摘要:
An ink jet printing apparatus and printing method are provided that can, without the addition of a special structure, suppress density imbalance between the print images formed by ink ejected from each of the ejection ports formed on a print head. As for the plurality of ejection ports, one portion of them are established as multiple impact ejection ports that form multiply impacted pixels at which the number of times ink is impacted at the same area is greater than at other pixels of the print area. And, print control is carried out such that more multiply impacted pixels are printed at print areas printed using ejection ports at the ends of the print head than at print areas printed without using ejection ports at the ends of the print head.

A laser device includes a cavity and a control portion. The cavity has an optical amplifier, a wavelength selectable portion having a changeable transmission wavelength range, and a mirror. The control portion controls the wavelength selectable portion so that the transmission wavelength range of the wavelength selectable portion is changed to a given range. The control portion controls the wavelength selectable portion so that the cavity outputs a desirable lasing wavelength light and optical intensity of the desirable lasing wavelength light is a given value, after controlling the wavelength selectable portion so that the cavity outputs the desirable lasing wavelength light.

The hard coat layer-forming composition of this invention includes (A) composite oxide fine particles with a mean particle diameter of 1 to 200 nm, containing titanium, tin and optionally silicon, and with a rutile-type crystal structure, (B) an organosilicon compound represented by the formula R1aR2bSi(OR3)4−(a+b) and/or a hydrolyzate thereof, and (C) a cyanamide derivative compound. A hard coat layer formed from the composition not only is excellent in transparency, scratch resistance, adhesion property, weathering resistance, impact resistance, etc. but also can enjoy no coloration or little coloration, particularly in bluing or yellowing, upon exposure to or irradiation with ultraviolet rays, even if an antireflection film is provided.

The object of this invention is to provide a printing apparatus and printhead temperature retaining control method capable of suppressing power consumption, and reducing degradation in image quality. To achieve the object, a printing apparatus for printing an image on a printing medium by discharging ink, executes the following processes. A first temperature adjustment process is executed to adjust the printhead temperature to a first adjustment temperature during the non-printing period in which preparation for printing the image is executed by discharging ink from the orifices. Additionally, a second temperature adjustment process is executed to adjust the printhead temperature to a second adjustment temperature during a printing period in which the image is printed on the printing medium by discharging ink from the orifices. The process is executed while providing a quiescent period without printhead temperature adjustment between the first and second temperature adjustment processes.

Spherical composite particles are formed of inorganic fine particles and resin fine particles joined together, and an average particle diameter is in the range from 1.1 to 100 μm, in which the average particle diameter of the inorganic fine particles is in the range from 5 to 600 nm and the average particle diameter of the resin fine particles is in the range from 10 to 500 nm. The inorganic fine particle and the resin fine particle have almost the same size, and the hardness, softness, and adaptability when spreading on a skin can finely be adjusted as desired in a wide range according to the contact feeling required for the cosmetics in which the particles are blended.

In a lead frame board, while a heat radiation wall member formed by a resin having a relatively high thermal conductivity is provided in a low heat-resistance heat generating component mounting region where a low heat-resistance heat generating component is mounted, heat block wall members formed by resins having relatively low thermal conductivities are provided in a high heat-resistance heat generating component mounting region where a high heat-resistance heat generating component is mounted and in a non-heat generating component mounting region where a non-heat generating component is mounted. Thus, heat block is performed between the low heat-resistance heat generating component mounting region and the high heat-resistance heat generating component mounting region and non-heat generating component mounting region, and a heat radiation function is enhanced in the low heat-resistance heat generating component.

摘要:
There are provided an inkjet printing apparatus and an inkjet printing method, whereby, the temperature of a print head is controlled and the ejection volume of ink to be ejected is stabilized to print a high-quality image, even at a high printing duty. Based on print data, an ejection number of ink to be ejected into a unit printing area is counted. The print head is heated to a target temperature that is raised in consonance with an increase in the count value.

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.
