In a monocrystal producing device using a pulling-down method, a raw material melt 5m is continuously supplied into a crucible 2 to grow a crystal 18 by supplying a powdery raw material 5p onto a premelt plate 3 inside an electric furnace 10 with a powdery raw material supplying device 20 and melting the powdery raw material 5p on the premelt plate 3 to generate the raw material melt 5m, and causing this raw material melt 5m to drop out inside the crucible 2. A dry air is introduced into the powdery raw material 5p inside the powdery raw material tank 6 to prevent moisture of the raw material powder 5p. A transferring tube 9 for transferring the raw material 5m is cooled to prevent the filling in the transferring tube 9 based on melting of the powdery raw material 5p. This makes it possible to produce a monocrystal having a stable chemical composition, a large diameter, and a long size at a low price.

摘要:
A shift register comprising a digital filter samples an input signal inputted from an external terminal based on a clock signal and inputs output signals a to d of the shift register constituting the results of the sampling to a gate circuit also comprising the digital filter. The voltage level of the output signal of the gate circuit makes a transition from an L level to an H level when at least three voltage levels of the output signals a to d are H levels. A sense circuit then detects changes in the voltage level of the gate circuit and outputs a signal instructing for the data outputted from the counter to be stored in the register.
