Abstract: Disclosure relates to an ink storage apparatus with a rotating type ink storage pouch. The ink storage apparatus storing ink to supply the ink to an ink-jet head includes a nozzle ejecting ink includes an ink pouch configured to store ink to supply the stored ink to the ink-jet head, an airtight casing connected to a gas pressure control system, a pouch holding part configured to hold the ink pouch while the ink pouch is inclined at a predetermined angle, and a pouch rotating part configured to rotate the pouch holding part on a predetermined rotating shaft to agitate the ink stored in the ink pouch, wherein the gas pressure control system is configured to control gas pressure of an internal space of the airtight casing, thereby allowing the ink stored in the ink pouch to maintain the meniscus state thereof at the ink-jet head.

Abstract: A display device is disclosed that includes a substrate, a display portion, a conductive layer, an inorganic layer, and an amorphous silicon layer. The substrate includes a first area including a transmission area and a non-transmission area adjacent to the transmission area, and a second area adjacent to the first area. The display portion is disposed in the non-transmission area and the second area on the substrate. The conductive layer is disposed between the substrate and the display portion, and overlaps the non-transmission area and the second area. The inorganic layer is disposed on the substrate under the conductive layer, in contact with the conductive layer, and overlaps the conductive layer. The amorphous silicon layer is disposed on the substrate, under the inorganic layer, in contact with the inorganic layer, overlaps the conductive layer in the first area, and entirely overlaps the substrate in the second area.

Abstract: The present disclosure provides a moving robot including a body which forms an appearance, a traveler which moves the body with respect to a traveling surface in a traveling area, a sensing unit which acquires environment information of the traveling area, and a controller which sets a parameter tailored to the traveling area according to the environment information and performs pattern traveling of the traveling area. Accordingly, even when information on an environment in which the moving robot is installed is not obtained from a manufacture in advance, the moving robot can directly obtain information on the corresponding environment and set an optimum parameter according to the environment to increase efficiency.

Abstract: A cutting apparatus includes: a stage on which is disposed a preliminary stacked body from which a cut stacked body having an edge is formed; a cutting unit movable along a first direction corresponding to an extension direction of the edge of the cut stacked body and with which the preliminary stacked body is cut to form the cut stacked body; a first detaching unit movable in a direction forming an acute angle with the first direction and including a first detaching tool which contacts the cut stacked body in detaching of the cut stacked body from the carrier substrate; and a second detaching unit movable in a direction parallel to the first direction and including a second detaching tool which is inserted between the cut stacked body and the carrier substrate in the detaching of the cut stacked body from the carrier substrate.

Abstract: An inkjet printer configured to control the temperature of ink discharged from nozzles of an inkjet head is proposed. The inkjet printer includes: an inkjet head including a plurality of nozzles configured to discharge ink, an ink reservoir configured to store ink supplied to the inkjet head, a supply channel configured to supply the ink in the ink reservoir to the inkjet head, a pressure control device connected to the ink reservoir through a pressure control tube and configured to maintain the meniscus of the ink injected into the inkjet head, and the ink temperature control unit configured to control temperature of the ink discharged from the inkjet head.

Abstract: Proposed is a method of forming an electrode on a surface of an object by using inkjet printing, the method including forming a buffer on an outer edge of an electrode formation position, and forming the electrode by filling electrode ink inside the buffer, wherein the buffer formation is performed by stacking buffer layers formed by inkjet printing of buffer ink, and hydrophilicity of a surface of each of the buffer layers is lower than hydrophilicity of the object surface. According to an electrode forming apparatus, the buffer constituting the outer edge of the electrode is formed high and the electrode ink is filled inside the buffer to form the electrode, thereby enabling the formation of the electrode having an increased sectional area.

Abstract: Proposed is a multi-needle head. The multi-needle head includes at least one adapter mounted with a needle in which liquid is discharged therethrough, and includes a holder in which the adapter is fixed. An O-ring having an outer diameter thereof larger than a width of a body of the adapter is coupled to the body of the adapter, a fixing hole into which the body of the adapter is inserted is formed in the holder, and an O-ring fixing portion having an inner diameter thereof larger than an inner diameter of the fixing hole is formed in the middle of the fixing hole such that the O-ring is positioned at the O-ring fixing portion. A vertical width of the O-ring fixing portion is larger than a vertical width of the O-ring, thereby allowing a height of the adapter that is fixed to the holder to be adjusted.

Abstract: Disclosed are a composite sintered body for a cutting tool and a cutting tool using the same. The composite sintered body for a cutting tool has enhanced heat conductivity and electrical conductivity to be strong against abrasion by heat and impact and to be capable of minimizing an influence on an edge during an Electrical Discharge Machine (EDM) operation.
