20120212814 | TRANSMITTED LIGHT SELECTING DEVICE, THREE-DIMENSIONAL IMAGE DISPLAY DEVICE, AND THREE-DIMENSIONAL IMAGE DISPLAY METHOD - A transmitted light selecting device includes a first light selecting unit ( | 08-23-2012 |
20140112758 | High Temperature Components With Thermal Barrier Coatings for Gas Turbine - The most principal feature of the present invention is as follows: Namely, in the gas-turbine-use high-temperature component including the thermal barrier coating and a cooling structure, micro passages are provided inside an alloy bond-coat layer and a thermal-barrier ceramic top-coat layer of the thermal barrier coating, the micro passages being in communication from the substrate side to the surface side. Moreover, a partial amount of coolant of a coolant for cooling the high-temperature component is caused to flow out to the outside of the high-temperature component via these micro passages. The employment of the structure like this makes it possible to expect the implementation of a high-temperature component's heat-resistant-temperature enhancement effect based on the transpiration cooling effect. | 04-24-2014 |
