Abstract: PURPOSE: A system for aligning a semiconductor wafer through weight measurement is provided to more precisely perform an initial alignment of the semiconductor wafer, by supplying the quantity of air controlled according to the weight change. CONSTITUTION: An auxiliary unit is coupled to a side of a main supporting unit(70) on a wafer stage(30) by a ball-type hinge, tilted to a side according to the weight of a semiconductor wafer loaded on the wafer stage. A wafer weight measuring unit(40) converts the pressure at which a contact protrusion part(32) extended from a side of the auxiliary unit contacts a pressure sensor, to a weight value. The wafer weight measuring unit compares a reference weight value of the semiconductor wafer before a pattern is formed with the converted weight value. The wafer weight measuring unit supplies the quantity of air controlled according to the comparison result to an auxiliary unit having a plurality of air supplying holes corresponding to a plurality of air supplying holes of the main supporting unit.

Title: Transfer case with four-wheel underdrive operating mode
Inventor: SHOWALTER DAN J
IPC: B60K17/34
Filed: 1999-11-11
Abstract: PURPOSE: Transfer cases is provided for four-wheel drive vehicles and more specifically, a transfer case having a center differential is provided which is configured to selectively provide a four-wheel under drive operating mode. CONSTITUTION: A transfer case for a four-wheel drive vehicle includes a center differential which provides a direct output in two-wheel drive and a slightly reduced speed output in four-wheel drive. In two-wheel drive, the outputs of the center differential are locked together by a clutch collar and drive torque is provided to the primary drive line only. In four-wheel drive, the clutch collar unlocks the differential and couples the output from a sun gear to a chain drive sprocket in the secondary drive line. The center differential is driven through the carrier and operates as an open differential. The ring(outer) gear drives the primary drive line and the sun(center) gear drives the secondary drive line through cooperating chain sprockets and a chain. The chain drive sprockets are of unequal size and effect a speed reduction between the drive and driven sprockets. This speed reduction is nominally the same as the speed reduction from the input to the primary output achieved through the center differential. Thus, in four-wheel drive mode, the drive(speed reduction) ratio through the drive lines is raised, improving the acceleration and pulling power of the vehicle. In two-wheel drive, more favorable fuel economy is provided with the lower drive ratio.

Abstract: PURPOSE: A clearance reduced structure makes possible to insert/withdraw an inner tube from an outer tube for telescopic operation and prevents a vibration and a noise by compensating always a clearance, thereby increasing a durability. CONSTITUTION: An opening(21) is formed by incising the outside of an outer tube(2b) and is coated with a plastic bush(3) suitable for the size of the opening. The clearance between an inner tube(2a) and the outer tube(2b) is compensated by binding the bush(3) with an elastic ring(4). Therefore, the clearance does not occur because the elastic ring(4) push in the condition that the inside of the bush(3) adheres to the surface of the inner tube(2a). Thus, a telescopic operation controlling the length of a steering column is stable and a noise and a vibration is prevented by preventing the occurrence of the clearance between the inner tube(2a) and outer tube(2b).

Abstract: PURPOSE: A PLL(Phase Locked Loop) synthesizer circuit is provided to forcibly change an output frequency of the PLL circuit by the frequency change circuit and to complete change of the frequencies of the PLL circuit and change of receiving stations by the radio receiver in a shorter time. CONSTITUTION: For frequency change, the VCO(6) is controlled through a sub-charge pump circuit(13) to make a determination as to whether or not a difference of dividing data between before and after the change is within a predetermined range. When it is determined that the difference is outside the predetermined range, the loop filter(5) is forcibly charged in a charge time which is determined proportional to the difference in the dividing data, to thereby control an oscillation frequency of the VCO(6). A large VCO oscillation frequency change can be swiftly realized. Also, while the frequency change circuit is controlling the oscillation frequency, a time constant of the loop filter in the PLL circuit is preferably set at a small value, so that frequency change by the frequency change circuit can be swiftly achieved.
