Abstract: In a fluid power generator system using operative fluid energy, a measured tip speed ratio and a reference tip speed ratio are compared with each other. If the measured tip speed ratio is smaller than the reference tip speed ratio, a generator is placed in a no-load state, thereby restoring the number of rotations of the wing axial shaft to the number of rotations corresponding to the reference tip speed ratio. Further, the operation of the generator is controlled on the basis of the tip speed ratio calculated from the flow rate of the fluid, thereby providing a maximum output for each flow rate. In this way, a change in the flow rate and number of rotations can be appropriately dealt with and the maximum output for each flow rate of the operative fluid can be dealt with, thereby increasing a quantity of generated power.

Abstract: A confocal microscope apparatus has a confocal scanner for scanning a sample with shifting a focal position of a light beam in a direction perpendicular to an optical axis, a moving mechanism for moving the focal position of the light beam in an optical axis direction, a camera for picking up an image of the sample with the light beam, and a movement control unit for controlling the moving mechanism to move the focal position of the light beam by a predetermined distance in the optical axis direction for every vertical synchronizing signal of the camera in synchronization with the vertical synchronizing signal. A high-speed three-dimensional image can be displayed in such that while measuring the sample, two or more slice images in such an arrangement on a common screen that their positions relative to the sample enables to be grasped.

Abstract: A fluid power generator system includes an operating mode in which a continuously variable output corresponding to a wide range of a flow rate is given by selectively combining generators with optimum rated outputs from said plurality of generators according to natural fluid energy and the number of rotations of a wing axial shaft; and control means for controlling the operation of each of the generators on the basis of a tip speed calculated from the flow rate of the operative fluid and the number of rotations of said wing axial shaft, thereby acquiring a maximum output for specific flow rate of the operative fluid. In this configuration, the fluid power generator system using operative fluid energy as a driving source can generate a continuously variable output corresponding to a wide range of the flow rate of the fluid and provides a maximum output for an individual flow rate of the operative fluid, thereby increasing a quantity of generated power (by 40% or more than before).

The screw attachment includes a pair of arms (12, 13) made of a shape restoring material. Each arm has a fore end, and the fore ends are joined to each other with an adhesive material that is softened when heated. The arms expands radially such that the screw attachment is released from the head of the fastening piece when heat or force is applied to the arms.
