The process includes reversing a direction of gas flow in the reactors after periods of about 1-40 minutes. The temperature in layers of the oxidation catalyst in the reactors is maintained in a range of 300-500 DGE C. The temperature of the gas stream leaving the reactors is at least 50 DEG C below the H2SO4 dew point of the process gas after oxidation of the sulphur content in the feed gas. Condensed sulphuric acid is drained off from the bottom of each of the reactors.

Title: Shield or ring surrounding semiconductor workpiece in plasma chamber
Inventor: KE KUANG-HAN
IPC: H01L21/302
Filed: 1998-09-01
Granted: 2000-08-11
Abstract: A ring or collar surrounding a semiconductor workpiece in a plasma chamber. According to one aspect, the ring has an elevated collar portion having an inner surface oriented at an obtuse angle to the plane of the workpiece, this angle preferably being 135 DEG C. This angular orientation causes ions bombarding the inner surface of the elevated collar to scatter in a direction more parallel to the plane of the workpiece, thereby reducing erosion of any dielectric shield at the perimeter of the workpiece, and ameliorating spatial non-uniformity in the plasma process due to any excess ion density near such perimeter. In a second aspect, the workpiece is surrounded by a dielectric shield, and the shield is covered by a non-dielectric ring which protects the dielectric shield from reaction with, or erosion by, the process gases. In a third aspect, the dielectric shield is thin enough to couple substantial power from the cathode to the plasma, thereby improving spatial uniformity of the plasma process near the perimeter of the workpiece. In a forth aspect, azimuthal non-uniformities in process performance can be ameliorated by corresponding azimuthal variations in the dimensions of the elevated collar and/or the dielectric shield surrounding the workpiece.

Title: A method for immobilizing biocatalyst using gluten
Inventor: LI WEN-CHIAN
IPC: C12N11/00
Filed: 1998-12-03
Granted: 2002-01-21
Abstract: A simple method for preparing immobilized biocatalysts by entrapment of cells, parts of cells, or enzymes within gluten matrix is invented. Gluten is advantageous for use as the entrapping material because it is cheap, biodegradable and harmless to the environment. Powders of gluten are dissolved in NaOH aqueous solution and the resultant gluten solution is added with HCI aqueous solution in order to adjust its pH value. As the pH decreases to a lower value, colloids of gluten are precipitated and the crosslinker and biocatalyst are added and mixed thoroughly. Finally, the pH is adjusted to a much lower value, at which the gel is forming. After casting and drying at low temperature, a preparation of immobilized biocatalyst in the form of sheet (membrane) or granules is obtained. Glutaraldehyde, oxidized starch or other bifunctional reagent can be used as the crosslinker. The biocatalyst to be entrapped can be cell, part of cell, enzyme or a combination of these three. A stainless steel mesh can be placed within the sheet (membrane) of the immobilized biocatalyst as the supporting material. This method can be applied for formulating biopesticides and bio-control agents.

Title: Ferroelectric flat panel displays
Inventor: KANO GOTA
IPC: G09F9/30
Filed: 1999-06-08
Granted: 2001-04-01
Abstract: A thin film of ferroelectric layered superlattice material in a flat panel display device is energized to selectively influence the display image. In one embodiment, a voltage pulse causes the layered superlattice material to emit electrons that impinge upon a phosphor, causing the phosphor to emit light. In another embodiment, an electric potential creates a remanent polarization in the layered superlattice material, which exerts an electric field in liquid crystal layer, thereby influencing the transmissivity of light through the liquid crystal. The layered superlattice material is a metal oxide formed using an inventive liquid precursor containing an alkoxycarboxylate. The thin film thickness is preferably in the range 50-140 nm, so that polarizability and transparency of the thin film is enhanced. A display element may comprise a varistor device to prevent cross-talk between pixels and to enable sudden polarization switching. A functional gradient in the ferroelectric thin film enhances electron emission. Two ferroelectric elements, one on either side of the phosphor may be used to enhance luminesence. A phosphor can be sandwiched between a dielectric and a ferroelectric to enhance emission.

Title: Method and apparatus for dynamically adapting a connection state in mobile communications system
Inventor: BARK GUNNAR
IPC: H04L12/56
Filed: 1999-06-17
Granted: 2001-03-01
Abstract: In a mobile communications system that provides packet data services, a packer data connection is established between a mobile station and a radio access network. The state of the connection is used to specify one of plural different types of radio channels bearing the connection over the radio interface. The connection state preferably also may specify other parameters including, for example, one of plural different mobility management schemes tailored to the selected channel type or channel bit rate(s). The connection is dynamically adapted to an optimal state based on one or more conditions relating to the connection. For example, one or more traffic parameters are determined for the connection and may be used to predict a future value of that parameter. Based on the predicted parameter value or values, an optimal connection state is determined and implemented. If the predicted parameter value changes later in the connection, another connection state may be dynamically selected that is better suited in accordance with the newly predicted parameter value. One example embodiment is based on the amount of data in queue for a packet data connection. Comparison is made with one or more thresholds to decide which type of radio channel should bear the connection. Other factors, parameters, and conditions may be employed along with threshold comparisons to select the optimal radio channel type.

Granted: 2001-11-21
Abstract: The present invention seeks to overcome the above-identified deficiencies in the art by providing a built-in printed spiral antenna which is small enough to satisfy the needs of future compact mobile terminals. According to exemplary embodiments, a built-in antenna is provided which includes a printed spiral metal strip that is connected to the mobile terminal's printed circuit board via a substrate. Matching of the antenna is performed by a matching bridge which is positioned between a feeding pin and a grounded post. By adjusting the length of the matching bridge, the matching of the antenna can be changed. In an alternative embodiment, a loading resistor is attached to the matching bridge in order to enhance the bandwidth of the antenna. The size of the antenna of the present invention can be reduced to 20-30% of the conventional PIFA antenna (i.e., less than 1/10 of the wavelength of the operating frequency). As a result, the antenna can be used in a very compact chassis.
