Abstract: A master tape (10) movable in a closed loop including a pinch roller transfers a mirror image to a slave tape (12) movable in a closed loop including a capstan. A thermomagnetic layer on the slave tape has a Curie temperature above which magnetic information is destroyed and below which magnetic information can be recorded on such layer. The thermomagnetic layer is heated above the Curie temperature and is accordingly lengthened by thermal expansion just before the slave tape reaches the capstan. A first guide (151) contiguous to the heater regulates the slave tape tension. A downstream portion of a peripheral surface, preferably defining a cylindrical segment, on the guide receives a pressurized fluid for sensing the tape tension in accordance with the tape width, distance from the cylinder axis, and the fluid pressure. An upstream portion of the peripheral surface receives a vacuum adjustable to vary the spacing between the slave tape (12) and the downstream portion. This regulates the tape tension. The master tape (10) is lengthened by a second guide (52) having the same construction as the first guide to compensate for the lengthening of the slave tape by the heater and the first guide, thereby producing a true mirror image on the slave tape after the slave tape has cooled to the ambient temperature. Each of the master tape and the slave tape has a particular product of the Youngs modulus, tape width and tape thickness to provide a controlled strain on the tape when the tension on the tape is regulated.

Abstract: The present invention describes a device for winding a plastic film web with the aid of a driven winding core, a web-tension measurement roll, a driven contact roll which is arranged between the winding core and the web-tension measurement roll and, for contact winding, is adjustable against the forming film roll and, during gap winding, has a distance from the film roll, and with a control device for controlling the motors as a function of the feed rate of the web corresponding to the measured web-tension force in such a manner that the winding hardness of the winding roll is influenced in a predeterminable manner. With devices of this kind, plastic webs to be processed at a subsequent time, for example to form carrier bags or refuse sacks, can be wound. To make this possible, the rolls have to be wound so as to be as straight-edged as possible, that is to say the individual layers in the film rolls must not shift out or telescope out in the axial direction during winding. Winding is therefore carried out in such a manner that the winding hardness of the film rolls decreases from the inside outwards. In order, now, during central gap winding also, to be able to wind sensitive films to form film rolls in which the winding hardness is influenced in a manner corresponding to the more sensitive film types, the invention proposes that, during contact winding, the torque of the winding motor be controlled corresponding to the increasing roll diameter and the contact roll be driven with a speed corresponding to the web tension-force and that, during gap winding, the winding motor be controlled in its speed, corresponding to the measured web-tension force. <IMAGE>

Abstract: A printer capable of completely erasing printed characters while reducing noise which may be generated during the erasure. After an erase key is manipulated and the holder member is moved to its erase position, a motor is energized and driven at a motor current level of I1 and I2 from a time to when the erasing operation starts. A print hammer strikes onto a printing paper through a type and a correction ribbon at a hammer speed of V1. Thereafter, motor current level of I3 is applied to the motor, so that the print hammer presses the printing paper at a contacting pressure of P1. In the subsequent erasure operation, the motor current level of I11 and I12, which are smaller than I1 and I2 in the first erasure are applied to the motor. Thus, the hammer speed when striking onto the printing paper by the hammer is lower than V1. Accordingly, contacting pressure of the print hammer onto the printing paper becomes P11, which is smaller than P1 of the first erasure.

Title: Two dimensional profiling with a contact force atomic force microscope
Inventor: MARTIN YVES
IPC: G01B21/30
Filed: 1993-09-21
Abstract: Two dimensional profiling of samples, such as integrated circuits containing trenches or lines, is accomplished using contact force atomic force microscopy by controlling the tip position responsive to the real-time measured local slope of the surface in contact with the tip. The tip is brought so close to the surface of the sample to be investigated that the forces occurring between the atoms at the apex of the tip and those at the surface cause a spring-like cantilever to deflect. The deflection of the cantile ver provides a variation of a tunnel current, and that variation is used to generate a correction signal which can be employed to control the distance between the tip and the surface of the sam ple, in order, for example, to maintain the force between the tip and sample constant as the tip is scanned across the surface of the sample by means of an xyz-drive. The tip (10) which is coupled to the cantilever (12) of an atomic force microscope is disposed within a trench (14) located in the sample substrate (20), the sidewalls (16, 18) of which are to be profiled. Preferably the tip (10) has a "boot" shaped cross-section in order to enable sensing of a bottom corner of a trench or line.

Abstract: A low-voltage output driving circuit capable of preventing the generation of leakage current. The circuit includes a transfer gate GT installed between the output S₂ of a first CMOS inverter INV C1  and the node S₁ at the gate of an MOS transistor PT₃ for active pull-up. At the same time, a reference voltage V REF  and a voltage level V OUT , which corresponds to the voltage level of the output line of the signal S OUT , are compared by a comparator CMP. When the voltage V OUT  is lower than the reference voltage V REF , the transfer gate GT is set to the ON state, and the output of the first CMOS inverter INV C1  is sent to the gate of the transistor PT₃ for active pull-up. The comparator CMP is installed so that when the voltage level V OUT  is higher than the reference voltage V REF , the output of the first CMOS inverter INV C1  is prevented from reaching the gate of the transistor PT₃ for active pull-up. Thus, although the input and output can take on any state, the generation of leakage current which flows toward the power supply from the output side can be prevented.

Abstract: Video images of varying resolutions are derived from one video signal (VIDIN) with high bandwidth efficiency by employing a new two-layer video coding technique using spatial scalability in which the prediction taken from one layer (1140) is combined with the prediction taken from the other layer (1180), and the combined prediction is used to code one of the layers (in 1180). In an illustrative example of the invention employing a base-layer and an enhancement-layer, the spatially interpolated base-layer (on 1170) is combined, by the selection of appropriate weights, with the motion compensated temporal prediction of the enhancement layer to generate the prediction used to encode the enhancement-layer (in 1180). Weights are selected based on a calculation of the sum of the absolute differences, or the sum of the squares of the differences between the prediction and reference macroblocks to produce the prediction giving the best bandwidth efficiency. This weighting process is called spatio-temporal weighting.

Abstract: An image processing system encodes a natural image into a segmented or mosaic image having well-defined edges and a residual image. The segmented image is encoded using a lossless encoding technique while the residual image is encoded using a lossy technique. This encoded image may be recorded on a video tape such that the segmented image may be recovered in picture-in-shuttle modes such as fast forward and fast rewind. In addition, the recorded image may be decoded and reencoded through several generational levels without experiencing significant degradation in perceived image quality. The segmented image is produced by an encoder which employs a multi-scale edge finder that is able to resolve transitions occurring over two, four and eight pixels into an edge located between two pixels. In addition, the lossless encoder includes circuitry which chain-encodes the segmented image into a low-resolution image and multiple complementary images such that the low-resolution image may be stored as a single data packet and, thus, recovered as a unit from the tape in picture-in-shuttle mode.

Abstract: The printing plate (8) has edges bent into a Z-shape which hook over movable sharp edges (2,3) on either side of a groove in the printing cylinder (1). There is a trapezoid-section bar (21) which can engage the second bends on the ends of the Z-shaped ends of the printing plate. When the printing plate is fitted, cylinders to which the sharp edged (2,3) wedges are attached are rotated to bring these edges away from the centre of the big roller (1) and away from each other. After the first sharp bends in the plate are hooked over the edges, the edges are rotated toward each other to tension the plate. The trapezoid section bar is moved to trap the ends of the plate against the inside surfaces of the wedges. The wedges and small cylinders are shaped to present a smooth cylindrical outer surface when the ends of the printing plate are clamped.
