A creel which can deliver untwisted yarns from bobbins in a weaving machine while at a same time twisting them or else twisting some of such untwisted yarns in the S twist and the remaining untwisted yarns in the Z twist with relative low investment for equipments. The creel employs a mechanism similar to a ring twisting mechanism and includes a required number of spindles for rotating bobbins sup...

A new superabsorber which gels and cross-links as hydrated has been developed. The superabsorber contains a branched-chain polyanionic carbohydrate such as carboxymethylcellulose, a cross-linking agent, and a hydrophobic carboxylic acid. The superabsorber is biodegradable and non-toxic.

A magnet system for magnet valves for controlling liquids including an electromagnet and a permanent magnet that produces magnetic fluxes, the magnetic fluxes of which are oriented opposite one another in a working air gap formed between a free-floating armature and a magnet pole. To attain a course of the force of attraction acting upon the armature that becomes negative beyond a certain excitati...

High molecular weight thermoplastic polyurethane resins with narrow molecular weight distribution and good physical properties are prepared by regenerating thermally degraded and/or off-grade thermoplastic polyurethane resins. The regenerated high molecular weight thermoplastic polyurethane resins do not present any processing difficulties inherent to high molecular weight resins.

A microcomputer (18) of this invention includes an internal memory (3, 4). These memories are connected to internal buses (21, 22, 23, 41, 43, 45) and external buses (31, 32, 33, 34) through bi-directional buffers (7, 8, 9). This microcomputer also includes a buffer controller (10) for determining whether an access by a control section (2) is made to the internal memory (3, 4) or the access is mad...

PURPOSE:To position a loaded load to a proper position to a station by detecting the load to a car body in the car body moving direction so as to correct the truck stop position to the station. CONSTITUTION:A couple of left/right projectors 4 are provided to a truck B to detect the stop position to a unloading station and stop control is applied by receiving a reflected light from a reflecting bod...

PURPOSE:To enable a stabilized driving frequency, a small size, high efficiency, and a long life by connecting an EL(electroluminescence) and a choke coil in series and setting the choke coil at such inductance as to give a higher reso nance frequency to the serial circuit of the EL and the choke coil than a.c. voltage. CONSTITUTION:An EL and a choke coil L1 are connected in series and the inducta...

PURPOSE:To make an electroluminescent display panel free of light bleeding by using a material consisting of an electroluminescent substance stuck to an anodized aluminum oxide membrane as an electroluminescent light-emitting layer. CONSTITUTION:An electroluminescent layer is composed of a material consisting of an electroluminescent substance stuck to an anodized aluminum oxide membrane. The anod...

PURPOSE:To obtain an EL(electroluminescence) device having high water- proofness even under the severe using conditions by using resin having a neutral ity of 95% or more as a highly water-absorptive resin. CONSTITUTION:Resin having a neutrality of 95% or more is used as a highly water-absorptive resin. As the highly water-absorptive resin, acrylic acid poly mer, copolymer of acrylic acid and viny...

PURPOSE:To use a cracking tube by cutting the straight-tube part of the cracking tube before a stable oxide film formed on the inner surface of the cracking tube becomes unstable during the initial operation in a production process for ethylene, removing the oxide film on the inner surface and rewelding the cut straight-tube part for use. CONSTITUTION:The straight-tube part 2 of a cracking tube 1 ...
