Abstract: An image reading device includes: a CCD for reading an image on a document to output an image signal; a light source for switchingly emitting visible light and non-visible light; and lighting control means for controlling lighting periods of the light source. The lighting control means is adapted to perform control such that a first light source lighting period for applying non-visible light is longer than a second light source lighting period for applying visible light. The image reading device also includes splitting means for splitting the image signals outputted from the CCD into an image signal upon application of visible light and an image signal upon application of non-visible light.

Abstract: A three-dimensional corner lap joint preform and a method of forming a three-dimensional corner lap joint preform including a woven flange with one or more legs that extend from the flange. The legs may include one or more independently woven portions which allow formation of a corner without darting the leg or adding additional reinforcement. The independently woven portions may include warp fibers which are not woven into the preform. The unwoven area allows removal of a portion of the leg prior to formation of the corner, allowing the portions of the leg to overlap and form a lap joint.

The formulated oil has a composition that contains at least one branched hydrocarbon having at least about 25% of the carbons in the form of methyl groups, or at least one polyol ester of at least one branched mono-carboxylic acid. A lubricating engine oil having a composition that contains at least one branched hydrocarbon having at least about 25% of the carbons in the form of methyl groups, or at least one polyol ester of at least one branched mono-carboxylic acid. The lubricating engine oils are useful as passenger vehicle engine oil (PVEO) products.

Abstract: The invention relates to a method for conditioning the CdTe layer of CdTe thin-film solar cells without the use of CdCl2. Calcium tetrachlorozincate (CaZnCl4) is to be used instead of CdCl2 for activation, and the process parameters that have proven themselves over time are to be kept. The method involves the activation of the CdTe layer of semi-finished thin-film CdTe solar cells; calcium tetrachlorozincate is applied to the CdTe layer (4) and the semi-finished thin-film CdTe solar cell subsequently undergoes a heat treatment. The calcium tetrachlorozincate layer is preferably applied via methods from the prior art, for instance roller coating with an aqueous or methanolic salt solution, spraying on an aqueous or methanolic salt solution, an aerosol coating or a dipping bath.

Abstract: A vehicle includes a front wheel. A steering column assembly is coupled to the front wheel. The steering column assembly includes a steering wheel and a steering column coupled to the steering wheel. A steering rack assembly includes a rack coupled to the front wheel. The rack extends in a vehicle lateral direction and is translatable with respect to a body of the vehicle in the vehicle lateral direction. A steering knuckle assembly is coupled to the steering rack assembly by a tie rod. A tie rod disconnect feature decouples the steering knuckle assembly and the steering rack assembly upon movement of the tie rod beyond a predetermined distance.

Abstract: The present invention relates to an optical device and a method for manufacturing the same. The technical object of the invention is to realize a surface emitting body which allows heat generated from a light-emitting chip to be easily dissipated, eliminates the need for an additional wiring layer, and allows a singular light emitting chips or a plurality of light emitting chips to be arranged in series, in parallel, or in series-parallel. The present invention discloses an optical device comprising: a substrate; a plurality of light emitting chips disposed on the substrate; a plurality of conductive wires which electrically connect the substrate with the light emitting chips such that the plurality of light emitting chips are connected to each other in series, in parallel or in series-parallel; and a protective layer which covers the plurality of light emitting chips and the plurality of conductive wires on the substrate.

Abstract: A method of making a beam-box crash management system comprises forming a first shell (100a) from a first sheet metal blank by a hot forming process. The first shell has a high tensile strength beam portion (102a) and integrally formed there-with a first low yield strength crash box portion (104a) proximate a first end of the beam portion and second low yield strength crash box portion proximate a second end of the beam portion. The first shell also has an open face extending continuously along the beam portion and each of the first and second crash box portions (104a, 106a). A closing element (100b) is formed from a second sheet metal blank, and is fixedly secured adjacent to the open face of the first shell.

Abstract: A shirt press finishing machine has a torso for carrying a shirt and a pair of front part and rear part side press irons. Iron receiving surfaces of the front and rear parts of the torso are covered with cushioning sheet materials and long and thin bags expanded by gas are attached to both sides of the front and rear sheet materials over substantially the entire longitudinal length of the sheet materials.

Abstract: The present cartridge seal assemblies pertain to rotary lip-type seals. In certain embodiments, a sealing member is constructed of a relatively hard material that increases the lifespan of the sealing member. The sealing member is energized with a canted-coil spring, which in some embodiments includes an adjustable spring force. The present embodiments enable control of sealing force to achieve an appropriate sealing force between the sealing member and the shaft based on factors such as temperature, pressure, rotary speed, properties of fluid media, etc. to achieve longer seal life.

Abstract: A center clamping mechanism for a wheel assembly service machine such as a tire changer machine includes a back cone centering element projecting outwardly from a platen and configured to engage a center bore of the wheel rim hub mount pad from an inner side of the hub mount pad. The centering element may include a compliant element configured to at least partially support the weight of the wheel rim and tire when being clamped. A pivot arm defines a contact surface for the inner side of the wheel rim hub mount pad, and when the tire is rotated by an operator with the inner side in contact with the contact surface, an anti-rotate pin carried on the pivot arm may be adjusted in radial position relative to the drive axis to accommodate different lug holes at varying lug bolt circle diameters.

Abstract: A detector and methods for inspecting material on the basis of scintillator coupled by wavelength-shifting optical fiber to one or more photo-detectors, with a temporal integration of the photo-detector signal. An unpixelated volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides. This geometry provides for efficient and compact detectors, enabling hitherto unattainable geometries for backscatter detection and for energy discrimination of incident radiation. Additional energy-resolving transmission configurations are enabled as are skew- and misalignment compensation.
