摘要： A vehicle suspension axle wrap is a composite tubular structure of cast or forged shells of part-tubular shape. The shells are assembled into a tubular form and welded together at juxtaposed edges. The shells can be cast or forged accurately to shape and profile to provide an improved quality axle wrap. Wall thickness variations can be designed into the shells. The juxtaposed edges are shaped to space the welding at the edges from the interior of the assembled axle wrap. The edges are beveled adjacent the external circumferential surfaces of the shells to provide a V-shaped groove at which the welding is made. There is a stepped engagement at the edges between the V-shaped groove and the internal surface of the axle wrap to prevent the welding from extending to the internal surface. Each shell is formed with an aperture at which a welded joint can be made between the axle wrap and an axle.

摘要： A CMP station can be closed loop controlled by using data obtained by an inline metrology station from a first polished wafer to affect the processing of subsequent polished wafers. The first wafer is polished and measured by the inline metrology station. The metrology station measures at various points the array dielectric thickness, field dielectric thickness, barrier residue thickness and metal residue thickness. The data is then inputted into an algorithm and polishing parameter outputs are calculated. The outputs are sent to the CMP station and used to supplement or replace the previous polishing parameters. Subsequent wafers are polished on the CMP station using the revised polishing parameters.

摘要： A hollow vehicle suspension beam (1) has opposed side walls formed with recesses (11) in which an axle wrap (2) is located and secured by welded jointing (12, 13) internally and externally of the opposed side walls to provide a strong joint between the beam and axle wrap. The beam may comprise at least one component (5, 6) of a generally U-shaped section the opposed limbs of which provide at least part of the opposed side walls of the beam, and the mouth of the section provides an access opening into the interior of the beam for the internal welded jointing (12) to be made at the axle wrap. One embodiment has the beam comprised of two of the U-shaped components (5, 6) disposed with their mouths opening in opposite directions to provide access to the interior of the beam for the internal welded jointing to be made at the axle wrap (2) before the mouths are closed by closure components (15, 16). Another embodiment has the opposed side walls formed in combination by the opposed limbs of a U-shaped component and the space between the plate components being closed off by closure components after the internal welded joint have been made.

摘要： An MOV element is physically and electrically connected to a heat sensitive material which changes from a low impedance path to a high impedance path, such as a spark gap, when the temperature of the MOV element rises to a temperature below that at which the MOV will enter into its thermal runaway state. More specifically, the heat sensitive material is located on a surface of the MOV and is electrically connected in series with the MOV. In operation, as the MOV gets hot, it heats the heat sensitive material. As the heat sensitive material gets hot, it starts to separate from the surface of the MOV to form a spark gap which is electrically connected in series with the MOV element to help dissipate excessive voltage. The heat sensitive material on the surface of the MOV element can be a coating of epoxy which cracks and/or breaks away, at least partially from the surface of the MOV element during the occurrence of a high voltage transient surge, or it can be a solder that sputters to form an arc path during the occurrence of a high voltage transient surge. In operation, when a GFCI is subjected to a high voltage transient surge above a certain magnitude, the heat sensitive material forms a spark gap which is in series with the MOV and prevents the GFCI from going into its destructive thermal runaway condition. Thus, prior to the MOV entering its thermal runaway state, it goes from being only an MOV to an MOV in series with a spark gap which can be used to protect an up stream GFCI during the occurrence of a high voltage transient surge.
摘要翻译：当MOV元件的温度上升到低于MOV的温度时，MOV元件物理和电连接到热敏材料，该热敏材料从低阻抗路径变化到高阻抗路径，例如火花隙，进入其热失控状态。更具体地说，热敏材料位于MOV的表面上并与MOV串联电连接。在操作中，当MOV变热时，它会加热感热材料。当感热材料变热时，它开始与MOV的表面分离，以形成与MOV元件串联电连接的火花隙，以帮助消散过大的电压。 MOV元件表面上的热敏材料可以是在高电压瞬变浪涌发生期间至少部分地从MOV元件的表面开裂和/或断开的环氧树脂涂层，或者它可以是在发生高电压瞬变浪涌期间，焊料溅射形成电弧路径。在操作中，当GFCI受到高于一定量级的高电压瞬态浪涌时，热敏材料形成与MOV串联的火花隙，并防止GFCI进入其破坏性热失控状态。因此，在MOV进入其热失控状态之前，它只能从MOV到MOV与串联的火花隙串联起来，该火花隙可以在发生高压瞬态浪涌时用于保护上行GFCI。

摘要： Provided is a method of fabricating gate dielectric layers having variable thicknesses and compositions over different regions of a semiconductor wafer. In a preferred embodiment of the present invention, a gate oxide layer is first grown over the various regions. Regions that are to have a relatively thicker, unhardened gate dielectric are masked and the wafer is exposed to a remote low energy nitrogen plasma. After the nitridization process is completed, the mask is removed and the wafer is exposed to further oxidation. The regions where oxynitrides have been formed act as a barrier to the oxidation process. Consequently, different oxide thicknesses can be grown on the same wafer, thinner and hardened where nitridization has been performed, and thicker and not hardened in those regions that were masked during the nitridization. Variable thickness gate dielectrics in accordance with the present invention may be particularly advantageous in semiconductor integrated circuits involving both digital and analog devices.

摘要： A modular integrated circuit tester includes a set of tester modules for carrying out a sequence of tests on an integrated circuit device under test (DUT). Each module includes a memory for storing instruction sets indicating how the module is to be configured for each test of the sequence. Before the start of each test, a microcontroller in each module executes an instruction set to appropriately configure the module for the test. The microcontroller in each module thereafter sends a ready signal to a start logic circuit in each other module indicating that it is ready to perform the test. When the microcontrollers of all modules taking part in the test have signaled they are ready, the start logic circuit in each module signals its microcontroller to begin the test. The modules then carry out the test with their activities synchronized to a master clock signal. The process of configuring the modules, generating the ready signals and commencing a test is repeated for each test of the sequence.

摘要： A ground fault protection circuit for plural loads connected across a power source with plural branches which can be used where the loads are unbalanced. Each branch includes a ground fault circuit interrupter device that has a common line for the electronics of the GFCI separate from the neutral line from the power source to the load where the common lines for the electronics for the ground circuit interrupter devices in each branch are connected to a common point. The ground fault protection circuit employs plural ground fault circuit interrupter devices and eliminates nuisance tripping. The common line for the electronics for a GFCI is routed through the core of the current sensing transformer of the GFCI. The separate neutral line for the electronics, connecting the common lines for the electronics for plural GFCI devices and routing the common lines for the GFCI electronics through the core of the transformer of each GFCI, eliminate improper GFCI operation due to unbalanced loading. The ground fault protection circuit may be used for a three phase power source.
