Abstract: A motor has built therein a brake for stopping the rotation of the motor and a brake controlling circuit for controlling the brake. The motor is further provided with a bypass circuit for supplying an electric power directly to the brake and a terminal for connecting a power source to the bypass circuit. When the brake controlling circuit develops a fault, the brake is directly released by an external power source.

Abstract: For a combination of a first movable body adaptive for an automatic motion to provide an equivalent service to a required service, and a second movable body capable of exercising a voluntary motion and to cooperate with the first movable body to provide the voluntary motion as one of assistance and teaching to the first movable body to sophisticate the automatic motion, there are provided a first controller operative in a first mode for controlling the first moving body to exercise the automatic motion and in a second mode for adapting the first movable body to cooperate with the second movable body so that the automatic motion is sophisticated to be capable of achieving an equivalent service to the required service in a sophisticated manner, and a second controller for selecting one of the first and second modes.

Abstract: In an inking apparatus for use in a printing press, an ink pan located below a plate cylinder is separated into a first part which accommodates a furnisher roll for furnishing ink and a second part which receives contaminated ink containing foreign substance scraped off a doctor blade. In order to prevent the ink within the second part from flowing directly into the first part, partitions are provided, or alternatively the second part is positioned lower than the first part, or alternatively the first part and the second part are comprised of two separate receptacles. The supply of ink to the plate cylinder may be carried out by any suitable means other than the furnisher roll. The ink pan may be configured in the form of an exclusive receptacle adapted to receive only the contaminated ink containing foreign substance scraped off the doctor blade, the supply of ink to the plate cylinder being effected without passing through the ink pan.
