Abstract: PURPOSE:To prevent the generation of the plastic deformation of the lead tube so as to obtain good dynamic characteristics of a sodium lamp by providing sodium amalgam in the luminous tube made of transparent alumina provided with the lead tube mainly made of niobium to which an electrode is fixed with titanium solder and by specifying the temperature of the titanium solder portion during the lighting of the lamp. CONSTITUTION:The temperature of the titanium solder portion of a lamp is to be kept between 756 deg.C and 825 deg.C. For instance, a luminous tube 1 is made of polycrystalline alumina and the lead tube 2 is made of an alloy of 90% of niobium and 1% of zirconium, and an electrode rod 5 is fixed to the tip of the lead tube 2 with titanium solder 4, and 6.0mg of sodium, 14mg of mercury and about 6.5kPa of xenon gas are sealed in the luminous tube 1. When a lamp with such a structure the rating of which is e.g. 100V, 150W is lighted at 100V the mean color rendering index Ra is kept at 85, the color temperature is kept at 2500K and the surface tempera ture (at the point [a]) of the titanium solder is kept at 818 deg.C, and even when the lamp is lighted at 129V (at this time, the power is 162W, the temperature of the tita nium solder is 825 deg.C) the plastic deformation of the lead tube is not generated, and on the other hand, when the temperature of the titanium solder is lower than 765 deg.C the mean color rendering index Ra is reduced to less than 70.

For example, the picture elements at a part P1 are counted by a base picture element number counting means 805 to position all the three colors in the same range, and parts P1, P3 and P4 are counted because of repeat ink images and base parts of the count objects at fine intervals. Next, the count value of the means 805 is collated with the number of base picture elements in the objective paper money to be collated by a base picture element number collating means 806 and when they are coincident, a detecting signal is sent to a system control circuit. Then, an image formation stopping command is applied to a printer, and forgery copy is prevented.

Filed: 1988-09-20
Abstract: PURPOSE:To continuously synthesize a compound with an optional isotope composition by combining isotope separation with high isotope selectivity and large separation coefficient by using laser and compound synthesis utilizing laser light as a heat or energy source. CONSTITUTION:Laser light is radiated to a gas mixture of a gaseous compound containing a specific isotope (e.g., <10/11>BCl3) and F2 by a laser 13 in a radiation cell 4 so as to excite selectively <11>BCl3 and synthesize <11>BCl3F. Then, an intermediate product (e.g., <10>BCl3) is purified depending on the difference of physical properties such as vapor pressure between BCl3 and BCl3F. The purified <10>BCl3 is introduced into a bath 7, mixed with a reaction gas (e.g., B2H4, C2H4, and Ar), and then supplied to a cell 9. Here, the resulting gas mixture is irradiated with laser light by a laser 14 to react chemically and produce a product (e.g., B4C). HCl and H2 are separated and removed from the reaction product by filter, etc. A highly pure product (e.g., B4C) is thus prepared continuously and easily.
