    摘要： A semiconductor memory device and a parallel bit test method thereof comprises a memory cell array having a plurality of memory cells, an address generator for accessing memory cells of the memory cell array in response to externally applied addresses; a test mode setting register for storing an externally applied test mode setting command; a test pattern data register for storing test pattern data applied from the test mode setting register and for outputting test pattern data at the time of performing a read command; and a comparator for comparing data read from the memory cells of the memory cell array with data of corresponding bits of test pattern data output from the test pattern data register and for generating test result data. Accordingly, the device is adapted for correctly detecting and distinguishing defective memory cells, and is amenable to performing bit tests using various non-uniform test pattern data.

    摘要： A vehicle auxiliary horn apparatus provides a sound through a horn to alert pedestrians that a vehicle, such as an electric vehicle or a new vehicle that makes virtually no noise, is moving; and provides set sound information during parking when a human body is detected. The vehicle auxiliary horn apparatus of the present invention comprises: a sound storage unit for storing and managing music information, announcement information, and repeating sound information; a display panel unit for displaying information for setting one type of sound information stored in the sound storage unit; a sound extracting unit for extracting the sound information, selected from the display panel, from the sound storage unit; a sound output processing unit for outputting the sound extracted from the sound extracting unit through a speaker; a manual control unit disposed on the front portion of the vehicle, for transmitting a manual control signal to a central control, unit when manipulated; an automatic control unit disposed on the front portion of the vehicle, for transmitting an automatic control signal to the central control unit, when manipulated; a sound-providing, speed-setting unit for setting a speed for automatically outputting a sound, under automatic control; a moving speed checking unit for checking the moving speed of the vehicle; and the central control unit for receiving a control signal transmitted by the manual control unit or the automatic control unit, distinguishing the type of the control signal, and when the control signal is an automatic control signal, acquiring the speed information set by the sound-providing, speed-setting unit, checking the current speed, and determining whether to output a sound. Through the present invention, by providing a sound through a horn to alert pedestrians that a vehicle is moving, such as an electric vehicle or a new vehicle that makes virtually no noise, the effect is provided of being able to prevent the occurrence of dangerous situations for pedestrians. Also, in school zones, on roads within apartment complexes, on roads in which there are many pedestrian walkways, and the like, in which it is difficult to use a typical loud horn while a vehicle is moving slowly, the auxiliary horn can be used in a practical manner to provide better results. In particular, the effect is provided of being able to assist the safe movement of those who cannot focus well on the surrounding traffic conditions in which they walk and those whose reactions and movements are slow, such as children, patients, and the elderly, and the disabled who require care and protection.

    摘要： A graphite golf club which is formed on a mandrel is provided. The graphite golf club comprises a club head which strikes a golf ball; a club shaft which comprises a coupling unit to be coupled with the club head and a main body unit extending from the coupling unit to a golf club grip. The mandrel includes a mandrel joint unit which is formed with mandrel steps that decrease in diameter from one end of the mandrel to the other end of the mandrel. The golf club shaft is formed on the mandrel with a lower sheet layer contacting and overlapping the mandrel and an upper sheet layer overlapping an outer part of the lower sheet layer. The lower sheet layer and the upper sheet layer form a sheet joint unit which includes sheet steps decreasing in diameter corresponding to the mandrel steps.
