摘要： An areal array of tubular electron sources is disclosed for producing multiple directed electron beams. Sources (10) are located in a parallel array between a conductive back plate (12) at a closed end of the tubes and a conductive face plate (14) having holes therein aligned with the second open end of each of the electrode tubes (10). An electrical current source (30) is connected between the back plate (12) and face plate (14) to resistively heat each of the sources (10) to a temperature high enough for thermionic electron emission. Electron beams (34) are produced from within each of the tubular electrodes (10). Extraction means which may include a magnetic field from a coil (29) and an extraction lens (18) tends to withdraw the electrons from within the sources (10) in an intense, collimated beam (34). Beams (34) are accelerated toward a target (28) through a beam deflection unit (22) having holes (24) associated with each of the electron beams (34 ). Beam deflection plates (26) within each of the holes (24) deflect the electron beams (34) to impact selected points on a target (28).

摘要： A load representative air shock absorber pressure system will add to the force exerted by the proportioner spring to increase the pressure point at which the proportioner begins proportioning operation in accordance with increase in vehicle load. Vents are provided to prevent the mixture of air and hydraulic brake fluid in the proportioner. The proportioner may be a part of the wheel cylinder assembly or may be installed in the master cylinder.

摘要： A small take-up piston moves outward during the first increment of hydraulic pressure, taking up the clearance with low fluid displacement because of small size of this piston. As a predetermined pressure level is reached, the take-up and power pistons are locked together and thereafter both pistons move outwardly in unison. This greatly reduces the displacement over a single stage piston traveling the same distance. It allows additional retractive clearance without commensurate displacement required to reactuate the caliper.
摘要翻译：在第一次增加液压的同时，一个小的吸收活塞向外移动，因为活塞的体积小，所以使用低流体位移的间隙。当达到预定的压力水平时，吸收和动力活塞被锁定在一起，然后两个活塞一起向外移动。这大大降低了在相同距离上行驶的单级活塞上的位移。它允许额外的回缩间隙，而不需要相应的位移来反映卡尺。

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 cylinder 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： An improved apparatus for examining the crystal lattice of a semiconductor wafer utilizing x-ray diffraction techniques. The apparatus is employed in a method which includes the step of recording the image of a wafer supported in a bent configuration conforming to a compound curve, produced through the use of a vaccum chuck provided for an x-ray camera while the entire surface thereof is illuminated simultaneously by a beam of incident x-rays which are projected from a distant point-source and satisfy conditions of the Bragg Law for all points on the surface of the wafer.

摘要： A single-piece piston in a dual diaphragm brake booster provides mounting for both diaphragms and support and guide sections for the primary and secondary piston bearings while eliminating the threaded assembly of prior two-piece pistons, or other interlocking arrangements, to make a piston assembly out of a plurality of pieces. The secondary support plate and the secondary diaphragm slip over one end of the piston without requiring piston parts to be interlocked afterward. The diaphragm seals on the outside of the piston. The primary support plate and primary diaphragm are similarly installed. The booster chamber divider and bearing are installed between the two support plate and diaphragm sub-assemblies. A reaction chamber containing reaction means is positioned radially inwardly of one guide and support section of the piston located between the two diaphragm and mounting plate means. A control valve chamber is similarly positioned radially inwardly of the other support and guide section of the piston. The chambers are separated by an apertured wall in which the air valve is reciprocably mounted, the air valve also acting to transmit force mechanically from the input push rod to the reaction means and thereafter to the output member. In one arrangement the reaction means is a reaction disc of a well-known type, and in the other arrangement the reaction means is a reaction lever system, also of a well-known type.
