Latest Patents

One of his latest patents is a sealing structure and method of manufacturing the same. This invention ensures a sufficient sealing property of a through hole. The sealing structure includes a cylindrically-shaped body part inserted into the through hole, formed of a thin plate of a first thickness. One end of the body part is open while the other end is closed. A tapered part connected to the opened end of the body part features a diameter that gradually expands outward as the distance from the body part increases. Additionally, a first bent part connected to the tapered part is formed of a thin plate thinner than the first thickness and is bent inward. This design allows a protruding part to elastically abut against the inner peripheral surface of the through hole.

Another significant patent is related to the stator core slot and pole piece arrangement for the stator structure of a rotary electric machine. This stator structure includes a cylindrical stator core with slots and pole pieces formed on the inner peripheral side, arranged alternately in a circumferential direction. A conductor segment, which is a conducting wire with a rectangular cross-section, is inserted into one of the slots through an insulator. This segment connects with another conductor segment similarly inserted in another slot to form a coil. Each insulator has a unique shape that includes a pair of opposite side surface portions connected with an intermediate portion along the wall surface defining the slot. The insulators are made of an insulating and elastic material, enhancing the overall functionality of the design.
