Title: Ryuichi Fujimoto: Innovator in Radiation Imaging and Power Supply Technologies
Introduction
Ryuichi Fujimoto is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the fields of radiation imaging and power supply technologies. With a total of 16 patents to his name, Fujimoto's work has had a substantial impact on modern technology.
Latest Patents
One of his latest inventions is a radiation imaging apparatus that determines the timing of sampling and holding. This apparatus includes a pixel array with multiple pixels designed to detect radiation. The controller within the device obtains radiation generation conditions related to a radiation-generating apparatus during fluoroscopic imaging. It determines the timings of various sampling and holding operations in each pixel based on these conditions. Notably, the timing of at least one operation occurs during the irradiation period of radiation. Each pixel features a conversion element that transforms radiation into an electrical signal, along with a sample and hold circuit that samples and holds signals multiple times according to the timings set by the controller.
Another significant patent is for a power supply circuit that includes a DC-DC converter and a regulator. This circuit has a first node and a second node, with the DC-DC converter generating an output voltage based on an input voltage supplied from the first node. The regulator, connected in parallel to the DC-DC converter, controls the output current flowing to the second node based on a reference voltage that is lower than the input voltage.
