摘要:
A plasma etching apparatus is provided which can prevent corrosion of an aluminum substrate constituting an etching processing chamber or an inside component thereof, thereby avoiding a reduction in productivity due to scattering of a sprayed coating. In the plasma etching apparatus, an anodic oxide film is disposed between a ceramic sprayed coating with excellent resistance to plasma, and the etching processing chamber and the inside component thereof made of aluminum alloy. The anodic oxide film has a thickness of 5 μm or less to have heat resistance.

A temperature-adjustment system for a vehicle includes temperature-adjustment passages and obtained by circularly connecting a battery, an inverter, a DC/DC converter, a traveling motor, and a pump that circulates the heat medium that adjusts temperatures by cooling/heating the heat generation elements, are provided. The temperature-adjustment passages and are provided with proportional valves that interrupt the flow of the heat medium and adjust the flow volume of the heat medium, an air flow-in part that introduces air into the battery temperature-adjustment passage, and a heat medium discharge part that discharges the heat medium from the temperature-adjustment passage to outside of the vehicle. The proportional valve, air flow-in part, battery, pump, and heat medium discharge part are preferably arranged in that order, and the proportional valve is closed and an air take-in valve and a heat medium discharge valve are opened.
