Abstract: A method for cutting integrated circuit packages includes providing an integrated circuit package, and cutting the integrated circuit package with a water jet.

Abstract: A wafer cutting apparatus which includes a wafer saw, a detector, and a control unit. The detector detects a variable of a wafer being sawed. The control unit utilizes the variable to control the saw.

Abstract: A method of operating a machine for cutting stacks of material in sheets. The machine's basic settings are established in accordance with parametric settings (machine parameters). Specific parameters (program parameters) are permanently assigned to an overall material-cutting program. Individual parameters (routine parameters) are permanently assigned to paper-cutting routines within the overall program. The machine parameters are stored and remain valid until modified or replaced by specifically requested routine parameters. The routine parameters are stored and remain valid until modified. The method allows the operation of the machine to be adapted to the various conditions that occur during the job.

Abstract: The novelty perforating machine perforates paper, such as paper money and similar paper or paperlike sheet material, in a manner that the original purpose of the paper is not lost, but when it is held to the light, a light pattern representing the novelty is seen. Thus, a paper money bill can be perforated with a selected pattern to form a novelty item, such as an outline picture of the area in which the perforating machine is situatuated.

Abstract: The machine controlled by the device comprises a set of cutting tools interchangeable in dependence on the blank to be cut, means adjustable in dependence on the jobs to be performed by each tool, and means for actuating the adjustable means. The control device comprises a memory (1) associated with each cutting tool in order to store the data relating to the characteristics of the tool and of the operations for adjusting the machine (5) in order to use the tool, reading means (2) for reading the data in the said memory, means (3) for displaying a menu relating to the data and control means (4) for generating and transmitting control signals (6, 7, 8) to the actuating means in dependence on the menu.

Abstract: Method and positioner apparatus are provided for minimizing the time required to move a tool along a continuous path such as over material conveyed continuously thereunder. The continuous path is discretized into geometric moves, pairs of which are preferably joined to minimize positioner stop and go. Ranges of velocities are analyzed for each discrete move and are adjusted to overlap for fitting a continuous velocity curve therethrough. Optimizing of the velocity ranges for maximum tool acceleration and velocity results in a time-optimized velocity profile for the tool. Velocity profiles for each discrete move are further optimized to maximize acceleration and deceleration resulting in the most time spent at maximum velocity. Throughout, the method is cognizant of the effects of time and displacement being measured in integer increments. Rounding is appropriately performed and move parameters are adjusted appropriately.

Abstract: An automatic carton slitting machines includes a transmission means for moving cartons, a sensing and positioning means for detecting and positioning the cartons at locations desired, a slitting means for slitting the carton and a control unit for coordinate and control the operations of all other means. The cutter means includes two spaced cutter sets each has a motor driven rotating saw cutter with adjustable slitting angle. One of the cutter sets is movable by a cutter set moving means for changing spacing distance between the cutter sets to process carton of different width. The cutter means also has a frame lifting means to adjust cutter sets height for processing cartons of different height. Through coordinating the transmission means, cutter set moving means and frame lifting means may coordinate their motion so that the cutter sets may move in three dimensions against the carton for automatically cleaving cartons of different size.

Abstract: An application for periodically applying a controllable force to a movable part has a force applying member, particularly for cutting a web, and a driver for driving the force applying member. The driver is controlled by a force-indicating signal produced by a lock-in amplifier to which a force-responsive signal and a reference signal are inputted. The lock-in amplifier operates to eliminate or reduce any noise present in the force-responsive signal.

Abstract: A machine for cutting a sheet material incorporates a system for clamping the sheet material against an underlying support surface, which system employs linear arrays of clamp units, each unit including a separate clamping member having a head portion with a flat top surface and a peripheral element constructed to engage an edge portion of the sheet material. The clamping members are disposed in spaced relationship along marginal portions of the support surface, an actuator is proveded for effecting movement of the clamping members between release and clamp positions. Because of the construction of the clamping members, the top surfaces thereof will be substantially flush with the surface of the clamped material being cut, thus enabling a cutting head having an associated glide plate to pass thereover, in contact therewith, without substantial interference or impediment.
