Title: Method for seeding interrow space of crop in cold district and apparatus for the same
Inventor: ITO NOBUO
IPC: A01C7/00
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a method for seeding an interrow space of a crop, making it possible that a two-crop system is realized in a district, a place or a kind of the crop to which conventional two-crop systems cannot be applied, e.g. in a cold district, by conducting right timed seeding of a succeeding crop in the interrow space of a standing crop now cultured. SOLUTION: In this method for seeding the interrow space of the crop, the right timed seeding of the succeeding crop is conducted in the interrow space of the standing crop now cultured in the cold district by overlapping a time for right harvesting of the standing crop with a time for the right seeding of the succeeding crop, so that the two-crop system in the cold district can be realized. Further, the standing crop is harvested by a harvesting machine and the succeeding crop is seeded by a seeding machine 1. When the succeeding crop is seeded, seeding intervals are set so that the harvesting machine never tread nursery plants which are budding after seeding and multi-row seeding can be conducted in the interrow space, by considering the width and wheelbase of a traveling equipment of the harvesting machine.  In the seeding machine 1, its minimum ground clearance is set so that the seeding machine 1 never damages the standing crop by straddling the crop during the seeding operation.

Title: Moving image processing unit, moving image processing method, and moving image processing program
Inventor: ISHIKAWA MASAKI
IPC: H04N19/50
Filed: 2001-03-09
Abstract: PROBLEM TO BE SOLVED: To reduce a data quantity to be encoding-processed in encoding a moving image. SOLUTION: When encoding data to reproduce a moving image including a 1st image and a 2nd image after the 1st image and outputting the encoded data, a difference calculation section 11 obtains a difference between the 1st image and the 2nd image. A motion block extract section 12 extracts a motion block whose difference obtained by the difference calculation section 11 exceeds a prescribed threshold value. Then a data output section 13 encodes data as to the motion block in succession to data as to the 1st image and provides an output. Thus, synthesizing the data as to the 1st image with the data as to the motion block can reproduce a moving image. Thus, since a background part or the like without a motion is omitted and only a part with a motion is encoded and outputted, the data quantity to be encoded can be reduced.

Title: Manufacturing method of corrugate fin
Inventor: MORIHIRA SHINICHI
IPC: B21D13/00
Filed: 2001-03-12
Abstract: PROBLEM TO BE SOLVED: To improve the finishing dimensional accuracy of a corrugate fin even when the metal fin has relatively high hardness. SOLUTION: By annealing a strip work W after finishing a press step, the residual stress generated in the strip work W is removed, and a shrinking step is performed thereafter. Since a hardened part by the work hardening (in particular, a bent part 121) can be softened, the strip work W after finishing the press step can be easily shrunk, the radius of curvature of the bent part 121 can be reduced to the predetermined dimension, and the finish dimensional accuracy of the fin 120 can be improved even when the metal (stainless steel) fin 120 has relatively high hardness.
