    • The present invention provides an isolated switch-mode power supply device capable of sufficiently reducing power consumption in a standby mode. An isolated switch-mode power supply device includes: a capacitor that supplies control power for controlling switching of a switching element; a first control unit that includes a constant current supplying unit that controls switching of the switching element; a switching element that connects or disconnects the first control unit and the capacitor; a capacitance element unit having a capacitor to which a constant current is supplied from the constant current supplying unit, a capacitor charge voltage of the capacitance element unit changing according to an outputted voltage in the standby mode; and a second control unit that controls power supply to the first control unit by closing or opening the switching element during a switching pause period in the standby mode according to the capacitor charge voltage of the capacitor.

    • As a sealing composition which can seal a panel and a funnel of a color CRT at a relatively low temperature for a relatively short time, a non-crystallizing sealing glass essentially consists of PbO--ZnO--B.sub.2 O.sub.3 --Bi.sub.2 O.sub.3 --CS.sub.2 O system and has a thermal expansion coefficient of 80 to 95.times.10.sup.-7 /.degree.C. The sealing glass can be used as a mixture with 40 to 5 volume percent of refractory filler powder. The PbO--ZnO--B.sub.2 O.sub.3 --Cs.sub.2 O system glass consists essentially of, by weight, 65-80% of PbO, 5.5-8% of B.sub.2 O.sub.3, 3-9% of ZnO, 7-22% of Bi.sub.2 O.sub.3, 16% or more of ZnO +Bi.sub.2 O.sub.3, 0.2-1% of SiO.sub.2, 0.3-2% of Fe.sub.2 O.sub.3, and 1.5-4.5% of Cs.sub.2 O. The refractory filler is at least one element selected from tin oxide, lead titanate, and zinc silicate.
    • 作为密封组合物,其能够在相对较短的时间内在相对低的温度下密封彩色CRT的面板和漏斗,非结晶密封玻璃基本上由PbO-ZnO-B2O3-Bi2O3-CS2O体系组成,并且具有热 膨胀系数为80〜95×10-7 /℃。密封玻璃可以与40〜5体积%的耐火填料粉末混合使用。 PbO-ZnO-B2O3-Cs2O体系玻璃主要由以下组成:PbO:65-80%,B2O3:5.5-8%,ZnO:3-9%,Bi2O3:7-22%,Bi2O3:16% ZnO + Bi2O3,0.2-1%SiO2,0.3-2%Fe2O3和1.5-4.5%Cs2O。 难熔填料是选自氧化锡,钛酸铅和硅酸锌中的至少一种元素。
