IPC: H01L29/10

Abstract: The cathode-side base region of the thyristor is subdivided into a central region (7) and an edge region (5) bevelled at a small angle. The central region has a higher edge dopant concentration and, on the cathode-side surface, a higher doping gradient than the edge region. It is thus possible to, on the one hand, highly dope the cathode-side base region (4) centrally and, on the other hand, dimension it at the edge so as to achieve a sufficient reverse voltage. Any running of the space-charge region into the central region is prevented at the surface (11) by ensuring that the overall dopant concentration in the edge region within the space-charge region is greater than 1 ô 10<12> atoms cm<-2>. <IMAGE>

Abstract: A film densitometer for generating digital density values as a function of analog transmittance signals received at an input. A comparator coupled to the input compares the transmittance signals to one or more range references characterizing a plurality of ranges of transmittance signal magnitudes, and provides digital transmittance range signals as a function of the comparison. An amplifier amplifies the transmittance signals to provide amplified transmittance base signals. A gain control circuit coupled to the amplifier and the comparator controls the gain factor of the amplifier as a function of the magnitudes of the transmittance signals. The amplified transmittance base signals are converted to digital transmittance base values by an analog-to-digital converter. A lookup table of data characterizing the logarithmic relationship between transmittance base values and density base values is stored in base memory. A lookup table of data characterizing the relationship between the transmittance range signals and range gain values is stored in range memory. A digital processor accesses the memory as a function of the transmittance base values and transmittance range signals, and generates the digital density values as a function of a sum of the density base values and range gain values.

Abstract: This invention relates to a heat-insulating engine with swirl chambers which reduces a throttle loss due to the communication ports and increases the speed of a vortex flow within swirl chambers (2). The heat-insulating engine with swirl chambers comprises small communication ports (8) each with a small passage area and large communication ports (9) each with a large passage area formed at the lower portions of the swirl chamber blocks (3) constituting heat-insulating swirl chambers (2), and control valves (11) provided to large communication ports (9). During the compression stroke, the control valves close the large communication ports, and open the same ports during the expansion stroke after fuel injection and on rise in pressure in the swirl chambers (2). Accordingly, during the compression stroke, air is sent into the swirl chambers (2) at high speed via small communication ports (8) to increase a vortex flow speed within the swirl chambers (2). During the expansion stroke, the large communication ports being open, combustion gas and flame are forced into the main combustion chambers (1) from the swirl chambers (2) to reduce a throttle loss.

Abstract: A wireless telephone system capable of servicing a roaming wireless telephone user includes a satellite communications system consisting of at least one orbiting satellite; at least one terrestrial-based gateway having access to a database of users, destination codes (telephone numbers); a network coordinating gateway within a satellite service area; a network control center; and a plurality of terrestrial communications links. The system operates by effecting communication between a terrestrial wireless telephone end user transceiver apparatus and a terrestrial communications link via a single relay through a single satellite or a succession of single relay satellites wherein the relay station may be in motion relative to the end user transceiver apparatus and the terrestrial communications link. The ground-based gateway effects the ultimate decision on linking in cooperation with the network database to effect hand-off from a first orbiting satellite to a second orbiting satellite. The single satellite or preferably a constellation of satellites orbiting near the earth need only translate signals from the gateways to the users and from the users to the gateways without satellite-based control. The gateways are capable of decoding the calls, switching, processing call requests from the end users, processing call requests to the end users, processing call set-ups, handing off of calls to other satellites, and updating databases of users based on information provided by network control and requests from end users.
