Light emission data is supplied to an RDATA latch 13R, a GDATA latch 13G, and a BDATA latch 13B and latched as R, G, and B data for every pixel. In an arithmetic operation processing unit 14, an arithmetic operation is performed using the latched R, G, and B data and a chromaticity correction coefficient Cij written in a chromaticity correction coefficient register 16. An arithmetic operation result of the arithmetic operation processing unit 14 is supplied as correction light emission data into a data memory 15 and stored. In a luminance correction data memory 20, luminance correction data is supplied to a constant current driver 18 in accordance with a supplied control signal. The constant current driver 18 drives an LED display 19 in accordance with the correction light emission data and the luminance correction data.

The present disclosure describes systems and methods for enhancing the brightness characteristics of a three-dimensional (3-D) image viewing apparatus. According to embodiments of the present disclosure, a 3-D image viewing apparatus may comprise a frame, a first lens disposed within the frame and a second lens disposed within the frame. The first lens may transmit light within a blue spectrum, a green spectrum, and a red spectrum at a first pre-determined intensity. The second lens may transmit light within an amber spectrum and an offset spectrum at a second pre-determined intensity. In certain embodiments, the offset spectrum may comprise a violet spectrum. Additionally, in certain embodiments, at least one of the first and second lenses may comprise a protective, anti-reflective lens

In an electric two-wheeled motor vehicle including: an electric motor for generating power to drive a rear wheel; a battery for supplying electric power to the electric motor; a rider seat on which a rider seats; a housing box disposed below the rider seat; and a side cover covering the housing box below the rider seat, the electric two-wheeled motor vehicle configured to allow charging of the battery, an opening (118) covered with an openable and closeable lid member (120) is provided in the side cover (48), and a power-receiving-side connector (67) to which a power-supplying-side connector leading to an external power source can be inserted and connected is fixed and disposed between an outer surface of the side cover (48) and the housing box to face the opening (118). Accordingly, it is possible to eliminate the requirement for a rider seat to be opened in charging of a battery and thereby facilitate the charging work.

A display tube assembly is provided, in which plug pins are mounted on a printed circuit board, this printed circuit board having the plug pins soldered thereto is attached to a display tube and the display tube is accommodated in a case thereby being made watertight. According to this arrangement, the plug pins, the printed circuit board and the display tube are coupled together in the outside of the case so that a working property in the assembly process can be improved considerably. Further, since a window portion is not provided at the rear surface of the case, the reliability in the watertight process in the display tube can be improved considerably.
摘要:
In a motorcar space heating system of the type having a heat pipe comprising a heat absorbing element for receiving heat from the exhaust gas of the motorcar engine and a heat discharging element for heating air flowing into a car interior space to be heated, the heat pipe is separated, at an intermediate heat exchanger installed in a working fluid passage connecting the heat absorbing and discharging elements, into a heat absorbing section and a heat discharging section. The working fluids within these two sections are therefore not intermingled with each other. A pipe extends from the intermediate heat exchanger so as to be communicative at one end thereof with the heat absorbing section. The other end of the pipe extends into a working fluid reservoir tank. When the pressure within the heat absorbing section rises as a result of increase of the quantity of heat absorbed at the heat absorbing element, the working fluid is allowed to flow through the pipe into the reservoir tank and is stored therein in liquid form. When the pressure within the heat absorbing section is reduced, the liquid working fluid in the reservoir tank flows back into the heat pipe.

A flat thermionic cathode is provided with a substrate having at least one main heating element thereon to produce at least one substantially localized area of heat and a sub-heating element to substantially define a heating area, the localized area being produced within the heating area. A cathode element including electron emissive material is disposed at the localized area. While the localized area tends to produce a temperature gradient directed from the localized area toward the perimeter of the substrate so as to create thermal stress in the substrate along the perimeter thereof, the sub-heating element reduces this temperature gradient and, consequently, the thermal stress.

Provided are a webbing-threading member and a seatbelt device that can prevent deviation of webbing (a so-called jamming phenomenon) by preventing rotation of the webbing-threading member. A webbing-threading member 1 of the present invention includes a body 2 rotatably mounted on the side of a vehicle, a threading hole 3 formed in the body 2 for guiding the webbing W, and a guide piece 4 placed on a surface of the threading hole 3 and forming a sliding surface 41 over which the webbing W slides. The guide piece 4 has, on the sliding surface 41, engaging grooves 42 that cause a pressing force to act in such a direction as to rotate the body 2 toward a vehicle front side at the time of withdrawing the webbing W, and that cause a pressing force to act in such a direction as to rotate the body 2 toward a vehicle rear side at the time of retracting the webbing W.
