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 positive electrode active material which can improve cycle characteristics of a secondary battery is provided. Two kinds of regions are provided in a superficial portion of a positive electrode active material such as lithium cobaltate which has a layered rock-salt crystal structure. The inner region is a non-stoichiometric compound containing a transition metal such as titanium, and the outer region is a compound of representative elements such as magnesium oxide. The two kinds of regions each have a rock-salt crystal structure. The inner layered rock-salt crystal structure and the two kinds of regions in the superficial portion are topotaxy; thus, a change of the crystal structure of the positive electrode active material generated by charging and discharging can be effectively suppressed. In addition, since the outer coating layer in contact with an electrolyte solution is the compound of representative elements which is chemically stable, the secondary battery having excellent cycle characteristics can be obtained.

A process for manufacturing a hybrid component. To manufacture a hybrid component with electronic components in a possibly continuous manufacturing process, it is proposed according to the present invention that the electronic component be extrusion-coated with a hot melt adhesive melting at low temperature and to extrusion coat the intermediate product formed with a conventional plastic suitable for injection molding in an additional injection molding operation. On the one hand, damage to the electronic component is reliably prevented from occurring by this procedure, and, on the other hand, a hybrid component can be manufactured with a housing that is insensitive to external effects.

A laminar flow water jet system has a housing with a water channel, the housing creating a laminar flow in the water channel from the water flowing through the housing. A lighting element is provided with a controller. The laminar flow passes through at least one jetting element having a cup portion and a nozzle portion and jetting a laminar flow tube from the laminar flow passing through the water channel in the housing at the base portion. The laminar flow tube is ejected from the nozzle as a laminar flow jet having a smoothed tubular surface jacket and being lit by the lighting element. An additive source drips additive into the cup portion at a rate controlled by the controller, the additive being absorbed by capillary action by the laminar flow tube as it is passed through the nozzle to become the laminar flow jet. The absorption process drawing in air from the surrounding atmosphere and creating perturbations or bubbles within the laminar flow tube. In a further mode either an energetic pulse or an additive wave formed by increasing the volume of additive in the cup portion of the jetting element creates a wave perturbation or interruption throughout the laminar flow tube creating a variation in the laminar flow tube and the smoothed tubular surface jacket of the resulting laminar flow jet.

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.
