An antenna element comprises one or more directors, a resonator, and a three dimensional ground assembly. Parts of the antenna element are arranged on three metal layers. A top layer has an unconnected metal bar which forms a beam director, a resonator and a top part of the ground assembly. The resonator is an integral piece substantially in the form of a loop connected to a feed line and a feed line terminal ending. The feed line terminal ending serves as the ground plane for the feed line as well as providing impedance matching from the external transceiver circuit to the resonator. The ground assembly includes a top layer ground connected to a plurality of metallized half cylindrical hole channels (or metallized via holes) which connect to a ground terminal in a bottom layer.

A mobile phone hand-free extension device includes a FM radio transmitter with an active frequency searching circuitry to utilize a vehicular FM radio receiver for reproducing the audio signals from the mobile phone. The active frequency searching circuitry in this invention automatically detects which frequency band the vehicular FM radio receiver is currently using and set the RF frequency of the FM transmitter to the detected frequency. The FM transmitter relays the audio signals from the mobile phone by transmitting the audio signals through radio wave to the vehicular FM radio receiver to be reproduced by the speaker of the receiver.

A memory device with composite contact plug and method for manufacturing the same. The composite contact plug comprises a first insulating layer deposited on a semiconductor substrate. A contact hole is formed to penetrate through the first insulation layer. A barrier layer is deposited in the contact hole and fills a portion of the contact hole. A contact plug is formed on the barrier layer and fills the contact hole. The first insulating layer is etched back until the surface of the first insulating layer is below the contact plug. A diffusion barrier layer is then deposited on the first insulating layer and the contact plug. The diffusion barrier layer is planarized until the contact plug is exposed to form a composite contact plug. The memory device is constructed on the composite contact plug.

A method for fabricating semiconductor memory cells such as dynamic random access memory (DRAM) and ferroelectric random access memory (FRAM) with improved contact between the capacitor electrode and the underneath device area. It includes the following main steps of: (1) forming a first dielectric layer on a wafer surface; (2) forming at least one through opening in the first dielectric layer; (3) forming a ruthenium based plug in the through opening; and (4) forming a capacitor in contact with the ruthenium based plug. The ruthenium based plug can be made of ruthenium metal, conductive ruthenium oxide, or a stack of conductive ruthenium oxide and ruthenium metal. The method allows the memory cell to be made without the need for a barrier, which is required to protect the storage electrode from reacting with Si atoms during the fabrication process.

A game racket comprises a head, a shaft and a handle. The head is provided with a ball-striking surface comprising at least an elastic covering area which forms respectively on both sides of the ball-striking surface a covering plane serving to enhance the ball controllability of the ball-striking surface. The elastic covering area also serves to prevent the strings, which make up the ball-striking surface, from moving aside by a force of a ball impacting the ball-striking surface. The elastic covering area further serves the purpose of absorbing the shock wave generated by the impact of a ball on the ball-striking surface.
