    • A writing current circuit (42) supplies a controlled electrical current to a laser diode (34) for recording data swiftly onto a DVD (16). A plurality of current sources (62) in the writing current circuit (42) supply electrical current to the laser diode (34). Each current source (62) respectively receives a single output signal from a current control register (52) included in the writing current circuit (42) which activates or deactivates the current source (62) for supplying a particular quantity of electrical current to the laser diode (34). In each current source (62), electrical current flows to the laser diode (34) through a MOSFET output transistor (142) connected in series with the laser diode (34). Each current source's MOSFET output transistor (142) has a gate insulating layer which is thinner than the gate insulating layer conventionally used for a MOSFET output transistor (142) that is energized by the electrical potential ths it applied to the writing current circuit (42).
    • 写入电流电路(42)将受控的电流提供给激光二极管(34),用于将数据迅速地记录到DVD(16)上。 写入电流电路(42)中的多个电流源(62)向激光二极管(34)提供电流。 每个电流源(62)分别从包括在写入电流电路(42)中的电流控制寄存器(52)接收单个输出信号,其激活或去激活用于向激光器提供特定数量的电流的电流源(62) 二极管(34)。 在每个电流源(62)中,电流通过与激光二极管(34)串联连接的MOSFET输出晶体管(142)流到激光二极管(34)。 每个电流源的MOSFET输出晶体管(142)具有栅极绝缘层,其比通常用于MOSFET输出晶体管(142)的栅极绝缘层薄,该栅极绝缘层被施加到写入电流电路(42)的电位激励, 。

    • Methods of utilizing reduced cellulase loads to hydrolyze cellulosic substrates are disclosed. The methods include determining an amount of purified cellulase necessary to substantially hydrolyze a quantity of cellulosic substrate in a period of time; reducing the amount of purified cellulase by a factor of between 2 and 5 to determine a reduced cellulase load; and introducing to the cellulosic substrate either (1 ) a microorganism expressing cell-bound cellulase in a concentration equal to the reduced cellulase load or (2) a fermentation agent that has been engineered to express cell-bound cellulase in a concentration equal to the reduced cellulase load under suitable conditions and for said period of time sufficient to allow substantial hydrolysis of the cellulosic substrate.
