Abstract: PURPOSE:To decide a specific area among those plural fault areas by holding the logical combination result of the 1st and 2nd fault detecting signals by an FF and resetting the FF with the reverse signal of the 2nd fault detecting signal. CONSTITUTION:An input signal 1 is supplied to a device 3 to be monitored through the 1st monitor circuit 2, and the output of the device 3 is monitored by the 2nd monitor circuit 4. When the signal 1 has no fault, a fault detecting signal (a) of the circuit 2 is equal to 0. If the device 3 has a fault under such conditions, the fault detecting signal (b) of the circuit 4 is equal to 1. An FF7 is set with the output 1 of a logical circuit 5, and the output signal A is equal to 1. Thus the fault of the device 3 is decided. When the signal 1 also has a fault, a=1 and b=1 are satisfied and the output B of a logical circuit 6 is equal to 1. Thus the fault of the signal 1 is decided. While the output of the circuit 5 is equal to 0. However, the FF7 is kept at 1 with A=1 secured as it is. Thus it is decided that the fault of the device 3 is kept as it is. When both faults of the signal 1 and the device 3 are recovered, a=0 and b=0 are satisfied. Then the FF7 is reset with the output of an inverter 8 to satisfy A=0 and B=0.

Abstract: PURPOSE: To facilitate an assembling and disassembling of a ram of an undetachable cam-type oil pressure cylinder as well as to prevent a damage to its sealing material, by forming a stopper with steel balls arranged in a ringlike channel at a head of the ram.  
     CONSTITUTION: In a part 28 of a small diameter, close to a head of a ram 23, is formed a ringlike channel 26 which constitutes a stopper with many steel balls 27 arranged therein, at a position of the maximum elongation of the ram.
