International Classification:

US Classification:

438783, 438784

Abstract:

A method for making an anisotropic dielectric layer includes the steps of: forming a fluid layer comprising a plurality of magnetizable particles, for example, in a fluid capable of solidifying to fix the configuration of the magnetizable particles in a dielectric matrix; aligning the magnetizable particles of the fluid layer in a predetermined configuration by applying a magnetic field thereto; and fixing the aligned magnetizable particles in the predetermined configuration within the dielectric matrix by solidifying the fluid. In one particularly advantageous application, the fluid layer is coated onto a surface portion of an integrated circuit, such as a fingerprint sensor, to provide mechanical protection without effecting the image resolution. In addition, the step of aligning for certain devices preferably comprises aligning the magnetizable particles in a predetermined configuration so that an impedance perpendicular to the anisotropic dielectric layer is less than an impedance parallel to the anisotropic dielectric layer. The magnetizable particles may be mixed in a curable polymer fluid, and the step of fixing the aligned magnetizable particles may comprise curing the curable polymer fluid, such as by applying heat or radiation.

Abstract:

A method for densifying a dielectric antiferroelectric material includes the steps of adding a compound which includes lithium to the dielectric material to create a mixture thereof. Thereafter, the mixture is heated to a temperature of not greater than about 1100. degree. C. for a predetermined period to densify the mixture. It is preferred that the lithium compound be a lithium salt and that the dielectric material comprise a PLZT composition.

International Classification:

US Classification:

106 119

Abstract:

It has been newly determined that in a reaction of an Ag/Pd metallization with Pb from a lead-based ceramics, a maximum solubility of Pb is observed of approximately 14% (atomic percent). By inclusion of an effective amount of Pb in the Ag/Pd metallization, leaching of Pb from a Pb-based ceramic is either reduced or eliminated. Thus, upon firing, the metallization exhibits an equilibration which prevents Pb from being drawn out of the underlying ceramic. Similarly, Ag/Pd metallization shows a maximum solubility of 16 atomic percent for Bi in Bi-based ceramics. Inclusion of an effective amount of Bi in the metallization prevents a Bi leaching from an underlying ceramic.

Abstract:

A piezoelectric fluid pumping apparatus includes pumping means for supplying a fluid under pressure and an energizer arranged in driving relationship therewith. The energizer includes a generally planar flexure member having first and second piezoelectric laminates supported thereon. The flexure member includes a first edge and a second edge, the edges being resiliently constrained for substantially preventing longitudinal movement thereof when an electrical signal is applied to the laminates. Preferred embodiments of the flexure member include bimorphous, biunimorphous and quadrimorphous piezoelectric structures.

Abstract:

Long term culture of resting T lymphocytes. The present invention provides methods and compositions for maintaining resting, mature T lymphocytes (cells) for long term in the absence of mitogens, antigens, or stimulatory cytokines, in which the T cells maintaining their ability to respond to nitrogens and allogenic cells. T cells cultured under such conditions can be used as target cells for retroviral vector-mediated gene transfer and implemented in certain gene therapy applications. The culturing conditions described herein allow for the continuous availability of T lymphocytes for various pharmacological, diagnostic, gene therapy, and experimental purposes, and can be utilized for any application requiring non-stimulated T lymphocytes. In specific examples, umbilical cord blood and peripheral blood T lymphocytes and endothelial-like adherent monocytes are cultured in DMEM, 2% 2-mercaptoethanol containing either 20% horse serum, or RPMI 2% 2-ME containing 10% fetal calf serum supplemented with basic fibroblast growth factor for up to three months.

A cardiac defibrillator includes a multilayer capacitor with a plurality of conductive electrodes and interspersed dielectric layers, each dielectric layer composed of constituents which cause it to exhibit an antiferroelectric phase. The constituents of each dielectric layer are such as to cause each layer to exhibit plural ferroelectric phases. The defibrillator includes a charging circuit for applying to the capacitor an electric field across each dielectric layer which causes a transition thereof through the plural ferroelectric phases. PLZT is the preferred dielectric material, at constituent values which cause the material to lie within the antiferroelectric phase and to exhibit plural ferroelectric phases.

A cardiac defibrillator which incorporates the invention hereof includes a multilayer capacitor with a plurality of conductive electrodes and interspersed dielectric layers, each dielectric layer composed of constituents which cause the dielectric layer to exhibit antiferroelectric characteristics. The defibrillator includes a charging circuit for applying to the capacitor an electric field across each dielectric layer that is at least equal to E. sub. f, where E. sub. f is a field value that enables the dielectric layer to transition to a ferroelectric phase. A preferred dielectric material comprises lead, lanthanum, zirconium and titanium, all at constituent values which cause the resulting ceramic material to lie within the antiferroelectric region.
