Recently, 40 W fluorescent lamps with 32 mm tube diameter are replaced with 32 W one with 26 mm in diameter to conserve lamp materials and to increase luminance efficiency. Moreover, 35, 28 and 14 W fluorescent lamps with 16 mm in diameter (T5), which are nowadays developed, also may replace 32 W lamps again. Application of slim lamps, however, requires(More)
In this study, in order to develop the low temperature sintering ceramics for multilayer piezoelectric transformer, PCW-PMN-PZT ceramics doped with Li/sub 2/CO/sub 3/, Bi/sub 2/O/sub 3/ and CuO as sintering aids were manufactured, and their microstructural, dielectric and piezoelectric properties were investigated. When the only CuO was added, specimens(More)
