The primary sealant assembly includes a primary actuator 5 for pressurizing the primary volume of sealant.

The sub-actuator portions are arranged along the periphery of the main actuator portion.

Each key unit comprises a main actuator portion and a plurality of sub-actuator portions.

The invention relates to a method for shaping using a machine comprising a main actuator and equipment, at least a portion of which is driven by said main actuator so as to exert forces on the material to be shaped.

An inkjet printhead includes an inkjet nozzle (100; 700; 800) with a main actuator and at least one peripheral actuator in the same firing chamber (102).

Each of the gate driving circuits (30, 30L, 30R) comprises a main driver (150, 150', 151) and an output section (200).

A sub-actuator section (20) is provided in addition to a main actuator (15) for correcting the displacement of light collecting spots caused by the displacement between the optical axis of the first beam and the optical axis of the second beam.

The ink drops jetted by activating both the main and the peripheral actuators and the ink drops generated by activating only the main actuator have the same drop weight and drop velocity.

An actuator is movable on the body member.

The work implement includes a third actuator and a fourth actuator, and is coupled to the main body.

A main drive shaft brake for a passenger conveyor includes a braking element, an actuator, and a counter-actuator.

The primary sealant assembly includes a primary actuator 5 for pressurizing the primary volume of sealant.

The sub-actuator portions are arranged along the periphery of the main actuator portion.

The actuator (12, 112, 212) can be a mechanical actuator, a pneumatic actuator, a hydraulic actuator, or an electrical actuator.

A linear actuator of the type whose function is based on a spindle (3) and a main nut (4), is provided with a safety nut (7) in connection with the main nut.
