Abstract: A display device includes a first substrate. A transistor is disposed on the first substrate. A light-emitting element is connected to the transistor. An insulating layer is disposed between the transistor and the light-emitting element. A second substrate at least partially overlaps the first substrate. A color conversion layer is disposed on the second substrate. The insulating layer includes a first insulating layer and a second insulating layer. A distance between the first insulating layer and the first substrate is less than a distance between the second insulating layer and the first substrate. The first insulating layer includes a light blocking material.

Abstract: The present invention relates to the stabilization of an effective ingredient by using a mineral material. In the present invention, the effective ingredient can be stably supported using the mineral material, and a microcapsule obtained by the manufacturing method according to the present invention, when discharged to nature, causes no environmental problems due to encapsulation ingredients thereof being the same as soil ingredients, and thus can avoid micro-plastic issues.

Abstract: Disclosed herein is supporting structure for an offshore wind power generator. The supporting structure includes lower support part and main body part. The lower support part includes lower concrete part which is provided on a base installed on the sea floor and is reduced in width from the bottom thereto to the top, at least one lower hollow space which is formed in the lower concrete part, and a lower inner-pipe which is attached to the inner surface of the lower hollow space. The main body part is coupled to an upper end of the lower support part. The main body part includes a main-body concrete part, at least one main-body hollow space which is formed in the main-body concrete part and communicates with the lower hollow space, and a main-body inner-pipe which is attached to a circumferential inner surface of the main-body hollow space.

Abstract: A helical turbine power generation system is configured to generate electricity by using a helical turbine and an overload prevention generator. More specifically, the helical turbine is rotatably provided in a frame so as to continuously generate a rotation force under unidirectional or multidirectional fluid flow and a step-up gear is configured to increase the rotational velocity of the helical turbine up to a level required for generating electricity. Additionally, an overload prevention generator is incorporated to generate electricity by using the rotational velocity transferred from the step-up gear thereby preventing an overload caused by a sudden increase in the rotational velocity of the turbine.

Abstract: Disclosed is a helical turbine power generation system for generating electricity by using a helical turbine and a synchronous generator, the system including: a helical turbine rotatably provided in a frame so as to continuously generate rotation force under unidirectional or multidirectional fluid flow; a step-up gear for increasing a rotational velocity of the helical turbine up to a level required for generating electricity; a fluid coupling for preventing the rotational velocity increased by the step-up gear from increasing above a required velocity at a temporarily high rate of fluid flow; and a synchronous generator for generating electricity by using the rotational velocity transferred from the fluid coupling. Therefore, it is possible to reduce equipment costs and to prevent environmental pollution.
