    ! 変数 *name* の出力が有効であれば, 
    ! .true. を, そうでなければ .false. を返します. 
    ! 出力が有効であるかどうかは, 出力間隔 *interval_value* の
    ! 正負によって判定されます. 正の場合が有効, 負の場合が無効です. 
    ! *gthstnml* が初期設定されていない場合にも .false. が返ります. 
    ! *name* に関するデータが存在しない場合にも .false. が返ります. 
    !
    ! なお, 与えられた *gthstnml* が HstNmlInfoCreate によって初期設定
    ! されていない場合, プログラムはエラーを発生させます. 
    !
    ! If output of a variable *name* is valid, 
    ! .true. is returned, otherwise .false. is returned. 
    ! Whether output is valid or not is judged with positive or negative 
    ! of *interval_value*. Positive is valid, and negative is invalid. 
    ! When *gthstnml* is not initialized, .false. is returned too. 
    ! When data correspond to *name* is not found, .false. is returned too. 
    ! 
    ! If *gthstnml* is not initialized by "HstNmlInfoCreate" yet, 
    ! error is occurred.
