International Classification:

H01F017/04

US Classification:

336233, 336177, 336200, 336219, 336232

Abstract:

This invention describes materials system and processing conditions for manufacturing magnetic circuit components such as induction coils and transformers that are non wire-wound, miniature in size and, have a low manufacturing cost. The materials system of this invention is comprised of: (1) Low Temperature Cofire Ceramic (LTCC) tapes or thick film pastes of ferromagnetic ceramics with a 20 to 750 range of magnetic permeability to form the magnetic core of the components, (2) Thick film buried silver conductor paste to form the planar induction coils on individual magnetic layers, (3) Thick film via-fill silver conductor paste to interconnect two or more of the planar induction coils through the thickness of the magnetic layers, (4) Thick film silver solderable top layer conductor paste compatible with the ferrite and, (5) Thick film dielectric paste with low magnetic permeability to redirect the magnetic flux for enhancing the magnetic coupling coefficient and to insulate the silver conductors for enhancing the dielectric breakdown voltage. The key characteristics of the materials system of this invention that facilitate manufacture of low cost non wire-wound, miniature magnetic circuit components are: (1) Mutual compatibility essential for either of the techniques, the cofire technique or the sequential technique, used for manufacturing multilayer hybrid microelectronic components, (2) Complementary thermo-physical properties such as shrinkage and thermal expansion coefficient essential for manufacturing flat multilayer magnetic components, (3) Magnetic components with magnetic coupling coefficients greater than 0. 95 under optimal processing conditions and, (4) Magnetic components with dielectric breakdown voltage greater than 500V/mil under optimal processing conditions.

International Classification:

A43C015/00

US Classification:

036/05900R

Abstract:

A shoe including an upper, a lower (insole) attached to the upper, and an outsole attached to the lower is presented. In one embodiment, the outsole has a ground contacting surface which includes a first section and a second section, with the first section being formed of a first material and the second section having an outer later formed of a material other than leather, rubber or plastic. The first section can be formed of any number of materials, such as rubber, leather, etc. The first and second sections of the outsole are formed in an injection molding processes that uses one or more molds.

US Classification:

224577, 2207, 220911, 2159, 2252

Abstract:

An article of apparel is convertible into a travel pillow and includes an elongated scarf having opposite end regions, a pair of open pockets at the end regions, and a pair of gloves receivable in one of the pockets when not worn on a wearer's hands. A hat is optionally receivable in the one pocket when not worn on the wearer's head. The scarf is foldable onto itself by being folded or rolled from the other of the pockets towards the one pocket to form folded scarf portions. The folded scarf portions are receivable in the one pocket, together with the gloves and optionally the hat, for joint compact storage, or for use as a travel pillow in which the folded scarf portions, the gloves, and optionally the hat, stuff and plump the pillow.

Inventors:

Michael Stein - Yardley PA

Assignee:

E. S. Originals, Inc. - New York NY

International Classification:

A43B 312

US Classification:

36 115

Abstract:

A sandal includes a pair of heel posts on a sole, a heel strap between the heel posts, a toe post on the sole, an adjustable toe strap, and an adjustable cinch strap attached to the toe post. The cinch strap has a longitudinal portion which extends longitudinally through a heel cinch on one of the heel posts, and a transverse instep portion which thereupon extends transversely through a heel cinch on another heel post. The adjustable toe and cinch straps ensures a secure, custom fit.

Appl. No.:

9/381494

Inventors:

Michael Alan Stein - King of Prussia PA

Assignee:

Electro-Science Laboratories, Inc. - King of Prussia PA

International Classification:

C03C 3076

US Classification:

501 55

Abstract:

The present invention relates to thick film coating compositions which adhere particularly well to silicon nitride substrates and accordingly may be used in the manufacture of heater apparatus using such substrates. Such thick film coating materials comprise a borosilicate glass matrix containing an amount of a metal oxide sufficient to enable said thick film coating material to react with a silicon nitride substrate to promote adherence thereto; and desirably further contains ceramic powders and/or metal or metal-containing compound powders and/or flakes.
