Abstract: A mode adjustment system capable of changing interior in a conveyance with less effort and time includes an input device that allows an occupant to select mode information in which position information of a seat and a shade are registered in advance, a mode switching device that receives the mode information from the input device and switches the positions of the seat and the shade based on the mode information, a seat adjustment device, and a shade adjustment device. The mode switching device includes a seat movement amount calculator calculating the movement amount of the seat and a shade movement amount calculator calculating the movement amount of the shade, the seat adjustment device adjusts the position of the seat based on the calculated movement amount of the seat, and the shade adjustment device adjusts the position of the shade based on the calculated movement amount of the shade.

Abstract: An endoscope apparatus includes an endoscope insertion section and an optical adapter that is detachably attachable to the endoscope insertion section. In the optical adapter, an LED and a resistor for connection detection are connected in parallel to two electric contacts. In the endoscope insertion section, two signal lines are connected to electric contacts, which are connectable to the two electric contacts in the optical adapter. The endoscope apparatus includes an attachment-and-detachment determining power supply that is connected to one of the signal lines through a switching circuit, and an optical-adapter-attachment-and-detachment determining section. When connection of the optical adapter is detected, the switching circuit is switched to supply an electric current for turning on the LED from an LED turn-on power supply to the one of the signal lines.

Abstract: To provide an endoscope apparatus in which the number of signal lines inserted through an endoscope insertion section and the number of signal lines in an optical adapter are reduced to make it possible to reduce a diameter of the endoscope insertion section and reduce a size of the optical adapter. In an optical adapter 4 detachably attachable to a distal end portion of the endoscope insertion section, an LED 11 to which plural LED elements are connected in series and a resistor 12 for connection detection are connected in parallel to two electric contacts 14. To two signal lines 17a and 17b connected to electric contacts 15 connected to the two electric contacts 14, an attachment-and-detachment determining power supply 21 is connected through a switching circuit 18 and an optical-adapter-attachment-and-detachment determining section 24 is connected.

Abstract: An SDH transmission system including a container selection unit for selectively extracting a specific virtual container VC-m of a particular hierarchy from among the uppermost layer virtual containers VC-4 obtained from a demapping circuit that is a part of the SDH transmission system, and a path overhead processing unit for processing the path overhead of the specific virtual container VC-m obtained from the container selection means. Whereby, it is possible to extract and check the path overhead of the through path and to facilitate maintenance and inspection.

Abstract: A tributary interface, which performs interfacing between a high order transmission system and itself and includes a working tributary interface and a protection tributary interface as a pair for time slot interchanging with respect to the high order transmission system, is constructed so that the working tributary interface and the protection tributary interface can be operated independently. Thereby, in a time slot interchange unit of the SDH transmission system, the number of interfaces operable at a lower order side is temporarily increased so as to be able to cope with a request for temporarily increasing the number of interfaces from a user.
