IPC: F27B17/00
Filed: 1989-08-30
Abstract: PURPOSE:To make it possible to maintain the temperature of a core tube uniformly by heating reacting gas with a reacting-gas heating device before the reacting gas used in a diffusing furnace is transferred into the core tube. CONSTITUTION:Reacting gas is mixed in a reacting-gas mixing device 1. The reacting gas has the temperature in the vicinity of room temperature or the temperature lower than the room temperature. The reacting gas under this state is transferred into a heating chamber 8 of a reacting-gas heating device 9 through a pipe.

The heating chamber 8 is heated to the vicinity of the preset temperature of a diffusing furnace with a heater 4. In this operation, the reacting gas whose temperature is in the vicinity of the room temperature at the time of transfer into the heating chamber 8 is heated to the temperature close to the preset temperature of the diffusing furnace during the passage through the heating chamber 8. The reacting gas is transferred into a core tube 6. Thus the temperature of the core tube becomes uniform.

Abstract: PURPOSE:To ensure a satisfactory clamping action regardless of the level of an input signal and also fixing the clamping level at a constant value, by providing charging and discharging circuits at the output and input signal terminal sides respectively of a capacitor connected in series between the input and output signal terminals. CONSTITUTION:In a clamping mode a clamp pulse input terminal 3 is set at a low level and a transistor (TR) 9 is cut off. A TR7 drives with a constant current the common emitter of differential amplifiers TR5 and TR6. TR3 and TR4 set the potential of a point A, i.e., the base of the TR6 at a reference potential Vc to be clamped. When this level Vc is lower than the base potential of the TR5, i.e., the output voltage Vo, the TR6 is cut off with the TR5 turned on. The electric charge of a capacitor C is discharged by the collector current of the TR5, and both base and emitter potensials of a TR2 are reduced to satisfy Vo= Vc. While the TR6 and TR5 are turned on and off respectively with Vo<Vc. Then a current is supplied from a TR3 to charge the capacitor C, and both potentials of the base and the emitter of the TR2 build up to satisfy Vo=Vc.
