摘要： PURPOSE: To reduce the degree of risk at a time when a substrate holder is extracted to the outside and overhauled, and to inhibit the temperature rise of a bearing section and improve reliability by supporting a protective cover while using a liquid-nitrogen shroud as a base and leaving the projective cover in a growth chamber when the substrate holder is extracted from the growth chamber.
CONSTITUTION: Substrate holders 3 are protected from a contamination by molecular beams by covering the substrate holders 3, and a protective cover 24 to which a window 25 is formed is mounted directly to a section facing the surface of a susceptor 5 while employing a liquid-nitrogen shroud 4 as a base. Accordinly, when the substrate holders 3 get trouble and are extracted outside a growth chamber, the protective cover 24 is left in the growth chamber, and only the substrate holders not contaminated by noxious molecular beams are pulled out, thus reducing the degree of risk on overhauling and correction. Since the surface temperature of the protective cover 24 can be kept approximately at the temperature of liquid nitrogen, heat in the protective cover 24 can be cooled, thus inhibiting the temperature rise of a bearing 20, then improving reliability.

摘要翻译：目的：为了降低将衬底保持器抽出到外部进行大修时的风险程度，并且通过在使用液氮护罩作为保护罩的同时通过支撑保护罩来抑制轴承部的温度升高来提高可靠性并且当衬底保持器从生长室中取出时，将投影盖留在生长室中。构成：通过覆盖基板保持件3来防止基板保持器3受到分子束的污染，并且将形成有窗口25的保护盖24直接安装在面向基座5的表面的部分上，氮气护罩4为基础。一方面，当衬底保持器3产生故障并且在生长室外部被抽出时，保护盖24被留在生长室中，并且只有没有被有害分子束污染的衬底保持器被拉出，从而降低了风险的程度大修和纠正。由于保护盖24的表面温度大致保持在液氮的温度，所以能够冷却保护罩24的热量，能够抑制轴承20的温度上升，提高可靠性。

摘要： PURPOSE:To reduce the escape of heat due to heat transfer from a heater base at a high temperature, to prevent the heat generation of a heater lead wire on the inside of a fixed shaft and to lower the temperature of a bearing section by working a strut for the heater base as the heater lead wire in combination and extending the lead wire up to the side end section of the bearing for the fixed shaft. CONSTITUTION:Heat from a heater 8 at a high temperature or a heater base 9 is transmitted over bearings 4 through a current introducing terminal plate 13, a holding plate 6 and a fixed shaft 3 through struts 12 functioning as heater leads in combination. The struts 12 functioning as the heater leads in combination generate large thermal resistance because length thereof is extremely long, and a temperature sufficiently drops in the current introducing terminal 13 section. Since the thickness of the struts 12 functioning as the heater leads in combination is sufficiently thick, heat generation in the sections can be ignored approximately, thus resulting in no heating from an inner surface of the fixed shaft 3. Accordingly, the temperature of the bearings 4 is lowered remarkably.

摘要： PURPOSE:To obtain a thermal head which enables the radiation of the excessive heat after printing so as to improve the quality of printing, by providing a cooling plate at a position of contact with heat-sensitive paper or a film layer on the surface of the thermal head which forms a heating resistor. CONSTITUTION:A cooling member 10 is provided in a part of a protection layer 2 other than a heating part 1 which corresponds to a heating resistor 4. Although the heat resistor 4 turns cool when the thermal head moves to a place to be printed subsequently, the heat of ink is not fully absorbed by recording paper 9 and remains in liquid-state ink 8a. When the thermal head reaches the position of the subsequent printing, the liquid-state ink left at the position at which the printing is already ended contacts with the cooling member 10 and is congealed rapidly (8b). In a system in which heat-sensitive paper is used, excessive heat accumulated in this paper can be absorbed.

摘要： PURPOSE:To detect easily the position of a face to be measured, by demultiplexing an electromagnetic wave from an object whose temperature should be measured, into its spectral components by a mirror just before an optical fiber for infrared transmission, and leading them to the optical fiber for infrared transmission. CONSTITUTION:In a measuring device, the electromagnetic wave from a face 1 to be measured are received by an objective 3' and are transmitted to a dichroic mirror 9. Infrared rays in the electromagnetic wave are transmitted through the dichroic mirror 9 and are transmitted to an end face 2a of the optical fiber. Infrared rays are propagated in an optical fiber 2 for infrared transmission and are radiated from its end part 2 and are condensed by a condenser lens 4 and are transmitted to a detector in a detecting device 5. By this constitution, visible rays which are not used in the conventional method are used to detect the position and focusing it easily.
