摘要： An organic electroluminescent device contains an anode, a cathode, and an organic layer containing at least one luminous layer. The organic layer is disposed between the anode and the cathode. At least one luminous layer contains a π-conjugated compound exhibiting no overlap between the electron density distributions of the HOMO and the LUMO in the molecule, such that electron transition between the HOMO and the LUMO occurs by a through-space interaction in the molecule. The π-conjugated compound has a π-conjugated aromatic ring at a moiety on which at least one of the HOMO and the LUMO is localized.

摘要： A drive unit being characterized in that a movable object can be prevented from being tilted when the movable object is stopped using a restricting member. The drive unit comprises a piezoelectric element, a rod provided at an end of the piezoelectric element, a movable object frictionally engaged with the rod, and drive pulse generating means that apply drive signals to the piezoelectric element. The drive pulse generating means apply to the piezoelectric element a rectangular wave drive signal that has a duty ratio other than 0.5 and vibrates the rod so that a difference occurs between the expansion and contraction of the rod when the movable object is moved, and apply to the piezoelectric element a rectangular wave drive signal that has a duty ratio of 0.5 and vibrates the rod so that the movable object is not moved substantially when it is detected that the movable object is in contact with a restricting member.

摘要： A drive unit being characterized in that a movable object can be prevented from being tilted when the movable object is stopped using a restricting member. The drive unit comprises a piezoelectric element; a rod provided at an end of the piezoelectric element; a movable object, which is frictionally engaged with the rod and the movable range of which is restricted using the restricting members; and drive pulse generating means for applying drive signals to the piezoelectric element, wherein the drive pulse generating means apply a first wave drive signal for vibrating the rod so that the movable object moves toward the restricting member when the movable object is moved to a position where the movable object is close to the restricting member, and temporarily apply a second wave drive signal for vibrating the rod so that the movable object is moved in a direction of movement away from the restricting member after the movable object is made contact with the restricting member, and then stop the application of the drive signal.
