    • A viewfinder display apparatus which can realize superimpose having good visibility without giving uncomfortable feeling to a photographer is disclosed. The viewfinder display apparatus includes an eyepiece lens unit, an a member on which illumination unit which irradiates illumination light, and a plurality of region display sections arranged in a viewfinder optical path respectively to correspond to the focus detection regions. Each of the region display sections includes an outer frame which partially transmits light from an object to display edges of the focus detection regions in the viewfinder field and reflecting region in which reflecting surface which reflects illumination light from the illumination unit to guide the reflected light to the eyepiece lens unit are formed.
    • 公开了一种可以实现具有良好的可见度的叠加的取景器显示装置,而不给摄影者带来不舒服的感觉。 取景器显示装置包括目镜透镜单元,照射照明光的照明单元的部件和分别对应于焦点检测区域的取景器光路中的多个区域显示部。 每个区域显示部分包括:外框,其部分地透射来自物体的光,以在取景器场中显示焦点检测区域的边缘;反射区域,其中反射表面反射来自照明单元的照明光,以将反射光引导到 形成目镜透镜单元。

    • An integrated circuit includes a high-frequency power amplifier and a matching circuit. The high-frequency power amplifier has at least one stage of an amplifier element. The matching circuit has a MOSFET and a detector diode. The source of the MOSFET is connected to an input of a first stage amplifier element, the drain is connected to a ground, and the gate is also connected to the ground. A capacitor is connected between the gate of the MOSFET and the ground. The detector diode is connected in parallel between the drain and the gate of the MOSFET. Turning on the MOSFET reduces the effective gain of the first stage amplifier element, thereby allowing mode change.
    • 集成电路包括高频功率放大器和匹配电路。 高频功率放大器具有放大器元件的至少一个级。 匹配电路具有MOSFET和检测二极管。 MOSFET的源极连接到第一级放大器元件的输入端,漏极连接到地,栅极也连接到地。 电容器连接在MOSFET的栅极和地之间。 检测器二极管并联连接在MOSFET的漏极和栅极之间。 导通MOSFET会降低第一级放大器元件的有效增益,从而允许模式更改。
