Title: Method of making ceramic cores and other articles
IPC: B28B1/24
Filed: 1989-11-28
Abstract: A novel method of making a ceramic core for 
use in casting a metal component includes freezing a 
ceramic slurry comprising a ceramic powder filler, a 
freezable liquid and a gelling agent in a mold to 
form a frozen core shaped body. The frozen core 
shaped body is removed from the mold and thawed to 
room temperature. A high viscosity gel is provided 
in the core shaped body at room temperature that is 
strong enough to retain the core shape until the body 
can be fired to form a porous, sintered ceramic core. 
The gel present at room temperature may be formed as 
the ceramic slurry is cooled in the mold cavity to 
form the frozen article shaped body and/or as the 
frozen core shaped body is thawed to room 
temperature.

Title: Process and apparatus for continuous production of cobalt-modified magnetic iron oxide
IPC: C01G49/00
Filed: 1990-04-03
Abstract: The time required for the cobalt modification 
treatment of magnetic iron oxide, which is a long time 
according to the convention technique, can be shortened 
and this treatment can be conducted in continuous 
manner. A magnetic iron oxide powder is covered with 
cobalt by a preliminary cobalt treatment, and then a 
cobalt modification treatment is carried out under 
high-temperature and high-pressure conditions (100 to 
200°C and 1.2 to 15 kg/cm²), whereby the total treatment 
time can be shortened to 2 to 6 hours, although the total 
treatment time is 9 to 50 hours in the conventional 
process. Moreover, by carrying out the cobalt 
modification treatment under high-temperature and 
high-pressure conditions by using a flow-type reaction 
vessel, it becomes possible to carry out the treatment in 
a continuous manner, although the treatment must be 
conducted batchwise in the conventional process.

Title: Coextrusion apparatus and method using an elastic die for varying the outer profile of a tubular extrudate
IPC: B29C48/34
Filed: 1991-07-06
Abstract: Coextrusion apparatus for varying the outer 
profile of a generally tubular extrudate (19) formed by inner 
and outer streams of elastomeric material by varying the 
annular end opening of an elastic die ring (45) which varies the 
size of an outer extrusion orifice and consequently the 
flow of the outer stream of elastomeric material which is 
deposited on the outer surface of the tubular extrudate. 
A hydraulically moveable piston (57) is axially slideably 
mounted for engagement with the elastic die ring and has a 
wedge-shaped camming surface which moves along the outer 
surface of the elastic die ring to vary the size of the 
outer extrusion orifice and consequently the amount of 
elastomeric material extrudated therethrough. A linear 
motion detector (65-69) is connected to the piston to detect the 
amount of linear axial movement of the piston to provide 
control signals for controlling the movement of the piston. 
The orifice for the inner stream of elastomeric material is 
located slightly upstream of the orifice for the outer 
stream of elastomeric material and is generally fixed. A 
reinforcing guide (14) directs a plurality of fiber-type 
reinforcing elements (15) into the tubular extrudate generally 
at the merger of the inner and outer streams of elastomeric 
material. A method for varying the outer profile of the 
tubular extrudate is also presented.

Patent EP-0636963-A3 (EP)
Inventor: GUSKI RICHARD HENRY
IPC: H04L29/06
Filed: 1994-07-25
Abstract: A system for authenticating a user located at a
requesting node to a resource such as a host application
located at an authenticating node using one-time passwords
that change pseudorandomly with each request for
authentication. At the requesting node a non-time-dependent
value is generated from nonsecret information identifying
the user and the host application, using a secret encryption
key shared with the authenticating node. The non-time-dependent
value is combined with a time-dependent value to
generate a composite value that is encrypted to produce an
authentication parameter. The authentication parameter is
reversibly transformed into an alphanumeric character string
that is transmitted as a one-time password to the
authenticating node. At the authenticating node the
received password is transformed back into the corresponding
authentication parameter, which is decrypted to regenerate
the composite value. The non-time-dependent value is
replicated at the authenticating node using the same
nonsecret information and encryption key shared with the
requesting node. The locally generated non-time-dependent
value is combined with the regenerated composite value to
regenerate the time-dependent value. The user is
authenticated if the regenerated time-dependent value is
within a predetermined range of a time-dependent value that
is locally generated at the authenticating node. Passwords
found not to have a corresponding authentication parameter
are trivially rejected by the authenticating node to avoid
unnecessary processing steps. A encryption system for
transforming short blocks into encrypted blocks of the same
length is also disclosed.

Abstract: A method and apparatus includes a geometry transfer engine (GTE) 61 acting as a coordinate transforming means for converting three-dimensional image data of TMD format into two-dimensional image data by perspective view transformation, and a graphics processing unit (GPU) 62 acting as a drawing means for transferring the two-dimensional image data in a given transmission standard to draw an image on a two-dimensional display screen. A structure of the three-dimensional image data, excluding the information to be perspective view transformed, is arranged identical to that of the given transmission standard of the two-dimensional image data. Accordingly, in the GTE 61, the information to be perspective view transformed is discriminated from the other data of the three-dimensional image data wherein the structure is identical to that of the given transmission standard of the two-dimensional image data, subjected to the perspective view transformation, and is combined with the other data wherein the structure is identical to that of the given transmission standard for production of the two-dimensional image data. An original format file including data to be transformed is thereby easily converted into a file having a new format. <IMAGE>

Abstract: A light control substance having a negative input-output
characteristic is used to invert optical signals. The light
control substance is an absorbing substance and has a multi-level
energy structure such that ground state absorption
occurs between a ground level (E 1 ) and a level (E 3 ) higher
than the ground level (E 1 ) and excited state absorption
occurs between an excited level (E 2 ) and a level (E 4 ) higher
than the excited level (E 2 ). At a specific wavelength, a
variation Δ Iout in the intensity of output light and a
variation Δ Iin in the intensity of input light satisfy the
following equations:
 Δ Iout = [1-α 1 (1+α 2 γ)]Δ Iin 
 α 1 (1+α 2 γ) > 1 
where α 1  is an absorbance of the ground state absorption, α 2 
is an absorbance of the excited state absorption, and γ is
a ratio of electrons relaxing from the level (E 3 ) higher than
the ground level (E 1 ) to the exited level (E 2 ). As a result,
the value of Δ Iout/Δ Iin becomes negative.

Abstract: Fine pulse width modulation (PWM) adjustments in the output of a
laser printer (11) are accomplished by receiving values from a bit map (21-24)
and modifying the values in accordance with values in a lookup table (LUT 27).
The lookup table (27) is subdivided into a plurality of blocks, and a selection of
the blocks is made in accordance with external values (45, 47, 51-54). This
allows the output of a pulse width modulation circuit (29) to be adjusted to a
precision that is greater than that afforded by the bit size of the values from the
bit map (21-24). The use of plural blocks in the lookup table (27) permits
adjustments in the output of the pulse width modulation circuit (29) in
accordance with external factors such as relative humidity (45), sensitivity of an
optical photoreceptor (48), and developer life (51-54).
