摘要： An apparatus in accordance with the present invention sequentially fixes the wavelength of a light beam irradiated from a light source whose oscillation wavelength sequentially varies to a plurality of different wavelengths to a recording medium to required wavelengths each capable of forming a hole at absorption spectrum of the recording medium, synchronizes timing of change of the wavelength of the light source with timing of recording or regenerating each bit of information, records the optical hole formed in a manner that each bit of information corresponds to the wavelength varying in sequence, and detects the formed hole to regenerate information. Furthermore, the holes formed by the same wavelength are recorded at the positions separated by a distance capable of avoiding interference, while the holes formed by different wavelengths in correspondence to each bit of information are recorded at nearly the same position while that position is slightly displaced at a time, and thereby information is multiple-recorded with high density.

摘要： In an information storage apparatus having an error-correcting code, wherein digital information and check symbols are stored in groups of codewords which are divided into blocks of equal size and a synchronization field for data synchronization is added to each block, a detector detects errors in consecutive synchronization fields when the digital information is read, and a flag-setting circuit sets dropout flags when a signal from the detector indicates an error in consecutive synchronization fields. The flags are set from the last synchronization field that is correctly detected before the error up to the first synchronization field that is correctly detected after the error. In decoding the codewords, the errors in them are corrected with reference to the dropout flags.

摘要： A multi-nozzle weft insertion device which includes a weft guide which uses the hydrodynamic principles of fluid flow around a streamlined object to direct wefts from plural nozzles into a channel which can be centrally located with respect to the nozzles. The wefts are pulled along the contour of the guide, which is streamlined toward the channel, by a flow of high pressure air. The wefts can be kept from becoming entangled by adding a partition wing between the nozzles. If the channel is not centrally located each weft can be made to approach the channel by moving a different distance and from a different angle by varying the shape of the guide associated therewith. Both horizontal and vertical deflection of the weft can be controlled by shape.

摘要翻译： 一种多喷嘴引纬装置，其包括引纬导纱器，其使用围绕流线型物体的流体流动的流体动力原理将纬纱从多个喷嘴引导到可相对于喷嘴居中定位的通道中。 通过高压空气的流动，纬纱沿着引导件的轮廓被拉向通道。 通过在喷嘴之间添加分隔翼，可以防止纬纱缠结。 如果通道不在中心位置，则可以通过改变与其相关联的导向件的形状，通过移动不同的距离和从不同的角度来使纬纱靠近通道。 纬纱的水平和垂直偏转都可以通过形状来控制。
