Title: Transmission line interface module and transmission system
Inventor: MATSUOKA HIDEKI
IPC: H04B3/32
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To eliminate the influence of a gourd potential difference and to hold transmission characteristics to high quality by short-circuiting one of the secondary-side winding terminals of a current transformer to the signal ground of a transmitting or receiving circuit and providing a parallel circuit of a resistance and a capacitor at the other terminal, and attenuating a DC current due to the ground potential difference. SOLUTION: Transmission-side and reception-side resistances 15 and 25 are inserted in series with the conductor of a coaxial line 3 and the secondary-side windings of transmission-side an reception-side current transformers 12 and 22. A DC current I1(3) of the secondary-side windings of the current transformers 12 and 22 can be suppressed more than that of the case when no resistance is provided. Even when the resistance of the conductor of the coaxial line 3 and the resistance (r) between transmission-side and reception-side ground points G1 and G2 are unknown, the sum of the resistance values R15 and R25 of the resistances 15 and 25 can be determined. Namely, the resistance (r) can suppress the DC current I1(3) even though its value is small, so that resistance values R15 and R25 are determined, assuming that the resistance value (r) is 0 to obtain a safety-side solution.  Consequently, the influence of the ground potential difference can be eliminated.

Abstract: PURPOSE:To decrease the memory capacity for the judging number of times of the sun-shadow state and solar vector and to compute the sun-shadow time quickly and accurately by obtaining the changing time of the sun-shadow state at an observing point, and computing the sum-shadow time based on the changing time. CONSTITUTION:A solar-direction-vector computing part 12 computes the solar vector at each time of an equal time interval and stores the vector into a solar-direction- vector memory means 19. The solar vector data and three-dimensional block data are read out with reading parts 13 and 14 in order to judge the sun-shadow state and imparted into a sun-shadow-state judging part 15. In the judging part 15, a half-line is made to extend along the solar-vector direction from the established observing point. When the half-line passes the three-dimensional block surface even once, the sun shadow is judged. Then the changing point of the sun-shadow state is obtained and stored into a sun-shadow-state changing-point table 16 in accordance with the magnitude of the azimuth with the established observing point as the original point. A sun-shadow-change-time computing part 17 obtains the starting and finishing times of the sun shadow based on the azimuth at the changing point. The sun-shadow time at the observing point is computed with a sun-shadow-time computing part 18.

Title: Vibration type projecting screen
Inventor: MURAKOSHI MAKOTO
IPC: G03B21/56
Filed: 1979-05-02
Abstract: PURPOSE: To obtain the image of high resolving power by so arranging the screen that the center of gravity of the system combining a rotary plate having a circular eccentric recess and a circular screen freely fitted into this eccentric recess exists at the center of revolution of the rotary plate.  
     CONSTITUTION: A number of rollers 2 are disposed to a stationary plate 1 on the same circumference and a rotary plate 3 is rotated at a high speed about the center Od by driving of a motor 5 via belt 4. This causes the screen 6 freely fitted in the circular recess 3a to make circular motion about the center OS. Since springs 7 elongate or contract slightly, the screen 6 is slightly turned by the friction with the rotary plate 3 while the rotary plate 3 is rotating. The screen 6 repeats rotation and return rotation owing to the balance between the tension and friction force of the springs 7. Where the two forces balance, the screen 6 make the circular motion alone.
