Abstract: A thickness extensional piezoelectric resonator utilizes harmonics of a
thickness extensional vibration mode and has a significantly reduced size and
significantly increased capacitance while not being susceptible to the effects of the
stray capacitance of a circuit board upon which the resonator is mounted. The
resonator includes a piezoelectric strip, first and second excitation electrodes
located on one of two respective major surfaces of the piezoelectric strip, and
internal electrodes disposed inside the piezoelectric strip. The first and second
excitation electrodes are located on opposite sides of the piezoelectric strip. The
internal electrodes are located opposite to the first and second excitation electrodes
to thereby define a vibrating portion. Vibration-attenuating portions are located on
opposite sides of the vibrating portion only along the longitudinal direction of the
piezoelectric strip. No vibration-attenuating portions are located in the lateral
direction of the piezoelectric strip.

Abstract: A method and apparatus of producing gray level
images comprises controlling a gray level printhead such that
the printhead forms dots of variable dot sizes on a
recording medium at plural pixel locations, the pixel
locations being grouped into cells having cell gray levels,
wherein the dots of a cell are determined such that for each
increase in cell gray level, a dot at at least one of said pixels
in the cell forms a larger dot-size. Cell growth patterns for
full dot, partial dot and mixed dot are described. In another
embodiment, statistical information of dot regions from a
digitized image signal are collected and a dot type to render
that cell dot region in accordance with the statistical
information is provided for. In a further embodiment, a gray
level printer forms dots along lines in accordance with at
least a first template corresponding to increasing cell gray
levels until a first line structure is stable and the gray level
printer forms dots along lines in accordance with at least a
second template corresponding to further increasing cell gray
levels. In still another embodiment, pixels in each cell are
classified into one of at least two classes and an exposure
level for printing said pixels is modified according to the
classification. In another embodiment, scanned pixel values
are compared to a set of thresholding values that are defined
by a 4-quadrant tone reproduction analysis using a dot
template, selected bit depth and dot type structure. A gray
level halftoned representation of the image is generated
using the thresholding values. In another embodiment, the
intensity values of some pixels are modified by introducing
errors to intensity values of pixels at preferred locations such
that pixels along screen lines have a greater likelihood to be
printed with stable dots than pixels not at such preferred
locations. Errors, created by modifying the intensity values 
of pixels at such preferred locations, are diffused to pixels
neighboring the pixels at said preferred locations. In still
another embodiment, a region of an original image is
analyzed to determine if it contains either a text region or a
halftone region, and contour suppression is performed on
every pixel of said region. In accordance with another
embodiment, a region of an original image that contains
either a text region or a halftone region is printed by a gray
level printer with an output screen frequency higher in screen
frequency than the screen frequency of the original image. In
still another embodiment of the invention, a descreening
filter includes means for transforming the digitized image
into a frequency domain, means for reducing the strength of
a specific frequency content from the digitized image, and
means for transforming the digitized image back into the
spatial image domain and feedback means between the
spatial domain and the frequency domain to iteratively reduce
to a minimum the specific frequency in the digitized image.

Abstract: It is an object of the invention to provide an optical
signal receiving circuit, which secures a dynamic range of a
pre-amplifier used therein and can be simply designed without
paying special attention to a gain-phase characteristic of a
feed back circuit. A resistor is connected in series with a
photodiode, and a signal voltage proportional to an input
optical signal level is detected by a peak-detecting circuit,
an output voltage of which is supplied to a gate of a FET
connected in parallel with a fixed feed back resistor of a
current feed back amplifier. The feed back resistance is
controlled by internal conductance of the FET, which is changed
by the gate voltage.

Abstract: A flow control valve system precisely diagnoses the condition
of a flow control valve and reflects the diagnosis in linear
control, thereby achieving high reliability. An electronic
control unit (ECU) executes an abnormality diagnostic
operation regarding an exhaust gas recirculation (EGR) valve
when exhaust gas recirculation is being performed and the EGR
flow is in a steady condition. For an abnormality diagnostic,
the ECU first calculates an amount of control (amount of
negative pressure) needed for the EGR valve to start an
operation in a manner opposite to the manner of the previous
operation, and sets the control amount as a function of an
amount of hysteresis between the start of opening and the
start of closing of the EGR. If there is an increase in the
calculated amount of hysteresis, the ECU determines that the
EGR valve has an operation abnormality due to deterioration
of the valve or the like. In accordance with the degree or
extent of the abnormality, the ECU selectively performs an
operation, that is, corrects the amount of control or stops
the exhaust gas recirculation.

Abstract: This system and method error-diffuse image data to
generate printing decisions; scan and print stages are
preferably included. Multiple image-data rows (or at
least parts thereof) are held in longterm memory, usually
external to an integrated circuit that does the processing;
preferably data from plural rows at a time are received
from that memory. Error from earlier-processed
data is also held in longterm memory and fed to the circuit.
Longterm-memory access is shared with many other
functions; the invention keeps error diffusion from dominating
that access. Processing preferably proceeds generally
transverse (preferably skewed, ideally at 45°) to
data rows, with final error distribution into each pixel
when it is the "left pixel" (or when it is the "next pixel"
if it is at the top of a row group). For pixels at
the top of each run, the circuit retrieves error from, and
for pixels at the bottom the circuit deposits error into,
longterm memory; for intermediate pixels the circuit does
neither ― thus amortizing each data access over several
pixels. Preferably plural rows are preprocessed to impart
a skewed structure and also insert dummy pixels at corners
(to simplify repetitive processing) ― ideally with data
and dummy pixels together forming a parallelogram, the
dummy pixels being outboard at both sides of the data.
Data can be padded out internally, too, for colorimetric
improvement, if correspondingly finer printing resolution
is available. In one form of the invention two or more
( e. g. , four) current pixels are processed simultaneously.

Abstract: A pure steam-related apparatus, which is one of apparatus
in the group of pure steam generators generating pure steam from
purified water, pipelines for pure steam and sterilizers using
pure steam, is protected from discoloration, so-called
"fouling", to red or black caused by contact with the pure
steam. The apparatus is manufactured by using an austenitic
stainless steel sheet as the material, by taking the blanks from
the material which received no mechanical surface polishing, by
deforming and welding, without electrolytic polishing
customarily done, and by passivating the surface to contact pure
water to increase Cr-content in the passivation film to such
extent as 45 atomic % or higher, preferably 55 atomic % or
higher. Better results will be obtained by ensuring Cr/Fe
ratio in the passivation film at the level of 1.45 or higher,
preferably, 1.70 or higher.
