  • Publication number: 20240070581
    Abstract: An information processing method, for an information processing apparatus including a controller, includes a first step, by the controller, of acquiring positional information indicating a change over time in positions of a plurality of users, a second step, by the controller, of predicting a number of the users who will gather at a specific time at a boarding/alighting point to board/alight from a vehicle based on the change over time in the positions of the plurality of users indicated by the positional information, and a third step, by the controller, of determining a vehicle dispatch schedule for the vehicle to the boarding/alighting point based on the number of users predicted to gather at the specific time at the boarding/alighting point.

  • Patent number: 4871400
    Abstract: A method for producing a titanium strip having a small proof strength anisotropy and an improved ductility comprises the steps of: reheating a hot rolled titanium strip containing 0.1% by weight or less of oxygen and 0.1 to 0.5% by weight of iron at a .beta. region temperature and cooling by water, aging the obtained titanium strip at a temperature of 200.degree. to 500.degree. C. for 30 minutes or more, cold rolling the titanium strip at a rolling reduction of 30% or more; and, annealing the cold rolled titanium strip at a temperature of 600.degree. to 800.degree. C.

  • Patent number: 4132342
    Abstract: In a method for producing a hot strip by hot rough rolling, a steel slab heated to a rolling temperature to obtain a steel band, and hot finishing rolling the steel band in a continuous manner, the improvements comprising overlapping a forward end portion of a steel band which is being rolled by the rough hot rolling over a finishing end portion of a similarly rolled preceding steel band before or during the hot finishing rolling step, with insertion between the overlapped portions of the both hot bands of an oxide scale-fusing agent which reacts with the oxide scale present on the opposing surfaces of the overlapped portions by the heat of the overlapped portions and forms a low-melting point substance, fixing temporarily the overlapped portions by means of a metallic nail-like member driven into the overlapped portions, bonding the overlapped portions by reduction, and subjecting the steel bands thus bonded to the hot finishing rolling continuously.
