In a light emitting device with a heat-release metallic part made of metal and a packaging ceramic part made of ceramics bonded to the metallic part via an adhesive, the adhesive is a hot melt that melts with heat at a melting temperature higher than a given temperature and has flexibility when it has been hardened and formed a bond, and the ceramic part has pores at least in a given bonding surface region so that the hot melt is impregnated into the pores.

The present invention provides a rotor of a brushless (BL) motor, including: a high-strength engineering plastic member formed by injection-molding high-strength engineering plastic around a concavo-convex portion 12a formed on the outer circumferential surface of a rotary shaft; a sound-absorbing resin element formed by injection-molding a sound-absorbing resin around the high-strength engineering plastic member; a cylindrical ring magnet assembly including a plurality of axially aligned ring-shaped magnets, each of which has a plurality of indented grooves 20a and 20b formed on both end edges of the inner circumferential surface thereof; and a high-strength plastic member formed by injection-molding a high-strength plastic between the sound-absorbing resin element and the ring magnet assembly, the high-strength plastic member having a plurality of protrusions formed on the outer circumferential surface thereof in such a fashion that each protrusion corresponds to an associated one of the indented grooves of the ring-shaped magnets.

A slurry composition for electrode comprising a binder, an active material, and a liquid medium, characterized in that the binder comprises a polymer (X) comprising 60 to 95 mole % of repeating units derived from acrylonitrile or methacrylonitrile and 5 to 30 mole % of repeating units derived from at least one kind of a monomer selected from 1-olefins and compounds represented by the following general formula (1): CH2═CR1—COOR2 wherein R1 represents a hydrogen atom or a methyl group and R2 represents an alkyl group; and the liquid medium is capable of dissolving the polymer (X). The slurry composition allows the manufacture of a lithium ion secondary battery having enhanced capacity and good charge-discharge cycle characteristics and good charge-discharge rate characteristics.

A light emitting diode having an adhesive layer and a reflective layer and a manufacturing method thereof featured by adhering together a light emitting diode stack and a substrate having a reflective metal layer by use of a transparent adhesive layer so that the light rays directed to the reflective metal layer can be reflected therefrom to improve the brightness of the light emitting diode.

The invention discloses a metal three-dimensional printing method and equipment thereof. The metal three-dimensional printing method comprises the following steps that melted and flowable metal or softened and flowable metal is put into a molding area used by three-dimensional printing equipment; after not having the flowability, the melted and flowable metal or the softened and flowable metal is converted into printed and molded metal; the melted and flowable metal or the softened and flowable metal is accumulated based on the printed and molded metal until an object to be printed is molded; the object to be printed is formed by the accumulated printed and molded metal. The key characteristics of the metal three-dimensional printing method disclosed by the invention lie in that during molding, binding force between layers and binding force between pixel points are changed in a manner of resistance radiation, and a printing area for performing resistance radiation can be set; a metal part generated by the metal three-dimensional printing method disclosed by the invention is high in strength, high in density, and high in molding accuracy; molding process of each pixel point is monitored; a dismountable assisting bracket can be synchronously generated; a large-scale part can be printed; the equipment is simple in structure and low in cost. The metal three-dimensional printing method and the equipment thereof disclosed by the invention have a substantive progress.

Providing two sheets which are opposed to each other, and a plurality of elastic elements each disposed between the sheets to extend along a stretchable direction of a composite stretchable member in such a manner as to be stretchable in the stretchable direction, wherein: the sheets are bonded together in a plurality of bonding sections, wherein each of the bonding sections is configured to continuously extend along a line intersecting the stretchable direction and to intersect the plurality of elastic elements; and each of the elastic elements is bonded to the sheets at intersection points with the bonding sections.
