Abstract: A process for the production of a sodium-filled valve in which the sodium is introduced into a hollow valve stem through a filling bore of relatively large diameter and which is sealed through a plug and/or usual welding. Subsequent to the closing off of the filling bore, the hollow inner space is evacuated through a passageway having a small cross-section and is thereafter sealed vacuum-tightly in a vacuum through either welding or soldering. Through the evacuation of the hollow space there is avoided any kind of oxydation of the sodium and thereby any change. Moreover, no froth or foam formation is encountered so as to facilitate the presence of an extremely constant heat transfer.

Abstract: A method and tool (40) for replacing jet pump holddown beams (17) in a nuclear reactor is disclosed. The tool (40) has an inner frame (41) and an outer frame (28). Each frame defines two spaced plates (33 and 30, respectively). Each inner and outer plate has a jaw (34, and 31, respectively), defined therein. The frames (41, 23) are movably nested such that the jaws (34, 31) of adjacent inner (33) and outer (30) plates form two pairs of opposed jaws (31, 34) each sized and positioned to receive and hold one of two protruding members (20) of the holddown beam (17) such that the beam (17) is suspended between the pairs of opposed jaws (31, 34).

In installing a beam (17), this procedure is substantially reversed, care being taken to position the beam (17) properly for engagement of the keeper (26).

Abstract: The subject invention conserves memory real estate by employing ROM cells which are FETs or non-FETs depending upon the programming. Each cell comprises a gate, a source and drain region and provision for connections to bit and word lines. Programming is achieved by a mask which permits doping of the source and drain regions to comprise FETs for the cells indicative of one state of logic while precluding doping of the source and drain regions to complete the channel in the cells comprising the other state of logic. Also, the FETs are fabricated, their contacts extending linearly between bit lines which are preferably diffused lines, and the word line making direct contact with gates of the linear cells. The process simplifies the number of steps required to manufacture the FETs and non-FETs by simply providing the programming after the basic cells are formed. Such unprogrammed structures may be inventoried and simply programmed i.e.

Abstract: Mounting silicon devices on a ceramic substrate creates considerable problems when the device has a geometry, such as being very long relative to its width, due to flatness and thermal mismatches. In the present invention a thin silicon substrate is interposed between base and device, the substrate of a geometry which reduces flatness and thermal mismatching to acceptable levels. Also the use of a silicon substrate enables well developed and easily provided silicon technology to form conductor patterns for interconnecting between device and base, avoiding problems of producing such conductor patterns on the ceramic base. The invention is particularly useful for the mounting of linear devices, such as linear imagers, which can have a length to width ratio in excess of 20:1.

Abstract: A mechanical and electrical connection for a piezoelectric member of polyic material such as polyvinylidene fluoride, and method for forming such a connection. To form the connection, the piezoelectric member is first masked to prevent a preselected portion of its surface from being coated during subsequent coating operations.

The masked piezoelectric member, the electrically conductive member, and (incidentally) the mask are then coated with a conductive coating such as sputtered gold to electrically connect the conductive member to the piezoelectric member. The mask can now be removed from the piezoelectric member if desired, although it can be left in place as a convenient vise.
