This disclosure relates to a hard coating composition, which includes a silazane compound, a thiol-based compound, a polyfunctional urethane (meth)acrylate having a cyclohexyl group, a photoinitiator, inorganic nanoparticles, and a solvent, and which can also exhibit superior scratch resistance, hardness and flexibility.

Hard coating composition, and hard coating film, window film and display device comprising the same

Described is a hard coating composition composed of a silazane compound, a polyfunctional (meth)acryl-based dendrimer compound or a polyfunctional urethane (meth)acrylate having a cyclohexyl group, a photoinitiator and a solvent, and to a hard coating film, a window film, and a display device including the same, thus exhibiting superior scratch resistance, hardness and flexibility.

A head drum assembly for a tape recorder includes a stationary drum, a rotary drum, a magnetic head installed in the rotary drum for scanning a traveling magnetic tape, and at least one vibration absorbing unit installed in the stationary drum for absorbing vibrations associated with the traveling magnetic tape. The head drum assembly absorbs vibrations via a vibration absorbing element elastically biased to protrude toward the outer circumferential surface of the stationary drum by a spring installed in an opening of a portion of the stationary drum such that the vibration absorbing element makes contact with the magnetic tape. As the vibration absorbing element makes contact with the traveling magnetic tape, it gives appropriate tension to the magnetic tape to dampen any vibration created therefrom.

A smear noise eradication method in a charge-coupled device (CCD) type camera comprises the steps of inputting respective image signals from one pair of CCD image pick-up devices whose lengthwise directions of corresponding vertical CCDs are perpendicularly disposed with respect to each other, and which are installed on an optical path, and eradicating smear noise after comparing the one pair of image signals according to corresponding pixels. Using the one pair of CCD image pick-up devices, the image signals of the CCD image pick-up devices are compared with each other. When the smear noise is generated, it is eradicated to obtain a high quality image signal.
