Forming a plurality of loops in an optical fiber around a spool adjacent to an exposed end face can suppress internal reflections from the exposed end face. The radius of the loops can attenuate light that is propagating to and from the end face by causing light to leak out of the optical fiber's core and into its cladding. The radius can be selected to control physical stress in the optical fiber and promote reliability. The radius and the number of loops can be selected to meet a return loss specification. The loops can be formed by coiling the optical fiber around a spool that includes a slot for holding the optical fiber until it is put into service.

A technique that can realize high integration even for multilayered three-dimensional structures at low costs by improving the performance of the semiconductor device having recording or switching functions by employing a device structure that enables high precision controlling of the movement of ions in the solid electrolyte. The semiconductor element of the device is formed as follows; two or more layers are deposited with different components respectively between a pair of electrodes disposed separately in the vertical (z-axis) direction, then a pulse voltage is applied between those electrodes to form a conductive path. The resistance value of the path changes according to an information signal. Furthermore, a region is formed at a middle part of the conductive path. The region is used to accumulate a component that improves the conductivity of the path, thereby enabling the resistance value (rate) to response currently to the information signal. More preferably, an electrode should also be formed at least in either the x-axis or y-axis direction to apply a control voltage to the electrode.

A method of manufacturing monolithic glass reflectors for concentrating sunlight in a solar energy system is disclosed. The method of manufacturing allows large monolithic glass reflectors to be made from float glass in order to realize significant cost savings on the total system cost for a solar energy system. The method of manufacture includes steps of heating a sheet of float glass positioned over a concave mold until the sheet of glass sags and stretches to conform to the shape of the mold. The edges of the dish-shaped glass are rolled for structural stiffening around the periphery. The dish-shaped glass is then silvered to create a dish-shaped mirror that reflects solar radiation to a focus. The surface of the mold that contacts the float glass preferably has a grooved surface profile comprising a plurality of cusps and concave valleys. This grooved profile minimizes the contact area and marring of the specular glass surface, reduces parasitic heat transfer into the mold and increases mold lifetime. The disclosed method of manufacture is capable of high production rates sufficiently fast to accommodate the output of a conventional float glass production line so that monolithic glass reflectors can be produced as quickly as a float glass production can make sheets of float glass to be used in the process.

This invention generally relates to an elevated transportation network run on electricity with personalized cars that can automatically transport passengers anywhere in a large city or densely populated metropolitan area served by the system without stopping on the way to the final destination. The cars travel on two continuous concrete ribbons with no bumps or cutouts crossing the tire path during switching or on the straight away. The travel path is a combination of central routing and individual car communications with car automatic steering and distance control. The personalized transportation concept can also apply to high speed intercity transportation allowing instant available transportation without intermediate time consuming stops.
