An electronic-data authentication method is for authenticating electronic data provided by a virtual person anonymously used on a network, performed by a virtual-person management system including a user terminal, a user management device, and a virtual-person management device. The method includes receiving, by the virtual-person management device, the electronic data, a first electronic signature generated by encrypting the electronic data with a first signature-creation key, and an virtual person ID for uniquely identifying the virtual person from the user terminal; authenticating, by the user management device, the first electronic signature received at the receiving by using a first signature-authentication key corresponding to the first signature-creation key; generating, by the virtual-person management device, a second electronic signature by encrypting the electronic data received at the receiving with a second signature-creation key issued for the virtual person; and transmitting, by the virtual-person management device, the second electronic signature to the user terminal.

A supporting portion is provided only at a winding start portion side and an outside of the other part of a deforming portion other than the winding start portion side is opened. Thus, adjacent spiral contactors can be arranged to be close to each other. Therefore, a mounting density of a spiral contactor on a guide frame can be increased. Further, since the deforming portion can be arranged at an opened region, a width of the deforming portion can be widened. As a result, the spiral contactor having a large spring constant is provided.

Object A connection board is provided in which multiple external contacts of an electronic component and multiple spiral contacts on a board are arranged to highly accurately face each other, and the external contacts are actively guided to the spiral contacts, so as to reliably provide individual connections therebetween.Solving Means A connection board CB includes a relay board 20 having a plurality of spiral contacts 24A, 24B provided on both surfaces of the relay board 20, and a guide member 30 having a plurality of small holes 31 into which the spiral contacts 24A and a plurality of external contacts 2a provided on an electronic component 1 are respectively inserted in both directions. The relay board 20 and the guide member 30 are arranged to face each other. Small holes 31A provided in at least two or more corner portions from among the plurality of small holes 31 have a diameter smaller than a diameter of the residual plurality of small holes 31. When the electronic component 1 is mounted, the external contacts 2a at the corner portions are positioned with the positioning small holes 31A at the corner portions. Hence, the external contacts 2a can be also positioned with respect to the residual small holes 31.

A connecting element includes a support member, a flexible substrate wrapped around the support member, and elastic contacts provided on the flexible substrate. A positioning hole is formed in the support member. A first positioning component is positioned and soldered on a metal layer formed on a motherboard, and a second positioning component is positioned and soldered on a metal layer formed on an electronic component. The first positioning component is inserted into the positioning hole in the connecting element, and the second positioning member is fitted to the first positioning component. Accordingly, the connecting element is positioned with respect to both the motherboard and the electronic component.

A substrate is formed with a plurality of spiral contactors on an upper surface serving as a first surface and a plurality of connecting terminals on a lower surface serving as a second surface. Since the spiral contactors are arranged in a matrix on the upper surface serving as the first surface, a lot of spiral contactors can be provided on the substrate of the present invention, and a mount area can be enlarged, and the size of the connector can be decreased.

A ground pattern that extends from a conductive portion of a through hole serving as a ground line is disposed in the vicinities of outer circumferences of through holes serving as signal lines. The thickness of a substrate for a connector in a Z direction is small and the lengths of the signal lines are short, such that favorable high-frequency characteristics can be obtained. Further, since only one of the through holes is sufficient to be used as the ground line, the remaining through holes can be used as signal lines. Therefore, the number of signal lines can be increased.

An IC card connector is provided with grounding terminal members, in which a pair of grounding terminal members has simple structure and common shape allowing a reduced cost and easy fabrication. The IC card connector is provided with a housing with a plurality of pin terminals, a frame mounted on the housing, a pair of guide sections are provided longitudinally at both side sections of the frame to remove and insert to IC card, and respective arm sections of grounding pieces. mounted on the guide sections. The IC card is inserted between the guide sections so that a grounding terminal of one side section of the IC card is made to come into contact with first expanded sections, while a grounding terminal of the other side section of the IC card is made to come into contact with second expanded sections.

A graphic editing apparatus makes it easy to change positions, shapes, or states of a graphic in a screen on a display unit with the passage of time or the change in value of an attribute, and then delineate the resultant graphic. The graphic editing apparatus comprises displaying units 17 and 18 for displaying graphics and time instants in a graphic area 24 and a time area 25 respectively on a graphic display unit, a processor 19 for specifying in graphic information an association between points on a change reference graphic 27 and points on a time graphic 28, and an updating unit 20 for performing interpolation to calculate the position of a point on the change reference graphic 27 with the movement of a current time point on the time graphic 28 or the passage of time, executing editing to move or deform the graphic according to the calculated position of the point, and displaying the graphic. The graphic editing apparatus handles an attribute value display graphic and a time-sequentially varying graphic, sets a bind point, displays grips, performs graphic relating-based editing, edits graphics synchronously, and so on.
