摘要:
A drive circuit for a flat display apparatus which may include organic EL devices is disclosed wherein the light emission characteristic can be set variously and the color adjustment can be performed with a high degree of accuracy with a simple and easy configuration. A plurality of candidate voltages from voltage dividing circuits are selected in response to original reference voltage setting data to produce original reference voltages, and reference voltages for digital to analog conversion are produced from the original reference voltages. For the original reference voltages at the opposite ends of the voltage dividing circuits, the voltages of production references are varied with rough adjustment data, and the other original reference voltages are produced with reference to the original reference voltages at the opposite ends by the voltage dividing circuits connected in series.

A process for producing metallic titanium includes forming metallic titanium fine particles by supplying liquid or mist titanium tetrachloride from above the surface of a reaction bath liquid containing fused magnesium and fused magnesium chloride in a reaction vessel to effect a reaction, wherein a circulating flow perpendicular to the bath surface of the reaction bath liquid is generated or extended just under the bath surface by imparting a stirring force to the reaction bath liquid so as to generate or increase an upward flow rate of the reaction bath liquid in at least part of the region at a depth of more than 100 mm below the bath surface.

An electronic apparatus is adapted to be used with a portable storage medium installed therein. The apparatus includes a mounting portion in which a unit for driving a portable storage medium is mounted. The mounting portion is constituted by a metal plate. When a storage medium is installed, an opening of the metal plate into which said storage medium is inserted is electrically connected between an upper portion and a lower portion thereof, so that the metal plate does not resonate with radio waves generated outside of the apparatus.

摘要:
An electron beam treatment device is provided for treating a substance located in a processing chamber which includes electron beam tubes arranged such that electron beam windows project into the processing chamber. The electron beam tubes are arranged such that an absorption dose of the entire treatment area of the substance to be treated has a given distribution. The electron beams emitted by the electron beam tubes are advantageously superimposed so that the absorption dose of the entire treatment area of the substance to be treated in shifted into a given distribution condition, and in which thus the entire treatment area of the substance to be treated can be treated as a whole without moving the substance to be treated.
