The present disclosure relates to a seat height adjustment device for adjusting the height of a seat cushion in relation to a seat frame, in particular, an upper rail, the seat height adjustment device comprising an actuating device, which may be, in particular, an electric motor, with a toothed pinion driven by the actuating device, and a toothed gear rack, the toothed gear rack comprising a hinge end for hinging onto the vehicle seat, and a front end including a gear rod region engaging with the toothed pinion, for adjusting the hinge end upon rotation of the toothed pinion. The present disclosure provides that the toothed gear rack is hot forged, the toothed gear rack comprises, between the hinge end and the gear rod region, a reinforced region, and the reinforced region comprises a profile.

A device and method for imprinting a metal member using an external electric field and an IR band laser transmissive mold method are provided. The device includes a laser-beam generating device spaced apart from a surface of the metal member that is to be imprinted, and generating a laser beam of an IR band to radiate the laser beam onto the metal member surface, an electric-field forming device forming an electric field between both side surfaces of the metal member perpendicular to a direction in which the laser beam is incident, and a mold made of a material through which the laser beam may be transmitted, having on a surface thereof a fine pattern to form the fine pattern on the metal member surface, and performing an imprinting operation while coming into contact with the metal member surface that is softened by irradiation of the laser beam.

Described is a method of modifying material properties of a workpiece using a high-pressure-torsion apparatus, comprising a working axis, a first anvil, a second anvil, and an annular body, comprising a first recirculating convective chiller, a second recirculating convective chiller, and a heater, positioned between the first recirculating convective chiller and the second recirculating convective chiller along the working axis. The method comprises compressing the workpiece along a central axis of the workpiece and. simultaneously with compressing the workpiece along the central axis, twisting the workpiece about the central axis. The method further comprises. while compressing the workpiece along the central axis and twisting the workpiece about the central axis, translating the annular body along the working, axis of the high-pressure-torsion apparatus, collinear with the central axis of the workpiece, and heating the workpiece with the heater.

A railless billet electric induction heating apparatus and method is provided where billets are continuously or statically heated by induction by moving the billets without billet support rails through an induction coil supplied with alternating current power when the billets are in direct sliding contact with the interior surface of a clay graphite billet slider disposed within the induction coil. The clay graphite billet slider can also provide thermal insulation between the induction coil and the clay graphite billet slider to eliminate the requirement for a separate induction coil refractory.
