Abstract: An apparatus and process for the construction of a cruciformed section control rod is disclosed. The control rod is constructed of square exterior sectioned tubes with central cylindrical volumes for the contain­ment of neutron absorbing poisons. In the process, these tubes are welded together at the corners of the square sections to form the planar members of the cruciformed shaped rods. An apparatus and process is disclosed in which the rods (T) are all held by a jig (J1,J2) in the same configuration as is ultimately fabricated. Thereafter, the jig is drawn through fixtures, which fixtures accurately guide the rods to be joined by welding past a laser welding unit preferably comprising paired and opposed laser welding heads. By the expedient of positioning the laser and rapidly welding the braced together tubes by the laser, control rod fabrication occurs. There results a solid, integral control rod constituting a suitable pressure vessel for neutron absorbers for control of nuclear reactions.

Abstract: A measuring apparatus of the present invention measures the constituent concentration of a specimen after loading into the apparatus a test piece having a test material which develops coloring as a result of a reaction with the constituents of a specimen. When the apparatus detects that the test piece having the test material has been loaded, it automatically begins to measure the constituent concentration of the specimen. That is. after the loading of the test piece is detected, a predetermined time period is measured. During this time measurement, the time period is displayed at a predetermined time interval. After the time measurement of this predetermined time period is terminated, the test material is irradiated with a light, and the intensity of the light from the test material is detected. The constituent concentration of the specimen applied to the test material can be determined on the basis of the reflected light intensity thus detected. Furthermore, this measuring apparatus can detect a reverse insertion of a test piece, and is constructed so as to disable the measurement of the constituent concentration of a specimen if supplementary information to be stored along with measurement information has not been set.

Abstract: The power density of a pulsed laser beam for irradiating a sample is adjusted to break down the sample into the form of a plasma. After the momentary breakdown of the sample into the form of a plasma, ions are generated having a high charge. Then, after a certain time elapses, the ions having a high charge recombine with the electrons in the plasma to provide monovalent or low valent ions. These low valent ions are taken out of the plasma and introduced to a mass spectrometric apparatus.

Abstract: Method and apparatus are disclosed for conditional acquisition of potential measurements in integrated circuits, with the aid of electron-beam probes. The conditional acquisition enables display of waveform images which permit diagnosis of the causes and/or origins of failure in circuits which fail intermittently. Data is acquired in the normal manner on each pass through the test pattern. At the end of each test pattern execution a pass/fail signal from the tester exercising the circuit is used to reject or accept the acquired data. In this fashion, it is possible to accumulate only that data which carries information about the failure of interest and to reject data which does not. Over several test pattern repetitions it is possible to display only that data which shows the failure. Engineers are thus able to efficiently diagnose intermittent failures without the need to change device operating parameters. 
     In one form of the invention, (a) initially a first buffer is defines as a "good-­data" buffer and a second buffer is defined as a "temporary-data" buffer; (b) the circuit is probed during application of a test vector pattern to acquire data; (c) the acquired data is summed with stored data from the "good-data" buffer, and the sum is stored in the "temporary-data" buffer; (d) a determination is made whether the circuit has failed to operate as expected in response to the pattern and, if the circuit has failed to operate as expected, the second buffer is re-­defined as a "good-data" buffer and the first buffer is re-defined as a "temporary-data" buffer; and (e) steps (b)-(d) are repeated, such that the data stored in the "good-data" buffer represents failing operating of the circuit.

Abstract: Time consuming and reusable queries are handled in an object oriented database management system (11) by provid­ing a persistent stream object class. The persistent stream object class is a subclass of the stream class which is typically provided to encapsulate the results of a query. The persistent stream class inherits all the attributes and methods of the stream class but also in­cludes a "save" method for saving the results of a query. When a query names a persistent stream as its object, the query results are saved. The query may also be performed in background or batch mode. All time consuming and reusable queries are performed by sending a query message to the persistent stream class, to thereby automatically save the query results.

Abstract: Contamination levels in plasma processes are reduced during plasma processing, by prevention of formation of particles, by preventing entry of particles externally introduced or by removing particles spontaneously formed from chemical and/or mechanical sources. Some techniques for prevention of formation of particles include interrup­tion of the plasma by pulsing the source of plasma energy periodically, or application of energy to provide mechani­cal agitation such as mechanical shockwaves, acoustic stress, ultrasonic stress, vibrational stress, thermal stress, and pressure stress. Following a period of ap­plied stress, a tool is pumped out (if a plasma is used, the glow is first discontinued), vented, opened and flaked or particulate material is cleaned from the lower elec­trode and other surfaces. A burst of filtered air or nitrogen, or a vacuum cleaner is used for removal of deposition debris while the vented tool is open. Follow­ing this procedure, the tool is then be used.for product runs. Alternatively, improvement of semiconductor process yields can be achieved by addition of reagents to getter chemical precursors of contamination particulates and by filtration of particulates from feedgas before plasma processing. The efficiency and endpoint for the applied stress are determined, by laser light scattering, using a pulsed or continuous laser source, e.g. a HeNe laser.
