    摘要: A switch using an improved method of optically-triggered avalanche breakdown which can produce pulses of 100 picoseconds or longer duration that can deliver five kilovolts into 50 ohms using a standard laser diode. A semiconductor block is provided with contacts on opposing sides across which a high-voltage less than the avalanche breakdown voltage is applied. One of the electrodes is on a mesa on one side of the block. The mesa is then irradiated with electromagnetic radiation. The wavelength of the radiation and the absorption coefficient of the semiconductor block are chosen so that the absorption depth of the majority of the radiation is less than the distance between the contacts. This results in a conduction area where absorption occurs, thus applying most of the high voltage across the distance beyond where the radiation is absorbed. This provides field compression and generates an avalanche breakdown field across the remaining distance of the semiconductor block.

    摘要: A fastener for securing a rail to a wire shelf having a plurality of support rods extending in parallel spaced-apart fashion. The fastener has a fastener body with an elongate rail engaging flange, a shelf engaging flange, and a connecting shaft portion extending between the rail engaging flange and the shelf engaging flange. The rail engaging flange is insertable through an elongate opening of an the rail in a first orientation and, upon rotation of the fastener, the rail engaging flange is configured to extend across said elongate opening thereby restricting withdrawal therefrom, while the shelf engaging flange traps a support member of the shelf thereby interlocking the associated rail to the associated shelf.

    摘要: A method for cleaning or restoring a surface using a mop that is attached to a carrier block. A flowable pesticide or restorative material is applied and removed by passing the mop over and in contact with the material that is applied in closely timed relationship. The method further utilizes different mops attached to the carrier block for each phase, one of which has grommets for attaching the mops to the carrier block.
