Abstract: A liquid crystal display (LCD) panel including an active device array substrate, an opposite substrate and a liquid crystal layer is provided. The active device array substrate includes a substrate, a plurality of scan lines, a plurality of data lines, and a plurality of pixel units. The scan lines, the data lines and the pixel units are disposed on the substrate. Each of the pixel units is electrically connected to one of the scan lines and one of the data lines correspondingly and crosses over two sides of the corresponding scan line. The opposite substrate includes a plurality of alignment protrusions. The alignment protrusions are located over the scan lines. Besides, the liquid crystal layer is disposed between the opposite substrate and the active device array substrate. The above-mentioned liquid crystal display panel has higher aperture ratio.

Abstract: In the method, a reed (3) for a weaving machine is continuously driven from a drive means (2) and the kinetic energy of the reed is stored in order to reduce the drive energy. The apparatus comprises an energy storer (1) and a drive means (2) in order to move the reed (3) back and forth. The matched oscillatable system formed by the energy storer and the reed reduces the drive torque at the uniformly rotating drive means whereby a reduction of the power consumption results.

Abstract: An accelerator lever for quickly accelerating a projectile to a high velocity in a loom comprises a lever arm (1b) coupled to a rotating shaft (2) by a clamping device (1a). The clamping device includes at least two fasteners (4c) extending through holes in the lever arm and the clamping device and threadably coupled to elements (4a) on the opposite side of the lever arm. The fasteners and elements provide a positive locking connection to firmly connect the lever arm to the shaft.

Abstract: The mechanism for the acceleration of a projectile of a projectile loom has a torsion-bar launching mechanism (1) with a striker lever (3) which, at its end remote from the torsion bar (2), carries a striker piece (34) which, during launching, acts directly on an impact face (43) of the projectile (4). The projectile (4) for the loom has a casing formed of a hollow body and may be partially closed at the rear, as viewed in the direction of flight. The striker piece (34) can pivot on the striker lever (3) and has at least one striker face (33) which is aligned by an alignment member (5) so that at the instant just prior to triggering of the weft insertion the position of the striker face conforms to that of the impact face (43) of the projectile (4); that is, for example, the two are parallel. The transmitted impact energy is uniformly distributed over the impact face of the projectile (4), which advantageously reduces wear of the striker face ( 33) and impact face (43).

Abstract: The picking mechanism has a torsion rod whose zero position is adjustable by an adjusting lever and an adjusting drive. A rigid wedge-shaped intermediate member movable by the adjusting drive is disposed between a sliding surface of the adjusting lever and a stationary sliding surface. Movement of the intermediate member produces a pivoting movement of the adjusting lever to alter the zero position. The intermediate member transfers a force exerted by the adjusting lever on to the stationary sliding surface.

Abstract: The picking mechanism is provided with two torsion bars. One torsion bar is stressed in order to accelerate a gripper projectile of the loom. The second torsion bar, upon release of the first torsion bar, is temporarily connected to the first torsion bar so that energy can be stored by the second torsion bar via a double-arm lever. During a return motion of the acceleration lever to a picking position, the second torsion bar is relieved of tension by delivering the stored energy to the drive shaft of the picking mechanism via the double arm lever. The picking mechanism thus uses only little energy.

Abstract: A projectile accelerator has a coupling transmission articulated between a cam follower lever and a picking lever which has two end positions. The projectile accelerator also has an eccentric rocker on the drive shaft which cooperates with a tensioning lug on the accelerating shaft in order to carry out a return motion of the picking lever without need for a large angular movement of the cam follower lever. The picking lever is able to traverse large angles of movement while the cam following lever traverses reduced angles of movement.

Abstract: The low-inertia and high-strength accelerating lever comprises a hub part, arm and end part made of a thermoplastics reinforced by high-strength fibers. The lever is built up from a number of layers in the form a Prepregs or semifinisheds, which are placed one on another, the layers having different fiber orientations and extending substantially parallel to the movement plane. Longitudinal components of the fiber orientations predominate in the arm with a gradual transition to the hub part and end part; the hub part and end part having a substantially isotropic distribution of the fiber orientations.

Abstract: The torsion bar firing device is provided with a striking lever having an end piece at the distal end which acts directly on the abutment face of a projectile on firing. The striking face of the end piece of the striking lever and/or the abutment face of a projectile may be formed as inclined planes or as convex, concave, or concave-convex surfaces. The direct drive of the projectile by the striking lever reduces the masses to be accelerated and braked. This advantageously influences the energy consumption and the weaving efficiency of the projectile weaving loom. The end piece may be integral with the distal end of the striking lever or may be in the form of a rotatably mounted roller of a trapezium shaped element.

Abstract: A picking device for the picking motion of a loom uses a pull string for delivering the picking energy to a pivot arm which is capable of being tensioned by way of a cam drive. The pull string can in principle be any elongate structure, e.g. a pull string of steel or a rope of high tenacity aramide fibers. The cam drive includes a toggle lever which is extended by a first cam and urged somewhat beyond its dead center, and which is urged by a second cam back over the dead center to initiate picking. A decelerating string is connected to the pivot arm to decelerate the pivot arm at the end of the pick.

Abstract: A non-impact printer has a movable printhead carriage for traversing a print medium and has a bracket, also serving as a heat sink, pivotally connected to the printhead carriage. A non-impact printhead is secured to the bracket and positioned to contact the print medium. A spring is positioned between the bracket and the printhead carriage to move the bracket and consequently the attached printhead into contact with the print medium. A printhead adjusting eccentric, causing relative motion between the printhead carriage and the bracket, enables vertical positioning of the printhead with respect to the print medium.

Abstract: The projectile weaving machine is provided with a torsion bar arrangement wherein oil is delivered to a central part of the torsion bar during operation. The oil circuit includes an oil entry in or near the torsion bar mounting and an annular chamber which is defined by a casing part about the torsion bar. A cooler is also provided in the oil circuit for cooling of the oil and the hydraulic brake assembly for the torsion bar is incorporated in the oil circuit.

Abstract: A cam drive is used to control the picking movement of the picking lever. The cam drive includes a dam disc which has a recess (or projection) which causes the lever to accelerate at the beginning of a pick and thereafter imparts a prestress to the spring before the cam follower of the lever moves out of the cam disc recess. A dog clutch is used to permit movement of the cam disc relative to the uniformly rotating drive shaft.
