With a total of 2 patents to his name, Nakayama's work reflects a commitment to enhancing the efficiency and safety of electrical systems.

Latest Patents

One of Nakayama's latest patents is an apparatus for controlling the starting of a three-phase load in its normal phase sequence. This innovative device is designed to connect to the load in a predefined manner and includes input terminals for receiving three-phase electric energy through external supply lines. The apparatus features a device that automatically corrects the phase sequence of the supplied electric energy. Additionally, it incorporates an open phase protection device that allows the load to start only when there is no open phase in the received electric energy. This ensures that the load operates correctly, even in the event of incorrect phase connections. In one embodiment, the apparatus is integrated into a submersible motor-pump assembly, ensuring that the pump always initiates its impeller in the correct direction for pumping.

Another significant patent by Nakayama is a submersible pump designed for civil engineering applications. This pump includes a wear-resistant protecting member positioned to shield the area opposing the backside of the impeller shroud from wear caused by abrasion from earth and sand in the liquid being handled. The protecting member is designed with holes that surround the exposed portions of the bolts, preventing direct contact with the liquid flow and thereby reducing wear on the bolts.
