摘要： Provided is a driving device having an electromechanical transducer, a driving member, a moving member and a driving circuit. The driving circuit outputs a driving voltage at a frequency lower than that where the driving speed of the moving member is at maximum, and changes the drive frequency of the driving voltage so that the drive frequency has a negative correlative relationship with the ambient ten aperature. The change rate of the drive frequency to a change of the ambient temperature in the negative correlative relationship is larger than a change rate of a frequency where the driving speed of the moving member is at maximum to an increase of the ambient temperature, and the change rate permits the driving speed of the moving member to increase when the ambient temperature increases.

摘要： There is disclosed a semiconductor device having first and second semiconductor chips. The first semiconductor chip has a memory circuit. The second semiconductor chip has a circuit controlling the memory circuit. The contour size of the semiconductor device is reduced down to a smaller size required by a client without impairing the testability of the first semiconductor chip having the memory circuit. The circuit controlling the memory circuit consists of an MPU. The memory circuit consists of an SDRAM. The two semiconductor chips are stacked on top of each other over the top surface of an interconnect substrate. The chips are sealed in a molding resin, thus forming an SiP (System-in-Package). First terminals electrically connected with the second chip are arranged as external terminals of the SiP on the outer periphery of the bottom surface of the interconnect substrate. Plural second electrodes electrically connected with interconnects, which electrically connect the two chips, are mounted as terminals for testing of the SDRAM. The second electrodes are located more inwardly than the innermost row of the first external electrodes on the bottom surface of the interconnect substrate.

摘要： A robot apparatus is operable in a Cartesian coordinate system for moving a workpiece gripped by a hand thereof. The robot apparatus includes a self-propelled X-axis slide unit movably mounted on an X-axis rail unit extending in the direction of the X-axis of the Cartesian coordinate system. A Y-axis slide unit extending in the Y-axis direction normal to the X-axis direction has one end fixed to the X-axis slide unit. A self-propelled Z-axis slide unit is movably mounted on the Y-axis slide unit, and a slide base to which the robot hand is attached is mounted on the Z-axis slide unit. Lead wires connected to drive mechanisms for driving the X-axis slide unit, the Y-axis slide unit, and the Z-axis slide unit pass through case members, and are housed in the X-axis rail unit and connected to a terminal box secured to an end of the X-axis rail unit. The X-axis, Y-axis, and Z-axis slide units are prevented from interfering with the respective tracks of other units during operation of the robot apparatus, so that the working envelope of the robot apparatus can be increased.
