What is the purpose of DB x 1 surrounded by the nomenclature of industrial sewing apparatus hypodermic?

Industrial sewing machine needles are categorized as DB x 1, DC x 27 etc. what is the meaning of DB contained by that? 1 in that? or DC in that? 27 contained by that? what type of needle size system is that? Does this have any nouns with European or American size system?
Answers:
That's a Japanese needle system designation. I do not apprehend where the name comes from, but can put in the picture you that a DBx1 is a round-shanked industrial needle. Same needle is also agreed as:
16x231, 16x257, 1738, 287WH, SY2254 and Canu 14:25

I'd suggest you might as Organ needles, as I believe they originated the DBx etc. designators.

Size (a function of needle blade diameter) is not matching as needle system, which specifies the length to the eye, shank type, etc.
