Note on the Deformed Boson Scheme in Four Kinds of Boson Operators
  The deformed boson scheme in four kinds of boson operators, which was recently proposed by the present authors, is supplemented by the T-type deformation closely related with the su(1,1)-algebra. Two subjects are discussed in relation to the S-type deformation closely related with the su(2)-algebra.
