Abstract: An electronic price indicator according to an embodiment includes a display displaying product information, an NFC module configured to communicate with a user terminal, a Bluetooth module configured to communicate with the user terminal, and a processor configured to control the display to display the product information received from the user terminal through the Bluetooth module. The processor is further configured to release a sleep mode when receiving an interrupt from the user terminal through the NFC module, and perform Bluetooth communication with the user terminal by initiating a scan for a predetermined period of time to receive an advertising signal from the user terminal.

Abstract: The present invention discloses an adhesive applicator for manufacturing a core, a core manufacturing apparatus, and an adhesive application method using the same. The adhesive applicator includes: a nozzle body having at least one adhesive outlet; and a nozzle plug movably provided inside the nozzle body in order to open/close the adhesive outlet. The adhesive outlet includes a nozzle hole for discharging the adhesive from the inside to the outside of the nozzle body, and the nozzle plug includes a plug body movably provided inside the nozzle body to selectively block the nozzle hole, and a plug tip formed to protrude on a fore-end surface of the plug body. The fore-end surface of the plug body has a flat surface which faces the nozzle hole and is orthogonal to an axis of the nozzle hole.

Abstract: Disclosed herein is a bonded type laminated-core member manufacturing apparatus comprising an adhesive applying unit which is selectively open for applying an adhesive to a material being continuously transferred, and a blanking unit sequentially forming laminar members having a predetermined shape by blanking the material, wherein the adhesive applying unit includes an adhesive applicator having an outlet channel for discharging the adhesive, and a valve closing the outlet channel and opening the outlet channel for discharging the adhesive when the material and the outlet channel come close to each other. since an outlet of a nozzle is opened only when a material approaches an adhesive applying unit and close when the material separates from the adhesive applying unit, leakage of the adhesive prevent can be prevented and the discharge time and the application amount of the adhesive may be regularly controlled.
