Patent number: 8952680Abstract: A magnetic sensor includes two sensor units with curved cores including meshing portions at front and base ends thereof and constructs a ring when the meshing portions mesh together. The meshing portions include main meshing portions that entirely overlap in a completely meshed state where the meshing portions overlap to the greatest extent. Auxiliary meshing portions that protrude inside and/or outside the ring are provided on the main meshing portions at the front and/or the base ends. In the completely meshed state, the auxiliary meshing portions do not overlap the main meshing portions or auxiliary meshing portions of the other core. In a non-completely meshed state where the main meshing portions partially do not overlap, the auxiliary meshing portions at least partially overlap the main meshing portions and/or auxiliary meshing portions of the other core.Type: GrantFiled: March 22, 2012Date of Patent: February 10, 2015Assignee: Hioki Denki Kabushiki KaishaInventors: Akihiro Nagai, Yoshinori Furuhata, Satoshi Imaizumi

Patent number: 7530277Abstract: A measuring apparatus has a display unit that can be favorably viewed when a measured object is clamped by a clamp-type sensor regardless of the orientation and position of the measured object. The measuring apparatus includes a first main unit on which the clamp-type sensor is disposed and a second main unit that is rotatably connected to the first main unit and on which the display unit is disposed. The second main unit is connected to the first main unit via a hinge unit capable of maintaining an arbitrary rotation position. The display unit is disposed on a surface of the second main unit that is opposite the first main unit when the measuring apparatus is folded up.Type: GrantFiled: January 29, 2007Date of Patent: May 12, 2009Assignee: Hioki Denki Kabushiki KaishaInventors: Takao Miyasaka, Akihiro Nagai, Yusaku Miyata, Tomoyuki Inoue
