Abstract: A CPU core voltage supply circuit includes a reference voltage generator, a differential operation amplifier, a power element, a feedback circuit and a first capacitor. The reference voltage generator outputs a first reference voltage. The differential operation amplifier has a positive input end, a negative input end and an output end. The positive input end is connected to the reference voltage generator for receiving the first reference voltage. The power element has a receiving terminal and a current output terminal. The receiving terminal is connected to the output end of the differential operation amplifier. The feedback circuit is connected to the current output terminal and outputs a feedback voltage to the negative input end of the differential operation amplifier. The first capacitor has an end connected to the current output terminal of the power element and the other end receiving a first voltage, thereby providing a CPU core voltage.

Abstract: The present invention is directed to a process for forming a durable layer on an article in an in-mold decoration process. The process comprises the steps of: a) thermally curing a composition comprising (i) an amino crosslinker and (ii) a UV curable monomer or oligomer having at least one functional group reactive with the amino crosslinker, in the presence of an acid catalyst to form a durable layer; b) transferring the durable layer to the surface of an article formed by an injection molding process carried out in a mold; and c) curing the durable layer by radiation.

Abstract: The invention relates to electrophoretic displays comprising core-shell pigment particles having a core of low specific gravity and low refractive index and a shell of high refractive index.
