Abstract: The mobile communication terminal 1 and the image photographing apparatus 2 are connected through wireless communications 3 or optical communications 3, where the image data from the image photographing apparatus 2 is displayed in the display part of the mobile communication terminal 1 on a real-time basis, and various functions are controlled such as ON function, OFF function, a connection ON function, a connection OFF function, a recording start function, a recording stop function, a shuttering function, a flash function, a zooming function, an image size changing function, a monitoring function (a monitoring start function and a monitoring stop function), and an angle changing function and so forth, of the image photographing apparatus 2 on the basis of the control instructing data from the mobile communication terminal 1.

Abstract: A light detection device which can be stably surface-mounted on, for example, a circuit board or the like, and a mounting method thereof are provided. A light-receiving element includes, a transparent conductive electrode (first electrode), a semiconductor layer, and an electrode (first electrode), which are sequentially laminated on a transparent substrate. An insulative substrate includes a terminal electrode (second electrode) which is provided to be exposed at first and second faces of the insulative substrate. The light-receiving element is disposed at the first face of the insulative substrate, and the transparent conductive electrode and the electrode are electrically connected with the terminal electrode exposed at the first face of the insulative substrate. Hence, the light detection device with this structure is surface-mounted on the circuit board such that the terminal electrode exposed at the second face of the insulative substrate connects with an external terminal of the circuit board.

Abstract: The slope detecting device includes means for detecting a horizontal acceleration of the vehicle; means for detecting perpendicular acceleration to the running direction of the horizontal detecting means; and means for detecting, relatively to the horizontal detecting means and perpendicular detecting means, the acceleration-deceleration of the moving object by whether the sum of squares respectively which the acceleration detected by the horizontal detecting means and the acceleration detected by the perpendicular detecting means is equal to the second power of gravity acceleration, and calculating the slope of the vehicle in acceleration-deceleration so that it can detect the slope of vehicle in acceleration-deceleration as well as during running the vehicles at a constant speed.
