In the figure, 1 and 1' are two focal points each.
A spheroidal mirror with F 1 , F 2 and F 1 ′, F 2 ′,
F 2 and F 2 ′ are matched, and F 1 , F 2 , F 1 ′, and F 2 ′ are arranged on a straight line.

種結晶４の上に新しい結晶を成長させる。 The spheroidal mirrors 1 and 1' are comprised of bell-shaped reflecting surfaces cut along a plane perpendicular to the rotational axes F 1 -F 2 , F 2 ′-F 1 ′ of the spheroid and including F 2 , F 2 ′. It's on. Reference numerals 2 and 2' are filaments of a halogen lamp or the like which serve as heat radiation sources and are wound into substantially plate shapes, and are placed so as to be located above the focal points F 1 and F 1 ' of the spheroidal mirrors 1 and 1'. As objects to be heated, a crystal rod 3 and a seed crystal 4 are installed vertically so that their respective axes coincide, and the joint between the end surface of the crystal rod 3 and the end surface of the seed crystal 4 is connected to the above-mentioned spheroidal mirror. 1 and 1' at the focal points F 2 and F 2 ', the above-mentioned junction is melted to form a melting zone 5, and the seed crystal 4 and the crystal rod 3 are gradually moved downward relative to each other. While growing a new crystal on top of the seed crystal 4.
ここで板状のフイラメント２，２′は、通常は
第３図に拡大して示したように素線６を板状に近

放出の立場で考えると、板状フイラメントは最も
発光量の多いＡ面、２番目に発光量の多いＢ面、
最も発光量の少ないＣ面の３種類の面から構成さ
れている。 Here, the plate-shaped filaments 2, 2' usually have a shape in which strands 6 are wound into a rectangular parallelepiped shape similar to a plate shape, as shown in an enlarged view in FIG. Considering this from the perspective of light emission, the plate-shaped filament has the A side with the highest amount of light emission, the B side with the second highest amount of light emission, and the second side with the highest amount of light emission.
It is composed of three types of surfaces, the C-plane which emits the least amount of light.
一方、第１図及び第２図のような２つの回転楕
円面鏡を組合わせた構造では、２つの回転楕円面
鏡が交叉する円形の平面すなわち接合面が存在す

失される。一方、フイラメントから出て回転楕円
面鏡の回転軸F1−F2，F2′−F1′に垂直な方向に向
かう光は、効率よく溶融域へ集光される。 On the other hand, in a structure in which two spheroidal mirrors are combined as shown in Figures 1 and 2, there is a circular plane where the two spheroidal mirrors intersect, that is, a joint surface, but it comes out from the filament and joins. Light directed directly at the surface is not effectively focused onto the melting zone and is mostly lost. On the other hand, light emitted from the filament and directed in a direction perpendicular to the rotation axes F 1 -F 2 , F 2 '-F 1 ' of the spheroidal mirror is efficiently focused on the melting region.
ところで第１図、第２図に見るごとく、板状フ
イラメントを使用した従来の装置では、２番目に
発光量の大きなＢ面が損失の大きな接合面に向つ
ており、最も発光量の小さなＣ面が溶融域への照
射効率の良い方向に向いているため、全体の照射
効率が悪くなつていた。 By the way, as shown in Figures 1 and 2, in the conventional device using a plate-shaped filament, the B plane, which has the second largest amount of light emission, faces the bonding surface with the largest loss, and the C plane, which has the smallest amount of light emission, Since the irradiation efficiency of the molten region was high, the overall irradiation efficiency was poor.
このように従来の装置ではランプが輻射する熱
線の利用効率が悪く、高融点の材料を溶融可能に
し所望の結晶を育成する観点からはその持てる能
力を充分に発揮し得ないでいた。 As described above, conventional devices have poor efficiency in utilizing the heat rays radiated by the lamps, and have not been able to fully utilize their capabilities from the viewpoint of melting high melting point materials and growing desired crystals.
本考案は、このような従来の欠点を解決し、同

イラメントのＣ面を被加熱物に対面させて設置す
ることにある。以下図面に従つて説明する。 The present invention solves these conventional drawbacks and provides a radiation heating device equipped with a plate-shaped filament so that materials with higher melting points can be melted with the same power consumption. The feature is that the C side of the plate-shaped filament is placed facing the object to be heated. This will be explained below with reference to the drawings.
第４図は、本考案の一実施例についてその横断

一な加熱が可能となり、良質の結晶を成長するこ
とができるようになつた。 That is, in the conventional device shown in FIGS. 1 and 2, the B side of the plate-shaped filament shown in FIG. 3 faced the bonding surface, whereas in the conventional device shown in FIGS. In the proposed embodiment, the C-plane, which emits the least amount of light, faces the bonding surface with the greatest loss, and the A-plane and B-plane, which emit the most amount of light, face the direction with the highest irradiation efficiency. As a result, the efficiency of light irradiated to the melting region is increased by about 5% compared to the conventional method, making it possible to melt materials with higher contact points. The radiation heating device of the present invention can now grow single crystals of materials at temperatures exceeding 2000°C, which cannot be easily melted using conventional devices. Furthermore, the amount of change in the light intensity distribution in the circumferential direction of the light irradiated to the melting area ((maximum light intensity density - minimum light intensity density) ÷ average light intensity density)
This is a 10 to 50% improvement over conventional methods, allowing for more uniform heating and the growth of high-quality crystals.

同一電力でより高融点の材料の溶融が可能とな

た。 In this way, by implementing the present invention, it is possible to increase the efficiency of light irradiated to the melting region by about 5%,
It demonstrated outstanding effects that expanded the limits of technology, making it possible to melt materials with higher melting points with the same amount of electricity, and also to achieve more uniform heating.

る。 The essential condition of the present invention is to install the plate-shaped filament so that the C side faces the object to be heated, and in addition, the A side is placed at the F 1 ″ of the crystal rod as shown in Figures 4 and 5. By arranging the plane parallel to the plane consisting of F 1 , most of the light emitted from the A plane, which has the largest amount of light emission, will be incident in a direction almost perpendicular to the cylindrical surface of the melting zone. This is a highly efficient arrangement method.

Of course, its use is not limited to single crystal growth, but may also be used for simple heating.
