Electronic transformer/inductor devices and methods for making same

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. In another preferred embodiment, a series of thin, concentric high ...

[Also in Division G4] In a matrix memory array, the drive and sensing windings are each arranged in groups in different ways thereby reducing noise effects in a sensing operation. Drive plane circuits are divided into a plurality of groups along different lines from the division lines of the sensing plane circuits. The memory described, Fig. 1, is a 3-dimensional array of apertured ferrite plates divided into four quarters by an A-B division plane for the sense circuits and a G-H division plane for the drive circuits. As shown in Fig. 1, the memory is further divided into 16 sub-modules arranged in four modules 1-4 forming four horizontal layers. Each Y drive winding, such as that between terminals 28, 29, Fig. 2, extends through only one half of the array and further is itself arranged in two halves in staggered vertical planes in the A and B halves ...

Method and apparatus to inhibit bubble formation in a fluid

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. The invention also encompasses a method for inhibiting bubble formation during a chemical reaction using the aforementioned apparatus.
