To provide a design assistance system, a design assistance program, and a design assistance method which are capable of reducing or eliminating the burden on a designer of a structure when designing the structure. A design assistance systemincludes an object recognizing unitand an interference determining unit. The object recognizing unitrecognizes an object existence area which is an existence area of a different object Afrom the structure Aon a three-dimensional coordinate system in accordance with information including the position of the object Aon the three-dimensional coordinate system which has been specified through an input unit. The interference determining unitdetermines the presence or absence of interference between each of plurality of members and the object Abased on respective member existence areas of the plurality of members and the object existence area.

If a management server receives an invitation request, the management server acquires a requester's reference identification information corresponding to a requester's user identification information, a receiver's reference identification information corresponding to a receiver's user identification information, and an identification information, by referring to a user information table. The management server generates a record in which a status information is set to 'pending', and records the record in an invitation table. Assuming that the game to which a user A wants to invite another user B is a game b, the other user B who builds a friendship with the user A in a game c, the user A manages one terminal device, and the other user B manages another terminal device. In this case, the management server sends an invitation mail indicating that there is an invitation from the user A in the game b to the other terminal device.

Management server, controlling method thereof, non-transitory computer readable storage medium having stored thereon a computer program for a management server and terminal device

A management server is provided with an accepting unit for accepting identification information identifying an application, a specifying unit adapted for specifying a part or all of candidate users satisfying all of conditions out of one or more users with whom a request user's friendship is built in one or more utilized applications that the request user has utilized, a first condition in which the candidate user utilizes the application identified by the identification information, a second condition in which the request user's friendship with the candidate user has not been built in the identified application, a third condition in which a friend upper limit is not encountered, and a display controlling unit adapted for displaying the part or all of the candidate users specified by the specifying unit in the terminal device of the request user in order to select one or more users from the part or all of the candidate users.

An imaging lens includes, in order from an object side, a first lens with a positive refractive power having a biconvex shape; an aperture stop having a predetermined aperture diameter; a second lens with a positive refractive power having a concave surface on the object side, at least one of the object-side surface and an image-plane-side surface of the second lens being aspherical; and a third lens with a negative refractive power having a concave surface on the object side and an aspherical surface with an inflection point in an effective-diameter area on the image-plane side, whereby aberrations can be effectively corrected, the total length of the lens system can be reduced to reduce the overall size, in particular the thickness, and a shutter can be readily accommodated.

Imaging lens

A zoom lens includes a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a third lens unit having a positive refractive power. The first, second, and third lens units are arranged in that order from an object side to an image plane side of the zoom lens. The first lens unit includes a first lens having a negative refractive power, the second lens unit includes a second lens having a positive refractive power and a third lens having a negative refractive power, and the third lens unit includes a fourth lens having a positive refractive power. During zooming from a wide-angle end to a telephoto end, the first lens unit is fixed, and the second lens unit and the third lens unit are moved.

Zoom lens

An imaging lens includes, in sequence from the object side to the image plane side: a first lens with a convex object side surface and having a positive overall index of refraction; an aperture stop having a predetermined diameter; a second lens with a convex object side surface and having an overall positive index of refraction; and a third lens with a concave object side surface and an overall negative index of refraction. At least one surface of the first lens is formed as an aspherical surface. Both surfaces of the third lens are formed as aspherical surfaces, with the image side surface having an inflection point at which the curvature of the surface changes within the effective diameter range. The imaging lens provides superior optical characteristics and is compact and suited for use in mobile cameras installed in portable telephones, PDAs, and the like.

The present invention includes, from an object side to an image-plane side: an aperture stop with a predetermined diameter, a first lens with a positive refractive power having a convex surface on the object side, a second lens with a positive refractive power having a concave surface on the object side, and a third lens with a negative refractive power having a convex surface on the object side. The second and third lenses have aspherical surfaces on their object-side and image-plane-side surfaces. The third lens is formed with an inflection point where the curvature orientation changes within the effective diameter range of the aspherical surface on the image-plane side. An appropriate back focus is maintained while the total length of the lens system is reduced. A compact, thin, high-performance design is achieved, which effectively corrects various aberrations, especially astigmatism and distortion, and is suited for digital cameras using high-density solid-state imaging elements of one million pixels or more.

The present invention is directed to a reconfigurable toy which is capable of simulating a locomotive train in one position and through a timed release being reconfigured into a rocket plane configuration in a second position.

Rocket train toy assembly

A vehicle toy assembly is provided having the capability of being reconfigured through a time control action into a second configuration. During the transformation, projectiles can be fired and a miniaturized vehicle can be released and propelled from the toy assembly.
