Abstract: Provided is a gas turbine vane and blade assembly in which lattice structures are installed between an impingement plate and an effusion plate. The gas turbine vane and blade assembly is capable of enhancing cooling efficiency in an impingement/effusion cooling technique. In addition, the gas turbine vane and blade assembly can be manufactured using an additive manufacturing technique, and the lattice structures are capable of replacing supports that are used during an additive manufacturing process, and improving not only structural rigidity and stability but also cooling performance.

Abstract: An impingement cooling structure is provided. The impingement cooling structure includes a flow channel formed between a first wall and a second wall facing the first wall, a plurality of impingement cooling holes disposed in the first wall such that the plurality of impingement cooling holes are spaced apart from each other along the flow channel, and a flow diverter convexly protruding from a surface of the second wall in each space between injection axes of the plurality of impingement cooling holes.

Abstract: A touch sensor for a curved display includes: a first sensor including a) first sensor patterns arranged on a first flexible plastic substrate so as to be continuous in a first direction and spaced apart from each other by a predetermined interval in a second direction and b) first dummy patterns arranged between the first sensor patterns on the first flexible plastic substrate; a second sensor including a) second sensor patterns arranged on a second flexible plastic substrate so as to be continuous in the second direction and be spaced apart from each other by a predetermined interval in the first direction and b) second dummy patterns arranged between the second sensor patterns on the second flexible plastic substrate; and an adhering part causing the first sensor and the second sensor to adhere to each other.
