Title: Method for preparing free curved surface
Inventor: KIKUCHI ATSUSHI
IPC: G06T15/00
Filed: 1988-03-17
Abstract: PURPOSE:To prevent an influence from being given to a surrounding patch form by replacing the vector coefficient of a necessary auxiliary vector to be equal value for the patch of a vector function, which is spread in a frame space to form a free curved surface, obtaining a specified control side vector with using a prescribed expression and spreading again the patch. CONSTITUTION:When a patch S(U,V),C is spread again, auxiliary vectors C0X and C3X are obtained from nodal points P(0,0)AC and P(0,3)AC in the both edges of a shared border COMAC with an adjacent patch S(U,V)A, etc., toward the nodal point which is correspond to an adjacent patch S(U,V)D on a plane surface to include control side vectors (a0, b1) and (a3, b3) of the adjacent patch. The coefficients of component in a direction, which crosses an internal border COMac of these vectors C0X and C3X, are replaced with the mutually equal values and with using a trangential plane continuous expression, control side vectors C1 and C2, which expresse internal control points P(1,1)CA and P(1,2)CA of the patch S(U,V)C are obtained. Then, based on this result, when the patch is spread again, without giving the influence to the adjacent patch, the patch can be spread again.

Title: Optical beacon system
Inventor: KANDA SEIJI
IPC: H04B10/00
Filed: 1995-03-24
Abstract: PURPOSE: To surely recognize the position of a counterpart station without malfunction by driving a beacon transmitter and a beacon receiver alternately with a predetermined cycle and making switching repetition cycles different between an earth station and a space station. CONSTITUTION: While beacon transmitters 6-A, 6-B are turned ON to output transmission beacon lights, beacon transmission/reception timing-controlling parts 9-A, 9-B close shutters of beacon receivers 5-A, 5-B. When the transmitters 6-A, 6-B are turned OFF not to output transmission beacon outputs, the controlling parts 9-A, 9-B open the shutters of the beacon receivers 5-A, 5-B. The controlling parts 9-A, 9-B in an earth station A and a space station B repeatedly control in this manner with repetition cycles. Accordingly, malfunction owing to leaking transmission beacon lights is prevented. The repetition cycles for the controlling parts 9-A, 9-B to switch the transmission and receipt of beacon lights are made different, from one another, so that the beacon lights are surely transmitted/received.
