A method of producing a particle-shape water-absorbing resin material is realized. With this method, it is possible to prevent deterioration of properties of the particle-shape water-absorbing resin material, and reduces damages onto surfaces thereof. This method is arranged such that (a) water-absorbing resin particles are surface-treated by using a crossing agent so that surfaces of the particles are cross-linked, (b) an additive for giving a function to the particles is added to the particles, (c) and a step of mixing the particles and the additive is carried out in a step of performing particle-size regulating treatment for the particles which includes agglomerated particles.

A tool-carrying assembly to be secured by a waist-encircling belt, and, additionally, by straps encircling the legs of a workman using the belt assembly. The assembly is thus stabilized, and enhanced weight distribution is achieved. Elements of the belt assembly include a waist-encircling band supporting a pair of laterally spaced, depending panels each carrying tool-accepting pockets. The pockets preferably carry visual markings and coding as well as other indicia identifying clearly the specific tools to be "housed" or carried in and to be returned to each pocket after use. Inventory control of the tools is thereby significantly enhanced. Pivotal flaps depending from the band-carried panels serve to cover the tools when not in use, and to prevent the tools from scratching or otherwise marring any article, or fixture, or "workpiece" requiring the workman's attention. The panels and the tools carried thereby are disposed in lateral, spaced zones at the wearer's sides (and not directly in the front of one's body) thus further to reduce any likelihood of the tools coming into damaging physical contact with an article being worked upon. That is, both frontal and rearwardly located zones about the wearer of the tool belt assembly are rendered essentially free and clear of all tools and other mechanical impediments. While wearing the tool assembly of the invention, a worker can, without any discomfort, lie upon and use a "creeper". Significantly, a frontal sector of the belt itself is covered with a relatively soft, non-marring protective pad, composition, or surface material effective to prevent possible damage from a workman's belt buckle. An additional feature of the invention is that the panels may be structured to constitute a core sandwiched between a pair of encasing sheet-like webs. The resulting composite is readily formable to provide selectable visual patterns, designs or indicia, for example, to identify product name or sources and / or to constitute decorations.

A belt-like article has fastening elements continuous attached along an entire periphery of a long tape main body. The belt-like article further includes engaging means capable of engaging with / disengaging from each other, each of which has an engaging portion provided at a predetermined position in a longitudinal direction of the tape main body. By winding the belt-like article spirally about an end portion thereof so as to engage the opposing fastening elements successively, a diversified types of the storage bodies can be obtained. Further, by engaging the engaging means with each other, the belt-like article can be used as a neck strap for hanging the storage body for accommodating an object. Therefore, the belt-like article is provided with not only an application as the belt-like article but also an application as a storage body for various objects, which are functionally related to each other, so that it can be used sufficiently for practical purpose.

A method is provided for fabricating a nano field-effect vacuum tube. The method includes providing a substrate having an insulating layer and a sacrificial layer; and forming a sacrificial line, a source sacrificial layer and a drain sacrificial layer. The method also includes forming a trench in the insulating layer; and forming a dielectric layer on the surface of the sacrificial line. Further, the method includes forming a metal layer on the dielectric layer to fill up the trench, cover the sacrificial line and expose the source sacrificial layer and the drain sacrificial layer; and removing the source sacrificial layer and the drain sacrificial layer. Further, the method also includes removing the sacrificial line to form a through channel; forming an isolation layer on the metal layer; and forming a source region and a drain region on the insulating layer at both ends of the metal layer.

A thrust bearing for a turbocharger of an internal-combustion engine is made of a copper alloy including a brass matrix and a needle-like Mn—Si-based compound dispersed in the brass matrix. Not less than 50% of the needle-like Mn—Si-based compound dispersed in a region from a surface of a sliding portion of the thrust bearing to a depth of 50 μm have a major axis extending from the inside of the sliding portion to the surface. The major axis makes an angle of 30° to 150° with the surface of the sliding portion when observed in a sectional view perpendicular to the surface of the sliding portion.

An adjustable roof platform which comprises a work platform having first and second ends and opposed top and bottom surfaces. A pair of first and second spaced apart support legs each having a first end and a second end and opposed top and bottom surfaces. The first end of the work platform is pivotally connected with the first ends of the support legs and the bottom surfaces of each support legs carries a replaceable foam layer. At least one member connects the first and the second support legs with one another and at least one adjustable arm adjustably connects the second end of the work platform to the support legs so that an angle, formed between the work platform and the first and second support legs, can be varied between about 0 degrees and about 45 degrees.

A housing includes a rear housing segment including a protruding post, a back plate disposed in front of the rear housing segment and including a protrusion, and a fastening member disposed between the rear housing segment and the back plate, and including a positioning cap, a positioning post, and an engaging hook. The positioning cap covers removably the protrusion. The positioning post protrudes from the positioning cap opposite to the protrusion and engages the protruding post. The engaging hook includes a clamping plate that cooperates with the positioning cap to clamp the board member there between, and an engaging block that removably engages an engaging hole in the board member.

A liquid crystal display device is disclosed, which can remove a defect generated from polishing and etching of a glass substrate. The LCD device includes first and second substrates assembled together with some spaces therebetween, each having an etched outer surface, and a passivation film outside the first and second substrates.
