Patent number: 10107623Abstract: Disclosed herein is an optical device that determines the central coordinates of a large-diameter cylindrical structure. The optical device has the function of calculating the central coordinates of a cylindrical structure using the coordinates of a reference point of the optical device, the coordinates of a survey point on the cylindrical structure seen on the optical axis of a telescope in a state where one of right and left reference marks (e.g., a vertical line) coincides with the edge of the cylindrical structure and the optical axis is positioned on the surface of the cylindrical structure, and an aperture angle between the optical axis and the reference mark.Type: GrantFiled: November 25, 2016Date of Patent: October 23, 2018Assignee: Kumonos CorporationInventor: Kazuhide Nakaniwa

Patent number: 8567731Abstract: An attaching means composed of a hole or a groove is formed in the leg of a tripod or another member attached to the legs. A support member inserted in the attaching means is so disposed as to extend in a direction from the attaching means to the ground, toward which direction the tripod is liable to overturn. Therefore, overturning of the tripod can be reliably prevented by a simple operation.Type: GrantFiled: June 2, 2009Date of Patent: October 29, 2013Assignees: Kansai Kouji Sokuryou Co., Ltd., Nishio Rent All Co., Ltd.Inventor: Kazuhide Nakaniwa

Patent number: 7667823Abstract: A device and a method for measuring the sizes of a remote object, for example, concrete crack, without using a high-place work vehicle or a ladder. An optical apparatus (e.g. a measuring device (10) ) used for this purpose is provided with a telescope (16) having a reticule plate (46) . The reticule plate (46) is provided with a plurality of reference scales (52) used for comparison with the size (W) of the image (C?) of an object (C) projected onto the reticule plate (46). The size of the object can be measured using the size of the object image measured with the reference scales (52) and a distance (a distance from a reference point P0 a to the object) measured with a distance measuring unit (20) of the optical apparatus.Type: GrantFiled: June 26, 2006Date of Patent: February 23, 2010Assignees: Kansai Kouji Sokuryou Co., Ltd.Inventor: Kazuhide Nakaniwa
