Abstract: There is provided a video distribution system, a video distribution method, and a display terminal enabling more reliable video distribution, the video distribution system including: an image acquisition unit that acquires a low-resolution image from a low-resolution camera while acquiring a high-resolution image from a high-resolution camera; an abnormality determination unit that determines whether or not there is an abnormality in any one of a first signal representing the low-resolution image and a second signal representing the high-resolution image; and a transmission control unit that transmits first synthetic images to a display terminal in a case where it is determined that there is no abnormality, the first synthetic images having continuity between the low-resolution image and the high-resolution image, and transmits second synthetic images to the display terminal in a case where it is determined that there is an abnormality, the second synthetic images substantially reproducing continuity by repla

Abstract: A simplified tilt-integrated suspension mechanism includes first and second supporting legs to support an upper frame and a lower frame on one side of a seat section, and third and fourth supporting legs to support the lower frame and the upper frame on the other side of the seat section. The first and third supporting legs are pivotally connected to the upper frame on the same axial line. The second and fourth supporting legs each include a lower supporting leg portion pivotally connected to the lower frame, and an upper supporting leg portion pivotally connected to the lower supporting leg portion by a pivot pin and slidably joined to the upper frame. A releasable locking means may also be provided.

Abstract: A tilt-integrated suspension mechanism which is simplified in apparatus configuration is provided.

Abstract: A driving device which is automatically activated by detecting solar light and an automatic ventilation system utilizing the aforementioned driving device. An electric motor (21) is connected to relay switch (22), which is connected to limit switch (23) and light sensor switch (24). The limit switch (23) is connected between the relay switch (22) and the power supply and a manual main switch (25) between the light sensor switch (24) and the power supply. Normally when the main switch (25) is "on" and solar light exceeds the threshold, the light sensor detects it and the contact of the switch (24) changes to be activated. Electricity is then supplied to the relay switch (22) and the contact of the relay switch (22) also change to be activated. The electric motor is interlinked with a vent cover via the power transmission and the vent cover gradually begins to open.
