摘要:
A method for manufacturing a metal halide lamp in which tungsten coils are made to have diameters wider than the outer diameters of electrodes, and to have a coil pitch sufficient to prevent molten quartz glass from entering therebetween; and after the tungsten coils have been fixed around the electrodes, the pitch of the tungsten coils on the sides of the electrodes which are nearest molybdenum foils is extended by dragging a part of the tungsten coils toward the discharge ends of the electrodes to fix it tightly around the electrodes. As a result, when sealing is performed with quartz glass bulb, gaps between the electrodes and the glass bulb are provided on the discharge sides of the electrodes, whereby it can be prevented to occur cracks in the quartz glass bulb due to the thermal expansion of the electrodes; and on the molybdenum foil sides of the electrodes, the quartz glass bulb contacts the electrodes, thereby preventing peeling-off and accumulation of sealed material.

The carbon dioxide membrane separation system in a coal gasification process contains introduction of a mixed gas of hydrogen (H2) and carbon dioxide (CO2) in a high temperature and high pressure condition generated through water gas shift reaction from a water gas shift reaction furnace, while maintaining the temperature and pressure condition, to a zeolite membrane module containing a zeolite membrane for removing carbon dioxide, thereby removing carbon dioxide and generating a fuel gas rich in hydrogen. The fuel gas rich in hydrogen in a high temperature and high pressure condition discharged from the zeolite membrane module is fed to a gas turbine of the power generation facility while maintaining the temperature and pressure condition.

A power-saving discharge lamp 1 wherein gap control material 6 is provided in a clearance between an internal bulb 2 and an external bulb 5, having a smaller thickness than the dimension of the clearance. Nonuniformity of the clearance between the both bulbs caused by difficulties in supporting the internal bulb 2 while welding the external bulb 5 is eliminated and a suitable clearance is automatically provided by the gap control material 6 to prevent degradation of the heat insulation effect.
摘要:
A method is provided for forming a color filter for a liquid crystal display apparatus which requires considerably reduced area on a transparent substrate for performing electrodeposition of the color filter. The method includes coating non-extended liquid crystal driving terminal portions with a protective film with a notch etched therein for exposing an end edge portion of the non-extended driving terminal; and coating the non-extended driving terminals with a transverse strip of conductive material to place the non-extended terminals into a conducting state.
