In an automatic winder comprising plural winding units, a preset yarn quantity per lot and a residual quantity of yarn to be taken up are grasped upon generation of a full-loaded signal, then the number of operating winding units is decreased gradually, allowing operation of only winding unit or units of a number corresponding to the residual quantity of yarn to be taken up.

A method for preventing abnormal splicing. When two or more yarns are sucked from the package by the suction arm or when a slab or other disorder is detected by the detecting device, the yarn is cut in response to a yarn cutting signal from the detecting device, and after completion of the splicing operation, the yarn is forcibly cut again and the splicing operation is conducted again.

A separation/detection column that can detect a component separated by a separating agent having an optical responsivity which is the same as that of a component in a sample. The separation/detection column is configured by filling one end of a tube 1, having an ultraviolet transparency, with a first filler that has an ultraviolet responsivity and a separation ability to separate the component in the sample, and by filling the other end of the tube 1 with a second filler that has an ultraviolet responsivity which is different from that of the first filler and does not have the separation ability via a spacer 4 constituted by quartz wool, and moreover by inserting an end cap 5 constituted by quartz wool into the other end of the tube 1.

A moving iron type cartridge comprising a mounting base, a pair of permanent magnets for right and left channels secured to said mounting base, yokes for the right channel secured on the pole sides of said permanent magnet for the right channel and partially to the mounting base and having a coil wound thereon, yokes for the left channel secured on the pole sides of said permanent magnet for the left channel and partially to the mounting base and having a coil wound thereon, a damper case positioned at the end portions of said yokes and secured to the mounting base, a damper housed in said damper case, and a cantilever secured to said damper and having a stylus fixed to the tip thereof, whereby the stylus replacing operation can be easily performed and the outputs of a high level can be obtained.

A thin-layer chromatography plate and a thin-layer chromatography uses a thin-layer chromatography plate that has a first separating agent layer, which has the same optical response as the sample, and a second separating agent layer, which is disposed adjacent thereto and has an optical response that is different from the aforementioned optical response; carries out development of the sample in the first separating agent layer; thereafter carries out further development of the spots from the first separating agent layer toward the second separating agent layer; and detects the spots in the second separating agent layer through exposure to ultraviolet radiation or a color-development treatment with a coloring agent.
摘要:
A moving coil type of carriage for reproduction of sound on stereo discs in which there are four substantially flat pole faces arranged in square configuration facing mutually inwardly to define a central space and forming first and second opposed pairs. Permanent magnets are provided for magnetizing the first and second pairs so that the opposed pole faces are of the same polarity and adjacent pole faces are of opposite polarity. A first coil in the central space has its axis parallel to the first pair of pole faces with the turns thereof spaced along and lying closely adjacent such pole faces. A second coil in the central space has its axis parallel to the second pair of pole faces with the turns spaced along and lying closely adjacent such pole faces, the coils being secured together to form a square prism with the axes of the coils at right angles to one another. The coils are mounted upon a shank or cantilever of non-magnetic material arranged along a central axis which is substantially perpendicular to both of the coil axes. Finally, means are provided for resiliently supporting the shank so that movements of the stylus in two directions produce axial movements in the respective coils.

An improved moving coil-type phonograph cartridge producing reliably higher output and being easily manufactured is provided. Moving coils disposed in the center of a gap in magnetic circuit of permanent magnet and pole pieces is supported rotatably about a fulcrum positioned out of coil bobbin and an axial line of the gap so that coil sections on remote side from the fulcrum will transverse magnetic fluxes in the gap with a larger rotation radius and at a higher velocity than those of the other coil sections on fulcrum side. Further, at least a pole piece on the fulcrum side has a cavity surrounding the fulcrum so that the fluxes will be distributed to be circumferentially away from the fulcrum whereby the coil sections on the fulcrum side will be disposed out of the fluxes. Electromotive force eventually produced in the coil sections on the remote side from the fulcrum is larger than that produced in the other sections so that effectively and reliably higher output can be obtained.

An anchor removing device is constituted by providing a wedge shaped breaking means tapered in the drawing-out direction, which is temporarily secured to the tip portion of an anchor steel member and a tension steel member encompassed with sheath coupled to the wedge shaped breaking means. After this anchor removing device has been inserted into anchor hole which is bored in the ground, a hardenable filler material is injected into the anchor hole to form an anchor body. The hardenable filler material may produce voids or contains a foreign material of a low rigidity, which produces the effect similar to that of voids, such as air bubbles. The material may be foamable polystyrene and a cork of a given porosity. Typical example of the hardenable filler material is a foamed concrete milk. At the time of removing the anchor, the edge shaped breaking means is withdrawn by pulling the tension steel member with a jack or the like. Simultaneously with the withdrawal of the wedge shaped breaking means, the breaking means will break the anchor body covering same, thereby detaching the anchor body from the anchor steel member.
