Abstract: A method and an apparatus of inspecting the surface of a wafer, where two or more kinds of laser are switched or mixed to make the laser incident on the film-coated wafer by a same incident angle, in which inspection data regarding an inspection apparatus and film parameters regarding a film are stored in storage means of the inspection apparatus in an associated state with each other so as to obtain predetermined inspection conditions. When performing each measurement, an operator sets the film parameters of the wafer to be measured by setting means of the inspection apparatus. Thus, desired inspection conditions are automatically set in the inspection apparatus. The film parameters that the operator sets at each measurement are a film thickness and a film refraction index.

Abstract: A magneto-optical recording medium has a recording layer and a reflective layer on a substrate. The recording layer has a layered structure in which at least one spinel ferrite (or rutile-type oxide or hematite) layer and at least one garnet ferrite layer are piled together. It is preferable that the layered structure is formed on tracks where data are recorded. A manufacturing method comprises the steps of heat treatment in the range of 500-700° C., preferably 600-630° C., after the formation of the recording layer. In the magneto-optical recording and playback device to record and play back data, the wavelength of light for recording data is different from that for reading data, which is preferable for a magneto-optical recording medium comprising a garnet ferrite layer.

Abstract: The present invention intends to provide a control device for a fuel cell vehicle which suppresses the deterioration of driveability upon acceleration without increasing the size of a driving electric motor or a motor driver. When a requested output (PD_CAL) exceeds a first output limit determined depending on a continuous output rating of an electric motor 10 or a motor driver 5 and an increasing rate of the requested output (PD_CAL) exceeds a reference increasing rate, an upper-limit target output determining unit 52 determines an assist time used as a time during which the electric motor 10 can be operated continuously by the requested output (PD_CAL) on the basis of the requested output (PD_CAL) and an open-circuit voltage (Vbat_o) of a battery 3. Until the assist time is elapsed, the upper-limit target output (PD_LMT) is set to a second output limit (>the first output limit) determined depending on a short-time output rating of the electric motor 10 or the motor driver 5.
