Predetermined travel locuss are set in a three-dimensional virtual space. Menu panels displaying menu items are arranged along the travel locuss assuming a display position set as a local origin so that the normal to each LCD panel will face a virtual camera. The transparency of a menu panel is raised in accordance with its distance to the virtual camera. A scroll operation moves menu panels along the travel locuss connecting display positions P until a selected specific menu panel reaches the display position P. A display screen is drawn with the virtual camera and menu panels are three-dimensionally displayed in rolls. By sliding a stylus pen on the LCD panel, the menu screen displayed on the LCD panel scrolls at a velocity corresponding to the drag velocity. When the stylus pen is released from the LCD panel, an application program corresponding to the menu display entity (crosshatched) is activated.

The present invention provides a radar apparatus, which can diagnose failure at low cost with high accuracy, and a failure diagnosis method thereof. An antenna serves as both a transmit antenna and a receive antenna. A transmit and receive select switch switches the transmission and reception of the antenna. A control unit measures a power value based on an output signal of a receive wave received by the antennas, and judges that the transmit and receive select switch fails when this power value exceeds a threshold.

On a channel region enclosed by a pair of diffusion layersA,B, a first insulating layer, a charge accumulative layer, and a second insulating layerare stacked up in this order, and on the second insulating layer, two control gate layersA,B spaced across a gap Gare disposed in the middle of the channel width direction. The charge accumulative layerhas discrete charge traps, and, accordingly, movement of charge in the layer is limited. In the charge accumulative layer, the charges injected depend on the writing voltage applied in control gate layersA,B and can be localized beneath the control gate layersA,B through which a writing voltage is applied. The presence or absence of charges can be controlled in every charge accumulative region beneath the control gate layersA,B, so that multi-value storage in the memory cell can be realized.

In an FM-CW radar apparatus which determines the azimuth to a target by a phase monopulse technique, an abnormal value resulting from the presence of multiple targets is detected. Three receiving antennas are arranged at spacings of 5&#x3bb;/4 and 6&#x3bb;/4, respectively, and it is determined whether the difference between the azimuth obtained from the combination of the receiving antennas spaced 5&#x3bb;/4 apart and the azimuth obtained from the combination of the receiving antennas spaced 6&#x3bb;/4 apart is smaller than a predetermined value or not; when the condition has been satisfied n times in succession, it is determined that the detected value is normal. On the other hand, if the condition has not been satisfied n times in succession, or if the difference is not smaller than the predetermined value, it is determined that the detected value is an abnormal value resulting from the presence of multiple targets.

The determination unit determines type of the target on the basis of judgment result of the judgment unit.
