The Japan Powder Metallurgy Association Award

Our development of powder cores for high-output rectangular-type ignition coils won the New Product Award (design section), while our planetary carrier for E-4WDs, employing the sinter brazing joint technique, won the Incentive Award at the 37th (FY2015) Japan Powder Metallurgy Association Awards.

Development of powder cores for high-output rectangular-type ignition coils
This award recognizes the technical novelties, such as the development of a combination of dies top and bottom, used to form a lengthy product, with high-lubricity coating on the inner surface, and wet forming processes. The award also evaluated the penetration into the market of magnetic steel sheets and the anticipated expansion of future production.

Our oil pump rotor won the Invention Incentive Award in FY2015 Kinki Region Invention Awards sponsored by the Japan Institute of Invention and Innovation. The awards are to honor those who perfected the excellent invention and contributed to the implementation, guidance, encouragement and training of invention in the Kinki region.

The award-winning invention this time is for the design of the tooth form of an oil pump rotor, which helps improve fuel efficiency in automobiles. Through this design, we were able to downsize the pumps and realize a higher discharge volume. Also, by further optimizing the rotor dimensions, we reduced the driving power of the pump (driving torque), further improving fuel efficiency, and reducing CO2 emissions.

The award recognizes that the technique is already being used in hybrid electrical vehicles, as well as its applicability to pump design in various non-automotive sectors and expectation of meeting societal needs of energy and resource savings.

60th (FY2015) Shibusawa Award

60th (FY2015) Shibusawa Award

Hiroshi Suzuki of J-Power Systems Corporation won the 60th (FY2015) Shibusawa Award from the committee for the memorial project to commemorate Dr. Motoharu Shibusawa’s winning of the award of cultural merit, Japan Electric Association.

The Shibusawa Award recognizes excellent achievements in ensuring the broad scope of electrical safety. Suzuki received the award as a member of the group that developed degradation diagnostic technology for terminal ends of CV cables*, together with Chubu Electric Power Co., Inc. and Tohoku Electric Power Co., Inc. Terminal ends used in a CV cable line that transmits high-voltage power gradually degrade over time. Suzuki’s team developed and popularized a technique to diagnose the degradation level by judging the acetylene concentration. The award recognizes the technique’s substantial contribution to fault prevention and maintenance of the cable terminal ends.

*CV cable is a cross-linked polyethylene (XLPE) insulated power cable.
