摘要： A joining equipment in which a neural network is employed for controlling a joining process. A dynamic analog model is used for neuron elements configuring the network. The equipment includes a detector, a controller, and a neural network. The detector detects a joining state of a joining portion when work pieces are joined with each other. The controller controls the output of the joining equipment. In response to output signals from the detector, the neural network transmits signals to the controller. Such a structure allows the joining equipment to flexibly respond to complicated changes in joining states. Besides, using similarity with a thermal conduction equation enables to minimize the number of input items fed into the neural network. Furthermore, using an approximate solution to the thermal conduction equation realizes to accelerate the time for numerical calculation without loss of accuracy.

摘要： An optical processing apparatus has high reliability and stable welding quality. In the processing apparatus, a semiconductor laser and an optical system are disposed to a flow path of processing gas. The gas protects the semiconductor laser and the optical system from moisture and dust while cooling them. In addition, the apparatus also leads the processing gas to flow through a holder of the optical system to increase cooling effect for the optical system and to improve an optical accuracy. The apparatus guides the processing gas along a surface of a cover glass inside a nozzle ejecting the processing gas to a workpiece, to prevent the surface of the cover glass from being damaged and stained. The processing gas is ejected in a direction coaxial with a direction of output light, so as to shield an area being processed.

摘要： A method for evaluating quality of a resistance weld is provided, in which a nugget generation state during a welding process is evaluated by observable numerical values based on physical phenomena, and which can afford a wide application range in welding material as well as a capability of accurate knowledge as to the nugget generation state of the weld. Based on that a specific resistance value of a metal material to be welded has a temperature dependency in a conduction state of AC or current-pulsated welding current, a rate of change of inter-chip dynamic resistance instantaneous value during a current changing period is determined, a changing state of the dynamic resistance instantaneous value is further calculated, and a heat-generating state of a weld zone, i.e., a nugget formation state is estimated. Thus, a quality evaluation of a weld is performed accurately.

摘要： An apparatus for controlling the resistance welding comprises a first operation for yielding an estimated condition value representing a state of nugget formation through the application of a thermal conduction simulation to welding part, a second operation for outputting a modification to welding condition based on the result of comparison between the estimated condition value and a predetermined standard condition value for forming a desired nugget, and an output for practically changing the welding condition of welding unit in accordance with the modification. Namely, the welding condition is kept controlled through the feedback of difference between a given standard condition value and an estimated condition value derived from simulation.

摘要： An image forming apparatus includes a belt, a detector, a determining section, a skew correcting section, and a storage section. The belt is stretched around rollers and provided with an index. The detector provides an output value. The determining section determines the index that is passing through the detection region on the basis of a change in the output value, the change exceeding a threshold. The skew correcting section performs control relating to skew correction of inclining the roller and correcting the position of the belt. The storage section stores the threshold having a value between the measured maximum amount of change in the output value when the skew correcting section inclines the roller at the maximum angle and the amount of change in the output value resulting from the index when the index arrives at or passes through the detector.
