  • Publication number: 20100248388
    Abstract: A plate for laser desorption ionization mass spectrometry comprising an electrically conductive substrate (1) covered with an array of spots of sintered nanoparticles (2) acting as a highly efficient sorbing phase, a very sensitive photo-reactive phase and an ionization device when covered by an organic matrix or by a hole conductor or electron donor instead of an organic matrix.

  • Publication number: 20100182803
    Abstract: A resonant converter equipped with a phase shifting output circuit includes a resonant circuit to receive input power and regulate to become at least one resonant power, a switch unit to switch an ON period for the input power to pass through the resonant circuit and a power transformation circuit to regulate the resonant power and output a transformed power. The resonant converter further has a primary output circuit and at least one secondary output circuit. The primary output circuit regulates the transformed power to become a primary output power. A resonant control unit captures a feedback signal from the primary output circuit and generates a resonant control signal. A phase shifting control unit receives the resonant control signal and regulate to become a phase shifting driving signal. The secondary output circuit is controlled by the phase shifting driving signal and provides a secondary output power.

  • Publication number: 20100165684
    Abstract: A power adapter to receive at least one AC input power and transform to DC primary output power includes a power factor correction circuit to receive the AC input power and modulate to become a modulated power, an isolation voltage step-down circuit connecting to the power factor correction circuit to modulate the modulated power to a modulated lower voltage power, a switch voltage regulation circuit connecting to the isolation voltage step-down circuit to receive the modulated lower voltage power, and a voltage stabilization circuit connecting to the switch voltage regulation circuit. The switch voltage regulation circuit sets a determined output level and regulates the modulated lower voltage power to become a determined power at the determined output level. The voltage stabilization circuit modulates the determined power to become the primary output power and supplies the primary output power to a primary output end.
