Inventor: YOUNG LYDIA J
IPC: G03F7/20

Abstract: A reference and calibration grid (44a or 44b) of silicon is incorporated into a particle beam lithography system (10) and used to calibrate the system (10). The grid (44a or 44b) is formed in a silicon die (50) of much thicker structure and with square holes (64) and with a period to enable direct coordination with binary electronics. The grid (44a or 44b) is coated with a suitable material, preferably gold (72), to prevent charged particles or electrons from passing through the solid portions of the grid and the grid is preferably mounted on a grid holder (52) which can be aligned to the X-Y reference on the workpiece stage (32) and may be adjusted in tilt and in height (Z direction). The crystallography of silicon provides accuracies in orthogonality, corner radii, and edge roughness required for grids used as fiducials for particle beam lithography. In addition, as part of a thicker structure (silicon die 50), the grid (44a or 44b) can easily be handled and hence mounting and alignment procedures can be markedly simplified. The flatness of the grid (44a or 44b) is consistent over the whole surface.

Abstract: A torsional damper type flywheel device including drive side and driven side flywheels (10, 20), a first spring mechanism (30) connecting the drive side and driven side flywheels (10, 20), a second spring mechanism (40) which may include an air cushion spring, and a viscous damping mechanism (60, 80) arranged in series with the second spring mechanism (40). The series combination of the second spring mechanism (40) and the viscous damping mechanism (60, 80) is arranged parallel to the first spring mechanism (30) and connects the drive side and driven side flywheels (10, 20). This flywheel device continuously changes its vibrational behavior between two extreme characteristics due to the action of the viscous damping mechanism (60, 80). Due to the vibrational behavior change, no notable resonance occurs when the rotational speed passes through the resonance speed of the flywheel device. Also, since a continuously sliding friction mechanism is not used, its speed variation and torque variation absorbing effect is greatly improved at the standard range of engine speeds.

Abstract: A silicon-based laser mounting structure (10) is disclosed which provides improved interconnection between a semiconductor optical device, such as a laser (12), and an external high frequency modulation current source, by reducing the presence of parasitic inductive elements in the interconnecting network. The structure includes a stripline transmission path formed by depositing metal conductive strips on the top and bottom surfaces of a silicon substrate (16). The conductive strips are coupled at one end to the external modulation current source. A thin film resistor (14) is deposited between the second end of the top conductive strip and the semiconductor optical device. This thin film resistor (14) is utilized to provide impedance matching between the optical device and the stripline. That is, for a laser (12) with an impedance Z L , and a stripline designed to have an impedance Z S , the resistance R is chosen such that R+Z L =Z S . Utilizing silicon processing techniques, the thin film resistor may be placed adjacent to the laser (12), reducing the parasitics associated with their interconnection. A conductive via is formed through the substrate (16) to provide a top-­side bonding location for connecting the optical device to the bottom metal conductor. by providing the top-side site, the parasitic inductance associated with this interconnection is considerably reduced.

Abstract: Forward converters are specified in which MOSFETS, used instead of diodes, are controlled in synchronism with the clock switch (2) by the same control signal. In this case, the MOSFET (4) enabling the freewheeling circuit is driven inversely with respect to the clock switch (2). In the case of converters having potential isolation, an additional potential isolation (16) is provided in the control supply line to the MOSFETS arranged on the secondary side of the isolating transformer. The invention enables MOSFETS to be used for improving efficiency even in forward converters which have no isolating transformers. When isolating transformers are used, special control windings for the MOSFETS are dispensed with.

Abstract: The invention proposes a method for testing the brake on brake testing stands (13) for motor vehicles, suitable for all-wheel drive vehicles with a plurality of permanently coupled axles. In a preliminary test with braked wheels (14, 15), the sum of the driving powers of both driving motors (21, 24) for the sets (19, 23) of rollers is reduced to a minimum by the oppositely driven wheels of one axle (12), the power less dissipated in the propeller shaft (17) falling to zero. The driving powers at both motors (21, 24) determined during this process are retained at the left-hand and right-hand wheel (14, 15) during the subsequent brake measurements. Brake measurement can be carried out without readjustment and without a disturbing influence on the other, coupled axle standing on the ground. A suitable device (10) with total-power control unit (26) is indicated.
