Abstract: A gear box may have a housing and a driving shaft with a gear and a driven shaft with a gear. The shafts may be rotatably mounted in the housing and positioned so that the driving shaft gear meshes, i.e., is in operable position, with the driven shaft gear. An eccentric bearing adjust may be positioned to surround a part of the driving shaft (or a part of the driven shaft). A first and second tip set screws may be positioned in the housing in operable position to the eccentric bearing adjust. The first and second tip set screws are configured to rotate the eccentric bearing which moves a center position of the driving shaft (or a center position of the driven shaft) when the screws are tightened or loosened. Rotating and calibrating the eccentric bearing adjust mitigates any backlash between the driving shaft gear and the driven shaft gear.

Abstract: The present invention is a transfer arm that moves a wafer inside a piece of equipment designed to manufacture electronic circuits. The transfer arm has a hand, used to securely hold the wafer using Bernoulli's Principle. The transfer arm has a left wrist and a right wrist connected to the hand, wherein the hand and the left wrist and the right wrist comprise sealed gears and sealed bearings. A left upper arm is connected by being threaded to the left wrist and a left elbow and a right upper arm is connected by being threaded to the right wrist and a right elbow. A left lower arm is connected by being threaded to the left elbow and the left shoulder and a right lower arm is connected by being threaded to the right elbow and the right shoulder.

Abstract: A system for mitigating risk in an enclosed space comprises: a processor unit having a rules engine and a workflow engine; an infrastructure library accessible by the processor unit and holding a plurality of available interventions which can be enacted by the system; a plurality of environmental sensors, each arranged to supply the processor unit with sensor signals indicating a sensed risk factor of the enclosed space; a workflow interface arranged to instruct the operation of a workflow which enacts an intervention; wherein the rules engine is configured to process the sensor signals from the plurality of sensors against a set of rules to determine if the risk is elevated to a level where mitigating action is required; wherein the workflow engine is configured to select one or more of the available interventions from the infrastructure library when intervention is required; wherein the processor unit is configured to generate a workflow instruction signal when a workflow has been selected and to send that

Abstract: The present invention generally relates to an injector for a semiconductor fabrication tool for dispensing a material into an interior volume of the fabrication tool during a fabrication process of a semiconductor wafer. The injector may have a micrometer that may be adjusted so as to totally stop the flow of material through the injector or the micrometer may be adjusted to allow a range of precisely controlled flow rates of material through the injection. The injector is also preferably able to be easily taken apart and cleaned in the field, thereby increasing the injectors useful lifetime.

Abstract: An exhaust conduit having a wall with an inner surface that at least partially defines a flow channel, a first fin positioned within the flow channel and attached to the inner surface, a second fin positioned within the flow channel and attached to the inner surface such that the first fin is spaced apart from the second fin. A support strip is attached to the inner surface, attached to the first fin at a first location spaced apart from the inner surface, and attached to the second fin at a second location spaced apart from the inner surface.
