Abstract: In a cross section of the hub part of the railway wheel, obtained when the hub part is cut in a central axis direction of the through hole along a plane including a central axis, when regions of 15 mm×15 mm defined by a plurality of axial line segments parallel to the central axis and arranged at a pitch of 15 mm in a radial direction from an inner peripheral surface of the through hole, and by a plurality of radial line segments perpendicular to the central axis and arranged at a pitch of 15 mm in the central axis direction from a surface of the hub part in which an opening of the through hole is formed are defined as rectangular regions, the average C concentration in each rectangular region in the cross section of the hub part is less than 0.90% by mass.

Abstract: A personal information system includes an acquisition unit, a storage unit, a personal storage unit, and a control unit. The acquisition unit is configured to identify an occupant of a vehicle and acquire a status of the occupant. The storage unit stores usage history information of a vehicle device and state information of the occupant acquired by the acquisition unit. The personal storage unit is set for each occupant and is configured to retrieve, as personal information, the usage history information and the state information from the storage unit for each occupant and sequentially store the usage history information and the state information. The control unit is configured to perform control that utilizes the personal information stored in the personal storage unit to provide a service, in a manner matching characteristics of each occupant when operating the vehicle device.

Abstract: A device for mobile object, which is usable in a mobile object, includes an occupant information specifying unit and a request estimation unit. The occupant information specifying unit specifies an occupant information record for each of multiple occupants existing in the mobile object by distinguishing the multiple occupants from one another. The multiple occupants are detected by a sensor of the mobile object. The request estimation unit estimates a request of one of the multiple occupants corresponding to a combination of the occupant information records of the multiple occupants based on the occupant information records of the multiple occupants specified by the occupant information specifying unit.

Abstract: In a technique for controlling a first vehicle, display information and position specifying information are received from a second vehicle different from the first vehicle via inter-vehicle communications. The display information is information for display and independently set for the second vehicle in the second vehicle. The position specifying information is information for specifying a position of the second vehicle. The position of the second vehicle relative to the first vehicle is specified based on the position specifying information. Display on a display device is controlled to superimpose information indicated by the display information on the position of the second vehicle in a landscape in front of the first vehicle based on the position of the second vehicle and the display information.

Abstract: A human machine interface is configured to select an information display destination from among a plurality of display areas. The HCU acquires a sight line direction of a driver based on an image of an in-vehicle camera. The HCU displays, upon detecting a hop-off action of the driver based on an output signal of an in-vehicle sensor in a situation in which an attention target event such as a puddle, a step, other vehicle or the like exists on a road surface near a door of a driver's seat, in the display area corresponding to the driver's sight line direction, text or an image practically indicating (a) a content of an attention target event or (b) how to deal with a situation.

Abstract: Elastic foamed products or articles having a much better heat resistance than that of the asbestos fiber foamed mass, prepared by drying of an aqueous fiber-dispersed slurry retaining bubbles and consisting essentially of inorganic fibers, synthetic fluormica of the non-restrictive swelling type and surface active agents. In the elastic foamed products, the inorganic fibers having films of the fluormica formed therebetween are evenly entangled with each other, said films having bubbles retained therein.
