Patent EP-0349170-A2 (EP)
Inventor: MCGOVERN KEVIN MICHAEL
IPC: F02B39/04
Filed: 1989-06-16
Abstract: An intake manifold (18) for an engine (10) includes a Roots-type supercharger (26) having a torsion damping mechanism (54) for reducing audible rattle of timing gears (72,74) which prevents contact of meshed lobes (28a,29a) of the supercharger rotors (28,29). The damping mechanism includes torsion springs (98,100) preloaded against each other. Torsion spring (98) has a low spring rate for attenuating torque fluctions or spikes during non-supercharging, low engine speed modes of operation. Spring (100) has a relatively high spring rate and functions as a shock absorber during engine shut down and during rough engine operation.

Abstract: 1. During the processing of digital signals, short-term interference pulses superimposed on the input signal must be filtered out so that the serviceability of the digital signal processing unit is not impaired. It is therefore the object of the invention to build up a filter logic unit which suppresses short-term interference pulses, the duration of the suppressible interference pulses being variable. 2.2 This is achieved by the fact that the input signal is first synchronised with a predetermined clock and is subsequently delayed n-times by one clock period, interference pulses with n-times the clock period duration being filtered out. The signal delayed n-times and the input signal synchronised with the clock go to an exclusive-OR gate, the output of which goes to the control input of a multiplex D-type flip-flop and the output of which flip-flop is the filtered signal. The exclusive-OR gate in this case drives the multiplex D-type flip-flop in such a manner that, with different input levels at the exclusive-OR, that is to say if, for example, an interference pulse is present, the existing output signal is obtained and, with an identical input level, that is to say when the undisturbed signal is present, this is switched through to the output. 2.3 Devices with digital signal processing. <IMAGE>

Abstract: A method is decribed for attaching ciruit chips (1) to a flexible substrate (2) (laminate) using controlled chip collapse connection technology (C-4). The substrate is "tinned" with an alloy of eutectic composition (9) in its contact region with the solder balls (7) on the base of the chip. The alloy and the solder are chosen such that they are miscible. The system temperature is raised above the alloy melting point thus causing the alloy and the solder to mix, the mixture composition moving away from the eutectic composition with time and thus raising its melting point. Eventually the mixture melting point is higher than the temperature at which the system is maintained and the mixture solidifies to form a contact. In this way contact between the chip and the flexible substrate can be effected at a temperature below the melting point of the pure solder and lower than one which would result in degradation of the laminate adhesive.

Title: Method for flattening tree trunks
IPC: B27C1/00
Filed: 1991-01-29
Abstract: A method serves for flattening logs (10) showing a curved longitudinal center line (10a). The logs (10) are conveyed in horizontal position in their longitudinal direction, with their convex side (11) up and their concave side (12) down. The concave side (11) of the logs (10) is flattened from below in the area of their butt ends (27). In order to optimize the yield in wood, the logs (10) are measured before carrying out the flattening step, in a position where they are supported on a reference plane (13) by the end points (20, 22) of their concave side (12) only. The geometrical position of a first point (26) of the log (10) is determined on the convex side (11) as its elevation above the reference plane (13). The butt end (27) of the log (10) is then lowered, while keeping the end point (20) opposite the butt end of the log constantly in contact with the reference plane ( 13), until the first point, which defines the lowest point between the said highest elevation (23) and the said butt end (27) on the said convex side (11), comes to lie at a level above the reference plane (13) which corresponds to the diameter (d0) of the said log (10) at its end opposite the said butt end. Thereafter, the logs (10) are flattened in this lowered position up to the reference plane (13) (FIG. 1).
