摘要:
An ink/print media discriminating portion discriminates kind of ink to be used in an apparatus on the basis of information of kind of the ink or a printing medium input by a user. The discrimination information is fed to a thermal energy generation amount control portion. The thermal energy generation amount control portion sets a driving condition, such as a pulse width of a drive pulse or the like corresponding to the kind of the ink represented by the discriminated information, is set in a head driving portion.
摘要:
A vacuum processing method that includes placing an article to be processed in a reaction container and simultaneously supplying at least two high-frequency powers having mutually different frequencies to at least one high-frequency electrode to generate plasma in the reaction container by the high-frequency powers introduced into the reaction container from the high-frequency electrode(s), thereby processing the article. The frequencies and power values of the at least two high-frequency powers supplied satisfy required relationships.

A vacuum processing method comprises placing an article to be processed in a reaction container and simultaneously supplying at least two high-frequency powers having mutually different frequencies to the same high-frequency electrode to generate plasma in the reaction container by the high-frequency powers admitted into the reaction container from the high-frequency electrode so as to process the article to be processed. In the method, at least the high-frequency power having a frequency f1 and the high-frequency power having a frequency f2 are used and satisfy the following two conditions as the high-frequency powers: 250 MHz≧f1>f2≧10 MHz 0.9≧f2/f1≧0.1.
摘要:
In an ink-jet printing apparatus, upon turning on the power source of the printing apparatus, a stirring operation of ink in the main tank is performed for a given period of time, and during subsequent printing operation, the stirring operation in the main tank is performed for the given period at every predetermined elapsed time period. By this, the printing operation for a long period can be performed employing ink having a water insoluble dye without causing a problem of admixing of bubble or so forth caused by stirring of the ink in the main tank.

Disclosed herein is an ink-jet printing method comprising ejecting inks by an ink-jet printing apparatus to conduct printing on a cloth, wherein a cloth having water absorption of at least 3 seconds as determined by a method (dropping method) prescribed by JIS L-1096 A is used as said cloth, a shot-in ink quantity per unit area of the cloth is changed to conduct gradation control, and a shot-in ink quantity per ink upon printing of the maximum color density is adjusted within a range of from not less than 8.0 &mgr;g/mm2 to not more than 35.0 &mgr;g/mm2.

For stably obtaining high-quality images with good cleaning properties, with neither occurrence of uneven scraping of a surface layer of a light receiving member nor fusion of a toner, and without occurrence of an image defect even without provision of a heater, the wear loss of the surface layer of a non-monocrystalline hydrogenated carbon film is made not less than 1 Å/10,000 sheets nor more than 10 Å/10,000 sheets after completion of copying processes of A4-size transfer sheets, each copying process including developing an image on a light receiving member with a developer having an average grain diameter of 5 to 8 &mgr;m, then transferring the developer image onto a transfer medium, and thereafter scrape-cleaning the surface of the light receiving member with an elastic rubber blade having the hardness of not less than 70 nor more than 80.
摘要:
An ink-jet printing apparatus restricts fluctuation of the printing density due to coagulation and settling of a coloring agent in a water based ink, in which a water insoluble coloring agent or a coloring agent having low water solubility is dispersed. By this, movement of the ink caused due to difference of specific gravity caused by coagulation of the coloring agent or so forth in an upper passage to a lower passage can be restricted to successfully prevent increasing of difference of ink density.

Disclosed herein is an ink-jet printing cloth comprising a thickening surfactant in an amount of from 0.1 to 30% by weight and an aqueous auxiliary for thickening the thickening surfactant in an amount of from 0.1 to 30% by weight, based on the weight of the cloth, respectively.
摘要:
In a helicopter blade aerofoil, upper and lower surfaces thereof are defined by the following coordinates, and the leading edge profile of the aerofoil is defined by the following leading edge radius and center of circle. Thus drag divergence Mach number Mdd and maximum lift coefficient Clmax can be increased and the level of noise can be reduced.______________________________________X/C Yup/C Ylow/C______________________________________0.00000 0.00000 0.000000.00250 0.00781 -0.005580.00500 0.01131 -0.007650.00750 0.01423 -0.008740.01000 0.01660 -0.009640.01750 0.02224 -0.011560.02500 0.02658 -0.012760.50000 0.03585 -0.015680.07500 0.04128 -0.017580.10000 0.04480 -0.019010.15000 0.04893 -0.021130.20000 0.05095 -0.023060.25000 0.05181 -0.024920.30000 0.05200 -0.026470.35000 0.05179 -0.027600.40000 0.05129 -0.028210.45000 0.05038 -0.028270.50000 0.04888 -0.027750.55000 0.04673 -0.026620.60000 0.04393 -0.024910.65000 0.04037 -0.022680.70000 0.03592 -0.019960.75000 0.03052 -0.016820.80000 0.02430 -0.013370.85000 0.01751 -0.009740.90000 0.01046 -0.005970.95000 0.00407 -0.002361.00000 0.00207 -0.00079______________________________________ Leading edge radius r/C = 0.00844, Center of circle X/C = 0.00842, Y/C = 0.00064,
摘要:
An ink absorbent member is prepared for holding an ink stored in an ink storing section in an ink jet cartridge. The ink absorbent member contains not more then 0.20% by weight, on the basis of the member, of a fraction of soluble matters in a liquid containing an organic polar solvent incapable of reacting with the ink absorbent member such as monohydric alcohols or alkyl ethers of polyhydric alcohols.
