Abstract: An apparatus and method for inspecting a charging system of an electric vehicle are provided. The apparatus and method inspect the charging system to determine whether the charging system of the electric vehicle on an electric vehicle assembly line operates without error. In particular, a communication section within the electric vehicle is inspected based on a controller area network (CAN) communication, while charging currents are gradually increased, and the subsequent charging parameter curves and waveforms are monitored.

Abstract: There is provided an automatic sequential sampler for roof-top runoff of rainwater, which comprises: a sensing part, a controlling part and a sampling part, and more particularly, which takes samples of rainwater, at regular intervals, by sensing whether it rains and controlling the rotation and stop of a sample bottle shelf in the sampling part, using a timer and a counter.

Abstract: There is provided an apparatus for injecting a tracer within a groundwater observation well, which is capable of sequentially performing a tracer test by depth by injecting the tracer to a predetermined depth within the groundwater observation well. More particularly, the present invention relates to an apparatus and method for instantaneously injecting a tracer to a groundwater well, whereby opening and closing of a container receiving the tracer is controlled by using a pneumatic cylinder and the tracer on the ground is supplied to the container, so that the tracer is repeatedly carried and injected to a specific depth in a well.

Abstract: The present invention relates to a framed dartboard in which a magnetic rubber pad is combined with a case member of a picture frame that can provide interior decorations for the dartboard. The framed dartboard comprises a case member forming an outer case of the framed dartboard, a printed plate at least partially enclosed within the case member and containing designs related to a dart game, a magnetic rubber pad disposed at a rear side of the printed plate for attaching a magnetic dart, an elastic member disposed at a rear side of the magnetic rubber pad to absorb an impact force by the magnetic dart, a back plate which is disposed at a rear side of the elastic member, and a hanger portion for attaching the framed dartboard to a suitable external structure.

Abstract: Disclosed is a dart device having multi-purpose function, wherein a front rotated dart plate is rotatively connected to a dart support plate and additionally has a rear housing member functioning as a pencil case or a savings box. For this, a dart device having multi-purpose function comprises a dart support plate guiding the rotation of the front rotated dart plate in case that the dart is installed to a wall of a desk and used, the front rotated dart plate rotatively connected to the front of the dart support plate and having various designs for dart game, and a support member inserted in a plurality of support holding units formed on a rear surface of the dart support plate for supporting the dart support plate so that the dart device is installed to a desk.

Abstract: Disclosed is a multipurpose hanging picture, wherein in case that generally used hanging pictures are connected in plurality, they can be connected and separated easily. For this, the multipurpose hanging picture comprising: a printed hanging sheet on which pictures, paintings, targets or dart games are printed; a hanging rod detachably coupled to one side or both sides of the printed hanging sheet; an advertisement unit mounted to the hanging rod and functioning as an advertisement; a hanging cap mounted to both ends of the hanging rod and supporting it; and a hanging wire coupled to the hanging caps and stopped by it. And said hanging rod comprises at lease one locking slit provided on an outer surface of the hanging rod, a reinforcing rib formed inside the hanging rod to support it, and at least one locking groove provided concavely on the outer surface of the hanging rod so that the advertisement unit can be detachably attached.

Abstract: The present invention relates to a dart board assembly which makes a front dart board positioned on a rear board rotate smoothly while preventing separation due to the vibration from rotation of the front dart board. The front dart board includes a flat panel; a central shaft rearwardly protruding at the center of the flat panel, an inner stepped portion stepped at the inner diameter of the central shaft to a predetermined depth, and an engaging recess formed at the center of the central shaft for engaging a screw spike. A connection shaft is formed with a plurality of stepped portions including a proximal stepped portion inserted into the inner stepped portion of the central shaft, an intermediate portion supported by the inner diameter portion of the rear board, a distal stepped portion stepped and coupled to the inner diameter portion of a ball bearing, and a through hole formed at the center so that the screw spike can be passed through.

Abstract: The present invention relates to a framed dartboard in which a iron rubber sheet is combined with a case member of a picture frame that can make an excellent effect on interior decoration.

Abstract: The present invention relates to a dartboard rotating apparatus that makes a rear dartboard and a front dartboard rotated smoothly while making them not separated due to vibration occurring at the rotation of the front dartboard. The front dartboard 30 includes: a peripheral projection 31 being protruded at the periphery of the back of the front dartboard 30; a central axis 33 being protruded at the center of the front dartboard 30 to conform to the center of the circumferential recess 24 and guiding rotation; an inner stepped portion 37 being stepped at the inner diameter of the central axis 33 to a predetermined depth; and an engaging recess 35 being formed at the center of the central axis 33 for engaging the screw spike 50.
