Title: Koji Hirota: Innovator in Infrared Ray Detection Technology
Introduction
Koji Hirota is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of infrared ray detection technology. With a total of 4 patents to his name, Hirota's work has advanced the capabilities of infrared sensing devices.
Latest Patents
Hirota's latest patents include an "Infrared Ray Detecting Sensor with Getter Partition." This invention features an infrared ray detecting element located in the cool chamber of a Dewar structure. The chamber is evacuated to a vacuum level, and a getter is arranged to maintain this vacuum. A partition is strategically placed to form a restricted passage, allowing gas communication while obstructing stray rays generated by the getter. This design ensures that stray rays are reflected multiple times, thereby dampening their impact on the infrared ray detecting element.
Another notable patent is the "Infrared Rays Detecting Apparatus with Integral Temperature Control." This cooling type apparatus prevents fluctuations in infrared ray images caused by temperature variations. It includes a dummy element that mimics the structure of the infrared ray detecting elements. By detecting temperature variations through resistance changes in the dummy element, the output of the infrared ray detecting device is compensated, resulting in high-quality infrared images.
