Abstract: A compactor includes test data inputs that are connectable to circuit outputs of an electrical circuit, test comparison inputs, and test data outputs. The compactor further includes a number of H matrix XOR gates arranged as a switching mechanism between the test data inputs and the test data outputs such that data applied to the test data inputs is produced at the test data outputs compressed in accordance with coefficients of an H matrix of an error-correcting code, and compensation XOR gates arranged between the test data inputs and the test data outputs, each compensation XOR gate including an input for receiving a compensation value.

Abstract: The invention relates to a fuel injection apparatus for an internal combustion engine, having an injection valve that protrudes into the combustion chamber of the engine. This valve communicates with a valve chamber in that a control part closes and opens inlet bores for fuel that is at high pressure. The control part is actuatable by means of a hydraulic-mechanical booster. The pump part, valve part and nozzle part of the fuel injection apparatus are disposed in a vertical arrangement, hydraulically in line with on another in terms of the fuel flow.

Abstract: The invention relates to a fuel injection apparatus for an internal combustion engine, having an injection valve (14) that protrudes into the combustion chamber of the engine. This valve communicates with a valve chamber (6.1), in that a control part (6) closes and opens inlet bores (5, 8) for fuel that is at high pressure. The control part (6) is actuatable by means of a hydraulic-mechanical booster (18, 19, 20, 21). The pump part (P), valve part (V) and nozzle part (D) of the fuel injection apparatus (1) are disposed in a vertical arrangement, hydraulically in line with one another in terms of the fuel flow.

Abstract: The fuel injection apparatus has a pump unit (39), which pumps fuel at high pressure into a high-pressure conduit (10) communicating with an injection valve (1), and having a control valve (11), in which a pistonlike valve member (14) is guided with a sealing portion (114) in the bore (26), the sealing portion (114) being surrounded by a high-pressure chamber (16) that communicates with the pump work chamber (48). With one end, the valve member (14) protrudes one low-pressure chamber (18), which communicates with a fuel delivery system (58). A valve seat (22) is embodied in the bore (26) and cooperates with a valve sealing face (24), embodied on the valve member (14), to control the communication between the high-pressure chamber (16) and the low-pressure chamber (18).

Abstract: A method is proposed for determining parameters for the auxiliary control of the position guidance variable of an axis of a numerically controlled machine path. If the auxiliary control parameters up to the n.sup.th order are known for the i-th axis, auxiliary control parameter of the order of n+1 can be determined by predetermining a guidance variable signal in the form of a parabola of the order of n+1 for the axis. By including the amplification (K) of the control unit (11) and the n+1-th derivation of the guidance variable signal over time, a auxiliary control parameter of the order of n+1 can be determined from the steady-state error which occurs.

Abstract: A method for constructing a superconducting magnet winding which contains parallel winding layers each spaced by a separator and around the outer surface of which hardenable material is cast which is worked to a predetermined dimension after hardening, in which each winding layer is prefabricated individually and its outer surface is provided with a cast, ridge-like extension of hardenable material, and in which all cast extensions are worked down to the fit dimension after the winding is assembled, avoiding cementing of cooling ducts together in the separators.
