A zirconia sintered body having not only high strength but also excellent aesthetic properties. A colored translucent zirconia sintered body, characterized by containing an iron compound and from 2 to 4 mol % of yttria, showing a lightness L* of from 51 to 80 in L*a*b* color system, and having a relative density of at least 99.80%. The colored zirconia sintered body preferably has a total light transmittance of at least 20% as measured at a sample thickness of 1 mm and with a D65 light source. The colored translucent zirconia sintered body has aesthetic properties equivalent to those of natural teeth and is particularly suitable for a zirconia sintered body to be used for dental applications, and further, suitable for a mill blank such as an artificial tooth material or the like, and an orthodontic bracket.

摘要:
A subject of the invention relates to providing a powder for a translucent zirconia sintered body which is necessary for the production of a zirconia sintered body having a high sintered-body density and high strength and giving an excellent sense of translucency, without conducting any special sintering, such as HIP sintering. The invention relates to a technique for obtaining, through normal-pressure sintering, a translucent zirconia sintered body characterized by comprising zirconia which contains 2-4 mol % yttria as a stabilizer and has an alumina content of 0.2 wt % or lower, and by having a relative density of 99.8% or higher and a total light transmittance, as measured at a thickness of 1.0 mm, of 35% or higher. It is preferred that a powder containing 0-0.2 wt % alumina with a particle diameter of 0.01-0.5 μm, having a BET specific surface area of 5-16 m2/g and an average particle diameter of 0.3-0.7 μm, and having a rate of sintering shrinkage in normal-pressure sintering (Δρ/ΔT; g/cm3·° C.) of 0.0125 or higher but 0.0160 or lower should be subjected to normal-pressure sintering in the atmosphere.

摘要:
A compressor including a compressing mechanical unit which inhales a refrigerant excluding chlorine, compresses the refrigerant, exhales the compressed refrigerant, and collects a refrigerating machine oil O compatible with the refrigerant, thereby lubricating the compressing mechanical unit with the refrigerating machine oil O. The compressor further includes an electric motor unit for driving the compressing mechanical unit. The electric motor unit includes a stator and a rotor, and is driven by an inverter. The stator includes three-phase wires and a stator core, wherein the stator core includes a yoke section and teeth sections on which the three-phase wires are wound, and the wires are wound on the teeth sections such that the wires on adjacent teeth sections have different phases.

A method of magnetizing a permanent magnet motor involves inserting a spacer in between multi-layered windings (24Ua and 24Va) wound on a plurality of magnetic pole teeth when magnetizing an unmagnetized magnet (26), and removing the inserted spacer (28A) after finishing the magnetization. The spacer (28A) is also inserted in a space between two stator windings (24Ua, 24Va; 24Ub, 24Vb) wound on two magnetic pole teeth adjacent to each other, a magnet material is magnetized by electrifying the stator windings with a direct current in a state of the spacer (28A) being inserted, a permanent magnet is thus formed, and the spacer (28A) is removed after finishing the magnetization.
