摘要:
A piezoelectric sensor device comprising a piezoelectric element and at least one metallic body, with an insulating body arranged between each metallic body and the piezoelectric element. The insulating body substantially consists of a crystalline material or ceramics. At least one surface of the insulating body in contact with the metallic body is covered by a metallic layer in order to suppress noise signals due to a stick-slip effect and differing thermal expansion coefficients

A method is disclosed for electroforming metal screen. The method deposits photoresist over a mandrel, and then exposes the photoresist with light through a plurality of openings in a photo tool to form hardened resist pillars. Unexposed photoresist is removed without affecting the resist pillars. The method then electroforms the metal screen in areas free of the hardened resist pillars such that the metal screen forms apertures defined by each of the resist pillars, a space between at least two of the resist pillars defining a support bar that forms at a reduced thickness as compared to portions of the metal screen that are not between the resist pillars. Finally, the method detaches the metal screen from the mandrel.

The method comprises the steps of: preparing a multiple-layer film (10) comprising a first transparent protective layer (12), a second decorative layer (14) containing at least one pigment made of metal having a melting point below 250° C., and a third supporting layer (16) of thermoformable plastic material, at least a portion (13) of the surface of the first layer (12) opposite the second layer (14) being screen-printed with a polyurethane and/or acrylic based ink; thermoforming the film (10) at a temperature in the range from 130 to 180° C. and at a pressure in the range from 10 to 20 bar, in such a way as to form at least one recess (28) therein; pouring into the recess a thermosetting resin (30) which adheres to the third layer (16) of the film (10); making a covering sheet (32) adhere to the third layer (16) of the film (10) so as to enclose the poured resin (30), which undergoes a hardening process; and cutting the film (10) around the recess (28), thus producing a stratified decorative element comprising a portion of the film (10), a layer of resin (30) and a portion of the sheet (32).
摘要:
A metallization device configured to metallize a semiconductor device, including: a closed enclosure of variable volume configured to contain a metallization paste, a screen for screen printing forming a wall of the enclosure integral with the other walls of the enclosure, configured to be in contact with the semiconductor device during its metallization, and a mechanism applying uniform pressure over a mobile sealed wall of the enclosure opposite to the wall formed by the printing screen and reducing the volume of the enclosure. The volume reduction of the enclosure is configured to cause the metallization paste to uniformly pass through the printing screen.

Provisions for electrostatically charging particles, as in an electrostatic printing operation, include a corona source for providing ionization in a predetermined region, a plate electrode spaced from the corona source, a grid electrode adjacent the corona source and spaced from the plate electrode and a nozzle for directing a flow of the finely divided particles intermediate the plate and grid electrodes. The grid electrode draws ions from the corona source into the region intermediate the plate and grid electrodes. A rotatable drum may be provided proximate the region of electrostatic charging of the particles to receive the particles on the surface thereof for transportation to a printing or application zone. Alternatively, a stencil screen may be provided proximate the region of charging of the particles to direct passage of the particles therethrough to define a desired image upon a substrate proximate the stencil screen.
摘要:
A garment having an outer surface not designed for writing has at least one rewritable area comprising a layer of rewritable material deposited directly onto a selected region of the outer surface. One or more permanent artworks may be deposited onto the garment prior to deposit of the rewritable layer, which may be contiguous or non-contiguous. A stencil is provided for allowing a user to write on rewritable areas while protecting adjacent areas of the garment. In one method for forming the rewritable area, a first portion of a permanent artwork and a second portion of the permanent artwork are successively deposited on the garment, followed by curing the permanent artwork and depositing a rewritable area on the garment.
