    摘要: In order to establish the communication lines among the movable bodies and/or fixed stations and to configure communication system with a small number of satellites, present method has the steps of determining six orbit-related parameters by using a input conditions including a geographical condition of the service area, a desired service time and the tolerance of an ascending vertical angle within which the satellite can be viewed from the service area, and establishing the satellite communication with one or more satellites, an individual satellite being arranged on the orbits selected and combined among plural elliptical orbits corresponding to the determined six orbit-related parameters on which the satellites stay for a sufficiently long time that they may come successfully into sight in the zenith direction.

    摘要: A gas-liquid separation method for electroconductive gas-liquid two phase flow and the device therefor wherein electrodes are disposed in the vicinity of inlet and outlet portions of the gas-liquid separation region in the flow passage of electroconductive gas-liquid two phase flow so as to flow an electric current thereto. A magnet is disposed in the gas-liquid separation region of the flow passage so as to generate a magnetic field perpendicular to the current and to generate an electromagnetic force acting along the flow passage wall on the electroconductive liquid by taking advantage of the Flemming's left hand law, thereby separating the electroconductive gas-liquid two phase flow into gas phase and liquid phase. A hydrophobic porous material having water permeability is employed as the flow passage wall in the gas-liquid separation region; the gas-liquid separation region is disposed in a reduced pressure region; and the separated gas phase is effectively removed out of the flow passage.

    摘要: An earth observation system capable of observing the earth globally and uniformly in a steady observation operation mode while observing a given district on the earth in a high-frequency observation operation mode, as occasion requires, includes a plurality of observation satellites each equipped with an orbit transfer facility, an observation data receiving system, an observation satellite operating ground system, an observation command facility such as anti-disaster task forces, institutes or the like. In the steady observation operation mode for observing globally the earth, M observation satellites are constellated on each of L sun-synchronized quasi-recurrent orbits each having a same altitude and a same inclination (where L and M represents natural numbers). In the high-frequency observation operation mode for observing a particular district on the earth, M satellites are constellated on each of L sun-synchronized recurrent orbits each having a nominal altitude of 561 km and a nominal inclination 97.6 degrees or alternatively a nominal altitude of 888.3 km and a nominal inclination of 98.8 degrees.

    摘要: An electronic stereoscopic viewing device has an electronic signal generator which is coupled electronically to a liquid crystal display screen. The display screen upon receipt of a signal from the signal generator displays first and second views of an image with the first and second images being parallactically displaced with respect to one another. A first optical pathway conducts the first parallactically displaced view to a left eye viewing port and a second optical pathway conducts the second parallactically displaced view to a right eye viewing port. The optical pathways between the display screen and the left and right eye viewing ports are such that the first and second images are conducted to the respective left and right eye viewing ports in a manner maintaining the integrity of each such that the individually parallactically displaced first and second views of the images are received at the respective left and right eye viewing ports without contamination of one by the other.

    摘要: An electronic tennis game having a display panel with ball segments which are illuminated in different sequences to simulate a tennis ball which can move from one side of the tennis court to the other along different trajectories. Player elements are provided on each side of the display panel at positions which intercept the trajectories, each player element including a body portion and racket segments which can be sequentially illuminated to simulate a tennis player swinging his racket. Corresponding to each player element is a return button. A game operator attempts to ascertain the trajectory of an approaching ball and depress the return button corresponding to a player element positioned to intercept it. If the return button is depressed at the right time, the sequentially illuminated racket segments of the selected player element appear to hit the ball back to the other side of the tennis court.

    摘要: A simulated baseball game can be constructed so as to utilize a simulated baseball tethered on an arm in such a manner that the ball can be rotated across a simulated baseball playing field. The arm is mounted on a pylon by a universal joint so that it can be rotated generally between the field area of the playing field and the home plate of the playing field. A spring-loaded, latch-controlled propulsion member mounted generally in the field area of the playing field is used to hit the ball so as to cause it to rotate from an at rest position in the field area of the playing field toward and across the home plate of the playing field. A simulated bat may be actuated during such movement of the ball in an effort to hit the ball toward any one of a plurality of targets located in the field area. A base hit or a home run is indicated by the ball hitting a target labeled so as to correspond to such a hit or a home run. A strike is indicated by the simulated bat having been actuated without hitting the ball or by the ball hitting against a designated area in back of the home plate area of the playing field. A ball is designated by the simulated baseball moving past the home plate area of the playing field without being hit and without the ball hitting this designated area.
