Abstract: An electric pump draws and discharges fluid. When the fluid receives heat from the pump, the fluid has a saturation vapor pressure that can surpass the pressure of fluid that is drawn into the pump and is lower than the pressure of fluid discharged from the pump. The pump includes an electric motor; a pump section that is driven by the electric motor to draw, pressurize, and discharge the fluid; and a housing for accommodating the pump section. The housing defines a motor chamber that accommodates the electric motor. The pressure in the motor chamber is equal to the pressure of fluid that is discharged from the pump section. Therefore, the pump prevents fluid in the motor chamber from vaporizing.

Abstract: A pressure sensitive sensor is provided that includes a net braid member formed by knitting a plurality of insulating yarn strands, such as an aramid fiber, interposed between an elastic electroconductive tube and a central electrode member. The elastic electroconductive tube and the central electrode member are brought into electrical contact with each other through the gap portion of the mesh of the net braid member at a pressure point, and pressure is detected.

A waveform generator generates a plurality of waveform signals, including a waveform signal extending over two adjacent print cycles, and a waveform selector selects and outputs to the ink-jet head one of a plurality of waveform signals, based on whether dot data for two adjacent print cycles indicates ink ejection.
