A fuel injector, including a valve insert and a plug extrusion coating, is described, the valve insert including a valve seat and a valve housing. The valve housing has an alignment device, which is equipped to align the valve insert in an injection molding die, and the plastic extrusion coating has a second alignment device which is equipped to align the fuel injector during assembly in an internal combustion engine.

According to one embodiment, a method for manufacturing an ink-jet print head includes bonding an actuator to a base plate. The actuator includes a plurality of pressure chambers provided in a fixed direction and a piezoelectric member forming a wall of each pressure chamber and configured to change capacity of the pressure chamber. The method further includes connecting a wire to the piezoelectric member, and bonding a nozzle plate so that the nozzle plate is laid over the base plate at a predetermined distance from the base plate. The nozzle plate includes a plurality of nozzles corresponding to the pressure chambers. The method further includes arranging the base plate in a recess in a support member. The support member includes a flat portion provided with an ink supply aperture and an ink discharge aperture to circulate and supply ink. The recess is formed in the flat portion.

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.

Systems, methods, and software for fabricating a printhead. In one embodiment, a system comprises at least one punch press configured to punch first nozzle holes in a first nozzle plate with a first punch, where each of the first nozzle holes includes a first converging section, and to punch second nozzle holes in a second nozzle plate with a second punch, where each of the second nozzle holes includes a second converging section. The system further comprises a bonding tool configured to bond the first nozzle plate to the second nozzle plate to form a nozzle plate stack, where the first nozzle holes and the second nozzle holes define nozzles of the printhead.

In an embodiment, a fluid flow structure includes a micro device embedded in a molding. A fluid feed hole is formed through the micro device, and a saw defined fluid channel is cut through the molding to fluidically couple the fluid feed hole with the channel.

Provided is a liquid ejecting head including a fixing plate which includes a first surface and a second surface on a side opposite to the first surface, a plurality of head units which are fixed to the second surface such that the head units can eject liquid to the first surface side of the fixing plate, and a case member which includes a wall portion that is formed to surround the head units and fixed to the fixing plate and which has a plurality of protrusion portions formed in a part of the wall portion, which is the portion facing the fixing plate.

A circuit package comprises a circuit device in a first epoxy mold compound and a second epoxy mold compound of different compositions.

A printhead is provided having an elongate support having a plurality of internal webs protruding from a base section to define a plurality of parallel fluid supply channels, a shim supported by the support and defining a plurality of rows of openings through which fluid from respective supply channels is supplied, and a plurality of elongate printhead modules supported serially on the shim. Each module defines a plurality of fluid supply passages through which fluid passes to fluid ejection nozzles from respective rows of the openings. Either end of each module defines complementary formations such that adjacent modules nest together.

An ink-jet recording head includes a plurality of recording element substrates each having an ejection pressure generating element configured to generate pressure for ejecting ink from an ink discharge port. The plurality of recording element substrates each include a first surface on which the corresponding ejection pressure generating element is disposed and a second surface, serving as an end surface intersecting with the first surface, being at least partially formed by etching.

An adhesively bonded frame section for an agricultural sprayer boom is provided. One agricultural sprayer boom section includes a first support member and a second support member disposed adjacent to the first support member. The boom section also includes a side plate adhesively bonded to a first lateral side of the first support member, and to a first lateral side of the second support member to couple the first support member to the second support member.
