Abstract: A marker for detecting pancreatic cancer, said marker comprising a glycoprotein C4BPA or PIGR, whereby a pancreatic cancer patient can be distinguished from a chronic pancreatitis patient or a normal subject and thus specifically diagnosed. Also, the marker is usable in monitoring the postoperative prognosis of a pancreatic cancer patient. When the aforesaid marker is used in combination with another pancreatic cancer marker such as CA19-9, furthermore, a pancreatic cancer patient can be distinguished from a chronic pancreatitis patient or a normal subject and diagnosed more specifically.

Abstract: A reference point detection pulse generator determines normally-equidistant reference points which provide references over the whole control axis range of a numerically controlled machine. On the basis of the outputs of the reference point detection pulse generator and a moving amount detection pulse generator, the position of a moving part is numerically calculated by a moving part position calculator means. The position of the moving part based on the output of the moving amount detection pulse generator is compared with that based on the output of the moving part position calculator means, and if an error is present therebetween an alarm is issued.
