Title: In situ polymerization of conducting poly(3,4-ethylenedioxythiophene)
Inventor: FREUND MICHAEL S
IPC: C08F134/04
Filed: 2010-07-09
Abstract: Conducting poly(3,4-ethylenedioxythiophene) films are prepared upon solvent removal using an easily processable metastable solution of monomer and oxidant. This method allows the casting and spin-coating of films on conducting as well as insulating substrates with conductivities as well as optical and redox properties similar to those reported for chemically (vapor phase) and electrochemically synthesized thin films. Morphological characterization of spin coated poly(3,4-ethylenedioxythiophene) films suggest that they are smooth, uniform and free of pinholes on the micron scale. These films show conductivities in the range of 0.03 to 5 S/cm.

Title: Article conveying system and analyte processing system
Inventor: ONIZAWA KUNIAKI
IPC: G01N35/02
Filed: 2010-07-20
Abstract: An object of the present invention is to provide a sample processing system, wherein writing to each RFID is equalized to eliminate unevenness in the use of sample containers.  The configuration of the present invention can be realized by controlling the numbers of times (write counts) data is written to RFIDs, and by skipping data writing according to frequencies in the use of sample containers.  Setting use information (count) of each IC tag, and comparing the use information with an average value of the use of the IC tags, make it possible to limit the write counts, which enables the equalization of writing to the IC tags, thereby making it possible to uniform the use of the sample containers in the system.

Title: Disc brake assembly containing split discs.
Inventor: ENRIGHT JOHN JOSEPH
IPC: F16D65/00
Filed: 1980-04-22
Abstract: A split disc for a brake (10) or clutch in which split discs (37, 38) are positioned for frictional engagement with full width discs (42, 43, 44). Noise reduction is provided by damping through contact friction between the split disc members (45, 46) of the split discs (37, 38).

Title: Resolution improvement in an ion cyclotron resonance mass spectrometer
IPC: H01J49/38
Filed: 1989-06-06
Abstract: In an ion cyclotron resonance mass spectrometer (10), ion cyclotron resonance signals at higher harmonics of cyclotron frequency are employed to increase the resolution of ICR mass spectrometer without increasing the magnetic field. The detection electrodes consist of M (where M is an integer) identical electrodes (A, B, C, D) arranged in M-fold symmetry about the axis of the coherent cyclotron motion of the observed ions. In an ion cyclotron having four points of voltage in space, the cyclotron electrodes are set up in clockwise symmetric fashion. To increase the resolution in signal detection resulting from the potential induced by ions moving in orbits in the spectrometer, the first and third voltages are added and the second and fourth voltages are subtracted from the sum of the first and third voltages.
