摘要： The disclosure is related to a mirror device for use particularly as a side view mirror for automobiles. Side view mirrors presently in common use comprise of plane mirrors, and are required to be of a limited size. Because of the required small size, the directional range of view such mirrors provide to the driver is quite limited, and leave out of view certain directional ranges which are important from the safety point of view. It is the purpose of this invention to enhance the directional range of view to include within the view of the driver the region on the side commonly known as the blind spot. The device of the invention makes this possible without increasing the size of the mirror, or without causing significant disadvantages. This is made possible by providing a zig-zag surface for the mirror at appropriate offset angle, so that two separate ranges of directional view which are contiguous without overlap are achieved. In a preferred mode, the mirror could comprise of a transparent sheet with appropriate surface contours, a reflector coating and a support backing.

摘要： High ionization of atoms and molecules is a requirement in several atomic and plasma studies and studies of radiation spectra, in the production of lasers and in industrial applications of various kinds. Most often, ionization of atoms is limited to the removal of the outermost electrons only, for doing which well-known techniques exist. Extraction of electrons from the core shells strongly bound to the atoms, especially the heavy atoms, is difficult. Removal of these electrons is however necessary to achieve a high level of ionization or total ionization demanded in several applications. The method of the present invention employs positron annihilation in flight as a means of eliminating the electrons of the core shells of atoms, especially in the case of elements of large atomic number, so that total or near-total ionization is possible. The method is particularly relevant in producing inner-shell ionization in plasmas and assembles of heavy ions.

摘要： A patent application is filed for an automobile side-view mirror that could avoid thousands of automobile accidents that could occur yearly on account of the well-known blind-spot hazard. The side-view mirror is a relatively low-cost item, and yet is a major contributor of automobile safety. The new device will cost substantially little more to fabricate than existing alternate devices, yet is devoid of the disadvantages inherent with the earlier devices. The new mirror is an integrated all-planar device which has no curvature and hence fully retains the distance perception of the auto driver. It provides the driver with a continuous side view of the road from close to the shoulder back toward the horizon. Contiguous images of extraneous vehicles can be seen, only one image for a given distance. Multiple reflections of light from points on the mirror are avoided. In mounting on the auto body, the new device introduces no hydrodynamical problem. It is versatile for use and esthetically appealing.

摘要： A major cause of road accidents is the well-known blind spot present within the field of view of side-view mirrors of automobiles, in particular of the left. Innovations have been made in the past and recently in designing mirrors that avoid the blind spot, and have been patented. They have some inadequacies however. This invention is based on observation of the distinct roles played by different sections of a side-view mirror. The lower section of the mirror alone accounts for view of the road region close to the auto, wherein the blind spot is located. The invention therefore presents now a modified lower section that makes viewing the blind spot region possible without introducing a curved configuration.

摘要： This disclosure relates to the production of coherent waves of electromagnetic radiation, especially of short wavelengths including X rays, in the form of pulses or continuous beams, utilizing mutually interacting beams of charged particles that include positive ions and electrons. The atoms of which the ions are formed exist in states of excitation energy by virtue of their ionization. The ions capture electrons as the two beams interact, thereby becoming capable of undergoing de-excitation and emitting characteristic electromagnetic radiation. When heavy elements and a high degree of ionization are involved, the radiation so produced can be of high frequency; often X rays. The radiation energies can be of large natural widths which make conditions favorable for the emissions to be composed into a coherent pulse or beam. Despite the extremely short life times of the excited states, the required level of population inversion of the laser medium can be achieved by a specialised approach; population inversion is generated in a limited region on the laser medium, a beam of highly positive ions, by flooding the region with electrons drawn out from an adjacent beam. The population so formed in a region is advanced along the medium, region to region, in synchronization with the progress of the coherent photons. A preferred mode of the invention that generates a coherent X ray pulse of 11.2 keV photons having an energy output of 3.6 J and a power rating 360 GW is described.
