    摘要: The present invention provides a method for identifying a thermostable polymerase having altered fidelity. The method consists of generating a random population of polymerase mutants by mutating at least one amino acid residue of a thermostable polymerase and screening the population for one or more active polymerase mutants by genetic selection. For example, the invention provides a method for identifying a thermostable polymerase having altered fidelity by mutating at least one amino acid residue in an active site O-helix of a thermostable polymerase. The invention also provides thermostable polymerases and nucleic acids encoding thermostable polymerases having altered fidelity, for example, high fidelity polymerases and low fidelity polymerases. The invention additionally provides a method for identifying one or more mutations in a gene by amplifying the gene with a high fidelity polymerase. The invention further provides a method for accurately copying repetitive nucleotide sequences using a high fidelity polymerase mutant. The invention also provides a method for diagnosing a genetic disease using a high fidelity polymerase mutant. The invention further provides a method for randomly mutagenizing a gene by amplifying the gene using a low fidelity polymerase mutant.

    摘要: A position control device includes a fluid-operated directional control valve for controlling the position of the piston of a cylinder assembly under fluid pressure in response to a control signal from an electronic controller. The position of the piston is predicted based on the control signal. A position detector detects when the piston has actually reached a predetermined position. When it is detected that the piston has actually reached the predetermined position, the predicted position of the piston is corrected. The electronic controller applies a control signal to the directional control valve so that the predicted position as corrected will be equalized to a target position for the piston. The predetermined position is a substantially intermediate position of the stroke of the piston. The directional control valve comprises a solenoid-controlled valve for controlling the flow rate of the fluid depending on the magnitude of a current supplied to the solenoid-operated valve. The position of the piston is calculated based on the magnitude of the current and a period of time during which the current is supplied to the solenoid-operated valve. An automotive suspension system incorporating the position control device is also disclosed.
