Abstract: PURPOSE: To provide a light source cathode in which a magnetic field works effectively on a  space in the hollow of a hollow cathode electrode when applied to the electrode incorporating a  Ni electrode offering a strong magnetic property which is composed of an alloy containing Ni  within a given range of atomic ratio and Cr and associated impurities for the rest.   
     CONSTITUTION: An alloy is prepared which contains 30 to 93% by atomic ratio of Ni with a  purity of 99.9% and Cr with a purity of 99.9% for the rest. Then, a hollow cathode with one  close end which is made of the alloy is sealed into a discharge tube and the intensity of light is  measured. The results of the measurement show that the alloy containing 30% by atomic weight  of Ni and 70% of Cr meets the requirement for the intensity of light, and the increase in the  content of Ni can satisfy the practical requirement of luminous intensity. In the range within  which the drop in the strength of magnetic field is limited with the application of external magnetic field, further meeting the required luminous intensity, the use of a cathode containing Ni  30% by atom minus the balance of Cr to Ni 93% by atom minus the balance of Cr can enhance  the effect of Ni light source used for the Zeeman atomic absorption analyzer.

IPC: B21B37/00
Filed: 1980-05-23
Abstract: PURPOSE: To diminish the level difference generated in the direction of longitude of a strip, and to improve the  yield of product, by detecting thickness and traveling distance of a material to be rolled and the number of rotation of a coiler, by inputting these detected data to an arithmetic processor which then produces a command signal for starting the slowdown and for starting the stopping action.  
     CONSTITUTION: The number of rotation of a coiler 2 is detected by a detector 20; the length signal for a strip 3  is taken out by a detecting roll 7 and a number of rotation detector 70; and the average thickness of the strip 3  and the level difference caused by the first rolling pass are taken out by a thickness detector 8. When the strip 3  running out of the coiler 2 is slowing down its speed at the first stage, each signal for the number of rotation of  the coiler 2, the average thickness of the strip 3, the rolling speed, and a position wherein a level difference is  caused by the first rolling pass, is inputted to an arithmetic processor 6 which then operates on the basis of these  input signals and constants, and produces a signal for starting the first stage slowdown. When a level difference  point caused by the first rolling pass comes to the position of thickness detector 8, the level difference detecting  signal, the rolling speed signal, the strip length signal, and the rolling direction signal are inputted to the arithmetic processor 6 which then operates these data and produces a signal to start the control for stopping action. By  this signal, the speed of rolling mill is reduced, and the level difference point caused by the first rolling pass stops just in front of the rolling roll.

Title: Welding current detector for arc welding machine
Inventor: YASUHARA YOSHIMICHI
IPC: B23K9/10
Filed: 1983-04-18
Abstract: PURPOSE:To discriminate inexpensively the presence or absence of welding current by disposing a magnetosensitive element in proximity to a cable in which the welding current flows, and detecting the change rate of voltage by the magnetosensitive element. CONSTITUTION:A magnetosensitive element 15 is disposed in proximity to a cable 10 in which the welding current of an arc welding machine flows. When the welding current does not flow in this state, the voltage VH between the terminals of the element 15 is set higher than the voltage V0 at the non-inversion input terminal of an operational amplifier 18 and therefore the output of the amplifier 18 is maintained on the low side and a relay 8 for detecting the welding current does not operate. When the welding current flows, the voltage VH between the terminals of the element 15 drops below the voltage V0 and the output of the amplifier 18 inverts so that a transistor 12 turns on and the relay 8 operates as well. The welding current detector is thus made smaller in size.
