Abstract: A tap is designed so that the pollution of the environment can be prevented and the cleaning can be simplified. The tap includes an intake hole having openings at a screw portion of the tap. Air intake is performed through the intake hole, so that the chips generated by the screw portion in the cutting can be aspirated from the openings forcibly. Because the chips can be discharged without using cutting fluids, pollution of the environment can be prevented. Because the chips can be aspirated from the openings and discharged from the intake hole of the tap, the chips are not scattered on the work piece, and thus a cleaning process of the work piece can be simplified.

Abstract: Switching TFTs are controlled to a conducting state and a switching TFT to a non-conducting state, to provide a potential according to a threshold voltage to a gate terminal of a driving TFT. Then, in at least one embodiment, with the TFT maintaining the conducting state, a potential of a data line Sj is changed from a reference potential Vpc to a data potential Vdata to place the TFT in a conducting state. At this time, a current Ia flows and thus the gate terminal potential of the TFT rises. The higher the mobility of the TFT, the larger the amount of change in gate terminal potential and the smaller the current flowing through an organic EL element upon light emission. By this, a current that is not affected by variations in the threshold voltage of the TFT nor by variations in the mobility of the TFT flows through the organic EL element. Thus, in a current-driven type display device, variations in both the threshold voltage and mobility of a drive element are compensated for.

Abstract: An end mill is designed to reduce an amount of cutting fluids to prevent the environmental pollution. Because the end mill includes openings which open along spiral grooves, and the openings communicate with an aperture on the rear end surface of a shank via an intake path, chips generated through the cutting process are aspirated forcibly from the openings when air intake is performed via the intake path, and the aspirated chips can be discharged from the aperture on the rear end surface of the shank. As a result, because the usage of the cutting fluids for discharging the chips can be reduced or minimized in comparison with the conventional technologies, environmental pollution can be prevented.
