The cage portion of a cage and roller assembly has two annular end rims joined by cross-bars around the periphery of each rim. The rims and cross-bars define multiple pockets which hold the rollers. The cross-bars are configured to contain the rollers within these pockets; in addition, coined ramp surfaces and land surfaces on the cross-bar outer surfaces extend radially outward farther than the o...

PURPOSE:To enhance forming efficiency and to prevent paste filling performance from being lowered by adding organic high polymer fibers coated with carbon and carbon black. CONSTITUTION:When organic high polymer fibers coated with carbon are added in active material, the skeleton of electron conductive net works is formed in green forming active material. The addition of particulate carbon black c...

PURPOSE:To improve electric discharging performance and long life performance by filling powder material having a larger hole than that of a separator under a filled condition, around a plate group of layered plate and a separator in a battery jar, and by holding a required and sufficient amount of electrolyte sulfate in the holes of the plate group and for the powder material. CONSTITUTION:A plat...

PURPOSE:To prevent formation of electrolyte into layer between a plate and a retainer. CONSTITUTION:An acrylic emulsion mixed liquid containing porous powder material (SiO2) is adhered to the surfaces of a plate and a retainer, which are opposed to one another, to form a mixed liquid layer. The plate and the retainer are layered in such a way that the mixed liquid layer is sandwiched therebetween....

A spring finger ply down for a tire building machine comprising an annular array of spring fingers, an annular support for the fingers and a constrictable clamp for securing each finger to the support at an axial interference between each finger and the support. The constrictable clamp includes an elastic band stretched circumferentially around the fingers and/or a clamping ring of relatively inex...

PURPOSE:To make it unnecessary to access a center during the supply of service, and in addition, to improve safety. CONSTITUTION:When a user inserts an IC card 6 into a terminal 1, and inputs a pass word Nc, a random number R is generated at the terminal 1, and the IC card 6 receives this, and when it coincides with the stored password, it generates the random number X, and produces a digital sign...

A urea-formaldehyde resin which cures highly exothermally is obtained by condensation of urea with formaldehyde in an alkaline medium and is characterised in that it is obtained by a) condensation in a first condensation step I of from 0.2 to 0.7 mol, preferably 0.5 mol, of urea with from 1.2 to 3 mol, preferably from 1.7 to 2.2 mol, of formaldehyde in the form of solid paraformaldehyde, in an ex...

Polyimide which is obtained by polymerization and consists essentially of recurring structural units of the formula (I): wherein X is a single bond or a hexafluoroisopropylidene group, is processed to a form of pellet, followed by heat-treating to obtain crystallinity of 5 % or more, and fed to an extruder to obtain articles.

PURPOSE: To access to a track on the surface of a moving medium storing data and to execute tracking by correcting tracking in the direction of a diameter. CONSTITUTION: A reflecting mirror 4 and a convergent lens 5 are fixedly fitted to a carriage 3 and tracking in the direction of the diameter is corrected through a mirror 6. The mirror 6 is turned with a shaft fixed on the frame of a read/recor...

PURPOSE:To prevent an insulating coating from peeling and lower the bonding loss between strands by coating the surfaces of superconducting strands to a specified thickness with an alloy layer of Ni alloyed with P, B, Cu, Zn, Co, W, Mo, etc. CONSTITUTION:A plurality of superconducting strands are inserted in a conduit tube to obtain a cable-in-conductor. At that time, the surfaces of the supercond...
