Patent JP-H07280586-A (JP)
Title: Signal processing method for detecting signal
Inventor: OKAZAKI YUKIYOSHI
IPC: G01N27/90
Filed: 1994-04-05
Abstract: PURPOSE:To improve a detecting accuracy even when a signal which is not similar to a signal to be detected and employed for designing a filter is processed by filtering a detection signal and processing the obtained output signal by specified equations. CONSTITUTION:A signal detected from a material 1 to be inspected by an eddy current detector 2 is frequency-converted by a frequency converter 3. F(omega)XS*(-omega) is calculated by a calculator 4, and time-converted by a time converter 9. Filters 10-12 sequentially process its output Z(t) by equations I, II, III and sequentially supply it to input terminals IN1-IN3 of a selector 14. An operator displays a desired signal of output signals of the filters on a display 15, and designates it to a discriminator 13 to vary values epsilon of the respective filters to reduce noise to a desired level. That is, when the signal to be detected is similar to the signal detected by the detector 2, if the output signal is selected, a signal in which the noise is removed is displayed. When it is not similar, an output signal in which noises in the signals 11, 12 are more removed is selected, and displayed. The noise can be further reduced by altering the values epsilonof the respective filters.

Title: Formation of single crystal film
Inventor: KOBAYASHI TOSHIO
IPC: C30B1/08
Filed: 1984-05-09
Abstract: PURPOSE:To produce a single crystal film having large area in the solid-phase lateral epitaxial growth, by carrying out the epitaxial growth while converting the material amorphous just before the front part of the crystal growth. CONSTITUTION:An SiO2 film 12 having an opening 13 and an amorphous Si film 14 are applied to an Si single crystal substrate 11, and a mask 16 is placed thereon aligning the opening 17 of the mask 16 to the opening 13 of the SiO2 film. The substrate temperature is maintained at about 800 deg.C, and the mask is transferred along the direction of the arrow at a prescribed speed while implanting Si<+> ion to the amorphous Si film through the opening 17 to transform the amorphous Si film 14 to a single crystal Si film 15. When the temperature of the substrate 11 becomes sufficiently high, the amorphous Si of the film 14 is transformed to the single crystal Si film 15 at the part contacting with the opening 13, and the amorphous Si becomes polycrystalline Si film 20 at the part separated from the opening 13. The polycrystalline Si film is turned gradually to the amorphous Si film 19 by the bombardment of Si<+> ion. Accordingly, the amorphous Si film can be converted easily to the single crystal Si film 15 by epitaxial growth.

Title: Position detecting circuit
Inventor: JIYONASAN EI BAANII
IPC: G01D5/14
Filed: 1989-04-11
Abstract: PURPOSE: To vary the time constant of circuit stepwise under a state where the resistance and wiper position are accurate and reproducible by moving the wiper of a potentiometer along resistor elements, i.e., two segments, while touching thereby bridging the gap between both segments. CONSTITUTION: At position D of relay contacts 548, 602, power to a load 23 depends on the position of a wiper 108 along a segment 102. Since the wiper 108 moves toward the gap between segments 102, 104, resistance of the circuit increases to cause increase of time constant thus minimizing the power to the load 23. When the wiper 108 arrives at the gap and touches both segments 102, 104, capacitance of a capacitor 120 is added to the circuit to increase the time constant steeply and thereby the load is turned off. The relay contacts 548, 602 are shifted from position D to C through instantaneous closing of any one of remote switches 516-522 and the power to the load can be controlled by the resistance of a resistor 604.

Title: Electronic lens
Inventor: YANAGIDA TAKEHIKO
IPC: H01J37/141
Filed: 1990-04-06
Abstract: PURPOSE:To minimize drift by forming a vacuum space with whole face of an exciting coil and a magnetic path. CONSTITUTION:Although an exciting coil 3 is cooled by cooling water, the temperatures of a coil bobbin 4 and the outer periphery of the coil 3 rise because of a great heating value of the coil 3. However, a space 15 exists on the outside of the bobbin 4 and the outer periphery of the coil 3 and is kept in vacuum, and so only small heat is transfered from the bobbin 4 and the outer periphery of the coil 3 to an upper magnetic path 1 and a lower magnetic path 2. Specially, the space 15 between the outer periphery of the coil 3 and the inside of the magnetic path 1 is very narrow but kept in vacuum, to keep the amount of heat transfer from the outer periphery of the coil 3 to the inside of the magnetic path 1 to a minimum. It is thus possible to restrain the temperature of a sample board 10 mounted on the upper magnetic path 1 from rising and reduce drift.
