Title: Clock transfer system for plasma display
Inventor: YOSHIDA HIROKI
IPC: G09G3/28
Filed: 1988-09-13
Abstract: PURPOSE:To prevent the trouble of unnecessary radiation on a clock transfer path by transferring a clock signal which is outputted from a device main body side while reducing its voltage and then driving a plasma display panel by boosting the voltage. CONSTITUTION:The clock (CLK) of TTL level for display control which is outputted from a clock module 1 is supplied to a controller 2 for display data transfer and also supplied to a 1V converting circuit 3. The 1V converting circuit 3 converts the clock (CLK) of TTL level (about 5V) for display control into a low-voltage clock (L-CLK) of 1 VP-P, which is transferred to a 5V converting circuit 6 provided on the side of a display device B through the clock transfer path 4. The 5V converting circuit 6 boosts the voltage of the low-voltage clock (L-CLK) to the TTL level and supplies it to the clock input terminal of the plasma display unit 7 as a clock (D-CLK) for display control. Consequently, the influence of unnecessary radiation upon the periphery is reduced.

Title: Photoresist
Inventor: SUGIMOTO ARITOSHI
IPC: H01L21/027
Filed: 1987-09-16
Abstract: PURPOSE:To improve resistance to dry etching of a photoresist by incorporating a novolak resin, a diazide compd. and an azide polymer. CONSTITUTION:A cresol type novolak resin expressed by the figure, a diazide compd., and an azide polymer are incorporated into a photoresist. The azide groups in the azide polymer form chemically active nitrene groups by the photolysis when the photoresist after development is exposed to light having shorter wavelength than the light for exposure. A high molecular-forming reaction due to three dimensional crosslinking of the novolak resin with the azide polymer is caused by the reaction of said nitrene with neighboring molecules. By the method, the resistance of the photoresist to dry etching is improved because the photoresist is hardly vaporized even if lowering of mol. wt. of the photoresist is caused by the effect of plasma during dry etching.

Title: Watchdog timer
Inventor: ITOU HACHIDAI
IPC: G06F11/30
Filed: 1988-09-14
Abstract: PURPOSE:To improve the ability to detect the CPU abnormality by detecting this abnormality not only in the case the output interval of the initialization signals is longer than the prescribed time but in the case the output interval is shorter than the prescribed time. CONSTITUTION:The count value of a counter 4A is cleared by the input of an initialization signal 2 and the counter 4A starts counting again at 0 to output a signal S4A after the time T1. In the same way, a counter 4B outputs a signal S4B after the time T2 (T2<T1). A CPU 1 repeats the operations in a cycle of >=T2 and <=T1 and is programmed to output the signals 2 in this cycle. Therefore the time set at a certain time point between the output of a signal 2 and the output of the next signal 2 is usually set at >=T2 and <=T1. Thus no abnormality detecting signal is outputted. Then an abnormal signal is outputted in the case the interval of the signal 2 is set at >=T1 or <=T2. Thus the abnormality detecting ability is improved since the abnormal signal is outputted even with the time less than T2.
