Patent number: 7380376Abstract: This invention relates to a non-slip structure, which is highly efficient in preventing a slip with no trouble caused by a through hole, thereby enhancing reliability. The non-slip structure of this invention is characterized in that a portion of a metal plate such as a steel plate and the like is sheared so as to form cutting lines (a pair of lateral side cutting lines and a joining cutting line) for forming a protruded piece and, at the same time, the protruded piece is pulled up along the cutting lines to a height, which does not exceed the thickness portion of the steel plate so as to raise the shearing surface (edge), so that the sheared surface does not form a gap nor any through hole in contacting the steel plate.Type: GrantFiled: October 16, 2002Date of Patent: June 3, 2008Assignee: Shin Caterpillar Mitsubishi Ltd.Inventors: Shunji Ohno, Norio Nakajima, Kazumichi Iwasa, Masanori Tsuji, Tsuyoshi Doi, Yoshihisa Kohzu, Yoshihiro Agarihama, Shinya Ura, Hideyuki Miyake

Patent number: 7263355Abstract: A test apparatus main body mounted in a single housing has a connection unit, a common bus, terminal control units, measurement units, and a total control unit. The connection unit can connect at least two terminals of identical or different type of communication systems. The terminal control units output test signals including signals that respectively control the terminals which can be connected to the connection unit based on predetermined test programs according to the type of communication systems, and measurement instructions, which are supplied via the common bus. The second measurement units perform measurements designated by the measurement instructions upon reception of response signals which are output from the terminals in response to the test signals from the terminal control units.Type: GrantFiled: June 10, 2004Date of Patent: August 28, 2007Assignee: Anritsu CorporationInventors: Takayuki Morikawa, Tsuyoshi Doi, Osamu Miyashita

Patent number: 7162839Abstract: The invention provides a slip stopper which achieves a great slip stopping effect, and can be used for a location where a problem occurs if a through hole is opened therein. In a protruding portion that protrudes from the upper surface of a steel plate in the plate thickness direction, a concave portion and drain channels, that lead to the steel plate upper surface from the concave portion, are formed. The inner surface of the concave portion and the groove side surfaces of drain channels are formed by shear planes which extend substantially perpendicular to the steel plate upper surface, and are obtained by half blanking that does not open a through hole in the steel plate.Type: GrantFiled: November 11, 2002Date of Patent: January 16, 2007Assignee: Shin Caterpillar Mitsubishi Ltd.Inventors: Shunji Ohno, Kazumichi Iwasa, Norio Nakajima, Masanori Tsuji, Tsuyoshi Doi, Yoshihisa Kouzu, Yoshihiro Agarihama, Shinya Ura, Hideyuki Miyake

Patent number: 7021109Abstract: An easy manufacturing method of a slip stopper, and apparatus therefor, that has a great slip stopping effect and can be used for a location where a problem occurs if a though hole is opened therein. After a protruding portion is formed on a steel plate, by using a first punching die unit, so as to protrude from the upper surface in a plate thickness direction, a concave portion and drain channels are formed in the protruding portion by shear planes that extend substantially perpendicular to the steel plate upper surface and have been half-blanked so as not to open a through hole in the steel plate by using a second punching die unit.Type: GrantFiled: November 11, 2002Date of Patent: April 4, 2006Assignee: Shin Caterpillar Mitsubishi Ltd.Inventors: Shunji Ohno, Kazumichi Iwasa, Norio Nakajima, Masanori Tsuji, Tsuyoshi Doi, Yoshihisa Kouzu, Hideyuki Miyake, Mamoru Sugimoto
