Abstract: It is the objective of the present invention to resolve the limitations on transmission capacity and distance in a system by means of a simple design, through the provision of a means for restraining the deterioration in transmission characteristics that is the result of accumulation over the entire system of third order dispersion in the optical fiber. In the present invention, there is provided an optical fiber transmission path in which positive dispersion fibers 40,46,52,and 54 and negative dispersion fibers 42,48 (referred to as optical fibers hereinafter), which have at least second and third order dispersion of mutually opposite signs, are combined. In addition, the optical fiber is disposed so that the average third order dispersion value on the transmission path overall is reduced, and so the length of each optical fiber is sufficiently smaller than the square root of the product of the second order dispersion length, which is determined from the second order dispersion value of the optical fiber and the pulse width of the signal, and the non-linear length, which is determined from the average power of the signal within the optical fiber and the optical fiber nonlinear coefficient.

Abstract: A machine for brewing tea, particularly in a shop situation. The machine has a housing and at least one brewing assembly. The brewing assembly is formed to hold a brewing cup that has a filter that defines and separates a first cavity within the brewing cup for containing tea leaves and a second cavity from which tea leaves are excluded. The housing has a water supply that supplies a predetermined volume of water at a temperature that is suitable for infusing tea leaves. It also has a water supply channel for delivering the water into the first cavity of the brewing cup, and a siphon tube that has a siphoning end that extends orthogonally upward into the second cavity of the brewing cup and a downward projecting dispensing end. The apparatus is constructed in a way that tea leaves infuse as the water is supplied into the first cavity of the brewing cup, but once the level of infused tea liquor in the second cavity of the brewing cup rises above the siphoning end of the siphon tube the tea liquor siphons down the siphon tube and is dispensed from the dispensing end of the siphon tube.

Abstract: The invention makes possible to increase the degree of radiation focusing by the lens, to use particles of higher energies, and to increase the coefficients, depending on these factors, of the devices, the lens is used in. Thus the sublens (18) of the least degree of integration represents a package of the channels (5), which is growing ou t of joint drawing and forming the capillaries, which are laid in a bundle. The sublens es of each higher degree of integration represents a package of sublenses of the previo us degree of integration, which is growing out of their joint drawing and forming. The sublenses are growing out of performing the said operations at the pressure of the gaseous medium inside the channels being higher than the pressure in the space between the sublenses of the previous degree of integration and at the temperature of their material softening and splicing the walls. To produce the lenses a bundle of stocks (capillaries) i n a tubular envelope is fed to the furnace (at the first stage) or stocks, produced on t he previous degree, and the bundle is drawing from the furnace at the speed, exceeding t he speed of feeding. The product is cut off on stocks for the next stage, and at the fin al stage the product is formed by varying the drawing speed, after what the parts with formed barrel-shaped thickenings are cut of.

Title: Processing for sonic waveforms
Inventor: BLANCH JOAKIM O
IPC: G01V1/48
Filed: 2000-04-12
Granted: 2006-08-29
Abstract: A method (Fig. 1) for creating a frequency or time domain semblance for use in conjunction with acoustic logging tools (100, 130, 140, 145). The frequency domain semblance (Fig. 2F) may be obtained by transforming an acoustic signal (150) received at multiple depths into the frequency domain, combining the received waveforms corresponding to the different depths, and expressing the result in a graph with slowness and frequency axes. Another aspect of the invention is the treatment of two or more time domain semblances (Fig. 2B) as probability density functions of the slowness for an acoustic signal. This enables the combination of time domain semblances from the same depth in the wellbore. Once combined the time domain semblances more accurately depict the slowness of an acoustic wave through the formation at the selected depth. In addition, a related self-adaptation method to compress the waveform data downhole for storage or transmission is also disclosed.
