    Abstract: A PTC composition comprising at least one polymer, from 5% to 45% by volume of electrically conductive or semiconductive particles having a room temperature electric conductivity of at least 10.sup.2 [s/m] dispersed in said polymer, and from 0.2% to 20% by volume of thermally conductive particles having a room temperature electric conductivity of no more than 10.sup.-3 [s/m] and a thermal conductivity of at least 20 [w/m.multidot.k] dispersed in said polymer. A PTC device using such a PTC composition has a high ratio of peak resistance to room temperature resistance, and exhibits high safety.

    Abstract: A magnetic recording apparatus for recording two kinds of mutually different information signals on independent tracks of a magnetic tape comprises first through fourth rotary magnetic heads. The third and fourth heads are mounted on a rotary body at positions respectively in vicinities of the first and second heads along a rotating direction of the rotary body. The height positions of the third and fourth heads on the rotary body are different from the height positions of the first and second head. An extremely narrow guard band or no guard band is formed between two adjacent tracks recorded with the same kind of information signal. On the other hand, a wide guard band is formed between two adjacent tracks recorded with different kinds of information signals.

    Abstract: A magnetic recording apparatus for carrying out a recording by selectively using one of two kinds of recording systems comprises first through fourth rotary magnetic heads, a first circuit for producing an FM luminance signal, second and third circuits for producing first and second frequency division multiplexed signals, and a switching circuit. The first and second heads are mounted on a rotary body at mutually opposing positions, and have the same height position. The third and fourth heads are mounted on the rotary body at mutually opposing positions respectively in vicinities of the first and second heads along a rotating direction of the rotary body, and have the same height position. The switching circuit selectively supplies the output signals of the first and second circuits to the first through fourth heads when a luminance/color separation recording system is selected as the recording system, and selectively supplies the output signal of the third circuit to the first and second heads or to the third and fourth heads when a low band conversion color recording system is selected as the recording system.
