摘要:
It is an object of the invention to provide a camera control system in which operations intended by clients can be carried out by a camera server by appropriately managing and controlling every client that wishes to control a camera so that operation commands are issued to the camera server from only one client at any given time. In a camera control system composed of: a camera server 1 that controls a camera whose angle can be freely controlled; and a plurality of clients 3a, 3b, and 3c that control the camera and display images transmitted from the camera server 1 on a display screen, the camera server 1 includes notifying means operable when the camera server 1 has received a control authorization acquisition request for camera control that has been issued by one client to notify the client of time information including a waiting time before the camera control is possible and a permitted control time during which the camera control is permitted for a fixed period after the waiting time has elapsed.

A plurality of recesses are provided on a first main surface of an n-type semiconductor region of a semiconductor chip forming a constant voltage diode, and a p++-type semiconductor region is provided on the first main surface including inner faces of the plurality of recesses. Thereby, a portion of a depletion layer width with high voltage dependency and a portion thereof with low voltage dependency can be provided at a p-n junction portion of the constant voltage diode formed by the p++-type semiconductor region and the n-type semiconductor region. As a result, a leakage current can be reduced in a blocking state where a breakdown voltage of the p-n junction portion of the constant voltage diode is set to be low. Accordingly, a leakage current of a constant voltage diode can be lowered.

The object of the present invention is to provide an axle box suspension for a railway car with a simple structure to fix coil springs and support rubbers, and enabling easy mounting operation. Coil springs 21 and 22 are disposed on top of an axle box 10. Support rubbers 30 are disposed on front and rear portions of the axle box 10 with respect to the traveling direction of the railway car. A support shaft 31 is disposed at the axial center position of the support rubber 30, and the upper end of the support shaft 31 is passed through the side beam 6. The upper end of the support shaft 31 protruding from the upper surface of the side beam 6 is fixed via a nut. The operation of fixing the support shaft 31 to the side beam 6 by tightening the nut 40 can be performed at the upper surface area of the side beam 6, so the operation is facilitated.
