摘要:
An HDTV signal transmission system for sending a 10-bit-parallel YPbPr-format HDTV signal converted to ten C4 containers, and further to the SDH (a new synchronous digital network) STM-16 frame for transmission based on CCITT recommendations. The system includes a transmitter and receiver. The transmitter has time dividers for time-based dividing the HDTV signal into eight separated video signals, a C4 container device for multiplexing the eight separated video signals to ten C4 containers, and a STM-16 framing device for reformatting the ten C4 containers to the STM-16 frame. The receiver has an STM-16 deframing device for separating the ten C4 containers from the STM-16 frame, a C4 de-container device for demultiplexing the ten C4 containers to eight separated video signals, and time-division multiplexers for time-division multiplexing the separated video signals to the 10-bit-parallel YPbPr-format HDTV signal.

An optical fiber connection structure which reduces MPI in the use of an optical fiber with a bend resistance improved by forming holes in the fiber, and a single-mode fiber which reduces MPI are provided. A second cladding portion of a second single-mode fiber 20 includes holes 28, and thus, the second single-mode fiber 20 has low bending loss. A portion of the second single-mode fiber 20 connected to a first single-mode fiber 10a is made solid by filling corresponding portions of the holes 28 over the length L0, and light in a mode LP11 is significantly attenuated in this portion, thereby reducing MPI.

The invention relates to a vehicle suspension arm supporting structure. A receiving portion 9 is formed integrally on a subframe 5 which is formed of a light metal in such a manner as to extend transversely outwards, and a sheet steel member 15 is connected to the subframe 5 by a bolt or a nut in such a manner as to be situated below the receiving portion 9 of the subframe 5 at a predetermined interval. A base portion 13b of a suspension arm 13 is disposed between the receiving portion 9 of the subframe 5 and the sheet steel member 15, the base portion 13b of the suspension arm 13 is supported on the subframe 5 via a rubber bushing joint 14 by a connecting bolt 16 which vertically passes through the receiving portion 9 of the subframe 5 and the sheet steel member 15, and the receiving portion 9 of the subframe 5 is connected to a side member 4 by the connecting bolt 16.

A radiation imaging system is configured by a collimator 30A including a detector 21 with a discrete detection pixel corresponding with a pixel and a plurality of radiation passages 31 and looks into a plurality of detectors 21 through one radiation passage 31 to set a step width of rotation around a rotation center axis X1 only for an angle θp made by lines provided by connecting a center detector 21 of the radiation passage 31 and the adjacent two detectors 21. In the case of generating a flat plane projection image for one direction, radio-graphing is carried out on a projection image in a plurality of predetermined angle positions (−θp, 0, +θp) in the circumferential direction of the rotation center axis X1 and thereby one plane projection image is obtained.

In a suctioning state, even if the amount of dust trapped in a dust collecting unit in a main air passage is increased, air suctioned from a hose connection port is branched into a first half passage and reduction in the suction air amount can be suppressed. When the suctioning state is switched to a dust moving state by switch means, the dust trapped in a pleated filter is moved to the dust collecting unit, increase in the air passage resistance at the first half passage side caused by clogging of the pleated filter can be suppressed, and reduction in suction power over time can be suppressed. Since an upper air passage and lower air passage are provided in the lid body, the dust collecting unit is exposed with the lid body opened, whereby maintenance performance of the dust collecting unit is improved.
