Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To adjust the distortion of the flatness of the product of wavelength- transmissivity characteristics of a light wavelength multiplexing and demultiplexing circuit in a signal light transmission band and how the flatness is distorted according to individual examples. SOLUTION: Light wavelength multiplexing and demultiplexing parts are adjusted as to the position of transmission center wavelengths corresponding to the same wavelength channel to adjust the total wavelength-transmissivity characteristics of respective wavelength channels in the wavelength multiplexing and demultiplexing of the group of the light wavelength multiplexing and demultiplexing parts. Consequently, the distortion of the flatness of the total and effective wavelength-transmissivity characteristics which are different by individual examples can be adjusted with wavelength-transmissivity characteristics of other light wavelength multiplexing and demultiplexing circuits used on an optical network corresponding to the individual examples.

Abstract: PURPOSE:To prevent water from being fed to a heat exchanger and further prevent heat from being taken by a heat exchanger during a heating and cooking operation by a method wherein a water valve is arranged in a water feeding passage and the water valve is closed by closing a cooking switch. CONSTITUTION:A water valve 24 is arranged in a water supplying passage 18, and a circuit having a coil 24a for the water valve 24 is provided with a switch 16b to be opened by closing the cooking switch 16 in such a way as the water valve 24 is closed under a closed state of the cooking switch 16. In addition, a changing-over shutter 25 is provided so as to cause the hot air in a chamber 5 to be freely selected for a cooking chamber 3 and a heat exchanger 21. As a cooking switch 16 is closed, the coil 13a is energized to cause an electromagnetic gas valve 13 to be opened. Fuel gas is supplied to a gas burner 6 and then a combustion at the gas burner 6 is started. The hot air within the combustion chamber 5 generated by combustion is guided into the heating and cooking chamber 3 and the heating and cooking operation can be attained. At this time, since the water valve 24 arranged within the water supplying passage 18 is closed, the supplied water is not generated in the water supplying passage 18 and heat is not taken of the heat exchanger 21.

IPC: F02D9/02
Filed: 1987-09-11
Abstract: PURPOSE:To reduce the consumption power of a drive motor, by providing a means which limits the input current of a drive motor according to the number of revolutions of an engine. CONSTITUTION:With an accelerator pedal 9 stepped on, a second throttle valve 4 is rotated according to a step on amount. By means of an output signal from an accel sensor 19, detecting a step on amount, a computing control part 21 actuates an electronic control actuator 13 to rotate a first throttle valve 2, and control is effected so that the opening of the throttle valve is adjusted to a predetermined value. In which case, when the number of revolutions of an engine is low, even if the accelerator pedal 9 is stepped on to a fully opening state, the throttle valve is not opened to full capacity, and control is made so that the opening of the throttle valve is limited to a value at which an intake air amount responding to the number of revolutions of an engine is saturated. Since the rotation angle of the first throttle valve 2 may be low, this constitution enables limitation of the input current of a drive motor 131 to a low value.
