Abstract: PURPOSE:To provide a wide band up to a DC region and a high gain by providing a feedback circuit feeding back negatively in phase part of a DC bias current of a drive output stage from a drive output stage to an inverting signal generating stage to make the bias current flowing to the drive output stage constant. CONSTITUTION:When the loop gain is sufficiently large, a bias current I3 of driver transistors (TRs) Q3a, Q3b and a bias current I4 of the output TRs Q4a, Q4b are decided nearly by Equations I, II, where VBE5a, VBE5b are base-emitter voltages of TRs Q5a, Q5b and VF4 is a forward volage of a diode D4. Thus, bias currents I3, I4 have no variance and are constant independently of a parameter of each TR. A common mode feedback loop gain AbetaCOM is expressed by Equation III, where gammae5 is each equivalent emitter resistor of the TRs Q5a, Q5b, gammaD4 is the operating resistor of the diode D4, hfe3 is each current amplification factor of the driver TRs Q3a, Q3b. As shown clearly from the Equation III, the loop gain is increased sufficiently.

Filed: 1981-08-28
Abstract: PURPOSE:To obtain a projection light close to the luminance efficiency, by inserting a cold filter and a color distribution correcting filter between a light source for projection and a target (film) through an air layer to intercept heat rays. CONSTITUTION:A cold filter 4 intercepts infrared rays having >=700nm wavelength, and a color distribution correcting filter 5 has a characteristic to transmit infrared rays of >=800nm wavelength again through as shown in a figure. Consequently, the light emitted from a light source 2 is subjected to color correction in the color distribution correcting filter 5 and illuminates a target 3 (film) with a white light having a spectral distribution close to the luminance efficiency and projects it. Most of the heat from the light source 2 is intercepted by the filter 4, and filters 4 and 5 are isolated from each other by an air layer, and therefore, conduction heat is difficult to transmit.

Title: Turbine generator
Inventor: WAKUI SHINICHI
IPC: H02K3/487
Filed: 1994-06-17
Abstract: PURPOSE:To realize significant shortening of starting time by thermally balancing respective parts of the rotor of generator at the time of starting a thyristor. CONSTITUTION:The stator 2 of a turbine generator is provided with slots 3 for inserting a field winding, a wedge 4 for holding the field winding on the pole side of the rotor 2, and a wedge 5 on the interpole side of the rotor 2. At the time of starting a thyristor, the higher harmonic magnetomotive force causing temperature rise of the rotor 2 or torque ripple forms an elliptical rotating field having long diameter on the d-axis and short diameter on the q-axis. Since higher eddy current is induced on the q-axis of the rotor 2 than on the d-axis, the radial thickness d' of the wedge 5 on the interpole side of the rotor 2 is set thicker than that (d) of the wedge 4 on the pole side thus decreasing the resistance of the wedge 5.

Abstract: PURPOSE:To perform two-dimensional correction with high accuracy and in a short time by converting the inclination of a material plane to that of a glass plate, image- forming a mark image just underneath through the glass plate, obtaining a refracted image, and correcting deviation with the one in a normal state. CONSTITUTION:When the inclination of dotted line of the glass plate 14 exists on the material plane 31 as shown in figure (c) by the correction of figure (a), and when the mark 13 of a substrate 12 is irradiated with light from a light source 11, reflected light traces the route of refraction light 23 when passing the glass plate 14. On the other hand, when the glass plate 14 is set completely in parallel with the substrate 12, the reflected light is made incident on the glass plate 14 intersecting orthogonally, therefore, it traces a route 22. Therefore, image-forming on a camera 16 goes to an image (B) shown in continuous line when the inclination exists for an image (A) shown in dotted line so shown in a display image 10 in figure (b), which generates the devia tion. A feedback correction value corresponding to the deviation is generated at an image processing part 30, and is sent to a posture control part 20, then, correction in a normal direction is performed. Thereby, posture correction performance can be improved.

Filed: 1988-06-01
Abstract: PURPOSE:To obtain a focusing state speedily by making correction information from a telephoto side to a wide side and correction information from the wide side to the telephoto side different from each other. CONSTITUTION:An evaluated value A found based upon a video signal from a photographic member 5 such as a CCD is compared with a 1st threshold value Th1 and when A>Th1, a focusing state is judged to move a rear relay (RR) lens group 4 at a normal area representative speed. When A<=Th1, on the other hand, it is judged that contrast is not sufficient and the lens is out of focus, and the RR lens group 4 is moved. Then it is judged whether a focusing signal level A is larger than a threshold value Th2 or not, and when A<Th2, an out-of-focus state is judged; when the lens is zoomed from the telephoto side to the wide side after the zooming direction is judged, a correction coefficient is set to 0.8 and the speed of the RR lens group is slowed down. When the lens is zoomed from the wide side to the telephoto side, on the other hand, the correction coefficient is set to 0.7. When A>Th2, the blur is not at an extreme level, so the correction coefficient is set to 0.9 for the zooming from the telephoto side to the wide side and to 0.8 for the zooming from the wide side to the telephoto side.
