Abstract: A cell culturing apparatus and a cell culturing method are disclosed. A rack supporting apparatus includes a loop tracking and a plurality of culturing racks connected one after another in series. Each of the culturing racks accommodates culturing containers therein for cell culturing during their travel on the loop tracking. Each of the racks is accessible, through conveyors, to a container handling station where culture medium is filled in the culturing containers and cell inoculation is carried out. The culturing containers processed in the container handling station are automatically accommodated into the rack by an infeed station for starting cell culturing, and the culturing containers in which cell culturing have been performed in the rack are automatically discharged therefrom by a discharge station.

Abstract: A rotary stock rack in which a plurality of racks having wheels at the underside thereof are connected with one another in endless series by means of connecting links, and the plurality of racks are adapted to reversely travel on an elliptic orbit along the outer periphery of a frame body in which rotary cradles support the racks on semicircular portions of the frame body.

Abstract: Disclosed herein is an industrial robot equipped with an articulated arm unit which includes a first arm, second arm, a holder case and a holder. The basal end portion is pivotally attached to a shoulder shaft, which is formed of a first and second shafts disposed on the same axis and rotatable independently from each other. A differential transmission mechanism is arranged over mutually-opposing end portions of the first and second shafts. First drive means is formed by the first shaft and first coupling means so as to rotate the holder. Second drive means is also formed by the second shaft and second coupling means so as to rotate the holder case. The second drive means is also provided with third coupling means, which is also connected to the differential transmission mechanism, so as to compensatively rotate the holder.
