  • Patent number: 7702715
    Abstract: A variable radix divider uses dividend, divisor and quotient as division operators and includes an adder/subtractor having inputs of the dividend and the divisor. The divider further includes a first and second quotient/radix generator having inputs of the dividend and the divisor, a first multiplexer having input of the output from the first quotient/radix generator, and a second multiplexer having input of the output from the second quotient/radix generator. The first and second generators each includes a prediction adder/subtractor having inputs of bits in prediction range of the dividend and bits in prediction range of the divisor, a radix generator, and a quotient generator. The radix generator and the quotient generator have input of the output of the prediction adder/subtractor. The divider iterates a recursive cycle operation until the division operation through a feedback path to the dividend is completed.

  • Patent number: 7636213
    Abstract: A recording current optimization method to optimize a recording current according to a change of a driving voltage applied to a pre-amplifier that generates the recording current supplied to a head, a recording medium storing a program that executes the method, and an apparatus that employs the method. The method of optimizing the recording current provided to the recording head of the hard disk drive includes detecting a driving voltage of the pre-amplifier, determining a voltage difference between the detected driving voltage and a reference driving voltage of the pre-amplifier, and optimizing the recording current according to the determined voltage difference. The recording current is adaptively optimized according to the change of the pre-amplifier driving power to provide the recording current to the head such that adjacent track erasure (ATE) and weak write (WW) are prevented from occurring due to the change of the driving power.

Inflow water and return water are supplied into the gas holder to make the mixture gas dissolved in the inflow water and the return water. The return water was provided from a granulation biological reaction tank. The inflow water and the return water including the dissolved mixture gas are transported to the granulation biological reaction tank. A nitrogen-based component is removed from the inflow water and the return water using methan-oxidizing bacteria granulated in the granulation biological reaction tank. Treated water without the nitrogen-based component is transported to an anoxic tank for treatment, and discharged from the anoxic tank.

  • Patent number: 7490357
    Abstract: For protecting data within a data storage system, such as a hard disk drive, security enable mode is entered. In that mode, initialization data is moved from a first area of a disk to a second area of the disk with a location of the second area being randomly generated. The initialization data is then erased from the first area. Also, a first cipher for firmware and a second cipher for a disk are both changed into a randomly generated value. Later, access to the initialization data from the second area is granted in the security enable mode if the first and second ciphers are the same.
