Title: Control method for continuous rolling line
Inventor: YAMAZAKI TOSHIYUKI
IPC: B21B37/00
Filed: 1988-03-22
Abstract: PURPOSE:To optimally control by computing the necessary time for the setting calculation of the outlet side installation of the line and for the setting operation and performing this setting calculation based on the line data on this side from the outlet side installation of the line by the line traveling distance in said necessary time. CONSTITUTION:A notation t1 is denoted as the timing when the point A on a strip 1 passes through the 1st stand 3, t2 is denoted as the timing when the point A passes through the last position just in time for starting the setting calculation and t3 is denoted as the timing when the point A arrives on the outlet side installation 6. T1 is the time between t1 and t3 and obtained by dividing the distance to the outlet side installation 6 of the line by the traveling speed of the strip. The time T2 required for the setting calculation and setting operation is obtained by a equation using primary smoothing, learning for each steel sort of the strip and path schedule respectively. T3 is the time subtracting T2 from T1 and at the time t2 after the time T3, the setting calculation is started. By this method, the setting calculation of line outlet side installation is performed using the latest data to optimally control.

Title: Electric resistance welding method using energy beam in combination
Inventor: MINAMIDA KATSUHIRO
IPC: B23K26/21
Filed: 1983-04-14
Abstract: PURPOSE:To prevent generation of a cold junction, penetrator, etc. and to perform sure welding in the stage of using a high-frequency voltage and a laser beam in combination in welding wedge shaped welding surfaces by controlling the incident angle, beam diameter, diverging angle, etc. of the laser beam. CONSTITUTION:The wedge shaped ends 2 of a tubular body 1 formed by forming a steel plate into a pipe shape are heated by the current conducted to contactors 4a, 4b from a high-frequency power source 4. On the other hand, a laser beam LB is radiated from a laser oscillator to said part to heat and melt the ends thereby welding the same. When the beam LB adjusted in a beam diameter D and a diverging angle alpha by beam shape converters 6, 7 and an objective mirror 8 is projected toward the single Vee groove, the laser beam is multiple-reflected by PL1-PR1 to form a final heating zone Hz and a melt zone Mz. The projecting angle between the beam LB and the inside surface of the single V groove increases sharply when the number of reflection increases. The position of the zone Hz and the zone Mz is thus controlled by changing the angle alpha.

IPC: G06F11/22
Filed: 1988-03-18
Abstract: PURPOSE:To effectively perform aging by executing the instruction of the next address when a jump instruction or a standby instruction appears in executing a built-in program. CONSTITUTION:The aging is performed by operating a one chip microcomputer in an aging mode by connecting to a power source and a clock. An instruction 14 just behind the jump instruction 13 is executed next to a test instruction 12 even when the built-in program includes a loop waiting input, and the one chip microcomputer is prevented from entering an input state. In case of including the standby instruction in the built-in program, an instruction Q22 at the next address is executed. The built-in program is executed sequentially from an execution start address to the final address without generating branch. By constituting a system in such a way that an operation is returned to an initial address after executing the final address of a ROM, it is possible to continue the execution of a various kinds of instructions in the period of the aging. In such a way, effective aging can be performed profitably.
