摘要:
The present invention provides parts of a rotation machine, which effectively prevent particulates, such as silica, iron oxide, and other particles, contained in a gas to adhere, in the rotating machines, which treat with the gases containing the particulates. An intermediated metal-plated film 11 and the plated film 12 containing the fluorocarbon polymer particles provided on the intermediate metal-plated film 11 are deposited on the surfaces of moving blades 23 used in a steam turbine. The plated film 12 containing the fluorocarbon polymer particles includes fluorocarbon polymer particles 13P made of any of Ni-based metals and a plated matrix 13M, and some of the fluorocarbon polymer particles 13P are exposed from the surfaces of the plated matrix 13M.

A rotor includes a plurality of holding cavities for holding specimen containers, respectively. A transverse cross sectional shape of the holding cavity is a substantially triangular shape having one vertex on an inner circumference side of the rotor. Two vertices of the substantially triangular shape are arranged on an outer circumference side of the rotor so as to have equidistance from a rotary shaft of the rotor. Spacing between sides of the substantially triangular shape in a circumferential direction of the rotor gradually increase over 60% or more a radial length of the holding cavity from an innermost circumferential position to the outer circumference side of the rotor when viewed in its transverse plane.

A time information repeating installation in a radio clock system, which receives advance notice information, distinguishes advance notice content by detecting means 9, sets a transmission start time by addition setting means 10 in accordance with the content, sets an additional period by change period setting means 11, and stores the content into transmission start time storage means 12. When the stored time agrees with the time of a main counter 8, transmission starts. Therefore, even when a sudden time change occurs, the repeating installation can perform transmission at the reception timing of a subsidiary device. The subsidiary device can effectively update time data for summer or daylight savings time.
