Abstract: An object of the present invention is to provide a sock which offers a fit, and does not cause fatigue, blood congestion, or the like if worn for a long period of time. The sock has a length from a toe to at least an ankle, and is knitted from a knitting yarn. The sock has a base knit structure knitted at an inside half region of an arch part of the sole from an upper thread and under thread, and has an auxiliary thread further inserted together with the upper thread, so as to form a knitted part which is contracted and reduced in extensibility.

Abstract: [Problems] To provide a novel chip useful for treating cells and the like which has a mechanism and a structure wherein the size of a hole pattern is arbitrarily changed so that cells can easily move in and get out from the hole in scattering or collecting cells but can hardly get out from the hole during washing or antigen-stimulation. [Means for Solving Problems] A chip comprising a crosslinked product of a temperature-responsive polymer as a constituting member and being provided with a film having a hole pattern on the surface of a baseboard. A method of producing a chip which comprises a crosslinked product of a temperature-responsive polymer as a constituting member and is provided with a film having a hole pattern on the surface of the baseboard.

Abstract: A prober that has improved positional precision of probing without reducing throughput is disclosed.

Abstract: There is a problem in that when the demand accuracy with respect to a semiconductor pattern dimension comes close to a resist molecule size with miniaturization, the device performance is deteriorated due to edge roughness of a resist pattern to exert a bad influence on the system performance. The present invention overcomes the problem by the procedure in which super-molecules which are small in dimension as compared with the conventional polymers are used as main components, the reaction number required for the change of molecule solubility is made constant and as large as possible, and an acid generator is made clathrate or combinatory n super molecules to make an acid catalyst concentration large. As a result, it is possible to form a pattern of molecular accuracy with high productivity even with respect to the pattern dimension less than 50 nm, thereby realizing the high performance system.

Abstract: The purpose of this invention is to provide taping socks which hold the ankle so as to protect the instep or the Achilles' tendon and prevent intorelance during walking or exercising. In the taping socks which have tightening parts woven in the socks, the first tightening part 7a is to tighten the Achilles' tendon and to be knitted around an ankle part S00, and a second tightening part 7b is to tighten an arch part P00 and to be knitted around the instep part 5. The said first tightening part 7a and said second tightening part 7b are crossed in an X shape at a flection part of front side to protect the Achilles' tendon and the instep part as well as hold the ankle part S00.

Abstract: There is provided a negative radiation-sensitive composition, which is suitable for exposure of a far ultraviolet light comprising a wavelength 193 nm of ArF excimer-laser, freed from causes of resolution deterioration such as swelling due to permeation of a developer and residual of a resist film between lines of the pattern, and capable of forming a high resolution pattern. The radiation-sensitive composition comprises a polymer of an acrylic acid ester having a &ggr;-hydroxycarboxylic acid in its ester moiety and a photo-acid generator.

Abstract: An external magnetizing method and external magnetizing apparatus for a rotary electric apparatus having internal permanent magnets, which obtains permanent magnetization of metal pieces fixed along the internal circumference of a yoke from the outside of the yoke while the rotor is situated within the yoke. The external magnetizing method includes the steps of creating the permanent magnets by applying a voltage from a capacitor power source to a yoke magnetizing device adjacent the external circumference of the motor yoke, then incrementally rotating the rotor in its normal rotating direction and thereafter reapplying the capacitor power source voltage to the yoke magnetizing means to again magnetize the metal pieces to obtain a more uniform magnetization when using a capacitor power supply .
