In a decentralized control system, a program of the system is described in one form to flexibly cope with changes of the system, and the program developing efficiency, processing performance, and reliability of the system are increased. In configuration, a plurality of control processors and a plurality of devices are connected to a network, the control processors connected to the network are automatically detected and there is determined program execution assignment to possibly equalize the processing load imposed on the control processors. Each control processor executes the program in accordance with the program execution assignment.

Decentralized control system for network connection

A contents distribution system for a simulation ride system has a seat rocking unit, a video unit, an acoustic unit, and a simulation ride control apparatus. The simulation ride control apparatus has the simulation ride system controlling operations of the seat rocking unit, the video unit, and the acoustic unit by using content data, and a distribution apparatus for a ride contents administration center. The distribution apparatus for the ride contents administration center distributes the content data and the simulation ride control apparatus receives the distributed content data.

A method and an apparatus for grasping surface mounted devices such as an IC or the like by the hand of the robot and automatically and accurately loading them onto the contact pattern of a printed circuit board by means of an image processor are disclosed. According to this method, a measurement line is provided onto each image pattern of the pin array of the surface mounted device and the array of the contact pattern of the board, so that it may intersect at right angles with the direction of the pattern, and each position of the pin array and the array of the contact pattern is sought from the variation of the brightness on that line. In accordance with the result thus obtained, displacement of the position and that of the rotation over the entire surfaced part and the contact pattern are sought and the operation of the robot is controlled in accordance with that information.

Method of loading surface mounted device and an apparatus therefor

A portable teaching apparatus comprises interlock cancellation switches and at least one operating switch for producing a signal which remains effective only when the interlock cancellation switch is depressed. A box-like body with the operating switch arranged on the front surface thereof include two parallel strips of apexes on the back side thereof. Slopes which steadily approach the front side and continued from the apexes are formed between the two strips of apexes. The operating buttons of the interlock cancellation switches are mounted on the slopes respectively.
