Latest Patents
One of Kitagawa's latest patents is a battery measurement system. This system includes a battery with terminals and a housing case, along with a battery measurement device. The device features a signal control unit that connects to the battery's external terminals and is designed to receive or apply an AC signal. Additionally, it has a response signal input unit that connects to the electrodes of the battery and is responsible for receiving a response signal to the AC signal. A calculation unit then processes this response signal to calculate complex impedance information. The design of the second electrical path is optimized to minimize the magnetic flux passage area, enhancing the system's efficiency.
Another significant patent is a fuel supply system. This system utilizes a sub-injector to inject liquid fuel into a vaporized-fuel chamber of a vaporized-fuel tank. The injected liquid fuel is vaporized within the chamber, and the resulting vaporized fuel is supplied to a combustion chamber through a vaporized-fuel passage. The supply of vaporized fuel is controlled by a purge valve, allowing for precise delivery to the engine at startup, which helps reduce emissions.
