Abstract: PURPOSE:To prevent melt temperature from fluctuating and grow an epitaxial layer without any dispersion in composition by providing an apparatus for liquid-phase epitaxial growth of a compound containing a volatile metal with an annular groove for storing the metal condensed in a reflux chamber of the aforementioned apparatus and controlling the temperature thereof CONSTITUTION:A compound semiconductor containing a volatile metal such as mercury is grown by liquid-phase epitaxy. In the process, the volatile metal is condensed in a reflux chamber 13 sealed with a lid unit (8a) provided in the upper part of a reaction chamber and an annular groove 24 and stored in the annular groove 24. The stored volatile metal, as necessary, is then heated with a sub-heater 22 installed on the outside of the annular groove 24 and vaporized from the annular groove 24 into the interior of the reaction chamber 2. The vapor pressure thereof is balanced with the vapor pressure of the volatile metal vaporized from the raw material melt in the reaction chamber by temperature control with the heater 22. Thereby, since the vapor pressure of the volatile metal in the whole reaction chamber approaches the equilibrium between the liquid and the vapor phases, the composition of the melt is prevented from fluctuating.

Abstract: PURPOSE: To maintain a predetermined min. spacing by regulating a perforator blade when the positional difference between an aligning mark signal and a perforation signal is larger or smaller than the desired distance between an aligning mark position and a perforating position. CONSTITUTION: When the number of pulses between the signals sent out of a drum switch 144 and a perforator switch 150 is larger than the number of pulses corresponding to the distance (skirt length) between perforating and sealing positions and the skirt length is small, a motor 166 is rotated in an advance direction to increase the number of rotations of a perforator block 82 to a perforator pulley 85. By this constitution, the perforating position is moved so as to go away from the sealing position to reduce the number of pulses between the signals sent out of the drum and perforator switches 144, 150. When the number of pulses coincides with a desired number of pulses, the motor 166 is stopped. The number of pulses between the drum and perforator switches 144, 150 is tracked to be compared with a desired number of pulses to maintain a desired min. skirt length.

Title: Production of composite structure composed of fiber and phenolic resin
Inventor: HOJO TATSUO
IPC: C08G8/00
Filed: 1992-10-02
Abstract: PURPOSE:To produce a composite resin structure excellent in formation and exhibiting a high strength in a high yield by using a fiber/resin component dispersion prepared from an inorganic fiber and a specified phenolic resin according to a specified method. CONSTITUTION:An inorganic fiber (e.g. glass fiber) is initially dispersed in a water containing a polyethylene oxide-based dispersant at a neutral pH and a polyacrylamide-based dispersant is subsequently added thereto to disperse it more uniformly. Further, a powdery thermosetting phenolic resin having 0.1 to 150mum average particle diameter is added and uniformly dispersed in the dispersion system at an arbitrary stage, e.g. before dispersing the inorganic fiber or after adding the polyethylene oxide-based dispersant. The resultant dispersion containing the inorganic fiber and the phenolic resin is then allowed to stand for a prescribed time so as to coagulate the phenolic resin by an effect of the polyethylene oxide-based dispersant. The fiber/resin component dispersion is subsequently poured into a perforated substrate and the solvent component is removed, thus producing the objective structure.
