摘要： An electronic apparatus is provided that comprises a shock detector for detecting a shock received by an electronic apparatus such as a portable telephone, a controller for comparing the value of the shock as detected by the shock detector with a reference value, and a memory element for storing an identifying signal generated when the value of a shock has exceeded the reference value and the value of shock. This enabling easy determination as to whether or not a breakdown has been caused by shock.

摘要： An angular velocity sensor includes a tuning-fork-shaped substrate (1), drivers (110) that are provided on the arms forming a tuning fork and vibrate the arms; monitors (150) for detecting vibrations generated by the drivers (110); and detectors (120) for detecting displacement of vibrations made in application of an angular velocity. The drivers (110), the monitors (150), and the detectors (120) are made of a lower electrode layer, a piezoelectric thin film, and an upper electrode layer formed on the arms. The outer peripheral edge of the piezoelectric thin film is shaped like a step having at least one flat portion. The flat portion along the outer peripheral edge has no upper electrode layer formed thereon. This structure prevents short circuits between the lower electrode layer and the upper electrode layer.

摘要： Protrusions made of an electrically conductive material such as a metal or ceramic are formed around a node point or a node line of vibrations of a piezoelectric plate on two principal planes thereof by a spraying process. The piezoelectric plate is held at the protrusions with leaf springs on the two principal planes. Thus, protrusions of a small surface area are formed without deteriorating the piezoelectric plate. The piezoelectric plate can be held stably without deteriorating the vibration characteristics. An alternating voltage is applied to electrodes of the piezoelectric plate through the electrically conductive protrusions. Because a spraying process is used, the protrusions can be thickly and precisely formed in a small area and held surely and reliably, with a good mechanical strength of the protrusions.
