Abstract: The present invention belongs to the field of chemistry, more specifically to the field of polymers. The present invention relates to a polymer nanocomposite for use in electrical and electronic equipment with properties suitable for applications such as electrical insulating and with thermal conductivity gain. The nanocomposite comprises at least one polymer matrix, at least one inorganic filler, at least one carbonaceous filler and at least one additive.

Abstract: In order to prevent any scratches from occurring at a back-end edge of a disk when a feeding roller finishes ejecting the disk and a user tries to grab and draw out the disk, a second ridge disposed on a side of an opening for inserting the disk of two ridges located on both sides of the feeding roller is made up of a straight part without any gradient for a specified range in a central part, a first tapered part with a sharp gradient within a specified range on both sides thereof, and a second tapered part with a gentle gradient on both sides further thereto. When the disk is drawn out for ejecting, only the back-end circumferential periphery of the disk point-contacts the first tapered part with a sharp gradient and accordingly it is possible to prevent any damage to the disk due to any possible line contact between the disk and the ridges.

Abstract: A problem that carriage of a disk by a feed roller cannot be smoothly accomplished depending on a type of the disk is to be solved. To achieve the object, the feed roller has an overall shape of expanding in diameter, and has floating roller parts movably fitted to a roller shaft in a central part and fixed roller parts pressed in and fixed in its two sides. A rotational force transmitted from a disk carrying motor causes a downward force to work on the feed roller through a roller gear. Even when a pressing force on the disk weakens, the fixed roller parts on the two sides can serve to carry the disk smoothly.

Abstract: The type of denomination of a coin inserted through a coin slot is discriminated by a coin discriminating section while the coin is being conveyed substantially horizontally by a mechanism for horizontally conveying coins, and the discriminated coin is distributed by coin distributing levers for selectively executing a first distributing operation for distributing coins to a relevant coin accumulating section and a second distributing operation for introducing the coins to an ensuing coin distributing section.
