Abstract: PROBLEM TO BE SOLVED: To provide a storable and unfoldable framed structured that forms a planar framed structure from a rodlike folded state. SOLUTION: Ends of a plurality of outer frame members 11 to 16 are coupled zigzag to adjacent outer frame members 11 to 16 via hinges 21 to 25. A unfolding shaft is arranged. Support members are arranged respectively between the unfolding shaft and the plurality of hinges 21 to 25 located near to the unfolding shaft. One end of each of the support members 31 to 34 is angularly variably mounted on the unfolding shaft, and the other end of each of the support members 31 to 34 is angularly variably mounted on the related hinge. Wires 51 to 53 are arranged respectively between the unfolding shaft and the plurality of hinges located far from the unfolding shaft. An unfolding control mechanism tensions the wires 51 to 53 from the unfolding shaft to adjust the distance between the unfolding shaft and the plurality of hinges 21 to 25 located far from the unfolding shaft.

Abstract: PROBLEM TO BE SOLVED: To improve efficiency of a communication line and to reduce interference probability of a communication radio wave by setting time synchronization between a fixed station and a mobile station and the transmitting/receiving timings of the side of the fixed station, selecting one of the transmitting/ receiving timings of the side of the fixed station reported to the side of the mobile station and transmitting/receiving based on it to allow the mobile station to select the opposed station of communication. SOLUTION: The fixed station 101 communicates in two way with the mobile station 103 through the use of a receiving processing means 201 and a transmission processing means 202 based on a time reference maintained by a range and time reference synchronization maintaining means 200. The mobile station 103 communicates in two way with the fixed station 101 through the use of a receiving processing means 209 and a transmission processing means 208 based on a time reference maintained by a range and time reference synchronization maintaining means 207. A relay station 104 synchronize-maintains the time reference with a fixed main station 102 and provides a ranging radio wave 113 to the mobile station by a time reference synchronization maintaining means 205 and a ranging radio wave transmission processing means 204.

Abstract: PROBLEM TO BE SOLVED: To provide a connecting mechanism of a structural member connecting work is efficiently carried out, by giving selectivity of a connecting force to connecting sides of the structural member to be connected. SOLUTION: The connecting sides having inversion magnetic pole arrangement patterns are smoothly connected to each other, only in a case where positional relations of them are made to just coincide with each other. Therefore, the positioning and assembling of the structural member is easily carried out. When the positional relations of them coincide with each other and the connecting sides have different magnetic pole arrangement patterns from each other, the strong connecting force does not occur but the repulsion occurs. Accordingly, it is automatically determined that the sides should not be connected to each other, and resulting in preventing erroneous combination of the connecting sides of the structural member.

Abstract: PURPOSE:To perform alignment and holding fixture according to the bonding of a pair of hold bonding members by providing alignment means and hold fixing means on a pair of hold bonding members. CONSTITUTION:The taper face 101d of a holding side bonding member 100 is led to the center part gradually along the taper face 201a of the bonding member 200 of the side to be held according to the holding side bonding member 100 approaching to the bonding member 200 of the side to be held and simultaneously the projection part 111 of a rotation stopping means 110 is guided into a groove 112. A pair of hold bonding members 100, 200 are regulated at their approximate alignment in X, Y direction and the operation around Z axis at this time. Moreover, when both tapers 101d, 201a are bonded with the approach of the holding side bonding member 100 and the projection part 111 of the rotation stopping means 110 is bonded into the groove 112, a pair of the holding members 110, 200 are completely regulated around a Z shaft. When a driving motor 121 is driven in this state, two fingers 125 are moved to the external part mutually inside a holding face 201b to fix the Z axial direction.

Abstract: PROBLEM TO BE SOLVED: To provide a structure capable of being stored in a compact form and developed in space. SOLUTION: A hexagonal module M is constructed into a framed structure with beams 101 rigidly joined together. Twenty modules M are connected together in a predetermined pattern with joints J. The modules M of prismatic contour in a folded state are adapted to be developed in such procedures as to prevent the modules M from interfering with one another. In a developed process, the adjacent modules are connected and fixed to one another with couplers, and finally they become the space structure in a spherical shell form.

Abstract: PROBLEM TO BE SOLVED: To provide a structural unit of high versatility such that working efficiency can be greatly improved in terms of transportation, assembly and storage operations in outer space, a connected structure comprising a plurality of structural units combined, and a method of assembly and storage therefor. SOLUTION: First structural members A2 extend radially from approximately the mid points of the non-adjacent sides of a core member A1 to constitute a triaxial structural unit A. Each first structural member A2 is connected to the side of the core member A1 at its inner end via a connection A3. The outer end of each first structural member A2 is connected to the mid point of a second structural member A4 in an approximately orthogonal relationship. The structural unit A can be freely connected to another structural unit A via the second structural member A4 whereby connected structures of various shapes can be built. They can be compactly folded and stored through simple operations.

Abstract: PROBLEM TO BE SOLVED: To enable continuous communication in three specific areas on the earth and to enable continuous position measurement by always establishing a communication link for one satellite in three areas nearly directly below a remote point formed on the earth surface and enabling a communication between satellites above the areas. SOLUTION: A ground fixed station 203 sends and receives a control signal radio wave for communication line control to and from a satellite 201 above an area A. On satellites 201 and 202, repeaters which repeat and send radio waves from mobile stations to mobile stations and fixed stations are mounted. A satellite communication is made between the satellites 201 and 202, and a satellite above a 3rd area. Each satellite stays for about 6 hours within a range reaching a high latitude through an ascending node. Thus, three associative recursion type satellite groups have an ascending node latitude and an ascending node passing time of the heat satellites adjusted properly to constitute a hemisphere-limited type position measurement communication composite system which is capable of three-satellite position measurement.

Abstract: PURPOSE:To measure with high accuracy the position and attitude angle of an object to a moving body by obtaining the position and attitude angle on the basis of the detecting values of the position of a target of the object and the angle of the object when a still image of the object is photographed. CONSTITUTION:The image data of an object 9 to be measured including a target member 10 which is photographed by a TV camera 2 is processed in a signal processing part 3 and displayed at a display part 4. An operating part 5 is manipulated then to output a still image instructing signal to the processing part 3. As a result, a still image of the image data is displayed at the display part 4. A cursor 4a is sequentially adjusted to three targets of the member 10 via a cursor generating part 6 and the cursor positional data is output to an operating part 7. A joint angle of a manipulator 1 is detected by a joint angle detecting sensor 8 at the same time when the still image instructing signal is output. The joint angle data is output to the operating part 7. In the operating part 7, the position and attitude angle are operated from the cursor positional data, and the operated values are synthesized with the joint angle data. Accordingly, the position and attitude angle of the object 9 to the manipulator 1 are obtained.
