摘要： A vehicle brake booster and master cylinder assembly has a vacuum suspended booster section which is controlled by movement of the vehicle brake pedal. A hydraulic booster section is in series with the vacuum suspended booster section, and a master cyclinder unit is in series with the hydraulic booster section. The assembly is so arranged that in normal operation the vehicle operator obtains boosted brake actuating pressures by operation of the vacuum suspended booster which acts through the hydraulic booster mechanism without operating the hydraulic booster. When greater brake actuating pressures are required, as indicated by increased brake pedal force exerted by the operator, the vacuum booster reaches its limit or runout condition and the hydraulic booster is operated so as to continue the increase in master cylinder output pressure. If still further master cylinder output pressure is required when the hydraulic booster has reached its runout condition, the master cylinder is actuated manually through mechanical force transmitting elements which are parts of the booster sections. In one embodiment the assembly utilizes a single hydraulic fluid for the hydraulic booster section and for the master cylinder and brake apply circuitry. In another embodiment the hydraulic booster section is operated by a separate fluid circuit which is fluidly independent of the master cylinder and brake apply pressure circuitry.

摘要： A vehicle hydraulic power brake and steering system has a hydraulic brake booster provided with a mechanism for operating a switch to indicate loss of hydraulic power, and for operating a control valve for admitting hydraulic pressure from another source such as an accumulator. The mechanism includes an actuating bar mounted in a recess formed in the wall of the hydraulic brake booster power cylinder and lying in the power chamber of the booster. The bar extends axially for a distance substantially equal to the power stroke of the power piston. An annular valve seat has a ramped groove which actuates a ball positioned in a radially extending passage of the booster piston and engaging the actuating bar in rolling contact. So long as hydraulic power pressure is available, the ramped groove does not move the ball radially outward. When this pressure is lost, the annular valve seat will be moved axially relative to the power piston, forcing the ball radially outward and moving the actuating bar radially outward to close the warning switch and to open the accumulator control valve.

摘要： The present invention provides electronically conducting polymer films formed from photosensitive formulations of pyrrole and an electron acceptor that have been selectively exposed to UV light, laser light, or electron beams. The formulations may include photoinitiators, flexibilizers, solvents and the like. These solutions can be used in applications including printed circuit boards and through-hole plating and enable direct metallization processes on non-conducting substrates. After forming the conductive polymer patterns, a printed wiring board can be formed by sensitizing the polymer with palladium and electrolytically depositing copper.

摘要： A brake assembly includes a guide spring for returning a parking brake actuator arm to a release position and which serves to guide an apply cable into engagement with the actuator arm during assembly. The guide spring is inhibited from deflecting during insertion of the cable by a retaining spring that spans across the opposing lower brake shoe ends at the adjuster link and which includes an extending tail positioned adjacent the guide spring.

摘要： A low voltage vacuum field emission device and method for manufacturing is provided. The devices are fabricated by anodizing a heavily doped silicon wafer substrate (12) in concentrated HF solution, forming extremely sharp silicon tips (18) at the silicon to porous silicon interface. The resulting porous silicon layer is then oxidized, and a metal film (22) is deposited by evaporation on the porous silicon. Silicon substrate (12) is the cathode, and metal film dots (22) are the anodes. The I-V characteristics for the field emission devices follow Fowler-Nordheim curves over three decades of current. The I-V characteristics are also utterly independent of temperature up to 250.degree. C. When the oxidized porous silicon layer (OPSL) is about 5000 .ANG., substantial current is obtained with less than 10 volts. Recent experiments leave no doubt that the charge transport is in the vacuum of the pores. A silicon wafer that contains an OPSL may prove to be a very useful material for the fabrication of low voltage, low noise field emitters for vacuum microelectronics.

摘要： An integrated anti-lock braking (ABS)/traction control (TC) braking system is provided which includes a controller cognizant of a rotational condition of a wheel, a master cylinder, an actuator with a bore, the bore having a first fluid connection with a master cylinder and space therefrom a second fluid connection with a brake, a first normally open solenoid valve for isolating the master cylinder from the wheel brake when the controller places the system in an ABS or TC mode, and a hollow primary piston mounted within the bore along first, second and third spaced sealed peripheries having a first port connecting the interior of the primary piston with its exterior between the first and second sealed peripheries and communicating with the second fluid connection of the bore. The primary piston also has a second port fluidly connecting an end of the primary piston most adjacent to the bore first fluid connection with the interior of the primary piston and the primary piston having a check valve mounted within the second port and the primary piston has a third sealed periphery generally adjacent the bore first fluid connection. A secondary piston is mounted within the primary piston movable in a direction towards the bore first fluid connection to pressurize the brake and movable in an opposite direction to release the pressure within the brake, the secondary piston has an extreme position with respect to the primary piston wherein the secondary piston opens the check valve and further movement of the secondary piston causes the pistons to move in unison pressurizing the wheel brake. A reversible motor connected with a gear train, drive screw and nut moves the secondary piston in response to signal give by the controller.

摘要： A vehicle wheel brake system having a service braking section and a wheel lock control (ABS) section is provided. Under certain conditions the wheel lock control section may not be able to generate sufficient pressure to operate the vehicle wheel brakes when the master cylinder output pressure has been isolated from the wheel brakes. When such conditions occur, the displacement piston of the ABS control section moves to open a bypass valve which connects master cylinder output pressure to the vehicle wheel brake even though the ABS system has isolated it from that wheel brake. The opening of the bypass valve effectively returns the vehicle braking system to service braking until the vehicle operator releases the brake system.
