摘要： In continuous casting of steel, the invention is able to accurately detect a crater end only from a value measured by a sensor without needing calibration based on the slab rivet method, etc. An ultrasonic shear wave sensor 6, 8 for transmitting an ultrasonic shear wave to a cast product 1 and receiving it and an ultrasonic longitudinal wave sensor 7, 9 for transmitting an ultrasonic longitudinal wave to the cast product and receiving it are installed at the same position in a continuous casting machine or at two positions apart in a casting direction but at the same position in a transverse direction of the cast product. From variations of an ultrasonic signal received by the ultrasonic shear wave sensor, it is detected that a crater end 4 of the cast product is matched with the installed position of the ultrasonic shear wave sensor. A calculation formula for determining the crater end from a propagation time of an ultrasonic longitudinal wave signal is calibrated such that the crater end computed from the propagation time of the ultrasonic longitudinal wave signal at that time is matched with the installed position of the ultrasonic shear wave sensor. After the calibration, the crater end is determined from the propagation time of the ultrasonic longitudinal wave signal based on the calibrated calculation formula.

摘要： A projection is formed on the outer circumference of an annular member and a stopping member is attached to a cylinder head supporting a camshaft thereon. A side surface of the projection comes into contact with a side surface of the stopping member to restrain a decompression cam from turning when the camshaft rotates in the normal direction. The stopping member does not apply any pressure to the annular member in a radial direction and the annular member does not exert any force on the camshaft. Consequently, frictional resistance against the rotation of the camshaft can be reduced and a loss in the output of the engine can be suppressed.
摘要翻译：在环状构件的外周形成突起，并且止动构件安装在其上支撑凸轮轴的气缸盖上。当凸轮轴沿正常方向旋转时，突起的侧表面与止动构件的侧表面接触以约束减压凸轮转动。止动构件在径向方向上不对环形构件施加任何压力，并且环形构件在凸轮轴上不施加任何作用力。因此，可以减小对凸轮轴的旋转的摩擦阻力，并且可以抑制发动机的输出的损失。
