Title: Compacting of paper and similar fiber webs
IPC: D04H/
Filed: 1968-02-27
Abstract: In a press for the compressive shrinkage of paper, the hard surface on to which the web is pressed has a low frictional drag, so that webs of high water content can be treated. In particular, the water-to-fibre ratio is between 1:1 and 3:1, and the frictional drag is not more than 85% of that between a polished chromium surface and a similar web. Suitable surfaces are: fluorocarbon polymer metal surface plated with chromium, polished, then etched or pitted, e.g. by sandblasting, and coated with a fluorocarbon polymer (such a surface is still usable when the polymer on the peaks of the metal surface has worn away, leaving metal exposed over a minor proportion of the working surface) metal surface plated with chromium treated or applied to give a surface of small closely spaced convex modules, e.g. by polishing a steel surface, then blasting it and finally plating it. Because of its high water content, the treated sheet may be machine glazed. The shrinking apparatus may be, apart from its coefficient of friction, similar to that of U.S. Patent 2,624,245.

Title: Method of manufacturing a semiconductor device comprising a junction field-effect transistor
IPC: H01L27/082
Filed: 1968-06-28
Abstract: An N-channel PN-junction-gate field effect transistor is formed in an isolated island in an N-type epitaxial layer 32 on a P-type substrate 31, and is insulated from the substrate 31 by means of an N-type zone 34 formed by redistribution of impurities from a prediffused region in the substrate surface. A buried P-type gate region 33 of the field effect transistor is formed similarly, and is joined to the surface by an annular P-type surface-diffused region 36. A second diffused gate region 38 defines, with the buried region 33, the channel 30. The conductivity types may be reversed. The island may be isolated from the remainder of the epitaxial layer 32 by insulation-filled grooves or by diffused walls 43. In the embodiment the field effect transistor is integrated in a Si body with complementary PNP and NPN transistors. The collector region 45 of the PNP transistor is a buried region formed in the same manner as the gate region 33 of the field effect transistor, and an N-type isolating region 59 is also provided for this device. The NPN transistor has a low resistivity N-type buried layer 46 comprising part of its collector region. The substrate may have a non-homogeneous composition or may comprise a P-type layer on an N-type body. Phosphorus and boron are referred to as suitable dopants. Diodes and passive elements such as resistors may also be integrated with a field effect transistor made in accordance with the invention.

Patent ES-376145-A1 (ES)
Title: Speed dictation apparatus for elevator motor control system
IPC: B66B1/30
Filed: 1970-02-02
Abstract: A high-speed lift car is operated by a hoist motor controlled by a speed regulator which receives a time-dependent signal during acceleration of the car. On receipt of a signal requiring the car to stop at a landing, the time-dependent signal changes to a deceleration command, and the manner of deceleration is brought into conformity with a distance-dependent signal generated by a landing selector mechanism. In the system shown, a lift car 10 is driven by a motor 14 which also drives a tachogenerator 17 to provide a voltage proportional to the speed of the car. The motor is supplied through a control 15. A tape 19 drives the shaft 694 of a landing selector device 22, the shaft being connected by way of gears GB1-3 with switch-controlling cams AFDC, HXC, and with sliders of potentiometers POT1-2. One input to the motor control 15 is provided by an integrating operational amplifier MIA, which in turn receives a time-controlled signal through function generators connected to a capacitive circuit in series with input resistor DAR1, Fig.2 (not shown). Logic diagrams and corresponding NAND circuits are described with reference to Figs.3a, 3b and 4 (not shown). In operation, when a start signal 13 received, an acceleration function generator charges the capacitive circuit and the lift 13 caused to move with increasing acceleration until a desired acceleration is reached. This 13 held cbnstant until the desired maximum velocity is approached. This is signalled by a comparator circuit embodying a fixed reference voltage. Subsequently, the car speed is clamped at this desired maximum. When the car reaches a point a predetermined distance away from the desired stop, a decelerating function generator takes over, but before the car is halted, a further comparator circuit operates to bring in a distance-dependent signal defined by the drive of the cams and potentiometers by gears GB1-3. This signal forces the amplifier MIA to provide an output to the control 15 which ensures stable deceleration of the car until it is close to the selected landing, at which point contacts HXA1 are opened and contacts HXA2 are closed, so that control is removed from the amplifier MIA and transferred directly to the potentiometer POT2 which brings the car rapidly and accurately to the landing level. In the case of a short journey, the car is prevented from reaching its full rated speed since it could not be stopped in the required distance with the normal deceleration rates. In this situation, the rate of change of acceleration is constrained to a negative value when the car is still in the accelerating phase.
