  • Publication number: 20200098611
    Abstract: A second substrate transportation mechanism is generally set to transport a substrate from a substrate buffer unit to a FOUP placed on an opener. However, if a predetermined condition is satisfied, the second substrate transportation mechanism transports a substrate from the FOUP to the substrate buffer unit. That is, the second substrate transportation mechanism performs an operation different from an ordinary substrate transportation operation. Accordingly, a FOUP transportation mechanism can leave a specific FOUP at a placement position (opener) of the specific FOUP from when all the substrates are taken from the specific FOUP to when all the treated substrates are accommodated in the specific FOUP. Thus, the FOUP transportation mechanism can transport FOUPs except for the specific FOUP so that FOUP transportation efficiency can be enhanced.

  • Publication number: 20200098612
    Abstract: Each of first and second substrate transportation mechanisms transports a substrate for a FOUP placed not on, for example, each of two openers disposed laterally but on, for example, each of two openers disposed in an upward/downward direction. Thus, even if the number of openers increases, the substrate is transported not by sliding a hand capable of moving forward and backward, but by lifting, lowering, and rotating the hand. Thus, transportation of the substrate can be simplified. Accordingly, standby time of substrate transportation can be reduced, and a decrease in substrate transportation efficiency can be prevented.

  • Publication number: 20190299766
    Abstract: A vehicular control system for reducing shocks by inhibiting switching operation of a dog clutch when drive force cannot be assisted by an engine. A controller determines that an increase in the drive force by the engine is restricted. In a case that an increase in the drive force is not restricted when launching the vehicle, the controller establishes a first gear stage in the transmission to launch the vehicle, and shift to the second gear stage upon satisfaction of a predetermined condition during propulsion while increasing the drive force. In a case that an increase in the drive force is restricted when launching the vehicle, the controller establishes a second gear stage in the transmission to launch the vehicle.

  • Patent number: 9976604
    Abstract: A translational force Fh to one side in a rotational axis direction is caused to act from a hydraulic piston to a sleeve when an engaged stage between an engagement tooth and an engaged tooth is maintained, so that translation of the sleeve to the other side in the rotational axis direction and consequent disengagement of the engagement tooth and the engaged tooth can be prevented. Therefore, the engaged state between the engagement member and the engaged member can be stably maintained regardless of the condition of the torque acting from the drive source to the engagement member.
