Latest Patents

Yoshioka's latest patents include an innovative oxygen concentration or humidity controlling apparatus. This device features an oxygen concentration controlling element where the shortest distance between the anode and cathode, separated by a solid electrolyte film, is set not larger than 50 µm. This design accelerates the back-diffusion of water generated in the cathode to the anode, eliminating the need for a tank or pump to supply water to the anode. Additionally, the apparatus incorporates a photoelectric element positioned at an opening to the atmospheric air, allowing it to accumulate electric energy in a secondary battery. This results in a space-saving apparatus that can operate continuously even when the power is turned off, functioning both as a humidifier and a dehumidifier.

Another notable patent is a cooling device for power semiconductor switching elements. This boiling type cooling device utilizes an aqueous solution of ethylene glycol as a cooling medium. It includes an evaporator, a condenser, and a vapor and liquid return pipe. The design ensures that the lowest portion of the condenser is positioned higher than the top surface of the cooling medium in the evaporator, with the bottom surfaces of the condenser tilted downward toward the top end of the liquid return pipe. Furthermore, a pump is integrated into the liquid return pipe to drive the cooling medium back to the evaporator.
