Abstract:
A rotor has an interior free from invasion of water and is resistant to deformation from applied stresses normally encountered during the operation of a vacuum pump. The rotor comprises a rotor shell formed to conform to an outline of lobes and side-plates for covering transverse ends of the rotor shell. A rotation shaft is secured to the side-plates. A hollow section is formed by the rotor shell and the side-plates which is under a vacuum environment.
Abstract:
PURPOSE: A system for automatically converting a call termination notification signal and a method therefor are provided to evil influence by a noise of a portable communication device by automatically converting the call termination notification signal into vibration when an alert mode overwriter installed at a call termination notification signal restriction zone is sensed. CONSTITUTION: If a call termination signal is received(101), a control unit checks whether a termination mode is set as a sound(102). If the termination mode is set as the sound, the control unit controls an alert mode sensor and performs an inquiry scan during a uniform time to an inquiry access code(103). If an inquiry scan notification is generated from the alert mode sensor(104), the control unit controls a vibration driving unit and a vibrator and generates a vibration(106). If the inquiry scan notification is not generated within the set longest time, the control unit controls a sound driving unit and a speaker and generates the sound(107). The control unit performs a corresponding function for processing a termination call(108).
Abstract:
PURPOSE: A simplified connection setup method between Bluetooth devices is provided to convert address information, allocated to each Bluetooth device, into a simple previous identification code. CONSTITUTION: If a user inputs the other side Bluetooth device's previous identification code in his Bluetooth device(500), the user Bluetooth device broadcasts an inquiry packet to neighboring Bluetooth devices(510). If inquiry response packets are received from the neighboring Bluetooth devices, the user Bluetooth device acquires address information for each Bluetooth device from each inquiry response packet and extracts each previous identification code from the acquired address information. The user Bluetooth device compares each extracted previous identification code with the inputted previous identification code(530). If an extracted previous identification code is matched with the inputted previous identification code, the user Bluetooth device checks whether information for a Bluetooth device having a previously searched identical previous identification code is stored(532). If previously stored information exists, the user Bluetooth device judges whether one of the Bluetooth devices having previously stored information is matched with the Bluetooth device of the matched previous identification code(534).
Abstract:
A method and an apparatus for mapping a flash memory are provided to perform wearing equal even if using a smaller number of counters rather than the number of physical blocks of the flash memory. An apparatus for mapping a flash memory(230) includes a smaller number of counters than the number of physical blocks of the flash memory and a control part(210). The control part changes the value of at least one counter in correspondence to an erase command for at least one physical block of the flash memory, and maps at least one physical block to a logic block on the basis of the value of the counters.
Abstract:
A method for reading data of a nonvolatile storage device is provided to synchronize data transmission by operating a storage FSM(Finite State Machine) and a host FSM in parallel without firmware change, by using a register capable of being accessed by the storage FSM and the host FSM at the same time as a time stamp register. According to a method for reading data of a nonvolatile storage device(330), data of a first number of blocks are read from the nonvolatile storage device and then data of the blocks are stored in a data buffer(360). In correspondence to storage the block data in the data buffer, first time stamp is increased and is stored in a time stamp register(370). It is determined to transmit the data of the blocks stored in the data buffer to a host(310), by comparing the first time stamp with second time stamp.
