Abstract: A solid electrolyte sheet capable of increasing rigidity near an end surface of the solid electrolyte sheet, and a solid electrolyte secondary battery used with the solid electrolyte sheet are provided. A solid electrolyte sheet 10 includes a base 11 formed in a plate shape containing a solid electrolyte, and a plate-shaped reinforcing part 12 formed on an outside of the base, in which the reinforcing part 12 is made of a combination of two electrical insulating members different in material, and higher in rigidity than the base 11. Since rigidity near the periphery of the solid electrolyte sheet can be increased, a risk of damage near the periphery of the solid electrolyte sheet can be reduced.

Abstract: The invention provides a thermoplastic elastomer nonwoven fabric roll that exhibits minimal longitudinal wrinkles and minimal delayed restoration when unrolled, and method and apparatus for producing the same. Thermoplastic elastomer filaments that have been melt-spun are piled on a belt conveyor thereby forming a sheet of nonwoven fabric, that is guided to a rotating roller disposed above the transportation zone of the belt conveyor and peeled off therefrom. Since minimal tension is applied to the nonwoven fabric during processing, the nonwoven fabric can be unrolled with little stretching by applying relatively little tension to the nonwoven fabric. By the method of this invention, a nonwoven fabric roll with unrolling tension of 0.25 g/cm/basis-weight or less can be formed.

Abstract: A polyurethane elastomer fiber non-woven fabric contains polyurethane elastomer fiber filaments melt-bonded with one another, and has a tensile elongation of 100% or more, a 50% elongation recovery of 75% or more and a tear strength per METSUKE of 5.5 gf or more. The non-woven fabric can be prepared by a method of providing a thermoplastic polyurethane elastomer having Shore hardness A of 92 or more, drying the elastomer to a water content of 150 ppm or less, and melt-spinning and, at the same time, spraying it together with a high speed gas stream so as to deposit and laminate the elastomer into a sheet form. A synthetic leather using the non-woven fabric is also provided. The non-woven fabric has not only an excellent elasticity but also high tear strength.

Abstract: A polyamide/polyurethane composite filament yarn, contains a filament having a polyamide sheath component and a polyurethane eccentric core component exposed, through a neck portion of uniform width, on the surface of the filament. The filament is manufactured by a process comprising inserting, immediately before extruding from a spinneret orifice, a molten polyurethane flow, at an oblique angle from above, into a molten polyamide flow flowing down in a conduit, so that a small part of the polyurethane flow radially projects in a restricted width through the thinnest portion of the polyamide flowing flows down the inner wall of the conduit.

Abstract: A tire tread has a total of four circumferential ribs and three circumferential grooves. The four ribs include two intermediate ribs and two outer ribs, and the three grooves include a center groove and two outer grooves. The two intermediate ribs are between the center groove and the two outer grooves, and the outer ribs are on the opposite sides of the outer grooves from the intermediate ribs. Rib cross slots and cross sipes extend outwardly from the outer grooves into the intermediate and outer ribs in herringbone patterns. The cross slots and cross sipes extend less than the full width of the ribs to provide the intermediate ribs with circumferential inner portions adjacent the center groove that are devoid of cross slots. These circumferential inner portions of the intermediate ribs have a plurality of circumferentially-spaced cross sipes that do not intersect the center groove.

Abstract: A main rocker arm driven by a first cam, and a sub-rocker arm driven by a second cam larger than the first cam, are supported adjacent to each other. A sliding member which moves together with the sub-rocker arm, and a contact piece which comes into contact with the sliding member according to the slide position of the sliding member, are provided on the main rocker arm. The sliding member moves between a position where it is in contact with the contact piece and a position where it is not in contact with the contact piece according to the engine running conditions. The sliding member and contact member are constructed of iron or an iron alloy, while the main rocker arm is constructed of aluminum or an aluminum alloy. The construction of the cam change-over mechanism is therefore rendered lightweight, and machining of the main rocker arm is rendered facile.

Abstract: A cam shaft assembly comprises a first coupling between a drive collar rotatable with a driving shaft and an annular disc at a first position spaced from the shaft axis, and a second coupling between the disc and said hollow cam at a second position angularly spaced from said first position with respect to the shaft axis. The first and second couplings are so spaced from the shaft axis that they are at varying distances from the axis of the disc during operation. Each of the first and second couplings has a movable connection with the disc to permit the variation in its distance from the axis of the disc. The disc is rotatably supported in a disc housing. A control rod is mounted for rotation and has an eccentric control cam which controls movement of the disc housing. A pivot shaft extends through the disc housing for allowing movement of the disc housing following the eccentric control cam in which said plurality of hollow cams are disposed.
