Abstract: An image reading apparatus accurately determines the positions of image forming mirrors formed with an off-axis reflecting surface, while enabling any thermal expansion caused by a rise in temperature due to a rise in the surrounding temperature to be absorbed. Each image forming mirror formed with an off-axis reflecting surface comprises respective and independent units for determining the positions in the longitudinal direction, in the lateral position, and in the direction orthogonal to the reflecting surface. Holes with which the longitudinal position determining units and the lateral position determining units engage have gaps in the directions orthogonal to the position determining directions to absorb the thermal expansion caused by a rise in the temperature of the image forming mirror when the position determining units engage with the holes.

Abstract: An electrostatic spray device that maintains a consistent charge-to-mass ratio in order to maintain a consistent target spray quality is disclosed. During steady state conditions, the high voltage power supply adjusts the output voltage level in response to changing environmental and/or operating conditions. During transient conditions such as start-up, shut-down and changing flow rate conditions, the high voltage power supply ensures that the charge-to-mass ratio is maintained. During, start-up, for example, the high voltage power supply charges the high voltage electrode to a predetermined voltage level before the product is delivered to the charging location. During shut-down, the product delivery is stopped before the high voltage power supply shuts off power to the high voltage electrode, and during changes in product flow rate, the voltage level of the high voltage electrode is adjusted to maintain a consistent charge-to-mass ratio.

Abstract: A by-product mixture produced when polycrystalline silicon is deposited on a base material in a CVD reactor is made to react with chlorine to form a tetrachlorosilane (STC) effluent in a chlorination reaction vessel, and the tetrachlorosilane (STC) distillate is made to react with hydrogen in a hydrogenation reaction vessel to be converted into trichlorosilane (TCS). In the chlorination step, poly-silane contained in the above described by-product mixture can be efficiently recycled as a raw material for producing the polycrystalline silicon, which can enhance a yield of the production process. In addition, in the chlorination step, methyl chlorosilanes having boiling points close to TCS are hyper-chlorinated to be converted into hyper-chlorinated methyl chlorosilanes having higher boiling points, which facilitates the hyper-chlorinated methyl chlorosilanes to be separated into high concentration, and reduces carbon contamination of the polycrystalline silicon.

Abstract: An electrostatic spray device and a cartridge for an electrostatic spray device that reduce the occurrence of electrically induced emulsion product separation are disclosed. The device and/or the cartridge may reduce electrically induced emulsion product separation by providing a conductive high voltage shield substantially around the product reservoir. Alternatively, the device and/or the cartridge may prevent the product located at the charging location from being in fluid communication with the product reservoir so that the product that is being charged cannot flow back into the product reservoir. The device and/or cartridge may alternatively reduce electrically induced emulsion product separation by minimizing the volume of product between the charging location and the exit orifice of the nozzle.
