摘要： A carrier for developing an electrostatic latent image, which carrier comprises core particles having formed thereon a resin coating layer, in which the resin coating layer comprises a fluorine-containing resin and a second resin having a softening point lower than that of the fluorine-containing resin, and the resin and the second resin each are partially exposed on the surface of said resin coating layer. The carrier may be produced by a process comprising the steps of: dry-blending core particles, a fluorine-containing resin, and a second resin having a softening point lower than that of said fluorine-containing resin; and melting the resin blend to coat said core particles. The carrier is excellent in stability with time and environmental changes, causes no adhesion, and is less consumed.

摘要： An entertainment system includes a digital television connected to a number of audio/video input devices. The television and at least two of the input devices support analog legacy communication schemes. The television is adapted to uniquely identify the analog output channels from each of the input devices. Uniquely identifying the analog output channels from each input device enables the television to automatically select the correct device output from among the numerous possibilities. This automation relieves the user of having to manually select the correct analog channel.
