In an example embodiment, a universal compacting mechanism can be selectively engaged with an existing trash receptacle of any size or shape. The universal compacting mechanism comprises a housing assembly, a motor, a power source, a plate assembly, and an attachment mechanism. The housing assembly includes a threaded rod extending along at least part of the longitudinal axis of the housing assembly. The motor engages with the threaded rod for rotating the threaded rod about the longitudinal axis of the threaded rod. The power source is electrically connected to the motor for providing power to the motor. The plate assembly includes a compaction plate. The plate assembly is engaged with the threaded rod such that rotation of the threaded rod causes a raising or lowering of the plate assembly. The attachment mechanism selectively engages the trash compactor to an existing trash receptacle of any size or shape.

A number of pulses output from an encoder is counted, a number of pulses output from a command pulse output unit is counted, and a difference between the number of pulses that has been counted by the command pulse counting unit and the number of pulses from the encoder is calculated. Then, a condition is changed such that speed/acceleration of a pulse motor increases when a difference value between a deviation threshold and the difference is smaller than a predetermined range, and the speed/acceleration of the pulse motor decreases when the difference value is greater than the predetermined range, and whereby the pulse motor is controlled based on a position of a slider detected by a slider position detection unit, a position of the slider that has been set, and the pulse condition that has been changed.

A press brake includes a ram to which an upper or lower tool can be attached; a movable ram driver; and a controller that controls the ram driver, wherein the ram driver includes a rotation/linear motion converter composed of a screw fixed to the ram and moves upward and downward as the ram moves upward and downward, and a nut screw-coupled with the screw; a drive rotation body arranged rotatably about a rotation axis of the nut; a first motor arranged in a fixed state; a first power transmitter that transmits rotation of the first motor to the nut at high speed and with low torque; a second motor arranged in a fixed state; a second power transmitter that transmits rotation of the second motor to the drive rotation body at low speed and with high torque; and a clutch provided between the nut and the drive rotation body.

A method and apparatus for making pouches is disclosed. It includes using one or more of the following features: using two servo motors to drive a platen, providing a calibration routine is run at start-up and/or after the machine has been operating; controlling in response to feed back from the servo motor(s) such as feedback indicative of the distance the platen travels; the feedback is not of force exerted by the platen; and/or the platen is controlled to prevent unacceptable fracturing of the film laminate.

A press machine includes a drive mechanism that moves at least one of an upper tool and a lower tool and machines a workpiece placed between the upper and lower tools. The drive mechanism includes a first drive source that rotates a screw shaft serving as an advance-retract component and a second drive source that rotates a nut connected to the screw shaft. A structure including the upper tool and lower tools includes a casing supporting the screw shaft such that the screw shaft is rotatable, a movable member that is movably formed in the casing and can contact an end of the screw shaft or retract therefrom, and a drive unit that moves the movable member.
