摘要:
In chromium-free aqueous acidic washing solutions for cleaning the surfaces of aluminum and aluminum-alloy particles, so as to remove therefrom smut and lubricating oil left on the surfaces thereof after metal forming operations, which solutions contain from 0.2 to 4 g/l ferric ion and sufficient sulfuric and/or nitric acid to impart a pH of 2 or less to the solutionh (and which optionally may also contain fluoride ions up to a concentration of 0.5 g/l) there is provided a method of controlling the effectiveness of the washing solution in which the ferric ion concentration therein is monitored, conveniently by the oxidation-reduction potential of the washing solution, as shown in FIG. 3, and is controlled within the desired limits by adding when appropriate suitable amounts of oxidant capable of oxidizing ferrous ions to ferric ions and, separately or in conjunction therewith, a replenisher containing a source of iron ions.

There is provided an information processing apparatus for calculating an evaluation value representing quality of a moving image. A second acquisition unit is configured to acquire position information representing a position of a chart image in each frame image of the input moving image. A cutout unit is configured to cut out, from each frame image of the input moving image, a partial image including the chart image based on the position information and generate a converted moving image having the cutout partial image as a frame image. A conversion unit is configured to frequency-convert the converted moving image at least in a temporal direction. A calculation unit is configured to calculate the evaluation value based on a frequency component value obtained by the conversion unit.

A reading apparatus and method for reading data from a digital versatile disc includes a specification section configured to specify a predetermined position of content. A controller generates information indicating a predetermined portion from a position specified by the specification section. A storage section reads the predetermined portion from the digital versatile disc on the basis of the information generated by the generation section and stores the predetermined portion on a storage medium. A reading controller controls reading of data from the storage medium and the digital versatile disc.

A lubricating oil composition for a power transmission system, which is excellent in both of low-temperature viscosity property and shear stability, is provided. The viscosity modifier of a lubricating oil for a power transmission system according to the present invention comprises an ethylene/α-olefin copolymer (B) having the properties: (B1) an ethylene content in the range of 70 to 85% by mol, (B2) an intrinsic viscosity [η] in the range of 0.2 to 1.0 dl/g, (B3) Mw/Mn not more than 2.4, and (B4) a melting point, as measured by DSC, not higher than 60° C., or no melting point observed.
摘要:
An illuminator emits light obliquely to an end of an adhesive film. A CCD camera is provided in a direction perpendicular to the adhesive film to capture an image of the light reflected irregularly from the end of the adhesive film. A black plate is provided on a back side of the adhesive film. In the image obtained by the CCD camera, therefore, only the end of the adhesive film is displayed whitely in a line shape. A position of the adhesive film is determined based on a line corresponding to the end of the adhesive film. Since the light reflected from the end of the adhesive film is utilized, the position of the adhesive film can be determined accurately irrespective of a color of the adhesive film, a color of a base film to which the adhesive film is joined, and a depth of each color.

A test fluid measurement device includes an output acquisition unit for acquiring an output value from a urinary sugar sensor, when a reference fluid, set to a specified density, is applied to the urinary sugar sensor. By using this output value to set a reference value, a reference value setting unit calibrates the sensitivity of the urinary sugar sensor. During sensitivity calibration, an output value judgment unit determines according to an output value that is already acquired by the output acquisition unit whether or not the output value that is newly acquired by the output acquisition unit is suitable to be set as the reference value. After an output value is determined not to be suitable as the reference value setting, a reference fluid detection unit detects when more reference fluid from which another output value is to be acquired by the output acquisition unit has been additionally applied.

An alignment apparatus of this invention includes a holding stage that is larger in size than a semiconductor wafer, and an optical sensor that optically detects a position of a peripheral edge of the semiconductor wafer placed on and suction-held by the holding stage. The holding stage has a slits formed thereon vertically in a circumferential direction, and an outer periphery of the semiconductor wafer lies on the slits. The optical sensor is of a transparent type and includes a projector and a photodetector opposed vertically to each other with the slit interposed therebetween. The optical sensor measures the peripheral edge of the semiconductor wafer on the slits of the holding stage.
摘要:
A lighting rate is calculated from a video signal input in a plasma display device, and an output current of DC-DC converter, which is the same as a discharge current in a sustain period corresponding to the lighting rate, is synchronized with a generation timing of discharge current. With such a configuration, even if discharge current in the sustain period of each subfield is rapidly changed, a sustain pulse voltage can be kept constant.
