    • PURPOSE: To provide a structure capable of preventing a fine setting at fat contained in a food to be cooked even if a user applies an aluminum foil at a dew receiving pan. CONSTITUTION: A gas burner 2 is installed at an upper part of a chamber 1, a dew receiving pan 3 is arranged at a bottom part of the heating chamber 1, a grid net 4 placed on the pan is provided and a temperature sensing sensor 7 is placed at the bottom surface of the heating chamber 1. The bottom surface of the dew receiving pan 3 is provided with a projected plate 9. If an aluminum foil 10 is tried to be placed at the dew receiving pan 3 with this configuration, the foil is broken by the projected plate 9 so as to expose the projected plate 9 and the bottom surface of the dew receiving pan 3. Thus, radiation heat of the gas burner 2 is absorbed either the projected plate 9 or the bottom part of the dew receiving pan 3 to cause a temperature near the bottom part to be increased. Thus, since this temperature can be detected by the temperature sensing sensor 7, a solenoid valve 6 is opened or closed with a control circuit 8 so as to control the gas burner 2. As a result, it is possible to prevent a fire setting at fat contained in food to be cooked.

    • PURPOSE:To exactly grasp the utilizing conditions of a service function by storing the utilization states of the service function, obtaining them as picture display and hard copy, confirming and collecting them outside through the line. CONSTITUTION:When an operator utilizes the service function through a telephone set 12 with display device, the relevant service function is read from a service function storage device 16 and executed by a central processing unit 15 inside a main unit 11. Further, a service function utilization history storage device 17 stores the utilized service function, the number of times of utilization and utilization history information for each telephone set (the telephone set 12 with display device) which performs the utilizing operation of the service function. After this storage, the utilization history information is read from the service function utilization history storage device 17 and displayed on the screen of a display part 12a of the telephone set 12 with display device as characters.
