Latest Patents

Owashi’s listed patent, “Heating and Cooling Unit,” describes a system that selectively heats or cools a set of dies using circulating oil. In heating mode, a first pump moves oil from a reservoir through a flow-direction changeover valve and a check valve to a second pump. The second pump sends the oil through an oil heater and into fluid paths in the dies. Oil leaving the dies returns to the second pump, forming a closed loop that circulates heated oil.

In cooling mode, the changeover valve directs oil toward the dies, and oil discharged from their fluid paths passes through a switching valve to a heat exchanger before returning to the reservoir. This arrangement enables the unit to switch between heating and cooling operations.

Career Highlights

The available information associates Owashi with Toshiba Machine Co., Ltd. His listed invention addresses temperature control in die systems through separate heating and cooling flow arrangements.
