摘要： A piezoelectric film device has a piezoelectric film element and a power supply circuit. The piezoelectric film element is formed of a first electrode, a second electrode, and a piezoelectric film that is sandwiched between the first electrode and second electrode and has a polarization vector in the film thickness direction. The polarization vector is inverted by application of a predetermined voltage or higher through the first electrode and second electrode. The power supply circuit supplies voltage for inverting the polarization vector. The piezoelectric film has each different lattice constant depending on the direction of the polarization vector. The piezoelectric film device keeps a different displacement position corresponding to the direction of the polarization vector even when the voltage application is stopped.

摘要： A housing 2 for a vehicular transmission comprises a first room R1 which accommodates a continuous speed change mechanism and a second room R2 which accommodates a driving force transmission mechanism including a starting mechanism, a reduction train, a differential mechanism, a power supply mechanism for an oil pump, etc. In each room, inlet openings 72 through 74 for oil discharge passages are provided near and above both the sides of an oil pan 26 in the horizontal direction perpendicular to the input and output shafts of the continuous speed change mechanism, to return lubrication oil to the oil pan 26. Also, walls 61 through 65 are provided in the rooms to lead the lubrication oil into the respective inlet openings. In this construction, the lubrication oil returning from each room to the oil pan 26 is stabilized at each room and discharged to the oil pan 26, and thereby the lubrication oil achieves homogeneity in the oil pan 26.
