A navigation system constructed from a portable terminal device having a route search server provided with route search means for searching for a guidance route from a start point up to a destination; GPS receiving means for positioning a current position; imaging means; and display means for displaying, along with a peripheral image captured by the imaging means, a guidance route, a guidance image in the direction of advance, or an image representing a place of interest. The portable terminal device further has display control means for controlling display of the peripheral image displayed on the display means. The display control means controls the position of display of the peripheral image, captured by the imaging means, so that the center of optical axis of the imaging means is below the center of the display screen. Even if the direction of the optical axis of the imaging means is directed downward from a horizontal line, the horizontal direction of the peripheral image is displayed on the display screen.

A first sensor detects a rotational position of a first shaft in a noncontact fashion and generates a first output signal by phase-shifting a reference A.C. signal in accordance with the detected rotational position of the first shaft. A second sensor detects a rotational position of a second shaft in a noncontact fashion and generates a second output signal by phase-shifting the reference A.C. signal in accordance with the detected rotational position of the second shaft. First and second timing signals corresponding to phase shift amounts of the first and second output signals are output via respective output lines. Relative rotational position detection data, representing a rotational difference or amount of torsion between the two shafts, appears in a time difference between the first and second timing signals. A PWM signal, having a pulse width corresponding to a time difference between the first and second timing signals, may be output.

A map display device and a map display method, in which a building in a map is formed as a pseudo three-dimensional figure and arithmetic processing to display the figure as a bird's-eye view is simplified. The map display device 20 for displaying map data, formed from vector data, on a display means has a plane figure-for-bird's-eye-view creation means 218, a shift amount storage means 219, a building position determination means 220, and a figure data copying means 221. The plane-figure-for-bird's-eye-view creation means 218 creates, from the map data formed from vector data, a plane figure for creating a bird's-eye view. The figure data copying means 221 copies and draws the plane figure to display a bird's-eye view. This is performed based on the positions of buildings determined by the building determination means 220 and on the shift amounts stored in the shift amount storage means 219, and in this process, the plane figures are shifted upward on a display screen according to the shift amounts, and the copying and drawing are made one by one from a building positioned on the far side in the bird's-eye view.

An information terminal device having a drawing printing function to print a drawing such as a map or a route map is enabled to print the drawing without any reduction on rolled printing paper having a limited width. The information terminal device 30 includes printing data making means 37 for making the printing data, and angle calculating means 36. On the basis of the drawing data having the data of a drawing containing a bent point and the data of the angle of bend at that bent point, the angle calculating means 36 calculates the angle index, at which the rolled paper is folded to correspond to the bent point, and calculates the printing data, which divides the drawing at each bent point and which is taken in the longitudinal direction of the rolled paper, that is, the blank length which discontinues the drawing at the folded portion determined by the angle index. On the basis of the angle index and the blank length, the printing data making means 37 divides the drawing at each bent point and makes the printing data taken in the longitudinal direction of the rolled paper.

The first and second magnetic body sections form at least two ring-shaped variable magnetic coupling sections opposed to each other via a gap, magnetic coupling in each of the boundary sections varies in response to variation of a relative rotational position between the first and second shafts, and variation of the magnetic coupling differs in phase between the boundary sections. Coil section (30) includes magnetic-coupling detecting coils (L1-L4) provided in corresponding relation to the boundary sections. Each of the first and second magnetic body sections is of a cylindrical shape and has a plurality of magnetic teeth formed at unequal pitches along the circumferential direction thereof, and the magnetic teeth differ in axial length among tooth groups corresponding to the boundary sections.

A noncontact coupler comprising a pair of magnetic cores 1, 1 each having a U-shaped open magnetic path, a primary coil L1 and secondary coil L2 being wound around said cores 1, 1 separately respectively, said coupler transmitting AC electric power between said primary and secondary coils L1, L2 by means of an annular closed magnetic path B formed by opposing in proximity both open magnetic face sides of said cores, wherein said primary and secondary magnetic cores 1, 1 are respectively split at least at their sides facing to each other, and a gap forming a spatial magnetic path is interposed between said split pieces. A diameter a of a medium leg 51 positioned inside an annular groove 52 around in which the coils L1, L2 are wound (housed) is set almost equal to a width b of the annular groove 52. These provide effects of lightening a noncontact coupler while securing its performance and improving handleability with enhancing tolerance for positioning of the primary and secondary cores.
