Abstract: PROBLEM TO BE SOLVED: To provide a lightweight, strong scaffolding board by mounting a carbon fiber reinforced resin board to the rear side of a part where a scaffold is positioned so that the orientation of the carbon fiber conforms to the longitudinal direction of the scaffolding board. SOLUTION: A CFRP resin board 2 is fixed to the rear side of a wood scaffolding board 1 through an adhesive 3. In the resin board 2, carbon fibers are oriented in one direction and solidified using a resin and the fibers are oriented in the longitudinal direction of the board 1. In order to provide the equivalent strength without providing the board 2, it is necessary to increase the thickness of the board 1 and hence the total weight may greatly increases; however, by providing the board 2, it is not necessary to increase the thickness of the board 1 so that an increase in weight can be avoided and reduction in weight is achieved and strength can be improved. And the number of the board 2 is not limited to one.  Thus reduction of weight and improved strength both can be achieved, and easy transportation, construction and removal can be achieved and reliability and safety can be improved.

Title: Sampling clock phase adjustment system
Inventor: AWATA YUTAKA
IPC: H04B3/06
Filed: 1988-03-23
Abstract: PURPOSE:To reduce the scale of circuit without widening the dynamic range of a post-stage echo canceller by providing a delay equalizer, a delay quantity detection section and a sampling clock phase adjustment circuit and making the sampling point of an echo canceller of the pre-stage and the post stage coincident. CONSTITUTION:A conventional multi-stage constitution echo canceller is provided with a delay equalizer 8, a delay quantity detection section 9 and a phase adjustment circuit 10. The pre-stage echo canceller 4 cancels the echo from the transmission at the leading of the clock, since the line equalizer 6 has a gain, the remaining echo cancel of the pre-stage echo canceller 4 is amplified and appears as the input to the post-stage echo canceller 5. Since the phase of the clock is deviated by the phase adjustment circuit 10 by the delay detected by the delay detection section 9 in the post-stage echo canceller 5, the echo is cancelled by a slight echo cancel quantity by making the sampling point coincident. Thus, the absolute width of the dynamic range of the post-stage echo canceller 5 is not required to be wide and the circuit scale is reduced.
