Unreacted HF is removed with a gas scrubber wherein an alkali aqueous solution is preferably circulated and the treated NF3 is subsequently brought into contact with an aqueous solution containing Na2S2O3, KI, Na2SO3, etc., to remove OF2. The treated NF3 is passed through a heated and dehydrated zeolite layer to remove N2O and CO2 (0 to -125 deg.C and 0-5kg/ cm<2>G) and subsequently introduced into a collecting container cooled with liquid N2 to cool and liquefy the NF3. The thus purified NF3 is suitable as a dry cleaning gas for semiconductors, a cleaning gas for CVD devices.

The storage means 102 stores a program 102a, a data area 102b and information 102c to be displayed. The data area 102b is a variable to be used for the execution of the program 102a. At this stage, even when a cursor is moved within an area after the cursor is depressed when the cursor is outside of the area, a display area moves. Further, when the cursor is moved to the outside of the area in a state that the cursor is remained depressed, the moving of the display area is stopped. Thus, because an operation is determined by only the present status, an understandable operation can be executed.
