摘要:
Piecing method of a spinning machine whereby, after holding outside a twist device both a leading yarn ejected from the sliver guide entrance of a twist device in a stationary state and a sliver delivered by a re-operated draft device, the twist device is operated, the sliver supplied to the twist device and the fibers comprising the sliver are entangled in the leading yarn pulled from the twist device. The success rate of yarn piecing may be improved without detailed adjustment of the pulling timing of the leading yarn guided into the twist device and the supply timing of the sliver supplied to the twist device.

A method and apparatus are described for piercing severed yarn to a sliver in a spinning machine in a manner to prevent formation of an excessively long or frail piecing portion by passing leading yarn Y' through a twist device T; driving draft rollers 1, 2, which have been stopped following severance of the yarn to remove the thinned, tapered tip of sliver 6 from the front roller 4; and then introducing sliver for piecing into the twist device while removing a portion of the fibers constituting such a sliver to make the piecing portion thereof more nearly as thick as the leading yarn.

A false twisting method and device for twisting a yarn which runs under a predetermined tension includes an arrangement wherein the yarn is wound about a member such as a cylindrical member positioned approximately at the halfway point of the running of the yarn, and a yarn downstream of the wound member and a yarn upstream of the wound member intersect each other in a contacted state to provide a twist in the yarn.

There is provided a sock that causes no feeling of tightness or pressure when a toe is housed, has no connecting portion, causes no tightening of knitted fabric itself, and has good appearance. The sock includes a toe housing portion that forms a laterally asymmetrical substantially planar trapezoidal shape slanted to a thumb side that is provided continuously with a cylindrically knitted portion. The cylindrically knitted portion forms a sole portion and an instep portion. The toe housing portion is provided with a forward knitted portion for increasing thickness between a front portion and a back portion invertedly knitted to form a substantially planar trapezoidal shape, along contours thereof.

A yarn false twister in which an endless belt an a first rotary member are disposed across each other to constitute a nip point at which a yarn is twisted, and a second rotary member, on which the yarn is wound after the nipping thereof so that the upstream and downstream portions of the wound yarn cross in contact with each other, is provided coaxially with the first rotary member so that the second rotary member can be rotated independently of the first rotary member.

In a drawing false-twisting method, which draws a twisted yarn, heat-sets the drawn and twisted yarn, cools the yarn by making the yarn travel in contact with the surface of the guide groove of a cooling plate and untwists the yarn to obtain a textured bulk yarn, the yarn is moved laterally to spread the oil transferred from the yarn to the surface of the guide groove.

A metal oxide varistor is disclosed which a component of grain bodies comprised of zinc oxide and a component of grain boundary layers comprised of another metallic oxide, containing metal other than zinc wherein at least a portion of these starting materials comprised a fine particle powder prepared by a co-precipitatin method.The metal oxide varistor of the present invention is excellent in varistor characteristics such as non-linearity to voltage, life performances and capability of energy dissipation, is small in a scatter of the above characteristics between manufacture lots or within each lot at the time of manufacture, and has a good quality stability. Unexpected results are obtained when the co-precipitated fine particles are subjected to a refrigeration-dehydration type process.
