Abstract:
A structure for mixing different materials in a pouch container includes a spout main body provided with a spout hole through which mixture of first and second materials is exhausted; a cap removably coupled on an outer portion of the spout hole and storing the first material therein; and a seal member coupled to a lower end of the tube portion.
Abstract:
Provided is an accommodating device for accommodating a different type of material and opening an accommodating part via a main body. The accommodating part, which is sealed, is disposed around a container spout part and coupled to the container spout part in a discharge direction of a material contained in the container and includes a storage space having a separate storage function. While the main body is disposed around the container spout part coupled to the accommodating part and is coupled to the container spout part, the storage space disposed in the accommodating part is opened to perform a dropping and mixing process in a storage space disposed in the container.
Abstract:
Disclosed is a connection device to be coupled with a container neck in different standards for use. The connection device is formed with a mouth part at the upper side and a screw thread part at the lower side. The mouth part at the upper portion of the connection device is formed in a screw thread or other shape in the standard corresponding to a bottle lid, and the inside of the screw thread part is formed with a screw thread corresponding to the standard of the container neck. The screw thread is integrally formed or an elastic screw thread is additionally added for the coupling with the necks of a plurality of containers.
Abstract:
The present disclosure relates to an active sonar system including a transmitter; a transducer; and an impedance matching circuit, and a method of estimating an equivalent model parameter of a multi-mode transducer, wherein an electrical equivalent model parameter having a plurality of stages corresponding to each mode is estimated by estimating an individual mode impedance and a total mode impedance from multi-mode impedance data and obtaining an interference amount of adjacent modes, and an equivalent model modeled thereby for which an interference effect by a multi-mode is taken into consideration is used for the design of an impedance matching circuit to minimize actual model fabrication and effectively derive detailed design elements and the like, thereby allowing an integrated circuit design with peripheral electronic units for interfacing the sonar system.
Abstract:
The storage chamber for secondary material applicable to the discharging direction of contents stored in the container consists of body with storage space and inseparable operating section mounted around the globe. If above operating section moves up, opening and closing hole made or formed in the storage space of storage is opened and contents stored in the storage space is dropped and mixed with contents stored in the container. The mixed contents are discharged via a vent mounted on the top of operating section. A vent is not opened until the operating section is opened, and closing section of opening and closing hole is provided so that the opening and closing hole may not be not clogged after being opened.
Abstract:
Provided is an apparatus for controlling temperature of a black body. The apparatus includes a black body emitting radiant energy of infrared rays; a first Peltier element adjacent to the black body, the first Peltier element having a 1a surface and a 1b surface that selectively emit or absorb heat; a copper plate adjacent to the 1b surface; a second Peltier element adjacent to the 2b surface, the second Peltier element having a 2a surface and a 2b surface that selectively emit or absorb heat; a heat transfer member comprising a bent surface adjacent to the 2a surface, and an arm extending toward both ends of the black body to be adjacent to the both ends of the black body and a control unit controlling the 2a surface to emit heat when the 1a surface emits heat, and the 2a surface to absorb heat when the 1a surface absorbs heat.
Abstract:
The present invention relates to a polypeptide structure which can simultaneously deliver an antibody and a nanoparticle into cells, more specifically, to a polypeptide structure for intracellular delivery of an antibody and a nanoparticle, which comprises a nanoparticle-binding region, an antibody-binding region and a signaling capable of delivering substances into cells.
Abstract:
A non-aqueous electrolyte for a lithium secondary battery includes a lithium salt, a basic organic solvent including a carbonate-based solvent, and a halogenated diphenyl ether compound represented by Formula 1: wherein Y is —O— or —R1—OR2—, where R1 and R2 are the same or different, and R1 and R2 are a C1-C5 alkyl group, an alkenyl group, or an alkoxy group, and only one of the phenyl rings is substituted with a halogen X1, where n is equal to 1, 2, 3, or 4 and the halogens in di-, tri-, and tetra-halogen substitutions are the same or different.
Abstract:
A protein biosensor having increased signal intensity to sugar concentration and the use thereof. A fluorescent indicator protein is described, in which fluorescent proteins of different emission ranges are fused to both ends of a binding protein undergoing a conformational change due to binding of sugars, such that a change in the concentration of various sugars involved in intracellular metabolism, e.g., maltose, can be detected by measuring a change in emission intensities, caused by FRET (fluorescence resonance energy transfer). A method for detecting a change in the concentration of sugars using such fluorescent indicator protein is also described. The fluorescent indicator protein has excellent signal intensity enabling precision measurement of intracellular concentration of various sugars. In one implementation, high signal intensity fluorescent indicator proteins can be prepared from proteins otherwise used as biosensors, to enable them to be more widely useful.
