An immersion treatment method with which a vehicle body horizontally immersed in liquid is taken out in a tilted position. The vehicle body is taken out of the liquid at high speed in a tilted position. Foreign matter is separated from the vehicle body and removed together with the liquid.

Method and device for immersion treatment of vehicle

When a user inputs a first extraction condition and a second extraction condition, a first data group is extracted from data registered in a database based on the first extraction condition, and a second data group is extracted from the database based on the second extraction condition. Then, common data that is data that belongs to both the first data group and the second data group is extracted. Finally, information about the common data and other data, which is data in the second data group other than the common data, is displayed in a distinguishable manner.

Method of and apparatus for distributing data, and computer program

This invention enables one, or both, or none of position servo control and position lock control of a galvanomirror, to control a read beam to an optimum position under any of on-track state, seek state, position setting state after the completion of a seek operation, and positional deviation existing state between a write beam and the read beam. The invention locks the position of the galvanomirror when a unit is energized or retried, reads a galvanomirror position signal provided at this moment, finds an offset signal for zeroing the galvanomirror position signal, and adds the offset to the position locked galvanomirror during a seek operation with the write beam, thereby removing an offset of the galvanomirror position signal. The invention determines that the galvanomirror has been abnormally deflected due to a malfunction of a tracking control servo system, upon detecting an abnormality that a tracking error signal used for the tracking control of the read beam exceeds a threshold value and an abnormality that a galvanomirror position signal used for locking the galvanomirror at a central position exceeds a threshold value. The invention removes an offset by adding the galvanomirror position signal to the tracking error signal of the read beam. It is possible to add a lens position signal as well to remove the offset.
