Title: Contamination learning control device of throttle valve
Inventor: HOSOYA HAJIME
IPC: F02D41/18
Filed: 1995-02-02
Abstract: PURPOSE: To avoid influence of contamination of a throttle valve so as to improve performance of every kind by learning-correcting the atmospheric pressure estimated by an atmospheric pressure estimating means to agree with the atmospheric pressure estimated when a throttle valve opening is a large value. CONSTITUTION: High reliability estimation is added to a volume intake air quantity detected by an air flow meter corresponding to a throttle valve opening detected by a throttle sensor 10 due to the contamination of a throttle valve 4. The relationship between a throttle valve opening equivalent value and its related value is learning-corrected to eliminate a slippage of an atmospheric pressure estimated value in a throttle valve opening area. The opening characteristic of the throttle valve may be subjected to learning correction instead of learning correction for the volume air quantity of a low opening area of the throttle valve 4. Accordingly, the correction amount of fuel injection amount at the time of transient operation can be set with high accuracy according to a change rate of a throttle valve opening or the like so as to improve the operating performance of an engine.

Inventor: KATSURA YOSHIHIKO
IPC: H04Q11/04
Filed: 1984-01-31
Abstract: PURPOSE:To make an insertion attenuation between a subscriber circuit and a trunk circuit independent of a frequency by making a termination impedance of the subscriber circuit and that of the trunk circuit of a digital exchange equal to or nearly identical to each other. CONSTITUTION:The attenuation distortion characteristic F I II is expressed in Equation I when the termination impedances 201, 202 of the subscriber circuit and the termination impedances 204, 205 of the trunk line trunk circuit are made coincident with an impedance ZII of the trunk line side including the impedance of the trunk link trunk circuit. In adjusting impedances ZBi, ZBii so as to make balanced connection networks X I and XII zero, the characteristic F I II is expressed in Equation II. Thus, even when transfer functions Hsi, HRii are simple constants, the absolute value of the characteristic F I II is independent of the frequency. The attenuation distortion toward the subscriber circuit from the trunk line trunk circuit is similar. In Equations above, HRi, HSi, HRii, HSii are transfer functions of amplifiers 207, 208, 209 and 210.

Abstract: PURPOSE:To obtain a multiplier with few errors by converting two input voltages into two differences in current and then by controlling the magnitude of a current flowing to a conversion part corresponding to one input voltage. CONSTITUTION:When currents flowing to constant current sources CC1 and CC2 of conversion part MX are equalized, a difference between currents flowing through transistors TrQ3 and TrQ4 is in proportion to the value of input voltage Vx. In conversion part MY, a constant current circuit is composed of Trs Q18-Q20, currents are flowed through TrQ9, Q12, and Q10, Q12 according to the positive and negative of input voltage VY to keep a difference between those currents in proportion to VY, and its value is minimized by controlling as much as possible. Currents converted by conversion parts MX and MY are converted by conversion parts MI so that a difference between currents flowing through TrQ5, Q7, and TrQ6, Q8 will be in proportion to the product of input voltages VX and VY, and further converted into a voltage by TrQ13-Q17 in proportion to the product of input voltages VX and VY before being outputted to output eout. Since conversion part MY exercises control to minimize the current, a multiplier can be obtained which has a less influence of the offset value of Trs.
