Title: Density gradation type color printer
Inventor: NAKA TOSHIYA
IPC: H04N1/46
Filed: 1986-09-10
Abstract: PURPOSE:To attain a density gradation recording with fidelity without selecting an original by using a density gradation level decided by dividing the density in a way that a locus of each ink in a uniform color space is divided equally in quantizing the density of 3-primary color ink. CONSTITUTION:In varying the ink density continuously from the minimum to the maximum value as to each color of the 3-primary color of ink, the density gradation level is decided so that the locus of chromaticity coordinate drawn in the uniformcolor space is divided uniformly. The density gradation decided in this way is stored in a quantization circuit provided in the density level conversion section 2. The density of each color ink inputted by a picture input section 1 is quantized by assigning it to the density gradation level by the quantization circuit independently respectively and outputted as a head drive signal. The head drive signal is converted into a pulse width to drive the head by the pulse width selection circuit provided in the picture recording section 3.

Filed: 1982-12-07
Abstract: PURPOSE:To simplify a work, to shorten a work time, and to ensure safety, by a method wherein a work during changing of a gas type is performed by a switching mechanism. CONSTITUTION:When the voltage of a proportional valve control signal source 2 indicates a maximum value VSMAX, the pulse input of an operational amplifier 3 is determined from the voltage of a middle point between R4 (or R5) and R6 and the voltage of a middle point between R1 (or R2) and R3, and thereby the maximum current of a proportional valve 1 providing a maximum combustion quantity can be varied by means of the R1 (or R2). Thus, if a maximum and a minimum combustion gas amount when a gas type is, for example, 13A are set by the R1 and the R4, respectively, and the maximum and the minimum value of a proportional valve current I when a gas type is 6B are set by the R2 and R5, respectively, setting of the maximum and the minimum value of the proportional valve current I when the gas type is changed by a switch 4 may be easily varied.

Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for a thermal ink-jet head whereby an orifice can be surely worked and a heat generation characteristic of a heat-generating element is made constant. SOLUTION: A wafer is set in an etching apparatus 20. The wafer is etched while a resistance value of a heat-generating resistance body 5 between a common electrode 2 and one separate wiring electrode 4 is monitored by a control device 21. After an orifice penetrates an orifice plate in the lapse of time from a time point t0 when the etching is started to a time point t1, the etching is continued as it is to form a recess 5-1 and thin the heat-generating resistance body 5. When an initial resistance value Ωu (solid line (a)) of the heat-generating resistance body 5 starts to change (solid line (b)) and becomes a desired resistance value Ωa (time point t2), the control device 21 controls the etching apparatus 20 to terminate the etching.  Accordingly, the orifice surely penetrates at one hand and the resistance value of the heat-generating resistance body is set constant at the other hand.

If data is written in the cache area 1a by the write back system, data unwritten in a file device 10 out of stored contents of the cache area 1a is written in the file device 10 through a cache control part 6. The area distribution control part 3 preliminarily obtains the capacity of the area free from trouble in the memory 1 and allocates the cache area 1a and the buffer area 1b on this area of the memory 1 again after processing. Thus, the memory area is allocated again in the online state to reserve the capacity of an asynchronous buffer.
