    • An electric power tool includes a three-phase bridge motor circuit including upper and lower switching units of U, V and W phases arranged in upper and lower rows; a brushless motor rotationally operated by an electric power supplied through the motor circuit; and temperature detecting units for detecting temperatures of the switching units to output detection results such that the operation of the brushless motor is restrained or stopped depending on the detection results outputted from the temperature detecting units. The motor circuit is formed by mounting the switching units at six points on a mounting surface of a circuit board, and the temperature detecting units are arranged on a surface of the circuit board opposite to the mounting surface.

    • An image reading apparatus can perform shading correction with a simple arrangement. Prior to an original read operation, a prescanning operation is performed using a white reference original. Shading data is formed by a shading correction circuit and held in both an internal shading memory and a memory in a shading data confirming unit. The shading data confirming unit compares the data in both the memories to detect whether the data is destroyed. If the data is destroyed, permanent shading data is used. When the image is a halftone image, the prescanning operation is performed again to form shading data. Therefore, a conventionally used prescanning mechanism for the reference white ground can be omitted. At the same time, even when the shading data is destroyed by an abnormal voltage or the like, processing can be normally performed.
    • 图像读取装置可以以简单的布置进行阴影校正。 在原始读取操作之前,使用白色参考原稿执行预扫描操作。 阴影数据由阴影校正电路形成,并保持在阴影数据确认单元中的内部阴影存储器和存储器中。 阴影数据确认单元比较两个存储器中的数据,以检测数据是否被破坏。 如果数据被破坏,则使用永久着色数据。 当图像是半色调图像时,再次执行预扫描操作以形成阴影数据。 因此,可以省略用于参考白色接地的常规使用的预扫描机构。 同时,即使阴影数据被异常电压等破坏,也可以正常进行处理。
