The vibration preventing device comprises a screw slot(103) in a panel frame(104); a through hole(113) in an upper flange(112); a screw(119) to fix the cabinet cover(111) by combining with the through hole(113) with the screw slot(103); a supporting pipe(109) combined with a frame(106) to assemble the cabinet cover(111) in an exact position; and a combining slot(118) in a lower flange(117) to fix the lower flange(117) in a low cover(121) through the screw(119). The holder is combined with the keyhole and the inserting slot is combined with the supporting pipe. The upper flange is fixed in a control panel and the panel frame with the screw. The lower flange is fixed with the low cover with the screw.

Title: Semiconductor memory device which is tested by selecting one of multiple group data input-output channels

Abstract: PURPOSE: A semiconductor memory device is provided to reduce the number of data input/output channels and to test all data input/output circuits within the device. CONSTITUTION: Plurality groups of data input buffers DIN BUFs buffers data carried on the input/output channels. A first group of write multiplexers WMUXs, responsive to control signals in which any one is activated at a test mode, stores the buffered data in a memory cell. A first group of read multiplexers RMUXs, responsive to the control signals, reads the data stored in the memory cell. Plurality groups of data output buffers DOUT BUFs buffers the data outputted from the read multiplexers RMUXs to output the same to the input/output channels. A group of comparators COMPs operates at the test mode, receives the data from the memory cell, compares the data with one another and outputs the compared result to the read multiplexers RMUXs.
