Abstract: PURPOSE:To make bearing calculation and demodulation possible and make circuit constitution simple by performing the frequency analysis by complex inputs in the band centering at the frequency conversion signal near the carrier frequency. CONSTITUTION:The signal f1' of the same conversion frequency omega' as carrier frequency omega and the signal f2' of a 90 deg. phase difference therefrom are generated by a frequency conversion signal generating circuit 2', and the multiplying of the signal (c) from the sensor and the conversion signals f1', f2' is accomplished in a multiplier 7, whereby the demodulation signals g1' and g2' are obtained. When these signals are applied to a frequency analyzing part 8, the real number signal ma1' and imaginary number signal mb1', the real number signal ma2' and imaginary number signal mb2' are obtained. These signals are applied to a bearing calculating part 10. In the part 10, the differential frequency DELTAomega between the carrier frequency omega and the conversion frequency omega' and a phase error psi' are obtained, based on which the bearing is calculated.

Title: Automatic fine regulation system for mass analytic magnetic field in case of ion implantation device
Inventor: TSUNENARI KINJI
IPC: H01J37/20
Filed: 1982-04-12
Abstract: PURPOSE:To make the peak of beam strength findable in a speedy manner without any scanning of an analytic magnetic field so as to aim at the promptitude of regulation, by installing a coule of electrostatic deflecting plates in an interspace between an analyzer magnet and an nalyzer slit. CONSTITUTION:During beam lining, a couple of electrostatic deflecting plates 5 are installed in an interspace between an analyzer magnet 2 and a slit 3 while an AC signal from an oscillator 6 is impressed on these plates 5 and thereby an ion beam 1 is slightly oscillated in the same inner surface as being deflected by the analyzer magnet 2. At this time, the value of a current flowing into a target 4 is phase-detected by a phase wave detector 7 by regarding the AC signal from the oscillator 6 as a reference signal whereby, before the AC signal is impressed on these deflecting plates 5, that is, when the ion beam 1 is not yet deflected by these deflecting plates 5, an error signal (e) proportioned to a positional slippage in the beam 1 in relation to the central part of the slit 3 is secured at an output port 8. Using this error signal (e), an analyzer magnet power source 9 is conducted with negative feedback whereby an analytic magnetic field is minutely regulated so as to get the peak value of a beam current.

IPC: G02F1/313
Filed: 1995-03-20
Abstract: PURPOSE: To obtain a nonlinear optical device which is allowed to operate with low power by utilizing an optical circulator having asymmetrical optical path lengths. CONSTITUTION: The signal light rays divided in respective polarization directions are passed through Faraday rotators 84, 85 and half-wave plates 87, 88 and are synthesized by a polarization beam splitter 83 when signal pulses 81 are made incident on a polarization beam splitter 82 by matching the polarization with a direction 818 forming an angle of 45 deg. with the axis of this polarization beam splitter 82 such a manner that the signal pulses 81 are divided to the orthogonal polarized waves of the same intensity. Here, the optical path lengths in which the respective light pulses pass vary and, therefore, the two signal pulses having the orthogonal polarized waves parting by the time interval corresponding to the optical path length difference are obtd.  The demultiplexed two signal pulses pass again the Faraday rotator 86 and the half-wave plate 89 and are rotated in polarization by 45 deg. while the relation orthogonal with each other is maintained. The light pulses are thereafter multiplexed with a control light pulse 810 by a multiplexer 811 and are made incident on the nonlinear optical medium 812.

Title: Transferring apparatus of mask pattern onto wafer

IPC: G03F7/20
Filed: 1989-03-15
Abstract: PURPOSE:To enable accurate transfer of a minute pattern formed on a mask onto a wafer by controlling a heat wave-emitting device to turn OFF when a soft X-ray generating device is ON while controlling said heat-wave emitting device to turn ON when the soft X-ray generating device is OFF. CONSTITUTION:An incandescent lamp of a heat-wave emitting device 15 is turned OFF when a pattern formed on a mask 3 is transferred by exposure onto a wafer 4 by opening a shutter of a soft X-ray generating device 1, while said lamp is turned ON when the shutter is closed. Moreover, an electric power supplied to the incandescent lamp is adjusted so that the energy of a soft X-ray from the soft X-ray generating device 1 and the energy of a heat wave from the heat-wave emitting device 15 become equal. Accordingly, the energy emitted to the mask 3 is not varied either in exposure or during stoppage of the exposure, and therefore a rise in temperature of the mask 3 is saturated easily and turns invariable. Thereby the deformation of the mask 3 due to a change in the temperature of the mask 3 is prevented and an error in alignment of position of the mask 3 is eliminated.

Abstract: PURPOSE:To improve reliability by investigating the frequency change of a reproduction signal and compensating an expected sample value when the frequency is high. CONSTITUTION:A weighting circuit 50 which is connected to a bus selector 40, a bus memory 30 and an Add Compare Selector (an ACS) 20 is provided. Then, it arithmetically operates a gain compensation signal (h) for executing weighting on the expected value of the ACS 20 based on the output (g) of the bus selector 40 and the value (f) of the memory 30 and sends it to the ACS 20. The weighting of the expected value is executed so as to raise the gain of the ACS 20 when the frequency of a demodulation signal is high. The number of output data '1' in the bus memory 31 of an m bits which is one of the memory 30 and the number of '1' among the output data of the selector 40 of an n bits are added by adders 51 and 53 in the circuit 50 and inputted to a multiplier 54. Then, a signal (h) is obtained by multiplying it by a constant K which is adjusted based on the bit numbers (m) and (n) of reference data and the gain of an AGC circuit 5. Thus, since the precise expected value can be obtained by the signal (h), the reliability is improved.
