Abstract: The planar semiconductor device comprises a monocrystalline semiconductor wafer (10) of a first conduction type, a first area (11) of an opposite conduction type, and diffused in the wafer (10) from the main upper surface and forming with the material of the semiconductor wafer (10) a pn junction (12), and a passivation layer (13) covering said main upper surface of the wafer (10) except for contact windows. A second area (14) having an annular shape, acting as a stop ring and being of the same conduction type as the base material of the wafer (10) but with a higher concentration of impurities, is diffused in the semiconductor wafer (10), from said main upper surface, all around the first area (11). On the passivation layer (13) there is arranged a metal layer used as a covering electrode (15) which surrounds annularly the pn junction (12) and covers the intersection line of said junction with the main upper surface of the semiconductor wafer (10). Said metal layer extends up to an area located above the annular area (14). Thepotential of the covering electrode (15) may be adjusted so as to be located between the potential of the first area (11) and the potential of a portion of the wafer (10), located outside of said first area (11) and having a conduction type opposite to that of the first area (11). For adjusting the potential of the covering electrode (15), there is provided a voltage divider (16).

Abstract: Microbial polysaccharides can be quantitatively precipitated from their aqueous solutions, in particular directly from the fermentation solutions, in an acidic medium in the form of an adduct with a tertiary amine which has a long-chain alkyl radical. It is advantageous to add the amine to the polysaccharide solution and then to carry out the precipitation, in particular by adding the dispersion obtained to an acidic coagulation bath. The adducts are suitable for use as thickeners and for preparing the free polysaccharides.

Abstract: A rolling stand including a pair of working rolls and associated backing rolls, the working rolls defining a nip through which a strip can be advanced in a succession of passes forming a single run, so that with each pass the thickness and widths of the strip are reduced. The working rolls have end regions projecting laterally beyond the longitudinal edges of the strip, and machining devices are provided on the frame of the stand to reduce the diameters of the projecting end regions of the working rolls after each pass during a single run so that the working rolls ony contact the respective backing rolls along a distance equal generally to the strip width. Each machining devices includes a support carrying a material-removing tool engageable with the juxtaposed end region of a respective run of the working rolls, each support being pivotable about the respective backing-roll axis and linearly displaceable along the respective working-roll end region to enable the respective tool to be moved both perpendicularly and parallel to the axis of the working roll. Respective stop elements pivotable about pivot axes parallel to the working-roll axes carry eccentric stops which are engageable with the tool supports to define the radially innermost end positions of the supports.

Abstract: A syringe for collecting a sample of blood or another liquid comprises a syringe cylinder and a piston arranged displaceably therein. One or more axially extending recesses are formed in the inner wall of the syringe cylinder axially spaced from the inner end thereof. The recess or recesses contain a material which is pervious to gas and impervious to liquid, such as a hydrophobic material, a hydrophilic material with capillary effect, or a material which swells when contacted by liquid. The sample collecting chamber within the cylinder may be vented to the atmosphere by placing the piston in the recessed area of the cylinder. Arterial blood may then pass into the syringe under arterial blood pressure, and the flow of blood into the syringe is automatically stopped when the sample collecting chamber of the syringe has been filled, because blood cannot pass the liquid impervious material arranged in the recesses. The axial innermost portion of the inner cylinder wall, which is not recessed, may cooperate with the piston in a conventional manner so as to provide a suction effect within the blood collecting chamber, if desired.

Abstract: A process for producing a casting mould with chemically bound moulding material using a pattern is intended to make it possible to forego the use of clay-bound sand, in particular for the mass production of cast members, and to provide a casting mould of adequate gas permeability, which is simple to produce, with a low level of consumption of moulding material, and inexpensive, and which also provides a high level of casting quality wth a low degree of environmental pollution. For that purpose, the moulding material which has become pourable or fluid due to the operation of casting a cast member is removed from a first casting mould comprising a single moulding material, whereas the remaining portion of the moulding material is left, and the hollow space formed when the pattern is re-fitted is filled with moulding material. In addition, the moulding material which has been reduced in strength may be also removed, being for example blown or brushed out.

Abstract: Circular heading machines for excavating tunnels by advancing a machine in step-wise fashion and erecting tunnel supports. The circular heading machine has an elongate machine body (10) at the forward end of which a forwardly directed cutter boom (11) is mounted, rams advance the machine body in step-wise fashion acting against grippers (23) and a profile ring (18, 18') limits peripheral movement of the cutter boom to form an accurate profile. A gathering apron (16) is provided at the forward extremity of the machine body. The cutter boom (10) is mounted on a sliding carriage (12) longitudinally movable on and independently of the machine body and a hood (17) overlies the apron. A cage structure (21) extends rearwardly from the hood structure and surrounds the boom cutter (11) and sliding carriage (12) and tunnel support erecting means (20) are provided externally of the cage structure, directly behind the hood structure. Thus the tunnel support structures are erected over the machine body rather than behind the machine, and also erection of the tunnel support structures takes place simultaneously with operation of the cutter. The hood (17) is a semi-circular member supported by hydraulic rams (17A) for height adjustment.

Filed: 1986-07-02
Granted: 1989-05-10
Abstract: A small electric device powered by solar cells and by a capacitive charge storage element has stable actuation assured during startup with an as yet uncharged capacitor. Startup problems are avoided by control of the power supply with a threshold value circuit that allows power to be supplied to device components when the components' minimum actuating voltage level has been attained at the capacitor. A deactuating voltage value of the threshold value circuit that is lower than the actuating voltage level prevents interruptions of operation similar to relaxation oscillation behavior due to temporarily increased actuating power requirements by causing deactivation of the components only if the capacitor voltage has dropped below a predetermined operational minimum. In this manner additional functions (such as radio watches with automatic hands setting devices or directional antennas, or ornamental pendulums or alarm or striking watches) which have components with higher acutating power requirements may be supplied without batteries by solar cells without having to overdimension the storage capacitor for the high startup load and thereby unnecessarily delay actuation of the device upon the exposure to radiation of the solar cells.
