Abstract: The system achieves high-resolution imaging with low-resolution two-dimensional imagers whose sensors are only a fraction of a selected pixel area. Sensors are stepped across an image with an optical or mechanical stepper to acquire an image at each sensor position. Thereby, resolution is defined by a step size which is comparable to the sensor size, rather than by pixel resolution. The system thus uses multiple image obtained from individual sensors, which have aa sensed area substantially less than the area of the pixels of a sensor array (34). Such rescanning is accomplished by movable mirrors or lenses (22,24,26,32) that are disposed between an illuminated specimen (20) and a sensor area (34).

Abstract: The signal to be measured is converted into digital form and read into a memory 13 using a trigger as the reference, and a signal of a length 1/5 that of the signal to be measured, in the vicinity of the trigger, is orthogonal-transformed (14). A frequency error  omega 1 of the transformed output I1,Q1 is estimated (15) and is used to correct the output II,QI (16). The corrected output I2,Q2 is subjected to processing by a receiving filter (17), and the filtered output I3,Q3 is synchronized with a PN code to obtain an ideal signal RI,RQ and a phase difference  tau 1 is calculated. The signal I3,Q3 and the ideal signal RI,RQ are used to obtain a frequency error omega 2 and a phase error  tau 2 of the signal I3,Q3. All signals to be measured, stored in the memory 13, are subjected to orthogonal transformation (23) so that the frequency error  omega 1+ omega 2 and the phase error  tau 1+ tau 2 are removed, and the transformed output I5,Q5 and the signal RI,RQ are used to calculate modulation parameters as is the case with the prior art. <IMAGE>

Abstract: Groups of magnets are respectively provided on the
joint surfaces of a vehicle-side connector and a power-supply-side
connector in such a way that the N and S poles of a
plurality of permanent magnets are alternately arranged in a
circle. When charging is carried out, the magnetic attraction
generated by placing the heteropolar magnets in both groups of
magnets opposite to one another is utilized for bringing the
vehicle-side connector and the power-supply-side connector into
engagement with each other. After the charging, the group of
magnets of the power-supply-side connector are turned by one
pitch to place the homopolar magnets in both groups of magnets
opposite to one another, whereby both connectors are easily
separated from each other because of the magnetic repulsive
force generated therebetween.

Abstract: To achieve both accuracy in correcting sensing
error caused by nonstandard factors of a pulse signal
generated by rotation of a rotor 2a-2d to be measured and
reduction in cost of an apparatus for doing the same, each
passage of rotor sensors 21 which rotate integrally with
vehicle tires 1a-1d are sensed to produce pulse signals. The
pulse signal periods Δt n  are sequentially integrated with
every pulse signal train consisting of multiple pulse
signals. When all of the pulse signal periods Δt n  of the
pulse signal train are integrated, the integrated value is
stored in memory. The memory always stores the integrated
values of the newest one rotation of the rotor 2a-2d to be
measured. The pulse signal periods Δt n  are averaged from the
sum of the integrated values. With such a construction, the
average of the pulse signal periods Δt n  can be obtained as a
learning reference value in the correction without storing
all of the pulse signal periods of one rotation, thereby
realizing both correction accuracy and cost reduction.

Abstract: The disclosure relates to an insulated wafer spacing mask (100) for supporting a workpiece (116) in a spaced apart relation to a workpiece support chuck (104). More specifically, the wafer spacing mask contains a plurality of support members (112) deposited upon an insulating material (113) located between the wafer spacing mask and the support surface of the chuck. The support members maintain a wafer, or other workpiece, in a spaced apart relation to the support surface of the chuck. The distance between the underside surface of the wafer and the chuck is defined by the thickness of the support members. This distance should be larger than the expected diameter of contaminant particles that may lie on the surface of the chuck. In this manner, the contaminant particles do not adhere to the underside of the wafer and current leakage through the wafer is minimized.

Abstract: A novel split threaded ring bearing member (42) for rolling cutter drill bits with
at least a portion of its threads (48) having a different pitch than its mating threads (40)
is disclosed. The pitch difference is designed so that the threaded ring can be seated or
otherwise located precisely with respect to the other bearing elements within the drill bit
to effectively control the axial displacement of the rolling cutter (18) on the bearing
spindle (16) within a given tolerance range. Upon assembly, the difference in thread
pitch causes the opposite, opposing mating thread flanks to engage, effectively applying
a tensile or compressive force to a portion of the threaded ring bearing member (42),
which gradually increases as the assembly is tightened. The result is an improved rolling
cutter drill bit with a threaded ring cutter bearing system with excellent resistance to
back-off which will not allow significant radial movement between the engaged threads,
even if some back-off of the threads occurs.
