A tube has been developed in which the shapes of streams of charged particles moving in the earth's magnetic field can be produced accurately to scale. The tube has been named the Störmertron in honor of Carl Störmer who calculated many such orbits. New developments which have made this tube possible include a method for coating the inside of large glass tubes with a transparent electrically conducting film, and an electron gun producing gas-focused streams in less than ½ micron of mercury vapor, a nearly vapor-free grease joint, and a nearly vapor-free carbon black. The magnetic dipole field of the earth is simulated with an Alnico magnet capped with properly shaped soft iron caps. The stream is deflected using two pairs of yoke coils near the gun.

Based on thoughts of ship safety, one novel scheme of ship mooring remote measurement & control system is proposed, including information obtaining subsystem and remote control subsystem. The former is to detect mooring system’s environmental parameters such as wind speed, water speed, and anchor chain stress, then to submit such parameters to remote control center by wireless channel more than 2.4 GHz. The latter ‘s main body is the aforementioned remote control center and it’s based on an embedded WEB server with functions such as calculating probability of mooring movement, emitting alarming signal, etc. Except an ocean water speed detector invented by ourselves, the hardware design in this paper is based on IC (integrated chip).

In order to fully exploit the Shuttle orbiter's payload delivery and retrieval capabilities and to provide on-orbit servicing of other spacecraft systems, a remotely piloted free-flyer will be an essential element of the developing space transportation system. Not only will a free-flying system be able to deliver payloads to a significantly higher orbit than can the Shuttle, it will be able to retrieve satellites from their operational orbit and return them to the orbiter or the earth for servicing. Ultimately, the free-flyer can be used in the construction of large space systems that exceed a single Shuttle launch capability. Following completion of its mission, the free-flyer can return to the earth, or it can remain in orbit for storage between Shuttle missions to eliminate relaunch expenses. The free-flyer may be controlled from either the aft flight deck or a ground based station. Remote control from a ground based station has distinct advantages because it will eliminate all requirements imposed on the Shuttle for aft flight deck and cargo bay flight support equipment and interfaces.

Using the force of thought to control the earth might appear like a thing removed from sci-fi books. Be that as it may, the advancements we see today were once sci-fi beginning from man arriving on the moon to examine in teleportation. Thus controlling the surroundings through musings is likewise one of the apexes of that development called Brain Computer Interface. Utilizing cerebrum waves measured of an EEG to control PC. The contemporary remote control is supplanted by the force of one's idea which couldturn considerations into reality. The application ranges from utilizing contemplations to play diversions to re-wiring of the brain.The numerous unending potential outcomes extrapolated from this innovation could be of Controlling prosthetic appendages, robots, PC and practicing the cerebrum to rewire itself in stroke patients. The thought of this is basic, utilizing the typical EEG estimation that distinguishes the electrical yield of the cerebrum and utilizing them as a data to different gadgets As no persons contemplations are same; this framework gives distinction to the one utilizing it. Deadened patients who can't utilize their appendages and persons experiencing 'secured disorder' whose cerebrum action are all the same can connect utilizing this kind of non intrusive BCI. This paper is a tricky study that considers in the domain of this advancement distinguishing both its advantages and disadvantages as it prompts another time of savvy advances for what's to come.

A newly developed conical anode field emission electron gun (FE-GUN)has been installed on the JSM-840F Scanning Electron Microscope (SEM). The cross sectional view of the column is shown in Fig. 1. The gun is usable at a wide accelerating voltage range from 0.5 kV to 40 kV, and is suitable for general purpose SEMs. The gun can be used within the virtual source range even at an extract voltage as high as 7 kV and an accelerating voltage as low as 0.5 kV. The extract voltage can be raised up to 7 kV even when the emitter tip radius becomes larger after repeated flashing for smoothing the emitter tip surface. This allows elongation of the emitter life.With the FE-GUN, since the electron source (virtual source) moves with accelerating voltage change, an image may disappear due to the deviation of the electron probe from the optical axis when the accelerating voltage is changed.

AbstractThe 50th anniversary of the application of electron probe microanalysis (EPMA) to the Earth Sciences provides an opportunity for an assessment of the state-of-the-art of the technique. Stemming from the introduction of the first automated instruments, the latest developments of EPMA and some typical applications are reviewed with an eye to the future. The most noticeable recent technical achievements such as the field-emission electron gun, the latest generation of energy and wavelength dispersive spectrometers, and the development of analytical methods based on new sets of first principle data obtained by the use of sophisticated computer codes, allow for the extension of the method to the analysis of trace elements, ultra-light elements (down to Li), small particles, and thin films, with a high degree of accuracy and precision and within a considerably reduced volume of interaction. A number of working examples and a thorough list of references provide the reader with a working knowledge of the capabilities and limitations of EPMA today.

The Mean

The motion of an artificial satellite around the Moon is much more complicated than that around the Earth, since the shape of the Moon is a triaxial ellipsoid and the effect of the Earth on the motion is very important even for a very close satellite.The differential equations of motion of the satellite are written in canonical form of three degrees of freedom with time depending Hamiltonian. By eliminating short-periodic terms depending on the mean longitude of the satellite and by assuming that the Earth is moving on the lunar equator, however, the equations are reduced to those of two degrees of freedom with an energy integral.Since the mean motion of the Earth around the Moon is more rapid than the secular motion of the argument of pericentre of the satellite by a factor of one order, the terms depending on the longitude of the Earth can be eliminated, and the degree of freedom is reduced to one.Then the motion can be discussed by drawing equi-energy curves in two-dimensional space. According to these figures satellites with high inclination have large possibilities of falling down to the lunar surface even if the initial eccentricities are very small.The principal properties of the motion are not changed even if plausible values ofJ3andJ4of the Moon are included.This paper has been published in Publ. astr. Soc.Japan15, 301, 1963.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.
