  • Patent number: 11268614
    Abstract: A working vehicle includes a traveling clutch to be switched between an engaging state and a disengaging state, a brake to brake the traveling device according to an operation of a brake operator, and a controller to perform a braking control to perform the braking, and an auto-switching controller to switch the traveling clutch from the engaging state to the disengaging state. The controller performs a first processing to switch the traveling clutch from the engaging state to the disengaging state when the brake operator is operated in a case where the auto-switching control is valid and a vehicle speed is less than a threshold, and a second processing to prevent the traveling clutch from being switched from the engaging state to the disengaging state even when the brake operator is operated in a case where the vehicle speed is equal to or higher than the threshold.

  • Patent number: 9004256
    Abstract: A temporary storage in a medium storing device carries out ON/OFF monitoring of a jam sensor between a winding start position of a drum and a clamp point of a delivering roller. Accordingly, when bills are rewound in the reset operation, even when a relationship between a pulse count and a bill position becomes different from actual one, it is possible to detect, without using a pulse count, a jam between the winding start position and the clamp point. It is possible to more securely detect the abnormality in bill storing in comparison with the prior art.

  • Publication number: 20080268381
    Abstract: A pattern forming method includes forming a resist film on a target film to be processed, which is formed on a substrate; and forming a basic pattern part in the resist film by multiple exposure using photomasks, wherein each exposure process is performed at an amount of exposure smaller than a threshold assigned to the resist film; and the resist film is developed after the total sum of the amounts of exposure through a plurality of exposure processes exceeds the threshold, so that the basic pattern part including a hole shape, which corresponds to each area where the total amount of exposure through the exposure processes via the photomasks exceeds the threshold, is formed in the resist film. The method also includes performing etching via the basic pattern part so as to form a desired pattern in the target film.
