An inkjet printer head includes a substrate having a manifold and an ink channel to supply ink, a nozzle plate formed on the substrate, a chamber formed between the substrate and the nozzle plate and extending toward the substrate and the nozzle plate, an electrode formed at an interface between the substrate and the nozzle plate and around the chamber, and a heater having both ends extending in contact with the electrode to be suspended on the chamber in direct contact with the ink and to generate bubbles from both surfaces thereof. The inkjet printer head is capable of improving manufacturing process efficiency by omitting a process of separately forming a heater passivation layer, operating the heater at low electric power by omitting the heater passivation layer, improving integrity of a nozzle by lowering a working voltage, and improving reliability in manufacturing processes by locating the suspended heater to be in parallel with the substrate and the electrode.

A method of manufacturing an ink-jet printhead, including forming an insulation film on a substrate, depositing a metal layer onto said insulation film and patterning said metal layer to form a heater, forming an electrical wire on said substrate, etching said substrate at a predetermined depth from a top surface of said substrate in a direction perpendicular to a major surface of said heater to form a narrow passage, depositing an ink chamber barrier layer on said top surface of said substrate and patterning said ink chamber barrier layer to form an ink chamber, stacking a nozzle plate having a nozzle on said ink chamber barrier layer and disposed on an upper portion of said ink chamber barrier layer, and applying predetermined pressure and temperature onto said nozzle plate to bond said nozzle plate and said substrate, and etching said substrate from a bottom surface thereof to form a wide passage communicating with said narrow passage.

An electric plug includes a plug housing, at least two incorporated plug-in contacts that are to be inserted into corresponding jacks of an outlet, and a cable feeder. A manually actuated ejection mechanism encompassing a push-out device is disposed in the plug housing. The push-out device cooperates with a spring in such a way that the spring is biased in the plugged-in state of the plug in order to allow the plug to be automatically removed from the outlet by means of the push-out device when the ejection mechanism is actuated. In order to actuate the ejection mechanism, the same is automatically triggered by pulling on the cable, the tensile force being effective on a strain relief device for the cable, which is located in the plug housing and cooperates with triggering device for actuating the spring-biased push-out device.

A washer nozzle includes a heat emitting unit for smoothly washing a glass in a winter season is installed. The washer nozzle for a vehicle which, by realizing a new type of washer nozzle to which an integral structure of a heat conductor and a nozzle cover is applied through insert injection-molding of the heat conductor is applied and to which a structure where a heat emitter is firmly fastened to the housing by using a structure in the housing is applied, can improve a washer liquid ejecting performance through an increase in a heat transfer efficiency inside the nozzle and reduce the number of processes and a defect rate through fixing of the heat emitter at an optimum location, thereby improving quality.

A deposition of bubbles or foams to an inner wall of a liquid supplying member is prevented, thereby improving ejecting performance of the bubbles or foams. In the liquid supplying member which forms a flow path for supplying a liquid to a liquid discharging apparatus, the inner wall surface has a concave/convex shape in which a mountain portion and a valley portion are repeated at a predetermined spatial frequency. Assuming that an opening diameter of a filter provided for the liquid discharging apparatus is equal to R (μm), one period f (μm) of the spatial frequency lies within a range from R or more to √{square root over (2)}·R or less and a maximum height Ry (μm) of the mountain portion is equal to √{square root over (2)}·R/2 or more.

An ink-jet head having a passage unit including pressure chambers each having one end coupled to a nozzle and the other end to be coupled to an ink supply source. The pressure chambers are arranged along a plane to neighbor each other. The ink-jet head further includes actuator units attached to a surface of the passage unit for changing the volume of each pressure chamber. Each actuator unit includes pressure generation portions respectively corresponding to pressure chambers, and is formed to extend over the pressure chambers. The actuator units are arranged along the longitudinal direction of the passage unit so that each neighboring actuator units partially overlap each other in the lateral direction of the passage unit. Each actuator unit has a basic region where many pressure generation portions are formed in a matrix, and an additional region neighboring the basic region in the lateral direction of the passage unit. In the additional region, pressure generation portions are formed to correspond to a gap portion between the pressure generation portions in the basic region of the actuator unit and the pressure generation portions in the basic region of another actuator unit neighboring that actuator unit.

The invention relates to an ejector with adjustable structure parameters. The ejector comprises a working nozzle, a low-pressure air inlet chamber, a straight pipe section, a diffusion chamber and a low-pressure air inlet chamber inlet pipeline. The diffusion chamber is formed by nesting three stages of diffusion pipes, so that a structure of the diffusion chamber can be changed through adjustingrelative positions of the diffusion pipes. The straight pipe section is formed by a basic straight pipe section and two stages of detachable straight pipe sections, so that the length of the straightpipe section can be adjusted through disassembling or installing detachable parts. A low-pressure air inlet chamber wheel disc and a working nozzle wheel disc are connected with the low-pressure air inlet chamber and the working nozzle into a whole; and during assembling, a main body of the working nozzle stretches into the low-pressure air inlet chamber, and a distance between the low-pressure air inlet chamber wheel disc and the working nozzle wheel disc is changed through adjusting an adjustable bolt, so that an outlet position of the working nozzle is adjusted. According to the ejector with the adjustable structure parameters provided by the invention, the structure parameters of the ejector can be correspondingly adjusted according to the change of an operation condition, so that an ejecting performance of the ejector under varying duty operation situations such as natural gas extraction is improved.
