Apparatuses and methods for detecting error events in a codeword reproduced by perpendicular magnetic recording medium (PMR. The method includes: generating cyclic redundancy check (CRC) parity bits based on a generator polynomial for a source information sequence to be recorded on PMR medium and recording a codeword in which the generated CRC parity bits are added to the source information sequence; and reading the recorded codeword and an error event in the read codeword. It is possible to detect error events when a codeword recorded by PMR is read, using a small number of bits.

The present invention provides an antistatic deposition method of a wireless terminal component, which comprises depositing tin (Sn) or a tin-aluminum (Sn—Al) alloy on a molded material for a wireless terminal component. Also, the present invention discloses an antistatic deposition method of a wireless terminal component, which comprises: depositing tin (Sn) or a tin-aluminum (Sn—Al) alloy on a molded material for a wireless terminal component; and depositing one or more materials selected from the group consisting of Si, SiO, Ti, TiO, Al O and a mixture thereof on the deposited tin (Sn) layer or the deposited tin-aluminum (Sn—Al) alloy layer. The antistatic deposition method of a wireless terminal component according to the present invention has advantageous effects in that it overcomes the problems of the prior art that generation of static electricity adversely affects the performance of the inner circuits of the wireless terminal in case where a metal such as nickel (Ni), chrome (Cr) or the like is deposited on a wireless terminal component so as to create a mirror effect, and in that it can maintain an mirror effect and the performance of radio frequencies, can prevent peel-off of a tin (Sn) or tin-aluminum (Sn—Al) alloy deposited on a molded material for a wireless terminal component, and can improve scratch resistance and impact resistance of the wireless terminal component.

A method of detecting an occurrence of an error event in data and an apparatus for the same are provided. The method includes: preparing an error detection code wherein syndrome sequences for dominant error events are all different; generating a codeword from source data using the error detection code; detecting the occurrence of the dominant error event in the codeword by checking a syndrome computed from the codeword; and determining a type and likely error starting positions of the occurred dominant error event using the syndrome sequences correspond to the syndrome.

A cyclonic cleaner which includes a cyclone unit enabling a reduction of noise generated from the cyclone unit, and reduction in pressure loss by forming a smooth air flow. The cyclone unit includes a body having an air inlet and an air outlet, a primary cyclone to primarily separate foreign matter from air drawn through the air inlet, a plurality of secondary cyclones to secondarily separate foreign matter from air discharged from the primary cyclone and to discharge the air having the foreign matter removed therefrom through discharge holes of the secondary cyclones, and a noise reduction member positioned in the discharge hole of each secondary cyclone to reduce noise. The cyclone unit also includes a guide plate to allow the air discharged through the discharge holes of the secondary cyclones to be smoothly discharged through the air outlet.

A vacuum cleaner has a discharge flow path and a discharged-air filter optimally positioned to reduce noise. The vacuum cleaner includes a body, a dust collection unit positioned in the body to filter foreign matter, a blower fan unit including a blower fan and a motor to generate suction force, an air vent through which air drawn into the body is discharged, and a discharge flow path to guide the air discharged through a discharge port of the blower fan unit to the air vent. The discharge flow path comprises a space defined between the dust collection unit and the blower fan unit.

The present invention is in the fields of molecular and cellular biology. The invention is generally related to reverse transcriptase enzymes and methods for the reverse transcription of nucleic acid molecules, especially messenger RNA molecules. Specifically, the invention relates to reverse transcriptase enzymes which have been mutated or modified to increase thermostability, decrease terminal deoxynucleotidyl transferase activity, and/or increase fidelity, and to methods of producing, amplifying or sequencing nucleic acid molecules (particularly cDNA molecules) using these reverse transcriptase enzymes or compositions. The invention also relates to nucleic acid molecules produced by these methods and to the use of such nucleic acid molecules to produce desired polypeptides. The invention also concerns kits comprising such enzymes or compositions.

A method for generating a music file includes receiving a melody from a user through a user interface, and generating a melody file corresponding to the received melody. The method further includes generating a harmony accompaniment file responsive to melody represented by the melody file, and generating a music file by synthesizing the melody file and the harmony accompaniment file.
