Title: Base line drift correcting method
Inventor: MITO YASUTAKA
IPC: G01N30/86
Filed: 1985-03-30
Abstract: PURPOSE:To make unnecessary a large quantity of a memory capacity by preventing the necessity to store all base lines equivalent to the analyzing time. CONSTITUTION:When the base line of the chromatogram is drifted, the position of the base of the differentiating chromatogram is not zero, and shifted positively or negatively. To correct the drifting is to shift the position of the base of the differential chromatogram shown in the Fig.3 to zero and obtain the differentiating chromatogram shown in the Fig. 4. Namely, when the differentiating chromatogram shown in the Fig. 4 is obtained, the chromatogram without the draft shown in the Fig. 5 can be reproduced by integrating. To execute the correcting calculation with a real time, it is necessary to decide whether or not the base line is obtained. The formula to decide the base line is k-DELTA<dy<k+DELTA, and here, dy is a value of the differentiating chromatogram, k is the central value of the base line of the chromatogram, and DELTA is a scope (threshold) to decide the base line considering the changed part such as a nozzle.

Filed: 1984-04-06
Abstract: PURPOSE:To enable a high speed action while reventing malfunction caused by noises by controlling an address buffer for forming and outputting an internal address signal for the prescribed period and by prohibiting a fetching of an external address signal or holding the previous signal. CONSTITUTION:For the period when a word selection timing signal becomes a high level and a word line is in the selected condition by means of a comparatively high action voltage, a timing signal phi and anti phi become low and high levels, respectively. Then FETs Q3 and Q4 of an address buffer for forming an internal address signal (ai), etc., from an external address signal Ai are turned on, and a fetching of the external address signal Ai is prohibited. Simultaneously, FETs Q9 and Q10 are turned on, and outputs of FETs Q5 and Q6 for forming an invertor are positively fed back, whereby the address signal fetched previously is held. As a result, a semiconductor memory device performs a high speed action while malfunction of the address buffer caused by comparatively large power source line noises, which occur due to an action of a data output buffer, is prevented.

Title: Forming method of evaporation film
Inventor: OKADA SEIJI
IPC: H01F41/20
Filed: 1984-04-06
Abstract: PURPOSE:To improve a magnetic characteristic by a method wherein, an anomalous Hall effect is utilized, the magnetic characteristic is detected one after another and the result of detection is fed back to the condition of forming a given metal magnetic film. CONSTITUTION:An iron core 1a is inserted into a solenoid 1 for exciting a sample, so as to generate a magnetic field of 2kOe on the surfase of a substrate 2. When evaporation is conducted, a film is formed on the lower surface of the substrate 2. By disposing the solenoid 1 and the iron core to be symmetric in the vertical direction, magnetic fields at the upper and lower opposite ends of the iron core are made to be equal in magnitude and reverse in symbol to each other, and therefore a value of a symbol reverse to the one of the magnetic field generated on the upper end face turns to be the one of the magnetic field generated on the surface of the substrate. A vapor line of Gd, Fe or the like emitted from an evaporation source 4 forms a film on the substrate 2 by opening and closing a shutter 5. A base plate 17 for monitoring is disposed in the central part of a doughnut-shaped disk base plate 16, and the characteristic of a magnetic film formed on the base plate 16 is monitored by using said base plate 17 while the film is formed.

Title: Method for inspecting pattern
Inventor: UECHI MASAHITO
IPC: G03F1/84
Filed: 1989-03-20
Abstract: PURPOSE:To obviate the leakage of pattern correction by correcting even the inspection patterns at every correction of a segment pattern and visibly displaying the corrected pattern. CONSTITUTION:For example, the patterns are broken down respectively to 3 pieces of the patterns PF 1 to PF 3, PL 1 to PL 3 in such a manner that the operation to correct the pattern width of the inspection patterns and the checking of the leakage from the connections of the inter-pattern spacings can be made. The width (a) of the pattern PL 1 is corrected to a width W in the case of unifying the segment pattern width to the width W and the PF 1 is of the width W from the beginning and is, therefore, not changed by the correction. The width (b) of the pattern PL 2 and the width (c) of the PF 3 are similarly expanded respectively to the W. The spacings (e), (f) below the threshold based on the spacing D are connected in succession thereto. The corrected inspection patterns are thereafter printed and outputted.
