Abstract: A vehicle display control device includes: a map information acquisition unit that acquires map data around a vehicle; and an item display unit that overlaps a virtual item on a predetermined travel road on the map data and that displays the virtual item in a display area in a vehicle cabin. The item display unit overlaps and displays the virtual item on the map data, thereby guiding a driver of the vehicle toward the travel road on which the virtual item is displayed.

Abstract: A maintenance information management device includes an information registration unit configured to register vehicle identification information and maintenance information in a memory for each vehicle, an information update unit configured to update the maintenance information after the maintenance of the vehicle by adding maintenance contents to the maintenance information registered in the memory, and an information providing unit configured to provide the maintenance information when a provision request for the maintenance information is accepted.

Abstract: A bulldozer includes: a travel manipulation lever that receives a manipulation of an operator and outputs a travel command to allow a travel device to travel or to stop the travel device; a fuel adjustment dial that sets a rotation speed of an engine; a seating sensor that outputs a seating signal indicating a sensed result of whether or not the operator is seated in an operator seat; a monitor that performs notification to the operator; and a controller. When the travel command to allow the travel device to travel is issued from the travel manipulation lever, a set value of the rotation speed of the engine is lower than or equal to a predetermined value, and the operator is not seated in the operator seat, the controller causes the monitor to perform the notification.

Abstract: A heating furnace tube, a method of using the same and a method of manufacturing the same which have been developed with a view to eliminating inconveniences occurring when a carbon-containing fluid is made to flow in the heating furnace tube. The heating furnace tube which comprises a rare earth oxide particle distributed iron alloy containing 17-26 wt. % of Cr and 2-6 wt. % of Al. The method of manufacturing this heating furnace tube which comprises the steps of forming or inserting an insert metal on or into at least one of a joint end portion of one heating furnace tube element and that of the other heating furnace tube element, bringing these two joint end portions into pressure contact with each other directly or via an intermediate member, and diffusion welding the two heating furnace tube elements to each other by heating the insert metal.

Abstract: A drive apparatus uses a plurality of actuators such as multilayer type piezoelectric actuators and a displacement coupling means for coupling the displacements of the actuators at different angles and outputting the obtained displacement. The plurality of actuators are driven by alternating current signals that are in synchronism with each other so that a motion output end can move along a desired curve. When one or a plurality of such drive apparatuses are used and outputs of the respective drive apparatuses are transmitted to a moving part or the like through a non-contact power transmitting means using magnetic poles or the like, a high-reliability motor unit having a resolution on the order of submicrons is realized.

Abstract: A vacuum brake booster assembly comprising front and rear housing shells connected to form a single piece their output peripheral edges and mounted within the passenger compartment of a vehicle, a piston body axially movable in the housing shells, a diaphragm member hermetically secured at its inner peripheral edge to the piston body and clamped at its outer peripheral edge by the outer peripheral edges of the housing shells to subdivide the interior of the housing shells into a vacuum chamber and a variable pressure chamber, and a pressure control valve cooperable with the piston body for selectively communicating the variable pressure chamber to the vacuum chamber or the atmospheric air in response to movements of the piston body, wherein at least the rear housing shell is formed as a double or multi layer wall for the variable pressure chamber to dampen air suction noises caused by expansion and vibration of the air flowing through the valve into the variable pressure chamber from the passenger compartment

Abstract: A four link suspension system for a monocoque vehicle body, which comprises a pair of upper control arms and a pair of lower control arms adapted to swingably support a rigid axle housing encasing an axle shaft against the body. The body has a floor panel, and a pair of side members spaced from each other in a transverse direction of the body, are provided at both sides of the panel. A cross member is disposed between both side members with a distance from the floor panel and secured at its both ends to the side members. The upper control arms are disposed inside of the lower control arms, and each forward end of the upper control arms is pivoted to said cross member.
