Abstract: A prediction control development device according to one aspect of the present invention generates a prediction model of a control amount by analyzing first time-series data of the control amount and provides the generated prediction model to a controller. The prediction control development device acquires second time-series data showing transition of a value of the control amount during prediction control using the prediction model, and evaluates prediction accuracy of the prediction model based on a difference between a prediction value by the prediction model and a value of the second time-series data. When the prediction accuracy of the prediction model is not allowable, the prediction control development device analyzes the second time-series data to newly generate a prediction model of the control amount, and provides the newly generated prediction model to the controller.

This results in reduced working time. In addition, since only the adapter plate is replaced, cost savings can be achieved by reusing the slide cam. Furthermore, a given slide cam can be used while still maintaining flexibility in design and use of the slide cam die.

Abstract: A press has a bush (56) set in a cylinder (54) which may then be rotated to position a stud (14) over a sheet of metal into which it is to be inserted. The cylinder is then lowered to insert and fix the stud in place. In a stud delivery system, studs (14) are fed through a delivery tube (12) shank first into a breech (20) in which a pair of pivoted members (24, 26) form a half barrel.

A thrust member (38) can push a stud (14) along the breech (20) so that the stud tip passes into the tapered aperture (34), the stud shaft then being horizontal. As the stud is pushed further along the breech, passage of the stud bead (18) through the tapered aperture (34) forces the pivoted members (24, 26) apart. After passage of the head (18), the pivot members (24, 26) return to their former position.

Abstract: A crimp press having an eccentric guide in which an eccentric tang having a bearing runs. In contrast to the known eccentric guides, the eccentric guide is not straight but instead has a curved region on one side. As a result, during the first 90.degree. of the eccentric shaft rotation, the tappet covers the greatest part of the stroke path, and in the second 90.degree. of rotation of the eccentric shaft, only a short stroke path is executed, during which the deformation of the contact takes place. A crimp press with the eccentric guide has a more lightweight structure, is equipped with a smaller reduction gear and requires a lower rotational speed of the drive motor, as compared to conventional crimp presses.

Abstract: A simple household type can crusher to be used on aluminum beverage cans causes a crushing action in which the ends of the can are rotated so that they lie flat on an upper surface of the crushed can with the peripheral wall of the can remaining in tact on one side of the crushed can for inspection of the printed material so that the origin of the can can be determined. The can crusher includes a pair of handles which, when rotated to the vertical position brings two rods into contact with the upper surface of the can while it lies horizontal thereby creasing the can and causing the ends of the can to rotate towards the creased portion. When the handles are rotated to the horizontal position this brings two paddles into contact with the partially rotated ends of the can and, with minimal pressure on the handles, the can is compressed into a readily salvagable shape of four inches by six inches. The handles are then rotated to the original clear position which allows easy removal of the compacted can.
