A container position measuring method using a microwave sensor 31 which emits microwave 35 and receives reflected wave of the microwave 35, wherein a position of a corner portion of a transportation container is measured by reflected wave from the corner portion. The microwave 35 is not influenced by weather and color of a transportation container 18. Therefore it is possible to reliably measure position data of the transportation container. The microwave 35 does not easily receive the influence of weather and color of the transportation container. The present invention provides a position measuring method capable of stably measure position data of the transportation container.

A knock control apparatus of ignition timing control type according to the present invention comprises, as one aspect thereof, a knock control level increasing means for augmenting a knock phenomenon suppressing function, so that, when the knock interval is short, the output characteristic of the integrating means is increased to raise the control level for suppressing the knock generating element in each cylinder of the engine, and that the integrating means output characteristic is invalidated when the condition of the internal combustion engine reaches the normal operating state. The knock control apparatus comprises, as another aspect thereof, a reset pulse generation circuit for resetting the voltage from the above integrator to zero at the interval of more than a predetermined number of times the ignition cycle and in synchronism with the ignition signal.
