Title: Ion battery using high aspect ratio electrodes
Inventor: NARANG SUBHASH C
IPC: H01M4/36
Filed: 1998-12-16
Abstract: Electrodes (105) for secondary (rechargeable) batteries are fabricated using active material particles (144) such as flakes, fingers, projections, needles, threads, fibers, pods, hairs, ribbons and the like, which have an aspect ratio of at least 1:3:1. The high aspect ratio, in combination with relatively shallow discharge cycles, provides high power of at least 800 W/kg sustainable over at least ten seconds, high energy of at least 7 W-hr/kg to full discharge, and a high cycle life of at least 250 cycles. Selection of parameters also provides power-to-energy ratios for high power, high energy batteries of at least 10. Preferred chemistries for the novel batteries include lithium ion, and preferred active materials include metal oxides and metals. Batteries including the novel technology can advantageoudly be used in electric vehicles, consumer electronics, electrical appliances, and industrial applications such as battery backup systems and switches.

Abstract: The invention relates to an optoelectronic device (1) for detecting objects (2) in a monitoring range, one end of which comprises a transmitter (3) that emits transmitting light rays (8) and two receivers (4, 5) that receive light rays (10) and have respectively one first and second linear polarizing element (14, 15) installed in front, for which the polarization directions are such that they are turned relative to each other by an angle alpha in the range of 45°<alpha<135°, while the other end has a reflector unit (9), comprising a reflector (17) with a third linear polarizing element (16) installed in front, for which the polarization direction essentially coincides with the polarization direction of the first or second polarizing element (14, 15). The receiving signals present at the outputs of the receivers (4, 5) are respectively assigned two different threshold values S1 and S2 (S2>S1), for which the interval is selected such that the receiving signal of a receiver (4) is above S2 and the receiving signal of the second receiver (5) is below S1, but only for a clear optical path. Means for testing the device (1) are provided which, when activated, cause the receiving signals of the receivers (4, 5) to assume predetermined switching states with respect to the threshold values S1 and S2, that is during an error-free operation. Alternatively, the quotient of the receiving signals for receivers 4, 5 can also be assigned a threshold value S.

Abstract: A method of producing a highly pure trimethylolpropane from a crude trimethylolpropane obtained by a reaction of n-butyl aldehyde and formaldehyde in the presence of a basic catalyst in a two-stage process of an aldol condensation and a crossed Cannizzaro reaction. Since a high-boiling component and an inorganic salt are removed in advance from the crude trimethylolpropane, hardly removable impurities such as condensation products in the crude trimethylolpropane are changed in the subsequent heat treatment under acidic conditions to components easily removable by distillation. By distilling the heat-treated crude trimethylolpropane, a highly pure trimethylolpropane with a low content of remaining formaldehyde and a low coloring degree is easily obtained.

Abstract: An waveform equalizer equalizes the signal
reproduced from an optical disc to remove reproduction
waveform distortion with a frequency characteristic
controlled. A binary coder and a PLL circuit generate a
bit clock. An a/d converter a/d-converts the equalized
signal in response to the bit clock. A Viterbi decoder
including metric operation decodes the output of the a/d
converter in response to the bit clock.
The metric operation generates a metric operation
result from an output of the a/d-converter and prediction
data. The Viterbi decoder decodes the output of
the a/d converter through the metric operation according to
prediction data. An operating circuit generates an
equalizing error from the output of a/d converter and a
waveform equalizing target. A coefficient generator
controls the frequency characteristic according to the
equalizing error to minimize the equalizing error. The
prediction data for the metric operation is obtained from
the output of the a/d converter for better decoding.

Alternatively, the PD-Loop can be used to initiate polymerase extension of a primer to thereby facilitate sequencing of the double stranded nucleic acid even in the presence of large excesses of unrelated double stranded nucleic acid. As an additional feature, the PD-Loop can also be used to generate a construct comprised of a double stranded nucleic acid through which is threaded a single stranded closed circular nucleic acid wherein the closed circular nucleic acid can be used in a signal amplification methodology.
