Abstract: A motor comprises: a stator core; an insulator coupled to the stator core; a coil wound around an outer surface of the insulator; and a terminal coupled to the insulator, wherein the terminal includes a coil coupling portion to which both ends of the coil are coupled, and the insulator includes a protruding portion which protrudes further upward compared to other regions and supports any one of both ends of the coil.

Abstract: Provided are a selective recovery method of vanadium and cesium from a waste sulfuric acid vanadium catalyst by a hydrometallurgical method including water leaching, solid-liquid separation, vanadium solvent extraction, vanadium selective stripping, and cesium alum production, and a high-quality vanadium aqueous solution and cesium alum produced thereby.

Abstract: Discussed is a pin push inspection connector that can include a first connector assembly having a front portion adapted to connect to a connector under test in a first direction and to be fixedly coupled to the connector under test; and a second connector assembly having a front portion connected to a rear portion of the first connector assembly in the first direction and provided so that a connection interval with respect to the first connector assembly is variably adjusted in the first direction or a second direction that is opposite to the first direction. The second connector assembly can include at least one inspection pin provided therein to be connected to at least one terminal pin provided in the connector under test.

Abstract: A network server for providing web pages to user terminals which access through user identifications (IDs) may include: a communicator connected to a network; and a processor configured to communicate with the user terminals through the communicator. The processor may be configured to score first convertibility points corresponding to the respective user IDs, according to whether actions of the user terminals on the web pages are matched with predetermined user events, select one of the plurality of message types according to whether the first convertibility point of one user ID among the user IDs is higher than a threshold value, when the one user ID accesses through a user terminal, and provide the selected message type including the selected object to the user terminal of the one user ID.

Abstract: The present invention relates to a waste battery treatment apparatus using continuous heat treatment, and a method for recovering valuable metals from lithium-based batteries using the same, the waste battery treatment apparatus comprising: a frame (10); a reaction reservoir (30) which is disposed in the inner space of the frame (10) and has thereinside a treatment space (S1) in which waste batteries to be treated are disposed; an inlet 34 (33) in which a gas blocking door (34) is disposed so as to selectively communicate the treating space (S1) with the outside, and which serves as a path through which an object to be treated is inputted to the treating space (S1) of the reaction reservoir (30). In addition, the waste battery treatment apparatus is provided with a vacuum forming means (40) which is connected to the treatment space (S1) of the reaction reservoir (30) to vacuumize the treatment space (S1).

Abstract: A rotor of a motor capable of improving durability of the motor by increasing a bonding force between a ring magnet and a resin. The rotor includes a ring magnet having an insertion hole passing through the center thereof, a shaft inserted into the insertion hole, and a resin that is disposed between the insertion hole and the shaft and fixes the ring magnet and the shaft. The resin extends to upper and lower surfaces of the ring magnet so as to cover at least parts of the upper and lower surfaces of the ring magnet.

Abstract: The present invention relates to a method of simultaneously recovering cobalt (Co) and manganese (Mn) from lithium-based BATTERY, and more particularly, to a method that is capable of simultaneously recovering cobalt and manganese from lithium-based BATTERY, i.e., recycled resources that contain large amounts of cobalt and manganese, with high purities using multistage leaching and electrowinning methods. According to the method of the present invention, cobalt and manganese can be simultaneously recovered from lithium-based BATTERY as recycled resources, and a recovery method that is cost-effective compared to conventional methods can be provided.
