Title: Heat treatment device for substrate and temperature compensating ring
Inventor: NISHIHARA HIDEO
IPC: H01L21/205
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a heat treatment device for a substrate, which can evenly treat the substrate over the whole surface by reducing the temperature difference between a temperature compensating ring and the substrate at the time of heat treatment. SOLUTION: A temperature compensating ring 11 compensates the temperature of a substrate W during heat treatment by surrounding the outer periphery of the main surface of the substrate W. Such a material that has a nearly equal characteristic value to that of the substrate W is used for the ring 11, with the characteristic value of a material being defined as the quotient when the specific heat is divided by the emissivity. Therefore, the temperatures of the heated substrate W and ring 11 become closer to each other. Therefore, the temperature difference between the substrate W and ring 11 can be reduced and the substrate W can be treated evenly over the whole surface when the substrate W is heat-treated.

Title: S/n improving device for communication line
Inventor: NAKA TATSUJI
IPC: H04B15/00
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To sufficiently amplify only a signal component with an amplifier and to ensure a sufficient S/N even when noise cannot sufficiently be reduced even with a shielded communication wire, a sufficient communication level cannot be amplified due to restriction in the communication line and a transmitter-receiver, and a frequency of the noise is very close to a frequency of a signal. SOLUTION: When a transmission level discrimination device 19 detects a signal of a prescribed transmission level or over, a 1st switch 24 is closed. Thus, signals outputted from MODEMs 4, 7 are amplified by an amplifier 14 to enhance their levels and the result is sent to a communication line 3. On the other hand, when the transmission level discrimination device 19 cannot detect a signal of a prescribed transmission level, the 1st switch 24 is opened and a 2nd switch 25 is closed. Thus, a signal received from the communication line 3 is attenuated by an attenuator 18 and the attenuated signal is given to the MODEMs 4, 7. Thus, the level of the reception signal is decreased down to a reception level of the MODEMs 4, 7 and the noise level is suppressed less than the reception level of the MODEMs 4, 7.
