Abstract: A multi-layer LC resonance balun includes at least a section of broadside coupled lines connected to an input port and two balanced output ports through transmission lines. Each section of coupled lines has two coupled lines. The first embodiment has at least two sections of coupled lines connected to a transmission line and coupled in parallel with at least one capacitor. The coupled lines are connected to an input port and two balanced output ports. The second embodiment has at least a section of coupled lines coupled in parallel with capacitors and then connected to an input port and two balanced output ports through transmission lines. By means of a multiple layer dielectric structure and meandered coupled lines, the size of the blaun is decreased and the frequency bandwidth is increased.

Abstract: A plurality of ceramic substrates are used to manufacture and integrate a highly integrated multi-layer circuit module. Integrated circuit devices are mounted on one or both surfaces of the circuit module whose multi-layer structure is divided into three types of integration regions including inter-connection integration regions, basic passive device integration regions and high frequency passive device integration regions. Connection layers are formed in the inter-connection integration regions for connecting integrated circuits. Basic passive device integration regions include capacitor, resistor and inductor layers. Filters, couplers and baluns are fabricated in the high frequency passive device integration regions. Shielding ground planes are provided for the isolation of devices to prevent electromagnetic interference. Standard input and output contacts are formed on the bottom surface so that the circuit module can be used as a modularized device.

Abstract: A computer enclosure for enclosing electrical devices comprises a chassis having a bottom panel and a pair of side panels with a reduced height portion adjacent to a rear panel. The rear panel includes a wing fixedly attached to the reduced height portion and is coplanar to the side panel. The reduced height portion defines a recess. A spring latch extends downward and outward from the wing portion of the rear panel. A cover is detachably assembled to the chassis having a top panel and a pair of side panels corresponding to the side panels of the chassis. The cover includes a latch plate received in the recessed portion of the reduced height portion and engaged with the spring latch and a hook is interlocked to a planar portion of the reduced height portion when the cover is assembled to the chassis.

Abstract: Two novel diacylglycerol kinase (DGK) isoforms are disclosed. The cDNA of one DGK isoform, designated DGK&egr;, is about 2.6 kb in length. The DGK&egr; cDNA has an open reading frame encoding 567 amino acids and has a predicted molecular mass of 63 kDA. DAG kinase &egr; is highly selective for arachidonate-containing diacylglycerol (DAG) substrates. The cDNA of the second isoform, designated DGK &zgr;, is 3.5 kb in length. The DGK&zgr; cDNA contains a single large open reading frame encoding a 928-amino acid protein with a predicted molecular mass of 103.9 kDa. An alternatively spliced muscle specific species of DGK&zgr;, DGK&zgr;-2 is also disclosed and characterized. DGK&zgr; is localized to the nucleus. A lysine-rich region with homology to the MARCKS protein is shown to be necessary and sufficient to confer nuclear localization to DGK&zgr; via a protein kinase C phosphorylation.

Abstract: A state machine with a dynamic clock gating function according to the invention is disclosed. In the state machine, a gating clock control logic is used to gate a clock signal input to flip-flops which do not need a clock sample input. Accordingly, the total capacitance of capacitors which are charged/discharged following the state transition of a clock signal is greatly reduced, thereby decreasing the power consumption of the state machine.

Abstract: A method of removing spinning and finishing oils from fibers using supercritical carbon dioxide as an extraction media is provided. This process using carbon dioxide to remove oils from fiber surface operates at moderate pressures between 90 and 350 bar and at temperature levels ranghng from 40 to 120° C. The treated fibers have improved strength and elongation properties compared to those treated by conventional scouring. The treated fibers can be directly subjected to the subsequent dyeing processing.

Abstract: Two novel diacylglycerol kinase (DGK) isoforms are disclosed. The cDNA of one DGK isoform, designated DGK.epsilon., is about 2.6 kb in length. The DGK.epsilon. cDNA has an open reading frame encoding 567 amino acids and has a predicted molecular mass of 63 kDA. DAG kinase .epsilon. is highly selective for arachidonate-containing diacylglycerol (DAG) substrates. The cDNA of the second isoform, designated DGK .zeta., is 3.5 kb in length. The DGK.zeta. cDNA contains a single large open reading frame encoding a 928-amino acid protein with a predicted molecular mass of 103.9 kDa. An alternatively spliced muscle specific species of DGK .zeta., DGK.zeta.-2 is also disclosed and characterized. DGK.zeta. is localized to the nucleus. A lysine-rich region with homology to the MARCKS protein is shown to be necessary and sufficient to confer nuclear localization to DGK.zeta. via a protein kinase C phosphorylation.

Abstract: A flying dish having a convex center portion surrounded by a concave ring portion. The convex center portion has the form of the pistils of a flower. The concave ring portion supports petals of a flower. The concave ring portion contains respective pivot axles for the flower petals. Each pivot axle is provided with a coiled spring extending between the inner wall of the concave ring portion and a slot on the back of a flower petal. Each flower petal is provided with a small whistle. When the rotational speed of the flying dish reaches a predetermined level, the flower petals open under centrifugal force and begin whistling due to the air stream. When the speed of the flying dish slows, the flower petals gradually close and the whistling disappears.
