    摘要: The timing of spark ignition is set in normal operating conditions at a programed spark advance angle corresponding to the MBT (minimum spark advance for best torque). When knocking of the engine is detected by a vibration sensor, the ignition timing is delayed by a predetermined amount, e.g., 2.DELTA..theta., for each engine cycle that knocking is detected in synchronism with the rotation of the engine. When knocking is not detected, the ignition timing is advanced by another predetermined amount, for each engine cycle that knocking is not detected. e.g., .DELTA..theta.. In this method for controlling the spark timing, the amount of retardation, 2.DELTA..theta., is selected to be larger than the other amount of advance, .DELTA..theta..

    摘要: A three-dimensional modeling apparatus includes a stage, a head, an adjustment mechanism, an ejection command means, and a control means. On the stage, a powder material is accumulated. The head ejects ink to the powder material on the stage. The adjustment mechanism adjusts a relative height of the stage and the head for each predetermined layer thickness so that a three-dimensional object is formed on the stage by the predetermined layer thickness. The ejection command means causes the ink to be ejected from the head so that the powder material is colored a plurality of colors corresponding to multilevel luminance information items in a multivalued image obtained by performing a multivalued processing of luminance with respect to a two-dimensional cross-sectional image data of a modeling target object. The control means controls the adjustment mechanism and the ejection command means so that the multivalued image is drawn for each layer thickness.

    摘要: A three-dimensional modeling apparatus includes a stage, a movement mechanism, first and second supply mechanisms, and a head. To the stage, a modeling material is supplied. The movement mechanism moves the stage in a predetermined direction. The first supply mechanism and the second supply mechanism are disposed along the predetermined direction. The first and second supply mechanisms supply the modeling material onto the stage that is moved by the movement mechanism. The head discharges a liquid to the modeling material on the stage. The liquid is capable of hardening the modeling material supplied from at least one of the first supply mechanism and the second supply mechanism.
