    Abstract: A backlight provides uniform emanating light for a liquid crystal display. In the backlight, light emitted from a light source is incident on a receiving end surface of a light guide plate and emanates through a top surface toward a liquid crystal panel. A bottom surface includes a reflecting hollow wedge extending along the receiving end surface and varying in depth, as measured from the bottom surface, in correspondence with distance from the end surface. A dividing flat portion orthogonal to the reflecting hollow wedge divides the reflecting hollowed portion, and an output surface includes a prism having parallel ridges extending in a direction orthogonal to the receiving end surface.

    Abstract: An improved attitude control system for tunnel boring machine shields is provided. A laser beam transmitter is installed in an already bored tunnel behind the machine shield for transmitting a laser beam in parallel to a predetermined tunneling direction and a device for receiving the beam is installed in the shield for detecting any deviation of the shield from the beam so that, when the deviation is detected during tunneling work performed by rotating a foreward end cutter head of the shield and propelling the shield toward tunnel face ground with a plurality of jacks installed at rearward end of the shield, the jacks are selectively driven in response to resultant deviational direction and amount of the detection so as to remove the deviation.

    Abstract: A brake-controllable brushless motor has a rotor and a stator having polyphase coils; a polar position detector whereby electric power is supplied to the coil selected by its phase in response to the polar positions of the rotor detected by the polar position detector; a driver division for controlling the electric supply to the coils; a motor pulse identifier for recognizing motor pulse signals fed from the polar position detector; and a delayed pulse generator for producing phase-delayed pulse signals in response to the pulse signals fed from the motor pulse identifier, thereby ensuring that when the brushless motor is braked, the phase delay of the delayed pulse signals is progressively and continuously enlarged, and that the coils receive a controlled electric supply from the driver division in response to the delayed pulse signals.

    Abstract: A method for manufacturing a thin-film semiconductor includes polycrystallization to focus visible light pulse laser into a line shape on a surface of an object to be irradiated, and repeat irradiation with displacing the visible light pulse laser such that a line-shaped irradiated region is overlapped with a region irradiated at a next timing in a width direction of the line-shaped irradiated region, to form a polycrystalline silicon film on the surface of the object. The step of polycrystallization applies ultraviolet light pulse laser onto a second irradiated region partially overlapping the first irradiated region while or before the visible light pulse laser is applied to the first irradiated region.
