  • Publication number: 20160264921
    Abstract: It is constituted such that a sterile work can be applied by a worker 29 to cells or the like through a glove 28 provided in an isolator 15. A headset 31 for work outputting a work procedure of the sterile work in voice is prepared for the worker, and an input device 39 for check is prepared for a checker 36. A management device 12 outputs the work procedure of the sterile work this time in voice to the headset for work. When the fact that the worker has normally performed the sterile work this time is checked by the checker, and when the fact is input from the input device for check to the management device, the management device performs the subsequent work procedure. Since the sterile work by the worker 29 can be monitored by the checker 36, a wrong work can be prevented from being performed.

  • Patent number: 9174646
    Abstract: An electric vehicle motor control device controls the transmission of power from an electric motor to driving wheels via an automatic transmission. The electric vehicle motor control device includes a vehicle speed detecting device that detects a vehicle speed of the electric vehicle and a controller. The controller includes a required driving power calculating section that calculates a required driving power of the electric vehicle, and a target motor rotational speed calculating section that calculates a target motor rotational speed. The target motor rotational speed is calculated so that an efficiency of a product of a power consumption rate of the electric motor and a transmission efficiency of the automatic transmission will become a prescribed target efficiency, based on the vehicle speed and the required driving power. The controller controls the electric motor based on the target motor rotational speed.
