An object is to alleviate the concentration of an electric field in a semiconductor device. A gate electrode and a drain electrode are provided not to overlap with each other, and an electric-field control electrode is provided between the gate electrode and the drain electrode over a top surface. Insulating layers are provided between the gate electrode and a semiconductor layer and between the electric-field control electrode and the semiconductor layer, and the insulating layer provided between the electric-field control electrode and the semiconductor layer has a larger thickness than the insulating layer provided between the gate electrode and the semiconductor layer. Further, when the semiconductor device is driven, the potential of the electric-field control electrode may be higher than or equal to a source potential and lower than a gate potential, and for example, connection between the electric-field control electrode and the source potential enables such a structure.

A power conversion apparatus capable of suppressing adverse effects of noise caused by crossing of wiring patterns on a wiring board mounting the apparatus thereon. The apparatus includes a transformer, a switching element connected to the transformer, a feedback rectification circuit, and a control circuit operable to control the switching element in response to a DC voltage from the feedback rectification circuit. A first wiring pattern electrically connecting the feedback rectification circuit and the control circuit is formed in one of two surface regions of the wiring board separated by an imaginary line running through a junction of the first wiring pattern and the feedback rectification circuit and a junction of the first wiring pattern and the control circuit, and a second wiring pattern electrically connecting the control circuit and the switching element is formed outside an area enclosed by the imaginary line and the first wiring pattern.

An apparatus is provided for detecting a malfunction occurring in an electromagnetic brake of a robot. In the apparatus, the main relay and the sub-relay are controlled to open the main contact and the sub-contact when the robot is activated. Detecting is then made whether or not the main contact is malfunctioning, by monitoring an energized state of the main contact. Activation of the robot is stopped when the main contact is malfunctioning and the main relay is controlled to close the main contact for a given period of time when that the main contact is operating normally. Detecting is further made as to whether or not the sub-contact is malfunctioning, by monitoring an energized state of the sub-contact The activation of the robot is stopped when the sub-contact is malfunctioning and the main relay is controlled to close the main contact when the sub-contact is operating normally.

An object is to provide a memory device including a memory element that can be operated without problems by a thin film transistor with a low off-state current. Provided is a memory device in which a memory element including at least one thin film transistor that includes an oxide semiconductor layer is arranged as a matrix. The thin film transistor including an oxide semiconductor layer has a high field effect mobility and low off-state current, and thus can be operated favorably without problems. In addition, the power consumption can be reduced. Such a memory device is particularly effective in the case where the thin film transistor including an oxide semiconductor layer is provided in a pixel of a display device because the memory device and the pixel can be formed over one substrate.
