Abstract: PURPOSE:To obtain an AD converting circuit which hardware scale is minimized, by using an AD converter which word length is shorter than a desired word length at a frequency which is (L) times larger than a desired sampling frequency and processing it by supplying the output of the AD converter to a digital filter. CONSTITUTION:An analog signal is inputted into an AD converter 3 after it is limited in terms of band at an LPF2. The converter 3 performs AD conversion of a word length B which is shorter than a desired word length (B+alpha) at a frequency fh which is (L) times larger than a desired sampling frequency fs and inputs the output into a shift resister 4 which shifts at the clock of the frequency fh. Outputs of each tap introduced from the register 4 are supplied to a latch 5 which operates at the clock of the frequency fs and the output of the latch 5 is supplied to a multiplier 6 where the output is multiplied by a prescribed weighting coefficient. The output of the multiplier 6 is added at an adder and digital data of the word length (B+alpha) bit are outputted from a terminal 8. Since the multiplying and adding calculation of a digital filter composed of the register 4, multiplier 6, and adder 7 is performed with the sampling frequency fs, data rate is reduced to 1/L.

Abstract: PURPOSE:To obtain a roofing tile, which enables a pressing load to be easily absorbed further improves durability, by forming the roofing tile into a tapered shape in a manner wherein its thickness is larger in a working part side and smaller in an overlapping part side. CONSTITUTION:In the case of a roofing tile 1 of asbestos slate or the like overlapped with each other, the roofing tile 1 is formed into a tapered shape from the bottom end to the upper end so as to obtain its thickness larger in a side of an exposed working part 8 while smaller in a side of an overlapping part 7. Thus because a clearance S, formed by a reverse surface of the overlapping part 7 and a roof board 9, is narrowed further with the overlapping part 7 thin and flexible, a pressing load, acting on the roofing tile 1, can be well absorbed, while because the working part side 8 is formed in large thickness, durability can be improved against exposure of sunrays or the like and corrosion by rainwater or the like.
