Title: Cooking device
Inventor: WAKI MAKIKO
IPC: F24C15/20
Filed: 1989-11-15
Abstract: PURPOSE:To improve a complete broiling performance by a method wherein heat-resistant minute film containing oxidization catalyst is coated in a housing and at the same time a part of substrate material forming the housing can be removed and further a lower heater may perform a direct heating within the housing. CONSTITUTION:An inner wall 1 of an oven type range is coated with a heat-resistant film 2. When a cooked item 6 mounted in a cooking net 9 is heated through an electrical energization of an upper heating heater 3, a large amount of smoke is generated and the smoke passes through a discharging hole 7 and a discharging passage 4 and is discharged out of a discharging hole 8. The smoke while passing through the discharging passage 4, the smoke is purified by a catalyst 5 heated by a surplus heat of the heating heater 3. When the cooked item generating a large amount of oil is to be cooked, a bottom surface part 10 of the inner wall of the housing is removed. Then, a cooking is carried out. However, the oil dripped from the cooked item is absorbed in a catalyst 11. Upon completion of the cooking operation, the cooked item 6 is taken out and the heating heater 3 and a broiling lower heater 2 are electrically energized. However, since the broiling lower heater 12 may heat directly the interior of the heating chamber 13 without passing through the substrate material 10, the heat-resistant film 2 shows a more fast increasing temperature and then the oil contamination adhered onto the heat-resistant film 2 is rapidly burned out.

Abstract: PURPOSE:To prevent the generation of a switch noise and a skew noise in a demodulated signal accompanying the switching of the rotating head without damaging the fidelity of reproduction by digital/analog converting the output of a switch to alternately select the outputs of the first and second delay devices. CONSTITUTION:Signals from two rotating heads 1a and 1b are amplified, converted into digital signals in analog/digital converters 11a and 11b without being switched, FM demodulated through band-pass filters 12a-12d, and then further switched through low-pass filters 14a-14d and delay devices 15a-15d, and made into analog signals in digital/analog converters 18a and 18b. Consequently, the switch noise accompanying the switching of the heads never occurs up to the output signals of the delay devices 15a-15d, and the output digital signals of two delay devices 15a-15d and 15e can be switched at digital data intervals in switches 17a and 17b by setting the interval between digital data. Thus, the generation of the switch noise and the skew noise can be prevented.
