An improved hydrostatic power transmission is disclosed including first, second and third fluid displacement units, of which the first and second fluid displacement units are constructed as variable-displacement and constant-displacement units, respectively, while the third fluid displacement unit may be constructed either as a variable-displacement or as a constant-displacement unit as the case may be. The transmission system features split-power characteristics in which the second fluid displa...

The present invention provides a preparation for injection containing a lipid A analog and a process for preparing the same. A preparation for injection prepared by dissolving a lipid A analog or a pharmacologically acceptable salt thereof in an alkaline aqueous solution, at an elevated temperature if necessary, and then adding a buffer thereto, and a process for preparing the same.

An exposure apparatus includes a projection optical system for projecting a pattern of a mask onto a plate to be exposed. A pupil filter has a first area arranged on a light axis of the projection optical system and a second area formed outside of the first area. The mask is one of an alternating phase shift mask and a chromeless phase shift mask, and the pattern of the mask satisfies (p/.lamda.)NA.gtoreq.0.65, where p is a half pitch of the pattern, .lamda. is a wavelength of light illuminating...

A safety relief valve structure for a railway car having an enclosed shell which is adapted to be placed under an internal fluid pressure, especially for unloading particulate lading. A pilot-operated safety valve on the car has a main valve inlet communicating directly with the interior of the car, and a separate pilot line provides fluid communication between the interior of the car and the safety relief valve for controlling the operation of the valve. A filter is positioned in the separate p...

A reference-height calculating unit calculates an original height of a distortion detecting mirror when a distortion detecting mirror and a reference mirror are set in parallel to each other. A height measuring unit measures mirror heights when the distortion detecting mirror is tilted in directions of an X axis and a Y axis. A contour-line calculating unit calculates a pair of contour lines based on the mirror heights. An intersection calculating unit calculates an intersection of the contour l...

A device for the optical measurement of an optical system, in particular an optical imaging system, is provided. The device includes at least one test optics component arranged on an object side or an image side of the optical system. An immersion fluid is adjacent to at least one of the test optics components. A container for use in this device, a microlithography projection exposure machine equipped with this device, and a method which can be carried out with the aid of this device are also pr...

A pair of wipe down rollers are carried on a respective pair of rotatable arms to which arms force can be applied through separate air actuated cylinders so as to provide that the wipe down roller which engages in wipe down contact with the trailing vertical edge of a carton being sealed with tape applies a higher magnitude of positive wipe down pressure to such trailing vertical edge, than is applied by the wipe down roller which engages the carton leading vertical edge.

A method of sterile capping a plurality of I.V. bottles with temporary sterile caps. A plurality of caps are provided in a single sterile package, which package is opened within the confines of a sterile working environment and the caps distributed face-up on a working surface. Packing caps are removed from I.V. bottles within the sterile environment and dilutant added to the bottles. The bottles are then sequentially inverted and press-fit into corresponding temporary caps to achieve a sterile ...

A method for purifying tungsten hexafluoride of high purity, capable of producing tungsten hexafluoride of higher purity than that of the related art, readily and at a low cost. A method for purifying tungsten hexafluoride of high purity, characterized in that tungsten hexafluoride containing molybdenum hexafluoride as an impurity, makes contact with a layer, in which a metal or an alloy is packed, containing at least one of molybdenum, tungsten, copper, nickel, iron, cobalt, zinc, titanium, alu...

Herein disclosed is a hydrostatic power transmission system of the split power path type having a constant fluid displacement unit as a pump unit driven by a driving member such as a transmission input shaft of a motor vehicle and a variable fluid displacement unit as a hydraulic motor unit driven by the pump unit by means of fluid power and connected to a driven member such as a transmission output shaft of the motor vehicle. The two fluid displacement units are interconnected by a fluid circui...
