Abstract: An electrodeposition process of platinum and platinum-based alloy nano-particles with addition of ethylene glycol is disclosed. An acidic solution which contains metal chloride includes at least one platinum-based chloride and the alloy thereof, and ethylene glycol are introduced into a reactor as an electrodeposition solution. By applying an external negative potential, platinum particles or platinum-based alloy particles are deposited on the substrate. The above acidic solution is able to provide ionic conductivity during electrodeposition. The added ethylene glycol effectively enhances the removal of chlorine from metal chlorides. Meanwhile, ethylene glycol is used as stabilizer to prevent the particles from aggregation onto the substrate, thereby increasing the dispersion of deposited particles.

Abstract: The present invention generally relates to an electroplating solution for manufacturing nanometer platinum and platinum based alloy particles and a method thereof. That is, an acid solution having platinum complex compound and citric acid is provided into a reaction tank to be as an electroplating solution, then a plurality of platinum and platinum based alloy particles are deposited on the surfaces of electrodes under the condition of applying negative potentials. The acid solution is capable of effectively providing the rate of conducting ions. The citric acid can effectively promote the dispersity of the platinum and platinum based alloy particles and reduce the dimensions the platinum and platinum based alloy particles.

Abstract: A process for growing a carbon nanotube directly on a carbon fiber includes at least the steps of depositing a metallic film of at least 1 nm in thickness on at least one surface of a flake-shaped carbon-fiber substrate; placing the substrate into a reactor; introducing a gas including carbon-containing substances into the reactor as a carbon source needed for growing a plurality of carbon nanotubes (CNTs); and thermally cracking the carbon-containing substances in the gas to grow the carbon nanotubes directly on the substrate.

Abstract: A stroller frame structure includes a front wheel rack, a rear wheel rack, a first linkage assembly, a coupling dock, a handle tube, a release mechanism, an armrest and a second linkage assembly that are pivotally coupled with one another. The handle tube has a lower end movable to allow the second linkage assembly to drive the first linkage assembly to move downwards to form a V-shaped folding thereby to move the front wheel rack and the rear wheel rack close to each other or extend to achieve smooth folding.

Abstract: A toys bracing bracket for mounting on a playpen or a play pad is detachable. It mainly includes a central pivot dock that has a first anchor section and a second anchor section to couple with a plurality of connection rods. Each of the connection rods is coupled with an elastic element so that the connection rods may be easily pulled and extended for mounting on the playpen or play pad, or be folded easily to facilitate carrying and storing, and to enhance safety.

Abstract: A frame structure for strollers includes a seat rack pivotally which is coupled with a front wheel bracket and a rear wheel bracket. The seat rack has a font seat bar and a rear seat bar that are pivotally coupled with each other. The rear seat bar is pivotally coupled with a sliding driving member, which may be driven to slide by a linkage member while the frame is folding to press the rear seat bar and fold the seat rack and also move the front wheel bracket and the rear wheel bracket close to each other to achieve smooth folding of the frame.

Abstract: A planar interdigitated microstrip coupler comprises a plurality of adjacently disposed transmission lines being spaced such that the transmission lines gradually diverge from a close spacing to a wider spacing. The planar interdigitated microstrip coupler provides equal power split and either 0.degree. or 180.degree. differential phase shift over a multi-octave bandwidth. Further, the interdigitated coupler, when used as a power combiner, provides increased cancellation of second order intermodulation products normally generated by non-linear devices, such as amplifiers, which may be fed to the inputs of the coupler. This increase in second harmonic cancellation, known for distorting signal fidelity, is particularly useful for monolithic circuit applications using amplifiers and mixers.

Abstract: A radio frequency amplifier includes a first pair of quadrature couplers arranged to provide in response to an input signal first and second radio frequency signals having equal amplitudes and a first single-ended amplifier is fed by said first radio frequency signal to provide at an output thereof an amplified first signal having frequency components corresponding to a fundamental frequency of the input signal and second order products of the input signal. A second single-ended amplifier is fed by said second radio frequency signal for providing at an output thereof an amplified, second signal having second order products of the input signal and 180.degree. phase shifter frequency of the input signal.
