Title: Fe-co-mn-c alloy
Inventor: MIYOUGA OSAMU
IPC: C22C38/10
Filed: 1981-09-29
Abstract: PURPOSE:To obtain an Fe-Co-Mn-C alloy consisting of perscribed precentages of Co, Mn and C and the balance Fe and capable of being provided with desired magnetic characteristics by a short-time treatment under heating without requiring the strict control of the temp. dropping program and a long-time treatment under heating. CONSTITUTION:This Fe-Co-Mn-C alloy consists of, by weight, 30-55% Co, 15- 27% Mn, 0.3-20% C and the balance Fe. When the alloy is treated under heating at a temp. giving nonmagnetic gamma-phase in a thermal equilibrium state and quenched to room temp., the gamma-phase state is maintained without causing phase transformation. The alloy is not cracked even when cold rolled, cold swaged or cold drawn at a high rate, and it maintains the nonmagnetic state and has high workability. By simply treating the cold worked alloy under heating for a much shorter time (about 1hr) than the time of a treatment under heating for a conventional alloy, desired magnetic characteristics are obtd.

Filed: 1983-08-26
Abstract: PURPOSE:To improve the efficiency of an exchange program by detecting a dial pulse with a low-speed period program. CONSTITUTION:When a signal R attains an H, a call request is sent to the exchange program. When the signal R varies from the H to an L in a dial pulse detecting circuit while a signal E is at the H, a signal STB is held at the H through a circuit 3 to place a circuit 1 in a ready state, and the calculation of the circuit 1 is performed every time the signal R varies from the L to the H to output a dial pulse one after abother as parallel binary data to a signal group DP. A circuit 6 as a minimum pause detecting circuit operates after the signal R is sent by one digit of the dial pulse and a signal TM1 attains the H. The exchange program only detects the signal group DP when the signal TM1 is at the H, and the circuit 6 is so configured that the signal TM1 is at the H continuously for 250ms; the dial pulse detection program of the exchange program is only to detect the pulse with the program having a <=200ms period.

Title: Weld line profile control device
Inventor: SARUGAKU SHINICHI
IPC: B23K9/127
Filed: 1983-08-26
Abstract: PURPOSE:To improve a weld line follow-up property of a welding torch under the condition that stability of an arc is low, by detecting a quantity of electricity corresponding to the arc of the welding torch, and impressing the prescribed correcting quantity to a welding torch movement control device in accordance with a deviation to a reference quantity. CONSTITUTION:When a welding torch 7 approaches from a desired distance or is separated in the direction of the Y axis against a weld line WL, a difference is generated between a set value of a setting device 25 and an integral value of a Y axis integrator 26, and a comparator 29 detects a deviation. Subsequently, basing on the deviation, a Y axis servo-motor YS adjusts a distance in the direction of the Y axis of the welding torch 7 and sets the deviation to zero. Also, when the center of a weaving pattern is shifted to one of the left or the right against the weld line WL, a difference is generated in an integral value between left and right integrators 27, 28. As a result, a comparator 30 detects a deviation of both of them, driving of an X axis servo-motor XS is controlled by a detecting value, and the weld line WL coincides with the center position of the weaving pattern.
