Title: Production of gaseous nitrogen trifluoride
Inventor: ARITSUKA MAKOTO
IPC: C01B21/083
Filed: 1990-07-17
Abstract: PURPOSE:To prevent the inefficient opening and closing of a pump valve and to eliminate a troublesome and irrational work at the time of collecting and storing liquefied NF3 by previously removing solid N2O at the liquefaction temp. of gaseous NF3. CONSTITUTION:Although NF3 is produced by various processes, the gaseous N2O is entrained in any process. The entrained gaseous N2O is removed by natural or synthetic zeolite. The gaseous NF3 free of N2O is continuously collected in the form of liq., and the liquefied gas is drawn off by a liq. pump and charged to a cylinder. When the charging is continued, gaseous N2O is solidified in a collecting vessel, the solid intrudes into the valve of the liq. pump, however the inefficient opening and closing of the valve is prevented by the removal of gaseous N2O. Accordingly, all the NF3 in the collecting vessel is vaporized and drawn off, and the gaseous NF3 need not be again liquefied, collected and charged.

Abstract: PURPOSE: To preserve embryos in the absolutely perfect state for a long period of time by keeping embryos under the hypoxic conditions by coating the embryos with oil, then cooling the embryos and storing them at a temperature just above the threshold value of the low-temperature sensitivity of the embryos. CONSTITUTION: Embryos, for example, somatic cell embryos obtained from a suspension of undifferentiated cells or zygotic embryos obtained by dissection of mature seeds are coated with an oil (preferably liquid paraffin) in an amount of 0.02-0.5ml every embryo to keep them under hypoxic conditions. The oil transfers a very small amount of the outer oxygen to the embryos so that the oil may acts as a preservative and supplies the outer oxygen to the embryos in the minimal amount needed for survival. In addition, the embryos are cooled down to just above the temperature of the threshold value of the low- temperature sensitivity that the embryos can no longer grow (1-10 deg.C). Thus, they can be stored for 2-4 months and sustain the ability to grow their plantlets. Artificial seed is obtained by coating the above-stated embryo with a capsule.
