摘要： An ink-jet recording device is capable of correcting a recording position due to a leaning of a printing head and correcting of driving timing between multiple printing heads. Each nozzle row of a printing head is classified into multiple nozzle groups, and the driving timing of the nozzle groups other than the nozzle group serving as a reference of correction of the multiple nozzle groups is adjustable to correct for any leaning of the printing head. Moreover, in the event of performing the driving timing between printing heads, the driving timing of a non-reference printing head is adjustable relative to a reference printing head employed for leaning correction of multiple printing heads.

摘要： [Object] A monitoring device for precisely taking out light for a monitor and having a simple structure and able to be made compact is provided. [Means for Resolution] A lens array 17 is attached to the tip face of an optical fiber array 12 holding optical fibers 14, 15 in parallel. A lens 19 is arranged in the lens array 17 so as to be opposed to the end face of each of the optical fibers 14, 15. A triangular prism 13 is arranged in front of the lens array 17. An incident-emitting face 22 of the triangular prism 13 is inclined with respect to the lens array 17. Signal light L emitted from the optical fiber 14 is converted into parallel light by the lens 19, and is incident to the triangular prism 13. After the signal light L is then totally reflected on the reflecting face 20, the signal light L is incident to a reflecting face 21. The incident angle of the signal light L incident to the reflecting face 21 is slightly smaller than a critical angle of the total reflection. The signal light L is leaked from the reflecting face 21 to the exterior by a constant ratio κ. Accordingly, the amount of the signal light L can be calculated by measuring this leak light La.

摘要： A sheet material for the tube 10 includes: a core material 10b; and a sacrifical corrosion material 10c clad on one face of the core material 10b which becomes an outside of the tube 10. A sheet material for the fin is a bare aluminum material on which a brazing filler metal is not clad. A mixture composition 10e, in which powder of a brazing filler metal and flux are mixed with each other, is coated on the outside of the tube 10. The tube 10 and the fin are brazed to each other with this mixture composition 10e. Even after the completion of brazing, the sacrifical corrosion material 10c remains on the outside of the tube 10.

摘要： A flaky, fine powder comprising a flaky substance as the base and silica particles covering the surface of the base, aimed at reducing the glossiness of the base caused by the irregular reflection of light on its surface and improving the slipperiness. In particular, the powder comprises a flaky base substance such as natural mica and silica particles deposited on the base surface, wherein the silica particles may be optionally further immobilized by the hydrolysate of alkoxysilane or silica gel. The flaky fine powder is produced either by the adding alkoxysilane to a dispersion containing a flaky substance and silica particles and hydrolyzing it, by adding a silicic acid solution to the dispersion and gelling it, or by adding a combination of alkoxysilane and silicic acid solution. The powder can be compounded with various ingredients and is particularly useful with cosmetics.
