In a multicast delivery system, A delivery server enciphers delivery data by using a current use cipher key to generate enciphered data and transmits a multicast packet containing the enciphered data and a current use key identifier indicative of a pair of the current use cipher key and a current use decipher key as current use keys. A key management server holds as a current use key data, a set of the current use decipher key and the current use key identifier, and transmits a set of the current use decipher key and the current use key identifier as a current use decipherment key data in response to a current use key data request.

Disclosed is a disk storage apparatus to control writing to a storage medium having a storage area to which a first address space is allocated and whose transfer rate spatially changes, including a command reception section and control section. The command reception section receives a write command from a host apparatus and containing an address of the first address space. The control section performs control to divide the storage area into zones, pre-define a second address space where blocks are successively allocated to the zones from a beginning address of the first address space, replace, for each of the write commands received by the command reception, an address of the first address space contained therein with an address of the second address space, select one of the zones as a write target zone by cyclical changing, and perform a writing process to the storage medium for each selected zone.

A production method for a sintered part comprises preparing a metal powder and a binder composed of a thermoplastic resin and a wax, mixing the metal powder and 40 to 60 vol. % of the binder with respect to the metal powder into a mixed powder, and heating and kneading the mixed powder into a raw material. This production method further includes supplying a predetermined amount of the raw material in a hole of a die and compacting the raw material into a green compact having a predetermined shape by pressing the raw material by a punch. This production method further includes ejecting the green compact from the hole of the die, removing the binder from the ejected green compact by heating, and sintering the green compact by heating so as to diffusion bond particles of the green compact. The compacting is performed by pressing at a moving rate U of the punch, which is not more than a rate calculated from the following equation (1). In this case, ΔP (Pa) is pressing power of the punch, μ (Pa·s) is viscosity of the raw material, L (m) is a length of the green compact, and De (m) is a corresponding tube diameter. U=ΔP/(32μ×L)×De2 (1)

摘要:
There is provided a rolling bearing including an inner ring having an inner ring raceway surface, an outer ring having an outer ring raceway surface and a shoulder portion formed on one axial side of the outer ring raceway surface, a plurality of rolling elements which roll between the inner ring raceway surface and the outer ring raceway surface, and a cage adapted to hold the plurality of rolling elements at predetermined intervals in a circumferential direction and having a guided surface which confronts the shoulder portion of the outer ring in such a manner as to be brought into sliding contact therewith. The rotation of the cage is guided through sliding contact of the guided surface of the cage with a guiding surface of the shoulder portion of the outer ring. A guiding space which is a radial space between the guiding surface of the shoulder portion of the outer ring and the guided surface of the cage is made to increase as approaching the rolling elements.

The present invention provides a molding die and a control method thereof aimed at shortening cycle time from heating to cooling of a molding cavity of the die with a simple and inexpensive configuration. In a molding die equipped with a molding cavity to mold a base material, a magnetic die material is used for the molding cavity, cooling means to feed a refrigerant is installed inside the molding cavity along a molding face and heating means by high-frequency induction is installed around the cooling means, and the molding cavity is alternately heated and cooled repeatedly by the heating means and the cooling means when the base material is molded with the molding cavity. Here, the cooling means includes a tubular body installed in the molding cavity, feeds a refrigerant when the molding cavity is cooled, and is in a hollow state of not containing the refrigerant when the molding cavity is heated.
摘要:
A printing paper winding device for enabling winding of printing paper even paper with a base material having a low resistance to bending stresses or printing paper having RFID labels carrying IC chips. Bending stresses are reduced by dividing the movement region of the tension roller into four regions in order to enable the successive detection of the position or posture of the tension roller and by making the bending angle of the printing paper in the winding path close to a more obtuse angle. A winding control unit of the present invention determines whether the tension region where the tension roller is positioned is a first tension region, second tension region, third tension region, or fourth tension region, controls the drive unit to limit the tension roller to a tension region in which winding is possible in the direction such that the bending angle of the printing paper in the winding path, which follows the winding of the printing paper, is close to a more obtuse angle.

A tread (14) of a tire (10) includes a tread rubber layer (16). The tread rubber layer (16) has a two-layer structure including a base layer (23) and a cap layer (24). The base layer (23) is provided with a comb-shaped convex portion (26). The convex portion (26) is formed like a circle extended in the circumferential direction of the tire (10). A plurality of convex portions (26) is arranged in the axial direction of the tire (10) and is protruded in a radial direction. At least a part of the convex portions (26) is exposed to a tread surface (17) when the tire (10) is unused (brand-new). The cap layer (24) contains silica and the base layer (23) does not contain the silica.
