IPC: B41J2/175
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To predict the lifetime of a print head by determining the quantity of ink jetted from an ink jet head during a predetermined interval, deriving the quantity of accumulated air for update using the quantity of ink thus determined and then updating the stored air accumulation parameters based on the quantity of accumulated air to be updated. SOLUTION: During single swash print operation of a print head 50, a microprocessor 60 calculates and stores the count of jetted small ink droplets, the measurement of average temperature of a template in the print head 50, and the print density. At the same time, the template temperature is accessed and the air discharge rate is calculated based on the air solubility inclination parameters and the constants stored in a memory chip 54 within the print head 50 and then the quantity of air to be discharged is calculated from the air discharge rate. Subsequently, a stored quantity of accumulated air is updated using the quantity of air to be discharged and the latest quantity of accumulated air is compared with a critical value. When the latest quantity of accumulated air is equal to or larger than the critical value, a print head lifetime alarm is delivered.

Abstract: PROBLEM TO BE SOLVED: To join an article from a branch stream line with a predetermined virtual space set on a main stream line accurately by compensating the timing at which the article is taken out from the branch stream line in accordance with a speed of the main stream line when the main stream line is decelerated or accelerated. SOLUTION: When a main stream line 2 is operated while decelerating or accelerating, a slide amount for the conveyance direction of the main stream line 2 of an article to be taken out from a branch stream line 1 on the main stream line 2 in accordance with its speed differs. For this reason, the timing at which the article is taken out from the branch stream line 1 in accordance with a speed of the main stream line 2 should be compensated to put the article in a central part of a predetermined virtual space. For example, the timing at which the article is taken out from the branch stream line 1 in accordance with a distance from a position of the predetermined virtual space when the main stream line 2 begins its deceleration to a position where the predetermined virtual space opposes to the article to be joined is compensated.

Abstract: PURPOSE:To obtain a DC power supply equipment capable of instantly detecting a momentary interruption regardless of the form of power stop in primary power supply by providing current transformers in series to each power line and by providing a field effect transistor and a drive circuit. CONSTITUTION:When the power supply of the primary power supply 1 is short- circuited and interrupted, no current is detected at current transformers 17, 18 and 19, and it is judged as momentary interruption in a comparison circuit 26, and a signal is sent to a constant power load 9. Also, when this momentary interruption occurs in open state, the current detected by the current transformers become extremely small compared to that of normal operation, thereby without delaying in detecting the momentary interruption. Moreover, if the momentary interruption occurs during open state, the capacitor of a filter circuit 2 has a danger of creating a natural discharge. Therefore, if the momentary interruption is detected by the comparison circuit 26, a signal is sent also to the drive circuit 27, by which the field effect transistors 28, 29 and 30 are driven and the line is short-circuited.
