摘要:
A lighting unit and a liquid crystal display device which can improve the efficiency of usable light. The lighting unit includes a light source, a light guide plate, and a truncated pyramid located between the light guide plate and the light source. The truncated pyramid has a base, a top smaller than the base, and a slope linking the base and the top. The light source is placed in close contact with the top of the truncated pyramid, and the light guide plate is placed in close contact with the base of the truncated pyramid. Light is propagated from a light emitting part of the light source to the light guide plate without passing through any air layer. Also, an unnecessary light removing structure is provided in the light guide plate near the incidence surface thereof.

There is provided wheel speed detection means for detecting a wheel speed V based on a pulse signal corresponding to a rotational speed of a wheel, driving torque integration means calculates an integral value TINdt of driving torque TIN generated by the engine, and running situation determination means determines a vehicle running situation based on an actual wheel speed V and the integral value TINdt of the driving torque TIN. That is, the running situation determination means appropriately determines the vehicle running situation by comparing the actual wheel speed V which varies according to the vehicle running situation, and the function f (TINdt) even when the actual wheel speed is in the extremely low speed region. The function f (TINdt) is the function of the integral value TINdt of the driving torque TIN, and is also the function of the estimated wheel speed VP that is estimated based on the integral value TINdt of the driving torque TIN.

A routing method in an ad hoc network formed by a plurality of mobile terminals includes receiving, at a mobile terminal forming part of the ad hoc network, a packet generated by an adjacent terminal, and determining, at the mobile terminal, whether to relay the received packet or not, based on presence or absence of a record of packet relaying by the adjacent terminal.

In each node of an optical transmission system: an optical preamplifier has an ALC function for maintaining an optical output level constant and an AGC function for maintaining the gain constant; the operational mode of the optical preamplifier is changed from an ALC mode to an AGC mode after the gain is set in the ALC mode; an optical postamplifier has an AGC function; an optical switch unit performs an optical crossconnect operation; and a thru-light-shutoff control unit makes a switch setting so as to shut off pass-through light in the optical switch unit and stop transmission of an optical signal having an unstable level to a next stage when the optical preamplifier operates in the ALC mode, and clears the switch setting when the operational mode of the optical preamplifier is changed to the AGC mode.

An optical scanning apparatus includes M number of light sources that includes M number of semiconductor lasers and M number of coupling lenses, where M is a positive integer, a deflecting scanning unit that deflects laser beams from the light sources to a surface to be scanned, and a transmission-type prism that deflects optical path of the laser beam from at least one of the light sources by an infinitesimal amount of angle. The prism is disposed between the light sources and the deflecting scanning unit, has an incident surface and an output surface nonparallel to each other, and can rotate around an axis of rotation substantially parallel to the optical path of the laser beam.

The invention relates to a backlight unit for liquid crystal displays, etc.; and its object is to provide a backlight unit not involving the problem that the emitted light leaks out of the optical waveguide, even when the space around the cold-cathode tubes in the light source unit for it is filled with a liquid of which the refractive index is nearly the same as that of the glass material that forms the outer wall of the cold-cathode tubes. The backlight unit comprises a housing 6 which houses cold-cathode tubes 2, 4 therein and of which the inner surface is coated with a light reflector 10; a transparent liquid filled in the housing 6; and an optical waveguide 1 made of a transparent substance and having a light-emitting surface S. The reflective surface of the light reflector 10 has a cross-section profile of X-T-U-V-W-Y, on which the light emitted by the cold-cathode tubes 2, 4 is reflected, and the thus-reflected light is led to the light-emitting surface S of the optical waveguide 1 at an incident angle not smaller than the critical angle to the surface S.
