A weft picking system for an air jet loom is provided with a microcomputer as a controller. The weft picking system comprises a weft traction device including a pair of rollers, one of which is driven by an inverter motor. A weft yarn fed from a weft measuring and storing device can be placed between the rollers to be drawn toward a weft posture regulating nozzle. The weft posture regulating nozzle is arranged to project the weft yarn into the shed of warp yarns and regulates the posture of the weft yarn under the influence of air jet ejected from the nozzle and from a plurality of sub-nozzles. The rollers always rotate during a weaving operation of the loom. A change-over device is provided to change the weft yarn from a first state of being placed between the rollers to a second state of separating from the rollers or vice versa. A weft yarn slackened portion is unavoidably formed between the weft traction device and the weft posture regulating nozzle, due to a temporary difference in the tractive speed between the weft posture regulating nozzle and the weft traction device. A slackened portion deforming device is disposed between the weft traction device and the weft posture regulating nozzle to effectively deform the slackened portion in a manner to smoothen the slackened portion enough as to prevent any trouble in the weaving operation and any defects in the woven fabric.

An air jet loom is equipped with a weft storage device for detaining a weft yarn prior to weft picking through a weft inserting nozzle. The weft storag device includes a roller reel on which the weft yarn is wound in the shape of a coil. The roller reel consists of a plurality of rollers arranged in the shape of a reel in which the axis of each rollers is outside any of planes containing an axis of the roller reel. Some of the rollers are driven around their axis. An engaging member is movably disposed in the vicinity of the unwinding end section of the roller reel and normally engaged with the weft yarn but disengaged from the weft yarn during weft picking, thereby sharply reducing weft picking resistance applied the weft yarn to be picked into the shed of warp yarns.

A digital camera comprises an interchangeable lens unit and a camera body. The interchangeable lens unit is provided to form an optical image of a subject. A flash memory is configured to hold a correction coefficient table used to electrically correct distortion produced by the optical system. The camera body has a CCD image sensor, a correction coefficient acquisition part, an operation part, and a correction processor. The correction coefficient acquisition part is configured to acquire the correction coefficient table held in the flash memory. The operation part is configured to produce correction data by performing an interpolation operation or an extrapolation operation on the information obtained from the correction coefficient table. The correction processor is configured to correct distortion in the image data on the basis of information produced by the operation part.

A laminated material suitable for fabricating miniaturized security tags which have the uniform resonance frequency, and security tags obtained by using the laminated material, are provided. A manufacturing method of a laminated material for security tags characterized in that metal foils are laminated on both sides of a previously formed synthetic resin film, and security tags obtained by using the laminated material by the manufacturing method, are provided. Because the lamination is performed on the previously formed resin film, the amount of variation in thickness of the resin film is small, and the thin resin film can be precisely manufactured. Further, because the oriented film has a relatively high strength even for a thin film, the laminated material is easy to be etched for forming a circuit. The security tag obtained by using a previously formed resin film can satisfy both uniformizing the resonance frequency and miniaturizing the security tag simultaneously, and has an excellent performance.

An image processing apparatus for electrically correcting distortion of an input image to generate an output image, includes a correction processing section operable to sequentially read data of the input image for each pixel in an order of scanning, and perform distortion correction for each pixel of the output image using the read data of the pixel. The correction processing section outputs data of a pixel which distortion correction is completed, in an order different from an order of scanning the output image.

A solid-state imaging apparatus having color separation filters is provided which produces a signal with reduced chrominance and luminance moire and thereby improves resolution, and the spectral characteristics of the color filters for the solid-state imaging apparatus are so set that when the spectral characteristic of each color filter is multiplied by a prescribed coefficient, the sum of four or two horizontally adjacent pixels becomes approximately equal between two vertically adjacent lines. A coefficient multiplying circuit multiplies an output signal from each color filter by the prescribed coefficient, and signal processing is performed.

An antenna switch apparatus and a switching method thereof including an antenna-input for cable broadcasting and an antenna-input for terrestrial broadcasting and satellite broadcasting, always receiving an OOB signal, and freely selecting one of a cable broadcasting channel and a terrestrial broadcasting channel or a satellite broadcasting channel is provided. In the antenna switch apparatus and the switching method, the terrestrial broadcasting signal is input to a select means, the cable broadcasting signal is split by a split means and the signals are input to an OOB tuner and the select means, then a signal selected by the select means is input to an A/D tuner. With this arrangement, one of the signal of the cable broadcasting channel and the terrestrial broadcasting channel or the satellite broadcasting is selected while keep receiving the OOB signal.
