Title: Method for using ionic liquid heteropoly acid catalyst to synthesize polyol acetate ester
Inventor: Wu rong-zong
IPC: B01J31/02
Filed: 2011-10-27
Abstract: The invention relates to a method for using ionic liquid heteropoly acid catalyst to synthesize polyol acetate ester, characterized in that an organic nitrogen-containing compound is reacted with an alkyl sulfonic acid lactone to generate a white zwitterionic compound solid. The white zwitterionic compound solid is purified and dried which is reacted with a heteropoly acid (HPA) to obtain a transparent viscous waterproof acidic ionic liquid heteropoly acid (IL-HPA) catalyst. An ethyl esterification reaction of polyol and acetate is effectively performed to produce polyol acetate ester by using the transparent viscous waterproof acidic ionic liquid heteropoly acid catalyst; and a vacuum process is performed to recycle acetate and a dewatering process is performed after the ethyl esterification reaction. A standstill process is performed to delaminate a product and the ionic liquid, in which an upper-layer esterification product is removed, and a lower-layer ionic liquid can be repeatedly utilized to perform the ethyl esterification reaction. Accordingly, the product can be separately delaminated from super acidic catalyst, and the catalyst can be recycled and reused, thereby solving problems such as product separation, waste acid treatment and facility corrosion and effectively promoting esterification productivity.

Title: Method of controlling optical power and extinction ratio over full temperature range
Inventor: Cai wei-hong
IPC: H01S5/068
Filed: 2012-03-05
Abstract: The present invention discloses a method of controlling optical power and extinction ratio (ER) over a full temperature range. The method is applied to a fiber optic transceiver electrically connected with and controlled by an electronic device to generate or receive a laser beam. The fiber optic transceiver includes a TOSA (Transmitter Optical Subassembly), a laser driver, a controller IC and a thermal sensor, wherein the TOSA is equipped with a laser diode, while no monitoring photodiode is required. The laser driver is controlled by the controller IC for driving the laser diode to generate a laser beam for transmission out through the optical fiber. The thermal sensor is used for sensing the temperature of the laser diode. The disclosed method is based on factory characteristics data of the fiber optic transceiver or the laser diode, namely the threshold current under a plurality of specific temperature and their corresponding slope efficiency (SE), to obtain the threshold current over the full temperature range and its corresponding slope efficiency by using an approximation approach, thereby obtaining the relationship between optical power and conduction current of the laser diode over the full temperature range. At room temperature, the bias current and the modulation current of the laser diode are manually adjusted, so that the laser diode can generate the desired optical power and extinction ratio at room temperature, thereby determining the operation parameters, such as the bias current, the modulation current and so on, over the full temperature range. The aforementioned relationship and operating parameters are written into one memory of the controller IC (or the electronic device). Thus, by using the thermal sensor to obtain the current temperature of the laser diode, the controller IC can control the laser driver according to the foregoing relationship and operating parameters, so that the laser driver can drive the laser diode and enable the laser diode to generate a laser beam that has the expected optical power and extinction ratio.

Title: Frame element length transmission in audio coding
Inventor: NEUENDORF MAX
IPC: G10L19/02
Filed: 2012-03-19
Abstract: Frame elements which shall be made available for skipping may are transmitted more efficiently by arranging that a default payload length information is transmitted separately within a configuration block, with the length information within the frame elements, in turn, being subdivided into a default payload length flag followed, if the default payload length flag is not set, by a payload length value explicitly coding the payload length of the respective frame element. However, if the default payload length flag is set, an explicit transmission of the payload length may be avoided. Rather, any frame element, the default extension payload length flag of which is set, has the default payload length and any frame element, the default extension payload length flag of which is not set, has a payload length corresponding to the payload length value. By this measure, transmission effectiveness is increased.

IPC: B04B1/04
Filed: 2012-04-05
Abstract: This invention relates to a mixture separation method of vertical centrifuge, having a main body which is disposed therein with a rotation drum utilizing high-speed rotation to separate the mixture. The rotation drum has a shaft portion at the upper part, and the lower part of the shaft portion is connected with a separation portion. The upper side of the main body is disposed therein with a shaft seat, and the shaft portion of the rotation drum is pivotally connected to the shaft seat. When the centrifuge is separating the mixture, the rotation drum is rotated in high-speed rotation and poured by the interface liquid with high specific gravity, making the interface solution formed as the stopper portion on the inner wall of the separation portion. Moreover, the mixture is poured into the rotation drum so that the mixture is moved towards the inner wall of the separation portion by means of the action of the centrifugal force generated by the rotation drum. At this time, the heavy-phase liquid in the mixture is blocked on the surface of the stopper portion due to its specific gravity being lower than that of the interface liquid, while the solid impurity in the mixture will pass through the stopper portion and be accumulated on the inner wall surface of the separation portion, so as to enhance the separation efficiency of the heavy-phase liquid and the impurity of the mixture.
