摘要:
A Miniature Remote Control System (10) that overcomes the problems encountered by previous remote control devices is disclosed. The present invention uses a remote emitter (12) which integrates a radio transmitter circuit (60) in a small housing (34) that plugs into an existing lighter receptacle (28) in a vehicle (V). When pushed down, the remote emitter (12) transmits a coded serial pulse train (16) to a remote receiver (14) up to 200 feet away. The pulse train (16) has a unique code (20) (one of 19,683) on a 380 MHz carrier frequency. The remote receiver (14) processes the pulse train (16), and extracts the serial transmitter code (20). The transmitter code (20) is then compared to the preset receiver code (22), and, if a match is found, a relay (104) is triggered. When activated, the relay (104) can be used to operate external devices (ED), including garage doors (GD), security gates (SG), burglar alarms (SA), exterior lights (EL) or interior lights (IL).

Three embodiments of MicroCube Interconnection Hardware are disclosed: the MicroVac Vacuum Generator, the MicroControl Module, and the MicroSensor. Each embodiment is a combination of a MicroCube Precision Fitting and Various enhancements which provide precision control, regulation, or measurement of flows of gas or liquid in a semiconductor fabrication environment. The Microcube Precision Fitting is a substantially cubical unitary body that includes a central chamber and at least one external port. Each port comprises an annular counterbored step surrounded by a support wall which both enclose an aperture that extends into the central chamber. The MicroVac Vacuum Generator is a combination of a MicroCube Precision Fitting and three appendages: an inlet, a contaminant port, and an outlet. A first stage fits inside the inlet and is disposed coaxially to a second stage that resides within the outlet.

A Modular Bottle-Mounted Gas Management System (10) that overcomes the problems encountered by previous gas cabinet equipment is disclosed. The present invention comprises a complete gas manifold (22) that includes computer-controlled valves, actuators, regulators and transducers. The entire system resides within a housing (11) that sits atop a conventional gas bottle (12) that would normally be enclosed within a gas cabinet (25) that is many times the volume of the Modular Bottle-Mounted Gas Management System 10. Outside the housing (11), an upper control panel (13) contains an LCD display (14) and a lower control panel (15) holds a keypad control (16), a removable data pack (17), LED indicator lights (18), and an emergency shut-off switch (19). Inside the housing (11), a bottle neck (20) protrudes up from the gas bottle (12) and provides a connection for a supply of gas within it to a gas manifold (22). The gas manifold (22) is an assembly of valves, actuators, pressure regulators, welded fittings, and transducers. The top of the housing (11) is fitted with a process gas outlet (21a), a vent connection (21b), a nitrogen inlet (21c), and a bottle access cover (21d). The top portion of the hinged housing (11) may be swung open to provide access to the gas manifold (22). The present invention provides safe handling of toxic, corrosive, and pyrophoric gases in a double-containment vessel. It utilizes component-to-component welds (65) to allow for the absolute reduction of the size of the manifold (22) while simultaneously reducing the number of mechanical connections. This advanced design delivers unprecedented levels of cleanliness by minimizing the number of particulate traps within the manifold (22).

A Method for Supplying Industrial Gases Using Integrated Bottle Controllers that overcomes the problems encountered by previous gas cabinet equipment is disclosed. The present invention comprises a compact and virtually explosion-proof controller (10) that is anchored securely to the top of a standard gas bottle (12). The entire system resides within a housing (11) that sits atop a conventional gas bottle (12) that would normally be enclosed within a gas cabinet (25) that may be sixty times the volume of the present invention. The controller (10) includes a housing (11) that has a top or lid (14), an upper cylinder (16), an annular wall (18) which forms a seal with the bottle (12). In a preferred embodiment of the invention, filled and cleaned bottles are connected to controllers at a fabrication clean area. The controllers are then operated remotely using a radio frequency or infra-red control. After the bottles are depleted, the controllers are removed and tested. The bottles are then refilled for reuse.

A MicroMount™ System for providing reliable, self-aligning connections to external fluid-handling or fluid-sensing components is disclosed. One embodiment comprises a generally miniaturized rectilinear body (102) that includes a plurality of exterior side walls (103). The upper wall (104) has a port (108) which is configured to connect to an external component. The end of the same port (108) which extends to the lower wall (105) is connected to an external passageway (107). The rectilinear body (102) does not require holes or fasteners that fit into holes, since it employs a number of posts (110) that project from the body (102) to secure the body (102) to an external component.

The invention is extremely useful as part of an integrated CNC Machining System.
摘要:
A method of arc welding is disclosed. Specifically, a method of pulsed direct current (DC) arc welding is disclosed wherein special pulses of positive direct current are used to weld together work pieces. The special DC pulses are capable of dissipating difficult to reduce oxides which may be present on the surfaces of the work pieces without using a flux. The method is especially useful for fluxless arc welding of aluminum, particularly thin wall aluminum tubing used in making heat exchangers for air conditioning systems.
摘要:
An orbiting welding head for welding tubing and the like together. A U-shaped tube clamp unit has a pair of jaws in which two tubing sections to be welded together are held with the edges of such tubing sections in abutment against each other. A welder unit is incorporated in a cassette having a housing with an electrically non-conductive outer wall portion. This cassette is inserted into the U-shaped tube clamp and removably joined thereto by means of a locking ring. The welder unit has a welding electrode which protrudes from a horseshoe shaped rotatable electrode drive member. This drive member has a ball bearing support which comprises a plurality of ball members which protrude from the rotatable drive member at the opposite side faces thereof and which ride in respective grooved races formed in the main body of the cassette. The drive member is rotatably driven by means of a motor driven gear train. The welding electrode is thus rotatably driven around the interface between the tube sections to be joined together in effecting the welding operation.
