摘要:
This invention provides a printing head which can prevent an increase in the number of block enable signal lines, and can prevent changes in printing ink density caused by interference due to the relative pressures of nozzles generated in ink discharge, and an image printing apparatus using the printing head. For this purpose, an increase in the number of input signal lines along with an increase in the number of blocks is prevented using a block clock signal or the like instead of a block enable signal as an input signal to the printing head. Three ring counters generate signals having different nozzle driving orders. These signals are selectively used by a ring counter selection signal. Ink is not always discharged from the nozzles in the same output order. This can prevent changes in ink density caused by pressure interference.

A printing apparatus and printing method can realize high-quality printing without degrading the quality of a printed image even when a nozzle restriction function is adopted in addition to a discharge failure complement function. In a printing apparatus using an inkjet printhead having a plurality of nozzles, whether the position of an ink discharge failure nozzle exists at or near the end of a nozzle area which is still usable regardless of the use restriction on the nozzles is detected. The use of a nozzle for complementary printing executed with a nozzle positioned near the ink discharge failure nozzle is controlled in accordance with the detection result.

In order to reduce emission noise, a recording apparatus uses a cycle controller to variably control a transmission cycle, when transmitting recording data to the recording head, and a head controller to control the recording head based on the controlled transmission cycle and the recording data. By varying the data transfer cycle of data to the recording head, the recording apparatus of the present invention makes it possible to suppress a rise in radiation noise peak levels due to overlapping of radiation noise spectra, which in turn weakens the strength of the electric field at certain cycles and makes it possible to reduce radiation noise levels.

A printer which enables flexible printing control to be performed in conformity with the capacity of a memory installed to satisfy the requirements of a user. In this printer, it is first determined whether the additional memory has been installed or not. Then, the printer further examines the total available capacity of the basic memory and additional memory based upon results of the determination, compares the total capacity with an amount of data necessary to perform printing by a single scan using all ink discharge nozzles of a printhead, decides, based upon the results of the comparison, the capacity of a buffer memory for temporarily storing printing data to be transferred to the printhead, and decides to change resolution in the scanning direction or whether to perform printing by multiscan printing using the buffer memory having the capacity decided or perform printing in which printing using all ink discharge nozzles of the printhead is completed by a single scan of the printhead.

An ink jet recording method records a color image on a recording medium while performing a main scan operation by using a first recording head having a plurality of ink eject orifices for ejecting an ink of a first color and a second recording head having a plurality of ink eject orifices for ejecting an ink of a second color. The method includes the steps of dividing a record area of each of the first and second recording heads into a plurality of blocks, and performing a main scan operation a plurality of number of times for the same area of the recording medium by using different blocks of the plurality of blocks of each of the first and second recording heads, thereby sequentially recording a plurality of thinned images of the first color and a plurality of thinned images of the second color. Different thinning mask patterns are used for the blocks of each recording head and the thinning mask pattern for each block is maintained constant during recording on the recording medium.

A high strength hot rolled steel sheet having excellent blanking workability is provided. The composition contains C: 0.050 to 0.15%, Si: 0.1 to 1.5%, Mn: 1.0 to 2.0%, P: 0.03% or less, S: 0.0030% or less, Al: 0.01 to 0.08%, Ti: 0.05 to 0.15%, N: 0.005% or less, and the balance being Fe and unavoidable impurities. More than 95% of the microstructure is formed of a bainite phase in terms of area fraction. Average grain diameters of the bainite phase in a region having a thickness equal to ¼ of the sheet thickness from the surface in the sheet thickness direction is 5 μm or less in an L-direction cross section and 4 μm or less in a C-direction cross section. The number of crystal grains extended in the rolling direction and having an aspect ratio of 5 or more is 7 or less in a sheet thickness center portion.
