A floor working machine includes a U-turn control unit for causing a self-propelled vehicle body to make a U-turn automatically to adjust the workingimplement to a work line adjacent a work line treated before the U-turn, a spin turn control unit for causing the self-propelled vehicle body to make a spin turn automatically to adjust the working implement to a work line adjacent a work line treated...

A method and apparatus is disclosed for suppressing microphonic noise in proportional counter neutron detection in borehole logging-while-drilling measurements. Noise is reduced by (1) applying the outputs of two detectors respectively to positive and negative inputs of a differential amplifier; (2) generating output pulses by applying the output of the differential amplifier to positive and negat...

A downhole production instrumentation comprising a modular tool used in the acquisition and control of information, and actuation of electromechanical devices in a production well is presented. The tool is suitable for both permanent and retrievable applications for measurement of production fluid and geological formation parameters. Multi well/multizone monitoring and control can also be provided...

A tire tread that is applicable to retread a worn tire carcass. The tire tread includes a cured tread portion having a first shoulder and a second shoulder. A first uncured wing portion extends from the first shoulder and a second uncured wing portion extends from the second shoulder. Further, an end section at each end of the tire tread portion is uncured. When the tire tread is wrapped around th...

A method and apparatus for processing a character for anti-aliased display on a raster output device. A set of density values is computed for a set of raster positions to represent the character and the density values of the set are scaled to extend their range upward toward a maximum density value, whereby generally at least one of the density values of the set becomes the maximum density value. ...

A pretreater stain remover composition and method of using it is described. The composition comprises a siloxane based surfactant combined with a cosurfactant. Optionally, an antiredeposition polymer, enzymes and enzyme stabilizing system are added to effectively remove both oil and water based stains from a variety of fabrics.

A fuel assembly for a boiling water reactor comprising a first group of fuel rods (3a) which are of full-length design and which have a substantially constant cross-section area in their longitudinal direction, a second group of fuel rods (P) which consist of part-length fuel rods (3b) arranged in the lower part of the fuel assembly, or of fuel rods which in the upper part of the fuel assembly hav...

A heat sensitive jacket label (10a) for a battery comprises a base (1) made of a heat-shrinking film, a metal layer (2) provided on a back surface of the base, a heat-resistant insulating layer (6) provided on the metal layer, and a heat sensitive adhesive layer (3) on the insulating layer. The base (1) heat-shrinks at a temperature at least 15 DEG C higher than a temperature for effecting adhesio...

The edge material (3) is such that the cover can be placed both within e.g. a pipe and outside on a pipe connection of the same nominal standard dimension as the pipe.

Spent black liquor from a pulp bleaching process is burned in a soda recovery boiler(2). Primary, secondary and tertiary combustion air for boiler is preheated to improve combustion efficiency. The air streams are heated in heat exchangers(6,10,13) using the effluent(21) from the bleaching process. The effluent is in turn cooled sufficiently for purification in biological treatment means.

PURPOSE: A method for manufacturing a high tensile steel having a tensile strength of 120 kgf/mm2 level is provided, which has a high toughness of 80 Jules or more of impact energy at -40 deg.C by quenching-tempering the reheated steel again after directly quenching the high tensile steel and appropriately reheating the steel differently from an existing direct quenching-tempering heat treatment m...

In a memory in which a memory cell array 200 and a subword drive circuit SWD are alternately arranged in a row direction in addition to an SA array 170 and a cross portion (SWC) alternately arranged, there are arranged an interface circuit 100 between a global I/0 line GIOT/B and a local I/O line LIOT/B in a first cross portion SWD1, nMOSs Q2, Q4, and Q5 of an SA control circuit in a second cross ...
