摘要： A delay-time variable filter delays an input signal by a desired time according to a control signal from a control input node and outputs the delayed input signal, and a positive feedback loop circuit changes the output signal (sinusoidal wave signal) from this filter, and provides a positive feedback of the binary pulse signal to the input side of the filter at a desired level for carrying out an oscillation. This positive feedback loop circuit includes a circuit for changing the signal into a binary signal and providing a positive feedback of the binary signal to the input of the filter by limiting the signal at a desired amplitude. As the delay-time variable filter, a quartic Butterworth low-pass filter is used, for example. As the positive feedback loop circuit, there is used a voltage comparator circuit that changes an input signal into a binary signal and outputs a pulse signal of a desired amplitude.

摘要： A wheelchair T is driven by hybrid control of a fuel cell 3 and a rechargeable battery 5. The wheelchair is driven by a motor M to which electric power is supplied from the fuel cell 3 and the rechargeable battery 5. Electric power is supplied to the motor by hydraulic control based on load fluctuations corresponding to the travel conditions of the wheelchair T. The electric energy generated by the fuel cell 3 is kept at a constant level, and the energy of the lithium-ion battery 5 is additionally used when a high load is applied to the motor such as when the wheelchair is ascending a slope. When excess energy is generated by the fuel cell 3, the lithium-ion battery 5 is charged with the excess energy, thereby minimizing the possibility of exhaustion of the lithium-ion battery 5 so that the wheelchair can travel a long distance. By using a rechargeable battery that is resistant to load fluctuations, the wheelchair can be driven smoothly. By keeping the output of the fuel cell to a constant level, it is possible to prolong its life span. By charging the rechargeable battery with constant electric energy, the load on the rechargeable battery during charging is small, so that the life span of the rechargeable battery can be prolonged too.
