    • The light emission panel display device according to the present invention has a scan drive circuit (30) driving a selected scan line to a selected voltage and unselected scan lines to a non-selected voltage higher than the selected voltage in each scanning period and (3) a data drive circuit (20) supplying light-emitting drive current to the data lines respectively in the periods of light emission corresponding to display gradation. The data drive circuit (20) starts supply of the light-emitting drive current to the data lines respectively at the emission-initiation timing corresponding to the emission period in the scanning period, and terminates supply of the light-emitting drive current to the multiple data lines at the same emission-termination timing. In addition, the scan drive circuit (30) maintains the selected scan line to an emission-termination voltage higher than the selected voltage and terminates light emission of the light-emitting element connected to the selected scan line at the emission-terminating timing. It is thus possible to prevent continuous light emission of the light-emitting element emitting light by electrical charging and discharging at the emission-termination timing during light emission.

    • When signal transmission is performed between two semiconductor integrated circuit devices in synchronization with a clock signal using a small signal amplitude relative to an operating voltage of the two semiconductor integrated circuit devices, a received signal is held in the receiving semiconductor integrated circuit device in synchronization with the clock signal while the small signal amplitude of the held signal is kept substantially without change. The received signal having the small signal amplitude is amplified along a signal transmission path including a combined logic circuit to a subsequent latch circuit of the receiving semiconductor integrated circuit device.

    • A semiconductor integrated circuit device having an input/output circuit for inputting and outputting data having a GTL level includes a pull-down output MOSFET (Q1) and a pull-up output MOSFET (Q2) both electrically connected to an input/output terminal and a gate drive signal generating circuit (DPG) electrically coupled to the gate of the pull-up output MOSFET (Q2). Upon data transmission, the gate drive signal generating circuit (DPG) controls the operation of the output MOSFET (Q2) so that the output MOSFETs (Q1 and Q2) are contemporarily brought into an ON or OFF state according to data to be transmitted. On the other hand, upon data reception, the gate drive signal generating circuit (DPG) forms a control pulse for temporarily turning ON one of the output MOSFETS (Q2) immediately after high-level data has been received, and supplies it to a gate terminal of the output MOSFET (Q2).

    • The first invention provides a substrate for a magnetic recording medium, which is prepared by forming a macro-concavo-convex pattern for improving CSS properties and a micro-concavo-convex pattern for improving magnetic properties on the surface, thereby preventing the degradation of the CSS properties brought by the enhancement in friction coefficient and the increase in the area of a protective layer of the medium in contact with a magnetic head, caused by the wearing of the protective layer of the medium.The second invention provides a process of producing a substrate for a magnetic recording medium, which forms the above macro-concavo-convex pattern and micro-concavo-convex pattern in a uniform distribution at the same time.The first invention utilizes, as the texture, protrusions 13P and 15P different in length from the substrate surface, the protrusions being prepared by packing at least two kinds of materials 13 and 15 differing in etching rate into alumite pores 14A and 14B, polishing and then etching.The second process invention comprises the steps of packing the first material into alumite pores of an aluminum alloy by means of electrolytic deposition, packing the second material having an etching rate different from that of the first material by means of dipping method, polishing the resultant surface and etching the polished surface so as to make the respective protrusion lengths of the first and the second materials within the predetermined range.

    • An Nth one of N parallel sequences of low-speed data demultiplexed by a demultiplexer from high-speed input data in synchronization with a high-speed clock is compared by N comparators with N parallel sequences of reference patterns. The N parallel sequences of reference patterns are each generated in synchronization with a frequency divided clock obtained by frequency dividing the high-speed clock into 1/N. When any of the comparators provides a disagreement output at least once, one clock pulse is eliminated by a post-clock eliminating circuit from the divided clock so that the N sequences of reference patterns are each delayed by one bit. When a counter detects that any one of the comparators does not provide the disagreement signal for n consecutive bits, the sequence of reference patterns corresponding to this comparator and the Nth sequence of low-speed data are in synchronization with each other. Clock pulses of the number corresponding to the line position of the synchronized sequence of reference patterns are eliminated by a pre-clock eliminating circuit from the high-speed clock which is applied to the demultiplexer. By this, line positions of the N parallel sequences of low-speed data are sequentially shifted so that the Nth sequence of low-speed data assumes the same line position as that of the synchronized reference pattern, and as a result, the N parallel sequences of low-speed data are synchronized with the N parallel sequences of reference patterns, respectively.
