Title: Operation method of ink jet recorder
Inventor: TERASAWA HIROHARU
IPC: B41J2/185
Filed: 1985-10-01
Abstract: PURPOSE:To minimize the wasteful consumption of ink by always keeping the steady discharge of ink, by a method wherein ink is idly discharged into a cap when a printing command is not generated for a fixed time and the ink is idly sucked when its frequency has reached a fixed number of times. CONSTITUTION:When a power source is turned on, in the case of no printing command for a fixed time, each ink discharge port is driven and ink is idly discharged into a cap 7, that is, its inside space 10. When the number of times of this idle discharge has reached a fixed number of times, the ink generated in the cap 7 by the idle discharge is idly sucked to flow the ink into a suction pump 8. Thereby, the amount of ink in the cap is controlled to not more than a fixed amount and when the printing command is not generated for a more longer fixed time, the power source of the recorder is operated to be turned off. Thereby, even when ink of high dye density is used, the jetting character is good and the steady printing quality can be kept. Then, the wasteful consumption of ink can be minimized.

Title: Display device
Inventor: DOI WATARU
IPC: G09G5/10
Filed: 1988-08-31
Abstract: PURPOSE:To improve, specially, the brightness of only a single-shot signal by increasing the brightness of the display device when detecting dissidence between two successive data among output serial data. CONSTITUTION:Parallel data read out of a memory plane 12 is inputted from a shift register to a parallel-series converting circuit 13, where the data is shifted with a dot clock from a terminal 14 and outputted as serial data from an output terminal at one end. When the data of a spectrum part is inputted to the output terminal QD of the parallel-series converting circuit 13, its output data is 1, but this data is a single-shot signal, so data before and after said data, i.e. data at output terminals QE and QC are 0. The outputs of exclusive OR circuits 17 and 18 and '1' and a dissidence detecting circuit 21 detects their dissidence. Then its dissidence detection output is added to the data at the output terminal QD, so the current brightness of the display device 11 is high.

Abstract: PURPOSE:To generate a stable modulation signal in the whole region having constant modulation frequency by preventing the change of the direction of counting of a counter outputting the address of the modulation signal at the time of the rotation and changeover of the phase of an output from an inverter. CONSTITUTION:A frequency command is inputted to a function generator 7, and an output from the function generator 7 is converted into clock pulses by a V/F converter 8. The clock pulses are changed into a phase signal by a counter 9, and added to an output from a counter 2 by an adder 10 and turned into the address of a ROM4. Data corresponding to a sine-wave one period are written to a ROM3 as a reference signal and data corresponding to a triangular-wave twelve period to the ROM4 as a modulation signal respectively, and these data are compared by a comparator 6 and a PWM signal is outputted. An output from a polarity discriminating circuit 11 is introduced only to the counter 2, thus changing only the direction of counting of the counter 2 at the time of the changeover of forward or reverse rotation, then inverting the phase rotation of the reference signal.

Abstract: PROBLEM TO BE SOLVED: To rapidly perform inspection by mutually comparing the image data of two patterns where the distance between them is integer multiples of resolution when the pitch of a pattern is not integer multiples of the resolution of image processing. SOLUTION: Since the least common multiple between a pitch 211 μm of an electrode pattern and a resolution 5 μm of image processing is 1,055 μm, each five electrode patterns are grouped. Then, the each corresponding five image data, Pα1-Pα5, Pβ1-Pβ5, and Pγ1-Pγ5 are also grouped, Pα1 is compared with Pβ1 that is separated by 1,055 μm to obtain synthesis data Dαβ1. Then, synthesis data Dαβ1 is obtained from Pα2 and Pβ2, and synthesis data Dαβ5 is obtained similarly successively. In this case, when the image data Pα4 has a deficit C, remaining data NC is generated in the synthesis data Dαβ4.  In this manner, when the remaining data that differs from other synthesis data is generated in the illustrated synthesis data Dαβ1-Dβγ1, it is judged that the data is defective.
