Title: Power source
Inventor: NISHIMURA KOJI
IPC: H05B41/24
Filed: 1985-05-27
Abstract: PURPOSE:To prevent an erroneous operation by providing the second DC auxiliary power source for applying a DC voltage having a smooth rise before applying and combining the DC voltage of the first DC auxiliary power source to the output voltage of a full-wave rectifier. CONSTITUTION:A discharge lamp firing device is composed of the first and second DC auxiliary power sources 1, 2 through a full-wave rectifier DB1, a high frequency inverter 4, a discharge lamp tube voltage detector 5 and a controller 6. In this case, the power source 2 is constructed to vary the output voltage by a transistor Q5. Thus, before the DC voltage of the power source 1 is combined with the output of the rectifier DB1 by the power source 2, the slope of the rise of the voltage is always applied to a smooth DC voltage. Thus, a voltage having rise shorter than a reverse recovery time is not applied to the diode.

Abstract: PURPOSE:To obtain a ferroelectric thin film having the sufficient insulation withstand voltage regardless of its thinness by putting a TiO2 monocrystal substrate in the powder of lead oxide (PbO), heating it, and forming the ferroelectric (PbTiO3) thin film on the surface of the substrate. CONSTITUTION:An MgO crucible containing TiO2 monocrystal and lead oxide PbO is put in an electric furnace and heated to convert the surface of the TiO2 monocrystal into a PbTiO thin film. That is, the side where PbTiO3 is to be formed is mirror-polished with a TiO2 (rutile) monocrystal plate 3 and spatter- etched, on the other hand, the PbO (litharge) powder 4 is used, the temperature of the electric furnace 5 is increased, and the PbO gas is generated to be reacted with the TiO2 plate 3. If the temperature of the electric furnace is 800 deg.C or higher and the flow quantity of oxygen gas 7 is 200cc/min (core tube 6), the portion of TiO2 with the thickness of 100mum becomes PbTiO3. A ferroelectric thin film thus obtained has high density, a large current collecting coefficient, a flat surface, and it is made thinner.
