    摘要: A grinding wheel is for use in a grinding machine, and is attached on a wheel spindle of the grinding machine for simultaneously grinding at least two parts of a workpiece. The grinding wheel includes at least two wheel cores. Each of wheel cores has a disk-like shape. An abrasive layer is disposed on a circumferential surface of each of the wheel cores. A spacer portion is inseparably fixed on at least one of the wheel cores for keeping a space between the abrasive layers of the wheel cores. And a first labyrinth portion located on one of side surfaces of one of the wheel cores for forming a labyrinth seal with a second labyrinth portion arranged on the grinding machine. The number of separable parts of the grinding wheel are extremely decreased in consideration of imbalance of every part. The spacer portion is integral with at least one of the wheel cores. Since the grinding wheel is easily accurately balanced, vibration of the grinding wheel is decreased and stability is enhanced when the wheel spindle is driven at very high speed. As a result, machining accuracy for grinding is enhanced.

A first gate electrode is formed on the gate insulating film. A first region and a second region having a first conductivity type are formed on or in a surface of the semiconductor film on opposite sides of the first gate electrode in a length direction thereof. A third region having a second conductivity type opposite the first conductivity type is arranged on or in the semiconductor film side by side with the second region in a width direction of the first gate electrode. The third region and the second region are in contact with each other and make a low resistance junction. A second gate electrode is formed on the gate insulating film along the second region. A fourth region having the first conductivity type is formed on or in the semiconductor film on an opposite side of the second region with respect to the second gate electrode. One of the first and the fourth regions is used as an output region according to a circuit operation.
