Abstract:
A multilayer electronic structure comprising a plurality of layers extending in an X-Y plane consisting of a dielectric material surrounding metal via posts that conduct in a Z direction perpendicular to the X-Y plane, wherein at least one multilayered hole crosses at least two layers of the plurality of layers and comprises at least two hole layers in adjacent layers of the multilayer composite electronic structure, wherein the at least two holes in adjacent layers have different dimensions in the X-Y plane, such that a perimeter of the multilayered hole is stepped and where at least one hole is an aperture to a surface of the multilayer electronic structure.
Abstract:
The atypical antipsychotic drugs (AAPDs) have markedly enhanced the treatment of schizophrenias but their use has been hindered by the major weight gain elicited by some AAPDs. We found that orexigenic AAPDs potently and selectively activate hypothalamic AMP kinase (AMPK), an action abolished in mice with deletion of histamine H1 receptors. These findings afford a means of developing better therapeutic agents and provide insight into the hypothalamic regulation of food intake.
Abstract:
A connector for a flexible flat cable comprises a clamping seat provided at the front and rear ends thereof with an insertion, terminal recesses and a cover plate respectively, at each of the outer walls of two of the terminal recesses, which are located at the leftmost and rightmost sides, is formed a slot, and on the cover plate being disposed bores, at each of two sides of the clamping seat being arranged a retaining member, a locking member defined at the front end thereof with an inserting segment and snap-on tabs; wherein the retaining member is connected to the clamping seat by using a connecting portion in its intermediate projected section, and is provided at its front and rear ends with a hook and a bent end wall respectively, a groove is formed for spacing the retaining member and the outer side of the clamping seat apart, thereby achieving a secure retaining purpose and preventing the operational fatigue.
Abstract:
The catheter includes an inner column and an outer elastic member. The inner column is bendable wherein the column strength and flexibility of the inner column are adjusted by axially tensioning the outer elastic member. The inner column comprises a helical spring, slotted or slit tube, or individual links that, when axially compressed by advancement forces or by tensioning an elastic outer sheath, assume a straight or other pre-determined geometry. The column strength and flexibility of the catheter may be adjusted during introduction of the catheter into a body lumen as necessitated by the conditions encountered, as well as made highly flexible when left in position.
Abstract:
An adapter for a fluorescent is adapted to apply to cold cathode fluorescent tube on LED display and has a cover with two inner grooves and a switch portion having a track, a body slidably engaged with the cover, a metallic terminal stand attached to and controlled by the switch portion. The body has two rails correspondingly engaged with the grooves of the cover and has a recess for resting the fluorescent tube. The metallic terminal stand has two resilient arms close each other to perform a Y-shaped opening at distal ends and an oval expansion hole below the Y-shaped opening. When the cover is pushed to slide along the trail on the body, the track on the body with a narrow section presses abutting faces on the resilient arms and limits the expansion of the resilient arms on the metallic terminal stand so as to quickly and detachably clamp the fluorescent tube.
Abstract:
A soft wire bank joint device comprises a body and a joint connected to one end of the body; the body including: a first insulating layer; a conductive wire layer located above the first insulating layer; a second insulating layer located above the conductive wire layer; a silver shielding layer located above the second insulating layer; and a third insulating layer located above the silver shielding layer. The joint includes a top sheet, a bottom sheet and an insulating casing. One end of the body is installed on the bottom sheet; and the bottom sheet is installed on the insulating casing. The top sheet is coupled to the insulating casing. A length of the second insulating layer is equal to that of the silver shielding layer, but is shorter than that of the conductive wire layer. One side of the conductive wire layer projects out from the second insulating layer.
Abstract:
A soft PC board connector comprises a seat. A rear half of the seat has a plurality of through holes; and a front side of the seat is formed with a plurality of terminal slots. A plurality of front insertion elastic sheets each integrally formed with a hook portion. A plurality of rear insertion elastic sheets each rear insertion elastic sheet is integrally formed with a hook portion, a contact nose, an SMT welding pin, and a recess for embedding a soft bank wire or a soft circuit board. The rear insertion elastic sheet is inserted into the through holes. A movable cover is capable of covering upon the terminal slots of the seat. One long side of the cover has a plurality of notches. Each notch is passed by a shaft for being received within the hook portion of the front insertion elastic sheet.
Abstract:
A fixing structure includes an insulator, and multiple board locks. The insulator has multiple receptacles for mounting multiple conductors. The insulator has one side protruded with a chamfered latch boss, and has two sides formed with opposite recessed sockets each having a bottom side and an adjoining side formed with a substantially inverted T-shaped through hole. Each board lock includes an upper portion defining a substantially inverted U-shaped pivot portion, and a lower portion defining a forked insertion portion. Each of the pivot portion and the insertion portion has outer sides formed with outward protruded shoulders. The pivot portion has a middle formed with a flexible locking tab that is slightly protruded outward.
Abstract:
The present invention relates to a plastic housing structure of a board-to-board connector comprising a base seat and a top cap, wherein the base having a central protruded rib portion with a plurality of slots along the two lateral sides of the rib portion, a through hole being formed at the bottom portion of the slot and the external side of the slot being corresponding to a plurality of notches having a sloping guiding surface at the inner surface thereof, at the two ends of the rib portion, an engaging surface being provided for engagement with a top cap, and the top surface of the engaging surface being provided with a blocking block and a protrusion; and the top cap is provided with an engaging portion at the side thereof, and the bottom portion is provided with a plurality of protruded blocks having a wavelike surface at the inner side thereof, thereby, the base seat and the top cap are combined, and the protruded blocks are inserted into the notches. The guiding pins are urged by the recess and the wavelike surface such that the guiding pins will not dislocate in the soldering process to remove the plastic housing, the top cap is lifted up and the guiding pins are released, but the guiding pins are retained on the circuit board.
