  • Patent number: 6328829
    Abstract: Hardening is accomplished by heating a longitudinal section of a workpiece such as an odd-shaped bar, and by quenching while constraining the workpiece section in dies. The quenching is executed while the workpiece is pressed in a direction perpendicular to its longitudinal direction by a pressing device which is installed adjacent to the workpiece section constrained in the dies. Warping by quenching can thus be minimized in odd-shaped workpieces, such as an automobile steering rack bar.

    Abstract: In a semiconductor substrate having a surface including a first surface region at a first level, a second surface region at a second level lower than the first level, and a step side region linking the first surface region and the second surface region together, a channel region has a triple structure. Thus, a high electric field is formed in a corner portion between the step side region and the second surface region and in the vicinity thereof. A high electric field is also formed in the first surface region. As a result, the efficiency, with which electrons are injected into a floating gate, is considerably increased.
