Abstract: A utility vehicle includes a stack sensor for detecting whether a stack has occurred in a vehicle, and a controller. When a differential device is in an open state, the controller determines the presence or absence of a stack based on a detection result by the stack sensor. When it is determined that a stack has occurred, the controller activates the brake device to reduce a rotation speed of a stack wheel, which is a wheel idling due to the stack.

Abstract: A utility vehicle includes: a plurality of wheels mounted with low-pressure tires; an output operating element that is operated by a driver and receives an increase/decrease instruction to increase or decrease a driving force; a switching operating element that receives a switching instruction for switching between travel modes; and a controller. The controller has a manual travel mode in which the driving force is controlled in accordance with an amount of operation on the output operating element, and a control travel mode in which the driving force is controlled so as to maintain a travel speed at a target speed that is set within a predetermined speed range, the control travel mode being executed in response to an input on the switching operating element.

Abstract: A utility vehicle includes: an engine; a drive wheel; a power transmission path between the engine and the drive wheel; a clutch that is provided in the power transmission path and configured to disconnect power transmission when an engine rotational speed is lower than an engage rotational speed; an engine rotational speed sensor configured to sense the engine rotational speed; and a controller configured to control an operation of the engine, the controller including an engine brake necessity determination circuitry configured to determine necessity of engine braking, and an engine rotational speed control circuitry configured to control the engine rotational speed, and when the engine brake necessity determination circuitry determines that engine braking is necessary, the engine rotational speed control circuitry is configured to perform automatic engine brake control that increases the engine rotational speed so as to be equal to or higher than the engage rotational speed.

Abstract: The heat transfer sheet according to this invention includes a substrate sheet and a dye carrier layer formed on one surface of said substrate sheet, and is characterized in that the dye included in the dye carrier layer is represented by the following general formula (I): ##STR1## wherein R.sub.1 -R.sub.4 and X each represent a substituent. According to this invention, it is possible to obtain image representations improved in terms of printing density and clearness as well as storability and resistance to discoloring and browning.

Abstract: A heat transfer sheet including a substrate sheet and a dye carrier layer formed on one side of the substrate sheet is characterized in that the dye included in the dye carrier layer is a dye containing chromophores resulting from at least two azo bonds linked together through a non-conjugated linking group.
