Title: Innovations by Toshitaka Semma
Introduction
Toshitaka Semma is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of image forming technology, holding a total of seven patents. His work focuses on enhancing the efficiency and functionality of image forming devices.
Latest Patents
One of Semma's latest patents is an image forming device designed to supply DC power to a load from both a main power supply device and a capacitor supply device. This innovation allows stored DC power to be supplied to a load after returning to a normal-power mode or during the power-up of an image forming device. The auxiliary power supply does not supply the stored DC power to the load, while the main power supply provides both AC and DC power if a predetermined processing is performed upon starting the device. Additionally, the auxiliary power supply supplies the stored DC power based on the elapsed time and environmental conditions.
Another significant patent is for an image forming apparatus that includes a chargeable capacitor. This apparatus features a main power unit that outputs a first DC power and an auxiliary power unit that outputs a second DC power. The auxiliary power unit contains a rechargeable capacitor, and a measuring unit assesses the performance of the capacitor. If performance insufficiency is detected, a control unit adjusts the use range of the capacitor accordingly.
