Disclosed is a process for producing aragonite crystal form calcium carbonate with an acicular shape characterized by premixing aragonite crystal calcium carbonate and Ca(OH).sub.2 to prepare an aqueous slurry, adding a water-soluble phosphoric acid compound into the aqueous slurry, and introducing CO.sub.2 gas into the aqueous slurry to cause the carbonation reaction to take place. According to the present invention, aragonite crystal form calcium carbonate in an acicular shape with a large particle size is produced.

A map display apparatus includes a map data memory which stores map data necessary for plotting a map of a predetermined region; a map display which reads map data out of the map data memory and plots a bird's-eye view display by projecting the map data read out from the map data memory onto a projection plane which makes a projection angle with a plane of the map data read out from the map data memory, the projection angle being greater than 0° and less than 90°, the bird's-eye view display including identifying marks which identify items in the bird's-eye view display; and an identifying mark overlap preventer which prevents identifying marks from overlapping one another in the bird's-eye view display.

A warp-knitted fabric from which garments can be obtained without accompanying any sewing process. The fabric is constructed by first and second layers 10 and 12, which construct first and second sides, respectively of garments and which are basically separated from each other. The first and second layers are connected with each other along an outline 14 of the garment. At locations corresponding to sleeves of the garment, the fabric is integrated with indicator lines CL1, CL2 and CL3 for effecting a cutting of the garment at the sleeve portions. A wearer selects one of the indicator lines and uses the selected line as a guide for effecting a cutting at the sleeve portions so that a desired sleeve length which is best fitted to the wearer is obtained.

A map display apparatus for displaying perspective image of a map. The apparatus includes an image display device for displaying the perspective image of the map and a map data storage device for storing map data. Map drawing means is included for preparing map drawing data using the map data and for displaying a perspective image of the map on the display device on the basis of the drawing data. The map drawing means transforms coordinate data of a map into data suitable for display of the perspective image of the map. The data transformation is accomplished by perspectively projecting the coordinate data onto a predetermined projection plane with a view point at a desired position. The projection plane is determined on the basis of two predetermined points in the map data, such as the current position of a vehicle and the destination, so that drawing positions of the two points after the perspectively projecting operation are coincident with predetermined positions.

A paper cutter for achieving high speed cutting having a simplified structure since movement of a blade can be controlled by a linear motor. A low level of noise can also be realized since typical mechanical elements for transferring power are eliminated. The movable blade forms less than a fifty degree angle with respect to a blade edge of the stationary blade, in the direction of blade motion, so that locally concentrated wear it minimized. By using a rotary blade as a movable blade, paper can be cut in both directions by reciprocating the movable blade.

摘要:
In a navigation system using a bird's-eye view display mode, map data on a plan view map are subjected to a perspective projection conversion to obtain drawing data on a bird's-eye view map. An input of the position of a view point is accepted, and a projection plane for a bird's-eye view is determined so that the display positions of the two points which have been subjected to perspective-projection conversion are coincident with predetermined positions. Alternatively, an input of a scale is accepted, so that the display positions of the two points after the perspective projection conversion are coincident with predetermined positions and the drawing scale is coincident with the input scale. In a further alternative, an input of the projection angle is accepted, and the projection plane is determined on the basis of the projection angle and the position of the view point.
