Abstract: Provided is a power generation/transmission device capable of obtaining stable power by utilizing rising and falling motion of rods and rolling motion of a spherical body. The power generation/transmission device includes: drive rods F1 to F3 capable of rising and falling in a vertical direction; a drive rotating disc 3 supported to be three-dimensionally rotatable about a first universal joint 41 to rotate on a conical trajectory along a circular track of a first angle restricting plate 43 disposed below the drive rotating disc 3; and a first spherical body 32 placed on the drive rotating disc 3 to be capable of rolling motion. The drive rotating disc 3 is rotated by the rising and falling motion of the drive rods F1 to F3 and the rolling motion of the first spherical body 32.

Abstract: A cylindrical filter which is easily produced and has a high withstand strength, a high filtration accuracy and a long filtration life; a microfine fiber web and a non-woven fabric suitable to a production of such a cylindrical filter; and processes for producing such web, non-woven fabric and cylindrical filter, are provided, the web consisting of microfine mixed fibers spun according to melt-blown process, the mixed fibers consisting of high melting point microfine fibers and low melting point microfine fibers having a melting temperature difference of 10° c. or more, the low melting point microfine fibers being contained in a quantity of 10 to 90% by weight in the mixed fibers; the non-woven fabric being obtained by heat-treating the web; and the cylindrical filter being obtained by winding up the web or the nonwoven fabric, followed by heat-treatment.

Abstract: A process for plating an electrically nonconductive substrate by the following sequence of steps:(1) a step of treating an electrically nonconductive substrate with a solution containing a silane coupling agent;(2) a step of treating the electrically nonconductive substrate from said step (1) with a solution containing an anionic surfactant;(3) a step of the electrically nonconductive substrate from said step (2) with a solution containing a palladium compound and at least one nitrogen-containing sulfur compound selected from among thiourea and its derivatives;(4) a step of treating the electrically nonconductive substrate from said step (3) with a reducing solution containing at least one member selected from among sodium borohydride, sodium hypophosphite, hydrazine, dimethylaminoborane, hydroxylamine and glyoxylic acid; and(5) a step of forming an electroplating layer on the electrically nonconductive substrate from said step (4).

Abstract: A hotmelt-adhesive fiber sheet having a superior adhesion and sheet-form retainability is provided, which sheet is composed of substantially unstretched fibers of an average fiber diameter of 10 .mu.m or less composed of an olefinic copolymer or terpolymer composed mainly of propylene, the fiber contact points of the fiber sheet being hotmelt-adhered.
