摘要： An electrolytic membrane valve and method of its manufacture are provided. The valve includes a substrate comprising an opening and a conductive membrane impermeable to a conductive media and sealing the opening, as well as a cathode on the substrate and in communication with the membrane through the conductive media, and an anode on the substrate directly contacting the membrane. The anode is at least partially protected from electrochemical corrosion, and upon application of an electrical potential between the anode and the cathode, the membrane ruptures to allow flow of the conductive media through the opening.

摘要： There is described a printing press (100) comprising a printing group (2) adapted to apply on a substrate at least one ink or varnish vehicle containing magnetic or magnetisable flakes and at least one magnetic orientation unit (10) located downstream of the printing group (2) along a path of the substrate, which magnetic orientation unit (10) includes at least one magnetic-field-inducing device (12) adapted to orient the magnetic or magnetisable flakes contained in the ink or varnish vehicle applied on the substrate to induce an optically-variable effect in the ink or varnish vehicle. The printing press (100) further comprises a drying/curing unit (15) located along the path of the substrate and cooperating with the magnetic orientation unit (10), which drying/curing unit (15) is adapted to dry or cure the ink or varnish vehicle applied on the substrate following orientation of the magnetic or magnetisable flakes. The drying/curing unit (15) is mounted on a movable supporting structure (16) that is adapted to move the drying/curing unit (15) between a working position (WP), where the drying/curing unit (15) is cooperating with the magnetic orientation unit (10) and which is located proximate to the path of the substrate next to the magnetic orientation unit (10), and a retracted position (RP), where the drying/curing unit (15) is retracted away from the magnetic orientation unit (10) and from the path of the substrate.

摘要： A screen printing method includes performing a destaticizing action that removes static electricity with which a screen mask is charged, through a mask support member, which is positioned on a lateral side of a circuit board, before bringing the circuit board into contact with a lower surface of the screen mask, by bringing the conductive mask support member into contact with a lower surface of the screen mask as a result of raising the mask support member. The method includes subsequently performing screen printing by bringing the circuit board into contact with the lower surface of the screen mask as a result of raising the circuit board.

摘要： A screen printer in which a photoelectric sensor and squeegees are fixed to a slider, when outward movement printing in which solder on a screen is rolled by an outward movement of the right squeegee is completed, the right squeegee is separated from a state of contacting a right end of a solder roll and a squeegee position pl at that time is input, and, subsequently, the slider is returned until the photoelectric sensor detects a left end of the solder roll and a squeegee position p2 at this time is input. An amount (a solder roll width) of solder remaining on the screen is calculated by subtracting a movement amount from the squeegee position p1 to the squeegee position p2 from a distance from the right squeegee to an optical axis position of the photoelectric sensor on the screen.

摘要： A screen printing apparatus includes a substrate positioning part that upwardly and downwardly moves a substrate with the substrate clamped by a clamp member to thereby bring the substrate into contact with a mask stretched in a frame body and fixed in a predetermined height position from an underside of the mask and position the substrate in a predetermined height position, a mask suction part that is provided in the clamp member and sucks the mask in contact with the substrate, and a screen printing part that prints paste on the substrate through a pattern hole formed in the mask by sliding a squeegee on the mask to which the paste is supplied. The mask is pressed up by a predetermined amount through the substrate with the mask sucked by the mask suction part when the substrate is upwardly moved by the substrate positioning part.

摘要： A method of making a bas relief from a two-dimensional image includes converting a two-dimensional image to a gray-scale image that comprises a plurality of shades of gray. Each shade of gray corresponds to a respective elevation of a three dimensional representation of the two-dimensional image. The gray-scale image is then converted to a half-tone bitmap image that is etched onto a print screen stencil. Meltable powder is forced through the open mesh areas of the print screen stencil to form a three-dimensional pattern of powder on a substrate positioned beneath the print screen stencil in spaced-apart relationship therewith. The three-dimensional pattern of the powder corresponds to the three-dimensional representation of the two-dimensional image. The three-dimensional pattern of powder is then heated to fuse the powder together to form a bas relief.
