Abstract: An exposure apparatus comprises a projection optical system, which projects a pattern
formed on a mask on a photosensitive substrate, a mounting object table, which holds the
photosensitive substrate, a positioning stage, which positions the mounting object table along a
2-dimensional movement coordinate system, a stage coordinate measurement device, which
detects the position of the mounting object table in the 2-dimensional movement coordinate
system, a height measurement device, which detects the deviation in the optical axis direction of
the projection optical system from the surface of the photosensitive substrate to a specified
standard surface in a measurement point fixed with regard to the 2-dimensional movement
coordinate system, a levelling device, which adjusts the inclination of the mounting object table
with regard to the positioning stage, a computation device, which calculates the amount of
levelling necessary to match the surface of the photosensitive substrate with the standard surface,
a control device, which controls the levelling device based on the calculation results of the
computation device, and a memory device, which stores the optical axis direction displacement
amount of the mounting object table produced at a measurement point when the positioning stage
is moved along the 2-dimensional movement coordinate system corresponding to the position of
the mounting object table detected by the stage coordinate measurement device, wherein, the
computation device calculates the amount of the levelling necessary based on a value obtained by
subtracting the optical axis direction displacement amount of the mounting object table stored in
the memory device from the deviation detected by the height measurement device.

Abstract: The method for determination of one or more operating parameters of an externally programmable (Pr) heart pacemaker (PM) involves measuring non-electrical quantities relating to the patient using a telemetric device (Tel). A sensor (S) for data capture and a control and evaluation unit (1) determine the value of the non-electrical quantities. An input (Pr/i) to the programming unit (Pr) is linked to the output (l/O) of the control and evaluation unit (1) and causes the programming unit to automatically initiate a process for measurement and evaluation of the non-electrical quantities using the telemetric unit (Tel) and from the measured values to optimise the operating parameters of the pacemaker.

Abstract: Fine patterns of metal or insulator can be formed on printed circuit board using conventional lithographic steppers with inverted projection lenses. The inverted projection lenses act as enlargement lenses rather than reducing lenses and exhibit a large depth of focus sufficient to accommodate the deviations of PC board from planarity. The inverted lens reduces the size of the image needed at the mask, permitting multiple mask levels to be combined on a single glass. This reduces the cost of the mask set and permits the use of smaller glass masks having greater accuracy and dimensional stability than the convention mylar masks used for PC board. 
     By inverting the projection lenses on near-obsolete steppers, applicants were able to form metal patterns on PC board of finer dimension than heretofore reported. Inverting a 5X ZEISS lens on a GCA 6300A stepper, applicants were able to form vias of less than 25 µm diameter, pattern metal lines and spaces of less than 25 µm, and obtain overlay registration accuracy of less than 25 µm. The field size was larger than 1 in 2 , and the depth of focus was greater than 50 µm.

Abstract: A recording apparatus configured to receive analog
video and audio signals, digitize and compress the same, and
record the compressed audio and video signals on a digital
recording medium such as an optical disk. As the audio and video
signals are received and recorded, time segments of the audio
signals are analyzed for certain features such as whether the
time segment corresponds to instrumental music, vocal music or
conversational speech. A table of contents is then generated
corresponding to the feature analysis and digitally stored on the
storage medium. As a result, the recorded audio is characterized
over time, e.g., on a frame by frame basis. A high degree of
versatility is thereby provided in the playback process, such as
the ability to skip portions having certain audio types or to
quickly scroll to desired portions of the recorded audio
programs. Reproducing apparatuses enable the user to selectively
reproduce segments of the recorded audio and video.

Abstract: The separation of enantiomeric pairs of compounds by capillary
electrophoresis using highly sulfated α-, β-, and γ-Cyclodextrins as chiral
selectors is described herein. These charged cyclodextrins have a
higher degree of sulfation and narrower heterogeneity than previous
cyclodextrin derivatives. CE analyses using highly sulfated cyclodextrins
produce improved resolution of a wide variety of chiral drugs, particulaly
neutral compounds and amines. The highly sulfated α-, β-, and γ-cyclodextrins
produce separations which complement each other to
further expand the number of neutral and basic drugs that can be
resolved by capillary electrophorsis.
