摘要： In an ink ejection type recording device in which expansion of bubble ejects an ink droplet from a nozzle toward a recording medium, a heater formed in an ink channel is applied with a pulse of voltage by a driver circuit. The pulse of voltage is determined so that the surface of the heater in direct contact with the water-based ink is rapidly heated to a temperature causing to invoke caviar-wise nucleation of the ink that is in direct contact with the surface of the heater. Expanding bubbles resulting from the caviar-wise nucleation ejects an ink droplet from the nozzle, wherein the heater is heated at a heating speed in a range from 1.times.10.sup.8 .degree. C./sec to 5.times.10.sup.8 .degree.C./sec, and the surface of the heater is heated up from a room temperature to a temperature substantially equal to 320 C within a period of time ranging from 0.6 to 3 .mu.sec. By heating the heater under these conditions, the ink in contact with the heater starts boiling with a high boiling pressure, the generated bubble has a large volume, and thus the bubble can generate pressure sufficiently large to eject the ink droplet.
摘要翻译：在喷墨式记录装置中，气泡的膨胀将墨滴从喷嘴喷射到记录介质，形成在墨水通道中的加热器被驱动电路施加电压脉冲。确定电压脉冲，使得与水性油墨直接接触的加热器的表面被快速加热到引起与加热器表面直接接触的油墨的鱼子酱成核的温度。由鱼子酱成核引起的膨胀气泡从喷嘴喷射墨滴，其中加热器以1×10 8℃/秒至5×10 8℃/秒的加热速度加热，加热器的表面在0.6〜3微秒的时间内从室温升温至基本等于320℃的温度。通过在这些条件下加热加热器，与加热器接触的墨水以高沸点开始沸腾，产生的气泡体积大，因此气泡可产生足够大的压力以喷射墨滴。

摘要： An ink ejection printer includes an ink channel filled with ink, a nozzle which brings the ink channel into fluid connection with an outside atmosphere, and a thermal resistor formed in the ink channel near the nozzle. The thermal resistor received a pulse of voltage, whereupon the thermal resistor rapidly heats so that a portion of the ink in the ink channel is rapidly vaporized by subcool boiling, which is caused by swing nucleation, to produce a bubble, expansion of the bubble ejecting an ink droplet from the nozzle. With the thermal resistor, boiling starts within 2 .mu.S after application of the pulse of voltage begins. The pulse of voltage is applied to the thermal resistor for a duration of 3 .mu.S or less. The bubble generated by application of the pulse of voltage to the thermal resistor disappears without the thermal resistor generating secondary bubbles. The bubble generated by application of the pulse of voltage of the thermal resistor disappears within 11 .mu.S after application of the pulse. Energy required to generate the bubble is 4 .mu.J/50.times.50 .mu.m.sup.2 or less.
摘要翻译：喷墨打印机包括填充有墨水的墨水通道，使墨水通道与外部气氛流体连接的喷嘴，以及形成在喷嘴附近的墨水通道中的热敏电阻器。热敏电阻器接收到电压脉冲，于是热敏电阻器迅速加热，使得油墨通道中的一部分油墨通过由摆动成核引起的过冷沸腾而迅速蒸发，从而产生气泡，弹出气泡的膨胀来自喷嘴的墨滴。使用热敏电阻，在施加脉冲电压开始后，沸点开始在2μS以内。将电压脉冲施加到3μS以下的持续时间。通过将电压脉冲施加到热电阻而产生的气泡消失，而没有热电阻产生二次气泡。通过施加脉冲电压产生的气泡在施加脉冲后的11μs内消失。产生气泡所需的能量为4亩/ 50×50平方米以下。

摘要： In an ink jet printer, a belt-type preheating unit 2 pressingly heats a recording sheet 6 while transporting the recording sheet in a transport direction B on a belt. A suction transport device 3 is positioned downstream of the belt-type preheating unit 2 in the transport direction B. The suction transport means transports, on its transport belt, the recording sheet 6 heated by the belt-type preheating unit 2 in the transport direction B while fixing the recording sheet onto the transport belt by a vacuum suction. An ink jet print head, positioned confronting the suction transport device 3, records images by ejecting water-based ink onto the recording sheet which is being transported by the suction transport device.
