    摘要： In a spark plug (100), the resistor composition constituting a resistor (15) contains semiconductive ceramic particles, offering a superior load life characteristic. Also, the value of (&agr;2−&agr;1)/&agr;1>=−0.30, where a value of electric resistance between a terminal (13) and a center electrode (3) is &agr;1 at 20° C. and &agr;2 at 150° C., so that deterioration of the radio frequency noise prevention performance at high temperatures can be effectively suppressed. The resistor composition contains semiconductive ceramic particles whose temperature coefficient of electric resistance shows a positive value, or a negative value of relatively small absolute value, (e.g., TiO2 particles having a rutile type crystalline structure, titanate or zirconate of alkali earth metal elements, titanium suboxide, etc.), or titanium metal. Thus, the invention provides a resistor-incorporated spark plug which is enabled to offer a stable load life characteristic even when a high load acts thereon, and which is unlikely to deteriorate in the radio frequency noise prevention performance even under high temperatures.

    摘要： A glaze layer formed on the surface an alumina-based insulator of a resistor spark plug contains SiO2 (18 to 35% by weight), B2O3 (25 to 40% by weight), ZnO (10 to 25% by weight), BaO (7 to 20% by weight), Na2O (3 to 9% by weight), and K2O (3 to 9% by weight). Since the difference between the coefficients of linear expansion of the glaze and that of the alumina-based insulating material is relatively small, the glaze layer is less susceptible to cracks and the like. Also, since the glaze has a softening point lower than that of conventional lead-silicate-glass-based glaze, the glost-firing temperature can be as low as 800° to 950° C. Therefore, even in the case where glost firing is performed concurrently with a glass sealing step, a center electrode and a terminal metal piece are less susceptible to oxidation. Further, even though the content of the alkali metal component is high, a good insulating performance is obtained so that excellent flashover resistance is attained.

    摘要： An electronic device corrects its device side time with a time correction information supplied from outside the device. The electronic device includes a reception section and a time correction section. The reception section receives the time correction information. The time correction section judges whether the information is received during any correction inhibiting periods of the device side time, then either discards the time correction information if it is received during the correction inhibiting periods, or corrects the device side time with the time correction information if it is received other than the correction inhibiting periods.
