Abstract: A ground clamp (10) is provided for use with a ball stud (12) having a shaft (14) that terminates in a spherical end (16), and includes a body (20), a first jaw (22), and a second jaw (24). The first jaw (22) includes two fingers (40) that define a slot (44) through which the shaft (14) can extend when the ball stud is inserted into the clamp. The second jaw includes a laterally extending platform (50) and a rib (52) extending from the platform to be located within the slot with the jaws in a closed position. The second jaw has a concave clamp surface (54) defined in the platform (50) and the rib (52) that is engageable with the spherical end as the second jaw moves to the closed position to guide the jaws and the spherical end into proper alignment.
Abstract: A lamp connection structure, configured to connect a lamp of a backlight module, is provided. The backlight module has a circuit board formed with a through-hole, which is defined by a side wall. The lamp connection structure comprises a clamping portion and an embedding portion. The clamping portion has a first end and a second end, and the first end is adapted to fix and to electrically connect to the lamp. The embedding portion has a first end and a second end. The first end is connected to the second end of the clamping portion while the second end of the embedding portion is inserted through the through-hole and contacting with the side wall.
Abstract: A coupling element (2) is proposed for the combining of at least two elongate lamps with in each case two ends. For this purpose, the coupling element (2) has a continuous receptacle area which is provided for receiving an end of each lamp. The receptacle area comprises a reflector (6) in order to reduce the luminance decrease in the region between the lamp ends. With one or a plurality of coupling elements according to the invention in conjunction with two or more elongate lamps, illumination systems having different luminous lengths can be realized in a modular manner.

Abstract: The present invention is a cost effective, reworkable, LGA-based interconnection for use between two circuit members such as a ceramic module and an FR4-based system board. The resilient contact members allow the reliable interconnection of two circuit members, even though the circuit members may have significantly different CTEs and have interconnections where the distance from neutral point is great enough to crack BGA or CGA solder connections. For factory reworkable applications, the ends of the contact members are semi-permanently attached to both the module and the system board. For certain field separable applications, semi-permanently attaching only one of the ends of an LGA to either the module or the system board provides increased reliability.

Abstract: An etching agent and an electronic device manufacturing method using the etching agent. The etching agent contains, in a solution, hydrofluoric acid at a concentration of 0.05 to 0.5 mol/l, and halooxoacid ions, represented by the formula (XO.sub.n).sup.p- (wherein X is a halogen element, n is 3, 4 or 6, p is 1, 2 or 3), at a concentration of at least 0.01 mol/l. An electronic device manufactured using the etching agent requires only a single etching step to etch both conductive layers (such as aluminum) as well as ohmic contact layers (a-Si).
Abstract: A connector for discharge electrodes of luminous gas tubes includes an insulative barrel receiving a power cable at one end for attachment to a fixed end of a resilient contact member. The opposite end of the barrel is open and threaded, to receive the crimped and headed tip of a gas tube having electrode conductors projecting therefrom. A lock element is applied to the crimped portion of the gas tube end and is axially captured thereon so that following insertion of the tube tip and lock element into the barrel open end, a cap surrounding the gas tube engages the threads of the barrel to radially and axially retain the tube tip within the barrel interior with its electrode conductors firmly biased against a displaceable end of the resilient contact member.

Abstract: A connector mechanism for linking the ends of successive fluorescent fixtures includes a pair of plates defining the ends of the fixtures, one said plate including a projecting hook portion which extends through the other said plate. The hook poriton includes a cam surface inclined toward the first plate, the second plate including a slide having a locking shoulder positioned to engage the cam surface. A threaded connection to the slide enables the slide to be drawn along the cam surface and accordingly to clamp the end plates tightly against each other.
Abstract: A method of producing a layered structure, the method including forming a spacer layer on a substrate, forming a parting layer on the spacer layer, forming a first masking pattern on the parting layer the first masking pattern delineating field regions in a first metal layer, etching the spacer layer and the parting layer in accordance with the first masking pattern, depositing a first metal layer, depositing an etch barrier layer, dissolving the parting layer to remove the masking pattern and the first metal layer and etch barrier layer in the field regions, depositing a passivation layer on the spacer layer, depositing a dielectric layer on the passivation layer, forming a second masking pattern on the dielectric layer, exposing the etch barrier layer in accordance with the second masking pattern, depositing a second metal layer, forming a third masking pattern on the second metal layer and etching the second metal layer in accordance with the third masking pattern.
Abstract: A modular, linear-type lighting fixture may include an elongate housing having lengthwise ends, and a pair of endplates adapted for sealing attachment to either lengthwise end of the housing, each of the endplates having respective perimeter surfaces adapted for attachment to any one of a bridge adapted for angularly-directable extension of the housing, a bridge adapted for linear extension of the housing, and an endcap. A modular lighting fixture may include first and second elongate housings each having ends, pairs of endplates for being respectively mated with the first and second ends of the first and second elongate housings, the endplates each having a rim, and a bridge adapted for joining one of the endplates of the first elongate housing with one of the endplates of the second elongate housing by sealing cooperation with the respective rims thereof. A lighting fixture may have one or more isolated raceways therein.
