Method of partially converting wood into plastic material by impregnating the wood with a phenol and substances which form a reaction product which forms a prepolymer with the lignin in the wood, heating said impregnated wood to form said reaction product and pre-polymer, and thus applying further heat and pressure to said impregnated wood to form a copolymer between said pre-polymer and the lignin in said wood.
摘要:
An image processing system includes an image sensor circuit. The image sensor circuit is configured to obtain an image using a type of shutter operation in which an exposure pattern of a pixel array is set according to exposure information that changes over time based at least partially on charge accumulated in at least a portion of the pixel array. An image sensor circuit includes a pixel array and one or more circuits. The one or more circuits are configured to update exposure information based at least partially on one or more signals output from the pixel array, and to control an exposure pattern of the pixel array based on the exposure information. A pixel circuit includes a first transistor connected between a photodiode and a sense node, and a second transistor connected between an exposure control signal line and a gate of the first transistor.

Circuits and methods are provided for implementing highly efficient switch-mode power amplifiers using BJTs (bipolar junction transistors) as active switching devices at millimeter-wave frequencies. More specifically, circuits and methods are provided for driving power amplifiers with BJT switching devices to achieve highly efficient switch-mode (e.g., Class E) operation at millimeter wave frequencies (e.g., 60 GHz).

The invention relates to a method for producing a flow containing at least one alkene derivative, including the following steps: a step a) of reacting a flow containing one or more alkenes and one or more alkanes—the ratio of said alkanes to said alkenes being at least 1 by volume—with a flow containing mainly oxygen, in order to obtain at least one converted flow containing at least said alkene derivative; a step b) of separating the converted flow produced in step a) into at least said flow containing at least said alkene derivative and a residual flow containing mainly one or more hydrocarbons and one or more inert compounds; and a step c) of separating all or a portion of said residual flow by means of permeation into at least one first flow containing mainly one or more inert compounds and a second flow containing mainly one or more hydrocarbons.
