The present invention provides a device for protecting an antenna power circuit from overcurrent. A fuse and a positive thermistor are serially connected to an antenna power line, which is the output of the antenna power circuit, and power is fed to an antenna control cable via the power line. When overcurrent flows in the antenna power line due to a short circuit in the antenna control unit or due to another cause, the resistance of the positive thermistor increases and the electric current in the antenna power circuit is controlled before the fuse is melted. For this reason, the troublesome work of replacing the fuse is not required, and the system can be immediately restored from the abnormal state to its original state.

A thermochromic acrylic synthetic fiber comprising an acrylonitrile polymer in which a thermochromic pigment composition with an average particle diameter of from 0.5 &mgr;m to 30 &mgr;m is dispersedly contained in an amount of from 0.5% by weight to 40% by weight based on the weight of the polymer, and being made into fibers; the pigment composition containing (a) an electron-donating color-developing organic compound, (b) an electron-accepting compound and (c) a reaction medium that determines the temperature at which the color-developing reaction of the both compounds takes place. Also disclosed are a processed article of the above thermochromic acrylic synthetic fiber, and a process for producing the thermochromic acrylic synthetic fiber.

An offset printing machine having a blanket sheet wrapped around an outer circumferential surface of a blanket cylinder 3 so as to come in contact with a master and having clamps 29 and 30 for releasably retaining opposite ends of the blanket sheet to the blanket cylinder 3. After ending a printing operation, the blanket sheet is removed from the clamps 29 and 30 and dumped. Accordingly, the cleaning of the blanket cylinder 3 can be omitted to prevent hands and clothes from being stained.
