Abstract: An electronic sequencing system comprised of two groups of three identically operating sequencers and circuitry that combines the outputs of these sequencers so that accurate, flexible and reliable sequencing of devices is obtained. Each sequencer is comprised of a microprocessor, memory, and peripheral circuits. The individual sequencer outputs are combined such that at least one of the corresponding system outputs will activate the device to be sequenced if at least two of three corresponding individual sequencer outputs signal that the device should be activated. Additional reliability is obtained by combining the outputs of each group of the identically operating sequencers to control the devices to be sequenced. Reset circuitry is also provided to simultaneously reset the sequencers and to prevent premature outputs from activating the devices to be sequenced.

Abstract: A control method and unit for controlling an industrial robot or a manipulator in which a parameter a of a transfer function of a reference model is determined in accordance with the positioning time and a moving angle of the manipulator from the starting point to the end point of control and each of control gains are determined in accordance with the parameter thus determined so as to average or make the positioning time uniform among arm shafts of the manipulator. With this construction, the dispersion of the positioning time among the arm shafts are removed and a high speed positioning control of the manipulator is realized.

Abstract: A film folding control apparatus of a wrapping machine is a type in which a length of film fed by a film feeding mechanism is extended at a predetermined section of the wrapping machine. An article to be wrapped is raised into taut engagement with the extended film from therebelow. The edges of the film are folded under the bottom of the article, thereby wrapping the article in the film, by a film folding mechanism comprising left, right and front folding plates. The control apparatus comprises a data setting device for setting film length data, film tension data and tray type data in dependence upon a number of an article to be wrapped. A preset memory stores this data in correspondence with the number of the article to be wrapped. A control unit is responsive to an input of the number of the article to be wrapped.

Abstract: A control system for cooking apparatus including a heat source, a heat control system and a back-up thermostat system having a back-up temperature probe. The control system includes a digitally controlled microcomputer which provides control transfer from a cooking computer temperature probe upon probe failure or shorting of a control transfer relay or a microprocessor software failure to a back-up temperature controller.

Abstract: A system for carrying out a cooperative control operation for a plurality of automated devices connected together in which the individual operations of the automated device can be controlled individually in accordance with a program. In the control method in this system, the controlling of various automated devices is practiced by inputting a program described in a language which has a unified system, and translating this program in accordance with the combination of the automated devices.
