Abstract: In order to control an attitude of a movable object having a flexible member (50) through an attitude maneuver, first, based on vibration of the flexible member at the time of the attitude maneuver, for example, a sampling function including no frequency components equal to or higher than a particular frequency is obtained. With the use of the sampling function, a control target value is created as a previously-frequency-shaping-type feedforward control law. Based on the control target value, attitude control data is created. The attitude control data can be used for the attitude maneuver with respect to the movable object.

Abstract: A connector includes a plurality of contacts. The connector includes an insulator having a plurality of through-holes for receiving the contacts. A pair of contacts are disposed in each of the through-holes. Since two contacts are disposed in the through-hole in the insulator, even if a fault occurs in one of the contacts, signal transmission in the same line can continuously be used. Moreover, since large areas of contact portions of the contacts are secured even in normal use, the capacity of electric current is increased.

Abstract: Disclosed is a topographic measurement system wherein at least one satellite is used to scan the earth surface and send picture frames of a target area captured at different positions to an earth station. The picture frames are combined to produce a number of pairs of frames which constitute a stereoscopic image of the target area. Each frame pair is analyzed according to a number of visual characteristics and evaluated with a set of fitness values representative of the degrees of fitness of the frame pair to topographic measurement of the target area. A total of the fitness values is obtained from each frame pair and compared with the total values of other frame pairs. A frame pair having the highest total value is selected as a best pair. A parallax between the best pair frames is determined to produce first and second sets of line-of-sight vectors for conversion to topographic data.

Abstract: Broadcast signal c is transmitted from a broadcast transmitter 5 to an artificial satellite 1 for predetermined signal conversion therein, whereby broadcast signals a1 to an are transmitted to the entire area of Japan. On-earth stations 6-1 to 6-n are installed for weather forecast data. These on-earth stations receive the broadcast signals a1 to an, respectively, transmitted from the artificial satellite 1, and transmit receiving state data b1 to bn, respectively, based on receiving level data to the artificial satellite 1. The receiving state signals are changed with variations of their radio wave attenuation according to whether it is cloudy, the cloud density, whether it rains or snows, etc. The receiving state data are collectively sent back to a weather forecast center 9. Weather forecast data e obtained by analysis in the weather forecast center 9 is transmitted to the artificial satellite 1, which in turn sends weather forecast data f back to the full area in Japan.
