Abstract:
A heterogeneous-substance accommodating device used by being coupled to a mouth of a container includes an accommodating part having a storage space disposed within a main body, a soft foldable part disposed on an upper portion of the accommodating part, and an opening part disposed on the bottom of the upper portion of the foldable part to lengthily extend downward. A different kind of substance is injected into the storage space of the accommodating part, and a lower portion of the accommodating part is sealed by using a sealing part. When the foldable part is pressed, the opening part breaks the sealing part so that the different kind of substance contained in the storage space drops into the container and is mixed. The foldable part is folded while being expanded outward when a force is applied to an upper portion of the foldable part.

Abstract:
Provided is an accommodating device for different materials, which includes a fixed part fixed around a container neck and an operating part disposed around the fixed part and coupled thereto. An accommodating part having a storage space extends downward within the operating part, and a lower end part and an outer ring-shaped part of the accommodating part are sealed by a sealing support part and a sealing part of the fixed part disposed around the container neck and coupled thereto. In the accommodating part, a tab for breaking perforations, which is formed on a lower end of the accommodating part of the operating part, breaks the perforations formed between the sealing support part and the sealing part when a consumer rotates the operating part. During this process, a protrusion part protruding from the upper side of the sealing part is pushed downward by a side protrusion piece of the operating part so that the different type of material stored in the storage space of the accommodating device falls into the container and undergoes a mixing process. The sealing support part disposed around the outer ring-shaped part of the accommodating part and coupled thereto and the sealing part formed inside the sealing support part are configured such that an inner ring-shaped part of the sealing part tightly contacts an inner wall part of the lower end of the accommodating part so as to maintain sealing force thereof.
Abstract:
A container for liquid, which discharges contents when the side surfaces thereof are pressed by the fingers. A coupling unit is assembled to the top of the container body so as to discharge the pressed contents. The coupling unit has an outlet comprising a check valve which opens/shuts by means of predetermined pressure. The coupling unit having the outlet is covered with a lid for protecting the outlet. The side surfaces of the container body have pressure adjustment surfaces that protrude inwardly. Predetermined gaps are maintained between the ends of the pressure adjustment surfaces and the side surfaces of the container body, located in front of the ends of the pressure adjustment surfaces.

Abstract:
Provided are a distributed analog phase shifter and a method of manufacturing the same, which reduce a change in a characteristic impedance while changing a phase velocity with respect to an applied voltage. In the distributed analog phase shifter, a coplanar waveguide (CPW) is formed in a line form on a substrate. A plurality of ferroelectric capacitors is periodically loaded to the CPW. The ferroelectric capacitors include a ferroelectric film in a pattern form and defines the ferroelectric film affected by the applied voltage within an area of the ferroelectric capacitors. Accordingly, the change in the phase velocity with respect to the applied voltage is maintained without the change of the CPW characteristic and a return loss characteristic and a total insertion loss are improved since a total dielectric loss of the ferroelectric film is decreased.
