Abstract:
A recharge apparatus for holding the rechargeable device and battery includes the cradle top and the cradle base. The cradle top includes the elastic gate, the battery-fixing clip, and the charge area. The elastic gate is an opening for inserting the rechargeable battery, and capable of rebounding against pressure so that the elastic gate does not clip the user's finger during operation, and also enhances the appearance as well as being dust-proof. The battery-fixing clip is used for clipping the rechargeable battery tightly. The charge area is an inserting area for charging the rechargeable devices, and has a stand pin to hold the rechargeable devices steadily by inserting the stand pin into the bottom of the rechargeable device. The cradle base assembled with the cradle top includes the elastic joint and recharge PCB (printed circuit board). One end of the elastic joint is designed as the upward curve to touch the rechargeable battery. When the rechargeable battery is inserted to recharge, the elastic joint is pressed downward, resulting in an upward rebounding force. In this way, the rechargeable battery is connected to the recharge PCB via the elastic joint.

Abstract:
A circuit structure is provided. The circuit structure includes a capacitor including a top capacitor electrode; a bottom capacitor electrode parallel to the top capacitor electrode; and an insulating layer between the top and the bottom capacitor electrodes. The insulating layer includes a dielectric rod enclosed by a dielectric material. The dielectric rod has a higher dielectric constant than that of the dielectric material. The circuit structure may be a printed circuit board or packaging substrate, wherein the capacitor is formed between the two layers of the capacitor. Additional dielectric rods may be formed in the insulating layer of the capacitor and spaced apart from the dielectric rods.

Abstract:
The present invention relates to a an on-chip inductor structure and a method for manufacturing the same. The an on-chip inductor structure according to the present invention comprises a substrate, a porous layer, a plurality of conductors, and an inductor. The porous layer is disposed on the substrate and has a plurality of voids; each of the plurality of conductors is disposed in the plurality of voids, respectively; and the inductor is disposed on the porous layer. Because the plurality of conductors is used as the core of the inductor, the inductance is increased effectively and the area of the an on-chip inductor is reduced. Besides the manufacturing method according to the present invention is simple and compatible with the current CMOS process, the manufacturing cost can be lowered.
