Title: Heat-treatment device
Inventor: SHIRAKAWA HIDEKAZU
IPC: H01L21/027
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To efficiently control the temperature of a heat-treatment board by stopping the heating of the board to fix the actuation of a temperature control means during the period, until the succeeding substrate to be treated is placed on the board after the preceding substrate to be treated is separated from the board. SOLUTION: A control section 120 maintains nearly constant temperature of a heat treatment board 58 by turning on the power supply to a heater H, when the temperature of the board 58 detected by means of a temperature sensor in a state, where the temperature of the board 58 is stabilized after the power supply to the heater H is turned on is lower than a prescribed value, and when the temperature of the board 58 becomes higher than a prescribed value, turning off the power supply to the heater H. After a wafer W placed on the board 58 is heat-treated, the power supply to the heater H is stopped by temporarily stopping the temperature control during the period until the succeeding wafer W is placed on the board 58, after the preceding wafer W has been separated from the board 58.  Therefore, the overheating of the board 58 can be prevented in advance, and the temperature of the board 58 can be controlled efficiently.

Abstract: PROBLEM TO BE SOLVED: To allow the radio communication equipment that conducts automatic frequency control and intermittent reception to be immune to the effect of external disturbance in the case of making communication and to easily lock a reception frequency in the case of an intermittent reception state. SOLUTION: A radio communication signal received by a reception section 3 is synthesized with a reception local oscillation signal from a synthesizer 4 and converted into an intermediate frequency signal, which is fed to a signal processing section 5. The signal processing section 5 processes the signal and provides the signal to a speaker 24 and detects a frequency error of a reference oscillator 8 from the intermediate frequency signal and gives the result to a changeover circuit 20. When the radio communication equipment is in the communication state, a time constant circuit 7A with a large time constant is selected and when the communication equipment is in an intermittent reception state, a time constant circuit 7B with a small time constant is selected.  The frequency of the reference frequency signal of the reference oscillator 8 is corrected based on a frequency error signal given via either of the time constant circuits 7A, 7B.
