A moving device for moving on a wall surface that includes at least two or more vehicles each having a body, two main wheels each disposed on the body and rotatable around a shaft for moving on a wall surface, two rotation drivers which rotate each of the two main wheels respectively, and an adhesion mechanism disposed on the body to adhere onto the wall surface; and a coupler that connects vehicles located adjacent to each other among the at least two or more vehicles in the traveling direction of each of the vehicles.

Moving device

An adhesion devicethat defines a decompression space D to be decompressed between a wall surface W and the adhesion device, and adheres to the wall surface W, comprises: a basedisposed facing a wall surface W at a distance from the wall surface W and connected to a decompression devicethat depressurizes the decompression space D created between the baseand the wall surface W; a first partitiondisposed on a fringe of the base, wherein the first partitionforms the baseside portion of the peripheral wall of the decompression space D with an elastic member; a second partitiondisposed closer to the wall surface W side than the first partition, wherein the wall surface W side portion of the peripheral wall of the decompression space D is formed by an elastic member so that the wall surface W side end of the second partitioncontacts the wall surface W; and a first restricting memberformed in a frame shape corresponding to that of the second partitionby a member having a higher rigidity than that of the second partition, wherein the first restricting memberis disposed on the second partitionso as to restrict the deformation of the baseside end of the second partitionfrom being pulled into the decompression space D as the decompression space D becomes negatively pressured.

The acceleration-detecting type gyro apparatus includes: a gyro case; a gyro rotor which is supported within the gyro case by electrostatic supporting forces such that the gyro rotor is not in contact with the gyro case; electrostatic supporting electrodes for generating the electrostatic supporting forces; a rotor drive system for rotating the gyro rotor around the spin axis at high speed; a displacement-detection system for detecting displacements of the gyro rotor; and a restraining system having a feedback loop for correcting control voltages applied to the electrostatic supporting electrodes so that displacements of the gyro rotor become zero, the gyro rotor is annular-shaped, and the electrostatic supporting electrodes are disposed in a manner of surrounding the gyro rotor.

Acceleration detection type gyro device

An electrostatic supporting type acceleration detecting gyro apparatus is formed as an active type so as to be able to positively cancel a displacement of a gyro rotor. Control DC voltages for generating electrostatic supporting forces and displacement detection AC voltages for detecting a displacement of gyro rotor are applied to electrostatic supporting electrodes, and mechanism control circuits detect displacement indicating voltage signals (P.sub.1A) through (P.sub.4B). A displacement of the gyro rotor and the control DC voltages applied to the electrostatic supporting electrodes are computed based on the displacement detection voltages (P.sub.1A) through (P.sub.4B) outputted from the mechanism control circuits.

An acceleration detection gyro apparatus is of the electrostatic supporting type. This gyro apparatus call be made inexpensive, long in life, excellent in durability and can be applied to a wide variety of fields. A gyro rotor (20) is supported relative to a gyro case (21) by an electrostatic supporting force in a non-contact fashion and rotated about the spin axis along the Z axis by a rotor driving system. The gyro rotor (20) is disk-shaped and constructed by forming metal thin film electrodes on both surfaces of a plate member made of preferably an insulating material. The gyro apparatus includes a slave control system for slaving a displacement of the gyro rotor (20) relative to the gyro case (21) in the Z-axis direction (spin axis direction) and a central position control system for slaving a displacement of the gyro rotor (20) in the X-axis and Y-axon directions.

Acceleration-detection type gyro

An antenna having a central axis is supported on a supporting member which in turn is supported on an azimuth gimbal. The antenna and the supporting member are rotatable around an elevation axis perpendicular to the central axis gimbal is supported on a base and is rotatable around an azimuth axis perpendicular to the elevation axis. A first gyro having an input axis parallel to the elevation axis is secured to the supporting member, and a second gyro having an input axis perpendicular to both the central axis and the elevation angle axis is secured to the supporting member. An accelerometer is provided for outputting a signal representative of an inclination angle of the central axis relative to a horizontal plane. An azimuth transmitter is provided for outputting a signal representative of a rotation angle of the azimuth gimbal around the azimuth axis. The difference between a signal corresponding to the altitude angle of the satellite and the signal of the accelerometer is fed to the torquer of the first gyro, while the output signal of the azimuth transmitter and the signals corresponding to the ship's heading azimuth and a satellite azimuth angle are fed to a torquer of the second gyro to thereby direct the central axis of the antenna to the satellite.
