    • A camera having a television mode has a shutter unit for opening and closing a plurality of shutter blades used as a shutter and a diaphragm by rotating a step motor in normal and reverse directions; a photometric device for performing a photometric operation with respect to a photographed object; a mode switching device for selectively switching a television mode for photographing a picture image on a television screen and a normal mode for performing a normal photographing operation; a trigger switch for outputting an open signal in synchronization with an operation for opening the shutter blades and outputting a closed signal in synchronization with an operation for closing the shutter blades; and a calculator for calculating an exposure amount by photometric information provided by the photometric device when the normal photographing mode is selected by the mode switching device. The calculator converts the calculated exposure amount to a time from a generating time point of the open signal of the trigger switch to a time point of the reverse rotation of the step motor so as to control a program exposing operation with respect to the shutter unit. The calculator calculates the exposure amount by the photometric information provided by the photometric device when the television mode is selected.
    • 具有电视模式的相机具有快门单元,用于打开和关闭用作快门的快门叶片和通过沿正向和反向旋转步进马达的振动膜; 用于对拍摄对象进行测光操作的测光装置; 模式切换装置,用于选择性地切换用于拍摄电视屏幕上的图像的电视模式和用于执行正常拍摄操作的正常模式; 用于与用于打开快门叶片的操作同步地输出打开信号并与用于关闭快门叶片的操作同步地输出闭合信号的触发开关; 以及计算器,用于当通过模式切换装置选择正常拍摄模式时,通过由测光装置提供的测光信息来计算曝光量。 计算器将计算的曝光量转换为从触发开关的打开信号的生成时间点到步进电机的反转的时间点的时间,以便控制相对于快门单元的程序曝光操作。 当选择电视模式时,计算器通过由测光装置提供的测光信息计算曝光量。

    • An active vibratory noise control apparatus reduces vibratory noise which is produced in the passenger compartment of a vehicle based on vibratory noise generated by a variable-cylinder internal combustion engine that can selectively be operated in a full-cylinder operation mode in which all of the cylinders are operated and a partial-cylinder operation mode in which some of the cylinders are out of operation. The active vibratory noise control apparatus has a partial-cylinder operation mode determining circuit for determining whether the variable-cylinder internal combustion engine is in the partial-cylinder operation mode or not. Depending on a determined result from the partial-cylinder operation mode determining circuit, a transistor is turned on or off to switch an amplifying circuit which drives a speaker into and out of operation.

    • In an active noise cancellation system having an adaptive filter that outputs a control signal, first and second speakers that emit a canceling signal generated based on the control signal, a microphone that detects an error signal, a correction filter that corrects the base signal by a correction value to generate a reference signal and a filter coefficient updater that successively updates the adaptive filter coefficient based on the error signal and reference signal such that the error signal is minimized, the correction value of the correction filter is set to a sum obtained by adding the transfer characteristic from the first speaker to the microphone, and a product obtained by multiplying the transfer characteristic from the second speaker to the microphone by the prescribed value, thereby enabling to reduce the number of microphones and avoid the increase in parts, the amount of work to provide complicated wiring to the microphones, and the computational load involved in updating the adaptive filter coefficient, while enabling to maintain an area in which noise can be reduced to the same level as that obtained before reducing the number of microphones.
