An ink supply device includes an ink tank for containing ink inside and a tank holder for holding the ink tank in a detachable manner. The tank holder includes a control tank, a circulation needle, and an air supply needle. The control tank allows the ink and air to circulate between the control tank and the ink tank so that the internal pressure of the ink tank attached has a predetermined value.

A light-alloy wheel is cast using an apparatus wherein cores are moved by a cotter via a sliding mechanism. A sliding portion is isolated from molten metal so that locking at the sliding portion is unlikely to occur. The sliding mechanism can be of a small size and is disposed in an interior of a mold top segment with a relatively large gap between the cotter and the mold top segment. The gap assures a good heat dissipation from the mold top segment. In a molding method conducted using the apparatus, the cores may be positioned at a retracted position and extended before the molten metal has solidified to thereby remove blow holes in a cast wheel.

An electromagnetic cross valve is provided for selectively connecting a nozzle with an ink liquid supply conduit and an ink liquid drain conduit. When the nozzle is connected with the ink liquid drain conduit, ink liquid remains in the nozzle in such a manner that the ink liquid is filled to the tip end of the nozzle or the orifice of the nozzle.

Cloth is successively conveyed by a supply roller and a take up roller over a platen which opposes an ink jet head selectively jetting ink. The platen has an opening formed at a surface opposing to the ink jet head, and an air suction opening behind the opening of the platen is connected to an air suction unit through an air path. At the time of dyeing, fluff on the surface of the cloth opposing to the ink jet head is sucked and laid down on the surface of the cloth by air suction by the air suction unit, and ink is appropriately jetted to the surface of the cloth from the ink jet head. Therefore, ink jet is not hindered by the fluff on the surface of the cloth at the time of dyeing. Therefore, ink drops can reach the desired position on the surface of the cloth, and satisfactory dyeing without any distortion in patterns is performed.

In a non-printing state, a cap is moved toward an ink jet nozzle of a head, for sealing the same. Immediately before the cap comes into contact with the jet nozzle, a gear is rotated by a motor to drive a piston, for sucking air from the interior of the cap by a suction pump consisting of the piston and a cylinder. This sucking operation is continued until the cap comes into close contact with the jet nozzle, for sucking the ink from the head.

A specific number of orifices corresponding to the respective ink colors are provided for the printing head of an on-demand color jet printer in which orifices dealing with respective color ink are divided into orifice groups each being provided with a plurality of orifices. The orifices in the orifice groups dealing with respective color inks are designed to allow the supply of color inks through a plurality of ink paths each being independently provided and having a specific length. This configuration allows the entire system to stably execute a printing operation without being affected by the acceleration force applied to the printing head when driving the printing head at an extremely fast speed, which adversely affects the supply of ink to these orifices.

An ink jet system printer includes a capping mechanism for covering a printer head when a carriage is located at a stand-by position. The capping mechanism includes a cap member supported by a slidable plate. The slidable plate is shifted toward the printer head as the printer head moves to the stand-by position through the use of links, whereby the cap member covers the nozzle portion included in the printer head. That is, the slidable plate is shifted by the travelling force of the carriage and, therefore, a separate drive source is not required for the slidable plate.
摘要:
An object of the present invention is to provide an ultrasonic urinary volume sensor capable of estimating a urinary volume in the bladder accurately corresponding to any particular individuals and/or conditions thereof by incorporating a space time series processing method allowing for an accurate estimation of the urinary volume in the bladder in association with the particular individuals and/or conditions thereof. An ultrasonic urinary volume sensor of the present invention comprises: a probe 1 having a plurality of ultrasonic oscillators 3 for oscillating ultrasonic waves toward a wall surface of the bladder, which is adhesively placed over a body surface in an abdominal section via an ultrasonic wave transmission medium interposed therebetween; and a processing section 2 for detecting and processing reflective echoes of the ultrasonic waves from the wall surface of the bladder, which have been oscillated by the plurality of ultrasonic oscillators 3 of the probe 1, wherein the plurality of ultrasonic oscillators 3 is disposed along a direction of expansion of the bladder.

Various ink heads with holes different in diameter can be attached to a carriage of an inkjet printing apparatus. A CPU detects the type of an ink head attached, by states of signals on signal lines. The CPU executes a printing operation in a resolution corresponding to an amount of ink discharge based on a result of detection. When one of various ink heads having a plurality of holes and having the same pitch between the holes as that of one another ink head is attached, the printing operation is carried out such that the amount of ink discharge is substantially the same for the respective ink heads, in particular, that a relation of recording paper feed amount X=(C/(P1/P−1)×P1+P2 is satisfied, further in particularly, C/(P1/P2)=a positive number. Ink heads provided with a plurality of holes arranged with the same interval may also be attached. Thus, various ink heads can be attached to the carriage to provide a plurality of resolutions and high quality prints.
