Abstract: A vehicular air-conditioning apparatus includes a photocatalytic module in which light is radiated on a photocatalytic filter to sterilize the photocatalytic filter. In particular, vehicular air-conditioning apparatus incudes: a duct to allow conditioned air to flow therethrough; the photocatalytic filter mounted in the duct and coated with a photocatalytic material to remove harmful substances in reaction to light energy; and a rotation unit rotatably mounted in the duct. In particular, the rotation unit is provided with a light source to radiate light toward the photocatalytic filter. When the rotation unit is rotated, a position of the light source is changed in a rotational direction of the rotation unit such that the light is radiated on the photocatalytic filter over an increased range. Thus, a filter sterilization effect is improved over the entire area of the photocatalytic filter with reduced number of light sources.

Abstract: Disclosed is a method for manufacturing lithium metal phosphate (LMP) having, as a precursor, crystalline iron phosphate salt having a (meta)strengite structure or metal-doped crystalline iron phosphate salt having a (meta)strengite structure, the method comprising the steps of: mixing a lithium raw material with crystalline iron phosphate salt in a slurry phase or a cake phase; and heat-treating the mixture. The method, by mixing a lithium (Li) raw material and a carbon (C) coating material with crystalline iron phosphate salt in a slurry phase or a cake phase, allows elements such as Li, Fe, P and C to be homogeneously mixed, and then, by having the elements dried simultaneously, enables manufacturing of high-quality LMP. Therefore, the present invention is not only capable of providing convenience during the manufacturing process for lithium metal phosphate, but also capable of providing a lithium secondary battery positive electrode active material having excellent battery characteristics.

Abstract: A facsimile/copy apparatus and method of operation are provided for transmitting a single page document to a plurality of different locations, for transmitting a plural page document to a single location and or for making photostatic copies. The apparatus includes a switch for selecting either a copy function or a facsimile function and memory to identify a number of readings to be performed with the selected function. Feed rollers feed each sheet into the apparatus, and a reversible transfer roller is provided to move the sheet in either of two opposed directions relative to a reader. Odd number readings are read when the sheet is moving in a first direction, while even number readings are obtained while the sheet is moving in an opposed direction. The number of readings that have been taken are compared to the number of required readings stored in the memory. After completion of the required number of readings, the sheet is ejected from the facsimile/copy apparatus.
