    • PROBLEM TO BE SOLVED: To provide a transmission path characteristic estimate apparatus capable of estimating a transmission path characteristic in a wireless system adopting the OFDM system with high accuracy by following temporal variations in the characteristic without causing deterioration in the transmission efficiency.
      SOLUTION: The transmission path characteristic estimate apparatus is provided with: an equalization section 6 for correcting a received signal on the basis of transmission path characteristic data B; a demodulation section 8 for demodulating the received signal after the correction; a modulation section 10 for modulating data after the demodulation; a divider circuit 16 for calculating first transmission path characteristic data on the basis of known pilot data when receiving received pilot data on one hand, or calculating second transmission path characteristic data on the basis of user data in transmission units after modulation corresponding to the user data in the transmission units when receiving the user data in the transmission units on the other hand; and a filtering section 18 for eliminating a noise component from the calculated transmission path characteristic data A and outputting the result to the equalization section 6.

    • PROBLEM TO BE SOLVED: To provide a camera filter unit with reduced dimensions of a filter frame for holding an optical filter in an optical axis direction. SOLUTION: The camera filter unit 1 includes the filter frame 2, a filter-holding ring 3 and the optical filter 4. The optical filter 4 is fixed to an internal side of the filter-holding ring 3 while being held from the front and the rear between a protuberance 31 formed in the filter-holding ring 3 and a caulking part 33a. The filter-holding ring 3 is fixed to the internal side of the filter frame 2 by a ring-side male thread 32 on an outer peripheral surface which is screwed into a female thread 22 on an inner peripheral surface of the filter frame 2. The filter frame 2, the filter-holding ring 3 for fixing the optical filter 4 to the filter frame 2 and the optical filter 4 are arranged concentrically, thereby the front-and-rear dimension of the filter frame 2 can be made smaller than when the filter-holding ring 3 and the optical filter 4 are arranged while being not exposed from the filter frame 2.

    • PROBLEM TO BE SOLVED: To obtain artificial soil by reusing and recycling old clothing through not a conventional burning disposal bringing together generation of carbon dioxide but a disposal method of a resource-reusing type generating no harmful waste such as carbon dioxide and giving no load on the environment on disposing of a large amount of old clothing.
      SOLUTION: The artificial soil is obtained by using as the main material scrapped old clothing and mixing therewith at least one kind selected from wood chip, chaff and sludge. Alternatively, the artificial soil is obtained by using as the main material scrapped old clothing and kneading together therewith at least one kind selected from wood chip, chaff and sludge, and water followed by leaving the resultant product at rest. The raising seedling bed is obtained by putting either one kind of the artificial soil into the aqueous solution of an adhesive substance followed by stirring and straining, and drying the resultant product. Alternatively, the raising seedling bed is obtained by putting either one kind of the artificial soil and plant seeds into the aqueous solution of the adhesive substance followed by stirring and straining, and drying the resultant product.
