摘要:
A nozzle plate to be mounted on an ink jet print head includes a plate body on which is formed a plurality of jet aperture portions from which ink is jetted and a water-repellant film formed on this plate body. The diameter of jet aperture portions formed on the plate body and the diameter of water-repellant film apertures formed on the water-repellant film so as to connect with the nozzle apertures are the same diameter R3, so the ink jet flow can be accurately controlled.

The instant invention has an exemplified object to provide an inkjet head and recording device having such an inkjet head with a simpler structure as achieves higher quality of printing inexpensively than the conventional. The pressure-chamber plate of this invention is slit or divided into a plurality of elements.
摘要:
It is an exemplified object of the present invention to provide an inkjet head, its manufacturing method, and a recording device that can form a high-quality image while preventing an ink leakage. To accomplish the object, an indent is provided at a joint surface of a pressure chamber plate with an adhesive.

An ink-jet head includes a head portion having a plurality of head segments and an ink feeding portion, where ink is supplied such that pipes each have one end connected to the head portion and the other end connected to one of ink feeding paths of the ink feeding portion. The pipes are held by elastic ring-shaped members that are further sidewise held by rigid ring-shaped members and vertically sandwiched between the ink feeding paths and an upper end portion of the head portion.
摘要:
The present invention has an object to provide an inkjet head and a method for manufacturing the inkjet head which not only protects a member at and/or near a surface onto which the nozzle plate is connected (nozzle connection surface), but also shortens the manufacturing time. A protective layer is provided between the nozzle plate and the piezo-electric element, enabling only the protective layer to be polished, protecting the piezo-electric element from being damaged by the polishing when the nozzle connection surface is formed. After the inkjet head is completed, the protective layer prevents ink leakage to the piezo-electric element.

An apparatus for cooling preformed articles, which is capable of very effectively cooling the preformed articles and is, further, capable of sufficiently suppressing or preventing the preformed articles from being locally damaged as a result of coming in contact with each other as they are conveyed neighboring one another in a state of not yet fully cooled. A spray is blown onto the preformed articles 34 conveyed passing through a predetermined conveyer passage 42, a cooling liquid is blown next thereto, and a gas stream is further blown thereto.

A feed-through for feeding electric power to a submerged pump installed in a tank for cryogenic liquefied gases such as LNG and LPG. In the feed-through, a bushing made of an insulating material is inserted in the bushing insertion hole of a flange, and a conductor is inserted in the hollow part of the bushing. A gap between the flange and each end of the bushing insertion hole and a gap between each end of the bushing and the conductor are sealed airtight by seal members. A through-hole is formed in the wall of the bushing, and a space part communicating with the through-hole is formed in the flange. The pressure in the space part of the flange is detected by a pressure detector.
摘要:
When compression molding is performed continuously, lumps of molten synthetic resin (drops), which are supplied by extrusion, are continuously, accurately, and rapidly inserted into plurality of compression molding dies which are rotatingly movable. A method and device for continuously supplying drops into female moldings which are rotatingly movable for manufacturing moldings, wherein synthetic resin in molten condition extruded from an extrusion opening is cut by a cutter attached to a holding mechanism to form the molten resin into drops in a determined quantity, the drops are held and conveyed by the holding mechanism, and the drops are forcibly inserted and supplied into the concaves of the female moldings. At that time the holding mechanism on the rotary-and movable type drop supply is made to approach the rotating molding die and the rotation path of the holding mechanism is made to overlap with that of the molding die within a determined area to make the movement of the holding mechanisms follow that of the molding die.

Maintenance of a wireless base station can be easily performed even when a wireless base station is installed on an electric pole. A maintenance terminal for communicating with a maintenance unit in the wireless base station through a wireless link is prepared for the wireless base station. The maintenance unit receives maintenance information and transmits the maintenance information received to the maintenance terminal, which is monitored by an operator. Also, the maintenance unit receives a control data from the maintenance terminal and controls a circuit operation of the wireless base station.
