A device for marking a work piece that is at least partially formed or reshaped through a thermal process is provided. The device includes a plurality of heating elements distributed laterally on a surface that is placed against the work piece and can be individually controlled for local heating of a work piece surface. Each of the heating elements includes a solid material with a surface structure and a heating structure. The surface structure includes at least one of a specifically or randomly varied topography. The surface structure can be at least partially heated through the heating structure.

A method of imprinting a substrate (180), comprising affixing a flexible stamp (104) carrying an imprinting pattern (106) to a first carrier (102) comprising an array of apertures (112) which, by gas pressure, either pull the flexible stamp towards the first carrier or push it away; pushing it to a second carrier (170) carrying a substrate (180) with a resist layer (182), leaving a gap (190) for creating a controllable contact area between the flexible stamp and the substrate and space (196) between the first carrier and the flexible stamp; progressively pushing areas of the flexible stamp into the resist layer to imprint it; developing the resist layer; and progressively releasing the flexible stamp by applying suction through successive apertures whilst controlling the inward flow of gas to the space (196) through the apertures that are not yet under suction in order to maintain the space (196) there above ambient but below a predetermined maximum pressure.

The machine (1) includes at least one assistance subassembly (10) having: an endless chain or belt (16); a plurality of thrust members (20) connected to the chain or belt (16) in succession and projecting from the chain or belt (16), and a drive device (21) of this chain or belt (16), several thrust members (20) are brought into the path (3) of the sliders (8) connected to the grippers (4) for gripping the film (F), so that at least one of the thrust members (20) comes to bear against at least one of these sliders (8) and exerts a thrust on this slider to assist the displacement of this slider along the rail (5e) on which this slider moves.

A system may include an energy source configured to be directed at a first location in a fluid and configured to generate a wave in the fluid. A system may include a laser system configured to generate a laser pulse directed at a second location in the fluid and configured to illuminate at least a portion of the wave in the fluid. A system may include a sensor configured to detect the illuminated wave and generate an electric signal based at least in part on the illuminated wave. A system may include a processing system configured to: receive the electric signal from the sensor; and calculate a relative viscosity of the fluid based at least in part on the electric signal received from the sensor.

A method is described in which a part is placed within a chamber. Vaporized solvent is provided within the chamber such that the solvent condenses onto and treats the part. A vacuum is then applied to the chamber to extract the solvent and stop the treatment. The vacuum is controlled such that a pressure within the chamber over time has a predefined profile to prevent defects in the part from occurring due to the extraction of solvent from the part.

An injection molding system includes an extruding system, a discharging channel, a molding device including a first and second mold cavities, and a pressure regulating system regulates pressures inside the first and second mold cavities. An injection molding method includes providing a molding device having a first and second mold cavities, a first feeding port in communication with the first mold cavity, and a second feeding port in communication with the second mold cavity; sensing a first pressure in the first mold cavity, and injecting a first gas into the first mold cavity until the first mold cavity is sensed to have a first predetermined pressure; and sensing a second pressure in the second mold cavity, and injecting a second gas into the second mold cavity until the second mold cavity is sensed to have a second predetermined pressure, wherein the first and second predetermined pressures are different.
