Title: Reception signal detection system
Inventor: FUKUDA SETSU
IPC: H04L27/00
Filed: 1990-10-11
Abstract: PURPOSE:To surely detect a reception signal at a low speed by using a signal detection use frequency different from a transmission frequency by a prescribed frequency to sample a reception signal repetitively. CONSTITUTION:A reception signal is compared with a threshold level at a comparator 21A and its output is fed to a protection circuit 23, then the signal is sampled in a timing of a multiple of, e.g. 7/8 of a transmission timing. When sampling is tried for 8 times, the level of the signal exceeds a threshold level Th at numbers 4-6, where number 1 is set to the leading of the signal. Thus, at least one sampling exceeds the threshold level Th for 6 samplings. The protection circuit 23 outputs a detection signal of the reception when the circuit 23 detects e.g. five times of the state in excess of the threshold level Th once for each of 6 samplings. A digital wave may be used for the comparator.

Title: Automatic assembling system for spot welding of galvanized steel sheet
Inventor: WATANABE TOUICHI
IPC: G06Q50/00
Filed: 1994-11-08
Abstract: PURPOSE: To maintain high productivity and to ensure quality assurance by estimating such number of spot welding or period as sufficient nuggets are no longer obtained, from a resistance value between electrodes for example, and thereby promoting adaptive control when the estimated value reaches a reference value. CONSTITUTION: When a welding current controller 19 starts, the valve and the regulator of a welding gun 24 are actuated, a welding part at the first spot of a panel 10a-10c is held between a pair of welding electrodes and pressurized by a set welding force. The effective value of a welding current for each cycle is calculated by the welding current controller 19, and the normality of the welding current is discriminated. For any irregular supply of electric current during continuous spot welding, the number of times is counted. Its frequency higher than the reference gives rise to the estimation that sufficient nuggets are no longer obtained under the same welding conditions; and hence, the number of spot welding or the period theretofore becomes the limit of the estimated value under the same welding conditions.  As a result, in order to increase the welding force from the next spot welding, the valve and the regulator are selected to return to the main routine, thereby execute stable welding.
