Abstract: In a steady state free precession (SFP) magnetic resonance imaging method, after each pulse (1) of an applied train of phase coherent RF pulses which excite magnetic resonance spins in a region of a body being examined, magnetic field gradients (7, 11) are applied to encode the excited spins and the encoded spins are detected, and at least one further magnetic field gradient (15, 17) is then applied to rephase the spins by the time the next RF pulse is applied.The method finds particular application where the applied encoding gradients serve to encode the spins in such a manner as to allow a multi-dimensional Fourier transform technique to be used to reconstruct an image.The method allows more rapid data acquisition than has been possible hitherto in SFP imaging.

Abstract: In an information recording and reproducing apparatus using a disc-shaped information recording medium having a plurality of recording tracks, each of which recording tracks is divided into a plurality of sectors, to record and reproduce information on and from the information recording medium on a sector-by-sector basis, when a target sector (S n ) is detected to be a defective sector whose address can not be reproduced, in the first place, a reference sector (S n-k ), which is positioned preceding the defective target sector and whose address can be reproduced, is detected. Then, a rotational latency time from the detected reference sector (S n-k ) to the defective target sector (S n ) is measured by using:
     (l) a time measuring circuit (l3) for measuring the rotational latency time per se; or   (2) a counter circuit (l4) for counting the number of a sector mark or sector marks (ll) which indicate the presence of an associated sector or sectors and which are detected during the rotational latency time,        so that the defective target sector (S n ) may be taken to be a normally detected target sector whereby information may be recorded and reproduced on and from the defective target sector (S n ), thereby making it possible to perform recording and reproduction of informa­  tion on and from a defective sector whose address can not be reproduced.

Abstract: Leu-3⁻ cells surviving infection with the AIDS retrovirus can be induced with IUdR to express infectious virus. A cellular clone (8E5), isolated by limiting dilution of a mass culture of survivor cells, was found to contain a single, integrated, defective provirus that was constitutively expressed. Although IUdR treatment of 8E5 cells failed to induce infectious virus, cocultiva­tion with Leu-3⁺ cells generated the characteristic syncytia associated with acute AIDS retrovirus infec­tion. The single integrated copy of proviral DNA directs the synthesis of all major viral structural proteins except p64 and p34 as monitored by immunoblotting. Diag­nostic reagents and kits in accordance with the present invention are also described.

Abstract: In speech recognition, speech values derived from the speech signal are compared with reference values for the individual words of a predetermined vocabulary. A known method of reducing the recognition error rate is to take into account speech patterns, the effect of which is to permit only selected sequences of words. From the theory of formal languages a class of speech patterns known as "context-free grammar", which characterises a relatively flexible speech pattern, is known. To apply this speech pattern in a technical process for recognition of a speech signal, two lists are used, which give the correlation between words and predetermined syntactical categories and the correlation of these categories where necessary with two other categories. Both lists are used for each new speech signal; the system always looks retrospectively to see which category best explains the previous speech segment. At the end of the speech signal, it is possible, on the basis of the category which gives the complete sentence, to trace back to the sequence of the words which gave the smallest total distance sum and which also fits into the speech pattern specified by the two lists.

Abstract: A system for dampening vibratory motion of a pendulous compensator (18) in a laser projector (10) includes a beam splitter (32) which diverts a portion of a laser beam deflected by a mirror mounted on a cantilever beam (22) of the compensator (18), and a photocell device (34) having a pair of photodetectors (44, 46) positioned to receive the diverted laser beam portion (42) and sense oppositely varying proportions thereof corresponding to the displacement of the position of the deflected laser beam (26). Two output signals are produced corresponding in magnitudes to the respective proportions of the diverted laser beam portion (42) sensed by the photodetectors (44, 46). A difference amplifier (40) takes the difference of these output signals to produce a first electrical signal having a polarity and magnitude representing the direction and amount of motion of the cantilever beam (22). A derivative circuit (48) takes the derivative of the first electrical signal with respect to time to produce a second electrical signal having a polarity and magnitude representing the direction and rate of movement of the cantilever beam (22). An electrical coil (52), having a magnet (54) reciprocally movable relative thereto which is linked to the cantilever beam (22), produces a magnetic force related in polarity and magnitude to the second signal to cause the magnet to resist the vibratory movement of the cantilever beam (22).

Abstract: The invention relates to an autoclave laminating device for producing multilayered circuit boards, in which the stacks of circuit boards to be laminated, lying between two pressing plates in a chamber which can be provided with overpressure and can be heated, are surrounded by a covering which, together with its bearing surface, produces a space which is enclosed on all sides and can be turned into a vacuum chamber by extracting the gas inside it. This vacuum chamber has until now been formed by a sheet which was held together by double-sided adhesive tape, a nonwoven mat being laid between the stack of circuit boards and this sheet to produce extraction channels. However, due to this vacuum chamber being produced manually, until now it has not been possible to automate the method. The invention prevents this disadvantage by the vacuum chamber (1) being formed by a sealing mat (3), consisting of temperature-resistant material, being spread over the stack of circuit boards (4) and clamped into a two-part sealing frame (2a, 2b). A Teflon-coated woven glass fabric (5) is laid between the sealing mat (3) and stack of circuit boards (4) to form the extraction channels and the extraction grooves (6), required for extraction of the gas, are made directly in the laying table (7), on which the stack of circuit boards (4) lies. <IMAGE>
