A navigation device for a motorcycle operable in a comfortable position during driving by solving a problem that it is hard to operate the navigation device during driving and easily mounted on a vehicle by solving the problem that it is hard to mount the navigation device on the vehicle. The navigation device includes a navigation display section for displaying navigation information such as a destination and the current vehicle position, a control unit for controlling the navigation display section, and an operating section for performing an input operation to the control unit. The operating section is separated from the navigation display section and the operating section is disposed on the side of a vehicle body.

Fundamental laser light having a wavelength of 1,064 nm, for example, is generated by a solid-state laser medium. The fundamental laser light is reflected by a flat mirror and amplified again passing through a Q-switch, a solid-state laser medium, a Q-switch, a Q-switch, a solid-state laser medium, and a Q-switch. The fundamental laser light furthermore reflects from a flat mirror, passes through a flat mirror for second-harmonic resonance, passes through a lens, then reflects from a flat mirror for laser light separation, and enters a nonlinear optical crystal for the third harmonic and a nonlinear optical crystal for the second harmonic. A solid-state laser generator can thereby be obtained in which second-harmonic laser light obtained in an intermediate stage can be used with good efficiency and be converted, for example, to third-harmonic laser light and higher-harmonic laser light with higher efficiency and higher output.

A vehicle navigation system that uses a portable information terminal. The navigation system displays route guidance information by receiving GPS satellite radio waves, and includes a navigation unit that generates route guidance information, a meter panel of a meter unit, which displays only part of the route guidance information, and a display panel of the navigation unit, which displays every selected item of the route guidance information. The meter panel of the meter unit is disposed within the visual field of the driver when in driving the vehicle. On the other hand, the display panel of the navigation unit is disposed outside of the visual field of the driver when driving the vehicle. The resulting configuration provides a vehicle navigation system that provides the driver with the minimum necessary information when driving, and provides additional detailed information when needed, combined in a system that affords excellent operability.

High load screwing work, calking work, or press-fitting work ancillary to assembly work can be performed by a low rigidity robot such as a tabletop robot by, in the screwing work, returning the torque applied to one of the bolt and nut from a rotation drive unit such as a motor and reduction gear to the casing part of the rotation drive unit through a relative rotation inhibiting mechanism supporting the other and, in the calking work or press-fitting work, returning the action force applied from a driving means such as an air cylinder to the calking punch etc. to the casing part of the driving means through the workpiece and grip parts. Therefore, the path of transmission of the torque or action force is kept inside the robot hand and does not leak to the outside.

The present invention relates a GPS receiving apparatus having improved measurement precision as the result of selectively fetching only some of the signals transmitted by a number of satellites. The GPS receiving apparatus includes an antenna for receiving the electric waves from the satellites, an elevation-angle-computing unit for finding an elevation angle of each satellite on the basis of the electric wave received from the satellite, and a comparison unit for comparing the elevation angle with a predetermined reference elevation angle. Only electric waves transmitted by those satellites having an elevation angle greater than a predetermined reference elevation angle are selectively used for computing a position.

To provide a map information display system for a moving body that can extract and display map information as required without updating set way points or routes. A limited region map information generating device for extracting map information for only a limited region based on a route being traveled and on a scheduled route, and for generating limited region map information includes a route generating device for generating a moving body route based on the route point coordinate information and road information, an extracting device for setting map information of a strip-shaped region extending along the moving body route as the limited region map information, and a strip-shaped region adjusting device for adjusting a size of the strip-shaped region so as to include the moving body route when it is determined that the information amount of the limited region map information is larger than a specified storage capacity but less than a storage capacity of the storage device.
