Title: Colour display tube with improved suspension of the colour selection electrode
Inventor: MEISSNER JORG
IPC: H01J29/02
Filed: 2001-05-15
Granted: 2002-11-21
Abstract: A colour display tube (1) is disclosed, which comprises an improved suspension system of the colour selection electrode (12). The colour display tube has suspension means that are constructed so as to be self-locking. The suspension means (20) are provided with an additional flat portion (31). This plate has an aperture (32) that is shaped such that it has at least three surfaces of engagement (42,43) for the free end portion (22) of the supporting elements (17) connected to the inside of the upright edge (18) of the display window (3). When the colour display tube is exposed to shock loading, the construction of the flat portion (31) is capable of absorbing this shock without the colour selection electrode (12) becoming detached from the supporting elements (17). The action is based on the friction between the surfaces of engagement (42) and the free end portion (22). When a force is applied in the plane (47) of the resilient element (30), the suspension means (20) slip from their rest position and are locked by a surface of engagement (48), whereby the preload caused by the resilient element (30) and the spring (40) will cause the suspension means (20) to resume its original position. In this manner, a colour display tube (1) with a good positional stability of the colour selection electrode (12) is obtained. Furthermore, the colour selection electrode (12) can be reclaimed in case the colour display tube (1) is rejected because there is no need to weld the suspension means (20) to the free end portions (22) anymore.

Title: A common ball-limiting metallurgy for I/O sites
Inventor: WALKER GEORGE F
IPC: H01L23/485
Filed: 2002-02-05
Granted: 2004-05-11
Abstract: A process is described for forming a common input-output (I/O) site that is suitable for both wire-bond and solder bump flip chip connections, such as controlled-collapse chip connections (C4). The present invention is particularly suited to semiconductor chips that use copper as the interconnection material, in which the soft dielectrics used in manufacturing such chips are susceptible to damage due to bonding forces. The present invention reduces the risk of damage by providing site having a noble metal on the top surface of the pad, while providing a diffusion barrier to maintain the high conductivity of the metal interconnects. Process steps for forming an I/O site within a substrate are reduced by providing a method for selectively depositing metal layers in a feature formed in the substrate. Since the I/O sites of the present invention may be used for either wire-bond or solder bump connections, this provides increased flexibility for chip interconnection options, while also reducing process costs.

Granted: 2003-12-01
Abstract: This invention provides a method for forming a handgrip sleeve of a wrench hand tool, particularly to one for resolving the technical problems resulting from the forging (casting) tolerances when the handgrip sleeve is applied to the wrench hand tool by means of over-molding. According to this invention, an independent rigid plastic sleeve serves as a mold-closing interface between the wrench handgrip and the mold cavity, so as to resolve the problems regarding mold clamping clearance or damages resulting from forging (casting) tolerances of the wrench, so as to eliminate seeping of plastic liquid from the handgrip sleeve, and to ensure the mold is able to provide the rear section of the handgrip with a sealed configuration. As such, upon injection forming the handgrip sleeve, the handgrip sleeve may be steadily embedded and coated over the rear section of the handgrip, while ensuring the appearance of the final product and industrial applicability.
