A multilayer piezoelectric device including a body having internal electrode layers and piezoelectric ceramic layers alternately stacked. The internal electrode layers contain Cu as a major component, the piezoelectric ceramic layers contain a compound oxide represented by Pb(Ti, Zr)O3 as a major component, and a metal oxide (Nb2O5, Sb2O5, Ta2O5, or WO3) containing Nb, Sb, Ta, or W, which is at least one of a pentavalent metal element and a hexavalent metal element, is incorporated in the piezoelectric ceramic layers such that the concentration of the metal oxide decreases with distance from the internal electrode layers. Thereby, even in a case where internal electrodes contain Cu as a major component, it is possible to provide a multilayer piezoelectric device which can be obtained by low-temperature firing while ensuring a sufficient piezoelectric constant.

A vehicle light control apparatus includes an illumination control unit for executing illumination control on the mode of illumination of a subject vehicle based on signal transmission of a vehicle ID signal unique to the subject vehicle and signal reception of the vehicle ID signal unique to the subject vehicle. The control unit identifies a vehicle having brightness exceeding a predetermined threshold from an image of other vehicles acquired through an image recognition MPU as a vehicle having an illumination adjustment failure, and returns the same vehicle identification signal transmitted from the other vehicle thus identified to vehicles other than the subject vehicle.

摘要:
It is an object of the present invention to provide a spinning device that detects early that fibers F have been accumulated in an air exhausting space 55 to prevent a defect (weak yarn) in a spun yarn. A spinning device in accordance with the present invention includes a pneumatic spinning nozzle 19, a whirling current generating chamber 25 in which fibers are twisted using a whirling air current generated by the pneumatic spinning nozzle, an air exhausting space 55 that is in communication with the whirling current generating chamber 25, a negative pressure source that sucks air from the air exhausting space 55, and a pressure sensor 63 that detects a pressure in the air exhausting space 55. When the pressure detected by the pressure sensor 63 during a spinning operation performed by the pneumatic spinning nozzle 19 rises to at least a predetermined value, the unit controller 32 performs control such that the spinning operation is stopped. The unit controller 32 further lights an alarm lamp 71.
