摘要： PROBLEM TO BE SOLVED: To provide a water electrolysis system which keeps efficiency of the whole system optimum, by grasping an optimal operating point of an input source to the water electrolysis cell, or equivalently, a maximum output.
SOLUTION: This water electrolysis system has a DC-DC converter capable of converting a high power, installed between a solar battery having high-voltage and low-current characteristics and an electrolysis cell having low-voltage and high-current characteristics. The whole system is connected with a control circuit. The control circuit has a means for detecting the optimal operating point of the solar battery, or equivalently, the maximum power Pm; a means for detecting the input power Pin of the converter; a means for detecting the output power of the converter, or equivalently, the power Pout applied to the electrolysis cell, and a means which can output the output voltage Vout of the DC-DC converter so that the efficiency η of the whole system can be maximized.

摘要： PURPOSE: To remove the influence from uneven light intensity caused by combustion by using the initial peak value of a light-emitting signal to correspond to the initial combustion peak caused by ignition and firing of inflammable air- fuel mixture in a combustion chamber.
CONSTITUTION: Microwaves of a fixed frequency are generated a microwave oscillator 1, while a microwave unit I is provided to detect 3 the received microwaves and convert them into a low frequency signal. Then, a probe II is provided to be composed of a microwave sensor to radiate microwaves in a combustion chamber and receive the reflected waves and a light-sensor to detect the light-emitting state caused by the combustion chamber electrically. Meanwhile, a light signal processing unit 7 is provided to detect 6 the peak of the microwave signal outputted from the microwave unit I and the initial peak value in the light-emitting signal outputted from the light sensor of the probe II in each cycle for calculating 9 the time difference between the peak middle point of the microwave and the time when the light-emitting signal reaches to an intensity of a fixed ratio of the initial peak value. This construction permits to detect the timing of combustion precisely.

摘要： PURPOSE: To simplify a system and to detect precisely the combustion starting time by detecting the combustion starting time based on a microwave signal and a light signal.
CONSTITUTION: A microwave 1 is transferred to a cable Fc through a circulator 2. It is converted into a wave guide mode TE in a coaxial wave guide conversion part, converted into a coaxial mode TEM in the said part, conducted to auxiliary chamber AC, and entered in a main chamber MC. If a piston is not at a resonance position, the microwave is reflected and enters a circulator 2. Then it is separated from a transmission wave, it turns into a low frequency signal owing to a detector, and it is sent to a processing part. A photodiode outputs a spark signal following ignition. The processing part III processes the low frequency signal from the detector 3 at a peak detecting part 15, processes the light signal at a processing part 16, then outputs the time difference between the central peak of the microwve signal and one tenth the peak point of the light signal at a time difference computing part 17, and displays the injection time and angle on a display unit DD1W3.
