Abstract: A resistance calculation activator determines whether or not an electric car is stopped on the basis of a drive command signal and an external signal, and activates a resistance calculator if a powering command is input as the drive command when it is determined that the electric car is stopped. The activated resistance calculator computes, within a resistance calculation period, a resistance value of an AC motor that produces driving force for the electric car, on the basis of a d-axis voltage command value and a d-axis current value supplied to the AC motor.

Abstract: The purpose is manufacturing a photoelectric conversion device with excellent photoelectric conversion characteristics typified by a solar cell with effective use of a silicon material. A single crystal silicon layer is irradiated with a laser beam through an optical modulator to form an uneven structure on a surface thereof. The single crystal silicon layer is obtained in the following manner; an embrittlement layer is formed in a single crystal silicon substrate; one surface of a supporting substrate and one surface of an insulating layer formed over the single crystal silicon substrate are disposed to be in contact and bonded; heat treatment is performed; and the single crystal silicon layer is formed over the supporting substrate by separating part of the single crystal silicon substrate fixed to the supporting substrate along the embrittlement layer or a periphery of the embrittlement layer. Then, irradiation with a laser beam is performed on a separation surface of the single crystal silicon layer through an optical modulator which modulates light intensity regularly, and unevenness is formed on the surface. Due to the unevenness, reflection of incident light is reduced and absorptance with respect to light is improved, therefore, photoelectric conversion efficiency of the photoelectric conversion device is improved.

Abstract: A fragile layer is formed in a region at a depth of less than 1000 nm from one surface of a single crystal semiconductor substrate, and a first impurity semiconductor layer and a first electrode are formed at the one surface side. After bonding the first electrode and a supporting substrate, the single crystal semiconductor substrate is separated using the fragile layer or the vicinity as a separation plane, thereby forming a first single crystal semiconductor layer over the supporting substrate. An amorphous semiconductor layer is formed on the first single crystal semiconductor layer, and a second single crystal semiconductor layer is formed by heat treatment for solid phase growth of the amorphous semiconductor layer. A second impurity semiconductor layer having a conductivity type opposite to that of the first impurity semiconductor layer and a second electrode are formed over the second single crystal semiconductor layer.

Abstract: A control apparatus for an AC rotary machine includes a control circuit, a power converter, a current detector, and a voltage detector. The control circuit includes: an activation current instruction unit which generates a current instruction for activation; and a start phase setting unit which sets an initial rotation phase for activation control, based on the rotation direction of the AC rotary machine just after activation and on the polarity of current detected by the current detector just after activation. Thus, the current amplitude and torque shock just after activation control is started can be reduced, and assured and stable reactivation is allowed without causing the protection operation.
