摘要： The plasma display panel having brightness display ranges comprising a gradation brightness display range which displays gradation brightness corresponding to the input signals under a preset input signal level and a constant brightness display range which displays a constant peak brightness greater than the maximum brightness corresponding to input signals greater than the preset input signal level. The plasma display panel can provide the gradation display up to the maximum brightness corresponding to the input signals up to the maximum input and provide the constant peak brightness corresponding to the peak level input by adding one additional weighting bit for the higher gradation. Consequently, a high quality brightness display with high mean value of the brightness and sufficiently high peak brightness can be achieved. Furthermore, the plasma display panel enhances the brightness weighting value and the value of .gamma. for the reverse .gamma. correction when the input signals go over the preset value and decrease the values to the original values when the input signals drop below the preset value. The plasma display panel can provide the gradation display up to the maximum brightness corresponding to the input signals up to the maximum input signal and provide the gradation display up to the peak brightness greater than the maximum brightness corresponding to the input signals over the maximum input signal. Consequently, high quality display with high brightness and high contrast without exceeding the maximum permissible power consumption can be achieved.

摘要： A test pattern generation circuit outputs a test pattern during a clock phase adjustment period. A flip-flop circuit latches the test pattern at the fall of a shift clock and outputs it as a test pattern. A latch miss detection circuit outputs a latch miss detection signal indicating presence/absence of a latch miss generation according to the test pattern and a delay shift clock. A clock phase controller delays the shift clock according to the latch miss detection signal, thereby outputting a delay shift clock.

摘要： A test pattern generation circuit (100) outputs a test pattern (TP) during a clock phase adjustment period. A flip-flop circuit (110) latches the test pattern (TP) at the fall of a shift clock (SCK) and outputs it as a test pattern (Tpa). A latch miss detection circuit (130) outputs a latch miss detection signal (LM) indicating presence/absence of a latch miss generation according to the test pattern (TPa) and a delay shift clock (DSCK). A clock phase control section (120) delays the shift clock (SCK) according to the latch miss detection signal (LM), thereby outputting a delay shift clock (DSCK).

摘要： A disclosure is made of a subterranean connecting method and a connecting apparatus therefor which are suitable for use when two shield machines are used to excavate a pair of tunnel sections from both ends of a tunnel, and the tunnel sections are connected to each other in mid course. During underground connection, it is important to secure sealing and water retarding with respect to soil and water pressure exerted by the ground in the vicinity of the connecting section. For this purpose, in the connecting apparatus, a penetration ring is arranged in one of the shield machines, and a penetration chamber in which the penetration ring is accommodated is arranged in the other shield machine. Both the both shield machines face each other with a slight gap remaining therebetween and, subsequently, the penetration ring is moved forward and penetrates into the penetration chamber of the mating shield machine. By this penetration, the area between both the shield machines are closed by the penetration ring. In this condition, both the shield machines are disassembled, and the wall surface of the connecting section including the penetration ring is covered, so completing the subterranean connecting step. According to the connection using such a penetration ring, sealing and water retarding with respect to the soil and water pressure in the vicinity of the connecting section can be secured.
