Abstract: A receiving side server as a data management server is provided with: a reacquisition condition management unit that records and manages reacquisition condition information in which information related to a data file stored in a database is associated with reacquisition available/unavailable information related to the possibility of acquisition of the data file; a data transmission unit that registers a reacquisition condition information of a data file in the reacquisition condition management unit on the basis of reacquisition available/unavailable information attached to a data file provided externally, and transmits the provided data file to the database; and a data acquisition unit that, upon reception of an acquisition request for the data file stored in the database, acquires the data file from the database only if acquisition of the data file is permitted on the basis of the reacquisition condition information managed by the reacquisition condition management unit.

Abstract: When a data provider provides data to the outside, an application not intended by the data provider to use the data is prevented from doing so. A reception-side server comprises a data usage condition information management unit which: when available application information, in which an application name for allowing access to data provided from outside is set, is added to the data, registers data usage condition information; and when an access request for the data is received from any application, allows access to the data only to applications that are authorized to access the data on the basis of the data usage condition information.

Abstract: A pneumatic tire has a pair of sidewall portions. An outer surface in a tire axial direction of at least one of the sidewall portions includes a base surface, at least one first protruding portion protruding more outward in the tire axial direction than the base surface, and a recessed portion extending on the base surface around the first protruding portion such that the first protruding portion is spaced apart from the base surface. The first protruding portion includes a first surface having a first protruding amount with respect to the base surface, and a second surface having a second protruding amount different from the first protruding amount with respect to the base surface, and the first surface and the second surface are connected so as to form a step.

Abstract: A pneumatic tire includes a tread portion and a pair of sidewall portions each extending inwardly in a tire radial direction from the tread portion. At least one of the pair of the sidewall portions is provided with at least one side protector protruding outwardly in a tire axial direction. The side protector is provided with a groove, a cut-out portion connected with the groove, and a sipe connected with the groove.

Abstract: A tire comprises a tread portion having at least one main groove extending in a zigzag manner in a tire circumferential direction. The main groove includes first inclined portions and second inclined portions arranged alternately in the tire circumferential direction. The first inclined portions are inclined in a first direction and the second inclined portions are inclined in a second direction opposite to the first direction with respect to the tire circumferential direction. A length of each of the first inclined portions is larger than a length of each of the second inclined portions. The main groove is provided in a groove bottom thereof with projecting portions extending in a groove width direction of the main groove. The projecting portions includes first projecting portions arranged in the first inclined portions.

Abstract: A numerical controller of the present invention includes a parameter setting unit which accepts settings of punch press parameters, an NC parameter calculating unit which calculates an axis control parameter in punch pressing based on the punch press parameters, a parameter storage unit which stores the punch press parameters and the axis control parameter, a command analyzing unit which analyzes a command block in the program to generate movement command data, an interpolating unit which generates interpolation data based on the movement command data, and an accelerating and decelerating unit which calculates a linear acceleration and deceleration time constant and a bell-shaped acceleration and deceleration time constant for use in axis control based on the punch press parameters, the axis control parameter, and a feed rate specified by the command block and performs post-interpolation acceleration or deceleration processing based on each of the calculated acceleration and deceleration time constants.
