifying devices. With a total of 3 patents to his name, Masai continues to push the boundaries of innovation in his field.
Latest Patents
One of Masai's latest patents is an infrared detector that includes a pyroelectric element, a first amplifier, and a second amplifier. The pyroelectric element features a first electrode formed on one surface of the pyroelectric body and a second electrode on the opposite surface. The first amplifier is connected to the first electrode, amplifying signals induced to it, while the second amplifier is connected to the second electrode, amplifying signals induced there as well.
Another notable patent is an amplifying device designed to set input impedance at several GΩ to several tens of GΩ, improving the ESD withstand current rating. This device connects an ECM to an input terminal, ensuring that frequency characteristics remain flat within the voice band due to the high input impedance of a CMOS amplifier. The input impedance is set at several GΩ to several tens of GΩ, which speeds up the response time after detecting a loud voice or turning on the power source of the ECM, achieving desired electrical characteristics. Additionally, a path for releasing surge voltage during assembly is constructed using P-channel and N-channel MOS transistors as ESD protective elements.
