Inventor: TOMA KATSUMI
IPC: H01J49/26
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To solve the problems of, for example, deterioration in S/N ratio and reduction in resolution due to a data-processing problem. SOLUTION: The data-processing method consists of a step for performing the primary sampling of the signal of the ion current of a detection part, a step for dividing primarily sample data into a specific number of divided ranges, and a step for performing the secondary sampling of data from each divided range and displaying a mass spectrum. In the secondary sampling, (N)MAX is sampled in the case of (N)MAX>=(N+1)MAX and (N)MIN is sampled in the case of (N)MAX<(N+1)MAX when the maximum value of the data of the divided range is set to (N)MAX and the minimum value is set to (N)MIN, and the maximum value and the minimum value of the data in the next divided range in a direction where a mass increases or in a direction where the mass decreases are set to (N+1)MAX and (N+1)MIN, respectively.

Title: Manufacture of semiconductor device
Inventor: ONO ATSUKO
IPC: H01L29/786
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To obtain adequate mobility for a semiconductor device by calculating the rate of crystallization of a semiconductor substrate from the measurement of a light reflection factor of a semiconductor thin film, and then controlling the impurity density distribution base on the calculation result at impurity doping. SOLUTION: An amorphous silicon film 32 is formed on a substrate 31 and then becomes polycrystalline through laser annealing. Then, a gate insulating film 33 is formed from the upper of the amorphous silicon film 32, and then a gate electrode 34 is formed. The substrate 31 formed with the amorphous silicon film 32, the gate insulating film 33 and the gate electrode 34 is doped with phosphorus impurities. At that time, the state of crystallization of the substrate 31 is measured to obtain a polycrystalline silicon distribution characteristic as a reference. Then, the impurities are doped with a dose so controlled that the amorphous rate becomes, for example, 80%. After a specified lapse of time, the doped part of the substrate is irradiated with visible light to measure the reflection factor, and the state of crystallization can be understood from the measurement result.  If the amorphous rate is adequate, the doping is finished.

Title: Controlling system for stopping moving material at home position
Inventor: TENMIYOU MASAYUKI
IPC: B65G43/00
Filed: 1981-05-20
Abstract: PURPOSE:To stop a moving material at a home position in a short time with a high precision, by controlling a driving current, namely, a driving force for the moving material so that the driving force by which the moving material passes through the home position is smaller than the driving force by which the moving material approaches the home position again after overrunning the home position. CONSTITUTION:When a driving current IM is in the negative (positive) direction, a moving material 1 is moved to direction X(Y). A home position detector 6 outputs a detection signal SH which is in level ''L'' (''H'') when the moving material is off from a home position P0 in the direction Y(X). A movement direction detection signal SD is in level ''L'' (''H'') during the movement of the moving material to the direction X(Y). A driving stop circuit 10 controls the driving current IM by signals SH and SD so that the driving current IM by which the moving material approaches the point P0 after overrunning the point P0, that is, signals SH and SD are in level ''L'' or level ''H'' together is smaller than the driving current IM by which the moving material goes away from the point P0. When this control is repeated prescribed number of times, the driving stop circuit 10 stops the current IM, and the moving material stops at the point P0.

Abstract: PURPOSE:To obtain the high-grade texture approximate to a speaker unit of an aluminum die casting frame with no attachment of different part by using an aluminum clad steel plate as a frame material. CONSTITUTION:An appearance visible part 15a of a frame 15 using an aluminum clad steel plate has a state of a steel plate, and the design processing such as the spinning processing, offset printing, etc. is applied on the aluminum surface.

Filed: 1984-04-14
Abstract: PURPOSE:To take a self-diagnosis of a deterioration state speedily by impressing a voltage which is different in voltage value at least two positions of the flat part of an output current characteristic. CONSTITUTION:When 1.6V is impressed as an impressed voltage VW in normal measuring operation, an output value is a limit current value Il when a sensor operates normally.

Then, when 1.4V is impressed as an impressed voltage Va for diagnosing a part corresponding to the leftward part of the flat part 7a, various output signals are obtained according to the state of the sensor. When this output current is equal to the current value Il, it is judged that there is no deterioration, but when it is less than the current value Ia, that shows that a rising part 7a deteriorates and it is judged that the deterioration of the sensor advances.
