Abstract: According to one embodiment, when sending a transmission target main data 21, an authentication-tag generator unit 13 generates an authentication tag 23 by using a main data 21 and a key data 22 stored in a key-data storage unit 12. A transmitter/receiver unit 14 adds the authentication tag 23 to the main data 32 sends as a transmission data. When receiving the received data 24a, the transmitter/receiver unit 14 divides the received data into a main data 21a and an authentication tag 23a. The authentication-tag generator unit 13 generates an authentication tag 23b for comparison. A received-data authentication unit 15 determines whether or not those the received authentication tag 23a and the authentication tag for comparison 23b match with each other. A different key data is used every time upon the authentication-tag generation and use time of each key data during a set period is restricted.

Abstract: A tank (10) of a ship (1) is provided with an inflow port (6) and an outflow port (7) opening through a bottom of the ship (13). The inflow and outflow ports are spaced apart from each other in a headway direction of the hull. The ports are equipped with closure means (9), which closes the ports so as to ensure hull buoyancy by means of air in the tank. The ports allow seawater outside the ship to flow into the tank through the inflow port and the seawater in the tank to flow out of the ship through the outflow port, with use of headway motion of the ship. A partition (2) provides a weir extending in a widthwise direction of the hull in the tank, and divides a region in the tank into an inflow area (3) and an outflow area (4). The tank, partition, inflow port, outflow port and closure means constitute a ship buoyancy control system.

Abstract: The present invention provides a rotary-type fluid machine which enables practical and effective operation in an extremely low specific speed range. The rotary-type fluid machine (1, 1?) has an impeller (10, 10?) integrally connected to a rotating drive shaft (2). The impeller is accommodated in a casing (3). Fluid (a) of a suction fluid passage (4) to be pumped flows into a center part (11) of the impeller. The fluid (b) is discharged from a peripheral portion (12) of the impeller by the effect of the centrifugal force of the rotating impeller, so that the fluid is delivered through a delivery fluid passage (5) outside of the casing. Many grooves (15) extending toward a peripheral edge of the impeller from the center part of the impeller are formed on the impeller. The groove opens on an outer circumferential surface (18) of the impeller, and causes strong recirculation vortices (R) to be formed in the vicinity of the peripheral edge of the impeller when the impeller rotates.

Abstract: According to a reception passive intermodulation measurement method of the present invention, a device under test is set to the mismatching condition, and a standing wave is generated on a transmission line where the sample is connected. Since the tip of the transmission line is short-circuited using the sample, the sample is positioned at the anti-node of the standing wave, and test signals are applied at a high current density. System noise is calibrated with the tip of the transmission line being open. Since impedance matching is not required and terminators are not employed, a large measurement dynamic range is obtained without being affected by passive intermodulation that is generated in terminators. The sample is very small, and an arbitrary shape can be selected. The property measurement is enabled for a wide range of materials, regardless of a conductive material, an insulating material and a magnetic material.

Abstract: When an interpolation point is interpolated using a curve/curved surface, represented by control points, such as a B-Spline curve/curved surface or a subdivision surface, interpolation processing is performed in such a way that a moving vector for moving each control point is calculated using position information on interpolation points constituting the point group, as well as vector information on the unit direction vector that is set for each interpolation point, and the control point is moved in the movement direction and for the movement amount of this moving vector. By, repeating the generation step of a curve/curved surface that interpolates the interpolation point and the movement step of the control point, the position of a new control point is found that fits the curve/curved surface to the positions and the unit direction vectors of the point group.
