  • Publication number: 20230416220
    Abstract: A process for refining glycolide includes a step of extracting impurities from a crude glycolide with solvent A, and then a step of recrystallizing with solvent B. Solvent A includes at least two solvents and the solvents are miscible each other. In the process, two types of polar solvents are used for the refining of crude glycolide. The process has a good extraction effect on acidic impurities such as glycolic acid oligomers. The solvents are easily fully removed during the solid-liquid separation and the drying process. Glycolide obtained using this process may have a low free acid content.

  • Patent number: 10964764
    Abstract: A display panel and a method of manufacturing thereof are provided. The pixel defining block is formed by one-time exposing the column spacer column and the bank with a halftone mask, thereby omitting the process of individually forming the bank, and manufacturing time and manufacturing cost are reduced. The organic functional layer disposed above the bank is not directly contacted with the first electrode due to the bank structure, and the bank causes the defined region to be disconnected from the first electrode, and no current flows through the defined region. Thus, the defined region does not emit light, and the pixel region emits uniform light. The material of the bank is an organic photoresist, so hydrogen and oxygen are not introduced into the bank, and therefore not affect the thin film transistor, and improves stability of the display panel.

  • Publication number: 20090167943
    Abstract: Techniques for synchronizing audio and video data being transferred from one device to another device are disclosed. According to one aspect of the present invention, a periodic signal is generated in a host device (e.g., a personal computer) and transferred to a thin device (e.g., a PC camera) via an interface (e.g., a USB). The periodic signal is used to adjust local clocks in the thin device to generate audio and video data. As a result, the audio and video data is synchronized. According to another aspect of the present invention, an error detection unit and a correction unit are provided to ensure that there is no error in the periodic signal being transferred from the host device. If an error is detected, a patch to the signal is generated.

  • Publication number: 20060265527
    Abstract: Techniques for increasing the efficiency in se of a data bus are disclosed. A bus system includes a bus for transferring data, and a device, being coupled to the bus for data transfer, including a functional module providing data required to be transferred over the bus and a first-in-first-out device (FIFO) coupled between the functional module and the bus. The FIFO is provided to store pending data from the functional module before the bus is granted to the functional portion in responding to a bus request (BUS_REQ) for transferring the data over the bus, wherein topside data in the FIFO always drives the bus so that the topside data is immediately transferred over the bus once the bus is granted to the device or the functional module.
