  • Publication number: 20060238183
    Abstract: A power regulator has an output for regulated power that is connected to supply power to a load. The load can have various electrical characteristics, including requiring a rapid transient response. The transient response amplitude for the power regulator is decreased by adding capacitance at the output, but that slows the response time of the power regulator by lowering the crossover frequency and the phase margin at the crossover frequency. An adjustable gain element imbedded in the feedback network provides an input to permit a builder or user of the power regulator to vary the effective value of impedance elements in the feedback network. The builder or user selectively connects an impedance to the input of the adjustable gain element to thereby adjust the frequency characteristics of the feedback network to thereby adjust output characteristics of the power regulator to compensate for the effects of capacitance added to the power regulator output.

  • Patent number: 7088602
    Abstract: A DC-DC converter circuit includes a transformer with a resonate filter or snubber connected at a primary side and a switch for controlling operation of the converter. A secondary side of the transformer includes self-driven synchronous rectifiers and an output filter. Transistors are provided at the gates leads of the rectifiers and themselves are provided with a fixed voltage at their gates so as to clamp the peak voltages across to the rectifiers.

  • Publication number: 20060118687
    Abstract: A compact container holder that comprises a housing, a door, and at least one arm is provided. The arm can be linked to the door through a linkage that can also connect opposing dual pivots. The opposing dual pivots can allow the container holder to fully open and close in one controllable motion, providing a container holder that simply and reliably opens and closes.

  • Patent number: 6908674
    Abstract: A jadeite material has a thickness in excess of about 1.0 mm and CIELAB indices of L*>42, a*<?6, and b*>+6. The grain size of the jadeite material is less than about 30 microns and is an equiaxed grain structure. The jadeite material has an optical transmission peak between 500 and 565 nm with an I/IO optical transmission ratio of over 40%. The first step in making the jadeite material is to wrap a glass block, convertible by HP/HT into jadeite and having a nominal composition of NaAlSi2O6, with a graphite or refractive metal sheet. The wrapped glass block is placed in an HP/HT apparatus, rapidly heated, and subjected therein to a pressure in excess of about 3 GPa and a temperature in excess of about 1000° C. for a time adequate to convert the glass block into jadeite. The jadeite material then is cooled and the pressure subsequently released.

  • Publication number: 20020149716
    Abstract: Picture display device having a display panel with an active part on which pictures are displayed, an LC shutter of a size corresponding to the size of the active part of the display panel being arranged in front of the display panel, electrode means being provided for energizing the LC shutter, wherein the energizing being effected in accordance with the on/off operation of the display device, the LC shutter includes an LC cell, the LC cell comprises an LC-gel which can be switched between a light-transmissive state and an opaque, particularly scattering, state, and the LC shutter is fixed to the surface of the display panel by means of an adhesive. The LC shutter becomes transparent in the case of electric breakdown.
