Abstract: An electronic control has a heat sink which is electrically isolated from electrical components mounted on a printed circuit board of the control by the printed circuit board itself. Thus, the use of additional materials which are thermally conductive but electrically insulating is avoided. A distributor sheet on the printed circuit board distributes heat substantially uniformly over its surface where contacted by the heat sink to promote heat transfer. The heat sink is shaped to permit devices to be mounted on the same side of the printed circuit board as the heat sink while avoiding contact with the heat sink.

Abstract: A pair of travel rails (46) each having an upper surface and a lower surface are laid to extend from on the land (44) into the water (45). Main tires (12) are rotatably disposed on opposite sides of a vehicle body (1), so that they are located between the upper and lower surfaces of the travel rails (46), and so that they abut against the lower surfaces of the travel rails (46) during traveling of the vehicle body on the land. Auxiliary tires (13) are disposed on upper portions of the main tires (12) to abut against the main tires (12). The auxiliary tires (13) are adapted to abut against the upper portions of the travel rails (46) under influence of the buoyancy of the vehicle body (1) during traveling of the vehicle body in the water. Thus, the travel vehicle body (1) can continuously travel on the land and in the water by rotatively driving the main tires (12) to move the travel vehicle body (1) along the travel rails (46).

Abstract: Apparatus for verifying a CRC code of a message transmitted as a succession of sub-blocks comprises dedicated hardware including a linear feedback shift register for deriving a `partial` CRC code for each individual sub-block. These partial CRC codes are held in a store for subsequent combination under software program control. The combination is performed in a iterative manner, each partial CRC code being added modulo 2 to values selected from look-up tables in accordance with the result of the previous step of the iteration. The division of the CRC verification into two operations and the use of precalculated look-up tables facilitate the efficient, simultaneous reception of many messages having interleaved sub-blocks without incurring serious time penalties.

Abstract: The present invention relates to a composition for regulating wrinkles and/or atrophy in mammalian skin comprising treating the skin with a safe and effective amount of salicylic acid and/or additional active component.

Abstract: The present invention provides method for making a wet pressed paper web. An embryonic web of papermaking fibers is formed on a foraminous forming member, and transferred to an imprinting member to deflect a portion of the papermaking fibers in the embryonic web into deflection conduits in the imprinting member. The web and the imprinting member are then pressed between first and second dewatering felts in a compression nip to further deflect the papermaking fibers into the deflection conduits in the imprinting member and to remove water from both sides of the web. The first felt is positioned adjacent a first surface of the web. The imprinting member is positioned between the second surface of the web and the second felt. The second felt has an air permeability which can be greater than that of the first felt.

Abstract: A tilt angle sensor has a body which includes a V-shaped cavity defined by a pair of inclined surfaces which intersect to define a lower end. A roller is disposed in said cavity. A sensing circuit is associated with the cavity to sense the presence of the roller in the lower end of the cavity. The sensing circuit initiates a first signal when the roller is displaced from the lower end of the cavity. A timing circuit is coupled to the sensing circuit for commencing a timing cycle upon the occurrence of the first signal and for providing a second signal after a predetermined time delay. A latch mechanism coupled to the timing circuit latches an output device upon the occurrence of the second signal.
