Title: Rush transplanter
Inventor: FUJIMOTO SEIGO
IPC: A01C11/02
Filed: 1989-07-17
Abstract: PURPOSE:To prevent the damage of the buds of a rush seedling and improve the germination degree of the seedling after transplanted, by disposing feed rollers in such a state as to successively narrow the nipping intervals between the feed rollers in the feeding direction and also as to reduce the longitudinal intervals of the feed rollers in an extent capable of transferring the seedlings. CONSTITUTION:When a riding type traffic vehicle is moved forwardly and the seedlings of rush are fed into a feed shoot 18, the stem portion of the seedling is held with the wide portions of guide levers 17 from both the sides of the seedling. In each feed passageway 16, the root portion of the seedling is compressed with the right and left first feed rollers and simultaneously fed out. Since the interval between the second feed rollers 14 and 14 is narrower than that between the first feed rollers 13 and 13, the root portion is further compressed. Since the peripheral speeds of the second feed rollers 14 and 14 are larger than those of the first rollers 13 and 13 and the peripheral speed of the right feed roller 14 is larger than that of the left feed roller 14, the root portion of the seedling is elongated and further compressed with the right and left second feed rollers 14 and 14. The root portion is compressed and thinned with the third feed rollers 15 and 15 in turn in three stages and gradually elongated in a belt-like shape without damaging the bud of the seedling.

Title: Method and device for detecting magnetization
Inventor: KATAGIRI YOSHIMASA
IPC: G01R33/12
Filed: 1989-07-17
Abstract: PURPOSE:To detect magnetization with a high sensitivity by disposing an objective magnetized medium and a reference magnetized film to a semiconductor quantum well laser to constitute an external resonance laser and detecting the direction of the magnetization by the oscillation and non-oscillation of the laser. CONSTITUTION:The current density to be implanted to the semiconductor quantum well laser 1 is set larger than the threshold current for the laser 1 to oscillate when the direction of the magnetization of the reference magnetized film 2 and the direction of the magnetization of the objective magnetized medium 3 are reverse. The magnetized medium 3 is rotated around its shaft of rotation while a prescribed spacing to an air floating slider 6 is maintained and the the air floating slider 6 is swept relative to the magnetized medium 3, then if the direction of the magnetization of the magnetized medium 3 is reverse from the direction of the magnetization of the reference magnetized film 2, the laser 1 oscillates. The direction of the magnetization of the magnetized medium 3 is, therefore, detected with the high sensitivity if the oscillation and non-oscillation of the laser 1 are detected by a photodetector 5.

Filed: 1993-06-29
Abstract: PURPOSE:To minimize resistivity of a conductive line in high frequency by pressing a baked conductive pattern which has been formed by baking together with a substrate, an unbaked conductive pattern comprising a conductive paste formed on the substrate. CONSTITUTION:First, an unbaked conductive pattern 14 comprising a conductive paste is formed on an alumina substrate 12 by screen printing.
