摘要： An optical receiver is disclosed, in which no additional photodiode to monitor the optical input level and no temperature control unit are necessary. The receiver of the invention provides an avalanche photodiode (APD) to receiver the first optical signal with the first wavelength and a PIN-PD to receive the second optical signal with the second wavelength. The optical input level for the APD is indirectly determined through the photocurrent generated by the PIN-PD and the bias voltage for the APD is so adjusted that the APD shows an optimum multiplication factor for the optical input level.

摘要： The material utilization efficiency of FPC's is improved, to provide a low cost touch panel. A touch panel 100 is constituted by: a rectangular transparent panel 104; and a plurality of light emitting elements 8a and a plurality of light receiving elements 8b provided at the peripheral portions of the transparent panel 104, for specifying the coordinates of targets of detection. An elongate FPC 106 is folded at a plurality of predetermined locations to be provided as a frame along the four sides 122a, 122b, 122c, and 122d of the transparent panel 104. The plurality of light emitting elements 8a are provided on the FPC 106 along two adjacent sides of the transparent panel 104, and the plurality of light receiving elements 8b are provided on the other two sides of the transparent panel 104 so as to face the light emitting elements 8a.
摘要翻译：提高FPC的材料利用效率，提供低成本的触摸屏。触摸面板100由矩形透明面板104构成; 以及设置在透明面板104的周边部分的多个发光元件8a和多个光接收元件8b，用于指定检测目标的坐标。细长的FPC106在多个预定位置被折叠，以沿着透明板104的四个侧面122a，122b，122c和122d设置为框架。多个发光元件8a被设置在透明面板104的两个相邻侧的FPC 106上，并且多个受光元件8b设置在透明面板104的另外两侧，以便面向发光元件8a。
