Appl. No.:

10/062152

Inventors:

Richard Ramos - La Habra CA
Richard E. Phelan - Huntington Beach CA

Assignee:

SierraTherm Production Furnaces, Inc. - Watsonville CA

International Classification:

H05B 308

US Classification:

219541, 219343

Abstract:

An electrical heating element, such as a graphite block, is resiliently held in electrical contact with a support block by a plurality of spring loaded connectors. The support block is electrically connected to an electrode. The spring loaded connectors extend through a plate, the heating element, and the support block. The connectors extend through slot shaped openings in the heating element such that the heating element can move in the direction of its length relative to the plate and the support block to provide a first degree of freedom between the electrode and the heating element. There may be up to six degrees of freedom in the mechanical connection between the electrode and the heating element.

Inventors:

Richard Ramos - La Habra CA, US

Assignee:

SierraTherm Production Furnaces, Inc. - Watsonville CA

International Classification:

B23K037/04

US Classification:

228 495, 228 471, 414217

Abstract:

A low shock work transport system for moving workpieces into a pressure vessel without significant vibrations or mechanical shocks. The pressure vessel has two opposing ends with a sealable port in each of the opposing ends. A vessel rail is contained entirely within the pressure vessel with the two ends of the rail adjacent the ends of the pressure vessel. A movable rail is adjacent each end of the pressure vessel. Each movable rail is movable between a first position in which one end of the movable rail is within the pressure vessel and contiguous with the adjacent end of the vessel rail, and a second position in which the one end of the movable rail is outside the pressure vessel such that the sealable ports can be sealed. The workpieces are moved by sliding them over the upper surfaces of the rails.

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

H02M 3335

US Classification:

363 21

Abstract:

An isolated controller circuit responsive to an input signal voltage from the output of a low-pass filter referenced to an isolated reference potential; the controller circuit being characterized to provide a control signal at a signal output terminal referenced to a non-isolated reference potential. The isolated controller circuit comprises: a reference signal source referenced to the isolated reference potential for providing a reference signal and an amplifier and compensation means for amplifying and compensating the signal difference between the input signal and the reference signal to provide a compensated control signal referenced to the isolated reference potential. The controller circuit also has an oscillator and coupling means for coupling and scaling the compensated control signal referenced to the isolated reference potential and it provides the control signal at the signal output terminal referened to the non-isolated reference potential.

Abstract:

A method and apparatus for placing and attaching solder balls to a substrate having conductive pads in a predetermined pattern is disclosed. The substrate is placed on a carrier plate. An alignment plate having holes corresponding to the predetermined pattern is mated to the carrier plate with its holes aligned with the predetermine pattern on the substrate. Solder balls are loaded into each hole of the alignment plate. The solder balls may be loaded with a vacuum plate which uses vacuum to pick up solder balls in the predetermined pattern and place them over the holes on the alignment plate. The vacuum is released for dropping the balls in the holes of the alignment plate. Alternatively a shutter plate having holes corresponding to the holes on the alignment plate is fitted on the alignment plate and afforded slidable movement between an offset position and an aligned position. A ball is loaded in each hole in the shutter plate when it is in its offset position. The shutter plate is then slid its aligned position wherein its holes are aligned with the holes on the alignment plate causing the balls to drop into the holes on the alignment plate and onto a conductive pad of the substrate.
