Title: Procedure and means for improving the papermaking process on a fourdrinier wire section
Inventor: MALASHENKO ALEXANDER
IPC: D21F3/00
Filed: 1986-01-27
Abstract: Procedure in the forming of a paper web and in dewatering the paper pulp suspension. A pulp suspension jet (J) is supplied onto a lower wire (11), water is drained through the lower wire (11), the fibre pulp course (Wo) is conducted into a dewatering and forming zone (L), where water is drained through the wires (11, 31) and the web (W) is conducted onto a pick-up fabric (21). In the forming zone, the joint run of the wires (11, 31) is deflected, a dewatering effect is caused such that water escapes from the pulpe course (Wo) only through the upper wire (31), a change of direction of the run of the wires (11, 31) is caused in the opposite direction, water that has escaped through the upper wire (31) is collected and said water is guided to water collecting means (40, 46), the run of the twin-wire part is deflected in a direction opposite to preceding deflection; and the joint run of the wires (11, 31) and of the pulp course conforms, starting from the single-wire initial part (11a), to sinusoidal path, the ratio of this wave's length  lambda  to the amplitude H of the wave being in the range  lambda /H = 12 to 20. The invention also concerns an upper wire unit (30), with ancillary equipment (41, 43, 45) for remodelling the Fourdrinier wire section of a paper machine.

Title: Copper wire for bonding a semiconductor device
Inventor: MORIKAWA MASAKI
IPC: C22C9/00
Filed: 1988-12-12
Abstract: The present invention eliminates the problems associated with the use of oxygen-free copper and other high-purity copper materials as bonding wires. In accordance with one aspect of the present invention, at least one rare earth element, or at least one element selected from the group consisting of Mg, Ca, Ti, Zr, Hf, Li, Na, K, Rb and Cs, or the combination of at least one rare earth element and at least one elemented selected from the above-specified group is incorporated in high-purity copper as a refining component in an amount of 0.1-100 ppm on a weight basis, and the high-purity copper is subsequently refined by zone melting. The very fine wire drawn from the so refined high-purity copper has the advantage that it can be employed in high-speed ball bonding of a semiconductor chip with a minimum chance of damaging the bonding pad on the chip by the ball forming at the tip of the wire. In accordance with another aspect of the present invention, 0.5-3 ppm of a rare earth element and/or Y is further incorporated as an alloying component in the zone-refined high-purity copper.

Title: Magnetic resonance imaging using a variable direction primary uniform field
Inventor: EHNHOLM GOSTA JAKOB
IPC: G01R33/48
Filed: 1989-01-03
Abstract: In magnetic resonance imaging a primary substantially uniform magnetic field Bo has a direction which varies with time, e.g. a rotating field. Such a field operates to average out from the magnetic field experienced by the sample being imaged at least some of the external perturbing magnetic fields so reducing sensitivity thereto. The field Bo, and gradient fields X, Y, Z which have field directions which vary synchronously with Bo, are each generated by combinations of two orthogonal coil pairs driven in quadrature or 3 coil sets at 120 DEG  driven by a 3-phase source, e.g. at 40-1000 Hz and preferably at an even harmonic of the AC power supply. Spin polarisation is by strong pre-polarising magnetic pulses or by coupling to excited electron spins. The system may be useful for imaging at lower field intensities e.g. 2000 Gauss.

Title: Control system for motor driven window
Inventor: CREED MICHAEL THOMAS
IPC: H02H7/093
Filed: 1989-03-31
Abstract: A circuit for controlling bi-directional operation of a vehicle window lift motor 12 having a toroidal coil 38 sensing counter-emf perturbations in the motor current line. An EXPRESS mode switch 98, upon momentary actuation, latches an electronic switch to operate a relay to provide continuous motor rotation for lowering the window. Subsequent momentary switch actuation unlatches the electronic switch to cut interrupt window motor current. Window lift motor stall is detected by a toroidal coil which senses loss of motor line perturbations and unlatches the electronic switch to open circuit the motor relay. <IMAGE>
