Abstract: A high-density circuit has a plurality of conductors formed in grooves in a ceramic substrate, the conductors having a height less than that of the walls of the grooves. The substrate is embossed with a pattern of grooves corresponding to the grooves in an electroform made from a master tool. The same master tool is used to form a stencil which mates with the grooved substrate. A cermet paste is pushed through the stencil, so as to fill the bottom region of the grooves, and the stencil is then removed, leaving only the paste at the bottom of the grooves. The substrate is then fired, causing the substrate to harden, and causing the cermet to become conductive and to become firmly bonded to the substrate. Because the stencil and the substrate are made from the same, or replications of the same, master tool, the cermet paste can be laid down with great precision, thus enhancing the quality of the product, and reducing the cost of its manufacture.

Abstract: The inventor, Ian Popoff, of Encinitas, Calif., wishes to disclose the novel utility of the Passenger Safety Handlebar. The Passenger Safety Handlebar is a fixed-mounted device to be used with in-line-seating arrangement vehicles, such as motorcycles, snowmobiles, personal watercraft, all-terrain vehicles, and the like, to improve passenger safety and stability while using such vehicles. What is novel with respect to the Passenger Safety Handlebar is primarily the secured-mounting properties of the device to the vehicle (as opposed to the driver of such vehicle), which are not observed in the prior art. Second, the innate nature of the Passenger Safety Handlebar predisposes it against action or movement of either the passenger or driver to each other. Further, the actual location of the Passenger Safety Handlebar is novel with respect to prior art, in that it is forward of the driver of the vehicle, rather than lateral or behind.

The controller (16) modifies the motor control signal to compensate for the friction.

Abstract: The fine jet control type sound absorption system of this invention, aimed at absorbing low-frequency sound with both discrete frequency and broadband frequency to the same degree as already existing acoustic lining can do, is composed of two parts. One is a barrier wall covering an air space in which the concerning low-frequency sound propagates and having a multiplicity of small holes formed therein. The other is the means for causing a fine jet passing through these small holes into or out from the air space. This sound absorption system realizes a fine jet in the vicinity of the barrier wall for the purpose of canceling the sound inside the air space by means of the interference of the sound with the fine jets. Any of or a combination of shape of small holes, jet ejection angle or suction angle, amount of jet flow, thickness of a barrier wall back layer and air flow angle at which secondary air flows into the barrier wall back layer is selected.

Abstract: A broadband noise barrier includes Helmholtz-type resonator cavities. The barrier has a core section made up of one or more layers of cellular cavities of varying sizes sandwiched between a substantially planar face section placed toward a noise source, and an impermeable, substantially planar base section placed away from the noise source. The face section has apertures of specified sizes to permit disturbed air from the noise source to interact with the cavities in the core section. The variable cavity sizes permit resonant interactions with selected frequencies commonly associated with traffic noise, thus providing broadband acoustic absorption. Since the performance of the system derives from the resonator configuration rather than the constitutive properties of the materials used, the structure requires neither special materials, unconventional manufacturing processes, nor thick, heavy panel structures.

Abstract: An existing diffuser is modified by creating through-holes in its diffusive surface that allow sound to travel through the diffuser to the rear of it where an absorptive material is provided. The absorptive material may be made of any suitable material such as fiber glass, foam or mineral wool. The cut-off frequency between diffusion and absorption may be “tuned” or adjusted by varying the total volume of holes made within the diffuser, and by determining the particular cavities (and their depths) that are chosen to be modified through the provision of holes. In each embodiment of the present invention, holes or slots are formed in a diffusive surface and such holes or slots form one component of a resonant absorber. The perforations can be any shape or size and by varying the perforation and cavity size, the inventive devices may be “tuned” to begin to absorb sound below a desired chosen frequency.

Abstract: A venting or pressure release system releases pressure from a transmission housing through which extends a transmission shaft. A lower part of the transmission housing forms a collector in which fluid collect. A conduit communicates the collector with a storage container which is substantially sealed against the transmission housing. An overpressure in the transmission housing forces fluid from the collector through the conduit into the storage container. A pressure-release conduit communicates the transmission housing above the collector to the storage container. A shutoff device closes the pressure-release conduit when the transmission shaft is rotating and opens the pressure-release conduit when the transmission shaft is not rotating. This makes possible a rapid compensation of fluid after the transmission has been turned off so that the fluid level can be reliably determined. The shutoff device may be a pilot-controlled valve or a fluid barrier.

Abstract: The invention relates to a brake disk/hub assembly for vehicle disk brakes comprising a hub and a brake disk, which is arranged thereon in a manner that prevents it from turning. The brake disk is arranged in the axial direction of the hub in such a manner that it can be axially displaced against an elastic pretensioning exerted by a number of spring elements. To this end, each spring element has a retaining section by means of which it is fixed to the hub. Each spring element also comprises at least one spring section, which rests against at least one assigned intermediate element that is essentially arranged between the hub and the brake disk. The inventive design is advantageous by virtue of the fact that the spring elements are not in direct contact with the brake disk thereby effectively preventing the spring elements from becoming thermally overloaded. The functional reliability of the spring elements can thus be maintained over a long period of time.
