Patent DE-3724094-A1 (DE)
Title: Device for determining the air mass drawn into the cylinders of an internal combustion engine
Inventor: JORDAN WOLFGANG DR
IPC: F02D41/18
Filed: 1987-07-21
Abstract: A device of the said type in connection with an electronic fuel device has the disadvantage that in mobile operation the air mass flow sensor signal is incorrect for determining the injection signal, due to the proportion of air which flows into the intake pipe downstream of the throttle valve. In the case of a new device, it is therefore proposed that in a mobile operating state, detected by way of acceleration detector and decision circuit devices, the air mass is determined from performance characteristics addressed with the signals of an engine speed and intake pressure sensor and the calculation used as basis for the injection signal. Use of the engine in a motor vehicle is thereby possible, optimum power output, economy and low pollutant emissions being achievable.
Patent DE-3724703-A1 (DE)
Inventor: HERNANDEZ JORGE M
IPC: H05K3/34
Filed: 1987-07-25
Abstract: High frequency noise is decoupled from power supplied to a Pin Grid Array (PGA) package by insertion of a decoupling capacitor between the PGA package and printed circuit board. The decoupling capacitor comprises a multilayer capacitive element sandwiched between a pair of conductors and having a plurality of leads extending from each conductor. The decoupling capacitor is individually dimensioned and configured to fit under a PGA package and to correspond to the power and ground pin configuration of that PGA package, and plugs into the same or different holes in the pcb or receives the PGA pins through apertures in the capacitor leads. The conductors make contact with the capacitor electrodes by conductive bias (92) or end terminations, the latter being insulated from the end electrodes by dielectric steps (106). One or several capacitors can be received in a cavity in an insulating block, sandwiched between conductors and produced in a continuous line. <IMAGE>

Patent DE-3726582-A1 (DE)
Title: Method and device for converting input variables, in particular for simultaneous analog/digital conversion
Inventor: LINDEN WILHELM DIPL ING
IPC: H03M1/10
Filed: 1987-08-10
Abstract: Drift-free converters, in particular analog/digital converters, require a very high equipment output if simultaneous conversion of a plurality of input variables requires a high resolution in conjunction with short conversion times. In order to correct the drift dependence of other converters at periodic intervals by calibration measurements without the need to interrupt the conversion during calibration, an additional converter calibrated at periodic intervals is used in addition to the regular converters required for the regular conversion. The additional converter sequentially undertakes the regular conversion of the input variables between two calibrations, with the result that each of the regular converters is temporarily relieved and can be recalibrated. <IMAGE>

Title: Piston/cylinder arrangement
Inventor: KIESEL ECKHARDT
IPC: F15B15/28
Filed: 1988-08-02
Abstract: Piston/cylinder arrangements with a cylinder housing, a piston which is axially displaceable in the bore of the cylinder housing, is sealed off from the cylinder wall and subdivides the bore into two cylinder chambers, and also a displacement transducer fastened to the cylinder housing for measuring the piston travel have the disadvantage that, under the effect of temperature fluctuations, zero-point displacements result in the position control circuit which lead to undesirable control deviations, and that the core of the displacement transducer is only fastened on one side and is therefore subjected to vibrations. This is to be avoided by the novel arrangement. In the piston/cylinder arrangement, a displacement transducer (15, 115) is provided in a centre position and concentrically in the arrangement in order to measure the piston travel. To this end, the centre area of the piston (3, 103) is provided with a continuous slot (14a, 114a) running along and concentrically to the axis. The fastening flange (16, 116) of the displacement transducer (15, 115) fastened to the cylinder housing (1, 101) projects into the slot (14a, 114a). At this location, the displacement transducer (15, 115) carries a coil body (21, 121) likewise in a centre position and concentrically to the longitudinal axis. Centrally arranged in this coil body is the magnetic core (26, 126), which is fixed on both sides in the piston (3, 103) by a holding rod (27, 127) and holding discs (28, 29, 128, 129) and can be adjusted in its centre or zero-point position by screw connections. The arrangement is especially suitable for ... Original abstract incomplete. <IMAGE>
