20160118308 | Method And Apparatus For Semiconductor Testing At Low Temperature - A method for testing a plurality of semiconductor devices arranged on a strip may include forming an array of semiconductor devices on a frame, wherein contact pads of adjacent semiconductor devices are shorted, partially cutting the strip to electrically isolate individual semiconductor devices in the array, placing the strip on an adhesive tape configured to withstand low temperatures (e.g., below −20° C. or below −50° C.), arranging the strip and tape on a test chuck, exposing the test chuck, strip, and tape to temperatures below an ambient temperature and testing the plurality of semiconductor devices while exposed to a low temperature. In one embodiment a KAPTON™ film is used as the adhesive tape. | 04-28-2016 |

20150129733 | APPARATUS FOR MOUNTING A FLAT SCREEN ON A SURFACE - The invention regards an apparatus for mounting a flat screen on a surface wherein the flat screen comprises at least two fixtures. The apparatus comprises, two mounting members adapted to be attached to the fixtures on the flat screen and a wire with one end connected to one of the mounting members and the other end connected to the other mounting member. The mounting members comprise an axle adapted for the wire to be coiled around for changing the length of free wire between the mounting members and retaining means at a radially greater distance from the wire coiled around the axle, adapted to retain the wire hereby preventing uncoiling of the wire. | 05-14-2015 |

20080204176 | Unequally tapped coil solenoid valve - This invention discloses a magnetically latching solenoid valve and a solenoid thereof. The solenoid includes a coil disposed around a bobbin and divided into two sections by a tap for adjustable pull and release forces to a plunger disposed therein. A first section of the coil, through magnetic induction, pulls the plunger toward a fixed stopper disposed at the lower end of the bobbin and coupled to a cylindrical yoke. A permanent magnet is disposed between the stopper and the yoke. On contact with the stopper, the plunger is held in place by the permanent magnet even after the current flow is removed from the first section of the coil. A second section of the coil, with a differing magnetic induction, returns the plunger. By the operating current at the common tapped junction of the coil, the electromagnetic force generated by the first section will add to the fixed force from the permanent magnet while the electromagnetic force generated by the second section will subtract from the fixed force from the permanent magnet. By using a tapped coil, a simpler and more efficient electronic drive can be used with reduced electrical switching losses. | 08-28-2008 |
