Title: Spatial frequency characteristic setting method and setting method for digital filter
Inventor: TAKITA HIROAKI
IPC: H04N1/409
Filed: 1995-06-21
Abstract: PURPOSE: To distinctively grasp the quality of an image by determining the frequency and intensity of a peak and a cutoff frequency, and then connecting them smoothly with respective functions. CONSTITUTION: Image input is performed first by using a scanner (step S1), but input spatial frequency characteristics of the scanner need to be grasped distinctively so as to obtain an image with target spatial frequency characteristics to the end. For the purpose, the spatial frequency characteristics of the scanner are approximated with a mathematical expression as shown in a step S11. After the spatial frequency characteristics of the image data inputted by the scanner are determined, target spatial frequency characteristics of the image are determined next (step S12). Thus, the target spatial frequency characteristics are selected and then the digital filter is designed next (step S13). Thus, the frequency and intensity of a peak and the cutoff frequency are determined and they are connected smoothly with the specific function.

Title: Oxygen densitometer
Inventor: MIYAI JINKICHI
IPC: G01N27/26
Filed: 1988-06-24
Abstract: PURPOSE:To enable stable measurement of a very small amount of oxygen by covering the surface of a cathode of an electrode for causing an oxygen electrolysis with an anion exchange film. CONSTITUTION:The surface of a cathode 6 of an electrode 4 for causing electrolysis for adjusting a reference gas dipped into an alkaline solution 8 is covered with an anion exchange film 16. The exchange film 16 uses an array of an anion exchange group such as quarternary ammonium group on an ion transmitting mother film, for instance. In a densitometer 1 using the electrode 4, 26.7muA of current flows through the electrode 4 sampling a nitrogen gas containing no oxygen at a flow rate of 100ml/min to generate a reference gas with an oxygen concentration of 1ppm continuously. In this case, even after more than 10hr passes, there is no reduction in the quantity of oxygen generated. When the apparatus is used more than one month performing a generation of oxygen as desired, no drop in the generation level of oxygen is noted and there is no blackening in the surface of the cathode of the electrode 4. Thus, a desired density of a reference gas is obtained stably and the concentration of a very small amount of oxygen can be measured accurately by a precise calibration.

If the content is 1, the subtraction counter is subtracted by one with the input from the gate 17 and it is stored in the corresponding memory area again when the one set pulse mS is present in the m-th line in the lines 1S, 1R- nS, nR. Further, the memory area for the m+1-th line is read out in the next timing. If the content of the counter 19 is 0, the reset pulse mR is made and the dial pulse is formed at the post stages.

Title: Manufacture of dram with automatic alignment electrodes
Inventor: SHIYOU KAJIYUN
IPC: H01L21/768
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To increase the capacitance of a capacitor and to obtain a DRAM having high integration density by simultaneously forming the upper layer electrode and bit contact of a capacitor with one lithography mask. SOLUTION: A third insulating layer 60, a second insulating layer 58, a doped second polysilicon layer 56 and a first insulating layer 50 are etched by using lithography and a plasma etching technology. The plasma etching is stopped on the surface of an n<+> type highly doped drain 44B, thereby forming a bit line contact 61. At this time, an upper layer electrode 56 of the capacitor is formed. The automatic alignment structure of the electrode 56 and the contact 61 is formed, thereby remarkably increasing the area of the electrode 52 of the capacitor at the time of memory device contraction. Thus, the capacitance of the capacitor is increased, and hence the DRAM of high integration density can be obtained.

CONSTITUTION:A rolling material 6 is rolled, while adjusting a roll gap of work rolls 5 and back up rolls 4 by moving a ram 3 housed in a rolling reduction cylinder 2. The position SM of the ram 3 is measured by a measuring instrument 7 to reversely feedback its result to a sheet-thickness command Ho, and on the other hand, a rolling load FM is measured by an instrument 8 to rversely feedback the result, obtained by dividing said measured result by a mill constant with the aid of a counter 9, to an adder, thereby controlling the roll gap so that the equations are held, then the sheet thickness is kept constant. Here, a load correcting value F' is added from a computor 13 to the FM to be inputted to an adder 113, placed between the instruments 8, 9, to impress the result of the adder 113 onto the measuring instrument 9. The computor 13 reads the FM, SM at the fixed time intervals to detect the increasing and decreasing directions of the roll gap, thereby calculating a correcting hysteresis amount (F') basing on the FM, SM obtained at the time of the reverse turn, which are put as the reference points, to output the results to the adder 113.
