Abstract: Slot core inductors and transformers and methods for manufacturing same including using large scale flex circuitry manufacturing methods and machinery for providing two mating halves of a transformer winding. One winding is inserted into the slot of a slot core and one winding is located proximate to the exterior wall of the slot core. These respective halves are joined together using solder pads or the like to form continuous windings through the slot and around the slotted core.

Abstract: A gas generation system includes a chemical reactor integrated with a liquid/gas separator. The reactor is configured to receive a continuous stream of aqueous solution.

Abstract: The invention relates to an apparatus for inhibiting bubble formation during a chemical reaction. The apparatus comprises a base having a substantially planar surface with at least a portion of the surface representing a fluid contact area and a fluid comprising a liquid component in contact therewith. A cover and the base form an enclosure containing the fluid and a gas. A non-free-floating fluid-distribution member is provided that has a substantially flat surface in contact with the fluid. The member surface is disposed in an opposing and substantially parallel manner at a specified distance from fluid contact area. A gas-fluid interface having an interface radius is formed between the fluid and the gas. The apparatus also comprises means for maintaining a desired vapor pressure of the liquid component in the gas and means for immobilizing the cover with respect to the base. The interface radius is selected to result in a predetermined critical radius below which a bubble will shrink.

Abstract: The present invention relates to the methods of construction for inductive components of, preferably, ferromagnetic materials such as inductors, chokes, and transformers when used as an integral part of the fabrication of PCB's or FLEX's. In one preferred embodiment, holes are formed through a ferromagnetic substrate and plated with conductive material. The arrangement of these holes, and the subsequent design that ensues, will form the inductive components within the plane of the media in which the device is formed; using the substrate for a magnetic core. By using this approach, the inductive components can be miniaturized to physical sizes compatible with the requirements of modem surface mount technology (SMT) for integrated circuitry (IC). This process also allows these components to be fabricated using mass production techniques, thereby avoiding the need to handle discrete devices during the manufacturing process.

Abstract: A method is disclosed for accurately registering read-write heads on a magnetic storage medium. It includes the steps of ascertaining fractional departures of track locations from the nominal locations; providing a control for a motor connected to move a read-write head capable of detecting and storing fractional values of the nominal channel spacing; and coupling the control digitally to a stepping motor or servomotor so as to drive the read-write head accurately to the actual position of any selected track. Also, apparatus for practicing the method, various apparatus being disclosed.
