When supplying a power from a base station to a terminal station on radio and a distance from a base station to a terminal station is long, it becomes impossible for the terminal station to rectify the power. The feature of the present invention is found in a wireless communication system in which the peak value and duty ratio of a transmission power are controlled simultaneously, keeping the transmission power of a base station below a fixed value, thereby allowing a voltage to be applied to a diode, which is a component of a rectifier circuit possessed by a terminal station, always in excess of a threshold voltage of the diode, and energy is exchanged between the base station and the terminal station below a limit power.

A detonator with a base portion including opposing electrical leads; an exploding foil initiator on the base portion, the exploding foil initiator including two conductive lands separated by a bridge portion therebetween; and a connecting barrel of a predetermined thickness on the exploding foil initiator for optimizing the spacing between the exploding foil initiator and an explosive charge and for robustly interconnecting the lands of the exploding foil initiator with the electrical leads of the base portion.

Ethanol and other liquid products produced by contacting carbon monoxide (CO) and / or a mixture of CO2 (carbon dioxide) and H2 (hydrogen) with a microorganism in a bioreactor are separated using a combination of distillation and vapor permeation membranes. The bioreactor passes an effluent with an ethanol concentration of 1 to 6 wt % to a distillation column that produces an overhead vapor stream enriched in ethanol. A series of vapor permeation membranes retain ethanol as retentate and produce a 99 wt % or higher ethanol product. Ethanol depleted permeate streams flow back to the column and the bioreactor. Coupling a bioreactor with distillation and pervaporation efficiently and economically separates ethanol when present at low concentration in an aqueous fermentation broth. The separation arrangement may also include a flash zone ahead of the distillation column to raise the concentration of the ethanol in the input stream to the distillation column.

The invention relates to a spindle motor having a fluid dynamic bearing system comprising axial and radial bearings that contains a rotor component (14) which encloses a stationary shaft (12), which in turn is connected at both its ends to axially aligned bearing parts (16; 18) that are fashioned such that they form capillary sealing gaps (32; 34), a recirculation channel (28) filled with bearing fluid that connects the remote regions of the bearing to each other, and an electromagnetic drive system (42, 44) for driving the rotor component.

A sliding roof system includes at least one guide rail, a carriage shiftable in the guide rail, and a cover support coupled with the carriage. The cover support is adapted to be attached to a cover that is movable to open and close a roof opening. A first lifting lever has one end connected to the cover support and another end connected to the carriage with guide pieces received within slots formed in the carriage.

A body adapted for relative movement with respect to a fluid, said movement creating a flow of fluid with respect to the body in a relative flow direction, said body having at least one surface with a surface profile exposed to the fluid and comprising at least one smooth step facing in relative flow direction towards the flow, said step having a height between 4% and 30% of the local boundary layer thickness (δ99) of the fluid contacting the body in the vicinity of the step.

ABSTRACTA transceiver (20) for a millimeter wave signal, consisting of a PCB (140) having PCB microstrip lines (141) and PCB waveguide apertures (159), and one or more transmitter modules (22) and one or more receiver modules (24, 26, 28) mounted on the PCB. Each module has a single microstrip-waveguide transition (34, 48) and a microstrip-microstrip transition (47, 49). The microstrip-waveguide transition of each module couples to one of the PCB waveguide apertures via a PCB-module waveguide-waveguide transition (167). The microstrip-microstrip transition of each module couples to one of the PCB microstrip lines via a PCB-module microstrip-microstrip transition (165). The PCB-module transitions are low tolerance, facilitating implementation of the transceiver.
