Patent EP-0556790-A1 (EP)
Inventor: MURRAY CAMERON T
IPC: B32B27/00
Filed: 1993-02-17
Abstract: The invention provides a polyimide substrate bearing thereon a disordered amorphous surface layer that provides improved adhesion when said polyimide substrate is used in polymer or metal laminates, wherein said surface layer is formed by the process of:
     a) providing a polyimide substrate having an ordered amorphous surface zone, and   b) irradiating at least a portion of the depth of said ordered amorphous surface zone with radiation from a pulsed energy source that produces pulses of sufficient duration and intensity to heat a portion of said surface zone to a temperature above the glass transition temperature but below the decomposition temperature, thus transforming said zone into an amorphous surface layer,   c) rapidly quenching said amorphous layer to a temperature below the glass transition temperature before the molecules comprising said disordered amorphous surface layer can reorient to the ordered amorphous state.    The amorphous surface layer has a chemical composition unchanged from and identical to that of the ordered amorphous bulk phase but having physical characteristics that are different from that of the bulk phase. The solubility, coefficient of friction, antireflectivity, and anisotropic conductivity are greater and the density, birefrengence, and ultraviolet polarization are less in the amorphous layer than in the ordered amorphous bulk polymer.

Abstract: A control device for controlling mold oscillation in a continuous casting machine comprises a horizontal position detector, an open-close control device and hydraulic cylinders. The horizontal position detector is attached to a piston rod (16) of the hydraulic cylinder for detecting an actual position of long-side copper plates (13) of a mold (10). The open-close control device further comprises a reference position compensation circuit where a predetermined offset value is received. The reference position compensation circuit produces a compensation signal with which a target position of the long-side copper plates (13) is modified. The open-close control device (23') controls the hydraulic cylinders according to the compensation signal such that a deviation between the actual horizontal position and the target horizontal position of the long-side copper plates (13) becomes equal to the offset value.

Abstract: A semiconductor acceleration sensor has an inner weight member (22b) supported by a supporting member (22a) through a pair of first torsion bars (22d) and an outer weight member (22c) supported by the inner weight member through a pair of second torsion bars (22e). The components of the force being sensed are thus converted into twisting displacements for sensing. The displacements may be converted into variations of capacitances of two respective pairs of capacitors (C1 to C4) on the axes of the torsion bars. Alternatively, the displacements may be converted into electrical signals by piezo resistance elements (43a - 43d; Fig. 11) formed in the torsion bars (42d, 42e).

Abstract: A pump is described with at least one reservoir (7) of a liquid additive to which an appropriate pressure is applied from a motor fluid and the additive is removed into a duct (23). The procedure includes the following steps:   - at every instant, a flow of gas and/or of liquid is regulated by a flow rate regulation valve upstream (1, 30) of the reservoir (7); - at every instant, a volume is measured in the reservoir containing the additive; - at every instant, the flow rate of additive delivered is determined by processing means (28), and the flow rate of additive thus calculated is compared with a previously recorded flow rate datum value; and - a signal is sent by the said processing means making it possible to act on the gas and/or liquid flow rate regulation valve (1), in such a way as to deliver the additive, at any instant, at a flow rate substantially identical to that corresponding to the datum value.   More precisely, at any instant the pressure of process fluid is measured, and the flow rate regulation valve is slaved to this pressure measurement.

Abstract: A fuel injection system for an internal combustion engine, such as a dual fuel diesel/gas engine of the type requiring an overall system turn-down ratio capability, from maximum fuel flow rate to minimum flow rate, on the order of 100 to 1, employs a conventional variable displacement primary pump (10) having a turn-down ratio substantially less than the overall system ratio. The output of the primary pump (10) branches to supply two parallel fuel conduit paths (14,16). Each path includes a pressure actuated shut-off valve means (22,24). The primary shut off valve means (22) opens to permit flow through the primary path (14) to the engine at pressures in excess of a relatively high value. The secondary shut-off valve means (24) opens to permit flow through the secondary path (16) in response to a relatively lower pressure at the pump outlet (12). And, a fixed quantity fluid dispenser (26) in the secondary flow path (16) operates in response to opening of the secondary shut-off valve means (24), to displace a fixed quantity of fuel through the secondary path (16) and into the engine. 
     In general, the secondary path (16) prevents the build-up of sufficient fuel pressure at the output of the primary pump (10) to open the primary shut-off valve means (22) when the variable output rate of the primary pump (10) is set at the lowest part of its range. When the output of the primary pump (10) is set sufficiently high, pressure builds in the outlet line (12) of the primary pump (10) because the delivery rate of the primary pump (10) exceeds the rate at which fluid can be disposed of in the secondary path (16); the additional fuel displaced by the primary pump (10) is delivered to the engine accordingly, through the primary path (14).

In addition, higher natural torsion frequencies are intended to be achieved on the rotor, that is, the construction is to be made less sensitive by simple modifications to the squirrel cage in order to prevent the resonance effects. This object is attained in that respectively two, three or more short-circuit rods are guided together to rod assemblies at their ends, and these are connected to the short-circuit rings with material-to-material bonding.
