I have checked a lot of DICOM Images about CTDI Phantom Type Code Sequence Attribute (0018,9346) Values. I found 2000 times the value: 1)
What do these signs "1)" mean?

You should probably ask the engineer, who performed the studies, or the technician who had installed the machine an did setup of the worksation.
I could only guess and I would take a shot that this sequence means, that "there was a phantom used during the study".
You need to get used to the fact, that DICOM standard is something like a suggestion, not a requirement. For example, when you get a series where 0008,1030 ("Study Description") has value "CTChest", you shouldn't assume that this is a CT of the chest, as it could be any type of the examination.
