摘要:
In an insulated type switching device, during rotation of a movable conductor 19 around a pivotal axis 35 between a stationary conductor 16 and a ground conductor 17 all of which are disposed in a vacuum vessel 12, the movable conductor 19 uninterruptedly takes four positions of closing position Y1, opening position Y2, disconnecting position Y3 and grounding position Y4, thereby a series of switching operations can be performed uninterruptedly, the operation and handling thereof are facilitated as well as the size of the insulated type switching device is reduced.
摘要:
A vinylidene fluoride polymer binder solution for forming an electrode for a non-aqueous-type battery is formed by adding an acid, preferably an organic acid, as a stabilizer to a solution of a vinylidene fluoride polymer in an organic solvent. The acid is preferably added in an amount sufficient to ensure a pH of at most 9 when measured with respect to a 10-times dilution of the binder solution with deionized water. The acid addition is effective for preventing a problematic viscosity increase in the binder solution and also gelling of an electrode-forming composition formed by adding a powdery electrode material in the binder solution.
摘要:
A centrifugal type counterflow contact apparatus having a rotary body or drum intergrally mounted on a rotary shaft, and a plurality of ring members disposed within the rotary body such that circumferential slits are defined between the adjacent ring members in the axial direction of the rotary drum. The ring members have a cross sectional configuration inclined with respect to the axis of the rotary body. A light liquid is introduced into the periphery of the rotary body while a heavy liquid is introduced in the center portion of the rotary body. The heavy and light liquids flow countercurrently through the slits between the ring members under the centrifugal force produced by the rotation of the rotary body, whereby extractability can be improved and accumulation of solids entrained in the feed can be avoided.

A high-density textile fabric produced by arranging, as warps and wefts, identical or different continuous filaments yarn at least 40% by weight of which are formed of filaments having a filament denier of 1.1 or less and which have a total denier of 120 or less, wherein cross-sectional overlaying coefficients, W.sub.p and W.sub.f, of the warps and wefts constituting said textile fabric simultaneously satisfy the following (a) and (b).(a) 1.30 .gtoreq.W.sub.p .gtoreq.1.10(b) 1.20 .gtoreq.W.sub.F .gtoreq.0.85Since the high-density textile fabric of the present invention not only exhibits high tearing strength but also has excellent water resistance performance in spite of its small thickness and light weight, it can be widely used not only as a closing material for ski wear, windbreakers, outdoors wear, coats, working clothes and operating gowns, but also for a shower curtain, a table cloth and a piece of cloth for an umbrella.
摘要:
A method for treating a wash waste liquor, which comprises treating fibers which have been dyed by applying a dye liquor containing a solution or dispersion of a non-ionic dye in a high boiling water-soluble organic medium or a mixture of it with a low boiling medium and then heating the fibers, with a low boiling organic solvent capable of dissolving the high boiling water-soluble organic medium, thereby to wash out the unfixed dye and the high boiling water-soluble organic medium remaining on the surface of the fibers; concentrating the wash waste liquor by evaporating at least a part of the low boiling organic solvent contained in the waste liquor; and extracting the high boiling organic medium from the concentrate using water.

A carbonaceous electrode having improved capacities for doping and dedoping of a cell active substance, such as lithium, and suitable for a non-aqueous solvent-type secondary battery, is constituted by a carbonaceous material having a pore volume of at least 0.55 ml/g of pores having a pore diameter of at most 5 &mgr;m as measured by mercury injection method, a potassium content of at most 0.5 wt. % as measured by fluorescent X-ray analysis, and a specific surface area of at most 100 m2/g as measured by nitrogen adsorption BET method. The carbonaceous material is advantageous produced by carbonizing a carbon precursor of plant origin having a potassium content of at most 0.5 wt. % as measured by fluorescent X-ray analysis, in contact with a stream of an inert gas optionally containing a halogen gas at a temperature of 700-1500° C.

A nubuck-like woven fabric comprising a two-layered structural yarn wherein ultra-fine polyester multifilaments are primarily disposed in a sheath portion and polyester multifilaments having a larger single fiber thickness are primarily disposed in a core portion, and having an apparent specific gravity of 0.35-0.7 and a shear rigidity of 0.5-1.2 gf/cm.multidot.deg. This woven fabric is produced by a method wherein a woven fabric of a two-layered structural yarn composed of (i) side-by-side type or islands-in-sea type composite multifilaments comprising (a) a readily soluble ingredient and (b) ultra-fine multifilaments-forming ingredient and (ii) highly shrinkable multifilaments, is subjected to a treatment for dissolving and removing ingredient (a) without substantial shrinkage of the two-layered structural yarn, then, the woven fabric is shrunk in a widespread state.
