Title: Ripple filter circuit
Inventor: FUJISAWA MASANORI
IPC: H02J3/01
Filed: 1990-07-31
Abstract: PURPOSE:To prevent the influence of a fluctuation from appearing in a ripple filter by providing a comparator for comparing the output voltage of a ripple filter circuit and a power supply voltage, and controlling a third transistor in the cut-off direction by the output signal of the comparator circuit at the time when the power supply voltage is dropped. CONSTITUTION:When a power supply voltage VCC is dropped, the base of a transistor Tr8 is also dropped in a certain ratio (R6/(R6+R7)). However, since a comparator part A2 is added, as for the base potentials of transistors Tr7, Tr8, when the voltage VCC of a current line is changed downward suddenly, the base potential of Tr7 becomes higher than the base potential of Tr8. Therefore, Tr7 is turned on, and also, Tr6 is turned on. Thus, since Tr3 is in the turn-off direction, it becomes a high impedance, and it can be prevented that a ripple is mixed in from the power source line VCC. Accordingly, even if the power supply voltage of the power source line is fluctuated suddenly, the fluctuation of the power source line does not appear in the ripple filter output.

Filed: 1995-08-09
Abstract: PURPOSE: To easily and quickly obtain the best focusing position for an alignment sensor and measurement values at its position by finding out a Z coordinate when the detection signal width becomes the minimum while an ISS reference mark is scanned in an X direction against the ISS mark on a reticle. CONSTITUTION: A control means scans the projected image of an ISS reference mark 43X against a reticle in an X direction, crossing an ISS reticle mark 11X on the side of a reticle 10. Then, when a Z coordinate of a reference pattern plate exceeds Zo +ΔZ, the relation of a detection signal width against the Z coordinate in the reference pattern plate is approximized by a quadratic curve according to a least square in order to obtain the Z coordinate when its signal width becomes the minimum as an actual best focusing position. Further, the marking position at the actual best focusing position is judged to be a position of the mark 11X in an X direction on the reticle 10.

Abstract: PURPOSE:To allow correct temp. measurement even in the process of oxidation of a material to be measured of fluctuating emissivities by making temp. measurement in accordance with the max. output among the outputs corresponding to the wavelengths of detectors with a measuring means. CONSTITUTION:The measuring means 7 decides, computes and outputs the signal for the wavelength to provide the max. output with which the emissivity is nearly 1 and which is high in indicated value and is approximate to the true temp. among the outputs of the detectors 41, 42 with respect to the plural wavelengths separated by a separating means 3, such as rotating sector as a temp. signal. The correct temp. measurement is possible even in the process of the oxidation of the material to be measured by such multiwavelength measurement. The measurement is first carried out on the short wavelength side and the measuring wavelength is successively switched to the long wavelength side and the measurement is made when the indication on the short wavelength side comes to change even if the indication on the long wavelength side by the growth of the oxide film is slightly low and remains stable. The stable temp. measurement in the process of the oxidation of a steel sheet, etc., is then executed.

Abstract: PROBLEM TO BE SOLVED: To obtain stable rotation driving and rotation stopping motion in spite of simple constitution at the time of change-over display of a rotary display body by providing a permanent magnet which attracts and holds the rotary display body at two positions in a rotation direction. SOLUTION: The permanent magnet 28 force insert and fits an annular magnet part 28c in a display drum to be integrated and the display drum integrally rotates with rotation of the permanent magnet 28 rotating around an iron core 25. In the display drum, respective display contents are recorded at two display positions having 180 deg. difference on an outer peripheral surface thereof and the permanent magnet 28 decides two rotation stopping positions corresponding to the display positions. Accordingly the display drum can be attracted and held at either one among two positions in the rotation direction and changing-over of the display positions of the display drum can be attained only by 180 deg. rotation to one among two positions where the permanent magnet 28 attracts.  Since attracting action of the permanent magnet 28 is exerted at the rotation stopping positions, display position of the display drum can be changed-over even by manual operation.
