Abstract: Изобретение относится к медицине, а именно к стоматологии, и предназначено для использования при  оценке восстановления форм зубов. Измеряют площадь окклюзионной и коронковой поверхностей зубов. Определение площади окклюзионной и коронковой поверхностей зубов проводят с помощью внутриротового сканера с последующей обработкой информации в персональном компьютере. Производят вычисление показателя индексной рельефности в процентах, как соотношение площади окклюзионной поверхности к площади коронковой поверхности каждого зуба. Причем показатель определяют у пациентов в возрасте 18 лет и заносят его данные в медицинскую карту стоматологического больного и рассматривают расчетную величину как индивидуальную норму показателя индексной рельефности для каждого зуба. В дальнейшем при лечении этих пациентов снова определяют показатель индекса рельефности зуба и проводят сравнение качества лечения, при восстановлении морфологии зуба по отношению к норме показателя индексной рельефности. Если показатель индексной рельефности равен  от 80 % и выше, ставят высокий уровень качества лечения, от 40 % до 80% - средний уровень оценки качества лечения, при ниже 40 % - низкий уровень оценки качества лечения. Способ, за счет использования количественных показателей при оценке проведенного восстановления, позволяет экспертировать работу врача–стоматолога при восстановлении коронковой части зуба, оценивать качество проведенного лечения у пациента. 2 ил., 4 табл., 3 пр.

Abstract: Bei einem magnetisch, schwimmend gelagerten superschnellen Transportsystem dient als Antrieb ein linearer Synchronmotor, der aus einem am Zug befestigten Feldmagneten (1a) und einer Reihe längs des Gleises vorgesehener Ankerspulen (2) besteht. Die Geschwindigkeit des Zuges wird mittels eines Frequenzumformers variabler Frequenz und Spannung zur Leistungsversorgung der Ankerspulen geregelt. Zur Geschwindigkeitsregelung wird die relative Lage des Feldmagneten (1a) gegenüber den Ankerspulen erfaßt und es wird ein Zug von Lageerfassungsimpulsen (4) gebildet. Ein Bezugsfrequenzmuster (9), dessen Frequenz einem Geschwindigkeitsbefehl entspricht, wird gebildet und es wird  die Phasendifferenz zwischen dem Bezugsfrequenzmuster und dem Lageerfassungs-Impulszug erfaßt. Der Antriebskraftbefehl des Linearmotors wird durch Einstellen verschiedener Grenzwerte im positiven und negativen Teil des Phasendifferenzsignals erhalten. Es wird ein mit dem Lageerfassungs-Impulszug synchrones Stromverlaufsmuster gebildet. Durch Multiplizieren des Stromverlaufsmusters mit dem Antriebskraftbefehl entsteht ein sinusförmiges Ankerstrommuster, dessen Frequenz und Scheitelwert festliegen. Der Frequenzumformer wird so geregelt, daß der Ankerstrom dem Ankerstrommuster folgt, wodurch die Fahrzeuggeschwindigkeit dem Geschwindigkeitsbefehl genau folgt.

Granted: 1984-08-23
Abstract: Die Erfindung betrifft ein Verfahren zur Bildung eines Heizelementes, bei dem ein im allgemeinen dünner Heizdraht in einer dickeren Klebefolie od.dgl. fixiert wird. Diese Heizelemente sollen sowohl glattflächig der Rückseite des Spiegelglases, als auch, bei Verwendung dünnerer Drähte, nach dem Abzug des Abdeckpapiers, glattflächig dessen Halterung anliegen. Die Herstellung solcher Elemente mit vielnadligen Nagelschablonen ist aufwendig durch die notwendige Abreinigung der anhaftenden Klebstoffreste. Des weiteren fördert die Vielnadligkeit den Verzug des Elementes bei Abzug und Verlagerung des Heizleiters. Es ist Ziel diese Nachteile auszuschließen. Die Lösung sieht vor, daß der Heizdraht (7) auf einer mit Antihaftbeschichtung ausgerüsteten Fläche einer während der Fixierung stationär verbleibenden Arbeitsplatte (1) um durch diese in axialer Richtung gleitbar geführte Stifte (4) gelegt wird. Die Länge der aus der Arbeitsplatte (1) austretenden Stifte (4) überschreitet den Durchmesser des Heizdrahtes (7) und die diesen überschreitende Endlänge ist verjüngt. Die einer Druckplatte zugeordnete Klebefolie (8) wird gegen die freien Stiftenden (5) der Stifte (4) geführt und diese durch die Folie (8) in die Arbeitsplatte (1), bei Lösung des Heizdrahtes, verdrängt. Die Stifte sind in einer Grundplatte (2) feststehend angeordnet.
