  • Patent number: 8578603
    Abstract: A compressing device, a drive shaft and a bearing device are assembled into a tubular member. All-around welding of a cover member to the tubular member is performed to form a casing in such a manner that welding is overlapped over a welding start point, at which the all-around welding is started, to form an overlapped portion in a welding bead generated by the all-around welding. In the all-around welding, heat input is externally applied to a diametrically opposite portion of the casing, which is diametrically opposite to the overlapped portion, so that the diametrically opposite portion is deformed symmetrically with respect to a welding distortion at the overlapped portion.

  • Publication number: 20130289503
    Abstract: The illustrative embodiments described herein are directed to apparatuses, systems, and methods for managing liquid flow associated with a tissue site that involves using reduced pressure to control fluid flow. In one instance, an apparatus includes a first valve and a second valve in fluid communication with a reduced-pressure source. The valves are movable between an open position and a closed position and are operable to change flow status (open to closed or vice versa) based on a presence of reduced pressure. At least one of the first valve or the second valve is in the closed position to obstruct a flow of a liquid while the other is in the open position. The apparatus also includes a reservoir fluidly coupled to the first valve and the second valve. Other systems, methods, and apparatuses are presented.

    Abstract: A compressor and a method of assembling the compressor are provided. The compressor includes: a shell; a motor arranged in the shell, the motor having a stator, a spacer mounted with a first bearing therein, a drive shaft supported by the first bearing and a rotor fixed onto the drive shaft; a low bearing support; a positioning member positioning the second bearing and being connected to the low bearing support; and a second bearing connected to the positioning member and/or the low bearing support and supporting the drive shaft. Furthermore, the positioning member may be removed from or maintained in the compressor after it is assembled. The present invention can avoid the adverse effects of the gravity of the rotor and the drive shaft and/or the magnetic force between the rotor and the stator on positioning the bearings and the drive shaft and can improve positioning accuracy and assembling efficiency.

    Abstract: A micro-dosing pump includes a pump chamber substrate, a flexible membrane, a fluid line, a valve disk, a magnetizable actuator disk, and a drive unit. The pump chamber substrate has a pump chamber. The flexible membrane is on a first side of the pump chamber substrate and covers the pump chamber in a fluid-tight manner. The fluid line is on a second side of the pump chamber substrate such that fluid can enter and leave the pump chamber. The valve disk, arranged inside the pump chamber, has a fluid through-opening and is configured to close the fluid line by rotating and to open it via the through-opening. The actuator disk is coupled to the valve disk such that rotating the actuator disk rotates the valve disk. The drive unit has a pump plunger configured to move the membrane for suction or ejection of fluid and to rotate the actuator disk.

  • Patent number: 8485795
    Abstract: A diesel pump having enhanced durability in a high pressure environment, capable of being produced at high productivity, and at low cost. The diesel pump is provided with a cylinder formed in a pump housing, a plunger reciprocatably provided in the cylinder, and a drive mechanism for driving the plunger. The cylinder is a separate part from the pump housing and is mounted in the pump housing. The cylinder consists of sulfur-less alloy steel, is a tubular part and may be press-fitted in the pump housing. The front end of an outlet joint reaches the cylinder, and a fuel discharge route directly connects to the outlet joint from the cylinder without passing through the pump housing.

  • Publication number: 20130167374
    Abstract: A process for producing a silicon-containing CMC article. The process entails depositing one or more coating layers on silicon carbide (SiC) fibers, drawing the coated SiC fibers through a slurry to produce slurry-coated fiber material, and then processing the slurry-coated SiC fiber material to form unidirectional prepreg tapes. The tapes are stacked and then fired to yield a porous preform. The porous preform is then further densified by infiltrating the porosity therein to yield a CMC article. Infiltration can be achieved by a series of polymer infiltration and pyrolysis (PIP) steps, by melt infiltration (MI) after filling the porosity in the preform with carbon or one or more refractory metal, by chemical vapor infiltration (CVI), or by a combination of these infiltration techniques.
