Filed: 1982-11-04
Abstract: PURPOSE:To make it possible to prevent the erroneous operation of a control system, by providing a means for stopping control operation when the correspondence of the output signal of an oxygen concn. detector and the oxygen concn. in gas to be detected is broken. CONSTITUTION:When a current I is flowed to an electrolyte 1 by a current controller 2, voltage V is obtained in a voltage detector 3. Oxygen partial pressures inside and outside a chamber 5 are respectively set to PV, PA. When the partial pressure outside a diffusion resistance body 6 is set to PM while coefficient D of diffusion is made constant and the current I is increased, the partial pressure PV in the chamber is lowered and the voltage V is increased. At this time, voltage V' is compared with a set value V0 by a comparator 10 while a current I0 obtained when the current I is controlled so as to equalize V, V0 by a current setting device 11 is detected by a current detector 4 and inputted to an operation treatment circuit 9 to enable the detection of the partial pressure PM corresponding to the oxygen concn. in gas to be measured.

Abstract: PURPOSE:To obtain a coil free from strip top marks, by retreating wrapper rolls while accurately catching an arriving time of the tip of a strip, in a method of retreating the wrapper rolls in conformity with the tip of the strip. CONSTITUTION:An arrival of a strip (sheet) S is detected by an accleration meter 1 of a pinch roll P1 placed at the prescribed point separated from a coiler, and at the same time, an arithmetic commanding device 10 starts to count the pulses of a generator 2.

Concurrently with said calculation, a geometrical length is calculated from the dimensions relating to arranged positions set in the device 10 and the number of revolutions of a material M outputted from a pulse generator 4 to obtain the difference between the geometrical length and L1. The time that the strip S passes through each wrapper roll is obtained, basing on the geometric length until said difference becomes zero, on the outer hand, the time required for moving the length of said difference is obtained, and then, the retreats of the wrapper rolls are maintained until the sum of both times terminates at least.
