Filed: 1990-07-11
Abstract: A low impedance class AB buffer stage in complementary transistor technology has its quiescent current stabilized and its operation thereby made more reliable by means of suitable error op-amps (A1, A2) that are supplied with transistor feedback loops (M1, M2) which are connected to the stage's output terminal (21) through resistors (R1, R2). In addition, for full rail-to-rail output voltage capability, transistor switching devices (M5, M6) are added to turn off current through either of the resistors (R1, R2) when the output voltage (V OUT ) of the stage approaches the voltage of either power rail, and also a pair of serially rail-to-rail connected transistors (M3, M4) is connected in parallel with the feedback loops.

Abstract: A speech parameter coding method and apparatus which can quantize a spectrum parameter of a speech signal with a smaller number of bits than ever. A dividing section divides a predetermined order number of spectrum parameters, obtained by division of a speech signal into frames, for each order number of spectrum parameters smaller than the divisional order number. A vector quantizing section searches codebooks for the divided spectrum parameters for each order number and outputs a plurality of candidates of codevector in order of magnitude from the minimum one. An accumulated distortion calculating section calculates accumulated distortions for the entire order number for combinations of codevectors. A minimum judging section selectively outputs a combination of codevectors which minimizes the accumulated distortion thereby to quantize the spectrum parameter.

Abstract: The invention is characterised in that the material to be cleaned is heated under vacuum conditions in a process chamber in such a way that the greases and/or oils, depending on their physical state can be separated off from the material. Alternatively, a further variation of the cleaning process is specified, in which the material to be cleaned is placed in a vacuum chamber. In a first cleaning step, the greases and/or oils adhering to the material to be cleaned are impinged with a solvent similar to their consistency and the mixture forming of solvent and detached greases or oils is fed to an evaporator. In a second cleaning step, the steam forming at the evaporator is fed to the material, on the surface of which the steam condenses and, forming a condensate, disposes of the residual contamination. In a third cleaning step, the steam is fed to a condenser, the condensate obtained from which is in turn fed to the cleaning process as a solvent and in a fourth cleaning step, the vacuum chamber is further evacuated in such a way that residual solvent vapours are completely removed. <IMAGE>

Abstract: A technique relating to automatic excavation by a power shovel is disclosed. An ideal reference locus of movement of a front edge of a bucket is approximated by a plurality of points, positions of the plurality of points and postures of the bucket at these points are previously set. If the start of automatic excavation is assigned by an operation pedal (10) or the like, the position of the front edge of the bucket at the assigned moment is made a position to start excavation. The positions of the plurality of points set relative to a vehicle are calculated for each of excavation sections divided by the plurality of points according to the position to start excavation, and angles of rotation of respective working machines needed to move the front edge of the bucket to the calculated position and to set the bucket to the posture of the bucket set are calculated for each of the excavation sections, and the respective working machines are automatically driven making the calculated angles of rotation target angles of rotation for each excavation section. The bucket, an arm and a boom are thereby automatically controlled so that the front edge of the bucket moves along the ideal reference locus of movement set and the bucket has the ideal posture set by simple operations. Thus, it is intended to improve operation efficiency. After terminating excavation, dropping of load is reduced by automatically driving the bucket so that the bucket is always horizontally maintained in accordance with manual operation of the arm and boom.

Abstract: Diclosed is a method of rapidly checking surfaces for the presence of traces of specific compounds such as certain explosives and drugs. A hand-covering such as a cotton glove is used to wipe surfaces to pick up particles of the specific compound which may indicate the presence of larger amounts or previous contact of a surface by a person who has handled the compound. The particles are transferred - unheated - to collection surfaces of a hand-held sample probe by vacuuming of the gloved hand by the battery-operated probe. Heat is then supplied by a source external to the probe to vaporize the particles, and the vapors are analyzed by a suitable technique such as high speed gas chromatography. The method permits checking of surfaces for explosives at processing rates of up to several samples per minute.

Abstract: Controlled by a signal level produced by a microphone (12), a noise suppressing circuit (25) supplies a first attenuator (16) with a local level which is equal to the signal level and is suppressed to a predetermined output level when the signal level is lower and higher than a predetermined input level. Cooperating with a drive level produced by a second attenuator (17) to drive a loudspeaker (13), the local level makes a comparator unit (21-23) produce a control signal for making the first attenuator give smaller and greater amounts of attenuation to the signal level with the drive level rendered by the second attenuator low and high when positive and negative values are had, respectively, by an input difference equal to the local level less the drive level. Preferably, the local level is suppressed by a level difference had by the signal level above the predetermined input level.

Abstract: A circuit for detecting a frame synchronizing signal and a circuit for detecting subframe synchronizing signals in the frame synchronization data transmission are presented. The former circuit generates a first signal which is at the logic 1 exclusively during the period that the frame synchronizing signal is received, and produces the logical product of the first signal and the data signal, the logical product corresponding to any error present in the frame synchronizing signal. In the latter circuit, a window pulse signal which corresponds to the bits of the subframes assigned to the subframe synchronizing signal is first produced, the bits of the data signal which are synchronous to the window pulse signal are next extracted, and an error bit is selected by excluding corrects bits from the extracted bits of the data signal. In this way an error bit in the synchronizing signal in the frame synchronization data transmission is detected.
