    • A method for manufacturing thermal heads comprises providing a substrate having a first surface, a second surface opposite the first surface, heaters disposed on the first surface, and pairs of electrodes disposed on the first surface, the electrodes of each pair of electrodes being disposed in spaced-apart, confronting relation to each other. A driver IC is mounted on each of the electrodes. The driver ICs are then encapsulated with a resin. Grooves are formed in at least one of the first surface and the second surface of the substrate so that the electrodes of each pair of electrodes are disposed symmetrically with respect to one of the grooves. The substrate is then cut along the grooves to form individual thermal heads each having a heater, at least one of the driver ICs for providing a drive signal to drive the heater, and a sealing element formed by the resin for protecting the driver IC.

    • There is provided a control system capable of realizing a highly robust control having a large margin of stability. The ECU of the control system controls the air-fuel ratio of exhaust gases emitted from the first to fourth cylinders. The ECU 2 estimates an estimation value of a detected air-fuel ratio, from a model defining a relation between the estimation value and a plurality of simulation values, and identifies an intake air amount variation coefficient such the estimation value becomes equal to a detected air-fuel ratio. The ECU calculates an air-fuel ratio variation correction coefficient according to the identified air-fuel ratio variation coefficient, on a cylinder-by-cylinder basis, and a learned correction value of the air-fuel ratio variation correction coefficient, on a cylinder-by-cylinder basis, and corrects a basic fuel injection amount by the air-fuel ratio variation correction coefficient and the learned correction value, on a cylinder-by-cylinder basis, to thereby calculate a final fuel injection amount.
    • 提供了能够实现具有大的稳定性的高度鲁棒的控制的控制系统。 控制系统的ECU控制从第一至第四气缸排放的废气的空燃比。 ECU2根据定义了估计值和多个模拟值之间的关系的模型来估计检测到的空燃比的估计值,并且识别出该估计值等于检测到的空气的进气量变化系数 - 燃料比。 ECU根据所识别的空燃比变动系数,在逐缸的基础上计算空燃比变动校正系数和空燃比变动校正系数的学习校正值, 并且通过空燃比变化校正系数和学习校正值在逐个气缸的基础上校正基本燃料喷射量,从而计算最终燃料喷射量。
