Title: Static induction and lateral transistor chip - has high concn. impurity zones for main electrodes of transistors
Inventor: KOJIMA MASAYUKI
IPC: H01L27/02
Filed: 1980-04-08
Abstract: The product of delay and output is decreased by higher gain of common base current of the lateral pnp transistor. The enhanced alpha gain ensures rise of emitter current of the lateral pnp transistor. The substrate features the vertical static induction transistor and the bipolar transistor in the epitaxial layer. The first epitaxial layer (23) is formed by thermal diffusion or ion implantation. The reduced thickness of the epitaxial layer between the base and collector decreases the saturation voltage of the pnp transistor and allows the chip to be used in armband watches. Junction (13) is formed by substrate (I) and epitaxial layer (2) bounding the p-type conductivity zone (3) and depletion layer (7). The gate (3), emitter (5) and base (6) of the pnp transistor are formed using the same mask.

Title: Hot-runner injection moulding device with fixed needle
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/30
Filed: 1981-04-24
Abstract: In a hot-runner injection moulding device with a fixed needle, an injection part with an injection nozzle is separated from the mould plate by an insulating air gap; a nozzle seal with an internal bore extends through the air gap around the injection opening. A hot-runner extends from a hot-runner block through the injection part at an angle and into the nozzle seal. The heat-conducting, fixed needle is centred in the injection part in alignment with the nozzle seal and with the injection opening and projects directly upstream from the injection opening, at an acute angle, from the injection part into the hot-runner in a position in which the tapered end runs in the nozzle seal towards the injection opening. The size of the tapered end and the axial position of the needle are chosen such that the ratio of the surface area of the injection opening to the smallest area of the annulus between the inner wall of the nozzle seal and the outer surface of the tapered end of the needle, through which the melt flows, is 2:1 to 1:2. The heat supply to the hot-runner takes place principally from the exterior, from the injection part, however also from the injection part, via the fixed needle, as far as the tapered end thereof, by means of which additional heat is supplied in the region of the injection opening and the melt is held at a more uniform temperature with the reduction of streaking. <IMAGE>

Title: Test device for an electrical pasture fence device
Inventor: BUESCHEN WALTER
IPC: G01R31/50
Filed: 1981-07-02
Abstract: The invention particularly relates to a battery-operated pasture fence device. According to the invention, the test device is characterised by a circuit, working into the check indicator, comprising a thyristor which switches on the check indicator, which exhibits its own circuit for supplying it, in dependence on a voltage tapped off from the fence voltage generated by the pasture fence device. This measure has the advantage that an incandescent lamp, which is supplied from its own circuit, can be used as check indicator. The test device according to the invention provides particular advantages when combined with a so-called "artificial fence" formed from a capacitor and parallel-connected resistor. As a result, the test device can be applied in many ways. For example, it is possible to carry out checks whether the device produces a required power, and the fence installation itself can also be checked.

Title: Flue gas desulphurisation
Inventor: REMSTEDT HANS GOTTHARD DR DIPL
IPC: B01D53/50
Filed: 1981-07-21
Abstract: This process enables any low-dust flue gas to be scrubbed sulphur-dioxide-free with a high degree of efficiency and flue gas heat originally necessary for SO2 dispersion to be extracted in a utilisable manner and to be used. The residual heat portion still necessary for the energetics of the process is characterised by the temperature difference of 15 DEG  K above the temperature of the purified exhaust gas. Crystalline and thus marketable ammonium sulphate is generated in this case. The high degree of efficiency with simultaneous low heat requirement is made possible by a circulation process in which scrubbing is carried out by ammonium sulphite solution at low temperature, the oxidation to give ammonium sulphate is carried out at a higher temperature in the same tower without steam generation and recooling and the further supply of ammonia, ammonium sulphate precipitation and separating off ammonium sulphate takes place in a single, fully integrated material-loss free and heat-loss free cyclic process. The process has the advantage of high availability, high efficiency, low operating and capital costs and owing to the utilisation of thermal energy and ammonium sulphate fertiliser, it comes into the area of a profit-making industrial method.

Title: Admission pressure valve for hydraulic vehicle brake systems
Inventor: BAUM HEINZ WILLI
IPC: F16D65/72
Filed: 1981-10-30
Abstract: The valve owes its suitability for the vacuum venting of a hydraulic brake system to the installation of a component (7), responding to pressure, which responds to a vacuum in order to open the valve automatically at the commencement of vacuum venting, following which air can be freely drained off. The component responding to pressure may be a differential piston (7), which functions in a bore (2) in a housing (1). A finger (17) limits a movement performed by a second valve body (12) together with the differential piston (7) when the latter is drawn out of the bore (2) owing to a vacuum acting on its end with a larger surface area, as a result of which a valve seat (13) on a first valve body (9) is moved away from the second valve body (12). In another embodiment, the finger (17) may be adjustable together with a piston or with a diaphragm, in order to raise the valve body (12) from the valve seat (13). <IMAGE>
