Abstract: The optical absorption edge of a semiconductor is displaced in an electric field towards lower photon energies. The method according to the invention exploits this electroabsorptive effect in order to measure electric potentials in semiconductor devices. Use is made of a laser probe (LA) which is focussed in the plane (FE) of the signal-carrying element with the aid of optics (L, OL). Since the electric stray fields originating from said elements modify the absorption behaviour of the semiconductor substrate locally, the corresponding potentials can be determined by measuring the intensity of the reflected or transmitted radiation. A large depth resolution of the measurement is achieved by a confocal beam path. <IMAGE>

Abstract: A conventional method consists of wrapping the membrane envelope (with the feed and permeate spacers) around a permeate tube. The sealing of the envelope is achieved by applying a suitable adhesive on the formeate tube and around the edges of the membrane envelope before being rolled to form a spirally wound module. The present method avoids the application of the adhesive before rolling the module. In fact, the module manufacture is the same except that no adhesive is applied and the module is rolled as before. The sealing of the module is achieved by "potting" the two ends of the rolled module. The feed spacer is kept free of adhesive by protecting the spacer by the use of a masking tape which is machined out once the potting agent is dry.

Abstract: The instrument measures optical fibre length by measuring the transit time of an optical pulse signal travelling said fibre. Time measurement is effected by an electronic counter which is cyclically started at the transmission of the optical signal and stopped at its reception. A microprocessor controls the light source so as to make it send the optical pulse signal at a repetition frequency quite uncorrelated with respect to that of the electrical signal counted by the counter. The time spent to travel the fibre is obtained by computing the arithmetic mean value over a great number of counting values supplied by the counter.

Abstract: A multi-orifice ink jet print head array (32) includes multiple drive circuits that drive respective PZTs (16) to cause ink drops to be ejected from respective orifices (28). Each drive circuit includes a voltage divider (36) having a resistor R S . The ink drop ejection velocity is controlled by selecting an appropriate value of R S  for each voltage divider, thereby compensating for imperfections in manufacturing of the print head array. The value of a particular R S  is selected by temporarily connecting the corresponding voltage divider (36A), in which the value of R S  is R I , to assessment circuit (56). The assessment circuit includes a potentiometer (66) with resistance value R POT . Ink drops are ejected at a rapid periodic rate as a camera (102) records the position of the ink drops with respect to a graticule (94) at the time a strobe (100) flashes. The value of R POT  is adjusted until the ink drops are on the graticule as viewed on a monitor (108), at which time R POT  = R T . R S  is then laser trimmed by an amount R T , so that R S  = R F , where R F  = R I  + R T .

Abstract: An apparatus for locally determining the attenuation of an optical signal across a fault in an optical fiber. The local loss test set includes a base unit which houses all of the system's electronic components, except for a photodetector which is located in a remote receiver unit. A remote transmitter unit is also provided; a light source is preferably housed in the base unit, and connected to the remote transmitter by an optical fiber. The remote transmitter utilizes microbending to inject the test signal, and the remote receiver similarly utilizes microbending to withdraw signals. A reference signal is captured from the fiber under test between the transmitter and the fault. A loss signal is captured from the opposite side of the fault, and compared by a processor to yield relative loss measurement (in decibels). The processor checks the loss against preset passing and failing thresholds. The light source is preferably modulated, and the receiver includes a bandpass filter tuned to the frequency of the modulator. A second transmitter may be used with a bidirectional receiver to further enhance the accuracy of the measurements.

Abstract: Improved methods of using an ion trap mass spectrometer, whereby AC voltages supplemental to the AC trapping voltage are used for scanning the trap (10), for conducting chemical ionization experiments, and for conducting MS n  experiments, are shown. In one embodiment a broadband supplemental AC voltage is applied to rid the trap of ions above or below a preselected cutoff mass. This is particularly useful in conducting chemical ionization experiments for eliminating high mass sample ions that are formed when the reagent gas is ionized by electron impact ionization. Likewise, this technique may be used to eliminate low mass reagent ions when conducting an electron impact ionization experiment in the presence of a reagent gas. In another embodiment a non-resonant, low-frequency supplemental voltage is applied to the trap (10) causing trapped ions to undergo collision induced dissociation. Multiple generations of ion fragments may be simultaneously formed in this manner, thereby enabling MS n  experiments. The low-frequency supplemental field has the additional property of causing high mass ions to be ejected from the trap (10) as a function of the magnitude of the supplemental voltage. This property may be used to scan the trap (10), for example, by scanning the magnitude of the supplemental voltage. Likewise, when conducting chemical ionization experiments, this property may be used for eliminating unwanted high mass sample ions, formed during ionization of the reagent gas, from the trap (10).
