  • Patent number: 8748848
    Abstract: A method of generating Raman laser for inducing fluorescence of fluoranthene and a system thereof is disclosed. The system comprising a pulsed laser, a frequency doubling crystal, a frequency quadrupling crystal, a light filter unit, a quarter-wave plate, a Raman cell filled with deuterium gas( ), a light dispersion device and an optical diaphragm. The method of the present invention comprises the steps of emitting a laser beam pulse through the crystals as mentioned above such that a mixture of lasers is generated. The light filter unit and the quarter-wave plate are used to obtain a circular or ellipsometric polarized pump laser from the mixture of lasers. Finally, the Raman laser is obtained by directing the pump laser into a Raman cell filled with deuterium gas, extracting different orders of stimulated Raman scattering lasers emitted from the Raman cell by the light dispersion device and selecting the desired order of stimulated Raman scattering laser by the optical diaphragm.

  • Patent number: 8609137
    Abstract: The present invention discloses a novel soft capsule of butylphthalide and a process for preparing the same. The soft capsule of butylphthalide is composed of a capsule wall material and a drug-containing oil, wherein the drug-containing oil is essentially composed of butylphthalide and a vegetable oil as the diluent in a weight ratio of about 1:0˜10. The capsule wall material is composed of a capsule wall matrix, a plasticizer and water in a weight ratio of 1:0.2˜0.4:0.8˜1.3. The soft capsule of butylphthalide described in the present invention can mask the strong and special flavor of butylphthalide, and overcome the difficulties associated with formulating oily active ingredient into other oral formulation. The disintegration time of the soft capsule satisfies the requirement of Pharmacopoeia of P.R. China.

  • Patent number: 7446643
    Abstract: An electrical protection system, which can be connected between an electrical power supply and an electrical load, firstly includes a switch switchable between a normal state in which the switch is electrically connected in series between the power supply and the load such that an operating current passes through the switch and the load, and a fault sate in which the switch is disconnected with the load such that no current passes through the load. The switch switches to the fault state in an over-current or an over-temperature situation.
