摘要:
An ink-feeding device is provided in which the pressure applied to the ink in the printing head can be adjusted arbitrarily irrespective of the relative positions of the ink container and the printing head. Inside the sub-tank 80, a pressure-adjusting pump 82 is installed for applying a suitable pressure to many nozzles 22Kn of the printing head 22K. This pressure-adjusting pump 82 is placed a little above the bottom face of the sub-tank 80 at a prescribed distance from the bottom face. Thereby the pressure-adjusting pump 82 is immersed in the ink held in the sub-tank 80. A drive unit 83 for driving the pressure-adjusting pump 82 is placed above the sub-tank 80. On the upper wall of the sub-tank 80, an air-vent valve 84 is fixed to bring the inside pressure in the sub-tank 80 to an atmospheric pressure. The inside pressure in the sub-tank 80 is made equal to the atmospheric pressure by opening the air-vent valve 84.

A cable holder includes a plurality of cable holding portions and a stopper. The plurality of cable holding portions is arranged under an apparatus body of an apparatus that is connectable to another apparatus via a cable, the cable to fit in the plurality of cable holding portions. The stopper is disposed at the plurality of cable holding portions to hold the cable fitted in the plurality of cable holding portions. The plurality of cable holding portions includes outlets communicated with an outside of the cable holder and arranged at different positions from each other.

A high heat-resistant member includes a graphite substrate including isotropic graphite and a carbide coating film including a carbide, such as tantalum carbide, and covering a surface of the graphite substrate, the carbide coating film having a randomly oriented isotropic grain structure in which crystallites having a size indexed by a full width at half maximum of a diffraction peak of an X-ray diffraction pattern of not more than 0.2° from (111) planes are accumulated at substantially random. The orientation of the carbide coating film is determined by whether degree of orientation (F) in any Miller plane calculated based on an XRD pattern using the Lotgering method is within a range from −0.2 to 0.2.

An image forming apparatus includes an apparatus body, a recording head, a head tank, a displacement member, an air release unit, a main tank, a liquid feed device, a body-side detector, and a supply controller. The supply controller controls a normal filling operation to start feeding liquid from the main tank to the head tank without opening the air release unit when a consumption amount of the liquid in the head tank is a threshold amount or greater, and stop feeding the liquid from the main tank to the head tank when the body-side detector detects an arrival of the displacement member at a normal fill position. When the body-side detector detects the displacement member at a start of the normal filling operation, the supply controller corrects the normal fill position to a position at which the liquid feed device can feed the liquid to the head tank.

Provided is a convenient leak detector which has high detection sensitivity and can quickly start a leak test after the start of vacuuming a test piece, without impairing the capabilities such as fast response to helium gas. The leak detector includes a mass spectrometer tube configured to detect a search gas and a turbo-molecule pump which has a plurality of stages rotors and stators alternately arranged in a housing, the rotors attached to a rotary shaft, and includes a drive source configured to rotationally drive the rotary shaft. An intake port communicating with a test piece TP and a connection port to which the mass spectrometer tube is connected are opened at positions away from each other in a wall surface of the housing, the wall surface facing a rotor of the uppermost stage.

An image forming apparatus, includes a liquid jet head; a container main body; an air opening mechanism configured to open and close an air opening path in the container main body. The air opening mechanism includes a holding part, and an opening member movably provided at the holding part. The opening member includes an air communicating path, a filter member, and an air room. An opening cross-sectional area of the air room in a direction perpendicular to an air flow-in direction is greater than an opening cross-sectional area of the air communicating path in a direction perpendicular to an air flow-in direction.
