A ringtrip judging circuit includes a single comparator for comparing a detection value of a ringing current with a threshold value and for outputting the result of the comparison, a threshold value control circuit for supplying the threshold value to the comparator, and a judging circuit for judging ringtrip based on the output of the comparator. During a prescribed period after ringing signal transmission, the threshold value control circuit changes the threshold value in a steplike manner in accordance with the result of the comparison, thereby determining a threshold value greater than a peak value during the prescribed period, and based on it, determines a threshold value for ringtrip judgement and supplies it to the comparator.

An output circuit, for minimizing output idle current fluctuations and improve the output voltage range, has first and second transistors connected to first and second power sources, with a plurality of diodes connected to control terminals of the first and second transistors. The output circuit further includes a third transistor having a first terminal connected to the second power source and a second terminal connected to a predetermined position among the plurality of diodes. A predetermined voltage is applied from the diodes to the control terminal of the first transistor when the third transistor is saturated, to bring a level of an output of said output circuit close to a level of the second power source. A fourth transistor, a fifth transistor, a first resistor, and a capacitor are also provided. The forth transistor has a control terminal connected to an output of a differential circuit, and a first terminal connected to the second power source through the first resistor as well as to the control terminals of the third and fifth transistors. A second terminal is connected to the first power source, with the fifth transistor having a first terminal connected to the second power source and a second terminal connected to the control terminal of the second transistor. The capacitor is connected between the control terminal of the fourth transistor and the second terminal of the fifth transistor. This output circuit also limits the output voltage without changing the impedance of the high-impedance input.

An ink jet printing apparatus and a print head recovery method are provided which effectively execute a preliminary ejection to eject ink not contributing to image printing from nozzle opening of the print head to maintain the ink ejection performance in good condition. The ink in the print head is heated to a first temperature, at which a first preliminary ejection is executed. Then, when the ink temperature falls to a second temperature, which is lower than the first temperature, a second preliminary ejection is executed.

A dew formation testing device has an adjustment tank capable of adjusting the temperature and humidity of air to predetermined temperature and humidity, a testing tank installed separately from the adjustment tank and having a sample base that has a mounting surface, onto which a testing sample W can be placed, and that is capable to cool the mounting surface, and ducts that link the adjustment unit and the testing tank. The testing tank is provided with an air guide member that, when air flowing into the testing tank through the duct flows onto the sample base from a side of the sample base, guides the air in the direction tilted downward at a predetermined angle, the guidance being performed at a position right above the sample base at an end thereof which is on the upstream side of the air flow.

An ionomer resin composition according to the present invention is obtained by bringing a functional group-containing olefin copolymer (A) having a structural unit derived from a cyclic olefin in the range of 10 percent by mol or more and having a group derived from an acid and/or a derivative thereof as the functional group into contact with a metal compound (B). A shaped article having well-balanced two excellent properties of the optical characteristics and the moisture permeability can be formed by using the ionomer resin composition.
摘要:
The order of the arrangement of ejection opening arrays of two types of ink overlapping in reciprocating scan is decided as follows. An ejection order is decided so that the case where the fixing areas of a main droplet and a satellite are different (dot area is increased) in the forward and backward scan first occurs. By this configuration, the area of the dot and the portion in which different colors are generated due to the difference in the overlapping order in the reciprocating scan can be reduced, compared with the case where the arrangement order is opposite to the above-described case. As a result, a difference in color between areas for which printing is completed by the reciprocating scanning is reduced and thus color unevenness of a printed image can be reduced.
