Abstract: (D Semiconductor fabrication using optical projection apparatus is enhanced in an arrangement having means for producing exposures tailored to the patterns on the conventional photo-mask. A predetermined correction photo-mask capable of producing different exposure levels according to the original mask pattern is superimposed with the original mask on the semiconductor wafer by sequential double exposure using an additional mask change and alignment. The drawings show an original mask pattern and a correction mask pattern.A better arrangement provides two beams simultaneously illuminating the two masks; the two beams are recombined with a high quality beam splitter arrangement before reaching the imaging lens. The two masks only have to be aligned to each other once. Afterwards, the wafer is exposed regularly. Therefore, an uncorrected image has the lowest threshold for an isolated opening, medium threshold for equal lines and spaces, high threshold for an isolated opaque line. After the correction scheme, all thresholds are made equal.The correction mask is made of grainless dyes of different light transmission or of one semitransparent substance of different thickness, such as thin layers of iron oxide, chromium or silicon. Standard lithographic patterning techniques, such as substractive etching, lift off or plating are used to fabricate the correction mask.

Abstract: The present invention provides a device for lapping valve seats (16) of for example steam valves in a power generating station. The device includes means for providing torque to be applied to a crankshaft (20) which includes an eccentric shaft on (28) at least one of its extreme ends. Mounted on each eccentric shaft (28) by way of a loose fitting bearing (33) is a facing disc (23) which are interchangeable to allow different sizes and abrasive grades to be used. During operation the facing discs (23) are pressured towards their respective valve seats (16) being lapped by helical springs (74) held within counterbores (73) of each eccentric shaft (28) thus urging the discs (23) axially outwardly of the crankshaft (20). During rotation of the crankshaft (20) the discs (23) tend to orbit around the valve seat (16) being faced at a slow rate while moving substantially radially inwardly and outwardly at the rotational frequency of the crankshaft (20). The device therefore provides a relatively fast and accurate refacing operating to the valve seats (16) which may have been worn or scratched during use. Further the apparatus saves the valve having to be removed from its steam line and thus greatly reduces overall time involved in the operation.

Abstract: An air atomizing nozzle assembly for electrostatic spray guns is disclosed. The nozzle assembly includes a fluid tip through which liquid coating material is emitted, an air cap having openings through which pressurized air passes to atomize the liquid coating material emitted from the nozzle and having a pair of opposed air horns through which pressurized air passes to shape the atomized coating material into a flat fan spray pattern, and a retaining ring for securing the air cap to the gun barrel and fluid tip. An annular diffuser is located within an internal chamber in the nozzle assembly which receives the pressurized fan-shaping air from a passageway passing through the barrel of the gun, redirects it, and equalizes the flow of the fan-shaping air to the opposed air horns. The present invention is particularly useful in applications having low liquid coating material flow rates on the order of less than about 3 fluid ounces of material per minute.

Abstract: A gas laser is provided in which either or both of two "plug-in" modules, one of which comprises the plasma chamber and the other of which comprises the associated high voltage components and circuitry, can be quickly and easily replaced by relatively unskilled personnel without any need for optical realignment. This feature makes it possible to use sealed plasma chambers even in applications where lasers are operated only intermittently and the sealed plasma chambers have limited operating life. With the elimination of the gas handling system, it becomes possible to manufacture compact, and in some important cases, portable and light weight lasers with replaceable plasma chambers and high voltage circuits. The invention is addressed to lasers operating at low to medium power output. 
     In a preferred embodiment, each high voltage electrode of the plasma chamber includes a connector plate that extends through the envelope and removably engages a support plate of the module containing the high voltage pulse circuitry. These support plates are precisely positioned with respect to two resonator mirrors mounted permanently on a base structure, while the connector plates are precisely positioned with respect to the electrodes and windows of the plasma chamber. The positioning of the connector plates with respect to the electrodes, the windows and the optical axis is identical for each of the interchangeable plasma chambers. The module containing the high voltage circuitry is releasably positioned on the base by two or more locator pins that retain it in a precise predetermined spatial and angular position with respect to the two mirrors. The position of this module with respect to the mirrors is identical for each of the interchangeable modules. 
     The plasma chamber module thus "plugs in" to the high voltage module which in turn "plugs in" to the base structure. Either or both of the modules are readily exchanged with any other similar modules without optical realignment. I -

The device (62) comprises, in the preferred embodiment, a ring (63) which cooperates with elements (68, 52) on the hose (13) and on the body (10) to prevent rotation of the hose (13) about the hose axis relative to the body (10) which could otherwise cause the cord (17) to wrap around the hose (13) until the cord (17) disengaged from the body (10). The ring (63) also has a fork (66) which cooperates with a preferably spherical enlargement (67) on the cord (17) to prevent disengagement of the cord (17) because of longitudinal tension on the cord (17) caused by longitudinal expansion of the hose (13).

Abstract: Telecine apparatus preferably of the line array type has the line scan rate controlled in response to a tachometer sensing the instantaneous film speed to overcome problems caused by film speed variations. The output signal is compensated in inverse relation to the scan period to compensate for consequent variations in the integration timeforthe array. For very slow film speeds the actual scan rate is increased from the required scan rate by a factor of a power of two and unwanted scans (dummy scans) are ignored. For very fast film speeds the actual scan rate is decreased from the theoretically required scan rate by a factor m, likewise a power of two, and a full picture formed from lines from the lastest m/2 fields, or by repeating or interpolating lines in the latest field only. To find a shot change at low film speeds the output picture has two parts, the junction between them being defined by a particular line scan, and the two parts being derived from two adjacent film frames. When the film is stopped, one part of the picture is the normal interlaced output and another part formed from a line direct from the linear array to enable proper functioning of the array to be confirmed.
