A compressor system according to the present invention utilizes direct rotational input from a permanent magnet motor to generate compressed air. The permanent magnet motor is mounted directly to an air screw compressor. The rotational input is provided by the permanent magnet motor to the air screw compressor without a gear train. The permanent magnet motor and associated variable speed drive controls the rotational speed of the permanent magnet motor and hence the screw compressor. Differing motors may selectively mount, and provide rotational input to, the air screw compressor.

In order to effect a seal; a porous material which comprises one side of two opposing surfaces is used to restrict and evenly distribute externally pressurized gas, liquid, steam, etc. between the two surfaces, exerting a force which is opposite the forces from pressure differences or springs trying to close the two faces together and so may create a non contact seal that is more stable and reliable than hydrodynamic seals currently in use.

In optical module 10, light emitted from laser diode (hereinafter referred to as “LD”) 42 is collimated into parallel light beam by ball lens 44 and then travels through ball lens 26 to be focused on core 104 of optical fiber 100. Since the light passing between ball lenses 44 and 26 is the parallel light beam as described above, allowance is enlarged for axial misalignment between the optical axes of ball lens 44 and ball lens 26. This enables the light from LD 42 to be focused on core 102 of optical fiber 100 even if there occurs axial misalignment between the optical axes of optical fiber 100 and LD 42 due to a factor resulting from fitting of ferrule 102 into sleeve 14 or the like. Accordingly, there is no need for alignment in a work of mounting optoelectronic device 28, i.e., LD 42 in housing 12.

A retrievable tree cap for use on a subsea tree having a concentric bore. The tree cap may be installed and retrieved using a remotely operated vehicle. Hydraulic pressure may be used to lock the tree cap onto the subsea tree and to set the tree cap seals. The tree cap is locked onto the subsea tree before setting the seals within the concentric bore. The tree cap includes a locking means that may engage a profile within the subsea tree regardless of the radial orientation of the tree cap. The tree cap may be used to hydraulically isolate an annulus bore from the production bore of the subsea tree. The tree cap may provide for the injection of a corrosion inhibitor within a cavity of the tree cap and may also provide for the removal of water trapped between the tree cap and the subsea tree.

The present invention is a magnetic head having a helical induction coil and includes hard disk drive devices that utilize the magnetic head. The helical coil is fabricated around a magnetic pole yoke in a series of process steps that include a reactive ion etch (RIE) process step which is utilized to simultaneously form vertical interconnect vias and upper helical coil member trenches. Thereafter, in a single fabrication step, such as by electroplating, the vertical interconnect lines and the upper helical coil traces are created in a single fabrication step, such that they are integrally formed. The vertical interconnect lines provide an electrical connection between outer ends of previously formed lower helical coil traces and outer ends of the integrally formed upper helical coil traces, such that a helical coil is fabricated. In the preferred embodiment, the helical coil is composed of copper.

The invention relates to an apparatus and method for orienting an optical waveguide in relation to an optical unit arranged in or on an optical module. The optical module has a reference geometry which defines a first axis of symmetry. An offset between the optical axis of the optical unit and the axis of symmetry of the reference geometry is determined. A coupling element such as a sleeve is provided that serves to receive an optical waveguide that is to be oriented in relation to the optical unit. The sleeve has a hole defined by an internal contour thereof that defines a second axis of symmetry. The coupling element is arranged in relation to the optical module in such a way that the second axis of symmetry coincides with the optical axis of the optical unit.

The embodiment of the invention provides a prefabricated component producing system and relates to the technical field of prefabricated component production. The prefabricated component producing system comprises a transit trolley, a mold platen and multiple modules. The multiple modules are correspondingly arranged in multiple areas. The different modules are used for different treatment steps during prefabricated component production. The mold platen is used for driving a prefabricated component to transfer among the different modules, so that the component undergoes corresponding treatmentat the modules. The transit trolley is used for driving the mold platen to transfer among the different areas, so that the mold platen can achieve transfer among the different modules. In this way, compared with an existing prefabricated component producing system adopting the manner that rolling wheels are arranged on the ground to drive the mold platen to transfer, by the adoption of the transittrolley, the prefabricated component producing system can omit the processes of aligning the multiple rolling wheels, adjusting height of the rolling wheels and the like, so that the installation difficulty during arrangement of the prefabricated component producing system can be greatly lowered, and then the workload is lowered.
