The present invention provides laser beam micro-smoothing for laser annealing systems. Laser beam micro-smoothing comprises shifting a laser beam in the direction perpendicular to the scanning direction (y) of a laser annealing system, while holding the laser beam fixed in the direction of scanning (x). The shifting may be accomplished, for example, with a pair of micro-smoothing mirrors. The shifting smoothes out small-scale inhomogeneities in the profile of the laser beam and prevents microscopic stripes associated with prior art laser annealing systems. Because the shifting occurs only in the direction perpendicular to the scanning direction (y), the laser annealing process in not adversely affected.

The present invention relates to print controlling apparatus and print controlling method. Stop of print operation in the middle of printing is prevented from causing a stripe or unevenness on a print medium. A print control apparatus for creating print data for printing with a printing apparatus, and transmitting the created print data to the printing apparatus, includes: judging means for judging whether to transmit print data by page to the printing apparatus; and transmission controlling means for transmitting the print data by page when the judging means judges to transmit the print data by page, and transmitting each print data, into which the print data for a page is divided, when the judging means judges not to transmit the print data by page.

A communications apparatus is shown having an imaging device for capturing an image, and a flash for lighting an image to be captured. Also shown is the use of the apparatus. Software for matching a flash performance to other functions of a device is also shown. A radio communications apparatus embodiment is shown that comprises an imaging device including an image sensor and a rolling shutter, and a flash unit. The flash unit is operated at a certain flash frequency, and an exposure time is determined according to the flash frequency so that the image sensor is uniformly exposed by the rolling shutter during the determined exposure time.

An eavestrough cover designed to cover the upper front wall portions of a conventional eavestrough and which has a finish to minimize streaking or staining. The eavestrough cover snaps into position on the eavestrough.

The purpose of the present invention is to provide a carboxymethyl cellulose salt for electrodes of nonaqueous electrolyte secondary batteries, which is capable of achieving a good balance between prevention of defects such as streaks and pin holes on a coated electrode surface and excellent bonding strength to a collector or excellent bonding strength between active materials. A production method which comprises: (1) an alkali cellulose formation reaction step wherein a mixed solvent that contains an alcohol having 3 or less carbon atoms and water at a mixing ratio (mass ratio) of from 75:25 to 95:5 is used and the alkali concentration relative to water is 25-40% by mass; (2) an etherification reaction step wherein a reaction is carried out in the presence of an excess alkali of 0.2-0.5 mol per unit of an anhydroglucose of the cellulose; (3) a neutralization step wherein an acid is added after the etherification reaction so that the pH of the reaction mixture is adjusted to 6.0-8.0; and (4) a heating step wherein the mixed solvent is removed and an alkali is added after the neutralization step so that the pH of the reaction mixture is adjusted to 8.0-9.0, and subsequently, a heat treatment is carried out at 40-70 DEG C for 30-120 minutes.

This invention provides a fluorophosphate optical glass molding equipment, including mold. Mold described composed by the end of mold, side die and block, in Mold also provided with cooling flat, air vents are installed on the flat. Fluorophosphate optical glass molding apparatus molding methods includes the following steps: 1) glass fluid flows out of the material tube and flow into Mold; 2) in Mold the glass fluid flow through the upper surface cover the cooling flat, inert gas through the air vents on the cooling flat blow to glass solution surface, so as soon as cool glass liquid for molding. The invention set cooling flat on the mold, through air vents blowing inert gas, so as soon as cooling liquid glass, to avoid the glass at high temperatures causing the volatile stripes, ensuringthe quality of products; In addition, the invention uses graphite mold to avoid corrosion.
