IPC: H03M1/00
Filed: 1991-03-22
Abstract: PURPOSE: To attain stabilization without additional costs by generating a terminating impedance by parallelly connecting a resistor to the input terminal of a digital filter or a subtracter. CONSTITUTION: A digital filter L8 is connected after a sampling rate reducing device 6 and its transmission function is adjustable for generating the terminating impedance to a two-wire type transmission line 1. At such a time, the terminating impedance is generated by parallelly connecting a resistor 13 to the input terminal of a filter 8 or a subtracter 9. Besides, the input terminal of an adder 7 is connected to a two-wire type transmission line 2 and a reception line 3, and its output terminal is guided to one input terminal of the subtracter 9. Then, the other input terminal of the subtracter 9 is connected to the output terminal of the reducing device 6 and the output signal of the adder 7 is subtracted from the output signal of the reducing device 6. The output of the subtracter 9 is fed back through an impedance 15 to the filter 8 and the subtracter 9.  Then, over control is suppressed by the resistor 13 and stabilization is possible without requiring additional costs.

Title: Mechanism for detecting focus of reduction stepper
Inventor: TAKAHASHI SHOJI
IPC: G03F7/207
Filed: 1992-03-04
Abstract: PURPOSE:To accurately position a substrate to which a pattern is to be transferred to the focusing position of a reduction-projection lens even when the focusing position of the lens changes. CONSTITUTION:A light source 20, first slit 22, and second slit 24 are arranged on the opposite side of a substrate 28 to which a pattern is to be transferred with respect to a reduction-projection lens 2 and interference light from the second slit 24 is projected upon the substrate through part of the lens 2. The interference fringes projected upon the substrate 28 are reflected by a half mirror 30 after the fringes again pass through part of the lens 2 and received by means of a CCD 32. Since the pattern interval detected by means of the CCD 32 is proportional to the distance from the slit 24 to the substrate 28, the substrate 28 can be positioned so that the surface of the substrate 28 can come to the focusing position of the lens 2 from the pattern interval detected by means of the CCD 32 at the time of performing exposure in a succeeding stage when the pattern interval of the interference fringes is detected while the surface of the substrate 28 is positioned to the focusing position of the lens 2 and the detected interval is set as a reference value in advance.

Abstract: PURPOSE:To increase the recording and reproducing efficiency by forming a layer of a nonmagnetic body on a substrate of a magnetic body with high magnetic permeability and by formng a continuous film of a magnetic body with high magnetic permeability on part of the interface and in the nonmagetic layer. CONSTITUTION:In a main magnetic pole, layers 13, 15 of a nonmagnetic body such as SiO2, Al2O3, Au or Cu are formed on a substrate 12 of a magnetic body with high magnetic permeability such as Mn-Zn ferrite or Ni-Zn ferrite, and a film 14 of a manetic body with high magnetic permeability such as an Ni-Fe alloy or a Co-Zr alloy is formed on part of the interface between the substrate 12 and the layer 13 and in the layer 13 so that it is exposed to the surface of the layer 13 by a width W. Since the magntic body 12 is positioned very close to an auxiliary magnetic pole at an interval of several mum order from the surface facing a medium, the film 14 leads efficiently magnetic flux generated by magnetization with the auxiliary magnetic pole during recording and magnetic flux generated by the recording magnetization of the medium during reproduction, and the magnetic bond of the auxiliary magnetic pole to the main magnetic pole is strengthened, so the recording and reproducing efficiency can be increased.

Abstract: PURPOSE:To more accurately calculate the creep speed of a UO2 pellet by changing and adjusting creep behavior by changing the crystal particle shape of a fuel crystal particle. CONSTITUTION:After a UO2 pellet whose crystal particles have no regular polygonal shape but a total phase having a recessed surface is prepared, a high temp. creep test is applied to the pellet under a condition of 1400 deg.C and 45 MPa and, when creep speed (v1) after the correction of density, v1=3X10<-3>/Hr is obtained. When the creep speed of an UO2 pellet having a separate crystal shape is experimentally calculated under the same condition, this speed v2 becomes 1X10<-3>/Hr. Whereas, in the calculation from a total phase structure, average peripheral length is 1.5 times the peripheral length calculated from an equivalent circle area diameter, that is, n=1.5 and the pellet is n=1.0 and, when the creep speed v1 is considered on the basis of the creep speed v2, v1/v2=3.2 is formed and v1 is about 3 times of v2.

Filed: 1992-03-06
Abstract: PURPOSE:To draw a prescribed number of ions through a slit by chopping invertedly a deflection direction of micro-ion beam against a slit instantly by means of a deflecting plane and a field control circuit. CONSTITUTION:An ion beam is made to deflect by biasing a deflecting plate 3. Then the beam is cut off by a micro-slit 8. Polarity of the bias applied to the deflecting plate 3 is instantly switched by a beam chopper circuit 16. The beam is deflected in the reverse direction to be cut off by the micro-slit 8 again, however, a very small amount of ions pass through the slit 8 in the moment of passing through the aperture in the center. Number of the secondary ions coming out from the target is measured to estimate the number of radiation ion. When no ion is emitted at one inversion, inversion and measurement of deflection are repeated because probability of passing-through is low.
