The process gas is sent into a heater 13 and thereafter devices. The process gas is heated in the heater 13. When the process gas stays in a recombiner 14, hydrogen and oxygen in the process gas undergo bonding reaction and steam is formed. The high temperature process gas after the reaction is cooled in a cooler 15 and returned into a suppression chamber 18. This process is repeated continuously, and the concentration of the combustible gas in the dry well 1 and the suppression chamber 18 is reduced.

CONSTITUTION:The paper where the test mark is printed by a printer is held on a table 6 and both corners of the front edges of the paper are detected with the camera eye 8 so as to measure the tilt angle. Then, the test mark which becomes the measurement start point and the test mark which becomes the measurement end part are detected with the camera eye 8 to measure the positions of the test marks on the start point and the end point. Thus, the position of the corner and the tilt angle of the paper on the table 6 are detected first. Then, the approximate position of the test mark which is going to be detected next can be calculated. By moving the camera eye 8 quickly, the mark is rapidly detected and a position measuring action can be quickly performed. Since measuring accuracy does not depend on positioning accuracy of the paper, the measurement with high accuracy can be accomplished by using position measuring scales 23 and 24.

Title: Liquid phase growth method
Inventor: SAKATA MASAAKI
IPC: C30B19/00
Filed: 1983-12-23
Abstract: PURPOSE:To enable to control independently thicknesses and the growth speeds of respective liquid phase growth layers by a method wherein the load of a solute is reduced as to be saturated at a temperature comparatively near to a growth temperature to check the increase of the degree of supersaturation at the lower part of a molten liquid even in a time period not coming in contact with a substrate.

Accordingly, initial crystallizability is inferior, and at multilayer growth, crystallizability of an interface is inferior. When an epitaxial layer is provided on a semiconductor crystal from the molted liquid by setting at least the load of the solute to the solvent of the molten liquid to be used at the initial period of growth as to be saturated at the temperature higher by about 2.5-3.5 deg.C than the growth temperature, precise control of crystallizability and thickness of the growth layer can be attained, and extremely effective for manufacture of a high-performance element according to the multilayer construction of thin growth layers.
