Abstract: Acetic anhydride is produced by reaction of methyl acetate (or dimethyl ether and acetic acid), carbon monoxide, and hydrogen in the presence of an alkyl halide and a heterogeneous, bifunctional catalyst that contains an insoluble polymer having pendant quaternized phosphine groups, some of which phosphine groups are ionically bonded to anionic Group 9 or 10 (post-1986 IUPAC-recommended nomenclature) metal complexes, the remainder of the phosphine groups being bonded to iodide. In contrast to prior art processes, no accelerator (promoter) is necessary to achieve the catalytic reaction and the products are easily separated from the catalyst by filtration.

Abstract: A liquid specimen collection device includes a main body provided with a
passage extending between opposite ends of the main body that defines a capillary
tube liquid specimen flow path. One end of the passage opens at a tip end of the
body member that is positionable adjacent a liquid specimen for introducing the
liquid specimen into the passage while the opposite end of the passage opens at a
body surface of the body which surrounds and extends outwardly from the
opposite end of the passage. A test paper soaked in reagent is secured to the main
body adjacent the opposite end of the passage. A liquid sample introduced into the
passage at the tip end of the body member flows by capillary action along the
passage to the opposite end of the passage where the specimen is then absorbed by
the test paper. The test paper is secured to the body member at a plurality of
spaced apart securement locations along a peripheral portion of the test paper with
gaps being located between adjacent securement locations through which air is
permitted to flow during liquid specimen flow along the liquid specimen flow
path. The test paper includes a centrally located protuberance and an annular
protuberance extending around the outer circumferential portion of the test paper.
The end surface of the tip end of the body member can be provided with a groove
extending between the outer peripheral surface of the tip end and the passage in
the body member.

Abstract: The system has a read head with an optically active part which is formed by a very thin magnetic layer (32) that turns the polarisation plane of the light as a function of its magnetic polarisation. The magnetic polarisation of the very thin magnetic layer is linked to the magnetic polarisation of the magnetic medium (20). The read head has an integral optical guide (50) which opens directly in front of the active part of the medium so the plane of incidence of the light rays on the medium is perpendicular to the direction of an air gap (34'). A photosensitive detector (70,72) is integrated into the head where is receives light modulated by the passing data recording.

Abstract: A linear stimulating ray source produces
stimulating rays and linearly irradiates them to a portion
of a stimulable phosphor sheet, on which a radiation image
has been stored. A photoelectric read-out system divides
light, which is emitted from the portion of a front surface
of the stimulable phosphor sheet exposed to the stimulating
rays and/or the portion of a back surface of the stimulable
phosphor sheet corresponding to the portion of the front
surface exposed to the stimulating rays, into picture
elements along a length direction of the portion exposed
to the stimulating rays, and photoelectrically reads out
the divided picture elements by arraying them in a two-dimensional
form. A scanning system moves the stimulable
phosphor sheet with respect to the linear stimulating ray
source and the photoelectric read-out system and in a
direction, which is approximately normal to the length
direction of the portion exposed to the stimulating rays.

Abstract: DC and AC DCT transform coefficients of an
INTRA coded block (310) are differentially encoded
by selecting predictor DC and AC coefficients from a
left-hand neighboring block (320) and a top
neighboring block (340). Each block (310, 320, 340)
is coded according to a frame mode, a reordered
field mode, and a non-reordered field mode. The AC
predictor block is selected according to the
respective coding modes of the blocks, and the block
in which a DC predictor resides. The top block
(340) is selected as an AC predictor when the top
block (340) and current block (310) are both
reordered field mode, or both frame mode and/or
non-reordered field mode, and the DC predictor
resides in the top block. Zeroed AC spatial
transform coefficients are used in place of the AC
spatial transform coefficients from the selected
block when the selected block is not INTRA coded, or
does not reside in the same Video Object Plane (VOP)
as the current block. DC coefficients may be
non-linearly quantized.

converted to audio data by the text/audio converter (24) and
output from a speaker (18). Graphic data is converted into an

Abstract: We are familiar with etching printed circuit
boards chemically by providing a copper board with a mask
and etching copper away chemically at those points where
the mask is not present. This is disadvantageous, e.g.
from environmental standpoints, because the chemical
liquid is increasingly enriched with copper, and, when
the liquid has been used, it can no longer be employed
and is also difficult to dispose of. 
     The invention is based on the object of providing
a method of either applying or removing conductive
material electrically. 
     The inventive method of removing electrically
conductive material from a printed circuit board having
an etching mask, which covers the conductor structure,
arranged on it is characterized by the fact that the
following steps are carried out:
   a) the printed circuit board, together with an electrode,
is placed in an electrolytic liquid,   b) voltages of different potential are applied to the
printed circuit board and the electrode, and   c) electrically conductive material is removed from the
printed circuit board.

Abstract: The invention provides a motion data
preparation system which can acquire stable motion
data by detecting color markers without being
affected by the surrounding brightness, and which is
enabled to execute high-speed, accurate processing by
reducing the amount of information on color image
data. Color representations of about 16770 thousands
of colors for a 24-bit input image are integrated and
divided for each color camera, and outputted as 256
kinds of color group signals by look-up table memory
circuits 125, 126. Thus, the amount of information is
consolidated to about 1/60000, allowing a simple,
fast calculation to be realized. Further, the color
representation is separated into luminance (Y) and
chroma, for example, red color difference (R-Y) and
blue color difference (B-Y), and the chromatic
component is corrected by luminance. As a result,
errors due to effects of variations in illumination
conditions and the like can be reduced.

Abstract: A RAKE receiver includes an arithmetic circuit (9)
for weighting coefficients. The arithmetic circuit (9)
obtains the signal power for each path from the
reception amplitude on the path which is detected by a
transmission path characteristics detector (7a), and
also obtains the interference powers from the reception
amplitudes on two other paths which are respectively
detected by transmission path characteristics detectors
(7b, 7c). The arithmetic circuit (9) then calculates
the weighting coefficients (w1, w2, w3) on the basis of
the these signal powers and interference powers. The
weighting coefficients (w1, w2, w3) are respectively
supplied to weighting multipliers (6a, 6b, 6c), thereby
weighting the reception signals from the respective
paths. A symbol synthesizer (8) performs symbol
synthesis of the resultant signals.

Abstract: Paper jams and damage to a printing medium resulting from movement of a print head carriage
are prevented in a printing apparatus in which a print head unit (11) moves orthogonally to the
direction in which the printing medium (P) is transported through a transportation path past the
printing unit (10) for printing. A pair of transportation rollers (15a, 5b) is supported on opposite
sides of the transportation path in a manner enabling the transportation rollers to close and
open. The transportation rollers are closed to hold and transport the printing medium (P) in the
transportation path to the printing unit (10). A drive means is controlled to open and close the
transportation rollers according to a control command. When a non-print control command
involving print head movement is received, the drive means is controlled to close the transportation
rollers.
