The present disclosure provides a thermal print head for achieving fine printing. A thermal print head of the disclosure includes: a substrate, having a substrate main surface and a substrate back surface facing opposite sides in a z direction; a resistor layer, disposed on a side of the substrate main surface and including a plurality of heat generating portions arranged in a main scan direction to generate heat by energization; a wiring layer, disposed on the side of the substrate main surface and including a conduction path for electrically conducting the plurality of heat generating portions; a metal layer, interposed between the substrate and the wiring layer with the resistor layer; and an insulating layer, interposed between the metal layer and the wiring layer with the resistor layer. The conduction path includes the metal layer. The metal layer includes tantalum (Ta).

A system and method for selective heating and/or sintering of a material including first and second substrates, an array of one or more resistive heating elements arranged on a planar surface of a substrate and material to be heated located on the other substrate.

Provided herein is a printing apparatus including a printhead movable between a first position and a second position. The printhead includes a first substrate and a second substrate. The first substrate and the second substrate define at least a first burn line and a second burn line, respectively, of heating elements disposed adjacent to a first edge and a second edge, respectively of the printhead. A printhead bracket receives the printhead in one of the first position or the second position. In the first position, the heating elements of the first burn line perform a printing operation and the printhead bracket is configured to preclude operation of the heating elements of the second burn line. In the second position, the heating elements of the second burn line perform a printing operation, and the printhead bracket is configured to preclude operation of the heating elements of the first burn line.

In some examples, a thermal imaging head includes a resistor and conductors connected to end portions of the resistor to pass an electrical current through the resistor. The resistor includes gaps at the end portions of the resistor, each gap of the gaps reducing a cross-sectional area of a respective end portion of the end portions of the resistor relative to a cross-sectional area of a central portion of the resistor.

Disclosed is an assembly line for processing products. The line includes, on one hand, a plurality of consecutive stations for processing the products and, on the other hand, a moving unit for moving the products between the stations within the line, in particular from an upstream station in which the products have just been processed, to a downstream station in which the products must later be processed. The moving unit essentially includes at least one self-contained, self-supported, movable carriage moving on the ground and having the products resting thereon during the movement thereof within the line. Also disclosed is a corresponding implementation method and to a corresponding use of the carriages.

A thermal contact device may include a thermal contact die embedded in a moldable material. The thermal contact die may include a number of resistors integrated into the thermal contact die, and a number of heater drivers integrated into the thermal contact die and electronically coupled to the resistors. The moldable material is coplanar with a thermal contact side of the thermal contact device. Further, the moldable material includes at least one gradient edge along a medium feed path.

A thermal printer, includes a head unit including a thermal head configured to perform printing on a recording sheet; a platen unit, which includes a platen roller configured to convey the recording sheet, and is separably combined with the head unit; a printer main body, which has a recording-sheet receiving portion configured to receive the recording sheet, and has the head unit mounted thereto; a printer cover, which has the platen unit mounted thereto, and is coupled to the printer main body so as to be pivotable; and a separator, which is provided in the recording-sheet receiving portion, and is configured to separate parts of the recording sheet, which is rolled into a roll shape around a core body, folded on each other at a rolling start portion, which is rolled around the core body and has a turn-back shape.
