X線発生装置真空度監視システムの試作 （8ビットパソコンの有効利用)

An used 8 bit personal computer is utilized for an instrument for continuous monitoring of the vacuum valuses of X-ray genrators. The interface board, programmable peripheral interfacial LSI, 8255A and some IC's for address decoding are assembled into a completed unti. The concept of the construction of this interface unti is profitable for the inexpensive layout of experimental laboratories.
