Metal hydride nanoparticle inks provide an alternative to traditional metal inks. Metal hydride nanoinks can be printed by aerosol jet printing and cured at elevated temperatures to provide conductive patterns. As an example, printed patterns of titanium hydride nanoink on polyimide and cured by pulsed photonic curing were found to exhibit electrical conductivity, with a sheet resistance on the order of ˜150 Ω/□.

The present invention is directed to an apparatus and to a method for laser marking an object on different faces having different orientation. In a preferred embodiment the present invention is directed to an apparatus and a method for laser marking embedding cassettes on different faces thereof. The apparatus according to the invention comprises a laser source, two minors (galvo mirrors) capable to angularly deflect the laser beam, and at least one deflection mirror for each face of the polyhedron to be laser marked. The laser beam, downstream of the two minors, passes through a focus lens named “flat field lens” or “F-theta”, and optionally through a dynamic Z axis, which has the peculiarity of enlarging and shortening the light path between the target itself and the laser focal point, with the task of maintaining the focal point adherent to the plane surface to be marked, along the whole area of angular stroke of the two minors.

An example service station system may include a guide bar to provide tension on web material. An example print apparatus may include a sensor mounted to a carriage and a controller to use data from the sensor to identify that the web material is incorrectly routed with reference to the guide bar.

A mark printing device includes a driving unit driving along a driving rail of an overhead hoist transport, a printing unit being configured to print on the driving rail a mark for guiding a motion of a vehicle, a data processing unit receiving design data including design information of the driving rail and first information on a position and type of the mark from a server, an encoder unit being configured to calculate a rotation amount of a servo motor provided in the driving unit to detect a current position of the driving unit and a driving distance of the driving unit, and a control unit being configured to control the driving unit and the printing unit to print the mark on the driving rail by using the design data and second information on the current position and the driving distance of the driving unit.

A controller which causes a light emitting element to continuously perform minute emission for a plurality of dots in a level in which toner is not attached to a non-image section on an image bearing member is provided. The controller controls a first driving current for an image section and controls a second driving current used to perform the minute emission by the light emitting element in the non-image section several times in one job. In the image section, a driving current obtained by adding the first driving current to the second driving current is supplied so that the light emitting element emits light.

A system and method for performing laser marking may include identifying an event performed by a laser marking system. A laser marking unit may be driven to mark the feature on the part. The part may be illuminated with a visible illumination signal to indicate an occurrence of the event in response to identifying the event.

A printer includes at least a first printhead and a second printhead, each of which is operatively connected to a source of aqueous ink having a color that is different than the color of aqueous ink connected to the other printhead. A first source of infrared (IR) radiation is positioned between the first and second printheads and a second source of IR radiation follows the first and second printheads. The first source of IR radiation is tuned to heat color pigment particles in the aqueous ink connected to the first printhead only and the second source of IR radiation is tuned to heat color pigment particles in the aqueous ink connected to the second printhead only.
