Patent DE-4408452-A1 (DE)
Inventor: FORSTER BRIAN PAUL
IPC: G05D7/01
Filed: 1994-03-12
Abstract: A flow controller 2 comprises an input 4, a first flow line and a second flow line in parallel. The first flow line includes a valve 12 and a governor 16 in series. The second flow line includes a valve 14. Each flow line may comprise two valves.

IPC: H01L21/336
Filed: 1994-03-17
Abstract: A thin-film transistor according to the invention contains a gate (45) made in the form of a wedge and has a reduced switch-off current. In order to produce it, a semiconductor layer (43) is first applied onto a substrate (41) having an overlying insulation layer (42), on which semiconductor layer there is a gate-insulation film (44) having an overlying gate (45). The gate (45) has an upper extent which differs from its lower extent. The gate-insulation layer (44) is formed more thickly in both lower side regions of the gate (45) than in the middle or directly below the gate (45), so that its surface is concave. A first impurity region is located in the semiconductor layer (43) on one side of the gate (45), whereas a second impurity region is located, within the semiconductor layer (43), on the other side of the gate (45) and at a distance from the first impurity region.

Title: Piezometer/permeameter probe
Inventor: PUNZEL JUERGEN DIPL PHYS DR RE
IPC: G01N15/08
Filed: 1994-09-23
Abstract: The hydraulic conductivity as a function of the suction pressure can be determined in a series of steady-state, radially symmetric infiltration flows from a spherical source surface. For this flow shape, the Darcy equation can be solved exactly independently of the type of conductivity function. In practical application of this method, a tensiometer has to date simultaneously been used as the infiltration source as well. The high flow resistance of the tensiometer restricts the method to pressure ranges of above 200 hPa. Very long measuring times at very low infiltration rates prevent the use of this method for a surveying instrument. An infiltration source and a tensiometer are combined to form a piezometer/permeameter probe. The infiltration source has a very small flow resistance and allows constant infiltration rates to be set up to saturation of the adjacent ground volume. A tensiometer on the probe axis below the infiltration source exactly indicates the soil pressure on the effective source surface. At a predetermined infiltration rate, steady-state flow conditions are indicated by a constant limit value of this pressure. Piezometer/permeameter probe for determining the hydraulic conductivity in the near-saturated range.

Abstract: A program reservation system, i.e. a VTR control (16) is set into a preset mode by a remote control (26) or a key (28). In the preset mode, a broadcasting signal of a television channel set by a channel selecting circuit (18) is received by a tuner (14), and a VPS signal contained in the broadcasting signal is derived by a VPS signal deriving circuit (24). A station code contained in the VPS signal is compared with station codes stored in advance in a station code area (34b) of a memory (34). If there is a coincident station code, television channel data is written into a storage position of a channel area (34a) of the memory corresponding to a storage position of the station code. On the other hand, since data of inherent numbers inherently assigned to respective broadcasting stations are written in advance in an inherent number area (34c) of the memory (34) in corresponding to the station codes, a table in which the inherent number data and the television channel data are written in corresponding to each other is formed in the memory (34). <IMAGE>
