нокристалла из расплавленного металла<br />

(4) в кварцевой ампуле (2), дно которой<br />

выполнено конусообразным с углом 40°,<br />

помещенной в печь (1), подключенную к<br />

электронному устройству для поддержания<br />

в ней постоянной температуры в<br />

300°C в течение всего процесса выращивания<br />

с градиентом температуры равным<br />

7°С/см. Первое ядро кристаллизации Sb,<br />

которое служит началом для ориентированного<br />

роста, расположено таким образом,<br />

чтобы ось третьего порядка образовала<br />

с осью ампулы угол 20°.<br />

(54) Pompă electrohidrod<strong>in</strong>amică multietajată<br />

(57) Invenţia se referă la pompele electrohidrod<strong>in</strong>amice<br />

pentru pomparea lichidelor dielectrice.<br />

Pompa electrohidrod<strong>in</strong>amică multietajată<br />

conţ<strong>in</strong>e un corp dreptunghiular (5), în care<br />

sunt amplasate etajele (6, 7) pompei, unde<br />

fiecare etaj conţ<strong>in</strong>e câte doi electrozi − emitor<br />

(E) şi colector (C), executaţi în formă de grilaje<br />

d<strong>in</strong> fire înt<strong>in</strong>se paralel. Pe firele emitorului<br />

(E) sunt depuse acoperiri izolante cu<br />

perforaţii d<strong>in</strong> partea colectorului (C). Perforaţiile<br />

acoperirii izolante a emitorului (E) sunt<br />

executate de o lungime egală cu 0,2…0,5 d<strong>in</strong><br />

lungimea circumfer<strong>in</strong>ţei firului. D<strong>in</strong> partea<br />

superioară a etajelor pe firele colectorului (C)<br />

sunt depuse acoperiri izolante pe 0,2…0,5<br />

d<strong>in</strong> lungimea circumfer<strong>in</strong>ţei firului. În acoperirile<br />

izolante ale firelor colectorului (C) sunt<br />

executate perforaţii în formă de tăieturi,<br />

transversal firului, pe toată lungimea acoperirii<br />

izolante şi cu lăţimea de 0,02…0,5 mm.<br />

Raportul distanţei d<strong>in</strong>tre perforaţiile colectorului<br />

(C) la <strong>in</strong>terstiţiul d<strong>in</strong>tre emitor (E) şi colector<br />

(C) al unui etaj este de 0,4…1,0.<br />

(54) Multistage electrohydrodynamic pump<br />

(57) The <strong>in</strong>vention relates to electrohydrodynamic<br />

pumps for pump<strong>in</strong>g dielectric liquids.<br />

The multistage electrohydrodynamic pump<br />

comprises a rectangular hous<strong>in</strong>g (5), <strong>in</strong><br />

which are placed the stages (6, 7) of the<br />

pump, where each stage conta<strong>in</strong>s two electrodes<br />

− emitter (E) and collector (C), made<br />

<strong>in</strong> the form of arrays of parallel-stretchedires.<br />

On the wires of the emitter (E) are applied<br />

<strong>in</strong>sulation coat<strong>in</strong>gs with perforations from the<br />

end of collector (C). The perforations of the<br />

<strong>in</strong>sulation coat<strong>in</strong>g of the emitter (E) are made<br />

of a length equal to 0.2…0.5 of the length of<br />

wire circumference. On the upper side of the<br />

stages on the wires of the collector (C) are<br />

applied <strong>in</strong>sulation coat<strong>in</strong>gs on 0.2…0.5 of the<br />

length of wire circumference. In the <strong>in</strong>sulation<br />

coat<strong>in</strong>gs of the wires of collector (C) are<br />

made perforations <strong>in</strong> the form of slits, transversely<br />

to the wire, on the full length of the<br />

<strong>in</strong>sulation coat<strong>in</strong>g and with a width of<br />

0.02…0.5 mm. The ratio of the distance between<br />

the perforations of the collector (C) to<br />

the gap between the emitter (E) and collector<br />

(C) of one stage is equal to 0.4…1.0.<br />

(54) Многоступенчатый электрогидродинамический<br />

насос<br />

(57) Изобретение относится к электрогидродинамическим<br />

насосам для перекачки диэлектрических<br />

жидкостей.<br />

Многоступенчатый электрогидродинамический<br />

насос содержит прямоугольный<br />

корпус (5), в котором расположены ступени<br />

(6, 7) насоса, где каждая ступень содержит<br />

по два электрода − эмиттер (E) и<br />

коллектор (C), выполненных в виде реше-
