Abstract: The image display device includes a liquid crystal display device having a liquid crystal panel and a backlight and a backlight controller for allowing the backlight of the liquid crystal display device to be bright when environment light is bright and allowing the backlight to be dark when the environment light is dark such that light leak (minimum luminance) which is defined by an extinction ratio of liquid crystal will not grow more than a specified degree. The image display device enables displayed images to be really discernible regardless of brightness of environment light (surrounding light).
Abstract: The present invention comprises a dense wavelength division multiplexing system which uses an automatic level control feedback circuit or loop (100) to maintain one of a plurality of selectable output power levels. In addition, to prevent the sidelobes of the individual channels from interfering with one another when power to the channel is increased, an optical bandpass filter (5) is placed in the optical feedback path of the ALC loop (100). Furthermore, if the frequency or wavelength drifts from the desired output wavelength, the output wavelength is tuned by cooling or heating the laser using a thermoelectric cooler (55) which is part of a thermoelectric cooler loop (110) that uses a calibration table to adjust for temperature/wavelength errors.
Abstract: A rubber-steel cord composite comprising a steel cord having, in a planar image of the steel cord formed by X-rays passing through the steel cord, a fraction R of the total area occupied by filaments of from 0.45 or more to 0.95 or less in an arbitrarily selected portion of the steel cord having a length of 15 mm in an axial direction of the cord, is provided. The length of 15 mm in an axial direction of the cord means a length of 15 mm in an axial direction of an actual cord and the fraction R of the total area occupied by the filaments is expressed as R=F/A, wherein A represents the total area of the cord and F represents the area of the cord occupied by the filaments.
An object of the present invention is to provide a pneumatic tire for passenger cars that shows no separation of the interface of adhesion during use, particularly during use in the run-flat condition, and exhibits excellent durability.
Abstract: A method, apparatus, and article of manufacture for a computer-implemented apportioning system. Work is distributed to processors in a multi-processor system. Initially, during bind-time, a scaling factor is determined for each processor. The scaling factor represents relative processing power in relation to each other processor. Then, portions of a total amount of work are distributed to each processor based on the determined scaling factor of that processor and a determined amount of work for an average processor.

Abstract: An electromagnetic wave radar device mounted on a car, which helps improve external appearance of a car without impairing radar function, and is fabricated using a decreased number of parts at a reduced cost. The electromagnetic wave radar device comprises an electromagnetic wave radar body 1 mounted on a car 2 and for transmitting and receiving electromagnetic waves of a predetermined frequency, and a radome portion made of a material which permits the electromagnetic waves to transmit through and covers the electromagnetic radar body, the electromagnetic wave radar body being disposed on the side of the back surface 30A of the bumper 30 of the car, and the radome portion being formed by a portion of the bumper of the car.
Abstract: A device for application to a body part of a patient to determine the physiological condition of the patient. The device includes a housing, in the form of a hollow socket closed at its distal end and open at its proximal end, for receiving the body part, a pressurizing device for applying a pressure field around the body part when received in the housing, and a sensor for sensing changes in the body part related to changes in pulsatile blood volume therein. The housing includes at least three contiguous but separate sections including a distal end section at its distal tip, a proximal end section at its opposite end, and at least one middle section between the end sections. The pressurizing device applies a pressure field to the portions of the body part received within at least the distal end section and the middle section of the housing. The distal end section is configured to apply pressure to all of the distal portion of the body part including its distal most tip.
Abstract: Computer for a bicycle includes a speed change with a chain transmission, including a plurality of front crown wheels (16) which can be driven in rotation by a pair of pedal cranks (18) and a plurality of rear sprockets (20), a first sensor (30) for providing an electric signal indicating the speed of rotation of one wheel of the bicycle, a second sensor (32) for providing an electric signal indicating the speed of rotation of the pedal cranks (18), and a third sensor (38) for providing an electric signal indicating which is the selected front crown wheel. The computer has a display (24) for displaying riding information of the bicycle, and an electronic control programmed so as to determine the number of teeth (Zp) of the selected rear sprocket as a function of said signals and as a function of stored data indicating the number of teeth (Zc) of the front crown wheels (16).
Abstract: A golf ball has a core and a cover and, the cover includes at least one thin spherical layer with a thickness of not more than 1.5 mm. The thin layer is molded by injecting an injection molding material at a selected fill speed which is correlated to the melt flow rate of the molding material. The invention facilitates the mass production of golf balls having thin spherical cover layers of uniform thickness which offer potential for further improvements in ball performance.
Abstract: A circuit board for mounting a bare chip in the form of a flip chip. A metallic foil for protecting circuits in a state insulated therefrom is arranged in an area where the bare chip is located.
Abstract: A process for producing an intravenously-administrable gamma globulin solution substantially free of contaminating viruses by fractionating an impure gamma globulin solution and then treating the purified gamma globulin, with a solvent-detergent for viral inactivation and a heat treating for viral inactivation. Thereafter, denatured impurities, residual solvent and aggregate generated by the heat treatment are removed from the gamma globulin.

Abstract: For measuring the volume, the process utilizes the same means as are used for reading an optical code, such as a laser scanner or CCD reader. A choice of different measuring procedures are proposed which suit different situations and are all based on scannings and readings performed on the object. Where required, the process can accommodate the inclination angles of the scan planes. The volume measurement is accompanied by the reading of an optical code provided on the object.
Abstract: An image display device is provided which comprises an antiglare surface having unevenness and pixels having a minimum pixel pitch (a) of about 10 to about 100 &mgr;m, wherein a ratio (Sm/a) of an average spacing of roughness peak (Sm) of said unevenness to the minimum pixel pitch (a) is about 0.4 or smaller. In the image display device, the generation of “glittering” can be restrained.

Abstract: An iterative method enabling a request plan to be established for an observation satellite. A plan consists in a succession of requests which are associated with pluralities of opportunities for satisfying said requests. The plan must also comply with a plurality of constraints. Each iteration k of the iterative method is made up of the following steps:
new opportunity is selected;
a provisional plan is derived from the preceding plan k-1 as calculated in-the preceding iteration, and from the new opportunity;
provisional plan is verified for compliance with said plurality of constraints;
the quality of said provisional plan is evaluated; and
it is determined whether the provisional plan should be confirmed as plan k as a function of the quality of said provisional plan and of the quality of said preceding plan k-1.
