Patent EP-0391139-A2 (EP)
Inventor: TISCHER KURT MANFRED
IPC: H01J31/12
Filed: 1990-03-21
Abstract: Cathode wires (K1-K5), which are connected for emission only at times and run in the line direction, are provided in a flat display device. Line electrodes (L1-L10) are assembled into groups, all the line electrodes within one group being driven via a single terminal. The distance between adjacent line electrodes within a group is greater than the height of the region which is covered by electrons from emitting cathode wires. In this way, electrons can be controlled in lines using only a few driving leads. A cathode/line electrode synchronisation circuit (15) is present for synchronising the potentials on the cathode wires and the line electrodes. <IMAGE>

Abstract: When a slip value of the driven wheel (1RL, 1RR) of a vehicle on a road surface reaches a predetermined value, the braking force is applied to the driven (1RL, 1RR) wheel by means of slip control. The slip control by application of the braking force to the driven wheel (1RL, 1RR) is inhibited when the vehicle speed reaches a high speed above a predetermined vehicle speed.

Abstract: The multipurpose automatic injector for automatic injecting one or more different injection substances in liquid or powder aggregation ensures a several years long period of storage of these different and from each other separated substances and, accordingly, it ensures also the required chemical and pharmacolo­gical stability of the same. The injector according to this invention is very simple to be handled as there are only two operation steps required for it to be used, namely: to remove the safety cover (51) and place the tapered tip (15) of the barrel (10) to the administe­ring place and press it by force not exceeding 45 N. All the other operations are carried out by the injec­tor fully automatically so that, after the complete removal of the air from the chamber containing the substance in powder (40), it carries out mixing of the separately stored substances (40) and (42) and unlocking of the automatic discharge mechanism. This is followed by the emanation of the injection needle (22) from the barrel (10) and its entering into the body and at the same time injecting the injection solution. The injector is again ready for use after the discharge mechanism is afresh locked and a new barrel (10) is inserted with all its inner members and substances into the cylindrical body (50).

Abstract: In order to improve the thermal efficiency for the smelting of metals in a melting and casting furnace which can be subjected to oscillating motions, and to improve the purity and homogeneity of the melt, it is proposed to circulate the melt in a multi-chamber furnace by means of the oscillating motions and to control the circulation rate of the melt by means of passage orifices of controllable cross-section. The charging material to be smelted is here introduced into a charging trough (18) and only flooded by the melt for part of the time, so that only small quantities of interfering metallic constituents of the charging material can dissolve in the melt. Since the melt in at least one chamber can flow forward into the neighbouring chamber only below the bath level, the dross arising is automatically collected in this chamber, so that the melt is self-cleaning. As the melting unit for carrying out the process, a furnace is proposed whose furnace space (2) is separated into a preheating chamber (5), a balancing chamber (6) and a discharge chamber (7), the charging material in the preheating chamber (5) being introduced in a raised charging trough (18) which is flooded for only part of the time by the melt due to the oscillating motion. The individual chambers (5, 6, 7) are mutually connected by passage orifices (8, 9, 10, 11) for allowing the melt to pass through and have passages (12, 13) for passing through heating gases and flue gases, resulting in optimised preheating of the charging material in the preheating chamber (5). <IMAGE>

The apparatus measures a distance to the target object based upon the cross-correlation value. 
     Also, a relative position measurement apparatus measures distances to an operator from plural points on the apparatus (9) and then measures a relative position of the operator with respect to the apparatus (9) based upon the plural distances.

Abstract: A multi-layer coating method by which multi-layered magnetic recording media having good recording characteristics can be produced consistently at high speed with multiple thin layers being coated simultaneously while insuring effective prevention of unwanted phenomena such as color unevenness and longitudinal streaks. A plurality of organic solvent based dispersions that are non-Newtonian fluids having fine particles dispersed therein are simultaneously applied in superposition onto a continuously running nonmagnetic support using an extrusion type applicator head. The coating operation is performed in such a manner that the Reynolds number as determined by the average of the viscosity coefficients of the dispersions, the coating speed and the equivalent diameter during coating is adjusted to 400 or below, and that, at the same time, the yield stress of at least the dispersion for the topmost layer is adjusted to 10 dyne/cm² or more. Further, the coating operation is performed in such a way that the ratio of η T  to η H  is adjusted to 50 or above, where η H  is the viscosity of the dispersions at the rate of shear that is exerted upon the dispersions when they are applied using an extrusion type applicator head, and η T  is the viscosity of the dispersions at the shear rate for the time period defined by the end of application and the entrance into the subsequent drying zone.

Abstract: A bridge plug for sealing a well casing (172) comprises a plurality of cups (Δ 1) which tightly interfit together when a compressive load is applied to both opposite ends of the plurality of cups. 
     Application of the compressive load to both opposite ends of the cups ( Δ 1) forces a first cup (1a) to fit into a second cup (1b), the second cup to fit into a third cup (1c), and the third cup to fit into a fourth (1d) cup, etc, thereby producing a single unitary plug which includes a plurality of tightly interfit cups. Further application of the compressive load to both opposite ends causes transverse expansion of the plurality of interfit cups to occur. When the cups contact the well casing wall (172), a permanent seal (178) is achieved between the cups and the well casing wall. Anchor elements (A4) on both sides of the cups contact the well casing wall and permanently hold the interfitting cups in their compressed condition.
