Abstract: An embodiment of the present disclosure provides a metal architectured plate with senses of tactile warmth and elasticity. According to an embodiment of the present disclosure, there is an effect that it is possible to provide a metal architectured plate with senses of tactile warmth and elasticity which is configured by stacking sheet-like metal architectured materials having micro-thickness with senses of tactile warmth and elasticity, the metal architectured materials including base microchannels formed with regular intervals; and microchannels with senses of tactile warmth and elasticity formed to protrude between the base microchannels, such that the base microchannels and the microchannels with senses of tactile warmth and elasticity form channels with senses of tactile warmth and elasticity, which are spaces for allowing control of thermal conductivity and an elastic modulus, thereby imparting human-friendly senses of tactile warmth and elasticity.

Abstract: Disclosed are a method of forming a seed layer on a high-aspect ratio via and a semiconductor device having a high-aspect ratio via formed thereby. Thus, efficient Cu filling-plating is possible, and plating adhesion of the seed layer to filling-plated Cu can be simply and profitably enhanced, thus imparting high durability upon forming metal wiring for electronic components. Moreover, stress of the seed layer can be lowered, thereby enhancing plating adhesion.

Abstract: The present invention relates to an exclusive alloy substrate material for CIGS solar cells. Particularly, the present invention provides a substrate material having a thermal expansion coefficient similar to that of a CIGS layer. The substrate material according to the present invention may prevent damage such as interlayer separation due to differing thermal expansion coefficients from occurring because the substrate material has a thermal expansion coefficient similar to that of the CIGS layer.

Abstract: The present invention relates to a controlled expansion flexible metal substrate material and to a production method therefor. In the present invention, an electrocasting method is used in order to produce a metal substrate material which comprises a controlled expansion alloy and has a textured structure and a wide width. Also, the flexible metal substrate material of the present invention can be used as the substrate for a silicon thin-film solar cell since the Fe—Ni alloying compositional ratio is controlled in such a way that the thermal expansion coefficient approximates that of silicon. The present invention is devised in such a way that the optical pathway is extended and the photoelectric conversion efficiency is improved since a textured structure is provided on the surface of a flexible metal substrate material by forming a textured structure on the surface of a plating drum used as a plating cathode or anode used in an electrocasting method.

Abstract: An optical disc drive, including a main frame a tray disposed such that the tray is to be inserted into or ejected from the main frame to load or unload a disc and a tray holding unit to press bias the tray, when the loading/unloading of the tray is completed, so as to restrict the vertical and lateral movement of the tray when the loading/unloading of the tray is completed.

Abstract: A disc may be inserted or ejected from a turntable of an optical disc drive without applying excessive force to the disc, and the disc is securely locked onto the turntable when the disc is being rotated. The optical disc drive includes a turntable having a protruding boss for insertion into a mounting hole formed on a disc. First locks are disposed at the outer circumference of the boss, such that the first locks can move in the radial direction of the boss to lock the disc located on the turntable. Elastic members provide an elastic force to the first locks. A magnetic member is disposed above the boss, and a second lock disposed in the boss increases a locking force of the first locks only when the second lock interacts with the magnetic member.

Abstract: An optical recording and/or playback apparatus in which a disc is prevented from being ejected from the optical recording and playback apparatus during operation of the optical recording and playback apparatus. The optical recording and playback apparatus includes a main body having an entrance, a deck mounted in the main body and having a spindle motor and an optical pickup unit, a tray mounted at the main body such that the tray is inserted into or ejected from the main body through the entrance, a loading unit to insert or eject the tray into or from the main body, and a safety door mounted at the entrance to close the entrance after the tray is inserted into the main body, the safety door being opened and closed according to the operation of the loading unit.

Abstract: An optical disk drive which decreases unit costs and reduces the size of a product. The optical disk drive includes a frame, a base chassis rotatably installed on the frame, a spindle motor and a pick-up device installed on the base chassis, a tray moving into and out of the frame when a disk cartridge is mounted on the tray, a loading device for operating the tray and the base chassis, and a disk cartridge recognizing device for sensing whether or not recognition holes formed through a disk cartridge case are opened or closed to display data of the disk cartridge. The disk cartridge recognizing device includes switches fixed to a front part of the frame, and a switch operating portion for operating the switches according to whether or not the recognition holes are opened or closed.
