Abstract: An antenna structure includes a ground element, a first radiation element, a second radiation element, a third radiation element, and a nonconductive support element. The first radiation element is coupled to a first grounding point on the ground element. The second radiation element has a feeding point. The second radiation element is adjacent to the first radiation element. The third radiation element is coupled to a second grounding point on the ground element. The third radiation element is adjacent to the second radiation element. The first radiation element, the second radiation element, and the third radiation element are disposed on the nonconductive support element. The second radiation element is at least partially surrounded by the first radiation element. The third radiation element is at least partially surrounded by the second radiation element.

Abstract: A PVD reactor with a function of alignment in covering an upper cover includes a cavity having a first contact surface; an interior of the cavity having a metal isolation plate; an upper cover pivotally installed to the cavity; the upper cover having a second contact surface which is positioned corresponding to the first contact surface of the cavity; the upper cover being capable of being combined with a target; a plurality of semi-spherical recesses in the first contact surface of the cavity; and a plurality of semi-spherical protrusions in the second contact surface; when the upper cover covers upon the cavity, the plurality of semi-spherical protrusions will embed into the plurality of semi-spherical recesses.

Abstract: A vapor reduction device for a semiconductor wafer has a plurality of heat plates which are spaced arranged longitudinally for receiving a plurality of wafers, the heat plates are integrated into a heating frame which is further placed into a casing. The movements of the heat plates within the casing causes that the wafers can be heated rapidly and uniformly so as to evaporated vapor effectively. The heat plates are separable from the heating frame and thus a number of the heat plates is selectable as desired. The heating temperature for the heat plates is controllable independently so that the temperatures of the wafers are controllable so that the temperature differences of the wafers are controllable to be uniformly distributed.

Abstract: An anode plate for a field emission display device (FED) is disclosed, which has a substrate; an anode conductive layer formed on the substrate; at least one interspacing conductive band having a plurality of internal gaps for connecting the anode conductive layer and external cable lines, wherein the interspacing conductive band covers a part of the anode conductive layer; and a fluorescent layer located on the anode conductive layer, to serve as a source of luminescence for a field emission display device. The field emission display device includes the anode plate aforesaid as is also disclosed.

Abstract: A position adjusting apparatus for a back of a stroller includes an engaging rod, a controlling slide member, and a positioning block. The positioning block is fixedly connected to at least one handle support rod of the stroller, and has several engaging protrusions each having a positioning gap formed adjacent thereto. The engaging rod is movably received in a lower tube portion of a frame of the back, and is connected to the controlling slide member movable along an outer side of the lower tube portion. A pivotal rod is connected to the positioning block and the lower tube portion, and passes through an elongated hole of the engaging rod to pivot the back frame on the positioning block. The engaging rod is biased by a spring to extend outward from the lower tube portion such that an engaging lower part thereof engages a selected one of the engaging protrusions to fix the back frame in position.
