摘要:
Relative vector between an observation receiver located at an object and a reference receiver are divided into long period variation components not dependent on object displacements and short period variation components dependent on object displacements, and the short period variation component are represented by x, y and z axis components of unit vectors from the reference receiver toward the satellite. Then, carrier phases between at least three GPS satellites and the receivers are measured, and these measurement data are passed through a band pass filter to extract short period phase components corresponding to the short period variation components of the relative vectors. Next, at least three receiver to receiver single differences between the receivers and the GPS satellites are found for the short period phase components, and axial components of the short period variation components of the relative vectors are found by computation based on said at least three receiver to receiver single differences.

The present invention is a method for measuring a distance between a GPS receiver installed in a floating body and a GPS satellite, subjecting this measured distance data to a moving averaging process, removing from the measured distance data, distance data corresponding to a distance to a satellite orbit to determine a variance of the GPS receiver, removing wind wave-induced noise from the data, then determining three linear equations that use three-dimensional coordinates of the GPS receiver as unknown numbers, based on variances relative to GPS satellites and an azimuth and an elevation of each GPS satellite, and then solving these simultaneous equations to determine displacement of the GPS receiver corresponding to its variation component quantities on three-dimensional coordinate axes.

In building a house, it is necessary to arrange bearing walls and non-bearing walls in a well-balanced manner. However, in the case where a bearing wall is configured by fixing a plate-like body such as a bearing wall panel to the exterior-side face of a structural frame member formed by assembling horizontal members and pillar members into the shape of a square frame, the surface of the bearing wall panel protrudes from the face of the structural frame member on the exterior side by a distance corresponding to the thickness of the bearing wall panel. Thus, the exterior-side face of the bearing wall in which the bearing wall panel is provided is not flush with the exterior-side face of the non-bearing wall in which the bearing wall panel is not provided, and so there is a step. Accordingly, processing of the base during attachment of an exterior building material has been necessary. Furthermore, there has been a problem that in the case where the condition of the framework is to be inspected after building, the inspection cannot be performed unless the bearing wall panel is removed.Receiving members are fixed to inner side faces enclosed by structural members including pillars, studs, and horizontal members, of a building so as to allow a face of a bearing wall panel on the exterior side to be flush with faces of the structural members on the exterior side and a face of an adjacent non-bearing wall on the exterior side.

A connection tape (20) for connecting ends of square hole-punched carrier tapes (1) each of which comprises a carrier tape (11) formed with sprocket holes (11a) and pocket holes (11b), a top cover tape (12) and a bottom cover tape (13) attached on its top and bottom surfaces, respectively. The connection tape has a three-layer structure comprising a base tape (30), an adhesive tape (40) and a protection tape (50). The adhesive tape is composed of a first adhesive tape (41) which can adhere to the top cover tape, a second adhesive tape (42) which can adhere over the top of the sprocket holes in the carrier tape without interfering with the top cover tape, and a third adhesive tape (43) which can attach to the bottom cover tape. The second adhesive tape has sprocket holes (42a) which correspond to the sprocket holes in the square hole-punched carrier tape.

The present invention relates to a method for constructing a liquid crystal display, including a first step for connecting a first end part of a TAB film provided with a chip such as an LSI and an IC to an end part of a liquid crystal panel, and a second step for connecting a second end part of the TAB film to an end part of a printed board using solders, the end part of the printed board being formed to have projecting portions. According to the present method, prior to the second step, a tape is prepared, whose long side is cut to have projecting portions corresponding to the projecting portions of the end part of the printed board. Then, adhesive materials are thinly and evenly applied to a rear surface of each projecting portion of the tape. Thereafter, the tape is attached to the printed board so that the projecting portions of the tape may coincide with the projecting portions of the printed board and the adhesive materials may be applied to prescribed portions of the printed board. Next, the tape is removed from the printed board, leaving the adhesive materials on the prescribed portions of the printed board. Finally, the TAB film is arranged so as to be temporarily fixed to the printed board via the adhesive materials before being soldered thereto.
