Patent number: 8001723Abstract: The present invention is to provide a technology capable of planting seedlings in soil in planting ground such as dry land and allowing the seedling to root securely and grow without artificially supplying water continuously. Not only is a seedling fixed inside an upper opening portion of a tube having a length to a deep water-containing layer in the planting ground but also a growing medium is put inside the tube at a hardness that allows the root of the seedling to grow long downward, and the root of the seedling is allowed to grow below the tube, thereby obtaining the seedling having a long root. A vertical hole having approximately the same diameter as that of the tube is dug in the ground of the planting ground until reaching a soil layer having water quality and water quantity necessary for growth of plant, the seedling having the long root is buried in the vertical hole together with the tube, thereby planting the seedling in the planting ground.Type: GrantFiled: February 10, 2006Date of Patent: August 23, 2011Assignee: Mitsubishi Heavy Industries, Inc.Inventors: Kazuhisa Tamura, Naoki Ogawa, Wataru Kawamura, Hiromitsu Nagayasu, Takehiko Matsui, Kinya Fujita, Masatoshi Tamai, Kenichi Katayama, Shinobu Inanaga

Publication number: 20070264100Abstract: To present a method of manufacturing a multipitch screw easily by using flat dies suited to mass production. A flat die 4 includes linear ordinary screw threads 40a, and multipitch screw threads 40b consecutive to the ordinary screw threads 40a, slightly shorter in height than the ordinary screw threads 40a, with both side walls formed alternately and consecutively, alternating between a section departing from the central line 40c of screw threads and an approaching section along a central line 40c, and symmetrically to the central line 40c of screw threads. After forming the tacks of a constant lead angle screw on the outer circumference of a shaft-like blank piece by the ordinary screw threads 40a, tracks of a multipitch screw are formed by the multipitch screw threads 40b, and therefore the tracks of a multipitch screw varying in the force applied at the time of rolling can be formed easily.Type: ApplicationFiled: November 7, 2004Publication date: November 15, 2007Applicant: NAGOYA INDUSTRIAL SCIENCE RESEARCH INSTITUTEInventors: Hiroshi Fujii, Naoki Sase, Kenichi Katayama, Yoshinori Moriguchi
