Abstract: A delivery planning device is provided to efficiently cope with delivery requirements of a loading place, an off-loading place, a cargo amount, a car loading vehicle, and a work shift of a driver that fluidly change. A delivery planning device receives and registers one or more delivery requests relating to deliveries between predetermined points. The delivery requests are divided into deliveries in one or more areas for which drivers of a predetermined number of delivery vehicles are responsible according to the predetermined number of the delivery vehicles; and a vehicle route planning unit specifies a delivery route and a cost relating to deliveries for each combination of a candidate for a relay place between the areas and a relay time in the candidate for the relay place, and specifies the delivery route as a vehicle route using the cost.

Abstract: A base plate of a disk drive apparatus includes a motor base disposed around a central axis and a base body portion extending radially outward of the motor base. The motor base is made of a metallic material of a first type. The base body portion is made of a metallic material of a second type. Thus, the axial thickness of a portion of the base plate close to the central axis can be significantly reduced and a reduction in the stiffness of the portion can be prevented. Further, the motor base includes a flange portion and a plastic deforming portion. The flange portion and the plastic deforming portion are respectively in contact with at least a portion of both axial end surfaces of an inner end portion of the base body portion. Thus, extraction of the motor base in the axial direction is prevented.

Abstract: A housing member for use in a disk drive apparatus includes a rectangular bottom portion and a side wall portion arranged to extend upward from an outer circumferential portion of the bottom portion. The side wall portion includes four outside surfaces including a first outside surface and a second outside surface perpendicular or substantially perpendicular to the first outside surface. The first outside surface includes a first cutting base region. The second outside surface includes a second cutting base region. The bottom portion includes a bearing fixing portion arranged to fix a bearing mechanism of a motor arranged to rotate a disk.

Abstract: A method of manufacturing a fluid dynamic bearing in which a stopper is fixed by welding. The bearing comprises a hub, a shaft erected on the hub, a sleeve, a cylindrical wall erected on the hub, and the stopper mounted on the cylindrical wall. The method comprises a first step to hold oil in the bearing gap, and a second step to locate the stopper on the peripheral wall being apart from the interface of the oil to fix the stopper by LASER welding.
