Abstract: Provided is an apparatus for checking a point of impact. The apparatus for checking a point of impact includes: a first supply unit configured to supply an object through rolling; a second supply unit configured to receive the object from the first supply unit through rolling and supply the object to a demand place; a variable unit configured to apply a tension force by pressurizing the object or release the tension force by releasing the pressurization based on a change in a position; a detection unit configured to detect the change in the position of the variable unit to generate position information of the object; a guide unit provided between the first supply unit and the second supply unit to guide the object; and a control unit configured to control a handling process including the supply of the object based on the position information of the detection unit.

Abstract: The present invention provides an apparatus for treating a substrate, the apparatus including: a head unit including a head formed with one or more nozzles that discharge a treatment liquid to a substrate; and a head maintenance unit configured to perform maintenance for the head, in which the head maintenance unit may include: a liquid receiving block formed with one or more liquid receiving parts having liquid receiving spaces with open tops; a decompression line fluidly-communicating with the liquid receiving space and configured to provide reduced pressure to the liquid receiving space; and a decompression valve installed in the decompression line.

Abstract: Multifunctional composite building materials, which are obtained by mixing nano silicon dioxide, nano titanium dioxide, nano aluminum oxide and nano zinc oxide with nano nickel-cobalt ferrite or nano nickel-zinc ferrite; surface active agent; air entrained agent such as diethanolamine lauryl sulphonate, protein extracts, pulp waste liquid, diatomite; “kumgang” medical stone; viscosifier such as hydroxyl ethyl cellulose and foam elimination agent such as tributylphosphoric acid ester or butanol in a certain ratio.

Abstract: Provided is an apparel production monitoring system using image recognition, including: a first camera module that takes an image of apparel products; and a monitoring device that analyzes the image of the apparel products to grasp the number and sizes of the apparel products, receives a transmission image of the apparel products, and compares and analyzes it with a previously learned transmission image to detect a defect of the apparel products.
