IPC: G11B7/24024
Filed: 1991-02-18
Abstract: A double-side optical disc formed by a pair of optical disc halves bonded together, and a process for producing the double-side optical disc. An adhesive is applied to the disc halves, which are then bonded together at an angle relative to each other in which the direction of the adhesive flow on one disc half will intersect the direction of the adhesive flow on the other disc half.

Patent EP-0669659-A3 (EP)
Inventor: SATOH KATSUMI
IPC: H01L29/74
Filed: 1995-02-20
Abstract: When an abrupt voltage noise is applied across an anode electrode (A) and
a cathode electrode (K), displacement currents (I 10  to I 30 ) which are responsive to
junction capacitances (C 10  to C 30 ) of respective unit thyristors (ST 1 , ST 2 , MT) are
generated. The displacement currents (I 10  to I 30 ) flow into a compensation electrode
(C) through paths in a P base layer (2) having resistances (R 10  to R 30 ), and further
flow to an external power source through the cathode electrode (K) which is short-circuited
with the compensation electrode (C). The paths of the three displacement
currents (I 10  to I 30 ) are separated from each other by resistances (R 12 , R 23 ).
Therefore, a forward bias voltage of a junction (D 10 ) caused by the displacement
current (I 10 ) is attenuated by the displacement current (I 20 ), while a forward bias
voltage of a junction (D 20 ) caused by the displacement current (I 20 ) is attenuated by
the displacement current (I 30 ). Thus, it is possible to improve a thyristor of a
multistage structure in dv/dt resistance, at no sacrifice of sensitivity.

Title: Method of molding large containers by the process of stretch blow molding
Inventor: KODA HIDEAKI
IPC: B29C49/46
Filed: 1995-09-25
Abstract: There is provided a method of molding a large container (100) including the steps of preparing a preform (2) from an injection-molded, thick-wall closed-end parison (2) by repeatedly and intermittently applying an air blow pressure to the parison (2) and releasing the air blow pressure therefrom, and stretch blow molding the preform to a thin-wall large container (10). The closed-end parison (2) is released from a mold immediately after a skin layer keeping a parison shape is formed on the surface of the closed-end parison (2) having a high inner temperature, and is then molded to a preform (10) with a preform mold heated to a predetermined temperature, while the surface temperature of the parison is increased by the inner temperature. The preform kept at a stretch blow molding temperature is stretch blow molded into a blow mold to produce a large container (100).

Filed: 1995-11-20
Abstract: An ink supply device includes an ink container (3; 20; 60; 90)
connected to an air communication port (31; 80) through a
porous member (33; 43; 52; 62; 92). The ink container (3; 20;
60; 90) is maintained at a negative pressure equivalent to the
capillary force of the ink penetrated into the porous member
(33; 43; 44; 52; 62; 92). Since the ink container is in
communication with the air through a wide area of the porous
member (33; 43; 52; 62; 92), the ink container (3; 20; 60; 90)
can be maintained at a constant negative pressure regardless of
the quantity of ink consumed by the recording head.

Abstract: There is disclosed an aqueous dispersion usable
as a standard solution for determining lipid levels, having
a dispersion form and a particle size which are similar to
those of serum lipids. A lipid-containing dispersion is
obtained by evaporating an organic solvent from a mixture
prepared by adding cholesterol, a phospholipid, a bile
acid or bile acid salt, and a neutral lipid and/or a
cholesterol ester in the organic solvent, swelling the
resultant thin-film like mixture with water or buffer
heated at a temperature higher than a phase transition
temperature of the lecithin, and then dispersing the
solution by a physical shear force. There can be easily
obtained a solution having a cholesterol concentration of
about less than 1,000 mg/dl, which is extremely stable and

IPC: H04N1/46
Filed: 1996-12-20
Abstract: A digital color printing method and system is described which
automatically detects when a neutral grey object is commanded to be
printed, and changes the composition of the neutral color depending on the
previous value of the neutral grey object and on the presence or absence
of non-black colorants in the background color at the position on the page
at which the neutral object is commanded to be printed. A single-color
neutral object which is commanded to be printed at a position in which
there is a previously rendered color background which contains non-black
colorants may automatically have its neutral color changed from a single-color
neutral to a process neutral containing at least one non-black
colorant such as cyan, magenta, or yellow, said process neutral chosen to
have equivalent visual density and neutrality as the previous single-color
neutral value. Conversely, a process neutral grey object which is
commanded to be printed at a position in which the background does not
contain non-black colorants may automatically have the neutral color
changed from process neutral to single-color neutral, said single-color
neutral chosen to have the equivalent visual density as the process
neutral. For many printing systems the resulting prints exhibit fewer
visual defects. Neutral objects printed on top of a color field are
printed as process neutral and thereby may exhibit a greater gloss and
show fewer problems caused by the misregistration of separations or other
printer defects, such as white fringes around the neutral objects.
Conversely, neutral objects not on a color background are printed as
single-color neutral objects and therefore do not exhibit objectionable
process neutral problems such as color fringing, excessive colorant, and
excessive gloss contrast with the background.

anhand einer den Fahrzeugvortrieb kennzeichnenden Größe -
beispielsweise des Fahrzeugausgangsmomentes, das auf der Basis
einer Raddrehzahl ermittelt wird. Aus der Fahrpedalstellung
werden Sollwerte für die Motorsteuerung und für die Überwachung
ermittelt. Die Erfassung der entsprechenden Istwerte basiert auf
unabhängigen Eingangsgrößen.
