Patent number: 7404692Abstract: Waves are amplified by a gradual decrease in depth, and when the waves reach a vertical wall 10 of a reef 2, breaking waves are generated by sudden decrease of the water depth. As the breaking waves rush into the upper portion of the reef 2 and pass through the slant slits 14, wave energy is absorbed by the reef 2 and the seat water returns back to the ocean through an opening 11. The sand brought into a reef 2 with the waves are washed away by the return flow 11 so that the sand is not deposited within the reef 2 and the space in the reef 2 is always clear. The return flow promotes generation of the breaking waves. The breaking waves are introduced into the slits, beach erosion is prevented, and a calm sea area utilized for marine leisure is created. The seawater in the reef, with sufficient air, flows to the sea area behind the breakwater through the paths 19.Type: GrantFiled: May 23, 2001Date of Patent: July 29, 2008Assignee: Nishimatsu Construction Co., Ltd.Inventors: Tadashi Fukumoto, Tsuyoshi Hashimoto

Patent number: 6798527Abstract: An object of the present invention is to provide a method for accurately measuring a three-dimensional shape of a measuring subject independent of the surface shape of the measuring subject, and another object thereof is to shorten the time from the measurements of the measuring subject until three-dimensional shape data is obtained so as to carry out efficient measuring operations. In a three-dimensional measuring system 1 that measures a three-dimensional shape of a measuring subject, two three-dimensional measuring devices 10, 20 are placed. The three-dimensional measuring device 10 measures a measuring subject placed in a measuring space 3 by allowing a laser slit light L1 in a longitudinal direction to scan in a lateral direction. Moreover, the three-dimensional measuring device 20 measures the measuring subject placed in a measuring space 3 by allowing the laser slit light L1 in a lateral direction to scan in a longitudinal direction.Type: GrantFiled: April 24, 2002Date of Patent: September 28, 2004Assignee: Minolta Co., Ltd.Inventors: Tadashi Fukumoto, Shigeru Osaki, Masahiro Ariizumi, Norio Matsunaga, Yoshihisa Abe

After introducing n-type impurities into the n-channel region and p-type impurities into the p-channel region, a silicon gate electrode is formed in such a manner that its width is enlarged only in the boundary portion between the n-channel region and the p-channel region. After forming a side wall insulating film, an n-channel diffusion layer and a p-channel diffusion layer, a metal silicide layer is formed in a self-aligned manner on the surfaces of the silicon gate electrode, the n-channel diffusion layer and the p-channel diffusion layer.Type: GrantFiled: August 31, 2000Date of Patent: May 27, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masahiro Yasumi, Ichirou Matsuo, Toshiki Yabu, Mizuki Segawa, Kunitoshi Aono, Akihiko Ohtani, Takayuki Minemaru, Tadashi Fukumoto

Patent number: 6529280Abstract: This invention is related to a three-dimensional measuring device for measuring three-dimensional positions of an objects. The three-dimensional measuring device comprises an optical projection system and an optical reception system. In a preliminary measurement prior to an actual measurement, the optical projection system projects slit light beam on the object with varying projection angle with in a narrow range, and the optical reception system receives the slit light beam reflected by the object and generates image signals corresponding to an amount of the received light synchronously with variation of the projection angle. Measurement conditions including intensity of the light beam and the projection angle for the actual measurement are set in accordance with the image signals of the actual measurement. Under the measurement conditions, the actual measurement is executed by projection the light beam on the object with varying the projection angle within a wide range.Type: GrantFiled: October 2, 2000Date of Patent: March 4, 2003Assignee: Minolta Co., Ltd.Inventors: Akira Yahashi, Toshio Norita, Eiro Fujii, Fumiya Yagi, Satoru Hirose, Takuto Joko, Makoto Miyazaki, Tadashi Fukumoto, Hideki Tanabe, Yoshiko Sakagawa
