A steam turbine blade includes a coating film formed at least a portion of a surface of the steam turbine blade, the coating film containing a ceramic matrix and nanosheet particles dispersed in the ceramic matrix. The steam turbine blade is employed as one of stator blades or one of rotor blades in a steam turbine. The steam turbine includes a turbine rotor, the rotor blades implanted in the turbine rotor, the stator blades provided in an upstream side of the corresponding rotor blades, and a turbine casing supporting the stator blades and accommodating turbine rotor, the rotor blades and the stator blades. The steam turbine is also configured such that the rotor blades are paired with the corresponding stator blades to form turbine stages arranged in an axial direction of the turbine rotor, thereby forming steam paths.

An object of the present invention is to provide a new acetoacetic ester group-containing polyvinyl alcohol-based resin that contains less amount of water-insoluble matter and is excellent in transparency and viscosity stability when converted into an aqueous solution, and that realizes excellent water resistance by combined use of a crosslinking agent. The invention provides an acetoacetic ester group-containing polyvinyl alcohol-based resin containing a structural unit represented by the general formula (1): wherein at least one of R1 and R2 represents an acetoacetyl group, R3, R4, R5, R6, R7 and R8 each independently represents an arbitrary substituent, and X represents a single bond or an arbitrary bonding chain.

It is an object of the invention to realize effective communication by a mobile communication terminal having a plurality of communication interfaces.When transmitting data, a mobile communication terminal (100) selects a communication interface (102). The mobile communication terminal (100) transmits the data via a communication network (108) corresponding to the selected communication interface (102) to a mobile communication managing apparatus (200). The mobile communication managing apparatus (200) transfers the data to a communication apparatus (500). The mobile communication terminal (100) assigns a terminal identification address for uniquely identifying the mobile communication terminal (100) and a communication interface identification address for identifying the communication interface (102) that is valid in the communication network (108) to the transmission data.

The present invention provides a cell preparation that can be prepared from cells collected from a patient of any age group, and that has an excellent bone tissue regenerative capacity and is effective for bone tissue regeneration. Undifferentiated osteoblasts obtained from alveolar bone, particularly those obtained by being cultured after the enzyme treatment of alveolar bone have a remarkable bone tissue regenerative capacity, and are therefore useful for a cell preparation for bone tissue regeneration.
摘要:
There is provided a communication terminal out of range determination method, a wireless communication system switching method and a communication terminal, capable of determining accurately whether or not a communication terminal is out of range. Determining whether or not the communication terminal is out of range is based on a transmission level of a transmission signal from the communication terminal to a base station.
