Title: Controlling front/rear brake force distribution in dual-circuit brake system for motor vehicles
Inventor: LEIBER HEINZ
IPC: B60T8/26
Filed: 1984-05-17
Abstract: Variable brake force adjustment for the front and rear axles is achieved by using the solenoid valves (15, 16, 17) provided in an anti-skid system. For this purpose, actual value sensors (22, 23) for the brake pressure are disposed between the solenoid valves (15, 16) and the front wheel brake cylinders (10, 11) and their output signals are fed to a respective four- pole network (27, 28) having a transmission function.

Title: Indirectly heated cathode manufacture
Inventor: KOIZUMI SACHIO
IPC: H01J9/04
Filed: 1986-03-06
Abstract: The manufacture of an indirectly heated cathode with a black coating 6d inside the cathode sleeve 6c housing the heater is facilitated by providing a cathode sleeve 6c which contains a reducing material, eg. Cr or possibly Mo, such that a thin metal oxide film, eg. of tungsten oxide or an oxide of Ag, Ti or Mn, previously formed on the internal surface of the cathode sleeve is, when heated, reduced by the reducing material in the sleeve to form the black coating. The metal oxide film may be vacuum evaporated from a crucible, Fig. 3 (not shown), or, if the cathode includes a heater coated with dark tungsten particles, then a tungsten oxide coating may be sputtered onto the sleeve from the heater during a preliminary oxidation heating at 400 DEG C in air. The heating step to reduce the metal oxide film may be the normal aging and activation process which the cathode, eg. for a CRT, is subject to. …<??>The indirectly heated cathode manufactured by this method has the shorter emission warm up time for the emission of electrons and lower power consumption compared with those manufactured by the conventional method. …<IMAGE>…

Filed: 1986-03-25
Abstract: A wavefront phase modulator and method of manufacturing the same in which actuators used to deform the mirror surface of the phase modulator are manufactured as large blocks comprised of layers of electrodistortive material interleaved with electrically conductive layers. The blocks include connectors for making electrical connections through the top and bottom of the blocks to selected conductive layers. The blocks are fastened to a base made of an electrically insulating material. A plurality of electrical connections pass through the base and permit connection of individual actuators through the connector on the bottom of the blocks to electronic circuits for operating the actuators. After the blocks are fastened to the base, the blocks are cut in directions perpendicular to the base to produce individual actuators. An electrically conductive face-plate having a mirror surface on one side is fastened to the actuators with an electrically conductive material. The faceplate makes electrical contact through the connector at the top of each actuator with alternate ones of the conductive layers in each of the actuators. The actuators may be selectively operated to distort the faceplate by applying electrical signals between the faceplate and one or more of the electrical connections in the base. <IMAGE>
