A gas turbine engine including a gas exhaust duct assembly which comprises an annular shroud forming at least a section of an inner wall of a gas exhaust duct, a plurality of strut members radially projecting from the shroud, and a plurality of insert members. The strut members are disposed in a circumferentially, substantially equally spaced-apart relationship, and extend in a substantially axial direction. The insert members each define a circumferential section of an outer wall of the gas exhaust duct and are positioned in a space between adjacent strut members, and are secured to same. The gas exhaust duct is thereby defined between inner surfaces of the insert members and the outer surface of the shroud, and is circumferentially divided by the respective strut members, for directing exhaust gases rearwardly in an axial direction, meanwhile surrounding flow passages are defined by outer surfaces of the insert members and the strut members in combination, for directing surrounding air flows rearwardly in an axial, radial and inward direction.

A USB portable disk-pen includes a USB plug that is inserted to a computer at an upper pen shaft, and is joined as one body with a sheath. A printed circuit board is connected with one end of the sheath, penetrated into the sheath, and positioned along with the sheath in the upper pen shaft. The upper pen shaft is relative lighter in weight for not containing a refill, and is therefore steadier and less likely to wobble when being inserted to a computer, thereby preventing poor contact quality of the USB plug.

A throttle body fuel injection system and method that is arranged to easily replace four-barrel carburetors includes a throttle body assembly with four main bores, each with a throttle plate and an associated fuel injector. Each injector feeds fuel into a circular fuel distribution ring via a fuel injection conduit, which introduces pressurized fuel into the air stream. The fuel distribution rings and bores have profiles that avoid constrictions for to prevent low pressure zones according to the Venturi effect. Fuel is injected through downward-facing outlets at or near the bottom end of the rings. The fuel injection rings are two-piece, each formed of an insert pressed into an outer housing. The insert includes axial grooves intervaled about its exterior circumference of insert that are joined by a circumferential groove formed about the insert. The grooves are in fluid communication with a conduit that supplies fuel from a fuel injector.

A method for manufacturing a fluid ejection device, comprising the steps of: providing a first semiconductor body having a membrane layer and a piezoelectric actuator which extends over the membrane layer; forming a cavity underneath the membrane layer to form a suspended membrane; providing a second semiconductor body; making, in the second semiconductor body, an inlet through hole configured to form a supply channel of the fluid ejection device; providing a third semiconductor body; forming a recess in the third semiconductor body; forming an outlet channel through the third semiconductor body to form an ejection nozzle of the fluid ejection device; coupling the first semiconductor body with the third semiconductor body and the first semiconductor body with the second semiconductor body in such a way that the piezoelectric actuator is completely housed in the first recess, and the second recess forms an internal chamber of the fluid ejection device.

A tank unit includes two or more liquid accommodating containers disposed in a row. Each of the liquid accommodating containers includes a main body having a concave shape defining a side opening and a film that blocks the side opening. The main body and the film at least partially define a liquid accommodating chamber for accommodating a liquid. The main body includes a facing wall that faces the film across the liquid accommodating chamber and has a wall larger than the side opening. The liquid accommodating containers are disposed such that the film of at least one of the liquid accommodating containers is covered by the facing wall of an adjacent one of the liquid accommodating containers.

The present invention provides a light-shielding image-carrying substrate including a substrate and a light-shielding image formed on at least part of at least one face of the substrate, wherein the light-shielding image includes at least two layers, and at least one of the at least two layers is a light-absorbing layer containing shape-anisotropic fine metal particles, and at least one layer of the at least two layers is a reflected light-absorbing layer.

A method of manufacturing an ink jet head includes the following steps, wherein the ink jet head is provided with a plurality of pressure chambers arranged continuously, ink feed means for feeding ink into these pressure chambers, and ink ejecting means for ejecting ink from each pressure chamber via a nozzle, so as to feed and eject ink by a change in volume of each pressure chamber. First, a first metallic film is formed on both surfaces of at least one wall composing the pressure chamber perpendicular to an arranging direction of the plurality of pressure chambers, wherein the at least one wall is one wall of a piezoelectric element deformed when a voltage is impressed. Then, the first metallic film formed on one of the both surfaces of at lest one wall is removed to form an exposed surface of the wall of the piezoelectric element. Thereafter, a second metallic film is formed on the exposed surface, whereby metallic films, thicknesses of which are different from each other, are formed on the both surfaces of at least one wall of the piezoelectric element.

The invention is directed to provide a method for producing an ink jet recording head, which is free from the problems produced by an inexpensive system, and excellent in discharge stability. The present invention provides a method for producing an ink jet recording head equipped with an ink discharge port from which the ink is discharged, ink discharge port face on which the ink discharge port is set and discharge energy generating element which generates energy necessary to discharge the ink, and is finished water-repellent in such a way to make the ink discharge port face hydrophilic partly around the ink discharge port, comprising the following steps, a step which forms the photosensitive water-repellent processing layer in the ink discharge port face, a step which irradiates light onto the water-repellent forming region and hydrophilic forming region in the water-repellent processing layer, to cure the layer, a step which irradiates light selectively onto the hydrophilic forming region to reduce water repellency of the water-repellent processing layer and to impart hydrophilicity to the hydrophilic forming region, and a step which forms an opening, which constitutes part of the ink discharge port, in the water-repellent processing layer.
