    摘要: A feeding system is provided for supplying a current to repeaters on a communication cable including a feed line for conducting a current to the repeaters. The feeding system includes a plurality of branching units provided on the communication cable and terminal stations each being connected through at least one of the repeaters to one of the branching units, and each of the terminal stations feeding a current through the feed line to the repeaters. In addition each of the plurality of branching units includes at least one switching circuit for switching to connect the at least one of the repeaters to the communication cable or to the ground, depending on the amount of current conducting through the feed line in the communication cable. Further, the current thresholds of the switching circuits in the plurality of branching units are preferably different from each other.

    摘要: An imaging apparatus of the invention comprises: an image pickup device for picking up object light; a mirror section for switching an optical path of the object light; a retaining member for retaining at least the mirror section; and a shake detection section for detecting a shake of the image pickup device, wherein the shake detection section is provided in a member separate from but indirectly connected to the retaining member via a predetermined connection section. The shake detection section is attached to the separate member connected indirectly to the retaining member that retains the mirror section and hence receives directly a vibration at the time of driving of the mirror section, with the intervention of the connection section. This avoids that the vibration caused by the driving of the mirror section is directly transmitted to the shake detection section. That is, the vibration is bypassed and damped along a route going through the connection section. This minimizes the influence on the shake detection in the shake detection section. As a result, a clear,photographed image is obtained on the basis of the shake correction.

    摘要: A camera, which is waterproof, having a relatively complicated three-dimensional configuration in which a cover thereof is constituted by a plurality of cover elements. A top cover 20, a front cover 30 and a side cover 40 are connected at the inside to form a first cover group. Then a main body 50 of the camera is connected to the first cover group to form a half completed body. A second cover group which is constituted by connecting a rear cover 60 to a bottom cover 70, and a lid 80, are connected to the half completed body. Each connection part therebetween has a rib and a groove corresponding to the rib. A packing is inserted into the groove to seal the groove and rib. Thus, a cover structure with a relatively complicated three-dimensional configuration as having a projecting grip, a pop-up flash, or the like, is possible to be made. At time of repair, for example, it is possible to get an access to the inner mechanisms of the camera, only by removing the second cover group from the camera body.

    摘要: A step-down switching regulator prevents an output voltage undershoot and enables a quick lowering of an output voltage immediately after turning off of power supply. The step-down switching regulator includes an NMOS transistor connected between an output terminal and a ground voltage and another NMOS transistor connected in parallel with a synchronous rectification transistor. Upon reception of an on/off signal for terminating the operation of the switching regulator, the NMOS transistors are turned on into an on-state.
