Title: Phase modulator
Inventor: HIRANO TAKUYA
IPC: H03C3/22
Filed: 1995-02-13
Abstract: PURPOSE: To suppress a temperature change in the phase modulator by integrating a thermister with a characteristic of compensating a change in an impedance attended with a temperature change of the phase modulator with a base band signal adjustment circuit so as to change the amplitude of a modulation signal. CONSTITUTION: An amplitude of a base band signal received from a base band signal input terminal 2 is changed by a resistor 10, a thermister 11 and a resistor 12. Let the resistance of the resistor 10, the thermister 11 and the resistor 12 be RB, RC, RT respectively, then the amplitude of a modulation signal is multiplied by RC/(RB+RC+RT). The amplitude of the modulation signal with respect to a temperature change is changed by changing the polarity of the thermister and combinations of the resistors 10, 11. That is, when the polarity of the thermister is positive (negative), it is possible to compensate phase modulation in a decreasing (increasing) direction. A change in the phase modulation due to a temperature change is minimized by utilizing the characteristic to provide an output of a stable phase modulation wave.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for producing embroidery data capable of automatically producing main axial curves and enabling the excellent radial TATAMI mat (mat made of rush for Japanese life) pattern stitch. SOLUTION: An input pattern to be embroidered is read, and a curve (main axial curve) naturally following the input pattern is produced (2). The read input pattern is converted (3) into a geodesic pattern, one of whose coordinate axes consists of the main axial curve. The geodesic pattern is swept with plural horizontal sweep traces along the other coordinate axis. Subsequently, the horizontal sweep traces are reversibly transformed (4), and stitching points in the input pattern are produced (5) according to the reversibly transformed sweep traces. The reversibly transformed sweep traces form radial sweep traces in the input pattern, and the stitching points of the radial TATAMI mat pattern stitch are produced according to the radial sweep traces. Thus, the high quality TATAMI mat pattern stitch having a beautiful radial appearance is produced.

Title: Correction of peak energy shift in auger image measurement
Inventor: SEKINE SATORU
IPC: H01J37/256
Filed: 1991-02-20
Abstract: PURPOSE:To enlarge a range where an Auger image can be normally measured by correcting a peak energy shift value to be measured corresponding to a shift amount of an analysis point from a reference point when a column-type energy analyzer is used to measure the Auger image. CONSTITUTION:An energy shift correction coefficient for displacement of an analysis point along a center axis of a column-type energy analyzer and an energy shift correction coefficient for displacement of an analysis point in a direction perpendicular to the above are obtained, and based on displacement amounts in both directions mentioned above from reference points of the respective analysis points and the obtained correction coefficients, spectroscopic energy values of the column-type energy analyzer corresponding to the respective analysis points are corrected. Therefore even if the reference points shift from the analysis points along with electron beam scanning, a peak energy value to be measured actually is prevented from shifting from a value to be measured, whereby the peak value can be always captured.

Abstract: PURPOSE:To improve breaking function by providing a metallic arc-extinguishing plate of a specified shape, between a fixed contact and a movable contact, perpendicular to the direction of the movable contact opening. CONSTITUTION:A plate-shaped metallic arc-extinguishing plate 13 sandwiched by U-shaped metallic arc-extinguishing plates 13a, is arranged between a fixed contact 8 and a movable contact 6, perpendicular to the direction that the movable contact 6 is opened. The U-shaped arc-extinguishing plate 13a is arranged with its projected end 13b directed to the space where the contact is opened. An arc 12 generated when the contact is opened is absorbed by the plate-shaped arc-extinguishing plate 13, and becomes an arc 12a, while it becomes 12b when the movable contact 6 comes to a position 6b. After the arcs 12a, 12b are formed on the U-shaped arc-extinguishing plate 13a, they are removed due to the magnetic field generated by the current that run in the arc-extinguishing plate 13a. The breaking of current can thus be carried out in a good condition.
