摘要： A surface acoustic wave motor utilizing ultrasonic vibration has an elastic member and piezoelectric elements for vibrating the elastic member. The motor is provided with a monitor voltage detecting circuit for detecting a monitor voltage generated by the vibration, from a portion of the piezoelectric elements not receiving the input voltage, and a frequency control circuit for controlling the input power supply frequency in such a manner that the monitor voltage assumes a predetermined value lower than a maximum monitor voltage obtained at the resonance frequency of the stator consisting of the elastic member and piezoelectric elements, in a frequency range higher than the resonance frequency.

摘要： The cooling system includes: a frame; a plurality of electronic devices disposed in the frame and operating or functioning independently from each other; fans disposed in the frame and supplying cooling air to the electronic devices; a temperature acquiring portion for acquiring the temperature of the cooling air; an air-flow resistance adjusting portion for adjusting the air-flow resistance to the cooling air; and a controller for controlling the fans and the each air-flow resistance adjusting portion. The controller determines each target cooling air volume required for cooling each electronic device to a predetermined temperature based on temperature information acquired by the temperature acquiring portion and heat generation information on each electronic device, controls each air-flow resistance adjusting portion to set the volume of cooling air to each target cooling air volume, and performs the drive control of the fans to set the volume of cooling air to the minimum necessary.

摘要： A user-friendly camera with a visual line detection system simplifies the operation by making manual selection possible for establishing an auto focus region directly without going through time consuming procedures, even when the camera is selecting an auto focus region based on visual line information. An auto selection mode, a visual line selection mode, and a manual selection mode are available for establishing an auto focus region with mode selection being made by an auto focus region switching system. When selection of the auto focus region is being executed in the visual line selection mode, signals from the auto focus region manual selection system may be entered so that the manual selection input takes priority and the intention of the photographer becomes the priority. The change of mode is temporarily executed easily during the visual line selection mode operation.
摘要翻译：具有可视线检测系统的用户友好型摄像机即使在摄像机基于视线信息选择自动对焦区域时，也可以通过手动选择可直接建立自动对焦区域而不经过耗时的操作来简化操作。自动选择模式，视线选择模式和手动选择模式可用于建立自动对焦区域，其中模式选择由自动聚焦区域切换系统进行。当在视线选择模式中执行自动聚焦区域的选择时，可以输入来自自动聚焦区域手动选择系统的信号，使得手动选择输入优先，并且摄影者的意图成为优先。在视线选择模式操作期间，模式的改变暂时执行。

摘要： A camera with a visual line position detection device capable of highly accurate determinations even when diopter adjustment is accomplished after initial completion of correction of the visual line position determining system. The camera includes a screen to form a subject image, a pentagonal prism provided inside the finder, a visual line position detection device equipped with a light emitting unit and a light receiving unit to detect the visual line position, and a diopter adjustment lens placed on the photographer's side of the pentagonal prism. The diopter adjustment lens is displaced after the correction of the visual line position detection device, and a correction coefficient needed to compute the visual line position on the screen obtained during the correction of the visual line position detection device is changed according to the displacement amount of the diopter adjustment lens.
