Abstract: An electro-optic material (2) has first (4) and second (6) regions formed therein. The optic axes of the first and second regions are antiparallel and define a domain inversion pattern. The difference in refractive index between the first and second regions is a function of an electric field applied thereto. The difference in refractive index enables spatial light phase modulators and refractive optical devices having electrical control to be formed.

Abstract: An automatic transmission includes a plurality of power transmitting gear trains making up a combination of forward power transmitting paths that can be selected one at a time, a plurality of frictional engaging elements for selecting one of the forward power transmitting paths at a time, and a one-way clutch for establishing a lowest-speed gear position among the forward power transmitting paths. When a gear shift is to be made from a neutral gear range to a forward gear range, one of the frictional engaging elements which is mechanically coupled to the one-way clutch is preliminarily engaged. When the gear shift can be made from the neutral gear range to the forward gear range, one of the frictional engaging elements for establishing the starting gear position starts being engaged, and thereafter those frictional engaging elements which are not necessary to establish the starting gear position are released. Because the frictional engaging element is mechanically coupled to the one-way clutch is preliminarily engaged, vibrations produced upon rotation of the one-way clutch are reliably suppressed when the gear shift is made from the neutral gear range to the forward gear range.

Abstract: A modified investment casting process is provided which allows cast articles having a smooth surface finish to be obtained while using casting patterns made of a photocurable liquid polymer by a stereolithography process, or by molded thermoplastic materials. Moreover, the process of the invention eliminates or minimizes the incidence of mold cracking due to expansion of the casting pattern. The process involves first preparing a casting pattern through a stereolithography process or through molding a thermoplastic material. Thereafter, a wax or wax like coating is applied to the casting pattern and an investment assembly is prepared. A mold is obtained from the investment assembly by first subjecting the investment assembly to a first temperature range sufficient to melt and extract the wax or wax like material, leaving behind the casting pattern. Thereafter, the investment assembly is subjected to an elevated temperature in a second temperature range that is sufficient to melt and extract the casting pattern.

Abstract: Provided are a coloring composition and a coloring
method for microorganisms, and a method for storing the
composition. Using the composition, the number of
microorganisms in samples can be measured rapidly and in a
simplified manner, and the degree of coloration of the
colored microorganisms varies little with the lapse of time.
The composition has good storage stability. Also provided
is a filter tool for entrapping bacteria, with which only
bacteria can be entrapped rapidly and in a simplified
manner from samples containing bacteria and animal cells or
vegetable cells. The filter tool is utilized in a kit and
a method for measuring the number of bacteria in samples.
Further provided are a kit and a method for measuring the
number of bacteria, which do not require any special
equipment and any expert technical knowledge. Using the
kit, the number of bacteria in samples can be measured
rapidly and in a simplified manner through one-stage
filtration. The coloring composition comprises a dye and a
surfactant, and is controlled to have a pH of from 4 to 6
or is used in a controlled pH range of from 4 to 6. The
composition comprising a dye and a surfactant is stably
stored in a pH condition ranging from 4 to 6; or the
composition comprising a dye is stored in a pH condition
ranging from 4 to 6, and a surfactant is added thereto 
before use. The filter tool comprises a first filter
having a pore size of from 30 to 70 µm and a second filter
having a pore size of from 0.45 to 4 µm. The kit comprises
the filter tool, of which the second filter is a
hydrophobic filter, a dye-containing liquid composition,
and a colorimetric means. To measure the number of
bacteria in samples, a bacteria-containing sample is
introduced into the filter tool in such a manner that the
sample is first brought into contact with the first filter,
whereby the bacteria are entrapped with the second filter,
and the number of bacteria in the sample is determined from
the degree of coloration of the second filter.
