IPC: G02F1/141
Filed: 1986-12-01
Abstract: The liquid crystal cell (30) for the optical change-­over switch comprises a pair of transparent substrates (l), a pair of transparent flat electrodes (2) provided on the respective opposing surfaces of the substrates, orientation control films (3) provided on the flat electrodes (2), two pair of comb shaped electrodes (33) respectively provided on the orientation control films (3), and a ferroelectric liquid crystal layer (4) confined between the substrates (l). The optical incidence plane (3l) to the cell (30) is so selected that the plane (3l) is away from the helical axes (9) of the ferroelectric liquid crystal in the cell (30) in the order of somewhat greater than the tilt angle ( ϑ t ) of the ferroelectric liquid crystal. The pair of flat electrodes (2) generate a first electric field (37a) perpendicular to the layer (32) and orient the long axes of the ferroelectric liquid crystal molecules into a first orientation (35a′) parallel to the layer (32) to induce a first refractive index which causes simultaneous reflection of unpolarized light beam (7 + 8) with a predetermined incidence angle ( ϑ ). The two pair of comb shaped electrodes (33) generate a second electric field (37b′) parallel to the layer and perpendicular to the helical axes (9) and orient the long   axes of the molecules into a second orientation (35b′) not in parallel to the layer (32) to induce a second refractive index which causes simultaneous transmission of the unpolarized light beam (7 + 8) with the predetermined incidence angle ( ϑ ).

Abstract: A system for remote chemical analysis includes a quartz halogen bulb as a source of infrared light, quartz fibers leading to and from a sample cell, a non-collinear thallium arsenic selenide, AOTF to perform spectral analysis and a lead selenide detector. Both the AOTF and the detector are interfaced with a microcomputer. Under the control of the microcomputer, the system interprets transmission spectra obtained through the passage of infrared light through the sample cell. Microcomputer interface provides rapid random-access to the RF frequency driving the AOTF, which selects the wavelength of light to be examined and provides routines for sample averaging and the comparison of various reference spectra.

Abstract: Rows of transmitting and receiving electrodes are arranged on a first scale and a second scale which are used in calipers or micrometers and which are displaced relatively to each other. The fact that the capacity value between both sets of electrodes differs depending on the relative displacement positions of both scales is utilized to measure the relative positions of both scales. 
     The transmitting electrodes are provided with a number of A.C. signals having different phases, and the relative positions of both scales can be measured by the signals obtained from the receiving electrodes. 
     Signals of a first specific phase combination are supplied to the transmitting electrodes when both scales are stationary, and the signals received at this time are subjected to positive integration for a predetermined time. Next, transmitted signals of a second specific phase combination, different from the aforesaid phase combination, are supplied to the transmitting electrodes, the signals received are subjected to inverse integration, and the position between both scales is found from the time required until the integral value reaches zero.

Abstract: The burst signal detection apparatus comprises a channel quality detector (104) parallel to an error-­correcting decoder (101). The output or detect signal (5) of the channel quality detector (104) is fed to an ouput circuit (105) together with an arrival signal (4) 10 and a decision signal (6). The channel quality detector (104) recodes an output of the error-correcting de­coder (101),i.e. decoded data,and compares it with the input to the error correcting decoder (101), i.e. data contained in the burst signal (1), thereby estimating a channel error. When the estimated channel error is less than a threshold (a count number), the channel channel quality detector (104) produces the detect signal (5).This signal detecting apparatus allows the probability of reception of erroneous data to become extremely small.

Abstract: Techniques are described for the formation of an abrasive surface layer (14) on an article (12). The surface layer (14) is characterized by a single layer of particles (18) which are evenly spaced apart, in a high density arrangement, within a metallic matrix (16). In the deposition of the particles (18) on the article (12), a vacuum is drawn through a perforated plate (42), wherein the location of each perforation (44) corresponds to the desired location of one particle (18) on the article surface (11). The vacuum holds one particle (18) over each perforation (44) in the plate (42), then the plate (42) is positioned over the article (12) and the vacuum level adjusted so that the particles (18) fall onto the article (12). The matrix (16) is then deposited by plasma arc spraying a superalloy powder. The invention is particularly suited to the formation of an abrasive layer on the tip surface of a blade used in a gas turbine engine.

Inventor: CROWTHER RUSSEL LEE
IPC: G21C3/324
Filed: 1988-03-08
Abstract: An improved channel is disclosed which has a reduced average thickness in its upper portion. The lesser average thickness corresponds to a lower pres­sure difference acting on the channel sides, over the upper portion of the channel. The reduction in average thickness is accomplished by cutting flow trippers into the inner surface of the channel walls and/or cutting grooves into the outer surface of the channel. The axial variation of channel average thickness increases water volume adjacent to the upper part of the channel to provide increased neutron moderation, to minimize the steam void reactivity coefficient, and to provide a greater cold shutdown margin. The material removed to produce the flow trippers increases the cross-sectional area inside the channel and reduces pressure drop in the upper portion of the channel. The flow trippers divert water flowing on the channel walls to the fuel rods adjacent to the channel walls, permitting higher reactor power operation. The flow trippers also permit operation at lower flow rates.
