Abstract: A compression-type semiconductor device comprises a semiconductor element and compression means (13, 14) for maintaining the semiconductor element in a compressed state. The semiconductor element comprises a semiconductor substrate (21) having first and second major surfaces (21a, 21b). The semiconductor substrate (21) has a first semiconductor region including a plurality of semiconductor sections. Each semiconductor section is composed of a plurality of divided semiconductor segments (22) of a first conductivity type projecting on the first major surface (21a) of the substrate (21). These segments (22) have substantially rectangular top surfaces which are present in a plane. The segments (22) in each semiconductor section have approximately the same size and are arranged so that the long sides of adjacent rectangles face each other. A second semiconductor region (23) of a second conductivity type opposite to the first conductivity type is formed in the first major surface (21a) of the substrate (21), surrounding the individual semiconductor segments (22). On the first semiconductor region first electrode means including separate electrode members (27) is formed. The separate electrode members (27) each substantially cover the top surfaces of the segments in each of the semiconductor sections, and electrically connect these segments (22). Second electrode means (28) is formed on the exposed surface of the second semiconductor region (23). Third electrode means (29) is formed on the second major surface (21b) of the semiconductor substrate (21). Insulation means covers the second electrode means (28) between the adjacent semiconductor segments (22) in each semiconductor section.

Abstract: A process for selectively hydrogenating a fatty acid derivative, such as a triglyceride fat or oil, having fatty acid moieties containing more than two double bonds as well as fatty acid moieties containing two double bonds comprises catalytic hydrogenation in the presence of at least 1.8 mol of ammonia per litre of fatty acid derivative. The high level of ammonia present allows increased selectivity to occur such that the fatty acid moieties containing more than two double bonds are highly selectively hydrogenated to moieties containing a two double bonds. Depending on the catalyst and derivative employed S II  values of at least 10 and trans-isomerisation of less than 5 mol% can be derived.

Abstract: A roll stand has a frame, a pair of small-diameter and substantially parallel working rolls defining a workpiece nip, and respective journal blocks supporting the working rolls in the frame for rotation about substantially parallel axes flanking the nip. These working-roll journal blocks and the respective working rolls can be axially shifted in the frame and the working rolls can be bent positively and negatively, that is respectively convex and concave toward the workpiece. A pair of large-diameter and substantially parallel backup rolls flank and bear toward the nip on the working rolls. Respective journal blocks support the backup rolls in the frame for rotation about substantially parallel axes flanking and generally coplanar with the working-roll axes. A strip is passed repeatedly in a multipass run through the nip generally perpendicular to the plane while the working rolls are pressed against the workpiece to reduce its thickness. The working rolls are axially displaced relative to the workpiece a plurality of times during the run to change the region of contact between the workpiece edges and the working rolls during the run. The working rolls are also bent at least to maintain the workpiece thickness downstream of the nip generally uniform.

Abstract: An improved method and apparatus for bonding together juxtaposed webs which are subject to being ultrasonically bonded together such as, for example, thermoplastic films or non-woven thermoplastic webs or elastomeric films to form a laminate as the webs are being driven forward at a relatively high velocity. The apparatus includes an ultrasonic hom and a power-rotated anvil cylinder which define a bonding passageway therebetween, and a rotatable pressure roll which is biased towards the anvil adjacent the downstream end of the bonding passageway to apply a predetermined level of compressive force to the bonded regions of the laminate issuing from the passageway before the bonds in the bonded regions become fully set upon cooling. In a preferred apparatus embodiment of the invention the anvil has a relief-type bonding pattern on its circumferential surface; and the pressure roll is sufficiently rigid and so configured and disposed that substantially only the portions of the laminate juxtaposed raised elements of the bonding pattern are subjected to such post-bonding compression.

Abstract: In an automotive windshield wiper control system, a rain sensor provides a rain condition-indicative signal useful in controlling the wiper in its intermittent operation mode. That signal is integrated to yield a value representing rain accumulation on the windshield, and when the integrated value exceeds a given threshold, the wiper is reciprocated once to clear the windshield. In order to prevent a rhythmic wiper operation, the signal integrator is disabled during wiper operation so that the integrated value will not approach the threshold too soon after or even before the end of the preceding wiper operation cycle.

Abstract: The present invention relates to a method and an apparatus for an improved electrically programmable read only memory device. Each device comprises a plurality of addressable bits with each bit having two storage cells. If one of the storage cells is charged and the other is uncharged, then the bit is in one logical state; if the one cell is uncharged and the other is charged, then the bit is in the other logical state. Voltage from the storage cells are detected differentially. As a result, greater speed in readout of the device can be achieved.

Abstract: The invention relates to a method of processing data for recognising unknown characters of a known character set based in part upon the frequency of occurrence of said characters and to apparatus for performing the method. The method comprises the steps of scanning the unknown characters and generating image data representing the unknown characters, storing the generated image data, and applying to the stored image data discriminating tests for recognition purposes. 
<??>The method is characterised by the steps of applying to the stored image data a first set of discriminatory tests for identifying whether the image data represents a first group of characters and for recognising the image data that represents characters of the first group of characters. The characters of the first group have a relatively high frequency of occurrence and the first group contains less than all of the characters of the character set. The method also includes subsequently applying to the unrecognised image data a second set of discriminatory tests for identifying whether the unrecognised image data represents a second group of characters and for recognising the image data that represents characters of the second group of characters. The characters of the second group have a lower frequency of occurrence than the characters of the first group and the second group contains at least some characters not in the first group of characters. 
<??>The method may also include the step of sequentially applying to any unrecognised data from the application of the second set of discriminatory tests at least one additional set of discriminatory tests. Each additional set of discriminatory tests is for identifying the unrecognized image data that represents a respective additional group of characters and for recognizing the image data that represents characters of the respective additional group of characters. The characters of each additional group of characters have a lower frequency of occurrence than the characters of the preceding group of characters.

Abstract: An electron energy beam (28) discontinuously scans a sample (32) and at each scan position produces a thermal wave in the sample, there being infrared radiation emitted from the thermal wave. All of the infrared radiation emitted from the heated areas of the sample is collected by an ellipsoidal collector (34) and directed by reflection to an infrared detector (44), the sample and detector being at the foci of the collector (34), to give a two-dimensional image of the sample. A computer system (52) is used to control data acquisition, storage, processing and image display, and also modulation and scanning of the beam (28). Surface, on the surface, and sub-surface structure of the sample can be detected, for example to reveal defects, or surface particles.
