Abstract: A dual band antenna (1) includes a printed wiring board (PWB) (20). The PWB has an antenna trace (10) and a grounding plate (30) respectively disposed on opposite surfaces (20a, 20b) of the PWB. The antenna trace includes a radiating arm (100) and a matching means (13). The radiating arm includes a meandering segment (12) and a linking segment (11). The linking segment links two points of the meandering segment, thereby forming a closed loop. Because of the closed loop, the radiating arm has two transmission paths, one longer path, which does not include the linking segment, and one shorter path, which does include the linking segment. The dual band antenna, therefore, is capable of operating at two different frequency bands because of the two paths of the radiating arm.

The receptacle has a second housing (50), a plurality of contacts (60) received in the second housing, and a second shield (70) enclosing the second housing. The second housing defines a bottom surface (521) abutting against an inner surface of a bottom plate (72) of the second shield, and a top surface (520) spaced from a top plate (71) of the second shield.

The locking hands are slidably received in the locking groove. The holding member is thereby rotatably engaged with the fixing member.

Abstract: There is provided an apparatus which can make a correction such that paper will not be fed in a tilted state without a need for any special mechanism. A moving mechanism C1 is driven to move a printing head 41 toward a platen and to urge the printing head against paper, and gap adjusting means C2 is driven using said position as a reference to space the printing head from the platen a predetermined amount, thereby adjusting a gap between the printing head and the platen. The direction and amount of a tilt of the paper are detected based on signals output by paper detecting sensors E when the paper is fed. When said amount of the tilt exceeds a predetermined range, head driving means A and the moving mechanism C1 are driven to sandwich an edge of the paper in the direction of the width thereof between the printing head and the platen, and the sandwiched state is adjusted by the gap adjusting means C2.

Abstract: Variation in position of test marks formed of overlapping exposed features imaged by an imaging structure such as that of a lithography tool are characterized at high speed and with extremely high accuracy by imaging test marks formed in resist or on a target or wafer by a lithographic process, collecting irradiance distribution data and fitting a mathematical function to respective portions or regions of output data corresponding to a test mark of a test mark pattern such as respective maxima or minima regions or other regions of the irradiance distribution data to determine actual location and shift of position of respective patterns of test marks. Metrology fields are formed of patterns of test marks on test wafers or production wafers preferably including a critical dimension exposed at different focus distances and/or illumination conditions to capture position/aberration data for the imaging structure.

Abstract: The disclosure is for a film coating which yields increased life for optical media molds and the method and apparatus for making such a film. The film is a carbon nitride layer of 0.5 to 5.0 microns thickness with 2% to 45% nitrogen coated on an underlayer. One method of making the carbon nitride film is by the use of a pulsed carbon arc to generate a carbon plasma while injecting nitrogen into the vacuum chamber in which the arc is created. Another method is to generate a radio frequency plasma in a vacuum chamber into which acetylene and nitrogen gas are injected. The carbon nitride is formed by the combination of nitrogen with the carbon from the acetylene.

Abstract: To prevent temporary reduction of battery voltage when driving a shutter, an exposure control drive apparatus is provided with a boosting circuit for boosting a voltage of the battery and outputting a boosted voltage. A capacitor is charged by the boosted voltage for driving an actuator of an exposure control mechanism. A detecting circuit detects a current flowing in the boosting circuit and a control circuit controls operation of the boosting circuit in accordance with a magnitude of the detected value so that the boosting circuit is prevented from boosting the battery voltage when the detected current exceeds a predetermined level and is permitted to boost the battery voltage when the detected current is below the predetermined level. In this manner, the current flowing from the battery is prevented from exceeding a maximum level.

Abstract: Methods for using critical dimension test marks (test marks) for the rapid determination of the best focus position of lithographic processing equipment and critical dimension measurement analysis across a wafer's surface are described. In a first embodiment, a plurality of test mark arrays are distributed across the surface of a wafer, a different plurality being created at a plurality of focus positions. Measurement of the length or area of the resultant test marks allows for the determination of the best focus position of the processing equipment. Critical dimension measurements at multiple points on a wafer with test marks allow for the determination of process accuracy and repeatability and further allows for the real-time detection of process degradation. Using test marks which require only a relatively simple optical scanner and sensor to measure their length or area, it is possible to measure hundreds of measurement values across a wafer in thirty minutes.

Abstract: The present invention is intended to provide an economical printer which is simple in structure and uses a common tray but is capable of adapting itself to various recording media of different shapes. Adapters in which recording media can be firmly held can be selectively mounted in the tray. An adapter 24 has an oval opening 24a in which a recording medium 30 can be placed. The contour of the adapter 24 can fit into a recessed portion 23a formed in the tray 23. The recording medium 30 is firmly held in the adapter 24. When the adapter 24 is mounted in the recessed portion 23a in the tray 23, a keyway 23b and a protrusion 24b engaging the keyway 23b prevent the adapter 24 from shifting out of position; the adapter is held in the tray 23. Prints can be made in accurate positions on the recording medium 30.

The method and apparatus are used in a time recorder. An impact printing apparatus is also disclosed with printing pin actuation timing correction dependent upon scanning speed or platen shape, striking duration timing dependent upon scanning rate, or printing pin actuation timing dependent upon stored shift amounts.
