20150315833 | DOOR CLOSER - Disclosed is a door closer of which the inside of a housing is made compact and thus is easily made smaller. The disclosed door closer is comprised so that movement of one end of a coil spring, which is relatively close to a link shaft, toward the link shaft inside of the housing is limited, and the other end of the coil spring, which is relatively far from the link shaft, moves toward the link shaft by being pushed by a piston base portion, thereby compressing the coil spring. | 11-05-2015 |
20150322705 | DOOR CLOSER PROVIDED WITH UNIT FOR ADDING DOOR-CLOSING FORCE - Disclosed is a door closer provided with a unit for adding door-closing force inside a housing. The disclosed door closer comprises a force-adding unit, which is included inside the housing, for adding the door-closing force. The force-adding unit comprises a cam which coaxially rotates with a link shaft inside the housing, and a cam pusher which is elastically compressed so as to come into close contact with the outer circumferential surface of the cam. The outer circumferential surface of the cam comprises an arc surface portion which is separated apart from a rotary axis of the cam at an equal distance, a concave surface portion which is separated apart from the rotary axis of the cam at a distance shorter than that to the arc surface portion, and one pair of protruding corner portions for connecting the arc surface portion and the concave surface portion. When the outer circumferential surface of the cam with which the cam pusher comes into close contact is converted from the arc surface portion to the concave surface portion due to the rotation of the cam, the rotational force of the link shaft is increased due to the elastic pressing force of the cam pusher. | 11-12-2015 |

20120288688 | SCINTILLATOR PANEL AND METHOD OF MANUFACTURING THE SCINTILLATOR PANEL - Disclosed is a scintillator panel, including a substrate, a scintillator layer formed on the substrate and including a plurality of columnar crystals so that radiation is converted into light at a predetermined wavelength, a dam structure formed on the substrate to be spaced apart by a predetermined interval from a peripheral edge of the scintillator layer, a protective layer formed on a surface of the scintillator layer, a surface of the substrate defined between the scintillator layer and the dam structure and a portion of a surface of the dam structure, a first coating layer formed on the protective layer to be disposed in a space between a peripheral surface of the scintillator layer and the dam structure, and a second coating layer formed on the first coating layer and the protective layer. | 11-15-2012 |
20140339330 | SOURCE GAS JETTING NOZZLE FOR A VACUUM DEPOSITION APPARATUS - Disclosed is a source gas jetting nozzle which includes a connection pipe having a portion connected to a source gas supplier, a first gas pipe including a communication hole communicating with the connection pipe by connecting to one end of the connection pipe and a first jetting hole, the communication hole and the first jetting hole being formed on the outer surface of the first gas pipe, and a second gas pipe including the first gas pipe inside the second gas pipe, and including a first insertion hole for inserting a predetermined part of the connection pipe to connect the one end of the connection pipe to the communication hole of the first gas pipe, and a second jetting hole for jetting the source gas introduced from the first gas pipe. | 11-20-2014 |
20140339331 | SOURCE GAS JETTING NOZZLE FOR A VACUUM DEPOSITION APPARATUS - Disclosed is a source gas jetting nozzle which includes a first gas pipe having one portion connected to a source gas supplier for supplying a source gas, including a first heater inside the first gas pipe, and including a first jetting hole formed on an outer surface of the first gas pipe, for jetting the source gas introduced from the source gas supplier, and a second gas pipe including the first gas pipe inside the second gas pipe, and including a plurality of second jetting holes formed on an outer surface of the second gas pipe, for jetting the source gas introduced from the first gas pipe. | 11-20-2014 |
