Abstract: Damage to a substrate in a substrate processing apparatus is effectively suppressed. The substrate processing apparatus includes a polishing unit polishing a substrate, a cleaning unit cleaning and drying the substrate polished by the polishing unit, and a conveying unit conveying the substrate in the polishing unit and the cleaning unit. The substrate processing apparatus further includes a measuring section 5A measuring a standby time of each substrate for which the substrate stands by in each of the polishing unit, the cleaning unit and the conveying unit, and a determining section 5B comparing the standby time measured by the measuring section 5A and a set time set for each unit independently and determining that an error occurs if the standby time exceeds the set time.

Abstract: A navigational system particularly adapted for use with small open vehicles such as a motorcycle. The navigational system includes a display which displays, in addition to vehicle speed and distance traveled, navigational information as to points along a pre-selected course of travel and the distance and turning direction to reach each successive point. The operator may also insert information about each point, such as observations about the point as the name of the point. The display switches from providing a first display condition that provides the travel information and a second condition that permits the insertion of data into the system. The insertion display is not enabled unless the vehicle is in a standing condition.
