Paper webs having a watermark pattern

A process for producing paper webs having a pattern formed into the web is disclosed. The pattern is formed during formation of the web and is made by varying the basis weight of the web. The paper web is produced by depositing an aqueous suspension of fibers between two forming surfaces. One or both of the forming surfaces include lower permeability areas that create lower basis weight areas in the web. The lower permeability areas are contained in the forming surface according to a particular pattern. For instance, the lower permeability areas can be formed into a drainage roll sleeve contained on a drainage roll which contacts a forming surface. The drainage roll can be a forming roll or a breast roll.

Hold type image display system

InactiveUS20080238897A1Reduce move image blurLuminance be lowerTelevision system detailsCathode-ray tube indicatorsGate driverLiquid-crystal display
The present invention aims to prevent display luminance difference and burning with a line at which the polarity inversion switches when the order of inversion of black and video changes in the middle of the screen by a frame polarity inversion drive in a liquid crystal display device for performing black insertion drive. An enable signal (VOE) to each gate driver 5A to 5N is independently controlled, a start pulse (VSP) input to write a black signal is performed at an arbitrary timing within one frame period with respect to the gate driver 5A to insert a black image within one frame period, a write polarity of the video signal is inverted in frame cycle with the video display start pulse as a base point, and a write polarity of the black image signal is inverted in frame cycle with the black display start pulse as a base point.

Chemical analyzer and cartridge for chemical analyzer

A chemical analyzer has a rotatable holding disk, test cartridges disposed thereon, and a detector. The test cartridge includes a base plate having vessels and flow channels. The base plate is covered with a cover for covering the vessels and flow channels. The holding disk is rotated to generate centrifugal force, causing a fluid to be moved from one vessel at the inner peripheral side with respect to a rotation axis of the holding disk to another vessel at the outer peripheral side with respect to the rotation axis via the flow channel. In the test cartridge, at least one reagent port is formed in the base plate, and a closed vessel containing a reagent is placed in the reagent port. The closed vessel is a microcapsule, a plastic closed vessel, or a screw-in closed vessel, for example.

Process for producing photoresist composition, filter, coater and photoresist composition

A technique to acquire a photoresist composition which can reduce occurrence of defects of a resist pattern after development is provided. Further, a technique to obtain a photoresist composition having excellent storage stability characteristics as a resist solution (storage stability); and a technique to obtain a photoresist composition which reduces the change of sensitivity and resist pattern size after treatment almost completely are provided. A photoresist composition containing a resin component (A), an acid-generating component (B) for generating an acid under exposure, and an organic solvent (C) is passed through a first filter 2a equipped with a first membrane having zeta potential of more than −20 mV but no more than 15 mV in distilled water of pH 7.0.

Rotation sensor and direct current motor

InactiveUS20110148258A1Accurate detectionPreventing torque variationDC commutatorStructural associationPhase leadVaristor
A direct current motor includes an armature coil having at least three phase coils, a commutator having multiple commutator segments connected to the armature coil, a pair of brushes in slidable contact with the commutator to supply power to the phase coils through the commutator, a rotation shaft, and a ring varistor coaxially fixed to the rotation shaft and having a ring-shaped varistor body and multiple electrodes that are circumferentially arranged on a surface of the varistor body. Each commutator segment is connected to a corresponding electrode of the ring varistor. The electrodes of the ring varistor are paired to form electrode pairs. Each electrode pair includes any two of the electrodes. A capacitance of one electrode pair is different from a capacitance of another electrode pair.

Mechanism to avoid rate variations due to gravitation in a sprung balance regulating organ, and timepiece provided with such a mechanism

ActiveUS20110026373A1Avoids rate variationReduce weightEscapementsFrequency stabilisation mechanismChronometryKinematic chain
The mechanism avoids the rate variations due to the effect of gravitation on a regulating organ of a timepiece whose regulating organ includes a sprung balance and an escape wheel mounted onto a platform. The platform includes a counterweight and is mounted so as to freely rotate about at least a first axis relative to a plate of the movement so that this platform will rotate about the first axis under the effect of terrestrial gravitation. This mechanism includes a wheelwork with a driving kinematical chain linking the escape wheel to a barrel system of the timepiece, and a corrective kinematical chain compensating the movements and speed of the platform relative to the plate, so that these movements of the platform will not perturb the chronometry of the timepiece.

Wireless transmission system, relay device, wireless sink device, and wireless source device

A wireless transmission system is provided that can minimize the control command transmission amount by operating a plurality of sink devices in conjunction with each other with respect to each group when performing a wireless AV transmission. The wireless transmission system includes: a bridge device (1) which wireless-transmits an AV content; and a plurality of wireless sink devices (5, 6) which reproduce the wireless-transmitted AV content. The bridge device (1) has a group identification table which stores a group identifier for identifying a group formed by the wireless sink device (5, 6). The bridge device (1) adds a group identifier extracted from the group identification table to a control command for controlling the sink devices (5, 6) and wireless-transmits the control command having the group identifier. The wireless sink devices (5, 6) receive a control command wireless-transmitted from the bridge device (1) if a corresponding group identifier is added to the control command.
