    Abstract: A bifunctional compound containing an amino group and diaminedithiol ligand and a manufacturing method thereof are revealed, the bifunctional compound includes at least one amino group and a diaminedithiol (N2S2) ligand. The amino groups is for reacting with compounds containing carboxylic acids or halogens while the N2S2 ligand binds with technetium or rhenium so as to form an anion complex. The thiol group in the N2S2 ligand is protected by a protecting group for prevention of oxidation and easy storage. This protecting group is released easily during complex reactions. Due to the bifunctional property, the compound is applied to preparation of radiopharmaceuticals such as imaging agents and targeted agents.

Thus, the volume of the bicycle is further reduced to become more compact and to save cost. Transmission units are provided respectively at both sides of the bottom, which are independently operated and include pedals moving up and down. Freewheels are provided respectively at both sides of the rear wheel of the bicycle body, and the transmission units at both sides are respectively connected to the freewheels. Not only the structure is simple for easy assembly, but also the volume after folding is very small for easy carry. A number of speed change points can also be provided on each transmission unit to increase the stroke of the freewheel so that the goal of speed change can be achieved.

  • Publication number: 20100254239
    Abstract: The present invention relates to a method for calibrating a focus position of an optical pick-up. The optical pick-up is located on a focus position at a preset distance from a recordable optical medium to emit a recording beam of a preset power to the recordable optical medium so that corresponding optical data are recorded in the recordable optical medium. The method includes: altering a focus position of the optical pick-up during a recording process to generate a corresponding write radio frequency (RF) signal; detecting a minimum value of the write RF signal and a corresponding object focus position; and moving the optical pick-up to the object focus position so that the optical pick-up performs recording at the object focus position in the recordable optical medium.

  • Publication number: 20100251994
    Abstract: An improved remote control model engine assembly includes an engine body, a cylinder and a crane shaft chamber. A piston and a piston link rod are pivotally installed in the cylinder. The crane shaft chamber is horizontally and pivotally coupled to a crane shaft, whose end is connected to the bottom of the piston link rod for performing linking and rotating operations. A passage is concavely disposed at a middle section of the crane shaft corresponding to an air intake opening and penetrated axially through the crane shaft chamber. The passage is pivotally and axially coupled to a vane wheel by coaxial rotation, such that a high-speed operation of the crane shaft produces a powerful guide suction in the passage to suck a mixed petroleum gas into the crane shaft chamber and an internal upper space of the cylinder to enhance the igniting explosion effect and the horse power output.
