Filed: 1986-07-14
Abstract: PURPOSE:To improve the sensitivity of resist without varying other characteristics by a method wherein a predetermined light is absorbed by radicals while a radiation is applied and their electron conditions are excited to suppress recombination reaction. CONSTITUTION:For instance, resist 3 is applied to a semiconductor substrate 4 to the thickness of less than 1 mum and prebaked and then exposed to X-rays through an X-ray mask 2. At the same time as the exposure to the X-rays, an ultraviolet radiation is applied to the surface of the sample for exposure and then a resist pattern is obtained by developing. With this constitution, the sensitivity of the resist can be improved without varying other characteristics by a relatively simple method wherein a light which decomposes radicals is applied during the exposure.

Filed: 1988-06-30
Abstract: PURPOSE:To prevent simultaneous production of refresh operation and to decrease a required current capacity at peak by sending a refresh signal given to each memory block of a large capacity memory device comprising plural memory blocks while shifting the phase. CONSTITUTION:Refresh control circuits 11-1n generate a refresh signal of a prescribed period to be sent to D-RAM blocks 21-2n. The refresh control circuits 11-1n consist of counters counting up, e.g., synchronously with a basic clock, the count is started by a reset signal outputted from a refresh initial start control circuit 2 and when the time corresponding to one refresh cycle is counted, a refresh signal is outputted and the counter restores the initial value. Then the refresh signals given to each memory block are sent while the phases are deviated. Thus, the simultaneous production of refreshing is prevented and lots of current at one time is avoided.

Filed: 1990-06-22
Abstract: PURPOSE:To assure the always aimed rolling reduction by correcting the roll gap set value of a rolling reduction adjusting device with a roll gap correction value by this rolling reduction adjusting device. CONSTITUTION:While the roll gap G1 is detected by a position detector 8, the roll gap value G2 is set by the rolling reduction adjusting device 5. The roll gap values G1 and G2 are taken in at the timing before the start of the leveling operation of a roller leveler and are inputted to an arithmetic controller 9. The roll gap correction value  G is previously calculated from both roll gap values G1, G2 in the arithmetic controller 9. The setting of the roll gap correction value  G involves separately inputting conditions, such as rolling size, steel kind and further finish temp. of a material S to be leveled, in the same manner as heretofore at the time of the leveling operation and setting the reference roll gap value G3 based on the rolling reduction reference according to these conditions. This reference roll gap value G3 is corrected by the roll gap correction value  'G and the set roll gap value G4 is computed. This value is outputted to the rolling reduction adjusting device 5 and the rolling reduction thereof is controlled.
