Abstract: In the mobile radio communication system where the UMTS and an another system coexist an idle slot for observing the frequency component of another system is inserted in one superframe of UMTS. The duration of this idle slot is at most half of the duration of one frame that form the superframe and it is inserted at an interval of a specified number of frames. Therefore, the frequency component of the another system can be observed securely from the UMTS. Further, deterioration of interleaving performance of the compressed mode frames during such observation can be suppressed.

Abstract: To form a thick coating by a discharge surface treatment, a voltage between an electrode and a workpiece during a discharge is detected, and it is determined that a discharge surface treatment state is abnormal if it is detected that the voltage is reduced. With this arrangement, it is possible to accurately detect an unstable phenomenon in the discharge surface treatment, and take appropriate measures before a state of the coating and a state of the electrode are worsened due to the unstable phenomenon. By discriminating a stability of the discharge surface treatment, the coating and the electrode are prevented from being damaged.

The target light amount is set such that a relation between the target light amount R and an amount of light Q at a change point that is at the lowest luminance in an input-output characteristic of the image sensor satisfies R<Q.
