A drawing parameter setting method capable of setting drawing parameters for an XY plotter.When two vertexes (P1, P2) of a drawing subject region including a figure (F1'), for which a figure conversion process including figure movement, enlargement and reduction has been performed on a CRT screen (5a), are specified, a processor calculates the amount of movement of the figure before and after the conversion and a figure conversion scale, and also calculates coordinate positions ((LDX, LDY), (RUX, RUY), (MX, MY) of the two vertexes and a center (P3) of the drawing subject region. When it is determined that the drawing subject region and plotter paper (100) are similar in shape, based on the calculated ratio between longitudinal and lateral lengths of the drawing subject region and the calculated ratio between those of the plotter paper, the processor calculates the maximum plotting scale by dividing the product of the conversion scale and the longitudinal or lateral length of the plotter paper by the longitudinal or lateral distance between the two vertexes, and automatically determines the coordinate position (OX, OY) of the lower left vertex (P4) of a similar rectangle containing the drawing subject region such that the lower left vertex of the similar rectangle is correlated with the origin (PPO) of a plotter coordinate system. The figure is plotted at a suitable place on the maximum scale in accordance with the amount of movement of the figure origin and the coordinate position of the vertex of the similar rectangle.

The original planar shape or developed shape of a product to be manufactured by bending is determined using a computer-aided design system. An operator operates a tablet unit to prepare, first and second projection drawings of, e.g., an L-shaped product, projected onto two planes parallel to the outside of first and second sides of the product, with a bending line in common. The computer-aided design system displays the first and second projection drawings on a display screen in accordance with shape data which defines the two projection drawings (S1). In response to the operator picking two vertices of each projection drawing on the side of the bending line using the tablet unit (S2, S3), the processor calculates distances of movement in the X- and Y-axis directions and the rotational angle of the second projection drawing required for the alignment of the two sets of vertices (S5). Based on these calculated values and the amount of expansion or contraction of the product material accompanying the bending work, calculated in accordance with input data indicative of the thickness, bending angle, and bending direction, the processor prepares shape data indicative of the product shape prior to bending and causes the developed product shape to be displayed on the display screen (7).

A radar system includes an arithmetic processing unit, which calculates the second derivative of the intensity of a reflected wave and determines whether a target is an upper structure or a vehicle, based on the second derivative. Alternatively, the arithmetic processing unit decomposes the waveform of the intensity of the reflected wave into frequency components and determines whether the target is an upper structure or a vehicle, based on the intensity of a predetermined frequency component.

To enable a regenerated sound in the high-note range to sufficiently reach an ear of an operator (rider) during travel. A meter display unit is provided for displaying drive information such as a vehicle speed or a travel distance. Left and right speakers are disposed on both sides of the meter display unit for generating regenerated sounds such as English conversation and music. The left speaker includes a left midrange/woofer unit disposed on the left side of the meter display unit for regenerating midrange/low-note sound and a left tweeter unit disposed between the meter display unit and the left midrange/woofer unit for regenerating high-note sounds. The right speaker includes a right midrange/woofer unit disposed on the right side of the meter display unit for regenerating midrange/low-note sound and a right tweeter unit disposed between the meter display unit and the right midrange/woofer unit for regenerating high-note sounds.

Various targets are detected in a more accurate manner. Provision is made for a receiving antenna part that has a plurality of receiving antennas arranged in a horizontal direction with a part thereof being shifted in a vertical direction from the others, and has a plurality of combinations of the receiving antennas, of which each combination detects an azimuth in the horizontal direction and an azimuth in the vertical direction of a target; and detection means that detects the target a plurality of times while changing the combination of the receiving antennas. The detection accuracy of the target can be enhanced by making a comparison between at least two detection results obtained by the detection means.

An object detecting device and an object detecting method capable of performing appropriate object detection that distinguishes an approaching moving object from a stationary object accurately. The relative velocity of an object, which exists in the lateral direction of a vehicle, with respect to the vehicle is detected, the absolute velocity of the object in the horizontal direction of the vehicle is calculated on the basis of the detection signal, and it is determined whether or not the object is an approaching moving object on the basis of the absolute velocity of the object in the horizontal direction of the vehicle. Accordingly, since it is possible to accurately distinguish whether an object existing in the lateral or oblique direction of the vehicle is an approaching moving object or a stationary object, it is possible to appropriately determine whether or not the object is an approaching moving object.
