An overvoltage protection circuit includes a PMOS transistor Q1 that is disposed between an input circuit 21, from which an input voltage VIN is supplied, and a system 22 and functions as a switch. A comparator 110 compares the input voltage VIN with a predetermined reference voltage to determine the occurrence of an overvoltage. Further, the comparator 110 outputs a High level as an operation signal when no overvoltage is detected. A soft switching control circuit 130 starts up by using the High level output from the comparator 110 as an enable signal, and gradually turns on the PMOS transistor Q1. A sudden change of the load exerted on the circuit on the input side is suppressed by the soft start function.

[Object]When the CW laser is employed for annealing the semiconductor film, a device having a high characteristic can be expected. On the other hand, when the beam shaped to be elliptical is scanned on the semiconductor film, a proportion of excimer-like crystal grain region becomes large and this is a problem in point of high integration. The present invention is to make the excimer-like crystal grain region formed over the semiconductor film as small as possible. [Solution]In the present invention, a fundamental wave having a wavelength of approximately 1 μm is irradiated supplementarily to the semiconductor film, which is the irradiated surface, simultaneously with a harmonic emitted from a CW laser. In addition, the fundamental wave is irradiated with a large amount of energy to a region irradiated by the harmonic with a small amount of energy, and the fundamental wave is irradiated with a small amount of energy to a region irradiated by the harmonic with a large amount of energy. Thus it becomes possible to form the long crystal grain region in the semiconductor film while suppressing the formation of the excimer-like crystal grain region.

A shape of the prism in a cross-section perpendicular to a longitudinal direction of the prism line is formed by a side A on a lower side at an angle of α degrees to a normal line of the exit surface and a side B on an upper side at an angle of β degrees to the normal line of the exit surface and α<β, and 40 degrees≦β≦80 degrees. An integral value of a downwardly emitted light flux is 55% or more of the total integral value of an upwardly emitted light flux and the downwardly emitting light flux when predetermined diffusion light enters one surface of the plastic sheet in a direction perpendicular to the plastic sheet.

In a steering control apparatus, a basic assistance torque calculating unit calculates a basic assistance torque. A return control unit calculates a return control amount to assist in returning a steering wheel to a neutral position, as a correction torque to be added to the basic assistance torque. In the return control unit, a target steering speed calculating unit calculates a target steering speed being that is a target value for a steering speed. A return control amount calculating unit calculates the return control amount such that the steering speed follows the target steering speed. A returning state determining unit determines whether the steering wheel is turning or returning. The target steering speed calculating unit gradually increases an absolute value of the target steering speed from an absolute value of the steering speed when the steering wheel is returning.

Characteristic lines A to D of lateral acceleration G-required torque T in determination of required torque T are used as switched according to increase / decrease of the absolute value of the lateral acceleration, and the direction thereof. The lines A, C used in increase of the absolute value of the lateral acceleration G are so set that the absolute value of required torque T becomes larger at the same lateral acceleration G (G≠0) than that with the lines B, D used in decrease of the absolute value of the lateral acceleration G. The difference between line A and line B (the difference between line C and line D as well) at the same lateral acceleration G is so set that the difference near the lateral acceleration of 0 is smaller than that in the other regions. Particularly, it is preferable to set the required torque T to 0 at the lateral acceleration G of 0.

A correction-term adder 1 compares a maximum value max(V*) with an absolute value of a minimum value min(V*). The correction-term adder 1 selects a signal 1−max(V*) when the maximum value max(V*) is larger than the absolute value of the minimum value min(V*), on the other hand, selects a signal −1−min(V*) when the absolute value of the minimum value min(V*) is larger than the maximum value max(V*). Thereby, a signal of correction amount α is calculated. Moreover, the correction-term adder 1 produces a triangular-wave-shaped signal k(max(V*)+min(V*)) by multiplying a gain k by an addition signal max(V*)+min(V*) of the maximum value max(V*) and the minimum value min(V*). This triangular-wave-shaped signal k(max(V*)+min(V*)) is synchronized with the correction amount α. The correction-term adder 1 produces a correction amount β by selecting smaller one in absolute value between the triangular-wave-shaped signal k(max(V*)+min(V*)) and the correction amount α, and adds the correction amount β to the voltage command values V*U, V*V, V*W.
