This invention relates to a controlled-release combination drug product comprising troglitazone, e.g. its hydrochloride, and a biguamide, e.g. metformin. In particular, the product comprises a core of metformin, at least a portion thereof has a layer or coat thereon of troglitazone.

Disclosed is a core for use in a core-board, which consists of an embossed sheet of a light weight material comprising a central surface extending in a plane and a plurality of embossments called top and bottom cells, that are identical in shape and project from the central surface on both sides thereof. Each of the top and bottom cells is integral to the central surface and of pyramidal shape. Each of them also has an open base of regular hexagonal shape extending in the plane of this central s...

A magnetic core is obtained by winding or laminating at least one alloy ribbon and has excellent squareness characteristic and magnetic saturation characteristic in a high frequency region wherein the squareness ratio of the magnetic core is improved by restricting the surface roughness of the alloy ribbon to specific regions.

A moulded armature core comprises a moulded cylindrical block of magnetic material, having a plurality of slots disposed in parallel along the peripheral portion thereof in a manner to extend lengthwise of the block, said slots being so tapered as to progressively decrease in both depth and width.

A high-current-carrying, flexible electric cable has a central hollow core having longitudinal flutes along its exterior, conductors surrounding the core, and sheathing encasing the conductors. The core has an internal restriction adjacent to each end which permits limited flow of liquid through its hollow interior and has a perforated portion adjacent thereto toward each end of the conductor in order that liquid introduced into the core will be forced through the perforations into the interstic...

A core drill structure comprises a hollow shaft to which an annular drill head is secured, the drill head including a plurality of equispaced recesses for receiving plates provided with alternatively usable cutting edges for drilling an annular hole. The cutting edges of the plates are respectively staggered in a radial direction so that each cutting edge works only a portion of the width of the annular cut, and these cutting edges are also disposed respectively in different planes normal to the...

A lightweight high efficiency radiator core having a plurality of cylindrical metal tubes, and a plurality of fins with fin openings and fin collars fitting around the tubes in tight metal-to-metal contact, header plates having openings with collars, and grommets located in said header plate openings and fitting around the collars, the tubes being force-fitted through the grommets, and a method of assembling such a radiator core, by means of passing tubes through the fin collars, and thereafter ...

A magnetic core comprised of an amorphous alloy ribbon wound into a toroidal shape, wherein the said amorphous alloy has a composition of the formula: wherein M is at least one element selected from the group consisting of Nb, Cr and Mo, and x, y, z, a, b and c are numbers which satisfy relations of 0<a.ltoreq.6, 13.ltoreq.b.ltoreq.16, 7.ltoreq.b.ltoreq.10, 0<x.ltoreq.0.1, 0.ltoreq.y.ltoreq.0.2 and 0.ltoreq.x.ltoreq.0.13 respectively, said amorphous alloy after heat treatment having a rect...

A magnetic core is obtained by winding or laminating at least one alloy ribbon and has excellent squareness characteristic and magnetic saturation characteristic in a high frequency region wherein the squareness ratio of the magnetic core is improved by restricting the surface roughness of the alloy ribbon to specific regions.

In the magnetic core including a first leg portion around which a wire is wound, a second leg portion for circulating a magnetic flux generated in the first leg portion, and a web portion connecting the first leg portion and the second leg portion, a magnetic gap is provided in a rear area extending from the root of the first leg portion. With the magnetic gap, a magnetic flux leaking outwardly from a rear area extending from the root of the first leg portion is drastically reduced.
