Title: Air-fuel ratio control device having learning function
Inventor: ISHIDA KATSUMI
IPC: F02D41/14
Filed: 1989-12-12
Abstract: PURPOSE:To prevent the occurrence of erroneous learning by determining an accumulating total value of a deviation from a reference value of a feedback control factor responding to an output from an exhaust gas sensor and discriminating the displacing tendency of a learning value through comparison of the accumulating total value with a decision value. CONSTITUTION:Based on an operation state by a detecting means 6, a fundamental fuel amount is determined by a computing means 8, and correction is added by a correction means 12 by means of the learning value of a memory means 10. By means of an output from an exhaust gas sensor 2, feedback control is made on a feed fuel amount by a control means 14 through a fuel excess and deficiency discriminating means 16. In which case, at a given leaning condition period, a computing means 20 determines a deviation amount from the reference value of a feedback control factor. Each time the discriminating result of the discriminating means 16 is inverted, the even number of deviations at a time is accumulated by an accumulating means 21, and the accumulating result is compared with first and second decision values by comparing means 22 and 26. When it exceeds the first decision value, a learning value is regulated by a given amount through a learning value increasing means 24 and when it is below the second decision value, the learning value is regulated by a given amount by a learning value reducing means 28. This constitution prevents the occurrence of erroneous learning.

Filed: 1994-12-26
Abstract: PURPOSE:To accelerate charged particles by a positive ion accelerating tube, and generate a high energy neutral particle beam by making light like a laser beam incident on a high voltage terminal part after a wavelength and intensity are adjusted. CONSTITUTION:When a charged particle having negative charge has optically strong resonance transition, a laser beam having a short wavelength is made incident along the beam axis 8. That is, the laser beam having the short wavelength whose wavelength is adjusted so that a wavelength of light when viewed from the charged particle passing through a high voltage terminal part 5 exactly coincides with the resonance transition possessed by the charged particle, is made incident along the axis 8 from a laser generator 9. In a part 5, since the wavelength of the laser beam oscillated by the generator 9 coincides with the resonance transition possessed by the charged particles, electrons are emitted. Thereby, polarity of the charged particle is converted, and it is accelerated by a positive ion accelerating tube 4, and is emitted through a deriving tube 13. Thereby, various molecule ions or the like composed of plural atoms can be accelerated, and a neutral particle beam having high energy can be generated.

In respect of this temporary point, a straight line which passes through this point and makes the width of line minimum and iTs gradient are obtained. The middle point of the width of line is determined along the obtained straight line of the gradient, and is made the true starting point of the locus of the line drawing. The starting point is moved to a direction perpendicular to the obtained straight line of the gradient, and the moved point is considered to be the temporary point position of the next point. In respect of this point, the true point position is obtained by processing similar to the case of the starting point. Hereinafter, this processing is repeated.
