Description
Электрические печи дл разрушени гистологических препаратов, содержащие термостойкую пластину, электронагреватель и корнус , известны.Electric ovens for destroying histological preparations containing a heat-resistant plate, an electric heater and a corn bed are known.
Предлагаема печь отличаетс от известных тем, что термостойка пластина помещена в днище корпуса, снабженного щтуцерами и смотровым окном, а электронагреватель выполнен в виде полупроводниковой пленки на поверхности этой пластины. Такое выполнение печи позвол ет использовать термостойкую пластину в качестве предметного стекла микроскопа дл наблюдени за всеми стади ми разложени в атмосфере любого газа.The proposed furnace differs from those known in that the heat-resistant plate is placed in the bottom of the case, equipped with shtutsers and viewing window, and the electric heater is made in the form of a semiconductor film on the surface of this plate. This embodiment of the furnace makes it possible to use a heat-resistant plate as a microscope slide for observing all decomposition stages in the atmosphere of any gas.
Предметное стекло покрыто материалом, обладающим нар ду с полупроводниковыми свойствами, повыщенными по сравнению с материалом предметного стекла показателем преломлени , например, двуокисью олова, Это позвол ет использовать печь при работе с микроскопом как в проход щем, так и отраженном свете.The slide is covered with a semiconductor property that has a refractive index, for example tin dioxide, compared to a slide glass material. This allows the oven to be used when working with a microscope in transmitted and reflected light.
На фиг. 1 изображена предложенна печь, общий вид; на фиг. 2 - то же, без крыщки.FIG. 1 shows the proposed furnace, general view; in fig. 2 - the same, without a lid.
Предлагаема электрическа печь содержит выполненный из металла цилиндрический корпус 1 с герл етически завинчивающейс крыщкой 2. Диаметр корпуса равен диаметру предметного столика микроскопа. В центральной части корпуса и крыщки имеютс смотровыеThe proposed electric oven contains a cylindrical body made of metal 1 with a gerlatetically screwed lid 2. The case diameter is equal to the diameter of the microscope stage. In the central part of the body and the covers there are viewing points.
окна 3, в которые вставлены термостойкие стекла. На крыщке установлено откидное зеркало 4 дл наблюдений в отраженном свете. На дне корпуса укреплены две керамические подставки 5 с токопровод щими щинками 6 и пластинчатыми пружинами 7. Токопровод щие шинки соединены проводами 8 с гнездом дл электровилки, расположенным на корпусе печи.Windows 3, which are inserted into heat-resistant glass. A flap mirror 4 is mounted on the cover for observation in reflected light. At the bottom of the casing, two ceramic supports 5 with conductive flaps 6 and lamellar springs 7 are fastened. The conductive bushes are connected by wires 8 to a socket for electric knobs located on the furnace body.
На боковой поверхности корпуса имеютс также два щтуцера .9 с кранами дл подачи в камеру печи азота или кислорода. Под одной из токопровод щих щинок размещен датчик термоэлектрического пирометра (на чертеже не показан).On the side of the housing there are also two plugs .9 with cranes for supplying nitrogen or oxygen to the furnace chamber. A thermoelectric pyrometer sensor is placed under one of the conductive ports (not shown in the drawing).
Разрушение исследуемых препаратов производитс на термостойкой пластине, используют в качестве предметного стекла микроскопа .The destruction of the studied drugs is carried out on a heat-resistant plate, used as a microscope slide.
Одна сторона пластины покрыта полупроводниковой пленкой, замен ющей электронагреватель . Така пленка может изготавливатьс , например, из двуокиси олова, с добавками сурьмы, хлористого железа, цинкаOne side of the plate is covered with a semiconductor film replacing the electric heater. Such a film can be made, for example, from tin dioxide, with antimony, iron chloride, zinc additives.
и т. д. дл увеличени термостойкости пленки и ее электрического сопротивлени . При работе с печью на термостойкую пластину (на ту се поверхность, на которую нанесена полупроводникова пленка) помещают исследуetc., to increase the heat resistance of the film and its electrical resistance. When working with a furnace, a heat-resistant plate is placed on the surface on which the semiconductor film is applied.
