Abstract: A heat generator comprising a quartz tube containing an electric resistor and a catalyst coating layer comprising at least active alumina, silica and a platinum group metal, formed on the surface of the quartz tube can heat a material to be heated and the catalyst coating layer itself because of the catalyst coating layer being provided on the surface of the quartz tube. The catalyst coating layer surrounds the quartz tube and thus efficiently absorbs heat from the electric resistor by radiation and heat conductance, whereby the catalyst coating layer can be heated to the activation temperature within a short time. Furthermore, the heat generator also heats air around the heat generator to circulate the air as a convection air stream around the heat generator.

Abstract: The present invention has an electrode for energization use of a thermal head having an unprecedentedly new electrode construction of a full peripherally surrounding type, so that one heating portion corresponds to one individual electrode without separation or independence of a heating resistor. Thus, the heating efficiency in the printing operation is improved to increase the thermal response property, thus making it possible to save the power. Furthermore, the full periphery surrounding electrode portion is adapted to be completely covered by the heating resistor to remove the dispersion of the resistance values of each dot responsible for the dispersion of the printing width of the heating resistor, and to completely provide uniformity by an energization overload trimming system.

Abstract: This invention relates to a sealing glass for use in bonding glass, ceramics and metals and specifies the composition of a sealing glass which is workable at moderate temperatures and is excellent in transparency and strength. Amorphous magnetic materials have themselves a crystallization temperature and when used in a magnetic head, the amorphous materials undergo crystallization in assembling the head at a sealing temperature higher than the crystallization temperature and becomes not only brittle but also deteriorated in magnetic characteristics so that the head becomes unsuitable for use. The present glass is advantageously used in such a case.
