Abstract: An aryl-substituted saccharide or glycoside or a mixture of a plurality of aryl-substituted saccharides or glycosides have at least good resistance to high temperatures and salt, and lower filtration loss. These aryl-substituted saccharide or glycoside are used in making a drilling fluid composition. The aryl-substituted saccharide or glycoside or the mixture of a plurality of aryl-substituted saccharides or glycosides each or in combination bears a substituent A and a substituent B, wherein the substituent A contains a unit —O—R6— in its structure and the substituent B contains a unit in its structure, and the substituents and the numbers are defined in the description.

Abstract: The processing of audio signals during playback is provided, so that audio signals that fall below a specified threshold loudness level are processed to avoid making unwanted background noise audible. N-channel audio is received from a playback volume controller/leveler (101). The level of the audio is compared with a threshold level. If the level is greater than the threshold level, the audio is processed with a first amount of gain in accordance with a first dynamic range control (DRC) compression curve that is tuned for professionally produced audio. If the level is less than or equal to the threshold level, the audio is processed with a second amount of gain in accordance with a second DRC compression curve that is designed to avoid boosting unwanted background noise. After applying the gain to the audio, the audio is sent to a downstream device.

Abstract: The invention discloses a manufacturing process of a display screen cover, and a display screen. The manufacturing process includes the following steps: S1, providing a lamp panel provided with LED lamp beads; S2, arranging a glue barrier; S3, filling the hollow region of the glue barrier with glue I, and covering the LED lamp beads with the glue I; S4, providing a press plate; S5, curing the glue I; and S6, removing the press plate and the glue barrier. The cover does not need to be additionally assembled on the lamp panel, so that the lamp beads are protected against damage from the cover, and the yield of display screens is increased; and gaps between the lamp beads are completely filled with the cover, so that the lamp beads are fully protected.

Abstract: A flexible-die forming apparatus includes a piston, a coil, an upper die, a magnetorheological elastomer, and a lower die having a cavity formed thereon. The upper die is arranged to be overlappedly rested on top of the lower die. The piston is movably received in the receiving cavity of the upper die. The magnetorheological elastomer is mounted at a lower portion of the piston, and is received in the receiving cavity of the upper die. The coil is provided and wounded on an exterior surface of the upper die and the lower die.
