摘要:
An apparatus for generating an image includes a vehicle moving at a predetermined direction; and a plurality of cameras arranged on the vehicle along a linear line parallel to the predetermined direction and at different angles from each other with respect to the predetermined direction so as to include all areas of images to be acquired. The apparatus forms one image by integrating images at the same point acquired by the cameras, respectively without being synchronized the cameras with each other and using any external sensor.

摘要:
An output voltage of a switching power supply is regulated to a target value. When the target value of the output voltage is altered, the reference value is changed monotonously and linearly a plurality of times at a plurality of gradients to the altered target value. An input voltage of the power supply is switched in response to a switching pulse with the duty ratio calculated according to a difference between the reference value and the output voltage.

The navigation apparatus includes a unit for displaying a real image on a display screen on the basis of real image data, and a unit for displaying additional information such as a primary place name or a primary building name in a position where the additional information should be displayed on the real image, on the basis of additional information data corresponding to the additional information and position data showing the position where the additional information should be displayed. Further, the navigation apparatus has a function of limiting the display area of the additional information so as to prevent the additional information from being displayed in an area having a relatively high level of importance. Thus, the real image is prevented from being difficult to see in the area having a high level of importance.

摘要:
The present invention provides an image display device in which it is possible to obtain an image display of high brightness and high contrast by preventing the halation which may be generated in a peripheral portion of a display image. By providing a carbon film which attenuates the reentry of secondary electrons, which are generated when electron beams impinge on an anode, to a back surface of the anode, even when primary electrons impinge on the anode, the secondary electrons are hardly emitted from the anode. At the same time, a trace amount of emitted secondary electrons are mainly formed of electrons having a small energy. Hence, these emitted secondary electrons are scattered and hardly reenter the anode.

Provided is a herbicide composition which comprises a combination in a specific proportion of 2-[(4,6-dimethoxypyrimidin-2-yl)hydroxymethyl]-6-methoxymethyl-N-difluoromethanesulfonylanilide as the component (A) and either one of fifteen kinds of compounds including 4-(2-chlorophenyl)-N-cyclohexyl-N-ethyl-4,5-dihydro-5-oxo-1H-tetrazole-1-carboxamide as the component (B), none of which has been used in combination with the compound as the component (A). By an application of the herbicide composition to a paddy field in a specific dose, an excellent herbicidal effect is obtained against various kinds of weeds growing in paddy fields and the chemical damages thereof to paddy rice is extremely low.

In a switch, a pad bottom is provided on a rubber switch. The pad bottom has a first opening and a second opening. A pad top is operable to move the pad bottom so as to depress the rubber switch. The pad top includes a first leg portion which has a hook and a second leg portion which has a screw hole. The hook is engaged with the pad bottom through the first opening. A screw threads in the screw hole through the second opening to fix the pad bottom to the pad top.

The present invention provides a display device which can maintain a gap between a front surface panel 1 and a back surface panel 2 at a given value and maintain the air-tightness of a sealed space defined between the front surface panel 1 and the back surface panel 2 even when the gap is relatively large. To achieve such an object, the display device includes the back surface panel 1, the front surface panel 2 and the outer frame 3, the outer frame 3 is constituted of a plurality of divided wall members 3X1, 3X2, 3Y1, 3Y2 and 3C1 to 3C4. Further, at least at some portions where neighboring wall members are engaged with each other, oblique surfaces 3P are formed and a crossing angle which is made by a normal line of the oblique surfaces 3P and a normal line of the back surface panel 1 or the front surface panel 2 is set to an acute angle.
