IPC: H01L21/027
Filed: 1995-02-14
Abstract: PURPOSE: To provide a method for controlling line dimensions in a photolithographic process wherein a wafer coated with photoresist chemically amplified is used. CONSTITUTION: This method includes a process, in which a growth signal including strength of light diffracted from a portion of an exposed patterned region on a wafer 18 is measured at least two times from at least two angles. The growth signal corresponds to sum of the vector of a light which is diffracted by a pattern, occurring in a photoresist and varies with time and a light which is diffracted by a pattern under the photoresist and does not vary substantially with time. Then the measured values are combined mathematically to derive a contribution of a pattern formed in the photoresist.

Title: Drive controller for brushless motor
Inventor: MAEDA TETSUO
IPC: H02P6/06
Filed: 1982-02-19
Abstract: PURPOSE:To prevent a brushless motor from damaging by interrupting the drive current when the output frequency of the position detector of the motor becomes higher than the predetermined constant value or when the drive circuit is extraordinarily heated. CONSTITUTION:When a drive circuit 1 and a brushless motor malfunctions so that the motor runs away, the output frequency from a position detector 4a becomes extraordinarily large with the result that the output of a frequency/ voltage converter 5 becomes large, and a positive output is produced from a comparator 7. Since a transistor 8 and a heat sensitive thyristor 10 are conducted by this output, the base of a transistor 11 is grounded, the transistor 11 is interrupted, and the power supply to the drive circuit 1 is interrupted. When the motor is stopped due to some cause or other so that a large current flows, the heated part of the drive circuit 1 is abnormally heated, the thyristor 10 is self- conducted, and the transistor 11 is similarly interrupted to be turned OFF.

Abstract: PURPOSE:To prevent generation of an abnormal local elongation of a cold rolled steel tape in a skin-pass rolling stage by changing the polarity of >=2 pair of the electrolytic electrode in an electrocleaning bath prior to performing box annealing for each one pair of the electrode successively in order to retard in this way the decrease of the electrolytic current. CONSTITUTION:A steel tape S with has been cold-rolled is, prior to performing box annealing, treated in a cleaning bath for electrocleaning using sodium silicate as a base material in order to clean the steel tape S as well as to prevent burn by sticking SiO2 to the surface of the steel tape. Four sets of electrolytic electrode C1, C2, C3, and C4 having the same polarity wth the confronting electrode with a preceding steel tape S therebetween but a different polarity to the adjacent electrodes are provided in a cleaning bath filled with a cleaning liquid. When the polarities of these electrodes are changed in order to prevent contamination of the electrode surface, the electrode C1, for example, is first changed from +- to 00 then to -+, then, the polarities of electrodes C2, C3, C4 are similarly changed successively, thus, decrease of electrolytic current is retarded as possible, variation of the quantity of SiO2, etc., sticking to the steel tape S is also retarded. Uniform elongation in the skin-pass rolling stage after box annealing is thus secured.

Title: Electrophoretic method for in-soil component
Inventor: SHIRATO FUSAO
IPC: B01D61/44
Filed: 1989-02-07
Abstract: PURPOSE:To improve extraction efficiency by immersing a sample into a leaching liquid added with the ion components having the higher selective adsorptivity to an ion permeable membrane than the in-soil components to be extracted and transferring the soil components into the extracting liquid which does not contain the soil components. CONSTITUTION:The ion selectivity of the ion exchange membrane eventually governs the current efficiency of a dialysis operation in the case of using this membrane as a diaphragm for electrophoresis. The extraction efficiency of the ions having small selective adsorptivity is high when the extraction efficiency with respect to the extraction time is compared with the respective ion components in the soil. The extraction rate of even the ion having a low extraction rate, iron ions, etc., is greatly improved if the ions having the large ion selectivity, lanthanum ions, etc., coexist. Namely, the incorporation of the proper ratio of the ions having the higher selective adsorptivity to the ion exchange membrane than the ions desired to be extracted contributes to the acceleration of the extraction of the ions which have the small selective adsorptivity and are desired to be extracted. The cation and anion components in the soil are easily and rapidly extracted in this way.

Abstract: PURPOSE:To reduce the surface leakage current of the title device even when the diameter of the light receiving area of the device is large so as to improve the reliability of the device by reducing the length of the outside circumference line of a P-N junction formed on the surface of an inverted area of the second conductivity type without changing the size of the area. CONSTITUTION:An N-type diffusion area 6 formed on the surface side of a window layer 4 and a re-inverted area 7 of the N-conductivity type formed on the surface side of an inverted area 5 of the P<+>-conductivity type are formed by shallowly diffusing N-type impurities, such as Te, S, Sn, Se, Si, etc., from the surface sides of the area 5 and layer 4 except the area of an electrode 10 after the area 5 is formed. A contact hole 9 is formed on the area 5 only. Thus the re-inverted area 7 of the first conductivity type is formed in the inverted area 5 of the second conductivity type and a P-N junction is formed by both of the areas having different conductivities. Therefore, the length of the outside circumference line of the P-N junction formed on the surface of the inverted area of the second conductivity type is reduced and the surface leakage current is reduced.
