Abstract: A method for producing a shear element having protrusions on the skin contacting surface thereof, including the steps of coating an electrically conductive surface with a photoresist, exposing the photoresist to a hold pattern and developing the photoresist to produce a grid pattern wherein the electrically conducting surface is exposed, the grid pattern defining hole areas wherein the electrically conductive surface is covered by islands of photoresist of a predetermined thickness, introducing irregularities into the surface elevation of the exposed grid, the surface irregularities being of lesser dimension of the thickness of the photoresist islands, depositing an intermediate foil onto the exposed grid overlying the introduced surface irregularities, the intermediate foil being of sufficient thickness to extend above the photoresist islands when deposited, depositing a shear foil overlying the intermediate foil, and removing the shear foil from the intermediate foil, thus producing a shear foil having protrusions on the skin contacting surface thereof but having relatively smooth surface in the regions surrounding shear openings corresponding to the locations of the photoresist islands.

Abstract: This slide switch includes: a casing formed in a hollow box shape with an open top; several fixed contacts on the bottom surface of the casing and several terminals connected to them extending to the outside of the casing; a cover mounted to close the open top of the casing, formed with a hole opposed to the fixed contacts; a slide member disposed inside the casing, which has a control portion protruding out through the hole in the cover and a movable contact portion made of a resilient electrically conducting material which bears against the internal bottom surface of the casing and thereby produces a biasing force on the slide member to impel it in the direction towards the cover; and a seal member interposed between the inside of the cover and the side of the slide member facing it, the seal member being squeezed between the slide member and the cover, a seal between the inside of the casing and the outside thereby being produced. The movable contact portion of the slide member, according as the control portion of the slide member is moved from outside the casing, selectively connects together a combination of the fixed contacts. By this seal member being provided, a good sealing performance for the switch is available, and therefore, when the switch is soldered to a printed circuit board and a cleansing fluid is thereafter used for cleansing off solder residue, no contamination is introduced into the slide switch.

Abstract: An optical transmission system is described wherein light is transmitted from a transmitter (Tx) to a receiver (Rx) by at least one transmission optical fiber (11). The system includes a dispersion transformer (13) which receives light from one of the components, compensates for or transforms the delay distortion of the various wavelengths transmitted through the system, and provides the next component in the system with a compensated or transformed light beam. The dispersion transformer (13) comprises means for receiving light from one of the components and dispersing/separating the light into a plurality of spatially separated beams which are directed onto the endface of a multimode optical fiber (16). The position of each beam on the endface of the multimode fiber (16) is a function of the velocity with which the light that forms the beam propagates through the transmission optical fiber (11). The multimode fiber (16) is characterized by a refractive index profile and a shape which are such that the modes excited therein are propagated therethrough with appropriate delays to generate an output pulse of desired width. Dispersion can be reduced or increased. Light emanating from the multimode fiber (16) is coupled to the next adjacent component of the system.
