A tripod type constant velocity joint comprises a housing having three track grooves defined at trisected positions of the housing and extending in an axial direction, and a spider having three -trunnions projectedly formed at trisected positions of the spider to be respectively inserted into the track grooves, each trunnion having a generally oval or elliptical cross-sectional shape and including at least one independent contact surface at each of two opposing sides subjecting to a load. Inner rollers each has an inner surface of a concavely curved contour for receiving a corresponding trunnion therein, and an outer roller is mounted to each inner roller with a plurality of needle rollers engaged there-between.

A RF transceiver for AMPS communication includes: a baseband processor for generating a transmission intermediate frequency signal and processing a reception intermediate frequency signal; a local oscillator for generating a local oscillation signal in transmission and reception; an up-mixer for combining the transmission intermediate frequency signal with the local frequency signal; a duplexer for processing a radio frequency signal received through an antenna; and a specific frequency removing unit installed between the local oscillator and an up-mixer to remove a specific frequency signal generated from the local oscillator. A filter is installed between the local oscillator and the up-mixer to remove the 2-times frequency of the local oscillation signal of 957.66 MHz, thereby removing the self-quieting phenomenon generated in the channel 76 of AMPS.

Provided is a high joint angle tripod type constant velocity joint, which can increase a maximum joint angle amount and can make an outer roller have a relatively small width by forming a protrusion on a circumferential outer surface at a top end of an inner roller, thereby maximizing a vertical movement range of the inner roller while preventing the outer roller from being released, and which can reduce the manufacturing cost by reducing the number of components.

Articles of silicon nanowires were synthesized on metal substrates. The preparation minimized the formation of metal silicides and avoided the formation of islands of silicon on the metal substrates. These articles may be used as electrodes of silicon nanowires on current collectors.

The self-assembly of polyhedral nanostructures having at least one dimension of about 100 nm to about 900 nm with electron-beam lithographically patterned surfaces is provided. The presently disclosed three-dimensional nanostructures spontaneous assemble from two-dimensional, tethered panels during plasma or wet chemical etching of the underlying silicon substrate. Any desired surface pattern with a width as small as fifteen nanometers can be precisely defined in all three dimensions. The formation of curving, continuous nanostructures using extrinsic stress also is disclosed.
