Abstract: A reflective mask blank includes a substrate; a multilayer reflective film that reflects EUV light; a protection film that protects the multilayer reflective film; and a phase shift film that shifts a phase of the EUV light. The phase shift film contains Ir as a main component. A ratio of a maximum value of an intensity of a peak of diffracted light from the phase shift film in a 2? range of 35° to 45° to an average value of an intensity of the diffracted light in a 2? range of 55° to 60° measured using an XRD method with a CuK? ray, upon being irradiated with the EUV light with an incident angle of ?, is 1.0 or more and 30 or less. A refractive index and an extinction coefficient of the phase shift film to the EUV light are 0.925 or less, and 0.030 or more, respectively.

Abstract: A sintered magnet body (RaT1bMcBd) coated with a powder mixture of an intermetallic compound (R1iM1j, R1xT2yM1z, R1iM1jHk), alloy (M1dM2e) or metal (M1) powder and a rare earth (R2) oxide is diffusion treated. The R2 oxide is partially reduced during the diffusion treatment, so a significant amount of R2 can be introduced near interfaces of primary phase grains within the magnet through the passages in the form of grain boundaries. The coercive force is increased while minimizing a decline of remanence.

Abstract: A robot system includes a manipulator having a plurality of axes and driven by a motor provided for each axis, a robot controller, an encoder attached to the motor for each axis, an encoder wiring line connecting the encoder with the robot controller, a storage part in the manipulator which stores mechanical parameters including identification information for discriminating the encoder for each axis, and a control part in the robot controller which reads out the mechanical parameters from the storage part and communicates with the encoder through the encoder wiring line. The control part discriminates whether the identification information read out from the encoder and the identification information included in the mechanical parameters are coincided with each other or not for each axis and, when both the identification informations are not coincided with each other, the control part determines that erroneous wiring exists in the encoder wiring line.

The acquisition device acquires first and second diagnostic target data obtained in a manner that an image forming device forms a test pattern on each of a first medium and a second smaller medium with the first medium having a long side in agreement with that of the second medium in a conveying direction and an image reading device reads the first medium and reads the second medium rotated such that the long side of the second medium is different in direction from that of the first medium. The circuitry detects an abnormal area and diagnoses an abnormality factor, with the pattern, the first and second data, and third diagnostic target data obtained by rotating the second data such that the long side of the second medium is identical in direction to that of the first medium.

Abstract: A sintered magnet body (RaT1bMcBd) coated with a powder mixture of an intermetallic compound (R1iM1j, R1xT2yM1z, R1iM1jHk), alloy (M1dM2e) or metal (M1) powder and a rare earth (R2) oxide is diffusion treated. The R2 oxide is partially reduced during the diffusion treatment, so a significant amount of R2 can be introduced near interfaces of primary phase grains within the magnet through the passages in the form of grain boundaries. The coercive force is increased while minimizing a decline of remanence.
