The invention provides a display control apparatus and a display control method wherein, where digital gradation display is performed, occurrences of a moving picture pseudo contour can be reduced simply. A signal production circuit produces a signal for driving a display section so that light of divisional light amounts obtained by dividing light amounts corresponding to bits which compose digital values which are pixel values may be emitted in a such manner as to be distributed within a time corresponding to one screen. In this instance, where both of a first light amount corresponding to a predetermined bit and a second light amount corresponding to a bit in a lower order by one bit to the bit are divided, the first and second light amounts are divided so that the division number of the first light amount may be smaller than twice the division number of the second light amount.

A linear motion guide unit is disclosed in which a slider moves relatively of and along a track rail by virtue of rolling elements of balls or rollers. The rolling elements are allowed to recirculate from a load raceway formed between the track rail and the slider to a non-loaded area composed of a turnaround formed in the slider to communicate with the load raceway, and a return passage formed in the slider to communicate with the turnaround. The return passage is encircled with a sintered resinous member of porous texture. Lubricant absorbed and held in voids in the sintered resinous member can be supplied over a prolonged period to the rolling elements, thereby lubricating the rolling elements to make the frictional resistance less, which might be encountered when the slider moves on the track rail, and ultimately helping ensure the improvement in durability.

A scanning device periodically changes the direction of the transmission of an electromagnetic wave from an electromagnetic wave generating device. A first driving device operates for repetitively driving the electromagnetic wave generating device a plurality of times per one period of the change of the direction by the scanning device, and thereby for repetitively transmitting a distance measurement electromagnetic wave. A second driving device operates for, before the first driving device drives the electromagnetic wave generating device, driving the electromagnetic wave generating device and thereby transmitting a judgment electromagnetic wave having an energy smaller than that of the distance measurement electromagnetic wave. An obstacle judging device permits the first driving device to drive the electromagnetic wave generating device next in cases where a detected obstacle is absent, and inhibits the first driving device from driving the electromagnetic wave generating device next in cases where a detected obstacle is present.

An optical scanner and a two-dimensional scanning device using the same are provided. The optical scanner includes a scanning mechanism and a swing support. The swing support is designed to support the scanning mechanism on a housing so as to allow the scanning mechanism to swing and made up of a plurality of springs. The springs are so constructed so as resist unwanted vibrations acting on the optical scanner in directions different from a scan direction, thereby ensuring a stable scan of a light beam at all the time.

A picture display method and apparatus in which a light source is lengthened in service life and optimum color reproduction is realized, while the light utilization efficiency is improved to reduce the power consumption and the size of the apparatus. The red, green and blue illuminating light beams radiated from the light-emitting diodes 12R, 12G and 12R, are illuminated via relay lenses and field lenses on picture display light valves 11R, 11G and 11B and spatially modulated in intensity so as to be synthesized by a synthesis prism 10 and so as to be projected to an enlarged scale on a screen 17. The profile of the light radiating portions of the light-emitting diodes 12R, 12G and 12B are set so as to be the same or similar to the profile of a picture display area of each of the picture display light valves 11R, 11G and 11B in order that the profile of the light beam illuminated on the picture display area will be in keeping with the profile of the picture display area.

A semi-spherical system holding mechanism 8 such as to cover the head portion of the user is provided in the upper portion of a user holding mechanisms 9 such as chair, sofa, or the like. A display apparatus 7 is fixed in the system holding mechanism 8. In the display apparatus 7, a video image displayed on a display panel 14 is enlarged by a lens 13, so that a virtual image is formed. The virtual images which are observed by the right and left eyes of the user are arranged at the same position in a space.

A plurality of dispersive air pipes for combustion (11) containing a plurality of dispersive air holes and projecting in a cantilever fashion from the side walls (1b, 1c) in an oblique downward direction are provided in the lower portion of a combustion zone (2b) of a furnace main unit (1) which includes an ash discharge outlet (6) formed in the base portion of the furnace main unit, and an incombustible material discharge space (12) is formed between the ends of the dispersive air pipes for combustion (11). As a result, incombustible material accumulating on the dispersive air pipes for combustion (11) is guided to the incombustible material discharge space (12) and then discharged.

An aperture antenna suitable for a radar system of an automotive vehicle is provided which includes three or more primary radiators and a feeding circuit. The feeding circuit is designed to supply electromagnetic signals to adjacent two of the primary radiators through discrete feeders to radiate in phase electromagnetic waves and to extract signals received by the two of the primary radiators separately. This enables the radiation of radar waves over a wider area without increasing the radiation power.
