When in the time that this is used in specification and claim, word " at least one ", in row of mentioning one or more key elements, be to be understood as at least one key element that means to be selected from any one or more key elements in this row key element, but needn't comprise at least one in each key element of specifically listing in this row key element and not get rid of the combination in any of the key element in this row key element.The key element that this definition also allows to be different from each key element of special identification in this row key element relating in word " at least one " can optionally be presented, relevant or uncorrelated to those key elements of special identification.Like this, as limiting examples, one of " A and B at least " (or, equally, " A or B are one of at least; " or, one of " A and/or B at least " equally) can be: refer in one embodiment at least one, optionally comprise and there is no B (and optionally comprising the key element that is different from B) by more than one A simultaneously; Refer in another embodiment at least one, optionally comprise and there is no A (and optionally comprising the key element that is different from A) by more than one B simultaneously; Another mode of execution middle finger at least one, optionally comprise more than one A, and at least one, optionally comprise more than one B (and optionally comprise other key element); Etc..
In each claim, and in superincumbent specification, all conjunctions such as " comprising ", " comprising ", " carrying ", " having ", " containing ", " relating to ", " holding ", " by ... form " etc. be suitable for being understood as that to be open,, the meaning is to include but not limited to.Only have conjunction " by ... composition " and " substantially by ... form " will be respectively enclosed or semienclosed conjunction.
Each claim should not be interpreted to and be limited to described order or key element, is that meaning unless be declared.Should be understood that, those skilled in the art can carry out the various variations in form and details in the case of not departing from the purport of appended claim and scope.The all mode of executions that fall in purport and the scope of listed each claim and equivalent thereof are all claimed.
