Title: Microwave field effect device
Inventor: EISENBERG JOHN A
IPC: H03K17/687
Filed: 1989-12-08
Abstract: Abstract of the Disclosure A monolithic microwave integrated circuit switch includes a series field effect transistor having a source drain path in series with an inductive transmission line including plural taps. Source drain paths of plural shunt field effect transistors are connected to the taps. The source drain paths of the series and shunt transistors are biased so that the series and shunt source drain paths have complementary low and high impedance states. The high impedance state is capacitive, having a value on the order of magnitude of the inductive transmission line. During a first time interval, the capacitive and inductive impedances form a matched low pass filter to supply current from a microwave source to a load. During a second time interval, current from the microwave source flows through the shunt field effect transistors to be decoupled from the load. The circuit is in stripline form, with source electrodes of field effect transistors including first and second arms respectively having first and second elongated parallel sides. First and second elongated edges of drain electrodes of the transistors extend parallel to the elongated sides. A gate electrode of each transistor includes first and second elongated fingers respectively extending parallel the elongated sides and edges. The first finger is between the first side and first edge; the second finger is between the second side and second edge.

Inventor: WILSON ROBERT G
IPC: D03D13/00
Filed: 1990-08-03
Abstract: A papermakers' fabric, especially a forming fabric, with very high fiber support and open area on its top surface for superior papermaking characteristics.  The papermaking surface consists of a woven fabric layer with single float machine direction yarn knuckles; i.e., no machine direction yarn passes over two or more adjacent top surface cross machine direction yarns.  To complete the papermaking surface, into this base structure is woven two additional, generally smaller diameter, cross machine direction yarns for every cross machine  direction yarn in the base weave papermaking surface.  These two additional cross  machine direction yarn pairs are woven in reverse weave patterns to one another such that natural interposing forces cause the two yarns to align one over the other centrally between two adjacent cross machine direction yarns of the fabric layer.  One yarn of the interposing pair functions as an additional fiber supporting yarn while the other yarn acts as a locator yarn to position the fiber supporting yarn in the proper or ideal location on the papermaking surface.

Title: Intra-cell call hand-over in radio communication systems with dynamic channel allocation
Inventor: STRAWCZYNSKI LEO
IPC: H04W36/30
Filed: 1990-12-14
Abstract: The intra-cell call hand-over technique of this invention is characterized by the use of channel information from both base station and subscriber terminal in determining a standby radio traffic channel upon which to hand over a call.  Communication between the base station and subscriber terminal is carried out on an inband or associated signalling channel for the selection of the standby traffic channel.  The standby radio channel is the channel, which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal.  The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service.  This subset is comprised of those channels having little interference as measured by the base station. The call hand-over technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal.

Abstract: The toe piece binding (1) has a support bearing (13) which is mounted rotatably in lateral bearing blocks (7), fixed to the ski, and on which the ski boot (14) rests with positive fit in the touring position. To achieve this positive fit, the boot sole has a recess (22) which is matched to the support bearing (14) constructed as a straight shaft, and in which the support bearing fits. Serving for fastening the boot on this support bearing is a tightening lever (9) which is mounted so as to be swivellable by means of tensioning struts (8) and has at its one end a pressure piece (10) which presses onto the projecting edge of the boot sole (11) in its closed position in which the tightening lever is in an after-dead-centre position. For downhill skiing, the boot is placed directly on the ski and the tightening lever (9) is swivelled below the support bearing (13) and has at its end opposite the pressure piece (10) a holding-down device (12) for the sole which grips over the upper sole edge in the downhill skiing position. In order that the tightening lever mounted so as to be swivellable on the tensioning struts cannot escape upwards, it is held by the support bearing (13), below which it is swivelled for the downhill skiing position.
