Title: Rotary arc fillet welding method using two electrodes
Inventor: SUGITANI YUJI
IPC: B23K9/127
Filed: 1986-08-28
Abstract: PURPOSE:To equalize the leg length of a welding bead by regulating the rotary speed and rotary diameter of the preceding and succeeding arcs in the prescribed range and by performing the movement control of each arc via the integral position operation of an arc voltage, etc. as well. CONSTITUTION:The rotary speed of an arc that the ratio of the vertical leg length l1 and horizontal leg length l2 becomes maximum is found to take N0. The rotary speed of the preceding arc is regulated to N0-120Hz and the rotary diameter is set in 1-6mm. The rotary speed of the succeeding arc is set to N0 and for the lower layer bead width WL the rotary diameter of the succeeding arc is limited to the range of WL+6mm from the larger part of WL-8mm and 1mm. The rotary direction of the succeeding arc is designated the right turn, etc. for the right vertical plate. In this way, the leg length of a bead is equalized because of the rotary speed of the succeeding arc being regulated to N0. The bead is moreover smoothed with the scooping-up effect of the welding metal.

Abstract: PURPOSE:To use a line in common for talking and data communication by connecting switchingly the line to a telephone set when a signal representing the data communication is not detected within a prescribed time after a bell signal transmitted from an exchange is detected so as to distinguish the incoming between the telephone set and data communication. CONSTITUTION:In case of the data communication, a bell signal 16Hz from the exchange 3 is detected by a bell signal detection circuit 43, its output signal drives a DC circuit closing relay 44, the line is held, a relay 41 is driven to switch a contact l1 to the position of data communication, and a timer 46 is set. After the timer 46 is set, an output signal is given to a terminal T1 after time T1. A center 1 starts a code transmitter 51 to transmit a prescribed data and a specific signal, the signal is detected by a detection circuit 50, the output signal is fed to the timer 4 before the time T1 for reset thereby preventing the line from being switched to the position of a telephone set 5. In case of talking by the telephone set, since no output signal is produced to the detection circuit 50 even after the elapse of the time T1, the timer 46 produces an output signal to the terminal T1 to activate the relay 41 and the contact l1 is switched to the position of the telephone set.

IPC: H01J37/304
Filed: 1982-11-15
Abstract: PURPOSE:To enhance the contrast between electrons reflected from a mark part, by a method wherein the lower layer part having an outer periphery which is constituted by a taper surface diverging toward the upper side thereof is made of a material smaller in number of reflected electrons than that for the upper layer part and is then covered with the upper layer part to form an alignment mark. CONSTITUTION:A lower layer part 7 having an outer periphery which is constituted by a taper surface diverging toward the upper side thereof is made of a material smaller than a metal material in number of reflected electrons. An upper layer part 8 covering the lower layer part 7 is made of a metal material which is large in number of relfected electrons. The upper and lower layer parts 8, 7 in combinatuon constitute an alignment mark 6. A resist 3 is applied on the surface of a substrate 1 formed with the mark 6. The mark 6 is detected by being scanned with an electron beam 4, thereby to effect alignment. In this case, the beam 4c applied to the upper layer part 8 is blocked by the metal layer and therefore is reflected from this region at a higher rate. Thus, when the mark 6 and its vicinities are scanned with the beam, it is possible to obtain an enhanced contract between detection signals.
