Abstract: PURPOSE: To enable connection to low pressure and high pressure passages with a balance piston valve housed in a valve body.  
     CONSTITUTION: When a pilot valve 14 opens with an increase in a pressure of a chamber 17, the flow of a fluid produces a differential pressure before and after an orifice 16. The chamber 17 is communicated to a charging port 11 and the pressure of chamber 17 drops to produce a differential pressure before and after the orifice 16. When the differential pressure exceeds a specified level, a spool 23 is displaced to have a main port 10 communicating to the charging port 11 through a relief hole 24 thereby preventing a rise in the pressure in a high pressure passage 4. When the main port 10 is in a low pressure passage, the spool 22 is displaced to the left to have the charging port 11 communicating to the main port 10. A balance piston valve 13 comprises the spools 22 and 23.

Abstract: Electrical signals are measured (analyzed and displayed) with subpicosecond resolution by electro-optic sampling of the signal in an electro-optic crystal, the index of which changes in response to the electric field produced by the signal, in accordance with the Pockels effect. The crystal is disposed adjacent to a transmission line along which the signals propagate the line may be a coplanar wave guide having a plurality of parallel strips of conductive material on the surface of the crystal. The crystal may be disposed adjacent to and in the fringe field of a line on a substrate, which may be part of an integrated circuit, for measuring signals propagating along the line during the operation of the circuit. A beam of short optical (laser) sampling pulses in the picosecond range is focused so that the region where the beam is confocal is disposed where the field is parallel in the crystal. The confocal region (where the optical wavefront is planar is preferrably close to the surface of the crystal and perpendicular to the optical axis of the crystal. The optical pulses transmitted through the crystal are processed to provide a display affording a measurement of the electrical signal.
