Abstract: PURPOSE:To facilitate maximization of the area of a storage capacitor by forming the storage capacitor pattern when a plate electrode is processed. CONSTITUTION:A conventional manufacturing method is adapted until an interlayer insulating film 5 is formed. Then a single storage capacitor 7 for a pair of memory cells having one bit line in common is formed. A capacitor insulating film 8 and a plate electrode 9 are formed on the storage capacitor 7. When an aperture for providing the contact of the bit line is formed, the plate electrode 9 and the storage capacitor 7 are processed simultaneously to divide the storage capacitor 7 into the respective storage capacitors for a pair of the memory cells. Thus, by forming the aperture, the plate electrode and a pattern at one end of the plate electrode are formed. With this constitution, the storage capacitors can extend to the aperture so that the larger storage capacitance can be realized with the same cell area.

Title: Controller for husking roll gap
Inventor: MAEDA KOSAKU
IPC: B02B7/00
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To prevent the uneven wear and excessive wear of husking rolls by detecting the work stability state of the husking rolls during the initial gap setting of the roll gap and correcting the reference value of an automatic roll gap control means in accordance with the result of the detection. SOLUTION: The data at the time of contact of the husking rolls during the initial roll gap control is detected by a work stability sensor. If the result is larger than the reference value, the control time intervals of the automatic roll gap controller are so corrected as to be prolonged. When the result is smaller than the reference value and the husking work is stable, the control time intervals are so corrected as to be shortened. When the operation is shifted to the roll gap control by a load current value reference, the detection command of the load current value is emitted at every corrected correction time interval from a control section 41 and the load current value is detected by a load current sensor 32.  When the detected load current value is higher (lower) than the reference value, a roll gap control motor 37 is controlled to an open side (close) side for the prescribed time and the roll gap is so associatively controlled as to be reset the detected load current value to the reference value.
