Abstract: A rotary device has a first rotor having a recess and a second rotor counter-rotatable to the first rotor and having a radial lobe. A housing in which the rotors are enclosed has a first arcuate recess, an edge of the recess of the first rotor forming a sliding seal with the first arcuate recess during a portion of the rotation of the first rotor. The housing has a second arcuate recess, the lobe of the second rotor forming a sliding seal with the second arcuate recess during a portion of the rotation of the first rotor. Thus, for a portion of the rotation of the rotors, there is defined between the first and second rotors and the arcuate recesses of the housing a transient chamber of volume which progressively decreases on rotation of the rotors. The maximum volume of the transient chamber can be varied.

Abstract: A method and apparatus for writing clock data to a storage medium, such as a disk, is disclosed. The storage medium has tracks on which data are stored. Clock data is written to a present track on the storage medium. The written clock data is read from said present track. Clock data for a subsequent track on the storage medium is generated from the clock data read from said present track. The phase of the generated clock data for the subsequent track is compared with a reference timing signal and the phase of the generated clock data for the subsequent track is adjusted in accordance with said comparison. Said phase adjusted clock data for the subsequent track is written to said subsequent track. Phase errors can be significantly reduced and, for practical purposes, substantially eliminated. It is not necessary to provide a dedicated clock read/write head.

Abstract: After a CrSiN film and a TiW film are formed on a substrate through an intermediate insulating layer, a mask pattern is formed on the TiW film. Then a two-step dry etching treatment is performed to etch the TiW film and the CrSiN film into a specific shape. Specifically, first the TiW film is selectively etched under conditions including a large content of fluorine radicals. Then the CrSiN film is selectively etched under conditions including a large content of oxygen radicals. Accordingly, a thin film resistor can be formed with high accuracy with respect to the mask pattern.

Abstract: This process treats copper concentrates, either in the form of a primary sulfide, such as chalcopyrite, or a secondary sulfide, such as chalcocite and covellite, to obtain high purity copper metal having not less than 99.99% purity. In the case of a primary sulfide, the copper concentrate is subjected to leaching and is transformed into cement or a precipitated sulfide. In the case of the secondary sulfide, the copper concentrates are subjected to leaching with ferric fluoborate and fluoboric acid. Subsequent to leaching, the solution is subjected to copper electrowinning in a diaphragm cell to deposit copper on the cathode of the diaphragm cell.

Abstract: The present invention relates to a method for making a vehicle frame member having a shock absorbing mounting portion constructed and arranged to be mounted to a structural component within a motor vehicle. The method comprises hydroforming a tubular blank within a hydroforming die by supplying pressurized fluid to the hollow interior of the blank. A drawfornming member is moved inwardly with respect to the cavity of the hydroforming die while the fluid is pressurized so that the drawforming member deforms a portion of the tubular wall inwardly to form a recessed portion having an annular side wall portion and a bottom wall portion. The formed tubular blank is then removed from the hydroforming die and a mounting structure is disposed inside the recessed portion and the blank and mounting structure are then disposed within an injection molding die. Molten shock absorbing material is injected into the recessed portion so that the molten material surrounds the mounting structure.
