Abstract: A wireless communication device includes a processor; and a memory configured to store a program, the program being executed by the processor to cause the processor to: change a RADIUS reauthentication interval used by a RADIUS server based on a number of RADIUS reauthentication failures for each of a plurality of communication terminals connected to the wireless communication device, and a first threshold.

Abstract: To collect highly accurately filter-processed data. Sensor signals are acquired from sensors in predetermined data acquisition periods, a filtering process is performed on the sensor signals, time series data generated by extracting some of the filtered sensor signals is transmitted to an external device in a predetermined data transmission period that is longer than the data acquisition period, and the data transmission period is synchronized with a communication period of the external device.

Abstract: The present invention provides a more practical hard-coated cutting tool having improved cutting performance during finishing so as to obtain a better finished surface. Provided is a hard-coated cutting tool including a tool body (7) coated with a hard coating (4) and having a cutting edge (3) formed on a ridge line intersecting a flank face (1) and a rake face (2). In the hard-coated cutting tool, the thickness h1 of the hard coating (4) on the flank face (1) side and the thickness h2 of the hard coating (4) on the rake face (2) side near the cutting edge (3) satisfies conditions 8 ?m?h1?30 ?m and 0?h2/h1?0.5 in a cross-section perpendicular to the cutting edge (3) in a range equal to or less than 0.3 times the tool diameter in the axial direction from the tip of the tool.

Abstract: There is provided a diamond film for cutting-tools which has high toughness, excellent adhesiveness, high hardness, and in which tool service life is considerably improved in relation to cutting ultra-hard alloys and other very hard work materials. A diamond film for cutting-tools formed on a base material, in which at least one or more multilayered film layers [A] are included in which the layers are constituted by layering a film layer [?] having a film thickness of 1 ?m or more and 15 ?m or less and a film layer [?] having a film thickness of 1 ?m or more and 20 ?m or less so that the film layer [?] is disposed on the base material side and the film layer [?] is disposed on the surface layer side; the film thickness of the entire film body is set to 4 ?m or more and 30 ?m or less; and the film layer [?] and the film layer [?] have predetermined film compositions.

Abstract: In this offset printing apparatus, a plate table (4) and a substrate table (6) are provided in a manner capable of traveling on guide rails (2) that are provided on a trestle (1). A transfer mechanism portion (9) that is provided with a blanket roll (10), lift actuators (13) of the blanket roll, a height sensor (14) of the blanket roll, and a pressure sensor (15) that detects the contact pressure of the blanket roll with respect to the plate (3) and the substrate (5) is provided at a position corresponding to the middle portion in the longitudinal direction of the guide rails (2). Also, a controller controls the lift actuators (13) so that the contact pressure that is detected by the pressure sensor (15) when the blanket roll (10) is brought into contact with the plate (3) and the substrate (5) becomes a predetermined value.

Abstract: An offset printing method of the present disclosure brings a blanket roller from above into contact with a plate held on a plate table traveling on guide rails on a mount, and then brings the blanket roller into contact with a print target held on a print target table traveling on the guide rails, to thereby perform transfer of a print pattern from the plate to the blanket roller and re-transfer of the print pattern from the blanket roller to the print target. The method further includes the steps of: causing a plate to be held on an alignment stage provided on an upper portion of the plate table and also causing a print target to be held on an alignment stage provided on an upper portion of the print target table; and correcting a position of the plate by the alignment stage of the plate table and also correcting a position of the print target by the alignment stage of the print target table.

Abstract: An ink return blade 17, an ink filling blade 18, and an ink removal blade 19 are disposed in order at a retreat height that is higher by a predetermined dimension than the plate 10 retained in the plate table 11, and are supported by a supporting frame 20 at a predetermined position on a pedestal 8 of an offset printing apparatus. Separate elevating/lowering actuators 21, 22, 23 are provided for each blade 17, 18, 19. When the plate table 11 that retains the plate 10 is driven in one direction, after ink from an ink pool 25 on the plate 10 is filled into the plate 10 by the ink filling blade 18, and excess ink is removed by the ink removal blade 19. Therefore the plate 10 with a suitable amount of inking thereon can be supplied for printing operations. Thereafter, when the plate table 11 is driven in the opposite direction, the ink return blade 17 is brought into contact with the plate 10, and the ink pool 25 is returned to an initial position.
